Field of the Invention

[0002] The subject invention is directed generally to compression wound dressings and more particularly to a pre-formed absorbent wound dressing including a bladder for applying compression to a body part such as a foot, ankle, calf, lower leg, knee, thigh, full leg, hip, torso, chest, shoulder, arm, elbow, wrist, hand, neck, head or any body part of an individual, optionally in conjunction with a bolster dressing, elevation member, or another dressing with a medication imbedded within it for use to treat a wound during trauma or for post-surgical uses such as knee or hip replacements or in the treatment of conditions such as ulcers, vein thrombosis (DVT), chronic venous insufficiency (CVI) and lymphedema.IL Background of the Related Art

[0003] Wound dressings for centuries has concentrated on cotton or gauze bandages that absorb exudate from a wound, but then have the problem of leakage onto the user’s clothes, bedsheets, furniture and other objects. There are a number of tapes and bandages that are available for application to a wound site or ulcer but they require a skilled medical professional to apply in rolled form onto the target body part with enough tension to keep the wound dressing on the target body part as the person goes about their daily life with walking, moving arms, head, and other body parts. Further, in cases of emergency the medical professional needs a wound dressing that can be applied immediately to the wound site without the time and skill of rolling bandages and wound dressings on the target body part. The anatomy and structure of the foot, leg, though, hip, torso, arm, shoulder, head and other body parts cause problems with adhesion and pressure of known wound dressings complicating any treatment and healing, as well as leakage or exudating of the wound site onto the individual’s sock, clothing, bedsheets, couch and the like.

[0004] Wounds or ulcers on the foot are typically hard to treat due to the structure of the foot and fact that the foot is moved and under pressure when walking. Conventional bandages do not adhere to thefoot, either on the top of the arch or below on the sole of the foot Further, the foot area may become hot and moist contributing to lack of adhesion yet a diabetic foot may be extremely dry and the adhesive must be chosen not to irritate or affect the dry skin of for example a diabetic individual. The structure of the foot is also problematic in keeping a bandage or wound dressing in place and adhered to the foot On the other side of the body any wound or ulcer on the head, face, scalp or neck is likewise hard to treat due to the structure of the head and bleed factors due to the structure of skin over the skull and bony prominences of the head. Any wound or ulcer bleeds more on the foot or head or for example elbow of hand than a similar wound or ulcer on other body parts. A need exists for a pre-formed absorbent wound dressing for body parts to address wounds, exudate and application to the target body part at initial dressing as well as being able to open and check on the wound after application while being able to reclose said wound dressing by the individual themselves without a skilled medical provider while at the same time applying therapeutic compression onto the wound site.

[0005] Diabetic ulcers may affect the foot resulting in exudating wounds. These ulcers may be on the bottom or under sole of the foot, on the toes, between the toes, on the top of the foot, on the arch of the foot and even on the ankles and heels of the foot. Diabetics may have more foot ulcers sometimes related to a complication called neuropathy that causes the individual to lose feeling in his / her / their feet A scrape, cut or puncture in the skin can turn into an ulcer, but the individual might not know it’s there if they have neuropathy and do not feel the wound or pain from the wound. Ulcers can lead to infections and in extreme cases the infection will not heal resulting in partial amputation of the individual’s foot or toe(s). It is estimated that about 15% of people with diabetes in the United States will get a foot or toe ulcer and around 14% to 24% of people with diabetes in the U.S. need an amputation after they get an ulcer. Diabetic foot ulcers are the leading cause of foot amputations. As of 2020, of the estimated 537 million people worldwide who had diabetes about 19% to 34% will develop a diabetic foot ulcer in their lifetime. Unfortunately, of those individuals who develop a diabetic foot ulcer, approximately 20% of them will require lower-extremity amputation, either minor (below the ankle), major (above the ankle), or both. More than 80 percent of amputations start with a foot ulcer. Even more extreme, of those who develop a diabetic foot ulcer about 10% will die within one year of their first diabetic foot ulcer diagnosis. Further, foot and toe ulcers can happen to many people but might be more common in Black, Native American and Hispanic people. If the individual has an eye, kidney or heart disease related to diabetes, they are also at a higher risk Of those about 15% of people with diabetes with an ulcer, the ulcer is typically on the bottom of their foot. Some of those people will be hospitalized because of complications.

[0006] Individuals are also at a higher risk of getting foot and toe ulcers if they have any of the following conditions: blood circulation issues, heart disease, obesity, a foot condition like a bunion or hammertoe, kidney disease, and some lifestyle behaviors of using tobacco and alcohol. Ulcers are open wounds in the skin that can take on almost any shape. Some shapes are more common than others on specific parts of thebody. For example, ulcers on the foot or toe might be shaped like a crater or a wedge. The ulcer can go down even into the bone resulting in amputation or even death.

[0007] Neurotrophic ulcers occur primarily in people with diabetes, although they can affect anyone who has impaired sensation in their feet. They can be found anywhere on the feet but typically develop on the parts of the feet and toes that are most sensitive to weight (pressure points). Neurotrophic or diabetic ulcers on the foot can occur on the sole of the foot, heel, and under the toes as well as the top of the arch. While neurotrophic or diabetic ulcers don’t cause pain based on the lack of feeling on the foot due to neuropathy, this can be worse because the individual will not realize they have an ulcer until it is weeping or exudating. Further, autonomic neuropathy is associated with decreased production of sweat and components of the natural moisturizing factor leaving the skin dry that leads to disruption of the epidermal barrier resulting in dryness and the presence of fissures or cracks that may become a portal of entry for bacteria on the foot and even in between the toes. Areas with blisters, cuts, scratches, redness, or hemorrhage are indicative of local damage from local trauma, friction, or shear commonly caused by walking barefoot and poorly fitting footwear. Callus formation is a reaction to increased local pressure and heralds impending skin breakdown and ulceration. Yet another complication is a fungal infection which is not uncommon in the feet of diabetics. The most occlusive areas are the fourth and fifth toe web spaces allowing excessive moisture accumulation that promotes fungal proliferation as evident by skin maceration in the area as yet another complication on diabetic foot Diabetic foot ulcers that aren’t treated promptly can cause major complications. In addition to being significantly more susceptible to ulceration, a diabetic patient will also generally take a significantly longer period for such ulceration to heal. It is not uncommon for it to take 10-12 weeks for an ulcer on the foot of a diabetic patient to heal even when using a cast or other more permanent treatment or therapy where the individual may be on crutches with complete off-loading of any weight or pressure on the foot. In comparison, such an ulcer would likely heal in less than seven days in a healthy individual. A need exists for a wound dressing that is easy to apply by the individual alone or by a medical professional, exudates the ulcer or wound and applies compression thereby improving circulation, healing times, reducing complications and assisting in healing and pain reduction overall.

[0008] Arterial ulcers may be caused by a condition called peripheral arterial disease which reduces blood flow to your extremities. When this happens the foot tissue may start to die. The ulcers that form from reduced blood flow are called arterial ulcers. Arteries are blood vessels that transport blood from the heart to the rest of the body, inducting the feet and toes. Anyone can get an arterial ulcer, but individuals who smoke or have diabetes, high blood pressure or high cholesterol are at higher risk. Unlike neurotrophic ulcers, arterial ulcers can form on many parts of the foot, including on the tips of the toes, between the toes typically where the toes rub together, the nail bed on the top of the toes, and the bony parts of the feet and toes that rub against bed sheets, socks or shoes, and even.

[0009] Both diabetic ulcers and arterial ulcers are wounds or open sores that do not heal, or otherwise recurrepeatedly, and cause persistent swelling as well as burning, itching, irritation and discoloration of the skin. Conventional treatment and therapy for such ulcers generally includes topical protection of the wound, as well as compression and antimicrobial treatment of the affected area. Other treatment plans include draining the ulcer or wound site, orthotics to try to reduce or shift pressure points on the foot, removing pressure from the area by wearing a cast, elevation of the foot for extended periods of time (which is difficult for individuals working), debridement and removal of infected tissue, plantar exostectomy which is removal of parts of the sole of the foot, shaving or removing bones that in infected, tenotomy which is removal of scar tissue that has developed at the ulcer or wound site, and even reconstructive surgery using skin grafts to replace the infected ulcer or would site.

