DETAILED DESCRIPTION OF THE EMBODIMENTS

[0066] “Saline” and “saline solution” as used herein mean water containing salt. Water may be sea water or not sea water. For human use, both sea water and fresh water are purified before consumption. Salt is sodium chloride. Saline solutions are used in a wide variety of medical applications. For example, “normal saline” is the commonly used term for a solution of 0.90% w/v of sodium chloride (NaCl). Normal saline is frequently used in intravenous drips for patients unable to take fluids orally to prevent dehydration. Normal saline is also used to flush wounds and skin abrasions. Another application of saline solution is as a rinse for contact lenses. Saline is also used as a nasal cleanser, but does not inhibit or reduce the causes of nasal congestion, such as rhinitis or sinusitis.

[0067] Saline solution also is frequently used in nasal washes to treat some of the symptoms of the common cold or other ailments adversely affecting the nasal cavities. By irrigating the nasal passages with saline, inflammation can be reduced. Also, more concentrated (“hypertonic”) solutions of NaCl, can have therapeutic uses. For example, 7% NaCl/water solutions are considered mucoactive agents and as such are used to hydrate thick secretions (mucous) in order to make it easier to cough up and out (expectorate).

[0068] Another chemical substance useful in medical treatments is carbon dioxide. One example is the use of diluted carbon dioxide by inhalation for treating symptoms related to headaches, allergies, asthma, nervous disorders, and other common ailments, which was demonstrated in the 1940s and 1950s. Another example is the use of high-concentration, non-inhaled carbon dioxide, delivered to the nasal passages locally. This type of treatment may provide fast relief without the adverse side effects of systemic drugs that are inhaled, ingested, or injected.

[0069] Carbon dioxide, when dissolved in water, and, as in the present invention, when dissolved in saline, will dissolve so as to include dissolved gas, as well as some in situ formed carbonic acid and some possible other ionic constituents. This formed carbonic acid functions as a separate active so as to aid in the reduction of the pH of the dosage and to thus function as an antibacterial agent and with efficacy in disrupting biofilms. In the present invention, carbonic acid is formed when the carbon dioxide is dissolved, and in some embodiments no additional carbonic acid is added, whereas in other embodiments, additional carbonic acid is added to the dosage. In those embodiments wherein only the in situ formed carbonic acid is present, the amount of carbonic acid depends upon temperature, pressure, pH and carbon dioxide dissolved-then it is the amount that forms for that stoichiometry at equilibrium. If additional carbonic acid is added, then equilibrium shifts and the amount of carbonic acid in the dosage is increased above in situ formation equilibrium. About 0.01% up to and including 0.4% by weight of carbonic acid based on the total weight of the dosage is the desired range, although more or less could be included. Preferred range of carbonic acid is 0.01% to 0.1%, and most preferred is 0.02% to 0.08% by weight based on the total weight of the dosage.

[0070] The present invention involves combining the beneficial therapeutic effects of saline treatment and carbon dioxide/carbonic acid treatment that, relative to either component, is an improved and synergistic therapy with unexpected favorable consequences. In this way, the beneficial effects of the saline, such as reduced inflammation and expectoration of mucous, are combined with the beneficial effects of carbon dioxide therapy, such as relief from headaches, allergies, asthma, nervous disorders, and other common ailments. Further, the saline moisturizes the nasal cavities and acts as a base host for the carbon dioxide as it acts on the nasal cavity walls. (It is hypothesized that at least some of the carbon dioxide is adsorbed by the saline.) In addition, the saline reduces any slight burning that might otherwise be felt from the carbon dioxide. In this way, the benefits of saline treatment are supplemented by the benefits of carbon dioxide treatment, and the benefits of carbon dioxide treatment are supplemented by the benefits of saline treatment. This combination of utilizing the saline to perform at least moisturizing and other beneficial affects while carrying and enhancing the delivery of the carbon dioxide is an unexpected synergistic result thereof. By the methods and devices of the present invention unexpected results are obtained. Specifically, much smaller dosages of carbon dioxide (orders of magnitude less) are used to obtain better results than gaseous carbon dioxide, and the kill rate as shown by biofilm independent testing is evident versus saline, wherein no kill rate is observed. These and other benefits are shown below.

