Abstract:
Safety cast compositions for the prevention of thermal injury are provided basically comprising a curable casting material, a flexible substrate coated or impregnated with the casting material and a thermochromic material. Methods for using the safety cast to prevent cast burns in patients in need of immobilizing a body member are also provided.
Abstract:
A non-contact wound covering for covering a wound (54). A peripheral sealing ring (52) is covered by a barrier layer (64) and this assembly is attached to the skin with an adhesive (56). The barrier layer and peripheral sealing ring together define a treatment volume (62) over the wound. The barrier layer may include active and passive heaters and the sealing ring may dispense water to control the humidity of the treatment volume. One form of active heat is the transfer of a heated fluid to the wound covering.
Abstract:
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.
Abstract:
A non-contact controllable heater wound covering having a peripheral sealing ring covered by a layer to which is attached a heater and this assembly is attached to the skin with an adhesive so that the heater is held proximate the wound area in a non-contact position. The layer and peripheral sealing ring together define a treatment volume proximate the wound. The wound covering includes a programmable active heater control and the sealing ring may dispense water to control the humidity of the treatment volume. One form of active heat is an electrical resistive filament in variable geometric shapes providing versatility in application of heat to different types of wounds and wound area geometries. Another form of active heat is the transfer of a heated gas to the wound covering.
Abstract:
A dressing for covering a portion of the anatomical surface of a living being, said dressing being able to adhere to the skin, the mucosa and/or a wound on a portion of a living being, said dressing comprising a substantially water-impervious layer and a skin-friendly adhesive, said water-impervious layer has a pattern of indentation characterised in that the gap of the indentations in the water-impervious layer is diminishing or disappearing when the dressing is moistened.

Abstract:
The device comprises a porous material (11) intended for placing against tissues, for example skin, the material being synthetic or organic and being distinguished by communicating cavities in the form of open pores, interdigitating gaps in particle material or communicating cavities in capillary structures. The material (11) can, by layers, have different cavity qualities and is provided with a dense, sealing shell (10) or layer in which is disposed at least one fluid supply connection (12) and at least one fluid removal connection (13) in spaced apart relationship. Conduits are coupled to the connections (12, 13) and permit the establishment of treatment fluid flow from the supply connection (12), through the cell material (11) in contact with the tissue, to the removal connection (13). Fluid supply can be effected under pressure and/or fluid removal under suction. Electrodes can be disposed in the cell material (11) for sensing the fluid saturation degree, and with the possibility of registering and/or regulating this saturation degree by means of valves. Temperature sensors may be provided in the supply conduit or in the cell material (11) and may be connected to temperature regulator means. Fluid-impervious walls may be provided in the cell material (11) for guiding the treatment fluid flow. The cell material may have one or several replaceable layers.