[0010] Other wounds that need immediate attention may be emergency situations such as automobile crashes, explosions, fires, and other traumas. The medical professionals in that instance may be an Emergency Medical Technician in an ambulance arriving at the scene of a trauma and needing to control bleeding immediately. Time is of the essence in such situations and a pre-fbrmed absorbent wound dressing including a bladder for compression would greatly enhance bleeding control and reduce risk of contamination at the wound site. For example, head wounds bleed at a higher rate than leg wounds due to a large amount of tiny arteries and veins serving the individual muscles and skin on the head, including superficial arteries and veins close to the surface of the skin on the head. It is noted that sometimes even small lacerations to the head can lead to very large amounts of bleeding that need to be controlled immediately. Thus a need exists for a pre-formed wound dressing including a compression bladder to assist in stopping or controlling bleeding for application to the scalp and / or head.

[0011] Further wounds that need attention include various post-surgery wounds such as by way of example only liposuction, sclerotherapy, knee and / or hip replacement, and any surgery on the foot, leg, hip, elbow, hand, arm, shoulder, torso, chest, neck and head or any other body parts. These wounds require exudation, removal of body fluids, keeping out infection, having some moisture but not too much to promote healing, and are prone to repeated replacement as well as slippage of the wound dressing on the body part if the patient is ambulatory and moving around, even if that movement is within a bed. Thus a need exists for a wound dressing with less slippage once applied to the target body area including a therapeutic compression bladder.

[0012] There are a number of tapes and bandages that are available for application to a wound site or ulcer but the anatomy and structure of the foot, ankle, leg, knee, though, hip, shoulder, arm, elbow, wrist, hand, neck and head causes problems with adhesion, pressure complicating any treatment and healing, as well as leakage or exudating of the ulcer onto the individual’s clothing, bedsheets, couch and the like. A need exists for a wound dressing on the foot, ankle, leg, knee, though, hip, shoulder, arm, elbow, wrist, hand, neck and head for ulcers or any type of wound including a therapeutic compression bladder to apply compression thereby improving circulation and overall healing. Notably, common wounds, scrapes, cuts and the like onthe foot, ankle, leg, knee, though, hip, shoulder, arm, elbow, wrist, hand, neck and head take longer to heal even in healthy individuals again due to the anatomy and structure of the target body part. Further complicating the situation may be traumas such as surgery, car accidents, explosions, fires, and other emergencies where there is massive bleeding and time is of the essence in order to stop the bleeding and triage the wound site whether on a bony prominence or certain anatomy as well as any other treated body part. These body parts would benefit with a wound dressing including a compression bladder to assist in controlling and / or stopping bleeding at the wound site.

[0013] A need exists for a wound dressing including a compression bladder for any wound on the foot regardless of whether the individual has diabetes, circulation issues or is a healthy individual with a foot wound. As of2015, costs related to diabetic foot ulcer s alone were greater than $1 billion annually and rising yearly. As of 2022 it was estimated that overall diabetes care in the U.S. accounts for an estimated $273 billion in direct and $90 billion in indirect costs annually. Foot complications such as ulcers and infections represent a major source of costs among people with diabetes, leading to higher rates of hospital admission, emergency department visits, outpatient visits and home health care utilization, and excess annual expenditures of 50% to 200% above the baseline cost of diabetes-related care. Advanced-stage ulcers cost upwards of $50,000 per wound episode, and direct costs of major amputation are even higher. These numbers likely underestimate the true economic burden of diabetic foot ulcers given out-of-pocket expenses, loss of productivity, and decreased employment associated with diabetic foot ulcers. A need exists for a treatment plan to improve healing times and outcomes while reducing complications such as infections and amputations for diabetic foot ulcers as well as arterial ulcers, while also improving function and quality of life and reducing health care costs. A further need exists for a wound dressing that includes a bladder for compression on the foot, leg or other body part to assist with healing and reducing complications.

[0014] For those individuals with circulation issues, foot and leg ulcers are problematic as the muscles, veins and arteries are not healthy in the individual’s leg or foot resulting in worsening ulcers. Normally, a healthy muscle, for example, a healthy leg muscle squeezes the deep veins of the legs and feet to help move blood back to the heart. One-way valves in the deep leg veins keep blood flowing back towards the heart However, prolonged periods of standing or sitting can cause the walls of the deep leg veins to stretch. Over time, in susceptible individuals, this can weaken the vein walls and damage the valves, causing blood to pool in the veins and increase venous blood pressure. This may result in a condition known as chronic venous insufficiency (CVI). Treatment of CVI typically involves the use of compression stockings or medical hosiery to decrease chronic swelling. Compression stockings are elastic stockings that squeeze the veins to improve venous circulation and prevent excess blood from flowing backward. Compression stockings can also help to heal skin sores or stasis ulcers that often present in conjunction with CVI. It is also common to employ compression bandages to apply pressure to the leg. In this regard, a bandage is applied with constant tension so as to produce graduatedcompression with the highest pressure at the ankle. However, the technique is difficult and is often done by highly skilled healthcare professionals.

[0015] The current method of treatment for ulcers, typically on the lower leg, foot, thigh, hip, torso, shoulder, arm, elbow, wrist, hand, neck and head includes placing a wound dressing over the ulcer or skin area to keep the skin moist and prevent infection from entering the open wound or sore and to assist in healing or closing the open wound or ulcer. Depending on the patient though this time frame can be much longer than days but lead into weeks or even months where the ulcer does not close or heal and in some patients the ulcer never fully heals or closes. Currently venous and related wound dressings are limited to various bandages and dressings that the care giver must wrap around the lower leg and then add some sort of securing means such as surgical tape or other medical grade tape. The care giver must learn how to wrap the dressing around the target ulcer skin area to keep it tight so that the open sore does not ooze onto the patient’s clothes or bed linens while not wrapping it too tight to inadvertently cut off circulation in the limb. This is a very long learning curve in managing the tightness at the right level for the caregiver to learn over time. The actual patient usually cannot apply the wound dressing themselves as they may be bed ridden or non-ambulatoiy. Thus, a need exists for an absorbent wound dressing that is pre-formed in the shape of a limb or extremity which includes a compression bladder for use in the treatment of wounds, post-surgical locations on the body, venous ulcers, CVI, lymphedema and DVT.

[0016] Further, the state of the art of bandages has been the same for centuries, using cotton and gauze material to absorb the exudate such as blood, pus, weeping edema and the like. Historically, wet-to-diy dressings have been used extensively for wounds requiring debridement. In 1600 BC, it is noted that linen strips soaked in oil or grease covered with plasters was used to occlude wounds. Traditional wound dressing products including gauze, lint, plasters, bandages (natural or synthetic) and cotton wool are dry and used as primary or secondary dressings for protecting the wound from contamination. Gauze dressings made out of woven and non-woven fibers of cotton, rayon, polyesters afford some sort of protection against bacterial infection. Some sterile gauze pads are used for absorbing exudates and fluid in an open wound with the help of fibers in these dressings. These dressings require frequent changing to protect from maceration of healthy tissues and thus are costly and time consuming, both for the patient and the medical profession. Further, due to excessive wound drainage, dressings become moistened and tend to become adherent to the wound making it painful when removing.

[0017] Generally in the 1980s- 1990s wound dressings developed to facilitate the function of the wound rather than just to cover it. These dressings are focused to keep the wound from dehydration and promote healing. Current conventional wound dressings may be based on synthetic polymers and are classified as passive, interactive and bioactive products. Passive products are non-occlusive, such as gauze and tulle dressings, used to cover the wound to restore its function underneath. Interactive dressings are semiocclusive or occlusive, available in the forms of films, foam, hydrogel and hydrocolloids. These dressings actas a barrier against penetration of bacteria to the wound environment. Current wound dressings are supposed to provide moisture while also absorbing fluids and include hydrogels, hydrocolloids, alginates, synthetic foam dressings, silicone meshes, tissue adhesives, vapor-permeable adhesive films and silver / collagen containing dressing. However, the need to combine the wound dressing with compression therapy remains problematic for both the user and the medical profession. The level of compression and the maintenance of that compression level needs to be addressed while at the same time a wound dressing underneath the compression garment has to exudate the wound but still maintain some level of air. Thus a need exists for a wound dressing including a bladder, which bladder may be gradient so that gradient pressure and / or gradient compression is applied to the target body area.

