Problems solved by technology

Disconnecting and reconnecting the tubing set is sometimes difficult.
Steel needles, however, can cause irritation and discomfort.
After removing the insertion needle, the first septum may be susceptible to leakage.
This leakage may become more prevalent under pressure, such as when the cannula has an occlusion.
However, if the first septum leaks, the pressure may never reach the threshold, and the pump may continue to deliver insulin.

Embodiment Construction

[0062] FIG. 1 is an overall view of an infusion set 10, in accordance with one embodiment of the invention, for delivery of a fluid to a patient. It may also be used to deliver fluid from a fluid delivery device to a porous medium. In the description, an infusion pump will serve as an example of a fluid delivery device and a human tissue will serve as an example of a porous medium. Fluid may be, for example, a drug, such as insulin. Like numbers in successive figures refer to the same or similar items.

[0063] The infusion set 10 includes a tubing set 11. The tubing set 11 includes tubing 13 that is attached at one end to a hub 12. The hub 12 serves as an interface between the tubing 13 and a pump assembly (not shown). Attached to the other end of the tubing set 11 is an infusion flap 14 that interfaces with a cannula assembly 15.

[0064] The cannula assembly 15 includes a cannula body 17. Attached to the cannula body 17 is a cannula 16, for subcutaneous insertion into the patient. The ...

Abstract

A medical device for delivery of a fluid to a patient from a line terminating in a tubing needle. The medical device includes a cannula assembly for coupling the fluid into a cannula that is inserted into the patient. The cannula assembly has a first locking element disposed in a fixed position with respect to the cannula. Coupling the line to the cannula assembly is an infusion flap. The infusion flap includes a second locking element for engaging the first locking element of the cannula assembly and a lift tab for disconnecting the infusion flap from the cannula assembly. Coupling of the first and second locking elements requires initial mating of the infusion flap and cannula assembly followed by locking through rotation of the infusion flap with respect to the cannula assembly.

Description

[0001] This application claims priority from U.S. provisional patent application serial No. 60 / 291,881, filed May 18, 2001, entitled "Cannula Designs for Insulin Pump Systems." This application is a continuation-in-part of U.S. patent application Ser. No. 10 / 037,614, filed Jan. 4, 2002, entitled "Loading Mechanism for Infusion Pump." Each of these patent applications described in this paragraph is hereby incorporated by reference, in its entirety.TECHNICAL FIELD AND BACKGROUND ART[0002] The present invention relates to a system and method for delivery of a fluid to a patient, and more particularly, to an infusion set for a fluid pump that may be used, for example, to deliver insulin to a patient.[0003] Currently, there are two primary methods of treating diabetes. One method involves taking multiple injections of long acting insulin on a daily basis. The second method is by continuous delivery of short acting insulin to more closely emulate the human pancreas. This may be accomplish...
