Problems solved by technology

The end of the male luer fitting does not fully penetrate the slit and the septum deforms without creating a fluid path
In such cases, the connector must be detached and reconnected, which creates an opportunity for contamination of the connector surface and is not clinically recommended
In some cases, the slit will not open fully and the medical staff must replace the infusion set with the failed access port, which consumes the medical staff's time and may cause patient discomfort and additional potential for infection or sympathetic flow. risk

Embodiment Construction

[0023] Bloodstream infections that occur while receiving medical treatment pose a significant risk to patients. Connectors in infusion systems that are exposed to the environment for a period of time prior to connection to a fluid source are a potential source of infection because any bacteria that collect on the connector surface may be directly infected by the fluid flowing through the connector. carried into the bloodstream. Although it is common to use an alcohol wipe to sanitize the outer surface of the connector prior to connecting the fluid source, this step may be ineffective or in some cases may be missed entirely if not performed correctly. One way to ensure that connectors are sterilized prior to use is to provide a convenient means of enabling effective sterilization to be easily accomplished by healthcare personnel.

[0024] When it is not possible to mate a male luer fitting with a female luer access port that has a pre-slit septum that is part of the IV set, de...

Abstract

A sterilizing and pre-opening device for use with a female needleless connector is disclosed. The sterilization and pre-opening device includes a housing including a chamber having a distal opening and configured to fit over a female needleless connector, and a long finger attached to the housing on and configured in the chamber such that when the distal opening of the sterilizing and pre-opening device is arranged in close proximity to the septum and the sterilizing and pre-opening device is advanced in the distal direction, the long finger opens through the female needleless connection the fluid path of the device.

Description

technical field [0001] The present invention relates generally to needle-free connectors in fluid systems, and in particular to infection prevention and preparation for needle-free connectors in intravenous infusion systems. In one embodiment, the present invention describes a needle-free valve and pre-opening device. The goal of preventing infection was considered in formulating at least some of the inventions described herein. Background technique [0002] Many medical facilities have converted to needle-free intravenous (IV) infusion systems to reduce the risk of injury to healthcare workers. Infusion sets that are used as part of a needle-free infusion system often have an access port to allow additional medication to be administered without separating the tubing from the IV pump or IV fluid container. One such needle-free system uses luer fittings to connect fluid components together, including a female luer connector that can incorporate a resilient septum with a sli...
