AI Technical Summary

Benefits of technology

Facilitates easy and effective disinfection of the access port lumen, ensuring aseptic conditions for prolonged periods without additional equipment, significantly enhancing disinfection reliability and persistence compared to conventional swabbing methods.

Problems solved by technology

As a problem with these designs, when the access port is opened, sterility of course is lost in the lumen of the access port and any barriers, valves or mechanisms within the flow pathway of the port, and the port should be resterilized or disinfected if it is to be reused.

Embodiment Construction

[0007]In accordance with this invention, a closure for a tubular access port in a medical fluid flow line or other container comprises: a removable, tubular cap for enclosing the tubular access port. The cap has a closed end wall, with or without a male member attached to its inner face, while typically the end wall's outer face, in turn, carries an outwardly extending poker to facilitate the pushing of an antiseptic-containing material, typically an alcohol “prep pad”, into a lumen of the access port to disinfect at least that portion of such lumen that will mate with the connector of a connecting device, for example, a syringe. Preferably, the entire recessed lumen or flow path of the access port receives disinfectant including portions proximal to any barrier or valve mechanisms that are recessed in the lumen and may become contaminated with use. The poker has an outer diameter that is less than the inner diameter of the access port, to provide space in the access port lumen for ...

Abstract

A closure for a tubular access port in a medical fluid flow line or other container comprises a removable cap for enclosing and sealing the tubular access port. The cap has a closed end wall. The end wall carries an extending poker to facilitate the pushing of an antiseptic-carrying material into a lumen of the access port. The poker has an outer diameter that is less than the inner diameter of the access port. A method of using the poker is also described.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application is a divisional of prior application Ser. No. 11 / 247,931, filed Oct. 11, 2005.BACKGROUND OF THE INVENTION[0002]Tubular access ports are used in medical fluid flow lines and other medical fluid containers such as blood and parenteral solution bags, syringe chambers for administration of liquids, and various tube sets such as hemodialysis arterial and venous sets, plus other extracorporeal blood flow sets, and parenteral solution administration sets. The tubular portion of the access port is designed to receive a mating connector of another device which fits within the lumen of the tubular portion. To preserve sterility prior to use, the tubular access port may have a closure of conventional design, typically a removable, tubular cap comprising an end wall covering the opening of the lumen, a tubular wall fitting around the outer portion of said tubular portion and, also, typically, a male member attached to the inner...
