[0086] Referring now to
[0087] The therapeutic compression apparatus 200, 300 may be comprised of a bladder 202 such as a compression bladder either integrally formed in the therapeutic compression apparatus 200, 300 or the therapeutic compression apparatus 20, 3000 is configured for the bladder to be inserted (not shown) within the therapeutic compression apparatus 200, 300. The therapeutic compression apparatus 200, 300 is configured and adapted to wrap around a patient's limb such as in for instance a leg, calf, knee, foot, ankle, thigh, torso, arm, neck or any other limbs. The therapeutic compression apparatus 200, 300 is not limited to the limbs or body parts listed above but could be any body part such as without limitation a foot, ankle, calf, lower leg, knee, thigh, groin, hip, leg, buttocks, torso, stomach, chest, shoulder, arm, elbow, hand, wrist, neck, head or the like and any combinations thereof. As shown in
[0088] In this embodiment, hook and loop fasteners 224 are provided along the edge of inner and outer sheets in order to ease adjustment and secure lower leg therapeutic compression apparatus 200 on a patient's limb such as for example a calf or foot. It is envisioned that the thigh therapeutic compression apparatus 300 can includes hook and loop fasteners 324 but also could be secured to a patient's thigh by other means, such as zippered, buttoned, or be cuff shaped by other such suitable means. Further, it is also envisioned that hook and loop closures 224, 324 can be replaced by material similar to that of an ankle strap, knee strap, hip strap or any other type of strap (including those described below) and be welded/sewn/attached to bladder for improved comfort.
[0089] Referring now to
[0090] It can be appreciated that depending on the location of the therapeutic compression apparatus 200, different pressure gradients may be utilized. Other possible gradient pressure profiles may be imagined based upon the geometric location of the spot welds 214, alone or in connection with the linear welds 216. For example, in the thigh therapeutic compression apparatus 300, depending on the location of the limb to be compressed, such as the medial area of the thigh, the linear welds 316 and spot welds 314 may be in different geometric configurations than those shown in
[0091] It can be appreciated that depending on the location of the therapeutic compression apparatus being placed on the patient's body part or limb, different pressure gradients may be utilized. Further, different pressure gradients may be employed depending on the treatment (general swelling, lactic acid build up, lymphedema, post-sclerotherapy, CVT, DVT, etc.) and the treatment site. Other examples of bladder pressure gradient profiles are described in U.S. patent application Ser. No. 12/911,563 and U.S. patent application Ser. No. 12/855,185, the disclosures of which are incorporated by reference in their entirety.
[0092] In this embodiment as shown in
[0093] Referring now to
[0094] In this embodiment, the retaining means 180 is a belt or strap and includes a belt snap 181A (male connector) and a belt clip 181B (female connector), which are joined together by the belt strap 181B being inserted within the belt clip 181A and then snapped together. Other embodiments not shown may include a garter belt system or a belt buckle or any other known closing or connecting means. Again, the retaining means 180 if a belt may be closed or connected though other connecting means such as for example and not limited to hook and loop closure or VELCRO™ or any other known connecting means such as buckles, straps, buttons, snaps, zippers, hooks and other combinations. As shown in
[0095] It will be appreciated that the chambers of the bladder 202 may be filled by air, fluid or other known means of inflation, It will also be appreciated that the bladder 202 can be arranged to receive air and be inflated using a manual pumping bulb (as shown in
[0096] As shown in
[0097] The inflation means 150 shown in this embodiment in
[0098] As shown in
[0099] An optional protective cover, shown in
[0100] Once the therapeutic compression apparatus 200 is secured around a patient's limb such as for instance a leg, bladder 202 is not able to shift out of place, thus increasing comfort and reducing fitting issues on the patient. In order to increase the ease of ambulation by a patient, in an exemplary embodiment, the inflation means 150 is connected to the bladder 202 via the male luer slip 161, and the inflation means 150 is connected to a retaining means 180, which in this embodiment is a belt. The user can then activate the main pump 156 via the ON-OFF switch 165. The user then wears the inflation means 150 similar to a mobile phone on an individual's belt. In this embodiment, the retaining means 180 is a belt which is adjustable to the waist of the user via an adjusting means 182 such as for example only a triglide and/or end clip. The user thus has increased mobility compared to a therapeutic compression apparatus where the inflation means is integral to the apparatus.