[0018] Historically for the last century or longer bandages were the main wound dressing. There are three main components to typical wound dressing, notably though not limited to venous ulcer wounds or lymphatic wounds or wounds related to edema and leg swelling. Bandages was key role to do multiple steps in the manage of wound care. Sometime the bandage acted as a wound dressing, absorbing the drainage aka exudate management while also providing very limited compression therapy. Bandages for the last 30 years included wound dressing technology adding optional materials (alginates, foams, skin substitutes) and properties (silver impregnated). Bandages have progressed by adding multiple layers and improving the compression properties. Multi-bandage can absorb more fluid and have slower compression decay with more inelastic properties than a single layer gauze bandage. But the problem remains that the bandage, even if multiple layer, needs separate layers to manage the wound exit exudate and a then add a second or multiple layers for compression. This treatment plan requires a skilled care giver to do it properly and very importantly such compression bandages are not reusable. In use, such conventional and known compression bandages must be cut off to see the wound below the wrapper bandage. This in turn traps the patient into being seen by a clinician if there is treatment and severely limits the patients ability to engage in common tasks such as bathing, etc. Such a need exists for an absorbent bandage in combination with a compression bladder that can be removed by the patient without medical assistance and is reusable, both to save cost and time on behalf of the patient and all medical professionals such a clinicians.

[0019] Another problem exists especially with exudating or draining wounds in that any compression bandage once becoming wet in contact with the exudating liquid, loses most if not all compression levels. Further, the liquid is trapped against the skin of the patient causing discomfort, irritation, maceration or worsening of the symptoms, infection and other complications. Many wounds including post-surgical wounds and venous ulcers that exudate have metabolic waste and proteins that prevent healing so leaving the fluid in contact with the wound is counter-productive for healing. Having a waterproof backing layer is not sufficient as the wound still requires some level of measurable air to assist in healing. Thus a need exists for a wound dressing including a bladder that has measurable air while not promoting leakage onto the patient’s clothes or bedsheets or furniture, exudates the wound, applies compression therapy at a consistent level andis reusable.

[0020] From a lifestyle and economics view, in regard to venous wound care most visits to medical professionals such as clinicians are for everyday dressing changes and not for monitoring the progress of the wound, thereby causing increased costs (to the patient, the insurance company and even loss of other billable time for the medical provider) and time management of all involved. This creates a large burden to health care system due to medical professionals such as clinicians basically removing and reapplying compression bandages every few days for patients resulting in lost opportunity to do other procedures and cost to the insurance companies, Medicare, and the patient’s co-pays every few days for weeks, months or even years on end. For the medical professional who is tasked with removing and then applying a new compression bandage, he or she will cut off and remove the typically soaked foul smelling bandage with debris flying around and leaking liquids, pus, blood and the like, then cleaning off the exudating and foul-smelling wound site and finally having to wrap the new replacement compression bandage around and around the wound site. This is a messy, odorous and arduous procedure which the clinical or medical professional may repeat ever few days for every single patient, over and over again for weeks, months or even years. Further, the patient has multiple burdens on their time to travel to and from the medical office every few days, economic costs and notably reduced quality of life as not able to engage in everyday activities such as bathing and the like. In addition, the clinical or medical professional may need an assistant depending on the body part being treated as in certain cases a swollen leg can weight 100 pounds itself, which needs to be lifted while being conventionally bandaged. A need exists for a pre-formed wound dressing that the user himselflherself can apply with their own two hands, or a clinical or medical professional can apply without needing assistance from a second clinical or medical professional which includes a bladder for compression therapy.

[0021] The treatment using conventional compression bandages may not be effective for certain conditions such as lymphedema where the entire leg weeps resulting in drainage through the skin without a specific ulcer being present on the skin. Further, for some post-operative patients there is localized swelling or acute swelling or seepage from a surgery cut resulting in high level of exudate or liquid to be absorbed by the compression bandage. Again, in these instances the compression level of the compression bandages is significantly reduced or even eviscerated to zero compression. This a need exists for a wound dressing including a bladder that can compress the limb while absorbing exudate and fluids such as blood or pus while at the same time maintaining the target compression level. Indeed another problem with maintaining the compression level of a compression bandage is that once the immediate swelling is reduced then the compression level is directly reduced as the circumference of the limb is lower resulting in gaps and lower compression or zero compression.

[0022] Another conventional wound dressing of plasters or other such as the Unna boot may be helpful for the impregnated additives to assist healing, but such materials and wound dressings do not have compression. Such materials may be comprised of a pad or alternative wound contact dressing with impregnated materialsbut no compression therapy is available even when first applied, never mind when the initial swelling is reduced and then there is a gap between the skin of the patient and the set plaster or Unna boot.

[0023] The inventive pre-formed wound dressing including a bladder and the system solves these and other problems and fill many needs by providing a multi-layer system which is comfortable, non-stick, absorbent, and has backing layer that prevents strike through leakage onto the user’s clothes or other materials such as furniture while at the same time enabling vapor transfer so it is not occlusive which no build up in Co2 or bacteria growth, thus assisting in healing and pain relief while reducing complications to the patient and also providing cost savings to the user and the medical field as a whole. The inventive pre-formed wound dressing including a bladder and the system addresses these and other problems and issues for the medical field and the patient or user. A need for a wound dressing compression system that provides measurable air to the wound site, a compression level that is maintainable throughout the treatment plan, is capable of selfapplication by the patient including being able to remove the system and reuse it, is met by the inventive wound dressing compression system. Notably, anyone can properly place the wound dressing compression system on the user in a more effective way than known conventional compression bandages, which reducing edema and assisting in wound healing.

[0024] As stated above, many known wound dressing and bandages have added waterproof backings to assist in leakage of exudate problems, but for compression needs the waterproof backing reduces the compression levels. This is notably important for treating venous ulcers, pressure ulcers, and conditions such as edema, lymphedema, chronic venous insufficiency (CVI), Deep Vein Thrombosis (DVT), Cerebral Venous Thrombosis (CVT), and other types of conditions related to circulation, veins, and pressure points as well as emergency traumas being treated at the location outside a medical facility such as an automobile accident, fire, explosion, gun shooting, war zone and the like. Turning to certain treatment plans or methods to treat CVI and lymphedema, compression bandaging is typically employed but has several disadvantages. The bandaging is time consuming, and the effectiveness is limited to the skill of the provider. In some instances, bandages can be applied too tightly or too loosely and may slip from their intended position, decreasing their effectiveness. When this occurs, bandages must be taken off and reapplied, further increasing the time of application and decreasing the consistency of application of the therapy. Further, when the compression bandaging is on the leg, thigh, knee, arm, shoulder, torso, chest or other area of the body the bandaging slips down the leg, arm, or other body part when the user walks or moves around even in bed, possibly due to the anatomical shape of the tapering downward of the body part. Further, compression dressing is typically non-absofbent so therefore the patient has leakage or oozing from the wound such as a leg ulcer, that leaks onto bed sheets or clothes. Thus a need exists for a pre-formed absorbent wound dressing including a bladder to apply to the patient or user’s limb or extremity more easily than current wound dressings, avoid or reduce slippage and apply compression therapy to the wound site.

[0025] The effectiveness of many of the current compression therapies is also limited by the application ofcurrent products. Because current compression therapy is done either with manual wraps or electromechanical systems, they require either a skilled medical processional to apply and / or the need for the patient to be stationary for extended periods of time. Although stockings and / or bandages can be worn by patients and self-administered, they are very difficult for the patient to put on and pose a challenge for unskilled medical professionals to apply consistently and effectively. Again though, the stockings and / or bandages will slip down the thigh towards the knee or down the calf to the ankle once the user walks or moves around. The same is true for bandages or wound dressing on the lower or upper arm, torso, chest, neck or head as well.

