초록 ▼

The Rapid Infusion Device is a mechanical pumping system for the rapid delivery of filtered, bubble free, warmed volume to a patient suffering from acute hypovolemia. The principle of operation is one of overcoming resistance mechanically, The flow of fluids is totally regulated by the resistance encountered at the smallest tubing orifice along the infusion pathway. The RID components, assembled as a system, provide the capability for the rapid infusion of filtered, bubble free, and warm volume. The word volume is used to describe the fluid delivered by the device as any desired fluid may be delivered by the device. The RID is composed of two systems, i.e., durable permanent equipment and a disposable unit for one time use. Durable equipment consists of a roller pump, its controls, a permanently mounted heating element and its controls, and a mounting bracket to attach the heating element to the housing of the roller pump. The disposable unit is made of molded plastic cast in two halves. All of the sub-components of the disposable unit are installed at the manufacturing stage and before the two halves are joined, adhered and sealed for liquid integrity.

대표청구항 ▼

A rapid infusion system for rapidly delivering filtered, bubble free, warmed volume to a patient, said rapid infusion device comprising in combination: (a) a pre-assembled unitary disposable unit; and (b) a permanent durable unit; wherein said disposable unit includes all sub-components that will come into contact with the volume infused to the patient including a disposable flexible length of tubing serving as a pumping chamber; wherein said permanent durable unit includes reusable components including driving means and related control means therefor, pump means operably connected to said drive means, heating means for heating the volume, and housing means, said flexible tubing having opposite ends thereof connected to said pre-assembled unitary disposable unit whereby said disposable unit and said length of tubing can be disposed of after use; wherein said housing means supports said pump means, said unitary disposable unit, flexible tubing, said heating means, said drive means, and said related control means whereby a filtered, bubble free warmed volume of predetermined temperature may be infused to a patient at a predetermined flow rate; wherein said preassembled unitary disposable unit further includes a pair of manually operable two-way valves and an adjustable pressure controlled by-pass valve; wherein said adjustable pressure controlled by-pass valve includes a cylindrical housing which encloses a spring loaded ball valve and an adjusting screw which can be adjusted to set the spring bias on said ball valve with respect to a cooperating seat whereby a patient line pressure in excess of the predetermined setting forces said ball to unseat and by-pass a portion of said volume back to said reservoir; and wherein said predetermined setting is in the range of 230 to 300 mm Hg.
