ABSTRACT:
A novel disposable pressure transducer apparatus for monitoring human blood pressure. The apparatus includes a semiconductor pressure transducer, a temperature compensation circuit, and light shielding structures mounted on a dielectric substrate. The substrate is secured within a housing adapted to follow the pressure pulses present in a fluid filled catheter to be communicated to the pressure transducer by way of a gel placed in a hole provided in the substrate.