[0026] CVI and lymphedema may also result in DVT, which is an affliction that causes blood clots particularly in the lower extremities of the legs. When a patient is not ambulatory, the patient faces an elevated risk factor of creating a blood clot. These blood clots, which often accumulate or reside in the patient's calf or thigh, are not, in and of themselves, overly dangerous. However, when the blood clot breaks loose, they create a pulmonary embolism which can get lodged in the patient's heart, brain or lungs where it can cause significant damage or death. It is estimated that in each year 2 to 2.5 million Americans are afflicted by DVT causing 600,000 patients to seek medical care with 300,000 patients succumbing to the effects of the pulmonary embolism. Among people who have had a DVT, one-third will have long-term complications (post-thrombotic syndrome) such as swelling, pain, discoloration, and scaling in the affected limb. Further, about one-third (about 33 percent) of people who are diagnosed with blood clots will have a recurrence within ten years. Thus, a system and apparatus and method of use to prevent, reduce and / or treat DVT is needed which is easy to use by the patient at home, ambulatory in that the patient can work and walk about both inside and outside of the home, and less cumbersome than cunent known DVT systems. The number of Americans who suffer from DVT may be affected or have an increased risk based on (a) recent surgery, which decreases a patient's mobility and increases inflammation in the body, which can lead to clotting; (b) medical conditions that limit mobility, such as an injury or stroke; (c) long periods of travel, which limit mobility; (d) injury to a deep vein; (e) inherited blood disorders that increase clotting; (f) pregnancy; (g) cancer treatment; (h) smoking; (i) obesity; and (j) many other conditions. Thus, a system and apparatus and method of use to treat DVT is needed including for a wound dressing including a bladder which dressing does not promote leakage onto the patient’s clothes or bedsheets or furniture, exudates the wound, applies compression therapy at a consistent level and is reusable.

[0027] Many of the current treatment options for CVI and lymphedema cause venous ulcers including the use of current known devices, apparatus, bandages, stocking, hosiery and the like. A venous ulcer is damage and loss of skin above the ankle that is the result of a problem with the veins in the leg. Venous ulcers typically develop on either side of the lower leg, above the ankle and below the calf. They are difficult to heal and often recur. They also develop on the thigh, on the inner portion of the leg thigh orouter thigh area as well as near the groin area on the leg. Further, venous ulcers may develop around the knee, behind the knee, along the sides and on the front of the knee as well. These venous ulcers may ooze blood, pus or other liquids thus requiring constant wound dressings applied to the target area or limb. Current wound dressings lack support or shape of the target limb or extremity and are instead typically flat and wrapped around and around the target limb or extremity. A need exists for a preformed absorbent wound dressing in the shape of the target limb or extremity including a bladder that applies compression therapy at a gradient pressure level and is reusable.

[0028] The veins of the leg are divided into the superficial and deep systems according to their position relative to the fascia. The deep veins, which come together to form the popliteal and femoral veins lie within the fascia and are responsible for the venous return from the leg muscles. Dilated valveless sinusoids also lie within the fascia (more particularly in the soleus and gastrocnemius muscles). The sinusoids fill with blood when the leg is at rest. The long saphenous vein which runs along the medial side of the leg from foot to groin and the short saphenous vein which runs at the back of the calf from foot to knee are the major vessels of the superficial venous system. These vessels lie outside the fascia and are responsible for the venous return from the skin and subcutaneous fat. Compression on the long saphenous vein may be recommended in treatment of certain conditions whereas in other conditions there may be less compression recommendation on the long saphenous vein on the medial side of the leg and more compression recommended on the short saphenous vein of the leg which runs on the back portion of the leg, including the thigh. Communicating veins, sometimes called perforators because they perforate the deep fascia, join the two systems. The perforators, like the other veins in the leg, contain valves that permit the flow of blood in one direction only, from the outer or superficial system inwards to the deep veins.

[0029] The venous pressure at the ankle of a subject who is lying supine is around 10 mmHg, but on standing this will rise considerably due to an increase in hydrostatic pressure (equivalent to the weight of a vertical column of blood stretching from the point of measurement to the right auricle of theheart). During walking, as the foot is dorsally flexed, the contraction of the calf muscle compresses the deep veins and soleal sinuses thereby emptying them of blood. As the foot is plantarly flexed, the pressure in the veins falls, the proximal valves close, and the veins are refilled by blood passing through the perforators from the superficial system. During this cycle, in a normal leg, the distal valves of the dee veins and the valves of the perforators will ensure that the expelled blood can go in only one direction- upwards, back to theheart. Blockage or damage to the venous system will cause disruption to normal blood flow, which may manifest itself in a number of different ways according to the site and extent of the damage. If the valves in the superficial system are affected, venous return will be impaired and blood may accumulate in the veins causing them to become distended, leading to the formation of varicosities (varicose veins). Such varicosities may be located in the thigh, knee, calf, ankle or foot area of the user's leg.

[0030] If the function of the perforator valves is impaired, the action of the calf muscle pump will tend tocause blood to flow in the reverse direction into the superficial system increasing the possibility of damage to the superficial vessels. Again, the current compression therapy is done either with manual wraps or electromechanical systems, they require either a skilled medical processional to apply and / or the need for the patient to be stationary for extended periods of time. A need exists for a new system to treat such medical issues. There may be minimal blood flow upward into the thigh and the rest of the body, causing issues for the patient along the body including the thigh, calf, ankle and entire leg of the patient.

[0031] Following a deep vein thrombosis that results in complete or partial obstruction of a deep vein, the unrelieved pressures produced by the calf muscle pump on the perforator valves may cause these to become incompetent. If this occurs, there will be a large rise in the pressure in the superficial system, which may force proteins and red cells out of the capillaries and into the surrounding tissue. Here, the red cells break down releasing a red pigment that causes staining of the skin, an early indicator of possible ulcer formation. The ulcer formation can be in any part of the body, including the leg, groin, thigh, knee, calf, ankle and foot. Venous leg ulcers are generally shallow and red in color. The skin surrounding the ulcer is frequently discolored due to the staining described previously. Incompetent perforating vein valves can also cause malleolar venules to become dilated and appear as fine red threads around the ankle as well as the thigh, knee, calf or foot are of the leg or any area of the leg. This condition, called ankle flair, is also diagnostic of a venous ulcer. The condition may also be seen on the thigh, including the inner medial thigh area or outer lateral thigh area, or around the knee or groin area of the patient's body.

[0032] Arteries transport oxygen replenished blood from the heart to the rest of the body. Veins return oxygen depleted blood back to the heart. When the veins in the lower extremities of the body have difficulty transporting blood back to the heart, a condition develops called chronic venous insufficiency (CVI), also known as chronic venous disease (CVD). CVI. Most commonly occurs as the result of a blood clot in the deep veins of the legs, a disease known as deep vein thrombosis (DVT). CVI also results from pelvic tumors and vascular malformations, and sometimes occurs for unknown reasons. When a person is standing or sitting, blood in the veins of the legs flows in an upward direction. When the person walks, the calf muscles and muscles in the feet contract to squeeze the veins and push the blood upward. To keep the blood flowing upward and prevent it from flowing downward, the veins contain one-way valves. CVI occurs when these valves become damaged and allow the blood to leak back downward in the opposite direction. Such valve damage may occur as the result of aging, extended sitting or standing, or a combination of aging and reduced mobility. When the veins and valves become weakened and the blood does not properly flow up to the heart, blood pressure in the veins of the lower extremities can stay elevated for long periods of time, leading to CVI. This condition is more common in older individuals, and if not properly treated, can lead to burst capillaries, local tissue inflammation, internal tissue damage, varicose veins, ulcers, and open sores on the skin's surface. The burst capillariescan be seen on the patient's leg including the thigh, knee and groin. CVI can diminish the capacity of the venous system and increase the workload of the lymphatic system in the affected area. The lymphatic system must then transport larger volumes of water and protein to reduce the fluid load in the affected tissues of the legs, a situation which is especially difficult for patients with lymphedema, varicose veins, and other lower extremity pathology. One non-surgical option often used to help prevent or treat the leg extremity pathologies discussed above is the use of compression stockings. Compression stockings help prevent leg fatigue, ankle and foot swelling, spider veins, and varicose veins. They improve circulation in the legs, especially when used in conjunction with frequent exercise and leg elevation. Compression stockings maintain pressure on the legs while allowing for normal ambulation. Increasing pressure in the tissues beneath the skin reduces excess leakage of fluid from the capillaries and increases absorption of tissue fluid by the capillaries and lymphatic vessels. In addition, the increased pressure decreases the size of the veins, which causes the blood to flow faster and helps prevent it from pooling.

