Abstract
A patient ambulation motion detector designed to be worn on the body. The detector incorporates a wireless transmitter, a motion sensor switch and a second call switch. It may be enclosed in a plastic case and attached most commonly to the upper anterior chest by a non-allergic double-backed tape.
Claims12
A multi-functional patient detection system comprising:
- a housing including
- a motion sensor automatically sensing movement of a patient's body to an angle of 85°–90° from the horizontal and generating a signal indicative of sensed movement of the patient's body to the angle of 85°–90° from the horizontal,
- a wireless transmitter transmitting a coded identifying signal indicating sensed movement of the patient's body to the angle of 85°–90° from the horizontal generated by the motion sensor, and
- a power supply powering the motion sensor and the wireless transmitter, and
- a receiving station receiving the coded identifying signal from the wireless transmitter.

A patient alert system comprising:
- a housing including
- a motion sensor automatically sensing when a patient's body is at an angle of 85°–90° from the horizontal and generating a signal indicative of sensed movement of the patient's body to the angle of 85°–90° from the horizontal,
- a call button for manual operation by a patient when comfort care is desired and for generating a signal when the call button is actuated,
- a wireless transmitter transmitting a coded identifying signal indicating sensed movement of the patient's body to the angle of 85°–90° from the horizontal generated by the motion sensor and indicating actuation of the call button, and
- a power supply powering the motion sensor, the call button and the wireless transmitter, and
- a receiving station receiving the coded identifying signal from the wireless transmitter.
