DETAILED DESCRIPTION OF THE INVENTION

[0039] In a medical situation whether in military operation or emergency events, there are situations where rescue breathing must be provided to an unconscious patient who requires an airway to maintain oxygen to the lungs. In most instances today, a breathing bag, such as those by AMBU, is frequently utilized, which can be held on the patient and compressed to force air into the lungs. The bag is directly attached to an endotracheal tube, and once the tube is inserted, the bag is compressed. After the patient's lungs are filled with air through the compression of the bag, the lungs, due to the weight of the cavity, decompress the forced air, and exhale the air, thus completing a single breath. After compression, the bag reinflates, and the process can be repeated. Subsequently, another compression may proceed, to again force a breath into the patient.

[0040] However, performing this procedure requires that at least one hand from rescue personnel is placed onto the bag to perform these compressions. In some instances, two hands would be required to properly compress the bag and to give sufficient breath to a patient. The loss of a hand, or hands is problematic in both military instances as well as in nonmilitary emergency situations.

[0041] Indeed, as described herein is a rescue tube comprising components and features that allow for a user to maintain the use of their hands for other tasks, while providing rescue breathing to a patient. For example, breathing may be maintained, while the rescuer treats other wounds. In military situations, the rescuer may need hands to maintain a weapon or to remove both the rescuer and the injured from the battlefield as urgently as possible, and thus having free hands to maneuver or manipulate additional devices is necessary. For example, the rescuer can use both hands to lift and carry the injured away from the battlefield.

[0042] The rescue tube functions as an extension between the provider and the patient. However, the patient must first have a breathing tube inserted. Examples of breathing tubes include endotracheal tubes, as well as mouth insertion devices, for example, comprising cuffs to enter the trachea. Examples including the King Airway and Combitube, though other brands and examples exist. In general, these devices are airway adjuncts, devices that can be placed into reach the trachea to provide oxygen. For mouth placed devices, these often include a balloon or cuff that blocks the esophagus to allow air to enter the trachea, to fill the lung.

[0043] The embodiments of the invention described herein, provide a novel device, a rescue tube, to connect to one or more breathing devices. For example, as depicted in FIG. 1, a rescue tube (1) is depicted. The rescue tube (1) comprises a length of tubing (2), said tubing have a proximal opening to the patient (patient end) (22) and a distal opening (rescue end) (21) and each of the proximal (22) and distal (21) ends providing passage of gas through the tube. In certain embodiments, the tube is a corrugated flexible polyurethane tubing having an outer diameter of about 5 to about 50 mm, with an inner diameter of about 4 to about 45 mm. Preferably the tube has an outer diameter of about 10-30 mm, with an inner diameter of about 9-28 mm. Most preferably, the tube is between about 10 and 22 mm, and each of the proximal (22) and distal ends (21) capable of receiving a second component. In certain embodiments, the tubing can be any flexible tubing that allows for the passage of gasses between the two ends.

[0044] Preferably, the second component to be received into the proximal (22) end of the tube (2) is an adaptor (10). For example, in the proximal (22) end of FIG. 1, an adaptor (10) is provided engaged into the proximal end (22), thus providing a new component for attaching additional parts. The adaptor (10) is depicted in FIG. 7 in detail, having a first adaptor end (11) and a second adaptor end (13), and a central connector junction (14) having a raised edge. The adaptor (10) is defined to have an outer diameter on the first end (11) and second end (13) to fit into the proximal end (22) of the tube. Accordingly, the adaptor is mated to have a corresponding outer diameter that mates with the inner diameter of the proximal end (22) of the tube. The proximal end (22) of the tube then mates onto the first end (11) as far as the central connector junction (14). The first end (11) and second end (13) of the adaptor are connected via a passage between each of the first end (11) and second end (13), thus the adaptor functions as an extension of the tube (2) allowing for passage of gasses through the adaptor (10).

