Abstract

The present invention relates to a first medical device (1, 100) configured to permit connection to a second medical device (3). The medical device (1, 100, 200) comprises a guiding track (12) for receiving a lock protrusion (4). The guiding track (12) comprises a surface (16) having a lock edge (15) extending between a first and a second level (H1, H2). The lock edge (15) extends in a smooth curvature between the first and the second level (H1, H2), the curvature of which is a function of at least of radius (Ra). The medical device (1, 100) may comprise a neck element (11) with at least one guiding track (12) for receiving a lock protrusion (4) of a second medical device (3) or optionally the medical device may comprise a sleeve member (202) which comprises the guiding track (12). The present invention provide for a connection site which enables a smooth lock but especially a smooth unlock motion of the second medical device being connected.

Claims

1. A medical device comprising a first connection site for connecting a second medical device, said first connection site comprising;

at least one guiding track for guiding a lock protrusion on said second medical device,

said at least one guiding track being arranged with a surface comprising a locking edge, said locking edge being arranged to cooperate with said lock protrusion on said second medical device,

said locking edge extending between a first and a second level (H1, H2), wherein said locking edge having a smooth curvature between said first and said second level (H1, H2), the curvature of which is a function of at least one radius (Ra).

2. The medical device according to claim 1, wherein said radius (Ra) is between 1-10 mm.

3. The medical device according to claim 1 or 2, wherein said distance (b) between said first and said second level (H1, H2) is 0.2-3.0 mm.

4. The medical device according to claim 1, wherein said locking edge extends in a smooth curve between said first and said second level (H1, H2), and said curvature is a function of two radii.

5. The medical device according to claim 1, wherein said guiding track comprises at least a horizontal section said horizontal section, comprising a distal and proximal surface, and a first and a second vertical surface.

6. The medical device according to claim 5, wherein said radius (Ra) has a centre of origin (P_O) positioned at a distance (d) from said second vertical surface of said horizontal section of said guiding track.

7. The medical device according to claim 1, further comprising a neck element that extends from a base member for receiving a part of said second medical device into said neck element, said neck element comprising said at least one guiding track.

8. The medical device according to claim 7, wherein said neck element is a cylinder neck element.

9. The medical device according to 5, wherein said guiding track comprises a vertical section arranged substantially perpendicular to said horizontal section, said vertical section arranged to initially receive said lock protrusion during assembly.

10. The medical device according to claim 1, wherein said medical device is a piercing member protection device and said guiding track is arranged on said piercing member protection device.

11. The medical device according to claim 10, wherein said piercing member protection device comprises a sleeve member and said at least one guiding track is formed in said sleeve member.

12. The medical device according to claim 1, wherein said medical device comprises a second connection site for connecting an additional medical device.

13. The medical device according to claim 1, wherein said medical device comprises a barrier member, in that said barrier member arranged to cooperate with said lock protrusion of said second medical device so as to exert a force component to said second medical device.

14. The medical device according to claim 1, wherein said medical device is a piercing member free medical device.

15. The medical device according to claim 1, wherein said distance (b) between said first and said second level (H1, H2) is 0.2-1.0 mm.
