Abstract

The invention is directed to an connector comprising a first part and a second part, each provided with a contact surface and at least one non-contact surface facing away from the contact surface, at least one opening in the contact surface having an fluid connection to at least one opening of the non-contact surface, a releasable covering of the opening in the contact surface, and complementary means for mechanically coupling the parts at the contact surfaces to form the connector. The complementary means for mechanically coupling the parts are configured to mechanically interlock with each other.

First claim

What is claimed is:

1. A medical device with a connector comprising:
a first part and a second part, each provided with
a contact surface and at least one non-contact surface facing away from the contact surface,
at least one opening in the contact surface having a fluid connection to at least one opening of the non-contact surface,
a releasable covering of the opening in the contact surface, and
complementary means for mechanically coupling the parts at the contact surfaces to form the connector; and

a medical tubing set, comprising at least one freeze bag and at least one tube, wherein the at least one freeze bag is coupled to the connector and the at least one tube, wherein the freeze bag comprises at least one recess into which the connector is inserted, with the freeze bag and connector in fluid communication within the recess; and
characterized in that the complementary means for mechanically coupling the parts are configured to mechanically interlock with each other by counter-rotation of both the first and second parts about a single rotational axis which is orthogonal to the contact surfaces; and the openings in the contact surfaces are configured to be brought to match at least in part to provide fluid communication through the openings by counter-rotation of both the first and second parts about the rotational axis, wherein the openings in the contact surfaces of the first and second parts are not located in the rotational axis of the first and second parts which is defined by the centre of the counter-rotation of the first and second parts during coupling.

2. The connector according to claim 1 , characterized in that the releasable coverings of the openings in the contact surfaces are attached to extricable grips.

3. The connector according to claim 2 , characterized in that the extricable grips are provided with complementary means for mechanically interlocking with each other.

4. The connector according to claim 2 , characterized in that the first part and the second part are provided with grips which interlock before both grips and the release coverings can be removed together from the connector.

5. The connector according to claim 1 , characterized in that the releasable coverings are adhered as a folded double layer to the contact surfaces and configured to be peeled off the openings in the contact surfaces by simultaneously removing the mechanically interlocked grips at least in part from the mechanically interlocked first part and second part.

6. The connector according to claim 1 , characterized in that the releasable coverings are welded to the contact surfaces.

7. The connector according to claim 1 , characterized in that the first part and second part are provided with means that prevent the openings in the contact surfaces of the first part and second part to be brought to match at least in part to provide fluid communication through the openings before the releasable coverings are removed from the openings and the parts are rotated to the locked position.

8. The connector according to claim 1 , characterized in that the first and second parts are provided with means to optically indicate the relative positions of the first and second parts to each other during counter-rotation of the parts.

9. The connector according to claim 1 , characterized in that at least one of the openings of the first and second parts in the contact surfaces is provided with a gasket.

10. The connector according to claim 1 , characterized in that the openings in the non-contact surfaces are orthogonal to each other.

11. The connector according to claim 1 , characterized in that the openings in the non-contact surfaces are each provided with a Luer-lock adapter.
