Benefits of technology

The present invention is an access connector for accessing patient fluid lines. It has a unique design that reduces movement between the housing and the septum, which keeps the connector performing at its best. This invention provides a reliable and durable access to patient fluid lines.

Problems solved by technology

If the septum is not properly bonded to the housing, the septum will pull out, or, as the taper slips off the septum, the septum snaps back into the housing causing fluids to spatter.

Embodiment Construction

[0026]FIGS. 1A-1C show components of a representative embodiment of access connector 10a, which housing 12 and septum assembly 14. Housing 12 includes body 16 with tower 18 and thread 20, base 22 and fluid line port 24. Septum assembly 14 includes septum 26 with slit 28 and frame 30.

[0027]Housing 12 and frame 30 are typically made of thermoplastic material such as polycarbonate, polyesters and polycarbonate / polyester blends. Septum 26 can be made from silicone or polyisoprene. A suitable material is adhesive grade liquid silicone rubber. Housing 12, frame 30 and septum 26 may be fabricated from other materials as long as septum 26 is flexible, while housing 12 and frame 30 are relatively rigid.

[0028]Frame 30 in FIGS. 1A-1C is a thermoplastic ring that surrounds the top of septum 26. Septum assembly 14 is integrally formed by an injection molding process such as insert molding or multi-shot molding. As a result, septum 26 and frame 30 are bonded together as a part of the molding proc...

Abstract

An access device provides needleless access to patient fluid lines such as intravascular catheters. A septum assembly of the access device is formed from a frame integrally molded with a septum and provides access for a tubular portion, such as a male luer taper of a syringe, of a medical device. The frame of the septum assembly is bonded to the housing of the device, which minimizes axial and rotational movement between the septum and the housing, so that the access device properly operates through multiple uses.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 11 / 281,526 which was filed with the U.S. Patent and Trademark Office on Nov. 17, 2005.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a connector for accessing patient fluid lines. In particular, the present invention is an access connector that may be opened by a tubular portion of a medical device, such as a male luer taper of a syringe.[0004]2. Description of the Related Art[0005]In the course of treating patients, clinicians are continually transferring patient fluids between various containers and intravascular (IV) lines or through IV catheters. Transfer of these fluids is preferably through a closed system to prevent microbes from entering the system and causing infections in the patients. Many of these closed systems have relied on the use of a needle to penetrate a rubber or silicone septum to gain access to the f...
