Device for receiving an injection syringe comprising a protective cap for the needle

1. A receiving device for an injection syringe, configured to receive an injection syringe comprising a needle and a protective cap for the needle, the receiving device having a distal end and being characterized in that it comprises a removal member serving to remove the protective cap and being removably fastened to the distal end of the receiving device, the removal member comprising a gripping section for gripping by a user, and a catch for catching on the cap, which are able to entrain the cap when the removal member is withdrawn from the receiving device, in such a way as to expose the needle, wherein the catch comprises deformable tabs each having a retaining lug;

the receiving device further comprising a part in the form of a ring extending around outside surfaces of the deformable tabs, wherein the part can cooperate with the deformable tabs to secure the protective cap in the removal member by deforming the deformable tabs inward against the protective cap and the part is withdrawn from the receiving device when the removal member is withdrawn from the receiving device;

wherein the part is distinct from the gripping section;

wherein, when the removal member is fastened to the distal end of the receiving device, the part and the deformable tabs are movable with respect to one another from a first position, to a second position in which the part is maintained against the outside surfaces of the deformable tabs and deforms the deformable tabs inward against the protective cap.

2. The receiving device as claimed in claim 1 , in which the receiving device is a safety device having a protective sheath for the needle.

3. The receiving device as claimed in claim 1 , in which the receiving device comprises, at its distal end, an attached member called an end member, the removal member being fastened removably to this end member.

4. An assembly comprising a receiving device as claimed in claim 3 , wherein the end member covers a part of a length of the needle protruding beyond an end piece of the injection syringe, the end member being thus able to bear on the injection site in order to limit a depth of insertion of the needle.

5. The receiving device as claimed in claim 1 , in which the gripping section comprises an anti-slip element.

6. The receiving device as claimed in claim 5 , wherein the anti-slip element includes raised elements carried by an outer surface of the removal member.

7. An assembly comprising a receiving device as claimed in claim 1 and the injection syringe comprising the needle and the protective cap for the needle.

8. A method for assembly of a receiving device as claimed in claim 1 and of an injection syringe comprising the needle and the protective cap for the needle, the method being characterized in that it comprises the following steps:

the removal member is firstly fastened to the distal end of the receiving device, and

the injection syringe provided with the protective cap is inserted into the receiving device, via a proximal end of the receiving device, such that the protective cap becomes rigidly connected to the removal member.

9. A receiving device for an injection syringe, configured to receive an injection syringe comprising a needle and a protective cap for the needle, comprising:

a sheath for receiving the injection syringe, the sheath having a distal end;

a removal member serving to remove the protective cap and being removably fastened to the distal end of the sheath, the removal member comprising a gripping section for gripping by a user, and a catch for catching on the cap, which is able to entrain the cap when the removal member is withdrawn from the receiving device, in such a way as to expose the needle;

wherein the catch comprises deformable tabs each having a retaining lug;

wherein the removal member comprises a ring positioned adjacent to outside surfaces of the deformable tabs for securing the protective cap in the removal member, in such a way as to rigidly connect the cap and the removal member to each other when the removal member is withdrawn from the receiving device, the ring being distinct from the gripping section and the catch;

wherein, when the removal member is fastened to the distal end of the sheath, the ring and deformable tabs are movable with respect to one another from a first position, to a second position in which the ring is maintained against the outside surfaces of the deformable tabs and deforms the deformable tabs inward against the protective cap.

10. The receiving device as claimed in claim 9 , wherein the distal end sheath comprises an end member attached thereto, the removal member being removably fastened to the end member.

11. An assembly comprising a receiving device as claimed in claim 10 , wherein the end member covers a part of a length of the needle protruding beyond an end piece of the injection syringe, the end member being thus able to bear on the injection site in order to limit the depth of insertion of a needle.

12. The receiving device as claimed in claim 9 , in which the gripping section comprises an anti-slip element.

13. The receiving device as claimed in claim 12 , wherein the anti-slip element includes raised elements carried by an outer surface of the removal member.

14. An assembly comprising a receiving device as claimed in claim 9 and the injection syringe comprising the needle and the protective cap for the needle.

15. A method for assembly of a receiving device as claimed in claim 9 and of the injection syringe comprising the needle and the protective cap for the needle, the method being characterized in that it comprises the following steps:

the removal member is firstly fastened to the distal end of the sheath, and

the injection syringe provided with the protective cap is inserted into the sheath, via a proximal end of the sheath, such that the protective cap becomes rigidly connected to the removal member.
