A wound shield for exudate management may include a conformable frame to circumscribe a wound. The conformable frame may be formed of material for absorbing wound exudate. Exudate absorbing material may also be one of two or more layers of material forming the conformable frame. The layers may be arranged to keep the exudate absorbing layer at some selected distance from a patients skin. Any suitable dressing may be secured over the conformable frame providing separation between the wound and the dressing. The wound frame may provide pressure relief around a wound or pressure sore to permit healing. The conformable frame may be wrapped, in a spiral, around a wound providing an increasing pressure relief by increasing distance from the wound. A conformable frame may be composed of one or more layers of any suitable material and may include adhesive on one or more surfaces to secure the frame to the wound site and or to secure the dressing to the conformable frame. One layer of the two or more layers of material forming the conformable frame may be a wicking or conduit material that draws exudate from the wound and transports the exudate to any suitable media for exudate storage. The exudate storage may be one or more layers of a dressing covering the wound site, or it may be a removable reservoir.

A system and method for detecting, monitoring and analyzing physiological characteristics. Signals from a subject are acquired from a suite of sensors, such as temperature, carbon dioxide, humidity, light, movement, electromagnetic and vibration sensors, in a passive, non-invasive manner. The signals are processed, and physiological characteristics are isolated for analysis. The system and method are to analyze sleep patterns, as well as to prevent bed sores or detect conditions such as illness, restless leg syndrome, periodic leg movement, sleep walking, or sleep apnea. However, numerous other applications of the invention are also disclosed.

The present invention provides a method of treating a leg ulcer comprising contacting the leg ulcer with a collagen biofabric. The leg ulcer may be a venous, arterial, diabetic or decubitus (pressure) ulcer. The invention further provides kits comprising one or more pieces of collagen biofabric for the treatment of a leg ulcer.

A wound shield including a conformable frame to circumscribe a wound and warm water circulating system to maintain a warm environment. Any suitable dressing may be secured over the conformable frame providing separation between the wound and the dressing. The wound frame may provide pressure relief around a wound or pressure sore to permit healing. A conformable frame may be composed of one or more layers of any suitable material and may include adhesive on one or more surfaces to secure the frame to the wound site and or to secure the dressing to the conformable frame.

A decubitis mat includes a plurality of individual cells (16 which are pressurized by air. A polymer sensor / vent structure (20) is mounted on the top surface of each cell and defines a plurality of polymer filled channels (28) and a vent valve (26) which is biased to a closed position. As a body resting on the mat heats the polymer, it undergoes a phase change an expands, causing biasing forces (30) which bias the vent valve to open, permitting air in the cell to be released providing air flow to the body.

Systems and methods for reducing the chance that a patient will develop a bedsore may determine whether a caregiver physically approaches a patient and remains in close physical proximity to a patient for a time sufficient to perform a bedsore prevention action. If a planned bedsore prevention action does not appear to be performed, the systems and methods may alert the patient, the caregiver, or others. A determination may be made as to whether the patient's position has changed in a manner consistent with a bedsore prevention action.