[0045] The first end (11) and second end (13) of the adaptor are defined to be received into the proximal end (22) of the tube, on one end, and then to have a suitable outer or inner diameter to mate with the flow side opening (16) of the one-way valve (12). Accordingly, the adaptor (10) functions as one of ordinary skill in the art would expect it to function, it allows for connection of the proximal end of the tube (22) to the flow side opening (16) of the one-way valve. Those of skill in the art will recognize that the adaptor (10) is necessary only so far as the proximal end of the tube (22) requires such adaptor (10) to mate with the flow side opening (16) of the one-way valve. An appropriate tube diameter and corresponding diameter (or attachment means, for example those used by Luer-Lock or other known attachment means), would allow for exclusion of the adaptor (10).

[0046] The one-way valve (12) functions to allow air to only flow through from the flow side opening (16) through the one-way valve internal valve (19) and through to the one-way valve check side. As those of ordinary skill in the art recognize, the one-way valve allows air flow only from the flow side (16) through to the check side (17). If air is pressed back from the check side (17), it will not pass through the internal valve (19), but will instead be released through the internal valve (19) (as a relief valve) to allow the air to exit the valve, but not proceed into the tube (2). Accordingly, this valve thus prevents passage of gasses back through this valve, and instead allows release of the exhaled gas.

[0047] The check side (17) then mates with a double swivel elbow (4). Finally, on the opposing end of the tube (2), (distal end of the tube [21]) a mouthpiece (15) is attached. FIG. 2 specifically shows the mouthpiece (15) in the partial exploded view. The mouthpiece (15) will be inserted into the distal end of the tube (21). As with the proximal end of the tube (21), an adaptor (10) may be utilized, should one be necessary to mate the tube diameter to the diameter of one end of the mouthpiece (15). For example, the adaptor (10) is depicted in FIG. 12 attaching to the distal end (21) and attaching to a bag (40). As with the proximal end (22), the adaptor (10) is utilized to connect a further component to the flexible tubing.

[0048] FIG. 3 provides an exploded view of each of the components in serial. The mouthpiece (15) connects into the distal end of the tube (21). Then the flexible length of tube (2) allows for passage of gasses from the distal end (21) through to the proximal end (22) before the proximal end (22) is inserted an adaptor (10). The adaptor (10) first end (11) mates with the proximal end (22) to an airtight seal (up to a sufficient PSI to allow for rescue breathing). However, some air passage may occur in one or more of the connections without destroying the function of the device, should each connecting not be perfectly airtight for the force of air being provided.

[0049] Into the second end (13) of the adaptor (10) is the one-way valve (12). Into the check side (17) of the one-way valve is inserted the short arm (50) end (5) of the double swivel elbow (4). Air passes through the check valve from the flow side (16) through to the check side (17) and now into the double swivel elbow (4). The long arm (51) of the double swivel elbow (4) possesses a junction (9) to allow for complete rotation of the double swivel elbow (4). Further the elbow (4) contains a self-sealing port (8). The long arm (51) of the double swivel elbow (4) further optionally possesses an accordion structure (7) to allow for further rotation and movement of the elbow (4), and ending on the long arm with a long arm opening (6).

[0050] FIG. 4 provides an embodiment of a tube (2). The tube can be any length of tubing allowing for passage of gas from the distal end (21) to the proximal end (22) and have openings at each end to either directly receive a second component, or to receive an adaptor. Typically, the openings allow an insertion into the inner diameter, or alternatively over the outer diameter of each of the proximal end (22) and distal end (21).

[0051] FIG. 5 depicts the mouthpiece (15). Mouthpiece (15) comprises an insertion end (28) and a breath giving end (27). The breath giving end (27) is typically wider than the insertion end (28) and provides a comfortable fit for placing into the mouth of a rescuer. The breath giving end (27) comprises a raised flange (29). This raised flange (29) allows for the mouthpiece breath giving end (27) to be in the mouth, and the teeth or lips to hold the mouthpiece (15) without it slipping or falling out of the mouth. The breath giving end (27) is connected to the insertion end (28) with a passage, allowing for air to flow through the mouthpiece (15), and again act as an extension of a tubular structure.