[0101] The inflation means or mechanism for each of the various embodiments of the present invention may include a hand pump, electric pump, battery-operated pump, remote controlled pump, air pump, gas pump, or any other known inflation means. A number or variety of inflation means can be employed such as a manual pump, hand pump, foot pump, mechanical pump, electrical pump, battery-operated pump, static pump, intermittent pump, varying pump, automatic pump, pneumatic pump, negative pressure pump, suction pump or vacuum, pulsing pump, or any other known or developed source of inflation so as to provide a certain pressure within the bladder so to provide compression in use by the patient. Further, the inflation means could include a means to monitor or regulate the inflation. The inflation means could include programming such that the bladder 202 is inflated and deflated to a set pressure at intervals or at set times throughout the day or night when the compression apparatus is in use worn on the patient. For instance, by way of example only, the inflation means could be set to 40 mm-Hg at 9 am and then set to deflate to 20 mm-Hg at 11 am and then set to inflate to 30 mm-Hg at 12 pm and so on throughout the day and night for each patient individually. In another embodiment of the present invention, if the therapeutic compression apparatus has two separate bladders (not shown but for instance bladders 202A and 202B) then there may be two separate inflation ports 112 (e.g. 212 A and 212B not shown) that are each connected to either the same or different inflation means, and the pressure levels of the first bladder 202A and the second bladder 202B could be the same or have different pressure levels. For instance, by way of example only, the inflation means could be set to 40 mm-Hg for the first bladder 202A and set to 20 mm-Hg for the second bladder 202B, or each could vary and the inflation means be set to inflate, deflate, inflate, etc. throughout the day as described above. As shown in
[0102] As an example, treatment options would include intermittent pneumatic compression (HPIPC) 60 minutes twice daily for 16 weeks. In this example, the inflation means would have a pressure level of 120 mm-HG and the bilateral pressures of 120 mm Hg in a cycle time to provide sequential compression for 4 seconds (+/−0.5 seconds) followed by a 16-second rest period (+/−3.0 seconds), resulting in a 20-second cycle or 3 cycles per minute. This treatment may help reduce vascular issues such as lymphedema, DVT, CVI and the like.
[0103] In another example, treatment options could include reducing DVT through applying pressure pre-operation, for instance for the knee surgery, TKR, KRA, hip surgery, THR, HRA, or the like, to the target limb for a period of days or weeks or months prior to the surgical date. Prior to surgery the patient would apply compression via the therapeutic compression apparatus and inflation means of the inventive system to reduce swelling of the target limb. During the actual operation and immediately after surgery while still in the hospital setting, the patient would use the same or a different therapeutic compression apparatus connected to an inflation means within the hospital such as an intermittent compression pump accessible through the wall of the patient room or wheeled into the room, which may be considered mechanical DVT prophylaxis. Once discharged from the hospital setting, the patient can retain the same therapeutic compression apparatus and use it at home by applying pressure via the inflation means 150 of an electrical pump configured to apply both constant static pressure and intermittent varying pressure based on the treatment plan. The method of use may reduce or prevent DVT, CVI and other vascular issues. The therapeutic compression apparatus has a universal inflation port configured so it can connect to a hand pump (400) and electric pump (156) and a hospital pump (not shown) and many other pumps. This method if use of the inventive system may reduce swelling pre-surgery and post-surgery and also reduce CVU, DVT and other post-surgical complications. As stated above, the patient is more mobile and ambulatory using the inventive system including the inflation means 150 attached to the retaining means 180 belt. This system is also less cumbersome than current post-operative compression systems which weigh many pounds on their own and other products on the market.
[0104] In another embodiment method of use of the inventive system the system us used both prior to, during and after a lower body surgery. Particularly with lower leg joint replacement (knee and hip) surgery, there is an increased risk of DVT along with the pre and post-op issues related to leg swelling. Due to the universal nature of the inflation port (or valve) on the therapeutic compression apparatus, it can be coupled with a hand pump, a battery-operated pump, or the existing electrical intermittent pneumatic compression DVT systems that exist on the market. However, the sleeves to these existing DVT systems are not worn to reduce swelling, cannot apply compression in of a static nature, and cannot be used for mechanical DVT prophylaxis without the IPC DVT control unit. Thus, another method of use to improve the outcomes includes the steps of (a) at least 3 days pre-surgery, the patient is given the therapeutic compression apparatus 200 to reduce limb volume and leg swelling, which can be achieved with either static or intermittent compression pressure levels, then (b) during surgery and immediately post-operative the therapeutic compression apparatus 200 is connected to the IPC DVT control unit in the hospital or clinic or outpatient office setting, and the IPC cycles intermittently to provide standard DVT mechanical prophylaxis, and thereafter (c) as the patient is discharged, the patient is given the therapeutic compression apparatus 200 to bring home along with either or both the hand compression pump or battery operated (or electrical powered) inflation means 150, such as pump 156, to manage the risk of DVT along with preventing further swelling.
