Wrist-mounted I. V. administration set
First Claim
1. A multi-lumen, intravenous administration assembly for mounting on a patient'"'"'s arm adjacent a catheter inserted into the patient'"'"'s vein, comprising:
- an integral, relatively rigid infusion body of synthetic resin material and having a plurality of individual tubular elements operably connected with a single outlet head having an outlet end, each of said elements having an input end adapted for connection with a source of liquid to be infused into the patient'"'"'s vein, and a liquid-conveying lumen extending through each tubular element from a corresponding input end to said outlet head,said outlet head having a plurality of liquid delivery passageways extending therethrough, there being one passageway for each of said tubular elements with each passageway being in direct communication only with a corresponding lumen and opening outwardly through said outlet end of the outlet head;
connection structure associated with said outlet head for releasably coupling the outlet end of the head to a catheter inserted in the patient'"'"'s arm vein; and
a mount constructed to support said infusion body on the patient'"'"'s arm with at least the tubular elements being disposed in angular disposition relative to the mount such that the input ends thereof are spaced sufficiently above the adjacent surface of the patient'"'"'s arm to permit ready connection of said input ends of respective tubular elements to sources of liquid, said mount including structure permitting detachable mounting of the infusion body on the patient'"'"'s arm.

Abstract
A patient infusion assembly (10) is provided having a synthetic resin infusion body (12) supported on a flexible adhesive mount (14) allowing the assembly (10) to be secured on a patient'"'"'s body at a desired infusion site. The body (12) includes a plurality of elongated, tubular, substantially rigid infusion elements (16-20) each having an input end (40-44) and connected to a common outlet head (32). The elements (16-20) have individual fluid-conveying lumens (34-38) which communicate with corresponding outlet head passageways (62-66) in order to maintain the separation of respective infusion fluids prior to administration thereof. The outlet head (32) is equipped with a luer connector (60) allowing the ready attachment of a conventional infusion needle (67). Preferably, the elements (16-20) diverge from the connection head (32) with the longitudinal axis of the central element (18) disposed above the axes of the other elements (16, 20). One element (18) has a one-way duckbill-type check valve (54) in the lumen thereof.
