  • Patent number: 4464179
    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.
    Type: Grant
    Filed: November 26, 1982

  • Patent number: 4267834
    Abstract: A system for continuously administering parenteral liquid, such as normal saline, to a patient while blood pressure fluctuations are continuously monitored. The system includes a flushing valve with a manually squeezable and distortable elastic tube surrounding a flow restrictor. The flushing valve is connected through a flexible tube segment to a T-connector of the system to provide for convenient one hand flexible operation. The flushing valve, flexible tube segment, and T-connector are joined as a unit for assembling into the system.

  • Patent number: 4267833
    Abstract: 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.