[0033] Compression stocking tightness typically varies between 15-50 mm HG. The tightness of a given stocking depends on its particular configuration-and class. For example, stockings having a compression pressure of 15-20 mm HG are considered light compression stockings. Class I stockings are 20-30 mm Hg, class II stockings are 30-40 mm Hg, and Class II stockings are 40-50 mm Hg. While such compression stockings are a commonly utilized non-invasive treatment of leg pathology, the issues they present are numerous. Wearing a tightly fitting stocking can be tedious or time consuming to put on, and may require help from another person if the wearer is injured, elderly, or has some form of disability. Any tight-fitting stocking to be worn on the thigh area has a harder time being put on as the user has to pull the tight-fitting stocking over the foot, ankle, calf, knee and finally up to the thigh area. Again, due to the shape of the thigh, these tight-fitting stockings will slip down the thigh at some point due to the user walking or moving about. In addition, the pressure applied by the stocking generally stays relatively constant during use without any option of increasing or decreasing the tightness level. As compression stockings are repeatedly worn, they lose elasticity and thus tightness over time. Once such prescribed elasticity and tightness is lost, the stocking is of little or no value, and needs to be replaced on account of its looseness, which requires buying a new pair to obtain the desired pressure. Further, given the shape of the thigh, the top or upper portion of the stocking must be very tight in order to prevent slippage down the thigh, which can in turn lead to complications of its own due to the excessive tightness. Typical compression stockings are also non-absorbent so require an additional wound dressing on the target area of the ulcer to be applied and then the compression stocking is pulled up over the target limb or extremity. A need exists for a pre-formed absorbent wound dressing in the shape of the target limb or extremity to be applied or placed over the ulcer including bladder for compression therapy.

[0034] Medical hosiery represents a useful and convenient method of applying compression to normalshaped legs in order to prevent the development or recurrence of leg ulcers. However, these stockings are of limited value in the treatment of active ulceration, bring difficult to apply over dressings. In such situations compression bandages currently represent the treatment of choice. Compression bandages apply a pressure to the limb that is directly proportional to bandage tension but inversely proportional to the radius of curvature of the limb to which it is applied. This means, therefore, that a bandage applied with constant tension to a limb of normal proportions will automatically produce graduated compression with the highest pressure at the knee. This pressure will gradually reduce up the thigh as the circumference increases.

[0035] As can be readily appreciated, it is cumbersome and difficult to apply uniform tension to the compression bandage as it is applied to the treated limb, and thus this is accomplished only by highly skilled caregivers. Moreover, once secured to the treated limb, care and attention must be given to ensure that the bandage does not slip or become displaced as this will lead to multiple layers forming, which in turn may lead to localized areas of high pressure, which can place the patient in direct risk of skin necrosis. Further, as most compression dressings are non-absorbent, the provider must apply two layers of dressing, first an absorbent wound dressing and then a compression dressing, requiring even more skill for both dressing applications. Thus a need exists for one piece which is both a wound dressing including a bladder to apply compression therapy while also reducing leakage onto the patient’s clothes or bedsheets or furniture, exudates the wound, and is reusable.

[0036] DVT is widely recognized as a major risk factor facing patients who undergo total hip arthroplasty (THA) and total knee arthroplasty (TKA). Without prophylaxis (preventive treatment), up to 80 percent of orthopedic surgical patients will develop DVT, and 10 to 20 percent will develop PE. Even when proper prevention measures are taken, it is estimated that 3 percent of orthopedic surgical patients will develop DVT, and 1.5 percent will develop PE. DVT and PE remain the most common cause for emergency readmission and death following joint replacement surgeries. In one survey conducted the patients surveyed after a THA or TKA stated problems with their prophylaxis varied widely: 83 percent reported issues with lack of ambulation, 74 percent used compression stockings, 57 percent used mechanical compression, 58 percent used an anticoagulant pill, 46 percent used an anticoagulant injection, and 42 percent used aspirin. (https: / / www.stoptheclot.orn / about-clots / toolkir-for-knee-hip-replacement- patients / orthopedic-surgery-fact-sheet / ). Thus, a need exists for a prophylaxis 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 while also exudating the wound and applying compression therapy through bladder included in the wound dressing.

[0037] Knee replacements may also result in DVT as a post-operative complication. After knee surgery, most DVTs occur in the calf. Although less likely to lead to a PE, these clots are more difficult to detect. Less than one third of patients with DVT present with the classic signs of calf discomfort,edema, distended veins, or foot pain. It has been noted that the risk of developing DVT extends for at least three months after a total knee replacement. The risk is greatest two to five days after surgery; and a second peak development period occurs about 10 days after surgeiy. Currently, it has been noted that patients at home are experiencing an increase in DVT due to lack of activity and movement. While the patient is in the hospital, he or she may be connected to an electrical powered pump in combination with a therapeutic compression apparatus, however, once discharged, the cunent products are limited as noted herein, whereby most therapeutic compression apparatus are manual pumped so the patient can walk, work, etc. and those that are electric powered typically require being tethered to an electric outlet or the electric pump is integral to the therapeutic compression apparatus and not practical to walk about in life. Thus a need exists for a system which can be used to prevent, reduce or even treat DVT which 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. A need also exists for a pre-formed absorbent wound dressing including a bladder applied over a surgical wound that is healing which can be opened to check on the wound site and closed again with one or two hands without the need for a medical professional or skilled caregiver. Further, a need exists so that the user can walk around with the compression profile maintained while not being limited to an electrical plug or some other separate source of continued, maintained or even increased then decreased compression while also having exudation of the wound with a wound dressing that is pre-formed for the target body area.

[0038] Further compression treatments have been discussed in "Effect of High-pressure, Intermittent Pneumatic Compression for the Treatment of Peripheral Arterial Disease and Critical Limb Ischemia in Patients Without a Surgical Option", by Oscar M. Alvarez, Martine E. Wendelken, Lee Markoqitz and Christopher Comfort (Wounds, Vol. 27, Issue 11, pages 293-301, November 2015) wherein thirty-six patients with symptomatic peripheral arterial disease (PAD) or critical limb ischemia (CLI) who were experiencing claudication pain, chronic resting pain, numbness, and ischemic lower leg / foot ulceration were randomized into 2 treatment groups. Eighteen of these patients received treatment with high- pressure, intermittent pneumatic compression (HPIPC) 60 minutes twice daily for 16 weeks, and 16 subjects received standard care consisting of an exercise regimen of walking for 20 minutes twice daily for 16 weeks. The HPIPC device delivers bilateral pressures of 120 mm Hg. Cycle times 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. The study was designed to measure patient-centered outcomes. The primary endpoint was peak walking time (PWT), defined as time to maximally tolerated claudication pain. The conclusion at the end of the study was that therapy consisting of HPIPC for 2 hours daily for a period of 16 weeks significantly improved PWT, reduced resting pain, and improved healing rates, physical function, and bodily pain. There were no device related complications, allowing for long-term use. A further conclusion was that HPIPC offers anexcellent alternative for the palliative care of patients with PAD and CLI symptoms. Thus, a need exists for a wound dressing including a gradient bladder which can be easily administered by a patient in the home setting which includes HPIPC.

