What are small bore Connectors?

Many different types of medical devices incorporate small-bore connectors. Small-bore connectors are parts used to connect medical devices such as tubing, syringes, and other accessories that deliver fluids and gases for patient care. Small-bore refers to the small size of the diameter opening (less than 8.5 millimeters) of the connector.

What is Medical Device Misconnection?

Medical device misconnections may occur when one type of medical device is mistakenly attached to another type of medical device that performs a different function. Because these connectors are easy to use and may be compatible with different medical devices, users can mistakenly connect unrelated systems to one another.


This may cause medication or other substances to be delivered through the wrong tubing into the incorrect area of the body. These errors are sometimes called tubing misconnections, wrong route errors, catheter misconnections, or Luer misconnections and can result in patient injury or death.

How Reducing the Risk of Misconnection?

The way devices connect to each other are changing, greatly reducing the risk for misconnections. New design standards are being developed for tubing connectors for high-risk medical applications (e.g., enteral, respiratory, neuraxial), so that unrelated devices cannot connect with each other.


Hence, Medzus Medical is committed to the prevention of misconnections and actively supports the ongoing worldwide patient safety initiatives dedicated to reducing tubing misconnections by conforming ISO 80369 compliance devices.
