A flush valve comprising a fluid receiving housing having a first passageway, a fluid discharge housing having a second passageway, and a flow restricting means having a capillary tube defining a primary fluid flow path extending between the first passageway and the second passageway. An elastomeric sealing tube encircles and is biased against the exterior surface of the flow restricting means. A secondary fluid flow path extends from the first passageway to the second passageway between the interior surface of the sealing tube and the exterior surface of the flow restricting means so as to bypass the capillary tube. A connecting plate connects the fluid receiving housing to the fluid discharge housing. Projecting from the connecting plate, receiving housing, and discharge housing are individual pairs of clamping fingers that are longitudinally aligned to form a single U-shaped channel. The U-shaped channel is configured to selectively receive and retain an electrical cable from a blood pressure transducer when the flush valve is attached thereto. To selectively seal closed the secondary fluid flow passageway, an annular ridge projects from the interior surface of the sealing tube and interlocks with a complementary groove formed on the exterior surface of the flow restricting means.