[0105] It is envisioned, that the inventive system 100 could be used in conjunction with a lower leg compression apparatus (such as those described in U.S. Pat. Nos. 9,033,906 and 7,967,766 and 7,559,908 and 7,276,037 and U.S. Ser. No. 13/444,600), and one inflation means could be connected to each of the two compression apparatus as shown in
[0106] In one embodiment of the invention, the inflation means includes a manual pump (as shown in
[0107] Further, the therapeutic compression apparatus may be deflated by a button or a switch to deflate the bladder 202 and thus release the pressure and/or compression profile. In another embodiment (not shown), the switch may have a plurality of integrated umbrella valves so that one umbrella valve is set and closed to maintain the pressure within the bladder 202, while a second umbrella valve would release a certain amount of air or fluid within the bladder 202, so as to release the pressure such as while the patient is walking (pressure increases on the thigh with each step or on the foot portion of a lower leg therapeutic compression apparatus) or flying (pressure increases based on altitude), and a third umbrella valve which would release all the air or fluid in the bladder 202, thus release all pressure and deflate the therapeutic compression apparatus 200). For instance by way of example only, the first umbrella valve is set in a closed position so that when activated this umbrella valve maintains the amount of air or fluid in the bladder 202 and thus maintains the set pressure, say for instance at 45 mm-Hg, the second umbrella valve is set to release the air or fluid within the bladder 202 if the pressure within exceeds 45 mm-Hg and bring the pressure down to 45 mm-Hg (such as when in high altitude or other increases in pressure) and then maintain the pressure at 45 mm-Hg, and a third umbrella valve is set to open and release all the air or fluid within the bladder 202 and thus release all pressure when activated by the patient so as to deflate the bladder 202 and the therapeutic compression apparatus 200. By way of another example, the dial or display 157 may include graphics such as (A) “Walk” wherein the set pressure amount is maintained while the patient walks and the pressure spikes and returns over and over in time as the umbrella valve remains in the closed position, (B) then a graphic of “Air” wherein the set pressure amount will be maintained by this umbrella vale occasionally releasing pressure as the pressure increases over the set amount or value so that the umbrella valve is activated to release air or fluid within the bladder 202 and release the pressure yet then close and stay closed to maintain the set pressure amount, and (C) “Release” or “Deflate” wherein the pressure will be released and the air or fluid within the bladder 202 released to deflate and this umbrella valve is always in the open position. In this embodiment (not shown) there are three umbrella valves with one set to always open the bladder 202 to release pressure completely, one set to always close to maintain air or fluid in the bladder 202 to maintain pressure, and a third set to open or release at a predetermined or set pressure point. In all of the embodiments referring to umbrella valve the umbrella valve may also be a switch (manual or otherwise) or a digital switch or any other known means to open, close or partial release air or fluid within a bladder and thereby maintain, change or release pressure therein.
[0108] The inventive therapeutic system 100 includes an inventive scaling means connected to the bladder 202, 302 so as to maintain the gradient compression profile and/or gradient pressure profile when the inflation means 150 is either disconnected from the therapeutic compression apparatus 200, 300 or the inflation means stops providing additional inflation or pressure. In one embodiment as shown in
[0109] The sealing means also includes a valve 290 within the inflation port 212, 312. As shown in
[0110]
[0111] The inventive system 100 may be included in a kit including a therapeutic compression apparatus 200, an inflation means 150, a retaining means 180 such as a belt, and a connecting means such as a tube 160. The inflation means 150 may require a charger depending on the source of energy, such as an electric charger (not shown) for connecting to the USI3 port 159 and the kit would include such a charger. As seen i.n
[0112] Depending on the therapeutic compression apparatus 200 in the kit, a stocking, sock 220or other layer between the patient's skins and the therapeutic compression apparatus 200 may be included. Depending on the embodiment of the inflation means 150, a flexible cover 158 may be included in the kit. Other devices or apparatus may be included in such a kit or for instance, replacement or spare connecting means such as tubes 160, spare batteries 171, spare USB cables 173 and the like The kit may also include various wound dressings and/or bandages. The wound dressings and/or bandages may be disposed of on a more frequent basis and the inventive therapeutic compression apparatus is applied in conjunction or combination with the wound dressings and/or bandages. In one embodiment the therapeutic compression apparatus is used over or on top of the wound dressing applied to the skin.