[0071] In addition to the benefits listed above, the present invention device using carbon dioxide and saline nasal delivery methods and treatments have other synergistic benefits that are not available from either saline treatment or carbon dioxide treatment alone. For example, the presence of dissolved carbon dioxide in the saline solution means that the solution will be carbonated; the effervescent effect of the carbon dioxide helps the saline solution to mix more energetically against the interior surface of the nasal cavity or cavities. This improved mixing allows the saline treatment to be more effective Another potential advantage of combining carbon dioxide and saline treatments is that in some embodiments, with sufficient pressure and a proper nozzle, the carbon dioxide can act as a carrier gas for the saline, allowing the saline solution to be aerosolized. This means that a more well distributed delivery occurs.

[0072] To summarize the advantages and benefits of the present invention, the combination of controlled delivery carbon dioxide and saline provides the following: it cleanses the nasal cavity removing allergens and particulates that cause inflammation and congestion; its special formula shields nasal mucosa from viruses; it soothes and moisturizes irritated mucosa; its unique buffering system neutralizes inhaled irritants such as oxidative free radicals and endogenous cytotoxins which cause inflammation and damage to the sensitive mucosa and muco-cillary hairs in the nasal cavity; it enhances mucous clearance and flow by reducing mucus viscosity; its superior safety profile gives it broader application than corticosteroids and decongestants and can be used safely in children 6 months of age and adults, even with co-morbidities such as diabetes, hypertension, suppressed immune systems and pregnant and nursing females; and its exceptional safety profile allows for flexible dosing. In addition, it will inhibit and even destroy the causes of such ailments as rhinitis and sinusitis, unlike other non-drug treatments that only affects symptoms.

Choice may include one or more of these or as otherwise set forth in the above tables, as well as Table 3, below.

[0074] While various ranges of water, salt and carbon dioxide, and optional additives are shown in Tables 1 and 2, it must be noted that carbonic acid is also included at equilibrium values with the dissolved carbon dioxide, and is thus less than 0.1%. Also, to create additional examples, all of the above formulations with the equilibrium carbonic acid amounts are repeated and an additional 0.2% of carbonic acid is added to create additional, lower pH sample examples. It should be further noted that all formulations in the Tables and stated herein are merely exemplary and not intended as limiting. For example, supersaturated carbon dioxide in saline could be included in the above and the percentage of carbon dioxide would be greater than as shown. Likewise, different salt concentrations could be used. Also, while the preferred salt is sodium chloride, other nasal cavity-acceptable and functional salts may partially or fully replace the sodium chloride. Further, active additives could be significantly higher in content, such as analgesics or vitamins that have optimal efficacy at 5% could be included, wherein water/salt content would be reduced accordingly.

[0075] In the present invention dosage of the saline and carbon dioxide and carbonic acid, with or without at least one additional active component, the carbon dioxide therein does not exceed 1.0% by weight based on the entire weight of the dosage. In some embodiments of the present invention treatment, the carbon dioxide therein is in the range of 0.1% to 1.0% by weight based on the entire weight of the dosage. In some preferred embodiments of the present invention, the carbon dioxide therein is in the range of 0.2% to 0.8% by weight based on the entire weight of the dosage. In some more preferred embodiments, the carbon dioxide therein is in the range of 0.2% to 0.6% by weight based on the entire weight of the dosage. In most cases, when one or more additional actives are added, the water content is reduced by the additional weight of the one or more active additives. However, any combination of all constituents within the above and below stated ranges may be used, with the balance being water (and/or sea water).

[0076] The above Table 3 illustrates numerous active additives that may be included in the saline/carbon dioxide solutions of the present invention. Many specifics can now be realized from Table 3 without enumerating thousands upon thousands of potential additives.

[0077] Referring now in detail to the drawings wherein like reference numerals designate corresponding parts throughout the several views, various embodiments of the present invention are shown.

