Patient movement monitoring system
First Claim
1. A patient monitoring system for use proximate a doorway with a door, the system comprising:
- a motion detection unit including a motion detection sensor and a first housing supporting the motion detection sensor;
a control unit including control circuitry, at least one light operably coupled with the control circuitry and a second housing supporting the control circuitry and the light, the light indicating one of an alarm condition and a non-alarm condition by selective illumination of the light;
wiring extending between the first housing and the second housing and operably coupling the motion detection sensor with the control circuitry wherein the control circuitry receives signals from the motion detection sensor;
a door sensor assembly securable proximate a door, the door sensor assembly being operably coupled with the control circuit and thereby communicating the open/closed status of the door to the control circuitry; and
wherein the control circuitry is configured to place the light in the alarm condition when the motion detector senses movement and the door sensor assembly detects that the door is closed.

Abstract
A patient monitoring system having a motion detection unit with a sensor and a control unit having control circuitry and at least one light. Wiring extends between the two units and couples a motion sensor with the control circuitry. A door sensor is coupled with the control circuitry. The light is illuminated to provide a silent alarm when motion is detected and the door is closed. Also disclosed is a method of installation that includes attaching a motion detector unit and the control unit to wall surfaces on opposite sides of the door and extending wiring through the doorway to operably couple the two units. The motion sensor may be installed to define a detection zone having a lower boundary which is at least about 18 inches above a patient support surface.

12. Method of installing a patient monitoring system:
-
attaching a first housing to a first wall surface on a first side of a door opening, the first housing supporting a motion detection sensor; attaching a second housing to a second wall surface on an opposite side of the door opening, the second housing supporting control circuitry and at least one light operably coupled with the control circuitry, the light indicating one of an alarm status and a non-alarm status by selective illumination of the light; operably coupling the motion detection sensor with the control circuitry by extending wiring therebetween with the wiring extending through the door opening; mounting a door sensor assembly proximate the door opening and operably coupling the door sensor assembly with the control circuitry; detecting whether the door is open or closed with the door sensor assembly; and placing the light in the alarm condition when the motion detector senses movement and the door sensor assembly detects that the door is closed. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
