Abstract: To monitor a patient, a pressure sensor is placed under the patient. The pressure pad includes a normally open switch having first and second contacts. Pressure on the pad over a preset amount arms the switch and release of the pressure causes an alarm and/or a message to be announced. The closing of the first and second contacts requires bending one of the first and second contacts over a spacing means, wherein the spacing means includes at least one spacing member that is at least one-eighth inch in height between the first and second contacts. In this manner, the contacts are held apart until the resilient spacing member is forced shut. The pressure pad is low cost and can be disposable.

Abstract: To monitor a patient, an alligator clip is fastened to the patient by a cord having a length of between five inches and five feet. The other end of the cord is connected to a switch which is activated when the patient moves beyond the length of the cord to cause a message to be announced. A disposable pressure pad is located under the patient and armed by the application of weight to the pad. Upon removal of the weight the alarm is given.
