Male luer lock connector
Connector for medical use comprising: a body joined to a line or adapted to be connected at one of its ends to a tubing in which a fluid flows, and a male luer lock connection comprising a base mounted rotatingly on the body and cooperating by friction with it, without any possible translational movement. The base is joined to a hollow tubular body, having a threaded inner surface and a male central luer cone. The outer surface of the body and the inner surface of the base of the connection, cooperating by friction, have a spherical then cylindrical shape.
1. A connector for medical use comprising:
a body joined to a line or adapted to be connected at one end to a tubing in which a fluid flows,
a male luer lock connection comprising a base mounted rotatingly on the body and cooperating by friction with the body, without any possible translational movement, the base being joined to a hollow tubular body, having a threaded inner surface and a central male luer cone,
wherein the connector has no additional element that acts as a seal between the body and the base, and an outer surface of the body and an inner surface of the base cooperate by friction, the outer surface of the body having at least two successive lengths, respectively:
a first length in the form of a portion of sphere having diameter d 1 , and
a second cylindrical length having diameter d 2 smaller than d 1 ; and
the inner surface of the base having:
a first zone in the form of a portion of sphere having a diameter d 7 substantially equal to d 1 , and
a second tubular zone, having a diameter d 3 slightly smaller than d 2 ; and
wherein the outer surface of the body further includes an additional cylindrical length having diameter d 4 , the additional cylindrical length preceding the first length, the diameter d 4 being substantially equal to the diameter d 1 of the largest cross section of the portion of sphere.
2. The connector according to claim 1 , wherein the first zone is preceded by a tubular zone having diameter d 6 smaller than d 1 .
3. The connector according to claim 1 , wherein the first length is preceded by a linkage zone having a diameter d 5 and an outer surface of any shape.
4. A valve equipped with the connector of claim 1 .
5. A ramp equipped with the connector of claim 1 .
6. A Y-piece connector equipped with the connector of claim 1 .
7. A perfusion tube equipped with the connector of claim 1 .
8. An extension equipped with the connector of claim 1 .
