Abstract

A housing may have a needle, plunger, and bias mechanism supported within the housing by a tab configured to retain the plunger in position and to allow the plunger to move under bias force imparted by the bias mechanism to move the needle to an insert position when the tab is removed. A base and a structure may be configured for relative movement there between and may be adapted to be secured to a user with a cannula extending through a body of the structure into the user during use of a medical device. A housing may be adapted to be secured to a user to support a medical device operable with an insertion needle, the housing having a magnifying material for increasing visibility of an injection site.

Claims

1-17. -17. (canceled)

18. A medical device, the device comprising:

a medical monitoring or treatment device configured to provide a monitoring or treatment operation on a user;

a base adapted to be secured to the user during operation of the medical monitoring or treatment device;

a structure adapted to be secured to the user during operation of the medical monitoring or treatment device, the structure connected to and supported by the base, the structure having a body, the structure and the base configured for relative movement there between; and

a cannula extending through the body of the structure during operation of the medical monitoring or treatment device, the cannula for inserting into the user during operation of the medical monitoring or treatment device.

19. The medical device of claim 18, the structure arranged to be separate and apart from the base.

20. The medical device of claim 18, the structure operatively connected to the base.

21. The medical device of claim 18, the device further comprising:

a flexible connection connecting the base and the structure

22. The medical device of claim 21,

at least one of the base, the structure, and the cannula placeable by an insertion device;

the flexible connection adapted to release the insertion device after placement of the at least one of the base, the structure, and the cannula.

23. The medical device of claim 21,

wherein the flexible connection comprises a living hinge connecting the base and the structure.

24. The medical device of claim 18, the device further comprising:

a bias member provided between the base and the structure.

25. The medical device of claim 18, the device further comprising:

a fluid connection in fluid communication with the cannula and a reservoir containing fluidic media.

26. The medical device of claim 25, wherein the fluid connection comprises a flexible tubing.

27. The medical device of claim 18, the device further comprising:

a housing, the base, and the structure adapted to fit within the housing.

28. The medical device of claim 18,

the base having an interior chamber;

wherein the cannula is supported within the interior chamber of the base.

29. The medical device of claim 18,

the base having an interior chamber;

wherein the structure is supported within the interior chamber of the base.

30. The medical device of claim 18,

wherein the base has a base surface facing skin of the user during operation of the medical monitoring or treatment device;

wherein the base has an opening through the base surface; and

wherein the structure is supported at least partially within the opening.

31. The medical device of claim 30,

wherein the structure has an inserting surface facing skin of the user during operation of the medical monitoring or treatment device;

wherein an adhesive material provided on at least a portion of the base surface and at least a portion of the inserting surface for securing the at least one of the base and the structure to the user, the adhesive material having a different adhesion strength on the structure than on the base.

32. The medical device of claim 18, the device further comprising:

an adhesive material provided on at least a portion of the structure and at least a portion of the base for securing the at least one of the base and the structure to the user, the adhesive material having a different adhesion strength on the structure than on the base.

33. The medical device of claim 18, the device further comprising:

an adhesive material provided on at least a first portion of the structure and at least a second portion of the structure for securing the structure to the user, the adhesive material having a different adhesion strength on the first portion than on the second portion.

34. The medical device of claim 18, the device further comprising:

an adhesive material provided on at least a first portion of the base and at least a second portion of the base for securing the base to the user, the adhesive material having a different adhesion strength on the first portion than on the second portion.

35. The medical device of claim 18, at least one of the base, the structure, and the cannula placeable by an insertion device.

36. The medical device of claim 18, wherein the structure comprises a sensor for sensing a parameter of the user during operation of the medical monitoring or treatment device.

37. The medical device of claim 18, the device further comprising:

a sensor for sensing a parameter of the user during operation of the medical monitoring or treatment device, the sensor operatively connected to and supported by the structure.

38. A method of making a medical device, the method comprising:

providing a medical monitoring or treatment device configured to provide a monitoring or treatment operation on a user;

providing a base adapted to be secured to the user during operation of the medical monitoring or treatment device;

providing a structure adapted to be secured to the user during operation of the medical monitoring or treatment device, the structure connected to and supported by the base, the structure having a body; and

providing a cannula extending through the body of the structure during operation of the medical monitoring or treatment device, the cannula for inserting into the user during operation of the medical monitoring or treatment device;

wherein the structure and the base are configured for relative movement there between.
