This application is a continuation of U.S. application Ser. No. 12/480,055, filed Jun. 8, 2009, now U.S. Patent No. 8,070,722, which is a divisional of U.S. application Ser. No. 11/050,101, filed Feb. 3, 2005, now U.S. Pat. No. 7,704,229, and is related to U.S. application Ser. No. 13/276,935, filed Oct. 19, 2011, and to a non-provisional U.S. Application entitled “INSERTION DEVICE”, which is being filed concurrently herewith, all of which are incorporated herein by reference in their entirety.
Insertion devices are generally used in the field of subcutaneous infusion sets. These infusion sets are used for delivering a fluid, medication or other infusant, for example, insulin, to a subcutaneous site in a patient. Such an infusion set is described, for example, in U.S. Pat. Nos. 6,520,938 and 6,056,718, which are herein incorporated by reference. Another example is described in co-pending U.S. application Ser. No. 11/003225, entitled Medication Infusion Set, filed on Dec. 3, 2004, which is herein incorporated by reference. These devices commonly include a delivery tube connected to an infusion pump or other fluid or medication delivering device. Such an infusion set may include a base portion with a cannula deposited in the skin of a patient, and an adhesive patch at the base of the cannula housing to hold the cannula in place. The cannula is inserted into the skin of a patient, with the aid of an insertion device, to facilitate the subcutaneous transfer of an infusant. The possibility of disconnecting the infusion set from other parts of the infusion system is provided in order to improve the user comfort.
a needle attached to the hub; and
a collapse part attached to the handle part and having two opposing and parallel 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 to cover the needle.
5. The insertion set of claim 4, 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. The insertion set of claim 1, wherein said walls collapse along the line of application of said pressure to said collapse part.
13. An insertion device, comprising:
14. The insertion device of claim 13, wherein the handle part is disposed between the collapse part and the guard part.
15. The insertion device of claim 13, further including a push block connected to the collapse part.
16. The insertion device of claim 15, 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 to cover the needle.
17. The insertion device of claim 16, further including locks adapted to secure the needle in the guard part when the needle is covered by the guard part.
18. The insertion device of claim 17, wherein the locks are catches positioned inside the hub on opposite sides that lock when pushed together.
19. The insertion device of claim 18, wherein the catches lock together when said collapsible walls are collapsed.
20. The insertion device of claim 18, wherein the catches lock the needle within the guard part.
21. The insertion device of claim 13, 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.
22. The insertion device of claim 13, wherein the guard part includes a needle recess to house the needle.
23. The insertion device of claim 13, wherein the collapse part is composed of material that flexes without fracturing.
24. The insertion device of claim 13, wherein said walls collapse along the line of application of said pressure to said collapse part.
25. A method for covering an insertion needle, comprising:
a collapse part attached to the handle part and having two opposing and parallel collapsible walls that are biased to improve collapse of both walls when pressure is applied to the collapse part;
26. The method of claim 25, wherein the handle part is disposed between the collapse part and the guard part.
27. The method of claim 25, wherein the insertion device further includes a push block connected to the collapse part.
28. The method of claim 27, 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 to cover the needle.
29. The method of claim 28, 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.
30. The method of claim 29, wherein the locks are catches positioned inside the hub on opposite sides that lock when pushed together.
31. The method of claim 30, wherein the catches lock together when said collapsible walls are collapsed.
32. The method of claim 30, wherein the catches lock the needle within the guard part.
33. The method of claim 25, 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.
34. The method of claim 25, wherein the guard part includes a needle recess to house the needle.
35. The method of claim 25, wherein the collapse part is composed of material that flexes without fracturing.
36. The method of claim 25, wherein said walls collapse along the line of application of said pressure to said collapse part.
