Hard-wired monitoring system for hospital bed or short term care patients

摘要

A system connectible to an electrical power source for monitoring a short term care device having a sensor thereon for detecting the presence of a patient on the device includes a microprocessor and a plurality of circuits connected to the microprocessor. A first circuit connected to the microprocessor and to the sensor automatically initiates operation of the microprocessor upon detection by the sensor of the patient's presence on the device. A second circuit connected to the microprocessor provides an alarm upon demand by the microprocessor. A third circuit connected to the microprocessor is adapted to be interfaced with a nurse call station for generating signals to the station upon demand by the microprocessor. A fourth circuit connected to the microprocessor programs the system in response to commands manually applied to the fourth circuit. The interrelationship of the resident program with the manual commands permits the system to activate to a "monitor" mode after a predetermined time delay following detection by the sensor of the patient's presence on the device, to deactivate to a "hold/reset" mode after the system has been activated to the "monitor" mode and to trigger to the "alarm" mode when the patient's presence on the device terminates while in the "monitor" mode.
