ABSTRACT:
A patient ambulation motion detector is intended for attachment to a lateral generally vertical surface of a patient'body. The detector includes a motion sensor switch and a detachment detector switch which are mounted on a circuit board, the circuit board being in turn enclosed within an attachment casing which is attachable to a lateral surface of the patient's body. The motion sensor switch is a mercury switch mounted to the circuit board and having the axis of movement of the mercury contained therein oriented generally parallel to the circuit board so as to be responsive to declination of that portion of the patient's body to which the detector is attached and which declination is indicative of impending ambulation. The detachment detector switch is a spring contact switch which is openable and closable by a plunger acting thereon and sensitive to detachment of the detector from the patient's body. The detector may be wired to a conventional switched nurse call system.
