The invention provides a forced air warmer comprising: a chamber having an outlet port; an air heater arranged to heat air within the chamber; an air propagator arranged to propagate heated air from the chamber along a heated air flow path passing through the port; and a temperature sensor provided in the heated air flow path to measure the temperature of heated air propagated along the heated air flow path. The forced air warmer further comprises an air flow conditioner in the heated air flow path downstream of the temperature sensor, the air flow conditioner being arranged to condition air flow at the temperature sensor so as to improve the reliability of temperature measurements made by the temperature sensor. The forced air warmer may be used to supply heated air to an air warming blanket for regulating the temperature of a patient.

Forced air warmer

The invention relates to a device for conveying heated air to a person and comprises an air-permeable inner sheet and an air-impermeable outer sheet which are connected to one another by welds in order to form a panel-like shape in the inflated state. The welds produce a main duct having, viewed at the inlet end and in the non-inflated state, a main duct width. The main duct is delimited by at least one first series of elongate first welded strips, the first intermediate spaces which are in line with one another. The length of each of these first intermediate spaces, viewed in the non-inflated state, is in each case smaller than the main duct width. The length of each first welded strip is at least 15% of the main duct width and at most 80% of the main duct width.