[0078] FIG. 1 is a block diagram of an embodiment of the present invention device and carbon dioxide, carbonic acid and saline nasal delivery methods and treatments. FIG. 1 illustrates a therapeutic non-inhaled dosage 1 containing saline fluid 3, a gas containing carbon dioxide 5 and carbonic acid 6. The saline fluid 3 contains water and at least one salt. In some preferred embodiments of the present invention, the salt is sodium chloride. In other embodiments of the present invention, other salts may be used, but it is important that any salt used in the saline fluid 3 must be safe for intranasal use. In some preferred embodiments of the present invention, the concentration of salt in the saline fluid is approximately isotonic with the salt concentration of bodily fluids. In other preferred embodiments, the concentration of salt in the saline fluid is less than the concentration of salt in bodily fluids, i.e., is hypotonic (less than human bodily fluid salt content). In still other preferred embodiments, the concentration of salt in the saline fluid is hypertonic, meaning that it has a salt concentration higher than that of bodily fluids. In still other preferred embodiments, the saline solution is saturated with salt.

[0079] The gas 5 contains some portion of carbon dioxide, and is preferably all carbon dioxide into the saline, but dissolves in the saline and also carbonic acid 6 is formed in situ. Additional carbonic acid may optionally be added to lower pH further. Human tolerable acid pH levels are desirable and may range in the area of 3.5 to 4.6. When the gas 5 containing carbon dioxide is added to the saline fluid 3, the saline fluid 3 becomes carbonated. If the therapeutic non-inhaled dosage 1 containing saline fluid 3, the gas 5 that is now dissolved, and the carbonic acid 6, is kept under pressure, the pressure can later be released (for example by opening a valve, e.g., by pushing or pressing), which causes some of the carbon dioxide to bubble out with the solution for a well dispersed mixture of the gas and liquid. This sudden release of carbon dioxide in the saline creates effervescence in the therapeutic non-inhaled dosage.

[0080] The therapeutic non-inhaled dosage travels through a flow-regulating device 7. In preferred embodiments, the flow-regulating device 7 controls the flow rate 9 of the therapeutic non-inhaled dosage 1 at a rate that is safe and comfortable for the patient. In the embodiment shown in FIG. 1, the flow rate 9 of the therapeutic non-inhaled dosage that contains the combined saline fluid, dissolved carbon dioxide, carbonic acid and optional at least one additional active component 12 (through an exit flow channel) does not exceed 5 cubic centimeter per second (cc/sec) and the carbon dioxide therein does not exceed 1.0% by weight based on the entire weight of the dosage. In some preferred embodiments, this flow rate is in the range of 0.2 cc per second to 5.0 cc per second for the combined saline fluid, dissolved gas carbon dioxide, carbonic acid and optional at least one additional active component, and the carbon dioxide therein is in the range of 0.1% to 1.0% by weight based on the entire weight of the dosage. More preferably, in some embodiments, this flow rate is in the range of 0.4 cc per second to 4.0 cc per second for the combined saline fluid, dissolved gas carbon dioxide, carbonic acid and optional at least one additional active component and the carbon dioxide therein is in the range of 0.2% to 0.8% by weight based on the entire weight of the dosage. Most preferably, in some preferred embodiments, this flow rate is in the range of 0.4 cc per second to 2 cc per second for the combined saline fluid, dissolved gas carbon dioxide, carbonic acid and optional at least one additional active component and the carbon dioxide therein is in the range of 0.2% to 0.6% by weight based on the entire weight of the dosage. Excellent results have been obtained with present invention overall flow rates of about ½ to 1 cc/sec, and carbon dioxide flowing based on percentages such as shown above and as in Tables 1 and 2 above.

[0081] Note that FIG. 1 also clearly shows optional additional active additives, block 12, and may be any, in any combination as described elsewhere herein.

[0082] The therapeutic non-inhaled dosage 1 has a flow duration 11. The flow duration 11 is the length of time during which the therapeutic non-inhaled dosage flows through the flow regulating device into at least one nasal cavity 13 of a patient. In the embodiment shown in FIG. 1, the flow duration 11 is shown as lasting between ½ and 10 seconds. In preferred embodiments of the present invention, the flow duration is adjustable to any value based on the time the user depresses or pushes on the valve activator or other release mechanism. Excellent results have been obtained with single shots and multiple shots to the nasal cavity of % to 3 seconds.

