1. A non-invasive blood pressure monitoring system, comprising:
- an isolated air channel having one or more inlet and exhaust ports to ambient air;
an electronically controlled pump for inflating a cuff applied to a patient limb with air via said air channel; and
a water tight sealed housing containing electronic circuitry for processing signals used in deriving a measurement of patient blood pressure in conjunction with inflating and deflating said cuff, said water tight sealed housing also being sealed from said isolated air channel preventing air and liquid from contacting said electronic circuitry.

Abstract
A non-invasive blood pressure monitoring system, includes an air channel having one or more inlet and exhaust ports to ambient air. An electronically controlled pump inflates and deflates a cuff applied to a patient limb with air via the air channel. A water tight sealed housing containing electronic circuitry for processing signals used in deriving a measurement of patient blood pressure in conjunction with inflating and deflating the cuff. The water tight sealed housing also is sealed from the air channel.
