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.
