A temperature controlled cabinet system and method enables medical items associated with particular temperature ranges to be stored and maintained within the associated temperature ranges in cabinets disposed within ambulances and other medical vehicles. The system includes a temperature sensor for measuring the cabinet interior temperature, a controller assembly for controlling system operation and two head pumps disposed in the cabinet walls to heat or cool the cabinet interior. Alternatively, a single head pump may be utilized to heat or cool the cabinet interior. The controller assembly includes a control console for displaying the actual cabinet temperature and entering a desired temperature range into the system. The heat pumps include a pair of heat sinks disposed about a thermoelectric device (e.g., a Peltier chip) that heats one heat sink, while cooling the other heat sink based on voltage polarity or current flow direction applied to the device. The system controls voltage polarity applied to the thermoelectric device to enable the heat pumps to heat or cool the cabinet interior in response to a comparison of the measured temperature with the desired temperature range. The system utilizes D.C. power from the vehicle electrical system, and may be installed in new cabinets or retrofit into previously disposed cabinets lacking temperature control capability.

A wound dressing garment includes an outer structure layer formed of a pliable material and an interior lining formed of a self-adhesive gel material which serves as a dressing for directly contacting wounds such as burns on a patient. The structure layer provides the overall shape of the garment as well as a framework for supporting the gel layer. The structure layer has at least two edge portions that are securable (i.e., either permanently secured or detachably securable) to each other to provide a partial enclosure suitable for enveloping a portion of the body. The structure layer can include one or more layers of material and can be made of one or more of a variety of materials, such as fabric or elastomeric materials. The self-adhesive, sheet-like gel layer serves as an interior lining of the garment, such that gel layer presents an interior surface for directly contacting the skin of the patient. The gel layer has a soft, tacky texture and readily adheres to the skin but leaves no perceptible residue on the skin when removed. The gel material does not tend to significantly disturb newly formed tissue at the wound site when removed and essentially functions as a synthetic skin over the wound, allowing the wound to heal with a minimum of interaction with the external environment.

A perspiration shield takes the form of a multi-layered sheet that is shaped and sized to be placed between adjacent or opposing skin surfaces, such as under the breast, to prevent and absorb perspiration. The multi-layered sheet has an absorbent layer forming one surface of the shield and a silicone gel layer forming another surface of the shield. The silicone gel layer has a soft, tacky texture and readily adheres to the skin but leaves no perceptible residue on the skin when removed. The silicone gel layer closes the pores of the skin with which the layer is in contact, thereby reducing or preventing perspiration from these pores. The absorbent layer absorbs perspiration from the pores of the skin adjacent and opposing the skin surface to which the silicon gel layer is attached and is formed of a material that readily absorbs moisture. The absorbent layer and the silicone gel layer can be secured to each other via an intervening elastomeric layer, or the absorbent and silicone gel layers can be directly attached to each other. The perspiration shield can have a substantially flat, rectangular shape or an arcuate or contoured shape, and is sufficiently flexible to be bent or molded to a degree to substantially conform to the contours of the skin surface over which the shield is attached.
