Abstract

A medical pressure transducer (10) including reusable component (100) with channels (160 162) to either side of reusable diaphragm (124), and disposable dome (200) with mounting wings (230, 232) to either side of disposable diaphragm (224). The wings are slidably receivable in the channels to mount dome (200) with the diaphragms (124, 224) in confronting relationship. Camming ramps (180, 240) are provided in channels (160, 162) and on wings (230, 232), respectively, by which to drive dome diaphragm (224) into reusable diaphragm (124) as dome (200) is slidably mounted to reusable component (100). In a preferred embodiment, channels (160, 162) are defined behind outer front walls (164, 162), the outer surface (190) of one of which is provided with tab-receiving slot (192) to receive locking tab (274) associated with dome (200) to lock diaphragms (124, 224) into confronting relationship. The dome includes second wings (250, 252) spaced from the mounting wings to receive the outerfront walls. Second wings (250, 252) have finger gripping portions (264, 265) one of which is a locking paddle (270) supporting lock tab (274).
