Abstract: The present invention relates generally to methods and apparatus for the manufacture of binary switches for use in the medical monitoring field and membrane switches for use in a variety of contexts. More particularly, the instant invention involves the construction, manufacture, and operation of pressure sensitive patient sensors of the sort commonly used in medical settings which can be used, for example, to detect when a patient has exited a chair or a bed. The instant application additionally teaches the construction of membrane switches for use in, for example, electronic instrument control panels. Both the binary switches and membrane switches taught herein are preferably formed from alternating layers of polyester and polyethylene.

Abstract: The present invention relates generally to binary switches for use in the medical monitoring field and to methods for manufacturing same. More particularly, the instant invention involves the construction, manufacture, and operation of pressure sensitive patient monitors of the sort commonly used in medical settings to detect when a patient has, for example, exited a chair or a bed. In accordance with a preferred embodiment of the instant invention, an apparatus for patient monitoring is disclosed herein that contains one or more therein which resiliently collapse in response to weight, thereby completing an electrical circuit and indicating a presence or absence of a patient on the mat. Other preferred embodiments include hermetically sealed mats and methods of manufacturing same.