[0113] Another embodiment of the present invention includes a method of applying a measured compression amount with feedback. In this embodiment (not shown), Compression Bladder A is inflated by Inflation Source C—the nature of Compression Bladder A is such that the amount of compression is determined by the amount of inflation medium (typically air) pumped into A from C. In this design, Inflation Source C is also coupled with Bladder B, which has a fixed volume of air. When Compression Bladder A inflates, it will squeeze Bladder B as it compresses Compressed Item F. Inflation Source C is able to read the line pressure from the Coupling Line E to determine the interface pressure from Bladder B—in this design, Inflation Source C can be calibrated to provide only the amount of inflation medium necessary into Compression Bladder A as determined by matching the desired interface pressure from Bladder B. Other configurations may be employed so that feedback may be obtained from the inflation means and compression apparatus.
[0114] Another embedment of the present invention includes a Sequential Gradient Compression with Single Chamber. In such embodiment (shown as
[0115] The inflation means 150 may also include a sensor 155 to measure the air pressure being applied in the tube 160. Another embodiment of the present invention include an electric or other automated inflation means such that the bladder is inflated to a set volume or by reading the back pressure of which is being filled in. A pressure cycling function may be included. Further, an embodiment may have an inflation means such that the inflation maintains in the bladder(s) even after the inflation means is removed. Such inflation means may be integral to the compression apparatus itself or may be removable. Such inflation means may include an integrated circuit and/or wireless capability for tracking of usage, pressure, compliance by the patient in regard to maintaining certain pressures recommend by a physician or part of such patient's treatment plan, and other health data such as standing pressure and moving or working pressure, pedometer (number of steps), heartbeat, blood pressure and any other possible monitoring of the patient. Depending on the feedback obtained the inflation means may be programmed to increase or decrease the pressure without manual changing by the patient. Further, the inflation means may be configured so that the physician or other treatment professional may increase or decrease the pressure remotely based on the feedback. Other combinations may be included such as manual changing of the dial or inflation means in combination with automated means or electric means or digital means.
[0116] The system may also include other sensor such as a tonometer, which is a device pressed into the skin to measure the amount of force required to make an indent in the tissue. The resulting measurement can help gauge the degree of firmness or fibrosis (tissue scarring) under the skin, which is a consequence of worsening lymphedema. Such a tonometer could be applied to the patient's skin under the therapeutic compression apparatus 200 and measure the firmness or fibrosis at such treatment site on the limb of the patient. Such a tonometer could be connected to the inflation means via Bluetooth or other digital means and provide feedback to the patient and medial staff as discussed above.
[0117] In another embodiment, the inventive therapeutic compression system 100 has sensors that measure the positioning and movement of the therapeutic compression apparatus 200, 300. Such sensors could be interpreted to give readouts (via the interface, a plug-in to a computer, or sent to an app) to the user or clinician as to the compliance, activity (pedometer to measure steps, stairs climbed, etc.), and give advice/alerts to improve the treatment. In one such embodiment with sensors, the therapeutic compression apparatus 200, 300 would be programmed to automatically adjust the type and level of compression administered—for example, it is known in the art that while walking static compression is adequate for lower-leg compression therapy so if the sensors detect that the user is walking it would maintain a static, non-intermittent compression of the garment. If the sensor senses that the lower-leg is not walking and is at rest it could either alert the user to switch to intermittent compression or could automatically switch over to intermittent compression to promote blood flow. In one embodiment the sensors would be able to measure skin fibrosis and adjust the level of compression required to improve swelling reduction. These sensors listed are not limiting and any other known or future developed sensors could be employed with the inventive system.
[0118] The sensors described above are non-limiting and could be non-digital or digital means may also be employed. A motorized pump and digital display may be used. The valve may include digital or electric means to change or modify pressure at a set rate or intervals or based on feedback from the monitoring means. The system may include various sensors and monitors. Other sensors could be time set for instance if the system was rented so that the system would stop working once the sensor triggered that the rental days or rental hours had expired. In this instance, the sensor could be reset if additional rental time was purchased.
