Adapter for use with a multi-port control valve used in blood sampling, blood pressure measurement systems

Abstract:

Disclosed is an adapter for use with a multi-port control valve that is used in a blood sampling, blood pressure monitoring system that includes a sampling site, a pressure transducer, and a reservoir. The multi-port control valve includes a partition and a rotatable valve member that rotates around to one of a reservoir port, a sampling site port, or a pressure transducer port to block fluid communication. The adapter comprises: a partition to define an input fluid path and an output fluid path, wherein the partition of the adapter mates with the partition of the multi-port control valve and a partition of the reservoir, in which, the partition in the adapter mates with the partition in the reservoir such that a fluid circuit is created from the multi-port control valve, through the adapter, and through the reservoir, and back to the multi-port control valve.
