Abstract

An infusion set adapted to be secured to a skin surface includes a fixed base member connectable to the skin surface and a movable member. A needle or cannula is connected to the movable member and movable relative to the fixed base member. The movable member is movable from a first position in which the needle or cannula is not exposed externally of the fixed base member to a second position in which the needle or cannula is exposed externally of the fixed base member. A release member retains the movable member in the first position. Removal of the release member allows movement of the movable slide member to the second position.

Claims

1. An infusion set adapted to be secured to a skin surface, comprising:

a fixed base member connectable to the skin surface;

a movable member having a needle or cannula connected thereto and movable relative to said fixed base member, said movable member being movable from a first position in which said needle or cannula is not exposed externally of said fixed base member to a second position in which said needle or cannula is exposed externally of said fixed base member; and

a release member retaining said movable member in said first position, removal of said release member allowing movement of said movable member to said second position.

2. The infusion set according to claim 1, wherein

said movable member moves in a direction not parallel to the skin surface.

3. The infusion set according to claim 1, wherein

a spring member is connected between said fixed base member and said movable member to move said movable member from said second position to said first position.

4. The infusion set according to claim 1, wherein

a needle of a connector pierces a septum upon connection to said infusion set.

5. The infusion set according to claim 4, wherein

said septum is disposed in said movable member.

6. The infusion set according to claim 4, wherein

said septum is disposed in said fixed base member.

7. The infusion set according to claim 6, wherein

flexible tubing is connected between said connector needle and said movable member.

8. The infusion set according to claim 1, wherein

said needle or cannula is disposed at a non-perpendicular angle relative to the skin surface when said movable member is in said second position.

9. The infusion set according to claim 1, wherein

said needle or cannula is disposed at an angle of approximately 20 degrees relative to the skin surface when said movable member is in said second position.

10. The infusion set according to claim 1, wherein

a length of said infusion set is reduced when said movable member moves from said first position to said second position.

11. The infusion set according to claim 3, wherein

said spring member substantially prevents movement of said movable member from said second position in a direction toward said first position.

12. The infusion set according to claim 1, wherein

movement of said movable member from said first position to said second position includes a first movement in a first direction and a second movement in a second direction, said first direction and said second direction being non-colinear.

13. The infusion set according to claim 12, wherein

said first direction is angularly toward the skin surface.

14. The infusion set according to claim 13, wherein

said second direction is substantially parallel to the skin surface.

15. The infusion set according to claim 4, wherein

said connector is connected from a front side of said movable member.

16. The infusion set according to claim 4, wherein

said connector is connected from a rear side of said movable member.

17. A method of inserting a cannula of an infusion set, comprising the steps of

placing an infusion set having a needle or cannula on an infusion site;

and

removing a release member from the infusion set to allow movement of a movable member of the infusion set from a first position to a second position in which the needle or cannula is inserted in the infusion site at a non-perpendicular angle.

18. The method according to claim 17, further comprising

connecting a connector to the infusion set after the needle or cannula is inserted in the infusion site.

19. The method according to claim 17, further comprising

connecting a connector to the infusion set before the needle or cannula is inserted in the infusion site.

20. The method according to claim 17, further comprising

moving said movable member from said first position to said second position comprises moving said movable member in a first direction angularly disposed relative to the infusion site and in a second direction substantially parallel to the infusion site.