[0052] FIG. 6 provides as simple exploded view of the mouthpiece (15) insertion end (28) as it would be inserted into the distal end (21) of the tube. Conversely, on the opposing side at the proximal end (22), the adaptor (10) would be inserted into the proximal end (22).

[0053] FIG. 7, as described above, briefly, provides for an embodiment of an adaptor (10). The precise dimensions of the adaptor may be modified based on the precise inner and outer dimensions of the components to be attached. Those of skill in the art recognize that each end of the adaptor can be the same or different sizes and can attach either internally or externally to a component on each end. The adaptor (10) should be of sufficient size to allow for secure fit into each component. In some embodiments, the rescue breathing device is assembled from a kit of components, and thus a mechanical, friction fit is appropriate. It may be suitable to have a portion of the adaptor (10), to possess an O-ring or other component on each end, to function as a gasket, to aid in the airtight fit of the components.

[0054] However, the device may also be appropriately manufactured with components preattached, and this may include an adhesive suitable to attach such components. Where the rescue breathing device (1) is premanufactured, such features, like the adaptor (10) may be excluded, as the precise fit of the one-way valve (12) may be manufactured to fit into a proximal end (22) of the tube.

[0055] FIG. 8 details a one-way valve (12), having the flow side (16), the check side (17), a junction (18), and an internal valve (19). Those of skill in the art recognize that numerous designs exist for check valves. The valve must allow passage of air from the flow side (16) through the check side (17) but prevent flow of air from the check side (17) back to the flow side (16). This is so that when a patient is intubated, air can be blown or provided from the distal end (21) and flow through the one-way check valve (12), through the double swivel elbow (12) and through the endotracheal tube (23) and into the patient's lungs, but when the patient exhales, gas will not pass through the one-way valve (12). Furthermore, blood, saliva, vomit, and other bodily fluids from the mouth and stomach will not be passed through the one-way valve (12) to the rescuing person. The one-way valve allows flow in one direction from the rescuer flow side (16) to the patient (check side [17]), however during the exhalation phase the exhaled air travels to the one-way valve (12) to the internal components (19) preventing return flow to the rescuer end however there is a relief valve where the exhaled air is removed from the system allowing The patient to expire used air. This way there is room for new air to enter the lungs.

[0056] FIGS. 9A-9C detail portions of the double swivel elbow (4). The double swivel elbow (4) contains a short arm (50) and a long arm (51). On the short arm (50) is the short arm end (5) of the double swivel elbow (4). This short arm end (5) contains an outer/inner diameter sufficient to mate with the check side (17) of the one-way check valve (12). At the opposing end of the short arm (50) is a self-sealing port (8). This port can be utilized for further attachment of additional components. Indeed, the port may further accept an adapter to allow for attachment of such accessories. For example, oxygen may be attached at this point, or direct placement of other gasses for surgical procedures as nonlimiting examples. Due to the nature of the self-sealing port, a needle or other tube can be inserted and withdrawn, if such insertion is necessary to provide oxygen or other medications to the intubated patient.

[0057] The long arm (51) of the double swivel elbow (4) possesses a junction (9) to allow for complete rotation of the double swivel elbow (4). In certain embodiments, the junction (9) allows for free rotation of the short arm (50) as compared to the long arm (51). In other embodiments, the components are fixed. The long arm (51) of the double swivel elbow (4) further optionally possesses an accordion (7) to allow for further rotation and movement of the double swivel elbow (4). For example, the accordion structure (7) can allow for flexible rotation, angled orientation of the components, and provides for a component that allows for a high range of motion and flexibility to safely insert and intubate a patient, while allowing for range of motion. For example, the extension feature (52) along the longitudinal axis of the long arm (51) allows for extension of the double swivel elbow (4) away from the face of the patient. Alternatively, the rotation or angling of the accordion structure (7) can angle according to (53). The angle should be able to extend at least 90 degrees, and preferably up to 180 degrees, where such angle can be generated along any orientation of the accordion structure (7). The ability to angle imparts additional flexibility to the use of the tube, because it allows for secure operation of the rescue breathing tube (1) while reducing the risk of extubation of the patient. At the end of the long arm (51) is the long arm end (6), for mating to a breathing device, such as a mask, endotracheal tube, or other device for positioning in the airway of a patient.

