초록 ▼

A closed-system, combination infusion and flush set which enables safe administration of both medicaments and flush solutions to a patient with great accuracy using conventional large volume parenteral bags. The administration set comprises a specially designed rotatable valve member for controlling fluid flow through the set and includes a stop post which positively blocks rotation of the valve member to a position that permits the flow of flush solution toward the patient.

대표청구항 ▼

An apparatus for controlling the flow of fluids from a fluid container toward a patient, comprising: (a) a first fluid conduit having an inlet and an outlet, said outlet being interconnectable with the patient; (b) flow control means for controlling fluid flow between the fluid container and said outlet of said first fluid conduit, said flow control means comprising: (i) a valve body having an internal chamber, first and second fluid inlets and a fluid outlet, said fluid outlet being connected to said inlet of said first fluid conduit said valve body also having first, second and third circumferentially spaced, outwardly extending fingers; (ii) valve means disposed within said valve body for controlling fluid flow into said first fluid inlet and for selectively controlling fluid flow between said first fluid inlet and said second fluid inlet and between said second fluid inlet and said fluid outlet, said valve means comprising a valve member rotatable within said internal chamber of said valve body, said valve member having first, second, and third circumferentially spaced fluid flow passageways, said valve member being rotatable between a first position permitting fluid flow between said first and second inlet of said valve body and said outlet thereof via said first and third fluid flow passageways, said third finger circumferentially aligned with said third passageway; and (iii) stop means for positively preventing fluid flow between said first fluid inlet and said fluid outlet, said stop means comprising and outwardly projecting stop post connected to said valve body for engagement with said third finger of said gripping means to prevent alignment thereof with said first inlet of said valve body; and (c) a second fluid conduit having an inlet interconnectable with the fluid container and an outlet connected to said first fluid inlet of said valve.
