Abstract

Claims (17)

1. A medical device 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 comprising a sheet of flexible material which is adhered to the contact surface by a fold in the sheet of flexible material, wherein the sheet of flexible material covers the opening in the contact surface;

complementary means for mechanically coupling the parts at the contact surfaces to form the connector; and

wherein the sheet of flexible material is adhered to the contact surface with a temporary adhesive, and removed by pulling the fold away prior to mechanically coupling the first and the second parts, and characterized in that the openings of the first and second parts are not located in a rotational axis defined by a centre of counter-rotation of the first and second parts during coupling; and

a medical tubing set, comprising at least one freeze bag coupled to the connector and at least one tube, wherein the at least one 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, to accommodate at least one connector.

2. The medical device according to claim 1 wherein, the complementary means for mechanically coupling the parts are configured to mechanically interlock with each other by counter-rotation of the first and second parts; 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 the first and second parts.

3. The medical device according to claim 1 , wherein the sheet of flexible material includes the temporary adhesive on both the inner and the outer surfaces of the sheet of flexible material.

4. The medical device according to claim 1 , wherein the releasable coverings of the openings in the contact surfaces are attached to extricable grips, wherein the extricable grips are the grips of the releasable coverings of the first part and second part and are provided with complementary means for mechanically interlocking with each other.

5. The medical device according to claim 1 , wherein the sheet of flexible material has a thickness of at least 0.01 mm, and comprises a biocompatible polymer.

6. The medical device according to claim 1 , wherein the sheet of flexible material is removed by pulling the fold, such that the sheet of flexible material collapses together, encapsulating contamination between the surfaces of the sheet of flexible material.

7. The medical device according to claim 1 , wherein the temporary adhesive is at least one of a biocompatible silicone adhesive or a polyester adhesive.

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

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

10. The medical device according to claim 1 , characterized in that the openings in the non-contact surfaces of the first and the second parts are orthogonal to each other.

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