Medical coupling and medical system comprising medical coupling
A coupling for fluid-tight connection of two fluid-guiding portions in medical applications. The coupling is an axially lockable quick-connect coupling and comprises a male coupling portion having a continuous first passage and a female coupling portion adapted to be slipped over the male coupling portion and having a continuous second passage. A preferably circumferential radial sealing is provided on the outer periphery of the male coupling portion and/or on the inner periphery of the female coupling portion.
1. A medical coupling for fluid-tight connection of two fluid-guiding portions in medical applications, the medical coupling defining a longitudinal axis and comprising:
a male coupling portion having a continuous first passage and an outer periphery; and
a female coupling portion adapted to be slipped over the male coupling portion and having a continuous second passage and an inner periphery;
wherein a circumferential radial sealing is provided on at least one of the outer periphery of the male coupling portion or the inner periphery of the female coupling portion;
wherein the male coupling portion includes a shoulder or a stop, which delimits movement of the female coupling portion in an axial direction and provides for a pre-defined shifting distance of the female coupling portion on the male portion;
wherein the medical coupling is an axially lockable quick-connect coupling; and
wherein the male coupling portion and the female coupling portion are connected to each other by a locking device comprising a pin having a long dimension extending radially inwardly toward the longitudinal axis of the medical coupling and a groove, the pin comprising a first end articulated to an end of a lever and a second end configured to fit into the groove.
2. The medical coupling according to claim 1 , wherein:
the male coupling portion is formed integrally with a medical apparatus.
3. The medical coupling according to claim 1 , wherein:
the male coupling portion includes a first fastening portion; and
the male coupling portion is adapted to be fastened to a medical apparatus via the first fastening portion.
4. The medical coupling according to claim 3 , wherein:
the first fastening portion of the male coupling portion is a first Luer lock that is connectable to a second Luer lock of the medical apparatus.
5. The medical coupling according to claim 4 , wherein the first Luer lock comprises a female internal cone and the second Luer lock comprises a male external cone.
6. The medical coupling according to claim 5 , wherein:
the female coupling portion includes a second fastening portion adapted to be fastened to a fluid line;
the second fastening portion of the female coupling portion is a third Luer lock that is connectable to a fourth Luer lock of the fluid line; and
the third Luer lock comprises a male external cone and the fourth Luer lock comprises a female internal cone.
7. The medical coupling according to claim 1 , wherein:
the female coupling portion is formed integrally with a fluid line.
8. The medical coupling according to claim 1 , wherein:
the female coupling portion includes a fastening portion; and
the female coupling portion is adapted to be fastened to a fluid line via the fastening portion.
9. The medical coupling according to claim 8 , wherein:
the fastening portion of the female coupling portion is a first Luer lock that is connectable to a second Luer lock of the fluid line.
10. The medical coupling according to claim 9 , wherein:
the first Luer lock comprises a male external cone and the second Luer lock comprises a female internal cone.
11. The medical coupling according to claim 1 , wherein:
the male coupling portion includes a circumferential groove configured to engage a part of the female coupling portion.
