A medical pressure transducer (10) includes a reusable component (100) with channels (160,162) to either side of a reusable diaphragm (124), and a disposable dome (200) with mounting wings (230,232) to either side of a disposable diaphragm (224) and slidably receivable in the channels (160,162) to mount the dome (200) with the diaphragms (124,224) in confronting relationship. Stand-off bumps (223) are provided on the wings (230,232) which cooperate with support surfaces (176) on the reusable component (100) in the channel (160 or 162) to keep the dome and reusable diaphragms (224,124) sufficiently spaced apart as to minimize deleterious wear thereon when the dome (200) and reusable component (100) are put together and/or taken apart. Dimples (178) may be provided in the support (176) surface to receive the bumps (233) when the diaphragms are in confronting relationship and no longer need to be spaced sufficiently apart. Camming ramps (181,240) are provided in the channels (100,162) and on the wings (230,232) by which to drive the dome diaphragm (224) into the reusable diaphragm (124). <IMAGE> |
