Method of flushing a medical fluid

摘要

A method of flushing a medical liquid into a system that is continuously monitoring a patient's blood pressure. A parenteral liquid, such as saline, is flushed through a valve that has an elastic tube encasing a flow restrictor having a flow passage. The method includes passing the liquid through the flow passage at a predetermined rate, squeezing the tube to temporarily create an enlarged flush passage, and then releasing the tube to seal off the flush passage to force liquid through only the flow passage of the restrictor. This method of flushing can be conveniently carried out with one hand.
