Abstract: A patient monitoring system for altering a nurse if a hospital patient gets out of bed at night. The system has a detecting means such as an infrared motion detector for installation on a wall of a hospital room, an activating means responsive to an alert signal from the detecting means to activate a nurse call system, and a signal carrying means to carry the alert signal from the detecting means to the activating means. The signal carrying means comprises a radio transmitter disposed adjacent the detecting means to transmit the alert signal and a receiver to receive the transmitted signal and apply it to the activating means.
