MEDICATION INFUSION SET

摘要

An infusion set is provided for use in delivering fluid through a cannula, which is housed on a cannula housing, to a selected subcutaneous infusion site on a patient. The fluid is generally a medication, e.g., insulin. The cannula is in fluid communication with a fluid passageway surrounded by a projection on the cannula housing that includes one or more rail-like extensions acting as guides. A connector connects the cannula housing to a fluid delivery system, e.g., an infusion pump. The connector includes a needle, one or more guide arms that slide over the rail-like extensions to guide the needle into the self-sealing septum, and one or more locking arms, with barbs at the end, to connect with corresponding recesses in the cannula housing. An introducer having one or more similar guide arms and locking arms, and a longer needle, may be used to insert the cannula into the patient.

1. A connector device to deliver fluid from a fluid delivery device to a body of a user, the connector device comprising:
separate first and second guide arms having no physical connection therebetween, each of the separate first and second guide arms having opposing inner and outer longitudinal sides, wherein, for each guide arm, the outer longitudinal side is flat along substantially the entire length thereof and the inner longitudinal side has an arcuate profile along substantially the entire length thereof, said inner side of the first guide arm facing the inner side of the second guide arm; and a longitudinally-extending connecting needle that is parallel to said guide arms and is disposed laterally spaced apart from, and in-between, said first and second guide arms, wherein the needle has a distal tip and the guide arms have respective distal ends, and the distal ends of the first and second guide arms extend beyond the needle's distal tip.
