ABSTRACT:
The present invention is directed to a respiratory monitor for monitoring the respiration of a person. The respiratory monitor comprises a detector for detecting the expansion of the chest of the person and an alarm circuit coupled to the detector for producing an alarm signal if the detector does not detect expansion of the chest for a predetermined period of time. Further, a pressure monitor is provided for detecting excessive intrathoracic and/or abdominal pressure. A strap is provided for mounting the respiration detector and pressure monitor on the persons chest or abdomen, the strap including a cushion which compresses when the persons weight is placed thereon. The respiration detector and pressure monitor are mounted on the strap cushion such that when the person lies on his chest, the persons weight is absorbed by the cushion and the detector and monitor are not affected by the persons weight. The respiration detector and pressure monitor can be a normally open mechanical switches which are closed when the persons chest expands and when there is excessive pressure respectively. Further, the band or strap has an annular band having a protruding portion wherein the cushion is fixed to the protruding portion.
