Closed multi-fluid delivery system and method
First Claim
1. A multi-fluid delivery system for delivering one or a plurality of fluids, said system comprising:
- a mobile base having a standard mounted thereon;
said standard having mounted thereon, fluid container mounting means, drip detection means, an array of occluder means, a fluid junction having a plurality of input ports and one output port and at least one pumping means;
a primary tubing set comprising a plurality of tubing segments;
at least one fluid container mounted on said fluid container mounting means, said fluid container coupled to one of said fluid junction input ports by said primary tubing set;
said primary tubing set including a drip chamber coupled to said drip detection means and coupled to said fluid junction by a primary tubing set segment coupled through one of said occluder means;
said fluid junction formed as a rigid body including an elongated housing having an internal fluid flow passageway therein opening at both ends defining input and output ports, at least one reusable port communicating with said passageway adapted to have a cannula of a secondary tubing segment of a secondary fluid container and tubing set coupled thereto, said at least one reusable port including septum means and including a plurality of grooves about the inner periphery, of the passageway therein adjacent said septum means to assist in removing air from said fluid junction, and means for mounting said housing to said standard;
said fluid junction coupled through said pumping means to a patient delivery means by a tubing segment connected to said fluid junction output port.

Abstract
An improved multiple fluid delivery system usable for the delivery of intravenous fluids to a patient from a plurality of fluid sources includes flexible tubing members for coupling the sources to a fluid junction member. The fluid junction member, wherein little or no interfluid mixing occurs, is coupled by an output conduit to a controllable pump. Output from the pump, via a further fluid flow conduit, can be coupled to the patient'"'"'s catheter. The system can multiplex a plurality of different fluids. Spaced apart sequences of fluid quanta are injected into the output conduit from the fluid flow junction. The fluids are either mixed, or not, in the output conduit as desired. Operator interaction and control of the system can occur either through a display screen or by means of a bar code sensor. Hard copy records can be provided of fluid flow delivery schedules or other related information.
