A heating system for providing heat to a draped basin containing liquid above the drape. In addition to having at least one temperature sensor that controls a flow of electricity to the heating element, the system has at least one air gap detector in thermal contact with the heating element. Each air gap detector responding to a temperature above a high setpoint temperature for that air gap detector by interrupting the flow of electricity until detecting that the temperature has fallen below a reset setpoint temperature for that air gap detector so that an air gap in proximity to the one of the air gap detectors is prevented from causing a severe temperature excursion in a portion of the draped basin. Thus, the drape is protected from a local temperature excursion.

Air gap detectors in heating system for draped basin

Drapes for covering fluid heating devices having basins. Some drapes have a set of at least one positioning component trapped between the drape basin layer and the drape device layer by a set of bonds. The positioning component aligns the drape with the basin bottom. Optionally, the drape may have a low-slip film for basin contact and a non-slip film for at least a portion of the drape beyond the basin. Alternatively, a single layer drape may have a set of at least one positioning component bonded to the drape. Some drapes have basin-shaped sterile vented barrier with vents to allow the sterile vented barrier to be inserted into the basin and to vent air out of the basin. The heating system for the fluid heating device may interrupt electricity provided to a heating element when a temperature sensed at an air gap detector exceeds a high temperature setpoint.
