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. Stand-off bumps are provided on the wings which cooperate with support surfaces on the reusable component in the channel to keep the dome and reusable diaphragms sufficiently spaced apart as to minimize deleterious wear thereon when the dome and reusable component are put together and/or taken apart. Dimples may be provided in the support surface to receive the bumps when the diaphragms are in confronting relationship and no longer need to be spaced sufficiently apart. Camming ramps are provided in the channels and on the wings by which to drive the dome diaphragm into the reusable diaphragm.