[0083] After the therapeutic non-inhaled dosage 1 leaves the flow regulating device 7, it enters at least one nasal cavity 13 of a patient. The therapeutic non-inhaled dosage 1 is adsorbed by the nasal tissue and subsequently absorbed by the body. This adsorption and subsequent absorption can have a beneficial effect on many head ailments, some of which are shown in FIG. 2. The effervescent effect of the gas 5 containing carbon dioxide causes better contact between the salt and carbonic acid in the saline solution 3 and the nasal tissue. There appears to be multiple synergistic benefits; the gas helps in the creation of more of a mist than when there is no gas, distribution is broader and gentler; the transport phenomena are enhanced—the gas holds the liquid up and there is less dripping, likewise, the gas increases the surface area of the liquid, and the liquid holds the gas in place in the nasal cavity.

[0084] The additional step 15 of instructing the patient to refrain from inhaling is for maximum delivery of the dosage to the desired nasal cavity area. While this also protects the patient from accidently inhaling the therapeutic non-inhaled dosage 1 into the wrong organ—the lungs, usage of the present invention devices and methods while inhaling or sniffing is acceptable, but not preferred for optimum results. In the prior art systems using pure gases for long duration repeated doses, it is more important to refrain from inhaling 100% carbon dioxide to prevent minor carbon dioxide poisoning (hypercapnia). Even mild hypercapnia can cause uncomfortable mental and physical effects.

[0085] In the present invention solutions, when the concentration of salt in the saline solution 3 is greater than isotonic (particularly if salts other than sodium chloride are used), it is desirable to limit the patient's exposure to the salts. The step 15 of instructing the patient not to breathe accomplishes these goals. However, it has been observed in actual usage when the breathe is not held, no harmful effects were apparent, but it is then supposed that the benefits to the nasal cavity of some of the dosage (that is passed to the lungs) is lost.

[0086] Turning now to FIG. 2, a block diagram, block 20, shows some of the medical conditions that can be treated using the present invention device with carbon dioxide and saline nasal delivery methods and treatments. In some embodiments of the present invention, the carbon dioxide and saline nasal delivery methods and treatments treat rhinitis 17, a swelling of some internal parts of the nose. In other embodiments, the present invention treats allergic rhinitis 19. In still other embodiments, the present invention treats conjunctivitis 21, an inflammation of the conjunctiva also known as pink-eye. In still other embodiments of the present invention, the common cold 23 is treated. In other embodiments of the present invention, sinusitis 25, an inflammation of the sinuses, is treated. In yet other embodiments, the present invention is used to treat headaches 27. It is important to recognize that in some embodiments of the present invention carbon dioxide and saline nasal delivery methods and treatments, multiple conditions can be treated simultaneously. For example, a patient may be suffering from both sinusitis and headache simultaneously; the present invention can alleviate both conditions at the same time. The present invention can treat any ailment shown in FIG. 2 or any combination of those ailments. It should also be recognized that the present invention may be useful in treating other ailments, particularly head ailments. The treatment of other ailments on which the present invention carbon dioxide and saline nasal delivery methods and treatments is effective are considered to be within the scope of the invention. This is especially true with respect to those dosages of the present invention that further include additional active components wherein the components have their own health benefits, and, as such are used to treat their targeted ailments.

[0087] Turning now to FIG. 3, a block diagram, block 30, shows the durations of therapeutic non-inhaled dosage used in some embodiments of the present invention carbon dioxide and saline nasal delivery methods and treatments. The durations listed in FIG. 3 are ranges, so the actual duration can be any value between the low end of the range and the high end of the range, inclusive. In some embodiments of the present invention, the duration 29 lasts between 0.5 and 10 seconds. In other embodiments of the present invention, the duration 31 lasts between 0.5 and 4 seconds. In still other embodiments of the present invention, the duration 33 lasts between 1 and 4 seconds. Durations of more than 10 seconds are also considered to be within the scope of the invention.

