Abstract
A system for monitoring a long term care device having a sensor thereon for detecting the presence of a patient on the device includes a microprocessor responsive to a resident program. A first circuit connected to the microprocessor and to the sensor automatically activates operation of the microprocessor to a "monitor" mode upon detection by the sensor of the patient's presence on the device, maintains operation of the microprocessor for a predetermined time period at least equal to a running time of the program and terminates operation of the microprocessor at the expiration of the predetermined time period after detection by the sensor of termination of the patient's presence on the device prior to expiration of the predetermined time period. A second circuit operates the system in response to commands manually applied to the second circuit to deactivate the system to a "hold/reset" mode after activating of the system to the "monitor" mode. The first circuit will also activate the system to the "monitor" mode after the system has been deactivated to the "hold/reset" mode together with subsequent detection by the sensor of termination of the patient's presence on the device and …
