(This article was updated September 27, 2022 to reflect the new compliance dates for ISO 80369-7)
The luer is a small-bore connector or fitting for leak-free connections used in intravascular applications or hypodermic applications of medical devices. For example syringes, IV lines, and feeding tubes. The luer gets its name from a 19th-century German medical instrument maker Hermann Wülfing Luer. Luers were standard across the board for the transference of liquid or gas to patients. This means two incompatible devices could be connected. Problem? Absolutely. Solution? Simple, but complicated. Luer ISO 80369-7 compliance and medical device scanning would prove to be the answer and Nel Pretech is helping customers with these new dimensional inspection requirements.
In fact, ISO 80369-7 is years in the making. It takes time to form leadership and develop a coordinated effort to make such a change on a vast scale. Manufacturers couldn’t implement widespread change and conformance on their own. They needed a governing body to guide them. Other solutions like color coded luers did not provide adequate change that was needed. The newly formed standardization is designed to minimize risk of medical misconnections and will affect small bore tubing connectors across the globe. As of December 31, 2019 the FDA no longer accepts new medical device designs for intravascular or hypodermic applications incorporating the luer that do not comply with the ISO 80369-7 standard. In May of 2021 the ISO published a new release of ISO 80369-7 and compliance for existing products has been pushed back from October 2021 to December 17, 2023. After this transition period, declarations of conformity to [Rec# 5-115] will not be accepted.
The luers we are referencing connect to tubes or needles that deliver medicine needed to reach the bloodstream, tubes that need to access the stomach, tubes to deliver gas for breathing, and tubes to access the spine to name just a few. Prior to the ISO standard, the luer or connector was universal; one luer that works with all medical tubing. This was becoming dangerous as more and more devices were being implemented in hospitals and accidental connections of liquid or gas were sometimes being delivered to the wrong area in the patient with catastrophic results. It was becoming clear this was a matter of life or death.
The solution or ISO 80369-7 is to prevent cross connecting by manufacturing enteral connectors or feeding tube connectors that are not compatible with non-enteral connectors. We are seeing an uptick of these parts coming from medical device manufacturers as they implement the new standards in their designs. The new dimensional and functional requirements for luers are specific and Nel PreTech is using computed tomography as a form of medical device scanning to assist manufacturers in their compliance.
