Control device for a hospital bed |
摘要 |
A sensor is provided in a hospital bed having a bed-mat made of movable particles. This sensor is to detect an excessive bead temperature in the case of a controller malfunction and to control the operation of a cooler. In the sensor, the circuit is so designed that an air compressor runs intermittently with the aid of timers while the sensor performs its functions at a temperature above the predetermined temperature level. The sensor also enables the compressor to run again when the temperature of the mat lowers to a level where a normal operation is possible to assure temperature control of the bed-mat even in the case of controller malfunctions.
