Abstract
A disposable pressure transducer apparatus for monitoring intracompartmental pressures, such as intrauterine and amniotic fluid pressures during childbirth. The apparatus includes a semiconductor pressure transducer mounted on a substrate. The substrate is secured within a flexible boot adapted to allow the pressure pulses present in a uterus to be communicated to the pressure transducer by way of a gel placed in aligned holes provided in both the substrate and the flexible boot. A cable extends from the flexible boot to provide electrical connection between a semiconductor transducer and a monitor/display device. The cable is provided with an internal stiffening stylet to facilitate insertion of the boot into the uterus or other body compartment. The stylet is provided with a vent channel which communicates with the semiconductor transducer and extends along the cable to a hole in the plug on the distal end of the cable, to permit calibration and/or referencing of the transducer to atmospheric pressure.
