  • Disposable mass flow transducer
    Patent number: 6003386
    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 isolasted 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.
    Type: Grant
    Filed: July 8, 1998
    Date of Patent: December 21, 1999
    Assignee: Becton, Dickinson and Company
    Inventors: Robert Guthrie, John Yan, Rene Luigies
