초록 ▼

An intravenous administration system comprising three separate units adapted for cooperative use for specified intravenous medication. The apparatus comprises a primary I.V. set, a secondary or series I.V. set and a volumetric I.V. set. All sets are made up of modules some of which are common to each set thereby affording substantial savings in stocking of components. The primary I.V. set provides the standard basic I.V. fluid while the volumetric set may be used with the primary to provide introduction of a second medicament through the add-medication site of the primary set. Flow of the medicament from the volumetric set may be volumetrically and periodically controlled. If an added medicament of either compatible or non compatible nature is required, such may be administered by means of the secondary I.V. set which is connected to the primary set. The purpose of the secondary I.V. set is to provide economy in administration of fluids as the secondary I.V. is “piggybacked”into the primary set, and therefore no flow control valve is required for the secondary set.

An intravenous administration system having a plurality of connected intravenous units operating in a cooperative and inter-related manner to Provide controlled administration of several parenteral fluids through a single cannula said system comprising: 1. a primary intravenous set including a. spike means adapted to connect the set to a container of intravenous fluid, conduit means connected to said spike means for conducting fluid from the intravenous fluid container, b. vent means in communication with the conduit means, c. a flowmeter connected to the aforesaid conduit means, d. anti-air lock and anti-air embolism means connected to the outlet end of the flowmeter, e. a flow control assembly connected to the aforesaid anti-air lock and anti-air embolism means, and adaptive means positioned ahead of the flowmeter for receiving the fluid connector of a secondary IV, said means incorporating a check valve for prevention of fluid flow from a primary IV container to a secondary, and a second check valve for prevention of fluid flow from a secondary to the primary, f. a fluid reservoir and administration assembly in communication with the flow control assembly for administering the intravenous fluid to the patient, 2. a volumetric intravenous set including a. spike means adapted to connect the set to a container of intravenous fluid, conduit means connected to said spike, means for conducting intravenous fluid from the intravenous fluid container, b. a valve controlling flow through the conduit means, a vent valve in communication with the conduit means, a volumetric reservoir connected to the aforesaid conduit means, c. a flow meter connected fluidly to the aforesaid volumetric reservoir, d. a flow control assembly connected to the flow meter, and e. a fluid reservoir and administration assembly connected at one end to the flow control assembly and at the other end to the administration assembly of the primary set, and 3. a secondary intravenous set including a. spike means adapted to connect the set to a container of intravenous fluid, conduit means connected to said spike, means for conducting intravenous fluid from the intravenous fluid container, b. anti-air lock and anti-air embolism means connected to the aforesaid conduit means, and c. administration means connected to the anti-air lock and anti-air emolism means, said administration means including a cannula fluidly connected to the primary set above the flow meter whereby intravenous fluid from the secondary set is fed into the primary set for administration thereby. The invention as set forth in claim 18 and wherein the anti-air lock and anti-air embolism means comprises an anti-air lock chamber, a drop tube in communication with the flowmeter outlet and fed into the anti-air lock chamber, a vent valve in communication with said anti-air lock chamber, said chamber having an outlet in its lower position, and a float valve in the anti-air lock chamber.
