Warming Units, Patient, Conductive Layer
Definition : Patient warming units comprised of a heat conducting layer (e.g., carbon polymer) placed above a flexible (e.g., viscoelastic foam) pad that conducts heat supplied by a low voltage power source (either mains or rechargeable battery). The pad can come in various sizes and is placed under or over the patient as a mattress or blanket and can mold to the shape of the patient's body to evenly heat the patient. A control unit is used to maintain the pads at the user-selected temperature. Temperature is monitored by a thermistor built into the pads and this signal is used to allow control of the power supplied. The control unit uses a transformer to convert the mains input to a very low voltage (usually 24 volts alternating current), and regulates this to achieve and maintain the required heating. A thermal cut-out is also integrated into the mattress or blanket to prevent over-heating of the patient. Conductive layer patient warming units are used in emergency rooms, patient transport, rescue and military applications, perioperative areas, intensive care units, and home care settings. Dedicated infant-sized conductive layer warming units are also available for use in neonatal care settings.
