Intravenous administration system
First Claim
1. 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 includinga. 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.

Abstract
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.
