Hospitals and other healthcare facilities depend on a variety of catheters, tubing and syringes to deliver medications and other substances to patients through vascular, enteral, respiratory, epidural and intrathecal delivery systems. These delivery systems frequently employ fittings called luer connectors to link various system components. Unfortunately, because luer connectors are ubiquitous, easy-to-use, and compatible between different delivery systems, end users can inadvertently connect the incorrect systems together. These misconnections can cause medication or other fluids to be delivered through the wrong route, resulting in serious patient injuries and even death. In an effort to reduce the occurrence of these misconnections, the FDA is in collaboration with the International Organization for Standardization (ISO) and the Association for the Advancement of Medical Instrumentation (AAMI) to develop standards for the noninterconnectability of small bore medical connectors. A joint working group established by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) leads this effort to develop a series of standards for incompatible connectors.
Nordson MEDICAL is well positioned to help you with your tubing connection needs. Our parts are designed, tested, qualified, and documented to be compliant with these new standards. Because Nordson MEDICAL's Value Plastics product line team has participated on the committees developing these standards, you can be assured of a full understanding of the testing and compliance requirements.
Our standard product base has hundreds of different types of luers that can be customized to achieve ISO 80369-7 compliance. Contact us to schedule an appointment with our knowledgeable staff.
General Requirements
The ISO 80369-1 standard provides general requirements to prevent misconnections between small-bore connectors used in various medical devices.
Breathing Systems and Driving Gases
Respiratory applications include connectors designed for low flow, such as flowmeters, nebulizers, nasal cannulae, and ventilators. This application aims to interact with the human body's airways in various modalities.
Enteral
Enteral and gastric applications drive the requirements for these connectors, which have a larger bore than standard luers. The goal of this application is to deliver nutrition directly to the patient when normal eating is not possible.
Urinary (Urethral)
This section of ISO 80369 is yet to be published (as of 2023), but will aim to define the connectors associated with urinary and urethral devices with the purpose of draining urine from the bladder.
Limb Cuff and Blood Pressure
Limb cuff inflation includes blood pressure monitoring and tourniquets, inflating devices external to the human body. These connectors are characterized by smaller bores to not misconnect with other devices that interact with the body.
Neuraxial
Neuraxial applications are designed around anesthesia and spinal fluid procedures. This includes intrathecal injections, epidural infusions, nerve blocks, peripheral infusions, and cerebro-spinal fluid drainage.
Intravascular and Hypodermic
Intended for intravascular (I.V.) and hypodermic applications, the publication supersedes the legacy ISO 594 standard, which defined tapered luer connectors historically.