[0058] On one portion of the short arm (50) is gas line attachment feature (30). This allows direct connection of a typical oxygen line to the double swivel elbow (4). Typically, this can be used once a patient is to a safe setting and oxygen is available to assist in treating the patient. Other gasses can be administered through this line, as known to those of skill in the art.

[0059] FIGS. 10A and 10B show each of the ends of the tube (2). For example on the proximal end (22) are merely repeated to the adaptor (10), in line with the one-way check valve (12), and then attaching to the short arm end (5) of the double swivel elbow (4). FIG. 10B, conversely, shows the distal end (21) connecting to the mouthpiece (15).

[0060] FIG. 11 details a complete rescue tube being attached to an endotracheal tube (23). Those of skill in the art will recognize that the endotracheal tube (23) functions by a small diameter tube having a soft distal end (26) and a balloon (25) near the distal end (26), which is inflated by an airline to assist in air flowing through the tube and not around the tube. Furthermore, this balloon (25) assists in maintain the positioning of the endotracheal tube. At the proximal end (24), the tube contains an opening of sufficient diameter to mate with the long arm opening (6).

[0061] FIG. 12 details a further embodiment that replaces the mouthpiece (15) with a breathing bag (40). The breathing bag (40) contains an aperture opening (41) to mate with an adaptor (10). The bag (40) contains a hand strap (42) to assist a user with holding the bag (40) and compressing it repeatedly. At the tail end of the bag (40) is an oxygen reservoir (43) that can be filled with oxygen to increase the oxygen given through the manual compressions of the bag. Here, at the distal end (21) the adaptor (10) is necessary to allow for exchange of the mouthpiece (15) to the bag (40).

[0062] In certain embodiments, the diameter of the tube (2) is such that no adapter (10) is required. Indeed, the adapter may include several different diameter adapters (10), wherein one end is of constant diameter, able to insert into the tube, while the other end has an outer diameter and an inner diameter, each of which can connect to a secondary device. Several adapters (10) can be included with a kit, each having different outer and inner diameters of the opposing end, to allow for a variety of secondary devices to be inserted therein. Certain secondary devices will fit directly into the tube (1) and thus the adapters (10) are optional for these features. The adapters (10) may further include locking or latching mechanisms, to selectively attach and detach secondary devices. For example, a breathing bag may selectively snap into place and remain securely connected, but may be optionally removed, if the breathing bag (40) is no longer needed, but connection to a different breathing apparatus would be advantageous.

[0063] Adapters are particular useful, however, to allow the tube to be a multipurpose material. Accordingly, the adapters allow for a plurality of components to be interchanged, as necessary, for the particular application of the breathing tube.

[0064] As depicted in FIG. 11, the rescue breathing device (1) allows for connection to an endotracheal tube (23), without the requirement that a breathing bag be directly attached. Indeed, the mouthpiece, being attached at the distal end (21) of the tube (2), allows for several inches, to more than a foot, separation from the patient's endotracheal tube (23) to a device that is allowing a rescuer to provide air. The mouthpiece (15) is particularly advantageous as it allows for direct breathing to be given and does not require additional elements. In tactical situations, or areas where immediate intubation is necessary, such a device can ensure that the patient is receiving oxygen while being safely removed from the situation, to receive additional care. Accordingly, the rescue breathing tube (1) can be utilized a distance away from the patient and leaves both hands for a rescuer free to work with the patient. This enables a wider range of user opportunities, than any existing technology.

[0065] Furthermore, this extra space can also be used in certain rescue situations. For example, in the situation where an injured patient is in a space constrained position, due to a building collapse, due to a car accident, a military situation, or the like, the rescue tube can be attached to a breathing tube, and inserted into in small space for rescue breathing, wherein the bag may not easily fit in that space, or cannot be angled properly to allow for attachment. Accordingly, to provide rescue breathing, a rescuer can breathe directly into the opposed end of the flexible tubing (2). Alternatively, the rescuer can breathe directly into a mouthpiece (15), which can be attached to the tube, to allow for hands free breathing to the patient. Similarly, a bag (40) can be attached at the distal end (21) of the rescue tube and allow for compression of the bag to provide the air to the patient. In each case, the rescue tube provides for both stability of the breathing tube, as well as a flexible attachment to the breathing tube to provide mouth or bag generated air to the patient.

