Connector, connector system, and use thereof

1. A connector ( 10 ) for sterile connection to a complementary connector ( 12 ), wherein the connector ( 10 ) comprises

a connector housing ( 14 ) with a sensor chamber ( 38 ) and with:

an engagement device ( 16 ), which is designed such that

it enters into engagement with a complementary engagement device ( 18 ) of the complementary connector ( 12 ) essentially along an engagement direction ( 44 ), and

that, after the engagement device ( 16 ) enters into engagement with the complementary engagement device ( 18 ), the connector ( 10 ) is configured to be displaced the complementary connector ( 12 ) essentially along the engagement direction ( 44 );

a feed-through opening ( 24 ), for feeding a sensor device ( 34 ) through;

a displaceable, sterile covering device ( 22 ), which is configured

to close the feed-through opening ( 24 ) in an essentially sterile manner, and

that, when the connector ( 10 ) is displaced relative to the complementary connector ( 12 ), the covering device ( 22 ) is displaced relative to the connector ( 10 ) essentially along the engagement direction ( 44 ),

and with an essentially sterile sensor device ( 34 ) disposed at least partly within the sensor chamber ( 38 ), wherein

the sensor device ( 34 ) is movable relative to the connector housing ( 14 ) essentially along a sensor displacement direction ( 52 ), and wherein

the engagement direction ( 44 ) differs from the sensor displacement direction ( 52 ), and whereby

the sensor chamber ( 38 ) is formed at least partly of a flexible material configured to reset and is prestressed along the sensor displacement direction ( 52 ), so that a force is transmitted to the sensor ( 34 ) and the sensor ( 34 ) is moved automatically along the sensor displacement direction and toward the complementary connector ( 12 ) as soon as the connector ( 10 ) and the complementary connector ( 12 ) are in a use position.

2. The connector ( 10 ) of claim 1 , wherein the sensor chamber ( 38 ) has an essentially sterile interior, and the sensor chamber ( 38 ) contains the feed-through opening ( 24 ).

3. The connector ( 10 ) claim 2 , wherein the connector housing ( 14 ) is at least partially composed of a flexible material, and the connector housing ( 14 ) is designed in such a manner that the volume of the sensor chamber ( 38 ) can be varied.

4. The connector ( 10 ) of claim 3 , wherein at least part of the connector housing ( 14 ) is compressible or extendible.

5. The connector ( 10 ) of claim 3 , wherein at least part of the connector housing ( 14 ) is compressible and extendible.

6. The connector ( 10 ) of claim 2 , wherein the connector ( 10 ) is designed, after arrangement of the connector ( 10 ) with the complementary connector ( 12 ), to connect the sensor chamber ( 38 ) to an interior space of the complementary connector in an essentially sterile manner.

7. The connector ( 10 ) of claim 1 , wherein the connector housing ( 14 ) is at least partially composed of a material capable of being reset.

8. The connector ( 10 ) of claim 1 , wherein the connector housing ( 14 ) is designed to exert a force on the sensor device ( 34 ).

9. The connector ( 10 ) of claim 8 , wherein the connector housing ( 14 ) is designed, after connection of the connector ( 10 ) to the complementary connector ( 12 ), to move the sensor device ( 34 ) at least partially into the complementary connector ( 12 ).

10. The connector ( 10 ) of claim 1 , wherein, after removal of the covering device ( 22 ) and of the complementary covering device ( 30 ), the sensor device ( 34 ) is movable through the feed-through opening ( 24 ) into the interior space of the complementary connector ( 12 ).

11. The connector ( 10 ) of claim 1 , which is designed such that a fluid can flow through it.

12. The connector ( 10 ) of claim 1 , wherein the connector ( 10 ) has a further opening ( 54 ) for the passage of fluid.

13. A connector ( 10 ) for sterile connection to a complementary connector ( 12 ), the complementary connector ( 12 ) including an inlet ( 50 ) and a complementary engagement device ( 18 ), the connector ( 10 ) comprising:

a connector housing ( 14 ) formed at least partly from a rigid material and including an engagement device ( 16 ) configured to enter into engagement with the complementary engagement device ( 18 ) of the complementary connector ( 12 ) along an engagement direction ( 14 ), the connector housing ( 14 ) having a feed-through opening ( 24 ) aligned along a displacement direction ( 52 ) substantially normal to the engagement direction ( 44 ) when the connector ( 10 ) is connected to the complementary connector ( 12 ), a sterile covering device displaceably mounted on the connector housing ( 14 ) and movable along the engagement direction ( 44 ) between a closed position where the sterile covering device ( 22 ) closes the feed-through opening ( 24 ) in an essentially sterile manner and a displaced position where the covering device ( 22 ) is displaced at least partly from the feed-through opening ( 24 );

a sensor chamber ( 38 ) mounted to the connector housing ( 14 ) and formed at least partly of a flexible material capable of being reset, the flexible material of the sensor chamber ( 38 ) being prestressed along the displacement direction ( 52 ); and

a sensor device ( 34 ) mounted in the sensor chamber ( 38 ) and communicating with the feed-through opening ( 24 ) of the connector housing ( 14 ) so that the flexible prestressed material of the sensor chamber ( 38 ) exerts a force on the sensor ( 34 ) along the displacement direction ( 52 ) so that the sensor ( 34 ) is moved automatically along the displacement direction ( 52 ) and toward the complementary connector ( 12 ) as soon as the connector housing ( 14 ) is moved sufficiently in the engagement direction ( 44 ) for the feed-through opening ( 24 ) to align with the inlet ( 50 ) of the complementary connector ( 12 ).
