Wound treatment employing reduced pressure
InactiveUS7216651B2Reduce pressureIncreased formationDiagnosticsRespiratory masksWound siteVacuum pump
A method of treating tissue damage comprises applying a negative pressure to a wound sufficient in time and magnitude to promote tissue migration and thus facilitate closure of the wound. The method is applicable to wounds, burns, infected wounds, and live tissue attachments. A wound treatment apparatus is provided in which a fluid impermeable wound cover is sealed over a wound site. A screen in the form of an open-cell foam screen or a rigid porous screen is placed beneath the wound cover over the wound. A vacuum pump supplies suction within the wound cover over the treatment site.

Gradient wound treatment system and method
A wound therapy and tissue management system utilizes fluid differentiation. Fluid is differentiated by establishing a gradient within the system. A gradient can be established with matter or energy. Patient interfaces for establishing, maintaining and varying one or more gradients include transfer elements with first and second zones having different flow coefficients. The transfer elements exchange fluid with a patient, generally through a wound site, and with external components of the system. Osmotic solution gradients are controlled by a methodology involving the present invention for extracting solutions, which can include toxins, from patients and for introducing fluids and sumping air to wound sites.

Insulator-conductor device for maintaining a wound near normal body temperature
InactiveUS6613953B1Low thermal conductivityMinimizes thermal conductionFinger bandagesPlastersHeat lossesHeat energy
A wound treatment device which fits over standard bandages and covers both the wound area itself and major portions of the surrounding area of healthy skin of an extremity such as a leg, arm, or foot. The wound treatment device maintains the wound near normal body temperature (37° C.) by conserving and redistributing the body's own heat energy using a high efficiency thermal insulator to minimize heat loss from the wound and surrounding skin area and a high efficiency thermal conductor for distributing heat from the surrounding skin to the wound area. The wound treatment device avoids potential problems associated with external heat sources and provides for an ideal physiological environment for wound healing. The wound treatment device can be worn by the patient for extended periods of time during their regular daily routine without constant medical supervision. The wound treatment device can also store extra thermal energy generated by physical activity such as walking, cleaning, or bicycling.
