Abstract

The invention faces the technical problem of reducing the manufacturing costs of medical devices while at the same time a secure, quick and easy reception of a needle by said medical device is guaranteed. The technical problem is solved by a needle guide configured to receive a needle in a first opening in an axial direction of the needle guide, comprising a guide area comprising the first opening and a second opening, a flange area and a connection area, wherein said connection area is configured to non-detachably connect said needle guide to a medical device and wherein said needle guide is made of metal. The technical problem is further solved by a method to produce a needle guide, wherein said needle guide comprises a guide area, a flange area and a connection area, comprising the steps of deep drawing a metal sheet to produce the guide area.

Claims

1-13. -13. (canceled)

14. A needle guide configured to receive a needle in a first opening in an axial direction of the needle guide, comprising

a guide area comprising the first opening and a second opening,

a flange area and

a connection area,

wherein said connection area is configured to non-detachably connect said needle guide to a medical device and

wherein said needle guide is made of metal.

15. A needle guide according to claim 14, wherein at least said guide area is produced by deep drawing a metal sheet.

16. A needle guide according to claim 14, wherein said guide area is substantially cylindrical in the axial direction and tapers at least in parts from the first opening of guide area to the second opening of the guide area.

17. A needle guide according to claim 14, wherein the flange area is adjacent to the guide area, said flange area is substantially circular and said flange area is extending substantially perpendicular to the axial direction.

18. A needle guide according to claim 14, wherein said connection area extends substantially into the axial direction or perpendicular to the axial direction.

19. A needle guide according to claim 14, wherein said connection area comprises a plurality of projections separated by recesses and substantially projecting in the axial direction.

20. A needle guide according to claim 19, wherein said projections are angled compared to the axial direction.

21. A needle guide according to claim 19, wherein said projections are angled compared to the axial direction alternating towards the guide area and away from the guide area.

22. An apparatus comprising a needle guide according to claim 14, wherein said apparatus is a medical device configured to eject at least one medicament, or a dispense interface attachable to a medical device configured to eject at least one medicament.

23. A method to produce a needle guide according to claim 14, wherein said needle guide comprises a guide area, a flange area and a connection area, comprising the steps of deep drawing a metal sheet to produce the guide area.

24. A method according to claim 23, wherein said guide area, said flange area and said connection area are produced at least in part by said step of deep drawing said metal sheet.

25. A method according to claim 23, further comprising the step of pressing said needle guide into a medical device.

26. A method according to claim 25, wherein said medical device is a dispense interface, in particular a needle hub.
