Abstract

An insertion device, generally used with an infusion set, including a needle being adapted for puncturing at one end and including at the opposite end a hub. The hub includes a handle part and a guard part that are capable of securing the needle through the use of locks. Locking structures are used to secure the insertion device in a position where the needle is covered in a locked position, avoiding unintended contact with the needle.

Claims

1. An insertion set, comprising:

a cannula housing of an infusion set including a cannula adapted to be inserted into the skin of a patient; and

an insertion device including;

a hub removably attachable to a base of the cannula housing of the infusion set, including a handle part and a guard part;

a needle attached to the hub, wherein the guard part is adapted to cover the needle; and

a collapse part attached to the handle part and having two opposing collapsible walls that are biased to improve collapse of both walls when pressure is applied to the collapse part.

2. The insertion set of claim 1, wherein the handle part is disposed between the collapse part and the guard part.

3. The insertion set of claim 1, further including a push block connected to the collapse part.

4. The insertion set of claim 3, wherein the collapse part is configured to flex inwards towards the needle and into the push block, and wherein the push block is configured to move the needle into a needle recess of the guard part.

5. The insertion set of claim 1, wherein the insertion device further includes locks adapted to secure the needle in the guard part when the needle is covered by the guard part.

6. The insertion set of claim 5, wherein the locks are catches positioned inside the hub on opposite sides that lock when pushed together.

7. The insertion set of claim 6, wherein the catches lock together when said collapsible walls are collapsed.

8. The insertion set of claim 6, wherein the catches lock the needle within the guard part.

9. The insertion set of claim 1, wherein the needle is configured to extend through the cannula of the cannula housing and beyond an outer tip thereof when the insertion device is attached to the cannula housing.

10. The insertion set of claim 1, wherein the guard part includes a needle recess to house the needle.

11. The insertion set of claim 1, wherein the collapse part is composed of material that flexes without fracturing.

12. An insertion device, comprising:

a hub removably attachable to a base of a cannula housing of an infusion set, including a handle part and a guard part;

a needle attached to the hub, wherein the guard part is adapted to cover the needle; and

a collapse part attached to the handle part and having two opposing collapsible walls that are biased to improve collapse of both walls when pressure is applied to the collapse part.

13. The insertion device of claim 12, wherein the handle part is disposed between the collapse part and the guard part.

14. The insertion device of claim 12, further including a push block connected to the collapse part.

15. The insertion device of claim 14, wherein the collapse part is configured to flex inwards towards the needle and into the push block, and wherein the push block is configured to move the needle into a needle recess of the guard part.

16. The insertion device of claim 12, further including locks adapted to secure the needle in the guard part when the needle is covered by the guard part.

17. The insertion device of claim 16, wherein the locks are catches positioned inside the hub on opposite sides that lock when pushed together.

18. The insertion device of claim 17, wherein the catches lock together when said collapsible walls are collapsed.

19. The insertion device of claim 17, wherein the catches lock the needle within the guard part.

20. The insertion device of claim 12, wherein the needle is configured to extend through a cannula of the cannula housing and beyond an outer tip thereof when the insertion device is attached to the cannula housing.

21. The insertion device of claim 12, wherein the guard part includes a needle recess to house the needle.

22. The insertion device of claim 12, wherein the collapse part is composed of material that flexes without fracturing.

23. A method for covering an insertion needle, comprising:

inserting a cannula into the skin of a patient with an insertion device, wherein the insertion device includes;

a hub removably attachable to a base of a cannula housing of an infusion set, including a handle part and a guard part;

a needle attached to the hub, wherein the guard part is adapted to cover the needle; and

a collapse part attached to the handle part and having two opposing collapsible walls that are biased to improve collapse of both walls when pressure is applied to the collapse part;

removing the insertion device from the cannula housing; and

covering the needle of the insertion device with the guard part.

24. The method of claim 23, wherein the handle part is disposed between the collapse part and the guard part.

25. The method of claim 23, wherein the insertion device further includes a push block connected to the collapse part.

26. The method of claim 25, wherein the collapse part is configured to flex inwards towards the needle and into the push block, and wherein the push block is configured to move the needle into a needle recess of the guard part.

27. The method of claim 23, wherein the insertion device further includes locks adapted to secure the needle in the guard part when the needle is covered by the guard part.

28. The method of claim 27, wherein the locks are catches positioned inside the hub on opposite sides that lock when pushed together.

29. The method of claim 28, wherein the catches lock together when said collapsible walls are collapsed.

30. The method of claim 28, wherein the catches lock the needle within the guard part.

31. The method of claim 23, wherein the needle is configured to extend through the cannula of the cannula housing and beyond an outer tip thereof when the insertion device is attached to the cannula housing.

32. The method of claim 23, wherein the guard part includes a needle recess to house the needle.

33. The method of claim 23, wherein the collapse part is composed of material that flexes without fracturing.