[0088] Turning now to FIG. 4, another embodiment of the present invention device carbon dioxide and saline nasal delivery methods and treatments is shown. FIG. 4 is a block diagram of an embodiment of the present invention carbon dioxide, carbonic acid and saline nasal delivery methods and treatments that incorporates many aspects shown in FIG. 1, and identical blocks are identically numbered. FIG. 4 illustrates a therapeutic non-inhaled dosage 1 containing saline fluid 3, a CO.sub.2 gas 5 and carbonic acid 6. The saline fluid 3 contains water and at least one salt. In some preferred embodiments of the present invention, the salt is sodium chloride. In other embodiments of the present invention, other salts may be used, but it is important that any salt used in the saline fluid 3 must be safe for intranasal use. In some preferred embodiments of the present invention, the concentration of salt in the saline fluid is approximately isotonic with the salt concentration of bodily fluids. In other preferred embodiments, the concentration of salt in the saline fluid is less than the concentration of salt in bodily fluids. In still other preferred embodiments, the concentration of salt in the saline fluid is hypertonic, meaning that it has a salt concentration higher than that of bodily fluids. In still other preferred embodiments, the saline solution is saturated with salt.

[0089] The gas 5 contains some portion of carbon dioxide. When the gas 5 containing carbon dioxide is added to the saline fluid 3, the saline fluid 3 becomes carbonated and, as well, in situ formation of carbonic acid in an equilibrium amount, is formed. If the therapeutic non-inhaled dosage 1 containing saline fluid 3, carbonic acid 6 and the gas 5 is kept under pressure, the pressure can later be released (for example by opening a valve), which causes some of the carbon dioxide to bubble out of the solution. This sudden release of carbon dioxide creates effervescence in the therapeutic non-inhaled dosage.

[0090] The therapeutic non-inhaled dosage travels through a flow-regulating device 7. In preferred embodiments, the flow-regulating device 7 controls the flow rate 9 of the therapeutic non-inhaled dosage 1 at a rate that is safe and comfortable for the patient. In the embodiment shown in FIG. 1, the flow rate 9 of the therapeutic non-inhaled dosage does not exceed the specified upper limit for both the total content (all) and there is a specified limit for the carbon dioxide (based on wt.).

[0091] The therapeutic non-inhaled dosage 1 has a flow duration 11. The flow duration 11 is the length of time during which the therapeutic non-inhaled dosage flows through the flow regulating device into at least one nasal cavity 13 of a patient. In the embodiment shown in FIG. 1, the flow duration 11 is shown as lasting between 0.5 and 10 seconds. In preferred embodiments of the present invention, the flow duration is adjustable to any value between those two range ends.

[0092] After the therapeutic non-inhaled dosage 1 leaves the flow regulating device 7, it enters at least one nasal cavity 13 of a patient. The therapeutic non-inhaled dosage 1 is adsorbed by the nasal tissue. This adsorption can have a beneficial effect on many head ailments, some of which are shown in FIG. 2. The effervescent effect of the gas 5 containing carbon dioxide causes better contact between the salt in the saline solution 3, the carbonic acid 6 therein, and the nasal tissue.

[0093] The additional step 15 of instructing the patient to refrain from inhaling protects the patient from accidently inhaling the therapeutic non-inhaled dosage 1, but is not essential and breathing may occur during use. In the embodiment shown in FIG. 4, after the therapeutic non-inhaled dosage 1 passes through the flow regulating device 7 and into the at least one nasal cavity 13 of a patient, the dose is repeated 35. In some preferred embodiments, the dose is repeated 35 between one and ten times. In still other embodiments, the dose is repeated more than ten times. The step 35 of repeating the dose can be used if a single application of the therapeutic non-inhaled dosage 1 is insufficient to alleviate the head ailment or ailments from which the patient suffers. Because the present invention has numerous applications including, but not limited to, daily cleansing, event cleansing, cold treatments, allergy treatments, etc., the number of repeat dosing may also depend on the intended purpose. For example, if daily cleansing is intended, only a single dose is usually sufficient. On the other hand, if a patient with extreme allergies has just come in from a romp in the fields or a baseball game in the springtime when pollen and other allergens are in full force, multiple dosing is recommended for more effective relief.

[0094] Turning now to FIG. 5, a block diagram, block 50, shows flow rates used in some embodiments of the present invention device carbon dioxide, carbonic acid and saline nasal delivery methods and treatments. The flow rates used in FIG. 5 are shown as ranges, and the actual rate of the flow may any value between the low end of the range and the high end of the range, inclusive. In this Figure, these rates are for saline, carbonic acid and carbon dioxide, as well as the embodiments that include one or more other actives. The rates are the same as those elaborated upon supra.