[0119] The inventive therapeutic compression system 100 may be used to treatment a patient post-operation, such as post-operative sclerotherapy procedures. Post-operative sclerotherapy treatment can also be effective with thigh therapeutic compression apparatus 300 wherein a lateral bladder is closed via a closing means (not shown) and either remains in a non-inflated state or may be slightly inflated to a lower pressure level, or could be inflated to any pressure level desire by the patient. In this embodiment, a medial bladder is inflated as part of the post-operative treatment plan to apply compression and pressure to the treatment site. Reference is made to U.S. patent application Ser. No. 16/846,211 filed on Apr. 10, 2020 which is incorporated herein. Other post-operative procedures may employ the same method.
[0120] The inventive therapeutic compression system may be used for other treatments such as lymphedema, CVI, DVT or any other vascular related issue. In use the therapeutic compression apparatus 200 may be placed by the patient, practioner or care-giver on the chosen limb, such as for instance the leg and fastened around the limb of the patient. Moving in an upward or downward position from the knee and/or hip and/or foot, the patient, practioner or care-giver fastens or secures the fastening tabs up or down to the limb. If there arc additional optional straps located on the proximal end of the apparatus the first strap should be closed or secured in a tight fashion so that the therapeutic compression apparatus 200 fits snugly but not too tight and the second strap should be closed or secured in a tight fashion so that the therapeutic compression apparatus 200 tits snugly but not too tight. The patient, practioner or care-giver then removes the valve cap 211 from the valve located on the therapeutic compression apparatus 200 thus opening the inflation port 212, namely the female slip luer 209. The patient, practioner or care-giver then selects a pressure amount of value on the display 157 or dial of the inflation means 150 depending on the treatment and whether the patient will be walking, sitting, lying down or traveling in a vehicle, train or airplane. Once the pressure amount or value is chosen on the dial (such as a given pressure amount such as “35” mm-Hg or a text such as “Walk” or “Air” or “Travel” or “Low” or “Medium” or “High”), the corresponding umbrella valve or switch is activated such that the pressure is thereafter maintained (closed position) or modified so as to maintain the pressure as it changes with the activity or altitude when in use). The patient, practioner or care-giver then inserts an end of the tube 160 portion such as the male luer slip 161 into the inflation port 112 on the therapeutic compression apparatus 200, presses the ON-OFF button 149 of the inflation means 150 or uses the hand pump 165, and the air or fluid is increased to inflate the bladder 202 and thus achieve a desired pressure amount or valve. Again this inflation means may be a hand pump, electric pump, battery-operated pump, remote controlled pump, air pump, gas pump, or any other known inflation means. A number or variety of inflation means can be employed such as a manual pump, hand pump, foot pump, mechanical pump, electrical pump, battery-operated pump, static pump, intermittent pump, varying pump, automatic pump, pneumatic pump, negative pressure pump, suction pump or vacuum, pulsing pump, or any other known or developed source of inflation so as to provide a certain pressure within the bladder so to provide compression in use by the patient. Depending on the inflation means employed such inflation means may be removed and the valve cap replaced and the pressure will not decrease except as noted in the “Air” or “Walk” position. At any point in use the patient, practioner or care-giver can deflate the bladder by either inserting the valve cap so it depresses the valve spring and thus release the air or fluid in the bladder and decrease the pressure, or the patient, practioner or care-giver can reinsert the inflation means and select the “Deflate” or “Release” and the corresponding umbrella valve will be in the open position so as to release the air or fluid in the bladder and decrease the pressure until a deflated state is achieved for the bladder and the therapeutic compression apparatus. The therapeutic compression apparatus can be reinflated and deflated over and over again when in use.
[0121] The method of use of the inventive system is also described in
[0122] The inventive therapeutic compression system 100 described herein can be used for any suitable condition treatable by compression therapy and the like. For example, the inventive system including a therapeutic compression apparatus 200 in accordance with the present invention can be used for compression of the venous system for the treatment of swelling, venous ulcers, CVI, DVT, for the treatment of lymphedema (where it is circulation of fluids in the lymph system rather than in the venous system that is promoted), and the like.
