ISO 80369: Greater Safety for Small-Bore Connections in Medical Technology

The ISO 80369 series of standards was developed to reduce the risk of misconnections between medical tubing and connector systems, thereby improving patient safety. It applies to so-called small-bore connectors, meaning connections for liquids and gases in patient-related medical applications. The aim of the ISO 80369 standards is to design connector geometries for different therapy areas in such a way that they are not compatible with each other if they are not intended to be connected.

This can be particularly important in clinical environments where multiple lines, connectors, and medical systems are used simultaneously. The ISO 80369 series provides a clear framework for application-specific connector systems across various medical fields.

Overview of the ISO 80369 Series

The basic requirements are described in ISO 80369-1. This part defines the general interface requirements and specifies the application areas covered by the series, including respiratory, enteral, neural, and intravascular or hypodermic applications.

Building on this, further parts of the standard series define requirements for specific medical application areas:

ISO 80369-2 covers connectors for respiratory applications. The standard distinguishes between two connector types for different pressure ranges.

ISO 80369-3 defines requirements for enteral applications, such as feeding systems, enteral syringes, sets, and access ports.

IEC 80369-5 applies to connectors for limb cuff inflation, for example in blood pressure cuffs.

ISO 80369-6 specifies connectors for neural applications, including use cases such as regional anesthesia or the monitoring and drainage of cerebrospinal fluid.

ISO 80369-7 describes connectors for intravascular and hypodermic applications and is today’s reference for Luer-based connections in this area.

ISO 80369-20 contains the common test methods used to evaluate performance requirements within the standard series.

What Does This Mean for Manufacturers and Development Projects?

For companies developing, assembling, or sourcing components, sets, or systems with small-bore connections, ISO 80369 can have a direct impact on design, component selection, and validation. This is especially relevant when traditional Luer connections are used in applications for which an application-specific connector is now required.

Depending on the application, the transition may mean that existing connector solutions need to be adapted, new components integrated, or testing and validation requirements reassessed. What matters is not only the standard itself, but also how it affects the specific product, the intended application, and the regulatory documentation.

MedNet as a Partner for Selecting Suitable Connector Solutions

MedNet supports manufacturers in identifying suitable components and connection solutions for medical applications and aligning them with project-specific requirements. Depending on the area of use, this includes both standard components and customized solutions for applications where safety, compatibility, and clear assignment of the connector system are particularly important.