[0095] Turning now to FIG. 6, a block diagram, block 60, shows levels of carbon dioxide in the gases used in some embodiments of the present invention devices. The levels of carbon dioxide are expressed as a percentage of the gas (3 in FIGS. 1 and 4) used in the therapeutic non-inhaled dosage (1 in FIGS. 1 and 4). In some embodiments of the present invention carbon dioxide and saline nasal delivery methods and treatments, the amount of carbon dioxide 47 in the gas is at least 50%. In other embodiments, the amount of carbon dioxide 49 in the gas is at least 70%. In still other embodiments, the amount of carbon dioxide 51 in the gas is at least 95%. In other preferred embodiments, the amount of carbon dioxide 53 in the gas is substantially 100%. Gases with a percent composition of less than 50% carbon dioxide are also considered to be within the scope of the invention. Although 100% carbon dioxide is preferred, when less than 100% carbon dioxide is used, the other gas or gases may be nitrogen, oxygen, or otherwise. Nitrogen is preferred.

[0096] FIG. 7 illustrates a block diagram showing nasal treatment delivery devices that may be used in the present invention methods. Here, block 71 illustrates the caption of the Figure, namely, nasal treatment delivery device. The present invention device 71 may be a single dose dispenser (monodose) with a pressure control valve for flow rate regulation. The rate of flow is set in accordance with the ranges set forth above. In the case of a monodose dispenser, the entire dose is dispensed, so that time of dispensing does not need to be controlled—it is just the controlled flow rate over time it takes to unload the dose. Thus, a monodose dispenser may controllably release a pressurized mixture of the carbon dioxide and the saline with or without the addition of actives, until it stops flowing. On the other hand, a plural or multidose dispenser may be used, and needs dispensing on/off control such as a spring return push mechanism/valve, otherwise the entire contents could be unnecessarily released in one shot.

[0097] The various types of mechanisms for driving the contents from the container to the nasal cavity are represented as driver 75 and block 77 provides specific examples. These include squeeze mechanisms where the squeeze component or bulb is below the content so that external squeeze pressure forces out the content, much like a turkey baster; squeeze mechanisms where the squeeze component is the actual dose holding aspect of the container, like a nasal decongestant squeeze spray container; push mechanisms that physically operate much like syringes but may have more complex internal aspects, such as piercers or counter-biased valving; and others, referring to any known controlled flow mechanism available to the artisan, e.g., a pressurized container with a push release mechanism.

[0098] In FIG. 7, block 73 shows the main housing and dosage. It contains a dosage of saline fluid, carbonic acid and carbon dioxide, with or without other actives, according to parameters as more specifically set forth above. Block 79 shows that the main housing 73 may have two open ends or one open end. In the case of one open end, the top end would include the release control and dispenser head mechanisms, with a closed bottom. In the case of a main housing with two open ends, one end would have the release control and dispenser head mechanisms and the other end would contain a moveable drive mechanism such as a pressure release mechanism, a piercer or a plunger (drive piston). Block 81 shows that the main housing 73 may be at least partially flexible or it may be inflexible. If the driver is the squeezing of the main housing, it must be flexible. If the driver a moveable component attached to the main housing 71 (a push or squeeze mechanism), then the main housing 71 is preferably inflexible.

[0099] Block 83 shows the dosage release control component. Block 85 illustrates the options for the dosage release control component, which are: frangible, puncturable, one-way valve, or gate. Block 87 shows the dosage dispenser head, which Block 89 then shows the options for, which are: perforated, hard, soft, or delivery cover (sponge, foam, cotton batting, or other). Block 74 shows the optional nose guard flange for the nasal treatment delivery device 71.

[0100] FIG. 8 illustrates a front partially cut view of one embodiment of a present invention nasal treatment delivery device 90. It includes a main housing 91 with a top 93 having a hollow central area containing a dosage of the present invention medicine. This storage area may be the inside of the main housing, or it may be one or more subunits—compartments, capsules, tanks, pouches, etc, within the main housing.

