ABSTRACT:
A single, disposable differential transducer having a molded plastic body in which there is a pair of chambers separated by a strain gage electronic chip that flexes in accordance with the difference in the pressures between the two chambers. The plastic housing has inlets to allow communication with the chambers and the overall unit is readily manufactured of inexpensive components that allow disposability of the unit when it has been used on a patient. The pressure transducer chambers are isolated from each other such that differing locations of the patient may be sensed for pressure at the same time without the risk of inadvertant cross-contamination.
