Abstract: Cooling pads, mattresses, and limb-comforming sleeves reduce a person's temperature by evaporative and/or conducting cooling. An open cell foam pad defines an internal air flow passages proceeding according to serpentine or other desired routing. The pad is wetted, and a blower circulates air through the air flow passage and evaporatively cools the pad by removing warm water vapor. By contacting the cooled structure, the person is conductively cooled. The pad also employs evaporative cooling if water is permitted to seep from the foam pad onto the person's skin and subsequently evaporate. Another cooling device is a multi-layer evaporative cooling mattress. The mattress comprises an open cell foam structure having a person-receiving side and a base side. At the person-receiving side lies an absorbent layer with internal liquid delivery lines, and optionally having an outer film applied thereto.

Abstract: An apparatus and method for cleaning the objective lens of a laparoscope, endoscope, or coeloscope during surgery and also removing the solution and debris during and after the cleaning. The result is obtained by using a rigid hollow split sheath for the scope. The split sheath has two separate channels. One channel is for irrigation and the cleaning fluid flows through this channel to be directed onto the lens. The other channel is for suction to remove the solution and debris during and after the cleaning. Control buttons located at the operator's end activate the irrigation and suction functions. The control buttons for irrigation and suction are fabricated into an existing valve type device which can regulate either of these functions. In addition, two ports, one for irrigation and one for suction emerge from the operator's end to connect to the appropriate tubing for irrigation and suction.
