Abstract
A pneumatic patient bed monitor comprises a hermetically sealed flexible outer shell that contains a porous foam core having a certain volume of air. A flexible tube places the foam core in communication with a pneumatic pressure switch. The tube is hermetically sealed to both the outer shell and the switch. The pressure switch is in a normally open position. When a weight of a patient compresses the foam core, air contained in the foam core flows in a controlled manner into the tube, thereby causing a rise in pressure within the tube and actuating the pressure switch. When the weight of the patient is removed, air flows out of the tube in a controlled manner and back into the foam core, causing a drop in pressure within the tube and de-actuating the pressure switch. The foam core returns to its decompressed state.