[0123] As shown in
[0124] As shown in
[0125] As shown in another embodiment of the method of use includes one inflation means, one tube or hose connected to the inflation means and the first therapeutic compression apparatus (in this instance the lower leg therapeutic compression apparatus 200), a second tube connected to the first and second therapeutic compression apparatus (in this instance a thigh therapeutic compression apparatus 300) and then a tube or hose connected to an exhaust port in the inflation means and the second therapeutic compression apparatus (in this instance a thigh therapeutic compression apparatus 300). In this example, the thigh therapeutic compression apparatus 300 and the lower leg therapeutic compression apparatus 200 are connected to the other via a tube or hose and one therapeutic compression apparatus (in this instance the lower leg therapeutic compression apparatus 200) is connected to the inflation means via a separate second tube or hose and a third tube or hose connects the second therapeutic compression apparatus (in this instance the thigh therapeutic compression apparatus 300) to the inflation means or an exhaust port. The method as shown in
[0126] As shown in
[0127] As stated herein, the possible therapeutic compression apparatus to be used in the inventive system are only limited to the target limbs or body parts to be compressed or subject to pressure treatments in order to reduce and treat swelling, lymphedema, CVI, DVT or any other medical issue. For instance, the therapeutic compression apparatus could be for a foot. ankle, calf, lower leg, knee, thigh, groin, hip, buttocks, torso, stomach, back, shoulder, chest, arm, elbow, wrist, hand, neck, head, or the like and any combinations thereof. The inventive system of the instant invention described herein solves many problems with the prior art and in the industry and treatment of patients. The therapeutic compression apparatus 200, 300 may be applied on the patient's body part by the patient without the need or requirement of a skilled care-giver as required by current devices and apparatus. It further is capable of maintaining sufficient effective pressure without overpressure complications, maintaining compression and the like.
[0128] The therapeutic compression apparatus 200 of the instant invention of the therapeutic compression system 100 includes a universal inflation port which is configured to be capable of connecting to more than one source of compression or inflation means such that the patient could vary treatment through varying the inflation source and inflation means for the treatment apparatus or device. For instance, a patient using the therapeutic compression apparatus 200 of the instant invention can alternate between a manual or mechanical or electrical inflation means or source of inflation and pressure. Further, the patient can alternate between static or intermittent inflation and pressure when using the inventive system and inflation means 150 pumps.
[0129] The inventive therapeutic compression system 100 also reduces the problem of lack of mobility in that the inflation means is not integral to the therapeutic compression apparatus and instead the patient can walk about and go to work, school, recreational activities. The inventive system includes an inflation means which is not tethered to a wall outlet and instead is a main pump which is configured to either apply constant static pressure at one pressure level, or constant at static pressure at a choice of different pressure levels, or intermittent pressure at one level, or intermittent pressure at multiple pressure levels, or a choice of either constant static pressure level and intermittent pressure levels. The ability to switch between pressure levels and/or switch between constant static pressure and intermittent pressure promotes a more effective treatment for CVI, DVT and/or lymphedema and other treatments.
[0130] Another embodiment (not shown) may include a variety of sensors so that the pump on its own may adjust the pressure level or switch from intermittent pressure level (which the patient is sitting or the leg is elevated) to constant static pressure (when the patient is walking or running). Such sensors may be connected to a database accessible by a medical provider which could remotely adjust the pressure levels or status change from intermittent to constant or the reverse.
[0131] The inventive system may be used as a prophylaxis or as part of a treatment plan which is easy for the patient to use at home or work (outside a hospital setting or with the aid of a medically trained professional as noted above) which is ambulatory so that the patient can walk and return to life activities. The inventive system can be used as a prophylaxis for swelling in any body part. The system can also be used in pre-operative and post-operative treatments for many different surgeries including but not limited to knee surgeries, hip surgeries, TKR, KRA, TEM, HRA, sclerotherapy and many other surgical procedures regarding other libs or body parts which could have an increased risk of CVT and/or DVT. The inventive system may be used to prevent, reduce or even treat DVT and the system is practical to use, mobile and easy to be administered by the patient post-operative total knee replacement of any other knee, hip or leg surgery. Further the inventive system could also be used in HPIPC treatment and this inventive system can be easily administered by a patient in the home setting as well as a rehabilitation setting or nursing home setting.
[0132] The inventive system includes an inflation means which is less bulky than known systems. The user can thus return to life activities sooner than with known compression systems, prophylaxis systems and other treatment systems which limit the user's ambulation both within and outside the home due to power constraints (electrical, mechanical, battery, manual, etc.) on the system. Further, the inventive system may include one or more sensors to measure the user's limb in regard to pressure on the skin, motion of the limb, blood pressure, tonometer sensor, GPS sensor, and the like while the system is in use. Such sensors may be connected to the inflation means so as to regulate the pressure from the inflation means and either increase or decrease the current pressure level(s). Such sensors may also be connected to a database and possibly accessible to a medical professional and/or the user in real time or as saved over time.
[0133] Additionally the system incudes multiple of compression garments which each therapeutic compression apparatus may have separate active pressure levels at the same time or can vary over time and based on the user's activities.
