Abstract

An infusion system for delivery of therapeutic fluids from a remote source into a patient'"'"'s body. The system has an infusion assembly, a rotating pivot joint member, a fluid connector assembly, and a sealing assembly retained within the infusion assembly between the housing of the infusion assembly and the rotating pivot joint member. The seal reduces leakage of fluids. The rotating joint may be pivoted to three distinct positions to allow for emplacement on the patient, delivery of the therapeutic fluid to the patient, and protected, sealed closure of the fluid channels to avoid patient fluid backflow.

Claims

1. A device for delivery of a therapeutic fluid from a remote sensor into a patient'"'"'s body, the device comprising:

an infusion assembly having a generally flat lower surface with a cannula, the cannula defining a cannula axis and depending downward from the lower surface;

a rotating joint assembly having a fluid channel therein, the fluid channel having first channel portion with a first opening in a first portion of the rotating joint assembly and a second channel portion with a second opening in a second portion of the rotating joint assembly, the first and second channel portions angled with respect to one another and connected so that therapeutic fluid may flow between the two openings;

wherein the infusion assembly includes a first coupling member and the rotating joint assembly includes a second coupling member, the two coupling members engaged such that the rotating joint assembly may move from a non-delivery position, where the first channel portion is in a position non-parallel with the flat lower surface of the infusion assembly to a delivery position where the first channel portion lays generally parallel to but spaced above the lower surface of the infusion assembly, the delivery position placing the second opening adjacent the cannula and in fluid communication therewith such that therethrough fluid may flow from the first opening through the second opening of the rotating joint assembly and into the cannula of the infusion assembly; and

wherein the infusion assembly and the rotating joint assembly have cooperating members to lock the rotating joint assembly when the rotating joint assembly is in the delivery position.
