SAFE LUER CONNECTOR Russian patent published in 2013 - IPC A61M39/10 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medical equipment. A connector comprises an enclosed connector having a body with a remote end and a near end and a projection from the body having an external conical surface with a Luer cone, and a hole formed on the remote end of the projection and being in a liquid connection with a liquid passage in the body of the enclosed connector. The projection has the length L1. An enclosing connector has a body with a remote and a near end and an internal liquid passage having an internal conical surface with a Luer cone used for tight coupling with the internal conical surface of the enclosed connector, and an element projecting into the internal liquid passage from the internal conical surface. The element is placed at the distance of the length L2 from the near end of the enclosing connector and prevents the projection from being inserted into the element at L1=L2 so that the external conical surface of the enclosed Luer connector with the projection having the length exceeding the length L1 cannot be tightly coupled with the internal conical surface of the enclosing connector. There are disclosed versions of the connector differing by the structural implementation.

EFFECT: providing the reliable fixation of the elements and eliminating a risk of improper connection of the connector components.
