Performance and characteristics of luer connector of disposable infusion set

Luer connector (Luer taper) is a standardized micro-permeable connector, connected by a male Luer connector and a matching female Luer connector part. It is now widely used in medical and laboratory instruments.

A complete Luer connector should consist of a male Luer-Lok connection fitting and a female Luer-Lok fitting.

Luer connectors are convenient connection devices used in the medical industry that greatly simplify the management of liquid and gaseous medical fluids. The luer connector can switch 4 infusion bags without inserting or pulling out the patient's infusion needle. The connector also allows multiple compatible fluids to be administered through the same tubing, reducing trauma to the patient.

However, the ease of luer connection and compatibility between different products increases the risk of misconnection between incompatible systems and drug passing through the wrong line. This problem has been well known and documented in the medical field by a joint working group, which includes members of the US Food and Drug Administration (FDA), the International Electrotechnical Commission (IEC), the Association for the Advancement of Medical Instrumentation, and ISO, which brought together to create A unified set of standards for designing and testing Luer connections.