[0101] In this embodiment, the main housing 91 has attached to its distal end a dosage control component that is a spray release nozzle 95 that is set for prescribed flow rates within the ranges set forth in the present invention claims and as described above. Internal bag container 105 contains the liquid/gas mixture of the present invention and external pressure on bag 105 is created by pressurized gas located in space 107 inside main housing 91. At top 93 is a dosage dispenser head, in this case, a push dispenser mechanism 97 that includes release orifice 101, actuation tube 99 and push pad 103. A user inserts push dispenser mechanism 97 into a nasal cavity at its distal end (orifice 101) while holding nasal treatment delivery device 90 and then pressing push pad 103 to release the contents. The flow regulation is set to an acceptable range so as to be relatively gentle to the user. This may include ranges in the order of 1 cc/sec to 10 cc per second. Typically this is a multidose device wherein the user is given instructions to dispense for a specified time period while not breathing, e.g., three seconds at full depression per nostril twice a day as needed. Alternatively, a built-in timer could automatically control the dose. For example, the device could have a slow spring closure that would require reset and re-push to reactivate.

[0102] FIG. 9 shows an alternative nasal treatment delivery device 110. This is an insert and squeeze device that includes a main body 111 with flexible walls and a dispensing nozzle 115 at its top 113. There is a stop 117 and threads 109 and a tapered dispensing tip 119 designed for nasal cavity insertion. There is a flow control valve 112 that regulates the rate of delivery. Additional valving, such as a duck bill valve, may also be included. The present invention liquid/gas mixture is contained within the main housing 111 and is dispensed by a user inserting and squeezing while holding his/her breath.

[0103] FIG. 10 shows a front partially cut view of a present invention nasal treatment delivery device 120 being held in a hand using two fingers and a thumb, as shown. There is a main housing 121 and a vertically moveable piston 131. A rigid, semi-flexible or flexible container or pouch 123 contains the liquid/gas mixture of the present invention and piercing tube 125 is connected to flow control valve 127. A user holds nasal treatment delivery device 120 as shown, inserts it into a nasal cavity, and while not breathing, pushes piston 131 upwardly to force pouch 123 to rupture via piercing tube 125 for medicine release through valve 127 to the nasal cavity walls.

[0104] FIGS. 11, 12 and 13 illustrate front partially cut views of one embodiment of a present invention nasal treatment delivery device 150 with a frangible internal medicine capsule 171 containing medicine 175—the gas and liquid mixtures described above. Device 150 may be used for a monodose or multidose using replacement capsules. The three Figures show the device in different stages of use. Identical number is used for all three of the figures and the device 150 is described collectively for all of these figures.

[0105] Device 150 is a push device that relies upon a frangible capsule 171 to deliver the medicine 175 by breaking open the top 173 of the frangible capsule 171. Device 105 includes a main housing 151 designed with both an open top and an open bottom, as shown. Permanently inserted into the open top of main housing 151 is a dosage dispensing head 161, with release tube 165 and control valve 153. Dosage dispensing head 161 has a downward hemispherical end 163 for puncturing the top 173 (e.g., a foil top) of capsule 171. A circular platform or dual protrusions, such as platform 167, serves as a finger grip and is attached to main housing 151. Capsule 171 may be permanently installed in main housing 151, or it may be removably placed therein so that subsequent capsules may be inserted, the former being a monodose and the latter being a multidose device.

[0106] Further, capsule 171 may be fully frangible, but is preferably so only at its top 173. Capsule 171 could have different shape, such as a hemispherical bottom to correspond to the shape of the end 163 of the dosage dispensing head 161. Or both could have other shapes and be the same or different, e.g., a chisel shaped end/bottom. Plunger 157 has a sealed piston 159 at its distal end and a widened finger rest at its proximal end. Plunger 157 may be inserted at its distal end permanently or removably, and its piston 159 may be any shape, but is preferably the same or similar to the bottom of the capsule. The piston 159 is used to drive the capsule 171 into breaker end 163, as shown sequentially in FIGS. 11, 12 and 13. In FIG. 11, a user's thumb and first two fingers are shown embracing the plunger 157 and the platform 167, respectively. By placing the device 150 in a desired nasal cavity and pushing plunger 157 upwardly while holding the device steady, and while the user holds his/her breathe, the frangible top 173 is broken and the gas/liquid medicine begins release from the device 150 (FIG. 12). The medicine is nearly fully expended by the time the plunger 157 is pushed maximally and the top 163 is near or at the bottom of the capsule 171 (FIG. 13), to deliver the medicine to the user effectively.

