ABSTRACT:
A portable multi-purpose device for monitoring patient movement in a number of different ways. The device includes a data processor programmed to respond to signals from multiple different external sensors that easily connect to the device through a jack in the device housing. If patient movement beyond a limit is sensed, the device generates an alarm for an attendant. To sense the different types of patient movement, one sensor is simply substituted for another. Examples of sensors include tether, door monitoring, and weight sensors. The device protects against unauthorized disabling of the sensors by sounding an alarm if a sensor is unplugged from the device impermissibly. The device provides power to sensors that require power to operate, reducing the need for additional power sources. The device also stores patient data (e.g., number of alarms, time before attendance response, etc.) during a given time period for evaluating a patient's care.
