<p>Physiological pressure transducers convert an applied pressure (e.g. blood pressure) into an electric signal, which can be displayed by a monitor as a numerical value or continuous waveform. While reusable pressure transducers have been used for a number of years, innovations in solid-state technology have made disposable transducers feasible. In particular, disposable assemblies with transducers which are preferably impedance matched for use with monitors formerly used for reusable transducers, are disclosed. The pressure transducer assembly can be rugged on account of the careful mounting of the transducer diaphragm and integral compensation circuitry. In addition, the geometric configuration of the flow path is uniform such that debubbling of the unit is easy.</p> |