[0039] Co-owned U.S. Publication No. 2004 / 0193084, which is hereby incorporated by reference herein in its entirety, discloses a device for applying pressure to the human leg for use in conjunction with treatment of varicose veins. The device includes a flexible member and at least one air bladder chamber integral thereto that are adapted to securely wrap around the human leg. A tube in fluid communication with the air bladder chamber(s) extends to an air pumping mechanism that operates to inflate the air bladder chambers) to a pressurized state. The flexible member preferably includes an opening at the knee joint level to enable a patella to protrude therethrough. In addition, the flexible member preferably extends below knee joint level and is adapted to securely wrap around a lower portion of a leg to provide stability to the leg. Preferably, the air bladder chamber of the device is substantially longer in a first dimension than in a second dimension orthogonal thereto such that the air bladder chamber can be positioned to cover a portion of the human leg that is relatively long in the vertical dimension and narrow in the horizontal dimension. However, this device lacks a wound dressing aspect. Co-owned U.S. Pat No. 7,276,037, which is hereby incorporated by reference herein in its entirety, discloses an apparatus for applying compression therapy to an extremity of the human body, such as a portion of the human leg. The device includes a flexible member and an air bladder chamber. The flexible member is adapted to wrap around the extremity to secure the air bladder chamber to the extremity. An air pumping mechanism is operated to inflate the air bladder chamber to a pressurized state. One or more fluid-filled pressurized members are provided, each separate and distinct from the flexible member and the air bladder chamber and thus readily moveable relative to the flexible member and the air bladder chamber. The pressurized members) is operably disposed between the extremity and the flexible member whereby it applies increased localized pressure to the extremity during use. Preferably, the air bladder chamber is substantially longer in a first dimension than in a second dimension orthogonal thereto such that it can extend longitudinally along the extremity to cover a relatively long and narrow portion of the extremity. The position of the air chamber can be readily adapted to apply local pressure to desired body parts (such as a certain venous channel). The pressurized member(s) can be positioned during use such that it covers a venous ulcer (or other treatment sites) and applies increased localized pressure to the treatment site in order to promote healing. Again this device lacks a wound dressing component necessitating two separate devices. Further co-owned WO 2018 / 052676 and U.S. publications 2015 / 0245975 and 2009 / 0124944, which are all incorporated in whole herein, disclose therapeutic compression apparatus, devices and systems to apply compression on a body part but each lack a wound dressing element and so the medical professional or user would have to first inset a wound dressing on the skin of the user and then apply the compression apparatus or device over the separate wound dressing andthen activate the compression. A need exists for one device or apparatus which is a wound dressing and applies compression at the same time to save cost, precious time, reduce or control or stop bleeding as well as increasing circulation and assist in overall healing while reducing complications. Each of the wound dressing and the separate therapeutic compression apparatus is device has manufacturing and wearing application challenges that are not obvious to combine in one apparatus or device.

[0040] Co-owned PCT / US2024 / 010513 and PCT / US2024 / 042582 which is incorporated in whole herein, discloses a pre-formed absorbent wound dressing in the shape of a selected or target limb or extremity but there is a separate therapy compression apparatus and also the wound dressing has a tendency to slip down on the patient when being worn alone or even if having a second therapeutic compression apparatus over the pre-formed wound dressings. Again, the wound dressing and a separate therapeutic compression apparatus or device has manufacturing, material, functionality and wearing application challenges that are not obvious to combine in one apparatus or device. Thus a need exists for a pre-formed absorbent wound dressing including a bladder which is easier to place on the wound site, ulcer or surgical site wound and lasts longer than common bandages and wound dressings. The preformed absorbent wound dressing including a bladder reduces or eliminates slippage while also applying compression therapy on the target body part, preferably gradient compression and gradient pressure. Further a need exists for a wound dressing including a bladder that has measurable air while not promoting leakage onto the patient’s clothes or bedsheets or furniture, exudates the wound, applies compression therapy at a consistent level and is reusable. Other uses for the inventive pre-formed absorbent wound dressing including a bladder may be envisioned.SUMMARY OF THE INVENTION

[0041] The subject invention is directed to a pre-formed absorbent wound dressing shaped for the target limb or extremity such as a foot, ankle, calf, thigh, knee, leg, torso, chest, shoulder, arm, wrist, hand, elbow, neck, head, scalp or any other limb, with the wound dressing having a bladder to apply compression therapy. The inventive pre-formed absorbent wound dressing including bladder is comprised of multiple layers including a wound contact layer, an absorbent layer, a bladder layer which may be two layers forming the bladder, and a waterproof vapor layer and the wound dressing is configured in a shape to conform to the target limb. The target limb can be any body part but may be a foot, lower leg, though, arm or head of a person, as well as other body parts where wounds are present and hard to shape over such bony area or otherwise shaped area such as the head or scalp. The preformed absorbent wound dressing including a bladder may also include an indicator for when the exudate within the absorption layer has reached a certain capacity level and the inventive pre-formed absorbent wound dressing needs to be replaced. The pre-formed absorbent wound dressing including bladder incudes at least one bladder and depending on target limb may have two, three or morebladders, all connected to one inflation means. The pre-formed wound dressing including bladder is less bulky than known apparatus and combinations. The inflation means includes at least two settings, a setting of constant inflation or pressure and a setting of varying or intermittent inflation or pressure. The inventive pre-formed wound dressing including bladder may include at least one sensor, such as a motion sensor, pressure sensor, blood pressure sensor, tonometer sensor, or other sensors to monitor use of the inventive system by the patient and / or medical professionals. In use, the pre-formed absorbent wound dressing including bladder is placed on the target limb or extremity, secured, and then the bladder is inflated via the inflation means. The wound dressing including bladder may also include a dressing which is impregnated with an additive such as medication, vitamins, anti-bacterial coating, silver or zinc oxide. The wound dressing compression system may also include a wound bolster or other elevating apparatus such as a pre-filled bladder in combination with an absorbent foam or other material adhered to the wound site under or around the pre-formed wound dressing including bladder.

[0042] The pre-formed absorbent wound dressing including bladder is in a shape pre-formed for use on a limb, leg, calf, thigh, hip, pelvis, knee, foot, ankle, torso, arm, neck or other body parts. The preformed wound dressing including bladder has an inner layer that is in contact with the wound site and surrounding skin area, another absorbent layer for the exudate (which absorbent layer may itself be comprised of multiple layers), a bladder layer, and an outer layer that is non-absorbent but allows moisture vapor transfer from the wound site to facilitate and assist in treatment at the wound site as well as healing plus applying compression therapy, and a shaping component so that the preformed wound dressing is in the shape of the target limb or extremity. The pre-formed absorbent wound dressing including bladder includes a securing or closing means as well as in some embodiments an adjusting means. Alternatively, the at least one bladder may be at least two or at least three separate bladders within the pre-formed wound dressing. One or more connecting means may be operatively associated along the first and second peripheral edges of the pre-formed absorbent wound dressing for securing it around the limb. The at least one bladder may be adapted and configured to form a predetermined gradient compression profile and / or gradient pressure profile when the at least one bladder is filled. The gradient compression profile and / or gradient pressure profile may be determined by the location of various spot welds on the bladder to create the gradient compression profile and / or gradient pressure profile and when inflated the inventive apparatus has a SSI which may be at least about 12 or greater. The gradient compression profile and / or gradient pressure profile instead may be determined by the inflation means connected or integral to the inventive pre-formed wound dressing including bladder. In another embodiment, the gradient compression profile and / or gradient pressure profile may be determined by pressure being created in one direction within the bladder by the inflation means and then exiting the bladder through an exhaust port or other exit means. The at least one bladder may also include a plurality of fluid chambers. The inventive pre-formed wound dressing including bladder mayfurther comprise at least one means for adjusting pressure coupled to the at least one bladder for controlling an amount of pressure supplied to the treatment site. In an apparatus with more than one bladder, each bladder is connected to the same inflation means and the inflation means sequentially inflates each bladder, which could be the same or different pressure levels, and once disconnected a check valve within an inflation port on each separate bladder maintains the then current pressure level.

