A system, method, and apparatus are disclosed for dressing a wound. The apparatus comprises a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable.

A method of irradiating a wound that includes positioning a wound insertion foam within a wound cavity of a wound and covering the wound insertion foam using a wound sealing layer. The method further includes pumping fluid from the wound cavity using a drain tube sealed within the wound cavity and coupled to a vacuum source, and irradiating the wound using a light diffusing optical fiber that is optically coupled to a therapeutic light source and includes light scattering structures distributed along the light diffusing optical fiber. A portion of the light diffusing optical fiber is positioned within a wound tissue region of the wound, the wound cavity, or both, such that light emitted by the therapeutic light source enters the light diffusing optical fiber, scatters outward from the light diffusing optical fiber, and irradiates the wound tissue region, a wound cavity surface of the wound, or both.

A non-invasive tissue oxygenation system for accelerating the healing of damaged tissue and to promote tissue viability is disclosed herein. The system is comprised of a lightweight portable electrochemical oxygen concentrator, a power management system, microprocessors, memory, a pressure sensing system, an optional temperature monitoring system, oxygen flow rate/oxygen partial pressure monitoring and control system, a display screen and key pad navigation controls as a means of providing continuous variably controlled low dosages of oxygen to a wound site and monitoring the healing process. A kink resistant oxygen delivery tubing, whereby the proximal end is removably connected to the device and the distal end with holes or a flexible, flat, oxygen-permeable tape is positioned at or near the wound bed as a means of applying near 100% pure oxygen to the wound site. The distal end of the tube is in communication with the electrochemical oxygen concentrator and wound monitoring system to communicate oxygen partial pressure and, where appropriate, temperature information. A moisture absorbent dressing is positioned over the distal end of the tubing at the wound site and a reduced moisture vapor permeable dressing system is positioned whereby covering the moisture absorbent dressing, distal end of tubing and wound site creating a restricted or occluded airflow enclosure. The restricted airflow enclosure allows the out-of-the-way control and display unit to provide a controlled hyperoxia and hypoxia wound site for accelerated wound healing.

An apparatus and method for aspirating, irrigating and/or cleansing wounds is provided. The apparatus and method include one or more of the following: simultaneous aspiration and irrigation of the wound, supplying of thermal energy to fluid circulated through the wound; supplying physiologically active agents to the wound; a biodegradable scaffold in contact with the wound bed; and application of stress or flow stress to the wound bed.

An apparatus and method for the controlled acceleration, and/or retardation of the body's inflammatory response comprises a foam pad for insertion into a wound site, a drape covering the foam pad, and a thermal control element configured to be placed proximate the wound site. The foam pad is placed in fluid communication with a vacuum source for promotion of the controlled acceleration or retardation of the body's inflammatory response. The thermal control element has a pair of flexible sheets for receiving a thermally conductive fluid.

This invention relates to use of pharmaceutical compositions in preparing pharmaceuticals for treating diabetic ulcer in limb or on body surface, or in preparing medical dressing. The pharmaceutical compositions consist of (A) 3 to 15% by weight of edible beeswax and (B) 85 to 97% by weight of sesame oil extract of Huangqin, Huanglian, Huangbai, earthworm and poppy capsule, based on the total weight of the pharmaceutical compositions. In the sesame oil extract, each of Huangqin, Huanglian, Huangbai, earthworm and poppy capsule is in an amount of 2 to 10% by weight of dry raw material based on the total weight of sesame oil. This invention also relates to a medical dressing for treating diabetic ulcer and corresponding medicine box enclosing the said dressing.
