Apparatus for long term intravenous administration of diluted incompatible multiple medications

Claim 1

An apparatus for diluting, combining, and intravenously injecting a plurality of potentially incompatible substances including medications comprising, in combination: a. a bottle having a penetrable vented stopper and containing a supply of a selected diluent to be withdrawn through the stopper with the bottle inverted; b. an integral spike-manifold structure adapted for placement below said bottle and providing a spike adapted to penetrate said stopper and provide a fluid passage therethrough and communicating with said passage a manifold providing a plurality of discharge ports enabling said diluent to be withdrawn from said bottle through said spike and made available for discharge through each of said ports, said manifold structure having a finger grip formation formed integral therewith and adapted to receive an operator's fingers for installing said spike; c. a plural configuration of tubes, sight chambers, valves and vertically disposed calibrated transparent containers supported below said bottle and spike-manifold structure and providing means whereby various incompatible substances such as medications may be isolated in measured amounts and diluted with the same said diluent while remaining in isolation from each other and at individually controlled rates of flow therethrough, each container having a top inlet port, a tube connection between such inlet port and a respective said manifold discharge port, a bottom outlet port and a bottom tube connected thereto and leading downward therefrom, each bottom tube having in its path a sight chamber and a regulator valve for individually regulating the flow therethrough; d. a mixing-sight chamber having on one upper side a plurality of inlets connected respectively to said bottom tubes for individually receiving and then combining the individually mixed medication-diluent fluids discharged by said containers and on an opposite lower side a discharge port; and e. a fluid injection assembly including a tube having in its path a further sight chamber and regulator valve and said assembly being connected on one end to said mixing-sight chamber discharge port and on the opposite end to a needle for vein injection.