[0107] FIGS. 14 and 15 show alternative types of dosage dispenser heads that may be used in present invention device one has multiple release ports and the other has multiple release ports with a soft contact sheath. FIG. 14 shows a cut front view of one dosage dispenser head 180 that may be used in conjunction with a present invention device. It includes a control valve 181 to regulate release of medicine to be within the proscribed ranges set forth above. Upstream from control valve 181 is a main flow channel 183 with branches 185, 187, 189, 191,193 and 195 to show a diverse multiport manifold head for diverse. This dosage dispensing head will direct the gas/liquid medicine in many directions simultaneously to more evenly and quickly coat the sinus cavity wall.

[0108] FIG. 15 shows a similar present invention dosage dispensing head 200, but with a soft pad for nasal wall comfort. This pad does not cover the ports and may be made of soft pervious or impervious materials such as various foams or skins. Alternatively, they may be previous and cover the parts so as to create wetting foams or sponges to effect broad based medicine placement in the nasal cavity.

[0109] The ratio of carbon dioxide to salt may be any therapeutic amount. However, typically carbon dioxide saturated saline or close to saturation may be used. Alternatively, levels of carbon dioxide may be below saturation or supersaturated, as mentioned, and the levels of actives added to the solution are a matter of choice. In preferred preparation methods, the additive(s) are added to the saline and then the carbon dioxide is injected or otherwise added. Alternatively, the additives may be already in the solution and others may optionally be added, such as sea water with natural additives to which vitamins are further added.

[0110] In order to show the unexpected results of the present invention saline/carbon dioxide/carbonic acid (with or without additional active additives), consumer testing was conducted and very effective results were achieved. More than 85% in one set of testing and more than 90% in another favored the product. Only one testing consumer experienced slight stinging and no one experienced severe stinging as had occurred with carbon dioxide gas treatments as proscribed by the Capnia prior art to Rasor et al cited above. Additionally, biofilm testing was conducted to test the efficacy of the present invention.

[0111] FIG. 16 shows comparative graph bars for present invention sparkling saline products A, B, C, D and E, and for a reference product (conventional prior art saline without the carbon dioxide and carbonic acid of the present invention). The tests were performed by an independent testing lab and consistent biofilms (normalized to match) of staph bacteria (24 hour growth s. aureus biofilm) Identical spays of present invention products A through E and the Reference Prior Art saline (0.9% isotonic) were used in the experiment. The solid bars represent relative populations of the bacteria one half hour after treatment, and the dotted diamond bars represent relative populations of the bacteria after one hour. As can be seen, all of the present invention products A through E continued to kill or remove the bacterial threat after one hour and reduced bacterial population after one half hour and after one hour significantly as compared to the end bars (biofilm control, untreated). Further, using the Prior Art Saline, the population of bacteria rose significantly after one hour as compared to one half hour. Thus, saline does not appear to have any continuing efficacy after its mechanical cleansing, whereas the present invention products were still maintaining or lowering the low population of bacteria. In addition, color photographs of these samples showed significant browning of the otherwise live green colored bacteria, further supporting that the bacteria was not only removed by the present invention, but also partially destroyed biologically. These results are even more surprising; the present invention CO.sub.2 levels are much lower than the proscribed prior art Rasor et al indicated levels of CO.sub.2, yet significant efficacy has been achieved, as evidenced by both the consumer use testing and the laboratory testing.

[0112] Although particular embodiments of the invention have been described in detail herein with reference to the accompanying drawings, it is to be understood that the invention is not limited to those particular embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims. For example, the term “additives” as used herein means any active component that exists with the saline other than the salt and the water. Thus, active additives refer to additional active components that are inherent or are added during preparation and have an additional function. For example, a solution from a natural spa would have micronutrients in addition to the salt and water. As another example, sea water may be purified and selectively reconstituted to have controlled levels of salt, as well as other natural additives, such as beneficial minerals and metals. Further, while the delivery devices described herein are shown for nasal passage delivery, these same devices with the same contents claimed could be otherwise used, for example, to clean ears or other bodily cavities, to rinse mouths, or even to flush and/or treat wounds.
