Abstract

A medical device includes a body and a cannula extending from the body, for insertion into a patient'"'"'s skin. The medical device also includes a guard covering the cannula, an adhesive for securing the medical device to the patient'"'"'s skin, and an adhesive liner covering the adhesive. The guard is connected to the adhesive liner to enable conjoint and at least partial removal of the guard and the adhesive liner.

Claims

1. A medical device, comprising:

a body;

a cannula extending from the body, for insertion into a patient'"'"'s skin;

a guard covering the cannula;

an adhesive for securing the medical device to the patient'"'"'s skin; and

an adhesive liner covering the adhesive;

wherein the guard is connected to the adhesive liner to enable conjoint and at least partial removal of the guard and the adhesive liner.

2. The medical device according to claim 1, wherein the guard comprises:

a guarding portion for covering the cannula; and

a connecting portion for connecting the guard to the adhesive liner.

3. The medical device according to claim 2, wherein the connecting portion comprises at least one arm extending from the guarding portion.

4. The medical device according to claim 3, wherein the connecting portion comprises a plurality of arms.

5. The medical device according to claim 3, wherein the arm is substantially straight.

6. The medical device according to claim 3, wherein the arm is curved.

7. The medical device according to claim 6, wherein the arm has an S-shape.

8. The medical device according to claim 2, wherein the connecting portion comprises a disc.

9. The medical device according to claim 8, wherein the disc has cutout portions.

10. The medical device according to claim 4, wherein the arms are joined by at least one web portion.

11. The medical device according to claim 1, wherein:

the adhesive liner has a slit; and

the guard is connected to the adhesive liner at or adjacent to the slit.

12. The medical device according to claim 2, wherein:

the adhesive liner has a slit;

the connecting portion is connected to the adhesive liner at or adjacent to the slit; and

the shape of the slit corresponds to the shape of the connecting portion.

13. The medical device according to claim 2, wherein the guarding portion is enclosed.

14. The medical device according to claim 1, wherein at least one of the adhesive liner and the guard has an indicator indicating a direction for removal.

15. The medical device according to claim 1, wherein the guard is connected to the adhesive liner by one of double-sided tape and an adhesive.

16. The medical device according to claim 1, wherein the conjoint and at least partial removal of the guard and the adhesive liner is substantially simultaneous.

17. The medical device according to claim 1, wherein the guard and the adhesive liner are directly joined to each other.

18. The medical device according to claim 1, wherein the adhesive liner constitutes at least one segment of a multi-segment liner covering the adhesive.

19. The medical device according to claim 1, wherein during the conjoint and at least partial removal of the guard and the adhesive liner, there is a time delay between the and at least partial removal of one of the guard and the adhesive liner and the and at least partial removal of the remaining one of the guard and the adhesive liner.

20. A method of preparing a medical device for insertion into a patient'"'"'s skin, comprising:

conjointly and at least partially removing a cannula guard and an adhesive liner from the medical device.

21. The method according to claim 20, wherein the guard and the adhesive liner are directly joined to each other.

22. The method according to claim 20, wherein the conjoint and at least partial removal of the guard and the adhesive liner is substantially simultaneous.

23. The method according to claim 20, wherein there is a time delay between the at least partial removal of one of the guard and the adhesive liner and the at least partial removal of the remaining one of the guard and the adhesive liner.

24. A method of preparing a medical device for insertion into a patient'"'"'s skin, comprising:

providing a guard for covering an insertable cannula of the medical device;

providing an adhesive liner for protecting an adhesive surface and/or adhesive pad of the medical device; and

connecting the needle guard to the adhesive liner so that removal of one of the guard and the adhesive liner from the medical device also at least partially removes the remaining one of the guard and the adhesive liner.

25. The method according to claim 24, wherein connecting the needle guard and the adhesive liner comprises applying adhesive means to at least one of the needle guard and the adhesive liner.

26. A protector for a medical device, comprising:

a guard for guarding a cannula of the medical device; and

an adhesive liner for covering an adhesive for securing the medical device to the patient'"'"'s skin;

wherein the guard is connected to the adhesive liner to enable conjoint and at least partial removal of the guard and the adhesive liner.

27. The protector according to claim 26, wherein the guard comprises:

a guarding portion for guarding the cannula; and

a connecting portion for connecting the guard to the adhesive liner.

28. The protector according to claim 26, wherein:

the adhesive liner has a slit; and

the guard is connected to the adhesive liner adjacent to the slit.

29. The protector according to claim 26, wherein the at least partial conjoint removal of the guard and the adhesive liner is substantially simultaneous.

30. The protector according to claim 26, wherein the guard and the adhesive liner are directly joined to each other.

31. A method of preparing a medical device for insertion into a patient'"'"'s skin, comprising:

installing the medical device into an insertion device; and

subsequent to such installation, conjointly and at least partially removing a cannula guard and an adhesive liner from the medical device.
