Abstract

The present invention concerns a female piercing member protection device for connection with a male connection part, as well as a method for connecting such protection device to a male connection part. The female piercing member protection device comprises; an outer casing, a connection member wherein the connection member is arranged to, and at least partly enclosed in, the outer casing. Further is the outer casing arranged to be moved between a first and a second position, wherein when the outer casing is in its first position, the connection member is substantially locked from movement along the longitudinal axis A, and when the outer casing is in its second position the connection member is able to move along the longitudinal axis A. The female piercing member protection device also comprises an activated position and an inactivated position. The connection member is further arranged to connect to the male connection part by means of a deformable locking device, wherein when the outer casing is in the second position, the deformable locking device is prevented from deformation by the outer casing so as to prevent disengagement of the male connection part. The present invention provides for a secure piercing member protection device which significantly minimizes the risk for a user to be exposed to contaminants and the piercing member itself.

Claims

1. A female piercing member protection device, having a longitudinal axis (A), for connection with a male connection part, said female piercing member protection device comprising:

an outer casing having a first and a second end and an inner and an outer side, a connection member having a first and a second end, said connection member arranged to and at least partly enclosed in said outer casing, further said outer casing arranged to be moved between a first and a second position, wherein when said outer casing is in its first position, the connection member is substantially locked from movement along the longitudinal axis A, and when said outer casing is in its second position the connection member is able to move along the longitudinal axis A, and wherein said female piercing member protection device comprises an activated position and an inactivated position, characterized in that said connection member is arranged to connect to said male connection part by means of a deformable locking device, wherein when said outer casing is in said second position, said deformable locking device is prevented from deformation by said outer casing so as to prevent disengagement of said male connection part.

2. The female piercing member protection device according to claim 1, characterized in that said connection member is arranged between said first and second end of said outer casing.

3. The female piercing member protection device according to claim 2, characterized in that said deformable locking device comprises at least one deformable locking flange.

4. The female piercing member protection device according to claim 3, characterized in that said deformable locking flange is an integrated part of the connection member.

5. The female piercing member protection device according to claim 3 or 4, characterized in that said outer casing comprises at least one aperture and when said connection member is in said first position, said aperture and said deformable locking flange is substantially aligned, so that said deformable locking flange can deform into said aperture during connection with said male connection part.

6. The female piercing member protection device according to claim 5, characterized in that when said outer casing is in said second position, said deformable locking flange is displaced from said aperture in said outer casing, so that said deformable locking flange is substantially unable to disengage from said male connection part.

7. The female piercing member protection device according to any of claim 5, characterized in that said connection member comprises at least two opposing deformable flanges.

8. The female piercing member protection device according to claim 7, characterized in that said connection member comprises at least four opposing deformable flanges.

9. The female piercing member protection device according to claim 3 or 4, characterized in that said inner side of said outer casing comprises a cavity, and when said connection member is in said first position, said cavity and said deformable lock flange is substantially aligned, so that said deformable locking flange can deform into said cavity during connection with said male connector.

10. The female piercing member protection device according to claims 1, 2, 3 or 4, characterized in that said female piercing member protection device comprises a second locking device which can substantially lock said connection member from movement along said longitudinal axis (A), when said connection member is in said activated position.

11. The female piercing member protection device according to claim 10, characterized in that said second locking device comprises a locked position in which said connection member is substantially unable to slide along said longitudinal axis (A), and an unlocked position in which said connection member is substantially able to slide along said longitudinal axis (A).

12. The female piercing member protection device according to claim 11, characterized in that said second locking device comprises a manually locking device or an automatic locking device.

13. The female piercing member protection device according to claims 1, 2, 3 or 4, characterized in that said connection member comprises at least one barrier member.

14. The female piercing member protection device according to claim 13, characterized in that said connection member comprises two barrier members.

15. The female piercing member protection device according to claim 14, characterized in that two barrier members are arranged substantially parallel with respect each other and so as to intersect the longitudinal axis (A).

16. The female piercing member protection device according to claim 15, characterized in that said two barrier members are arranged so as to form a piercing tip protection chamber therebetween.

17. A method for connecting a female piercing member protection device according to claims 1, 2, 3 or 4, with a male connection part, said method comprising the steps of:

connecting said connection member to said male connection by means of said deformable locking device, moving said outer casing with respect to said connection member from a first position, in which said female piercing member protection device is in an inactivated state and in which said connection member is substantially unable to slide along said longitudinal axis (A), to a second position, in which said female piercing member protection device is in an inactivated state and in which said connection member is substantially able to slide along said longitudinal axis (A), wherein when said outer casing is in said second position, said male connection part is substantially unable to disengage from said piercing member protection device.

18. The method for connecting a female piercing member protection device with a male connection part according to claim 17, characterized in that said female piercing member protection device is thereafter activated by moving said connection member to said activated position.

19. The method for connecting a female piercing member protection device with a male connection part according to claim 18, characterized in that said connection member can be substantially locked in said activated position by means of a locking ring arranged around the outer casing.

20. The method for connecting a female piercing member protection device with a male connection part according to claim 17, characterized in that said deformable flange provides a snap-on connection.

21. A male connection part for connection with a female piercing member protection device comprising a longitudinal cylinder like body having a longitudinal axis C, a first and a second side, an outer and an inner surface, a barrier member arranged at the centre of the first side of the male connection member, intersecting the longitudinal axis C, and a fluid communication channel extends from the barrier member of the male connection part to the second side of the male connection part, characterized in that said male connection part comprises at least one turning grip protrusion to provide for an increased turning friction between the female piercing member protection device after assembly.
