Abstract

A connector assembly has a connector ( 10 ) with a fluid leadthrough ( 20 ) and a contact device ( 14 ). The contact device has an essentially planar contact surface ( 16 ) and a fluid leadthrough opening ( 18 ) passing through the contact surface ( 16 ). A sterile covering ( 64 ) sterilely covers at least part of the contact surface ( 16 ) and/or an end of the fluid leadthrough opening ( 20 ) adjacent the contact surface ( 16 ). A coupling device ( 22 ) is provided in proximity to the contact surface ( 16 ) outwardly from the fluid leadthrough opening ( 18 ). The connector assembly further includes a complementary connector ( 12 ) with a complementary coupling device ( 34 ) that can engage with the coupling device ( 22 ) along a coupling direction ( 40 ) that is essentially parallel to the contact surface ( 16 ).

First claim

The invention claimed is:

1. A connector system comprising:
a connector ( 10 ) having an essentially planar contact surface ( 16 ) and a fluid leadthrough opening passing through the contact surface ( 16 ), a peripheral wall extending partly around the planar contact surface ( 16 ) and disposed outwardly from the fluid leadthrough opening ( 18 ), the peripheral wall having opposite ends spaced from one another and defining a coupling opening ( 52 ) therebetween, the peripheral wall having an outside diameter, a shoulder ( 68 ) extending radially in from the peripheral wall and facing the planar contact surface ( 16 ), two openings ( 44 ) passing through the peripheral wall at positions opposite the coupling opening ( 52 ) and between the shoulder ( 68 ) and the planar contact surface ( 16 ), the connector ( 10 ) further having a rear surface ( 17 ) facing substantially oppositely from the contact surface ( 16 );
a sterile covering ( 64 ) sterilely and removably covering at least a part of the contact surface ( 16 ) and the fluid leadthrough opening ( 20 ), part of the sterile covering ( 64 ) projecting out beyond the contact surface ( 16 ) at a position opposite the opening ( 44 );
a complementary connector ( 12 ) having an end and a complementary shoulder ( 58 ) adjacent the end, the complementary shoulder ( 58 ) being slidably insertable along a coupling direction ( 40 ) parallel to the contact surface ( 16 ) into a space inward of the peripheral wall of the connector ( 10 ) and between the contact surface ( 16 ) and the shoulder ( 68 ), two arms ( 50 ) projecting from the complementary shoulder ( 58 ) parallel to the planar contact surface ( 16 ) and having hooks ( 42 ) projecting from leading end portions of the arms ( 50 ), the arms ( 50 ) being deflectable substantially parallel to the contact surface ( 16 ) and substantially perpendicular to the coupling direction ( 40 ), the hooks ( 42 ) engaging a part of the peripheral wall of the connector ( 10 ) adjacent the openings ( 44 ) of the peripheral wall for preventing movement of the complementary connector ( 12 ) in a direction against the coupling direction ( 40 ), an external thread ( 36 ) formed on a part of the complementary connector ( 12 ) spaced from the end of the complementary connector ( 12 ) and from the complementary shoulder ( 58 ) and disposed so that the shoulder ( 68 ) is between the complementary shoulder ( 58 ) and the part of the complementary connector ( 12 ) having the external thread ( 36 ) when the connector ( 10 ) and the complementary connector ( 12 ) are connected, the part of the complementary connector ( 12 ) with the external thread ( 36 ) having an outside diameter greater than the outside diameter of the peripheral wall of the connector ( 10 ); and
a lock nut ( 24 ) having a flange ( 53 ) engaging the rear surface ( 17 ) of the connector ( 10 ) and an internally threaded sidewall ( 54 ) projecting from the flange ( 53 ), the internally threaded sidewall ( 54 ) threadedly engaging the external thread ( 36 ) of the complementary connector ( 12 ) while surrounding the peripheral wall and the shoulder ( 68 ) of the connector ( 10 ) and the complementary shoulder ( 58 ) of the complementary connector ( 12 ) for preventing movement between the complementary shoulder ( 58 ) and the contact surface ( 16 ).

2. The connector system as claimed in claim 1 , in conjunction with which the connector ( 10 ) has a tube ( 20 ) defining the fluid leadthrough ( 16 ), the tube ( 20 ) extending from the rear surface ( 17 ) of the connector ( 10 ).

3. The connector system as claimed in claim 2 wherein the flange ( 53 ) of the lock nut ( 24 ) has a central opening that surrounds the tube ( 20 ) extending from the rear surface ( 17 ), the fluid leadthrough opening ( 18 ) extending through the tube ( 20 ).

4. The connector system as claimed in claim 1 , wherein the hooks ( 42 ) project from surfaces of the arms ( 50 ) facing one another, each hook ( 42 ) having a projection surface ( 46 ) aligned substantially normal to the coupling direction ( 40 ), the peripheral wall of the connector ( 10 ) having locking shoulders ( 48 ) adjacent the openings ( 44 ) and aligned substantially normal to the coupling direction ( 40 ), the projection surfaces ( 46 ) of the hooks ( 42 ) being lockable to the locking shoulders ( 48 ) of the peripheral wall.

5. The connector system as claimed in claim 4 , wherein the peripheral wall of the connector ( 10 ) has an outer circumferential surface, the locking shoulders ( 48 ) being inward of the outer circumferential surface.

6. The connector system as claimed in claim 1 , wherein the sterile covering ( 64 ) is disposed sufficiently inward of the peripheral wall to avoid interference with the arms ( 50 ) when the complementary shoulder ( 58 ) is slidably inserted along the coupling direction ( 40 ) into a space inward of the peripheral wall of the connector ( 10 ) and between the contact surface ( 16 ) and the shoulder ( 68 ).
