Patient activity monitoring device with multiple sensors
First Claim
1. Apparatus for monitoring movement of a patient in a plurality of ways, comprising:
- a connecting device for alternatively connecting to a plurality of different external sensors connectable to the device;
a data processor coupled to the connecting device and responsive to an external sensor connected to the connecting device for determining whether the patient has moved beyond a limit and for determining whether the external sensor has been improperly disconnected from the connecting device;
an alarm responsive to the data processor for indicating that the patient has moved beyond the limit or that the external sensor has been improperly disconnected; and
a handheld, portable housing for containing the device, data processor and alarm,wherein the data processor is adapted to respond to the plurality of different external sensors.

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.

8. Apparatus for monitoring movement of a patient, comprising:
-
a connecting device for removably connecting to an external movement sensor; a data processor coupled to the connecting device and responsive to the external sensor for determining whether the patient has moved beyond a limit; memory for storing data collected by the data processor; an alarm responsive to the data processor for indicating that the patient has moved beyond the limit; and a portable housing for containing the connecting device, data processor and alarm, the data processor programmed to store in the memory a set of quality assurance data for evaluating the nature of care provided to the patient, the stored data being recoverable by a remote computer operatively connected to the memory, wherein the set of quality assurance data includes the date of the last alarm;
the number of alarms that have occurred since the data was last recovered;
the total time of alarms; and
the longest time from alarm to reset.
