Abstract
A medical pressure transducer includes a reusable component with channels to either side of a reusable diaphragm, and a disposable dome with mounting wings to either side of a disposable diaphragm and slidably receivable in the channels to mount the dome with the diaphragms in confronting relationship. Camming ramps are provided in the channels and on the wings by which to drive the dome diaphragm into the reusable diaphragm. Where the channels are defined behind outer front walls, the outer surface of one is provided with a tab-receiving slot to receive a locking tab associated with dome to lock diaphragms into confronting relationship. The dome includes second wings spaced from the mounting wings to receive the outer front walls. The second wings have finger gripping portions one of which is a locking paddle supporting the lock tab. In alternative embodiments, the dome wings are edges, fixed or resilient, receivable through slots formed in the reusable component.
