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.

Systems and methods for wound area management

Systems and methods for capturing and digitizing an image of a wound and / or a wound trace from a patient and determining there from a degree of change in the characteristics of the wound. A first embodiment includes a transparent / translucent film onto which a dark outline of the wound is traced. The film is fixed to a reference template that provides a geometrically defined reference area. The film / template assembly is imaged with a digital imaging device associated with a handheld digital processor (such as a PDA). The digital image of the template and the wound trace are analyzed to identify the wound tracing and quantify the area within the closed curve. A second embodiment includes imaging the wound site with a reference tag and viewing the image on a display with an associated graphical data input device. A trace of the wound perimeter is made on display with the graphical data input device to establish a data set for the wound perimeter. The data set for the wound trace and the reference tag are analyzed to identify and quantify the wound area. In each embodiment, the system includes a display for providing both a view of the wound trace and the calculated data associated with the wound area.

Pillow for the delivery of blood clotting materials to a wound site

A pillow for supporting a wounded victim at a wound site incorporates a molecular sieve material which is at least partially exposed so that blood flowing from a wounded area supported by the pillow contacts the molecular sieve material to facilitate the clotting of blood flowing from the wound. A removable flexible casing for a pillow incorporates a molecular sieve material capable of providing a clotting function to the blood. An overlay comprising a molecular sieve material can be placed on top of a conventional pillow, on a gurney, or on any other surface. A method of treating a bleeding wound includes providing a pillow having molecular sieve material in particle form retained therein and using the pillow to support a bleeding wound such that blood flowing from the wound comes into contact with the molecular sieve material, thereby causing the blood to coagulate.
