Abstract: An alarm system for an invalid in a hopsital bed includes electric switches placed on top of the side rails and foot rail so that a force applied to any of said switches by a patient results in activation of a warning device. In addition, means is provided for selectively illuminating the hospital bed. Two basic configurations of electric switches are provided, both of which are characterized by the provision of a first switch member which is actuated by light pressure or force, and a second switch member which is actuated by heavier pressure, e.g. when the patient attempts to climb or crawl out of the bed, which could result in injury to the patient due to a fall from the bed to the floor. The switch members when actuated serve to close electric circuits which may sound a buzzer, and/or a call bell, and/or illuminate the bed, so that a nurse or attendant is amply alerted to give attention to the patient.
