Connector for medical lines

摘要

A connector for medical infusion lines, transfusion lines, and the like, includes a tubular body having at one end a male connector including an inner tubular element and an outer hollow element, which is internally threaded and can be coupled by screwing to a complementary female connector. The line connector further includes an outer maneuvering sleeve coupled in unidirectional rotation to the body in the direction corresponding to screwing of the male connector with respect to the complementary female connector and free to turn in the opposite direction, formed by two parts coupled together on the body of the connector.

1. A connector for medical infusion lines and transfusion lines, comprising:
a tubular body having at one end a male connector including an inner tubular element and an outer hollow element, which is internally threaded and can be coupled by screwing to a complementary female connector; an outer maneuvering sleeve coupled in unidirectional rotation to the body of the connector in a first direction corresponding to screwing of said male connector with respect to said complementary female connector; and said outer maneuvering sleeve being free to turn in a second opposite direction relative to the first direction and formed by two parts coupled together on said body of the connector; said outer sleeve comprising two radial half-shells; said tubular body and said outer sleeve mutually displaceable axially between a first position and a second position, said tubular body and said outer sleeve coupled together in said first position in unidirectional rotation in said first direction of screwing of said male connector; said sleeve comprising elastically sprung appendages, said appendages tending to keep said outer sleeve and said body normally in said first position; and said body and said sleeve comprising coupling members coupling in rotation said sleeve and said tubular body in the second opposite direction corresponding to unscrewing of said male connector.
