A disposable blood pressure transducer system.

Abstract

A unique disposable invasive hemodynamic blood pressure transducer system has been developed. The system consists of a disposable piezoresistive flow-through transducer with twelve-inch pigtail, a reusable extension cable, an electronic interface module and a custom interconnect cable to attach to most monitors. The transducer has Linden Luer fittings and replaces the dome and reusable transducer in monitoring systems. The cost of the transducer is kept low so that it can be disposable through efficient modern, high-volume semiconductor technology and the fact that additional electrical isolation is accomplished in the interface module. Besides providing electrical isolation, the interface module provides a universal output which will accommodate all common AC, DC, and pulsed excitation signals from monitors.
