Patient monitoring system
First Claim
Patent Images
1. A patient monitoring system comprising a pressure sensor, the pressure sensor comprising:
- a sensor housing having an external nozzle defining a nozzle aperture;
a chamber defined within the sensor housing;
the nozzle aperture extending from the external nozzle to the chamber;
a plurality of electrical contacts disposed within the chamber and extending from the chamber to a terminus external to the sensor housing; and
a flexible conductive element disposed within the chamber proximate the plurality of electrical contacts, the flexible conductive element responsive to gas pressure exerted at the external nozzle and translated into the chamber via the nozzle aperture so as to cause the flexible conductive element to bridge the plurality of electrical contacts, and the plurality of electrical contacts configured to conduct current when bridged by the flexible conductive element so as to indicate a gas pressure threshold at the external nozzle.

Abstract
A patient monitoring system includes an inflatable cuff, a gas reservoir containing a compressed gas, and a sensor. When the inflatable cuff is coupled to a wearer, the gas reservoir supplies gas to the inflatable cuff to inflate the inflatable cuff via gas pathways. As the inflatable cuff inflates, a patient monitor can receive blood pressure data from the sensor and use the blood pressure data to determine the blood pressure of the wearer. The patient monitor can also receive blood pressure data during deflation of the inflatable cuff to determine the blood pressure of the wearer.
