Abstract

The invention relates to a medical puncturing device comprising a rigid needle being at one end adapted for facilitating the puncturing and comprising at the opposite end a hub, the hub comprising a handle part and a shield part being pivotable in relation to the handle part and further comprising locking means on the shield part and the handle part, the locking means being adapted to interlock the shield and the handle part in a pivoted position of the shield part where the rigid needle is covered by this.

Claims

1. A medical puncturing device comprising a rigid needle being at one end adapted for facilitating the puncturing and comprising at the opposite end a hub, the hub comprising a handle part and a shield part being pivotable in relation to the handle part, and further comprising locking means on the shield part and the handle part, the locking means being adapted to interlock the shield and the handle part in a pivoted position of the shield part where the rigid needle is covered by this.

2. A medical puncturing device as claimed in claim 1, wherein the shield part comprises a recess for accommodating the rigid needle.

3. A medical puncturing device as claimed in claim 1, wherein the shield part has an essentially U-shaped cross section.

4. A medical puncturing device as claimed in claim 1, wherein the locking means on the handle part comprises two arms having on their opposed sides barbs adapted to interlock with the corresponding locking means of the shield part.

5. A medical puncturing device as claimed in claim 4, wherein the edges of the barbs are tapered so as to facilitate the insertion into the corresponding locking means of the shield part.

6. A medical puncturing device as claimed in claim 1, wherein the locking means on the shield part comprises two side flanges adapted to interlock with the corresponding locking means of the handle part.

7. A medical puncturing device as claimed in claim 6, wherein the edges of the flanges are tapered so as to facilitate the insertion into the corresponding locking means of the handle part.

8. A medical puncturing device as claimed in claim 1, wherein the shield part comprises an operating handle.

9. A medical puncturing device as claimed in claim 1, wherein the hub is formed as a single part and where the transition area between the handle part and the shield part is an area with a reduced rigidity.

10. A medical puncturing device as claimed in claim 1, wherein the hub is made of a plastics material.
