ABSTRACT:
Apparatus for protecting a pressure-sensitive transducer in an extracorporeal blood system and for providing a sterile barrier while the apparatus transmits the blood pressure to the pressure-sensitive transducer. The apparatus (34) comprises a housing (40, 42) having first (40) and second (42) generally hemispherical members which symmetrically enclose a generally planar silicone membrane diaphragm (44). The membrane diaphragm (44) has a thickness that is less than 0.040 inch and a diameter that is at least twice as great as the intended total deflection distance. The membrane (44) is centered within the housing (40, 42) and greater pressure on either side of the membrane (44) will cause the membrane (44) to deflect to the other side by stretching.