[0066] A further benefit of the rescue tube, whether use with a mouthpiece or with an attached bag (40), is that because of the flexibility of both the accordion structure (7) and of the flexibility of the tube (2), the tube (2) itself can freely move, while maintaining the endotracheal tube (23) in a stable spot within the patient. This is in direct contrast to the normal occurrence for a bag, which can easily move the endotracheal tube (23). Of course, this is a problem as a patient may be extubated in error, forcing rescuers to stop and reinsert the breathing tube to the patient. Furthermore, the bag may not easily connect to the breathing tube, thus forcing the rescuers to manipulate the patient or have a compromised bag (i.e. mostly compressed, or poorly attached), thus resulting in shallow or weak breaths to the patient.

[0067] Therefore, the rescue tube (1) provides for several benefits that are not seen in the prior art. First the tube provides for a flexible and accordion like structure to allow for total flexibility and movement of the tube, even when connected to the breathing tube on the patient. The distal end (21) of the rescue tube can then be open, for direct breaths from a rescuer, or can be attached to a mechanical lung, or attached to a bag, for providing oxygen rich air to the patient, and forcing air into the lungs. This provides for hands free operation of the rescue breathing tube (1). Second, because of the small structure, the rescue breathing tube (1) can fit into small spaces or locations and can allow for easier attachment to an endotracheal tube (23) and therefore attached to the patient regardless of the position of the patient. Finally, the flexible nature of the device prevents unintentional removal of the breathing tube.

[0068] Another way that the rescue tube can be utilized in a hands-free manner is to attach the rescue tube to an airway adjunct and connect the opposing end to a breathing bag. Because of the flexibility and length of the rescue tube, the bag can be placed under and arm, between the body, and then compressed to provide air to the patient. The bag could also be placed between an arm or body and another accessory.

[0069] The rescue tube can therefore be utilized in a method to provide oxygen to a patient comprising, inserting an airway adjunct to said patient, attaching to said airway adjunct a rescue tube, providing air into said rescue tube to provide air to said patient.

[0070] The invention as described herein can be modified based on the knowledge of a person of ordinary skill in the art with components that form the same or similar function. Those of skill in the art will recognize such possible variations and that these variations do not take away from the embodiments of the invention as described herein.

[0071] A method of providing a rescue breath to a patient comprising: attaching a rescue tube as described herein, to an endotracheal tube inserted into said patient; breathing into a distal end (21) of the rescue tube, wherein said breathing forces air from a mouthpiece (15) through a flexible tube (2), through a one-way (12), into a double swivel elbow (4), and finally into the endotracheal tube (23).

[0072] Those of skill in the art will recognize that the components are made of medical grade materials, each of which are capable of being sterilized for use. In preferred embodiments, the materials are fitted together, either with and adhesive or friction fit, and sterilized. The sterilized device can be packaged, and then sterile components can be utilized as needed. Accordingly, these devices, after use, can then be recycled or destroyed, or alternatively resterilized for future use.

[0073] Components are also sold as a kit, allowing for the components to be assembled based on the particular needs of a user.

[0074] In preferred embodiments, the device provides for rescue breathing use, while allowing for the rescuer to maintain free hands. A method of providing rescue breathing, therefore comprises inserting an air adjunct to the patient; attaching the rescue breathing device, and imparting air through the rescue breathing device to the patient, forcing air to the patient and letting the patient exhale before providing a further and successive breaths to said patient. The air can be provided via a mouthpiece, and rescue breaths provided by breathing into the mouthpiece. Alternatively, a breathing bag, which compresses air and forces it out of one end of the bag, can also provide air. Similarly, a machine or mechanical device can provide air under sufficient pressure.
