Patent number: 6224623Abstract: A weight-bearing apparatus such as a cushion, prosthetic device, or bed mattress includes a support surface having a shaped or sculpted portion that conforms to the shape of a body portion being supported. The shaped portion fits to the body portion, thereby to position the body portion so as to situate one or more weight-bearing parts of the body portion over specific zones of the support surface that are cooled below normal body temperature. The reduced temperature applied to the zones of the support surface removes heat from the weight-bearing areas, thereby reducing the risk of injury to tissue in those areas.Type: GrantFiled: July 14, 2000Date of Patent: May 1, 2001Assignee: Augustine Medical, Inc.Inventors: Scott D. Augustine, Paul Anthony Iaizzo, Ephraim M. Sparrow, Paul Steven Johnson, Randall C. Arnold

Patent number: 6217535Abstract: A non-contact controllable heater wound covering and method 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 are geometries. Another form of active heat is the transfer of a heated gas to the wound covering.Type: GrantFiled: January 27, 2000Date of Patent: April 17, 2001Assignee: Augustine Medical, Inc.Inventor: Scott D.

Patent number: 6143945Abstract: 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.Type: GrantFiled: April 6, 1998Date of Patent: November 7, 2000Assignee: Augustine Medical, Inc.Inventors: Scott D.

Patent number: 6126393Abstract: An air blower unit operates with reduced noise while providing a stream of warmed air. The blower unit includes a housing with an inlet at a first end and an outlet at a second end. A support positions the housing above a support surface such that the inlet points toward the support surface, and the outlet does not point away from the support surface. A rotatable blower creates an airstream by flowing air into the housing through the inlet and out of the housing through the outlet. The outlet is coupled to a delivery conduit having an elbow that absorbs some noise from the blower, and reflects remaining noise downward. The delivery conduit my be connected to a convective thermal blanket, for example. A motor, mechanically linked to the blower, rotates the blower and resides in the housing upstream of the blower. A heater, interposed between the blower and the motor, heats the fluid stream as it passes the heater.Type: GrantFiled: September 8, 1995Date of Patent: October 3, 2000Assignee: Augustine Medical, Inc.Inventor: Randall C.
