Abstract:
A blood-pressure transducer assembly insertable into a system adapted to monitor the blood pressure of a patient while the patient is being intravenously supplied with a saline or other liquid derived from a source coupled by a supply line to a catheter implanted in the patient, said assembly comprising:A. a plurality of sub-assemblies housed within a common casing, said casing having an inlet port to be coupled to an upstream section of the supply line, and an outlet port to be coupled to a downs section thereof whereby the liquid flows through the assembly and from there into the blood stream to create within the assembly a column of liquid whose pressure varies as a function of blood pressure, and B. a transducer in one of the sub-assemblies in contact with the column to sense the pressure thereof to produce an electrical signal in accordance with the sensed pressure, said signal being conveyed to an external monitor which displays the waveform thereof.
