ABSTRACT:
A valve for an arterial monitoring set which continuously supplies a small flow of parenteral liquid, such as normal saline, into a patient's artery while arterial pressure is being continuously monitored. The valve has a flow restrictor providing a normally slow continuous flow rate and an elastically distortable tube which is manually squeezable to provide a fast flush rate. The valve is convenient for one hand operation. A method for assembling the valve by twisting the tube is also disclosed.
