ABSTRACT:
An elongated air inflated flexible bag is placed below the mattress of a hospital or nursing home bed and connected to a pressure actuated electrical switch signal at a remote attendant's station. The switch is a normally closed low pressure switch that remains open for as long as a patient's weight maintains an air pressure greater than the preset actuating pressure of the switch and closes when the patient's weight is removed and the pressure in the bag is thereby lowered, energizing a signal at the attendant's station.
