Abstract
A unitary blood-pressure transducer assembly for inclusion in a system adapted to monitor the blood pressure of a patient while the patient is being supplied through a supply line leading to a catheter implanted in a blood vessel with a saline liquid. The assembly includes free sub-assemblies housed within a common casing and having an inlet port to be coupled to the upstream section of the line and an outlet port to be coupled to the downstream section whereby the liquid flows through the assembly. Intermediate the ports is a first sub-assembly having a transducer that senses the pressure of a column of liquid developed within the assembly, whose pressure varies as a function of the pressure of the blood streaming through the blood vessel. Adjacent the inlet port is a second sub-assembly that includes a fast-flush valve to purge air bubbles from the assembly and a flow restrictor to maintain liquid flow at a low flow rate. The third sub-assembly which is adjacent the outlet port includes a stopcock to selectively direct flow to allow for priming and zeroing of the system as well as blood sampling.