[0043] A method of the invention includes the per-fonned absorbent wound dressing including bladder being placed at the wound site on the target limb by the patient or user and being able to secure it on the target limb with two hands alone and without the aid of a skilled medical provider or caretaker. The user places the inventive pre-formed absorbent wound dressing including bladder on the target limb, removes the adhesive tabs on the closing or securing means and places the adhesive portion on the outer layer of the preformed absorbent wound dressing to close and secure it to the target limb. The pre-formed absorbent wound dressing adhesive tabs can be opened and closed a number of times for the user to check on the wound site. Optionally, the pre-formed absorbent wound dressing adhesive tabs include an end portion that does not have adhesive but can be easily gripped by the user in order to open and close the adhesive tabs to check on the wound site. The closing or securing or fastening means may also be a hook and loop connection or other known securing means. The inventive pre-formed absorbent wound dressing including bladder can be used over any wound such as a surgical site, a cut (whether small or gaping in an emergency situation), an ulcer, a burn or any type of wound. The bladder is then inflated within the pre-formed wound dressing to apply compression therapy. The pre-formed wound dressing including bladder can be used to apply pressure on a wound, a post-surgical site, a trauma site, or used to treat CVI , DVT and / or lymphedema. Optionally a wound dressing impregnated with silver or zinc oxide may be placed over the wound site alone or in combination with the wound bolster. Another embodiment of the present invention includes an assembly according to the invention includes a pressure mechanism having a flexible member for attachment to a limb and an air chamber which may be pumped up into a desired pressurized state, a separate relatively small pre-filled air bladder, an absorbent foam, sponge or dressing coupled to the pre-filled air bladder, and a suction conduit coupled to a source of negative pressure (suction) and in fluid communication with the absorbent foam, sponge or dressing. In a preferred embodiment, the pre-filled air bladder, the absorbent foam, sponge or dressing and the suction conduit are formed together as a unit. According to one aspect of the invention, the flexible member of the pressure mechanism is adapted to wrap around a leg or arm and over the pre-filled air bladder in order to secure the pre-filled air bladder and the foam, sponge or dressing to a wound or ulcer in the extremity. Thus, the flexible member is provided with some fixation structure such as a hook and loop closure mechanism. An air pumping mechanism is preferably coupled to the air chamber of the pressure mechanism in order to inflate the air chamber to a pressurized state. The air chamber of the pressure mechanism is preferably designed to apply pressure along a predefined area (e.g., the saphenous vein of a leg) as opposed to around an entire limb. According to another aspect of the invention, the suctionconduit is located either between the pre- filled air bladder and the absorbent foam, sponge or dressing which is adhered to the small air bladder, or the pre-filled air bladder is formed as a donut with a central opening and the suction conduit extends through the central opening. By coupling the suction conduit to a source of negative pressure, exudate from the wound or ulcer is sucked through the foam, sponge or dressing into the suction conduit.

[0044] One of the methods of the invention include locating a pre-filled air bladder and foam, sponge or dressing over a wound or ulcer on a limb, placing the pre-fonned absorbent wound dressing on the target limb or extremity over the pre-filled air bladder and foam, sponge or dressing, then wrapping the flexible member of the pressure mechanism around a limb with the air chamber located over the pre-formed absorbent wound dressing and fastening the pneumatic pressure mechanism in place with the fixation structure. When the apparatus is properly located and affixed to the limb, the air chamber is inflated, preferably to 30-40 mm Hg, thereby applying pressure to the limb and more specifically via the pre-filled air bladder to the wound. The suction apparatus is activated by turning on the source of negative pressure, and exudate from the wound or ulcer is pulled through the absorbent foam, sponge or dressing into the suction conduit.

[0045] Another embodiment of the present invention includes a pre-formed wound dressing including bladder for applying intermittent pressure to a portion of the human body, such as an area of the human leg, which assists with the healing and treatment of various conditions such as venous ulcers or wounds by promoting blood flow into and out of the area and by increasing drainage. It may include a thigh bladder or a foot bladder and a leg bladder, each having inflatable chambers (at least one and possibly two or more bladders within each apparatus) that accommodate an entering fluid by inflating. The bladders are fluidly coupled by a fluid conduit, and each is preferably equipped with a means for locating it on a portion of the body. In a preferred embodiment, the thigh bladder is positioned between the pelvis or groin or hip area of the user and the knee of the user. As a person walks while wearing the apparatus, a portion of the thigh bladder deflates as the person's leg moves foot (heel) strikes the ground due to the external pressure placed on the foot bladder, thereby forcing fluid out of the foot bladder, through the fluid conduit, and into the leg bladder, which raises the pressure therein. As the person's foot rolls from heel to toe in the standard walking motion, the external pressure from the person's weight is removed from the foot bladder, resulting in the pressure of the leg bladder being higher than the pressure in the foot bladder. Fluid thus flows back through the fluid conduit and into the foot bladder, which then inflates again to its original state, such that the pressures of the foot bladder and leg bladder are equalized. This process repeats as a person walks, thereby creating a pumping or kneading force on the leg as the pressure in the leg bladder intermittently increases and decreases, thereby promoting blood flow, fluid drainage, treatment, and healing to various parts of the leg.

[0046] In another embodiment including a pre-formed absorbent wound dressing including bladder is inthe shape of thigh and / or lower leg depending on the location of the wound or ulcer including a foot bladder, the foot bladder is positioned over a second pre-formed absorbent wound dressing placed around the ankle and foot of the user such that the foot bladder is applied over the wound dressing on a bottom of a foot and the leg bladder is positioned on a lower portion of a leg. As a person walks while wearing the apparatus, a portion of the foot bladder deflates as the person's foot (heel) strikes the ground due to the external pressure placed on the foot bladder, thereby forcing fluid out of the foot bladder, through the fluid conduit, and into the leg bladder, which raises the pressure therein. As the person's foot rolls from heel to toe in the standard walking motion, the external pressure from the person's weight is removed from the foot bladder, resulting in the pressure of the leg bladder being higher than the pressure in the foot bladder. Fluid thus flows back through the fluid conduit and into the foot bladder, which then inflates again to its original state, such that the pressures of the foot bladder and leg bladder are equalized. This process repeats as a person walks, thereby creating a pumping or kneading force on the leg as the pressure in the leg bladder intermittently increases and decreases, thereby promoting blood flow, fluid drainage, treatment, and healing to various parts of the leg.

[0047] In one embodiment of the present invention, the wound dressing including bladder includes an inflation means connected to a belt so the user can wear it around his or her waist in daily use, such inflation means may be connected to the therapeutic compression apparatus by, for example, a hose or a tube, which provides inflation to the bladder within the therapeutic compression apparatus and / or wrap. In another embodiment of the present invention, the wound dressing including bladder includes an inflation means which can switch between constant static pressure levels (different pressure levels such as 20 mm-Hg, 30 mm-Hg, 40 mm-Hg, up to 200 mm-Hg, etc.) and intermittent varying pressure levels, whereby the pressure is applied to the therapeutic compression apparatus via a hose or tube. The inflation means may be capable of sequentially inflating each bladder separately, and then deflating, or repeating the inflation and deflation as required.

