  • Patent number: 6605051
    Abstract: An apparatus applies heat to tissue from a level that does not contact the tissue, in order to elevate the temperature of the tissue being treated toward normothermia. The apparatus may be attached to the skin of a person to form a treatment volume about the tissue to be treated. A heater, supported at the layer, is held near the tissue to be treated, out of contact with the tissue. The heater is for operating in a near-hyperthermic temperature range in order to treat the tissue. An example of a near-hyperthermic temperature range is 38° C. to 46° C. A controller may include means that cause the heater to operate over a therapeutic sequence, that cycle the heater on and off, that provide selectable average temperature values, that cause the heater to operate over an average temperature range, that cause the heater to operate at an average temperature over a therapy cycle, or that cause the heater to operate at an average temperature over a therapeutic sequence.

  • Patent number: 6585670
    Abstract: 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.

  • Patent number: 6570050
    Abstract: 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.

  • Patent number: 6569189
    Abstract: 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.

  • Patent number: 6558413
    Abstract: 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.

  • Patent number: 6544283
    Abstract: An inflatable thermal blanket includes an inflatable covering with a head end, a foot end, two edges, an undersurface and a drape. The inflatable covering is inflated through an inlet at the foot end by a thermally-controlled inflating medium. An aperture array on the undersurface of the inflatable covering exhausts the thermally-controlled inflating medium from the inflatable covering. An uninflatable section is provided at an end of the inflatable covering to provide the drape. When inflated, the inflatable thermal blanket provides a bath of thermally-controlled inflating medium through the apertures. When inflated, the inflatable thermal blanket covers a patient, while the drape retains heat from the inflating medium to contribute to patient warming and to insulate the bare skin of the patient from excessive conductive heat from a hose connected to the inlet. The drape preferably is a foot drape formed from an uninflatable extension of the inflatable covering at the foot end.

  • Patent number: 6541740
    Abstract: A substantially constant load impedance electrical heater has been provided. The heater is comprised of two sections, a first heater and a second heater. The first heater is continuously “on” to provide the bulk of the heat. A second heater is selectively engaged to provide slightly more heat to the medium, heating the medium to the desired temperature. The output temperature of the heated medium is maintained by controlling the duty cycle of the second heater. More drastic changes in temperature are accomplished by changing the power continuously dissipated by the first heater. The greatest heating control is obtained by defining the first and second heaters as subsets from a bank of selectable heater elements. A method of minimizing fluctuations in the loading of a high-wattage electrical device is also provided.

  • Patent number: 6535689
    Abstract: An intravenous (IV) fluid warming system with a removable heat exchanger includes a presence detector. The system is for warming an IV fluid before infusion into a body. The system includes a warming unit for warming the IV fluid and an inlet slot for receiving a heat exchanger, preferably embodied as a cassette . The heat exchanger is sized to fit into the inlet slot of the warming unit. The heat exchanger has a heat exchanger membrane with an internal fluid pathway that is in fluid communication with a fluid inlet port and a fluid outlet port. While the heat exchanger is in the warming unit, the IV fluid flows through the internal fluid pathway of the heat exchanger, warming the fluid. A heat exchanger presence detector is part of the warming system. The presence detector detects the presence of the heat exchanger when it is received in the warming unit. The presence detector enables the heating operation of the warming unit when the presence of the heat exchanger is sensed.

  • Patent number: 6519964
    Abstract: Cooling devices are provided to reduce a person's temperature by evaporative, convective, and/or conductive cooling. One such device maximizes evaporative cooling by aiding the flow of air to the person and the removal of vapor-laden air from the person. An upper sheet and a base sheet are adhered to define numerous elongated, parallel, inflatable cooling chambers separated by flat connecting membranes. Ventilating cross-members interconnect the cooling chambers. Air enters the chambers through an inlet, exits the chambers toward the person through air permeable regions of the base sheet. Air heated by the person's body exits the device upward through evaporation openings in the connecting membranes. The foregoing device, or different variations thereof, may be modified for use in conductive cooling by adding an absorbent sheet beneath the base sheet, or substituting the absorbent sheet for the base sheet itself.
