    摘要: A bandage for autolytic debridement includes a fluid-impermeable enclosure having a sidewall forming a margin defining an opening, and a skin-facing surface that surrounds the opening. An attachment means is disposed on the skin-facing to attach the enclosure to the skin, with the margin extending outside of and surrounding at least the bed of a wound. When the enclosure is attached to the skin it creates a closed, fluid-impermeable chamber over a wound, substantially without contacting the wound. The bandage includes a fluid absorbent material disposed in the fluid-impermeable enclosure at or near the continuous margin, and out of the opening. The fluid absorbent material is thus positioned to receive and retain exudated fluid that originates in the wound, thereby by promoting autolytic debridement. The closed, fluid-impermeable chamber maintains a near-100% humid atmosphere about the wound, thereby promoting healing of the wound. The humid atmosphere and the structure of the bandage tend to maintain the temperature of the atmosphere about the wound at or near a normothermic level in the range of about 36° C. to about 38° C., thereby maintaining physiologic processes that drive autolytic debridement and wound healing.

    摘要: A wound treatment apparatus is provided which includes a thermally conductive bandage, a heater in contact with the bandage over a wound treatment area, and an adhesive attachment device for maintaining thermally conductive contact between the heater and the bandage. The bandage and heater together have a low profile so as to be convenient for the patient and are flexible so as to conform to the shape of the wound and to the contours of the skin surrounding the wound. The attachment device is fashioned so as to have less pull strength than an adhesive holding the bandage to the person's body so that the heater can be easily removed without disturbing the attachment of the bandage to the person's body. The bandage is provided with a polymeric film for maintaining moisture at the wound site as well as enhancing the utility of the attachment device.

    摘要: A core temperature sensor and a method of using such a sensor to non-invasively measure a temperature of a core thermal compartment of a human body or other mammals. A heater of the core temperature sensor heats a peripheral area to a temperature greater than the core temperature. A skin temperature sensor of the core temperature sensor monitors a cooling of the peripheral area to determine the core temperature.

    摘要: A tissue treatment apparatus includes a bandage that is transparent to, or transmissive of, energy in a predetermined range of the infrared (IR) portion of the electromagnetic spectrum. The bandage includes a layer that acts as a bandpass filter, permitting IR radiation in the range of wavelengths between 3 and 30 &mgr;m to pass through the bandage to tissue against which the bandage is disposed. A heater is used to generate heat, including IR radiation, and an attachment device retains the heater over or on the bandpass bandage layer. The bandage and heater together have a low profile so as to be convenient for a patient, and are flexible so as to conform to the shape of a wound and to contours of the skin near the wound. The bandage is provided with an adhesive pattern for maintaining moisture at the wound site. The heater may maintain a normothermic condition at subdermal regions of the wound treatment area. A controller may be provided for cycling the temperature of the heater in order to maintain the normothermic condition.

    摘要: An inflatable cover is constructed with a base sheet to which is attached an overlaying material sheet in order to form an inflatable structure. There is an opening to admit warmed air into the inflatable structure. A plurality of apertures open through the base sheet, into the inflatable structure for the purpose of exhausting warmed air therefrom, through the base sheet. The plurality of apertures vary in density toward an edge of the base sheet for the purpose of establishing various temperature profiles with respect to the inflatable cover. In a particular embodiment, the density of the apertures increases toward the edges of the base sheet, from the center of the inflatable cover.

    摘要: A thermal blanket includes an inflatable covering with a head end, a foot end, two edges and an undersurface. The covering is inflated through an inlet at the foot end by a thermally-controlled inflating medium. An aperture array on the undersurface of the covering exhausts the thermally-controlled inflating medium from the covering. Exhaust port openings are provided at the edges of the covering to vent the inflating medium, which enhances circulation of the thermally-controlled medium through the cover. An uninflatable section is provided at the head end, together with an absorbent bib attached to the covering, adjacent the uninflatable section. When inflated, the thermal blanket self-erects and provides a bath of thermally-controlled inflating medium to the interior of the erected structure. The enhanced circulation of the medium through the covers maintains a relatively high average temperature under the blanket and a relatively uniform distribution of temperature in the inflating medium which is exhausted through the apertures into the structure's interior. When the structure covers a patient, the uninflatable section provides a relatively unobstructed view of the patient's face, while the absorbent bib maintains a relatively sanitary environment in the area beneath the patient's head.