[0048] In other embodiments the inflation means is connected to two or more tubes and thereby connected to two or more bladders, whether multiple bladders within one therapeutic compression apparatus or a single bladder within multiple therapeutic compression apparatuses, or a combination thereof. In another embodiment the inflation means includes one pump with a manifold having multiple chambers each corresponding to a bladder within the apparatus or multiple apparatus, such that the inflation means connected to the manifold is connected to multiple hoses which then connected to each separate bladder, for sequential inflation and deflation of each separate bladder. In another embodiment the system includes one or more sensors to monitor movement of the therapeutic compression apparatus, pressure levels, blood pressure of the patient, tonometry of the target limb, or other sensor data. These and other aspects of the contacts of the subject invention will become more readily apparent from the following description taken in conjunction with the drawings.BRIEF DESCRIPTION OF THE DRAWINGS

[0084] The pre-formed wound dressing including a bladder 100, 200, 300, 400, 500 600, 700 has an inner layer 115, 215, 315, 415, 515, 615, 715, 915 in contact with the wound site and skin of the patient or user. The inner absorbent layer 115, 215, 315, 415, 515, 615, 715 may be comprised of a polymer, cotton or any material compatible with human skin and wounds. The inner wound contact layer 115, 215, 315, 415, 515, 615, 715 may be a hydrophilic material such as cotton, linen, foam, sponge, fibers, and other suitable materials that can absorb exudates and other moisture from the wound as well as hydroconductive materials. The inventive pre-formed wound dressing including a bladder 100, 200, 300, 400, 500, 600, 700 includes an outer layer 125, 225, 325, 425, 525, 625, 725 which may be in contact with the clothes of the patient or user or a couch, chair or bed linens if the patient or user is nonambulatory. The outer layer 125, 225, 325, 425, 525, 625, 725 is preferably non-absorbent or less- absorbent. The outer layer 125, 225, 325, 425, 525, 625, 725 may be a hydrophobic material or even waterproof, but should also be able to transfer moisture vapor. The outer layer 125, 225, 325, 425, 525, 625, 725 may be comprised of materials such as paper, film, polymers, rubber, metal and the like. The inventive pre-formed wound dressing with bladder 100, 200, 300, 400, 500, 600, 700 includes a middle or central absorbent layer 120, 220, 320, 420, 520, 620, 720 which can absorb exudates and other moisture from the wound and traps such exudate in the middle layer. As shown in FIG. 4 there is a preformed foot with toe spacers wound dressing 900 without a bladder, though a bladder could be added (not shown) on the portion below the foot. In this embodiment there is an outer layer 925, inner layer 915 and not shown is the middle layer 920 and again a bladder (not shown) could be added which would be 940.

[0085] The inner porous layer 115, 215, 315, 415, 515, 615, 715 may be comprised of any material compatible with human skin and wounds such as for instance a polymer, a nonwoven polyester, fibers, and the like. The inner layer 115, 215, 315, 415, 515, 615, 715 may be a hydrophilic layer or a hydroconductive layer. The inner porous layer 115, 215, 315, 415, 515, 615, 715 may be flexible, porous, and non-toxic. As used herein, the term “flexible” is meant to cover a range of materials, which exhibit one or more properties such as being flexible, compliant, elastic, or memory retentive. For example, “flexible” is also meant to refer to materials that exhibit elastic or memory properties, i.e., the ability for the material to return to its original shape when stresses applied thereto are reduced or eliminated. The flexible material is preferably flexible or compliant, to allow the flexible substrate to be placed on the desired surface (such as skin, organ, tissue, or the like) in a manner that allows the flexible substrate to conform to the topology of the desired surface. Likewise, the flexible material is preferably porous, to allow the exudate from the woundsite, cut, gash, burn, ulcer and the like to pass through or permeate through the flexible material and be trapped in the central absorbent layer 120, 220, 320, 420, 520, 620, 720. By “porous” is meant herein either that the bulk of the inner porous layer 115, 215, 315, 415, 515, 615, 715 has pores, such that the exudate from the ulcer or wound site is soaked up or passed through holes or voids in this inner porous layer 115, 215, 315, 415, 515, 615, 715. For example, the inner layer 115, 215, 315, 415, 515, 615, 715 may also be a wicking layer would be in contact with the wound and skin and may be comprised of a porous material for transfer of the exudates and moisture from the wound to the sandwiched absorbent layer 120, 220, 320, 420, 520, 620, 720.

[0089] The bladder 140, 240, 340, 440, 540, 640, 740 to apply compression pressure onto the target body part may be formed or manufactured separately so as to be inserted in between the outer layer 1 15, 215, 315, 415, 515, 615, 715 and the middle or central absorbent layer 120, 220, 320, 420, 520, 620, 720 during manufacture as shown in exploded views of FIG.s 4-5, 7, 11-12, 16-17 20 and 23-24.Various sizes of the bladder 140, 240, 340, 440, 540, 640, 740 are shown in various embodiments. Not shown is a manufacturing method wherein the bladder 140, 240, 340, 440, 540, 640, 740 is created by connecting or welding two or more materials together as disclosed in co-owned PCT / US23 / 79854 andPCT / US23 / 37286 and WO 2018 / 052676, the entire contents of which are hereby incorporated herein by reference for all purposes. The bladder 140, 240, 340, 440, 540, 640, 740 applies compression pressure onto the target body part when inflated, in this non-limiting instance being an air bladder. The inflated or activated bladder 140, 240, 340, 440, 540, 640, 740 applies compression pressure onto the target body part which can reduce, control or stop bleeding at the wound site as well as reduce, control or stop swelling at the wound site or on portion of the target body part adjacent to the wound site. Thus the inventive pre-formed wound dressing with bladder 100, 200, 300, 400, 500, 600, 700 fills a need of reducing, controlling or stopping bleeding as well as other exudate at a wound site while also applying compression that assists in this reduction, control or stoppage of bleeding as well as reducing, controlling or stopping swelling including edema, lymphedema, CVI, DVT and surgical or trauma caused swelling.

[0090] The bladder 140, 240, 340, 440 540, 640, 740 is activated or inflated when an inflation means (not shown) is connected to the inflation ports 112, 212, 312, 412, 512, 612, 712. The inflation or pressure can be static or intermittent such as a pulsating pressure to a user's limb. Non-limiting examples not shown of the inflations means is a pneumatic pump , hand manual 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 140, 240, 340, 440, 540, 640, 740 so to provide compression in use by the patient or user. Further, a check valve (not shown) or relief valve (not shown) is incorporated with the inflation port 112, 212, 312, 412, 512, 612, 712 to prevent over-inflation once a maximum pressure is detected. Examples of check or relief valves are described in co-owned U.S. Pat No. 7,276,037 and U.S. Pat. No. 7,850,629 and U.S. publication 2022 / 0160574 and U.S. publication 2021 / 0275386, the disclosures of which are incorporated by reference in their entirety. In another embodiment (not shown), the inflation means includes a switch that may have a plurality of integrated umbrella valves so that one umbrella valve is set and closed to maintain the pressure within the bladder 140, 240, 340, 440, 540, 640, 740, while a second umbrella valve would release a certain amount of air or fluid within the bladder 140, 240, 340, 440, 540, 640, 740, 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 inventive 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 140, 240, 340, 440, 540, 640, 740, thus release all pressure and deflate the bladder 140, 240, 340, 440, 540, 640, 740. 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 140, 240, 340, 440, 540, 640, 740 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 140, 240, 340, 440, 540, 640, 740 if the pressure within exceeds 45 mm-Hg and bring the pressure down to 45 mm-Hg (such as when in higlr altitudeor 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 140, 240, 340, 440, 540, 640, 740 and thus release all pressure when activated by the patient so as to deflate the bladder 140, 240, 340, 440, 540, 640, 740 and the inventive pre-formed absorbent wound dressing with bladder 100, 200, 300, 400, 500, 600, 700. By way of another example, the dial or display on the inflation means (not shown) 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 valve occasionally releasing pressure as the pressure increases over the amount or value so that the umbrella valve is activated to release air or fluid within the bladder 140, 240, 340, 440, 540, 640, 740 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 140, 240, 340, 440, 540, 640, 740 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 140, 240, 340, 440, 540, 640, 740 to release pressure completely, one set to always close to maintain air or fluid in the bladder 140, 240, 340, 440, 540, 640, 740 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. The inflation port 112, 212, 312, 412, 512, 612, 712 includes an inventive sealing means connected to the bladder 140, 240, 340, 440, 540, 640, 740 so as to maintain the static compression profile and / or gradient pressure profile when the inflation means is either disconnected from the inflation port 112, 212, 312, 412, 512, 612, 712 or the inflation means stops providing additional inflation or pressure.
