Retraction means for transcutaneous device
First Claim
1. A medical device, comprising:
- a lower mounting surface adapted for application towards the skin of a subject,a sheet member extending peripherally relative to the mounting surface and having a lower adhesive surface for securing the mounting surface relative to the skin,a transcutaneous device adapted to penetrate the skin of the subject and being mounted for movement between an extended position in which the transcutaneous device projects relative to the lower mounting surface and a retracted position in which the transcutaneous device is retracted relative to the lower mounting surface,a release attached directly to a peripheral portion of the sheet member, the release comprising a user gripable portion moveable relative to the lower mounting surface, the user gripable portion being operatable from a first condition through an intermediate condition to a second condition,whereby operation of the user gripable portion from the first to the intermediate condition causes the transcutaneous device to be moved from the extended position to the retracted position, and operation of the user gripable portion from the intermediate to the second condition causes release of the sheet member from the skin.

Abstract
The invention provides a transcutaneous medical device (502, 250, 150, 600) comprising a lower surface adapted for application towards the skin of a subject, attaching means (571, 272, 161) for securing the lower surface relative to the skin, and a transcutaneous device (530, 182, 213, 651) adapted to penetrate the skin of the subject. The transcutaneous device is mounted for movement between an extended position in which the transcutaneous device projects relative to the lower surface and a retracted position in which the transcutaneous device is retracted relative to the lower surface. The medical device further comprises release means (550, 275, 162) which can be operated from a first state through an intermediate state to a second state, whereby operation of the release means from the first to the intermediate state causes the transcutaneous device to be moved from the extended position to the retracted position, and operation of the release means from the intermediate to the second state causes release of the attaching means.

19. A medical device comprising:
-
a mounting surface adapted for application to a skin site, a sheet member extending peripherally relative to the mounting surface and having a lower adhesive surface for securing the mounting surface relative to the skin an adhesive for securing the mounting surface to the skin site, —
a transcutaneous device adapted to penetrate the skin at the skin site, the transcutaneous device being mounted for movement between an initial position in which the transcutaneous device is retracted relative to the lower surface and an extended position in which the transcutaneous device projects relative to the lower surface, and for movement between the extended position and a retracted position in which the transcutaneous device is retracted relative to the lower surface,actuation means comprising a first user gripable portion moveable relative to the mounting surface, the first user gripable portion being moveable to cause the transcutaneous device to be moved from the initial position to the extended position, and a release attached directly to a peripheral portion of the medical device and comprising a second user gripable portion moveable relative to the housing, the second user gripable portion being moveable to cause the transcutaneous device to be moved from the extended position to the retracted position, the release further allowing a pulling force to be applied to the peripheral portion of the medical device to thereby remove the medical device when secured to the skin site, wherein the release is attached to a peripheral portion of the sheet member, wherein in an initial state the first user gripable portion at least partially covers the second user gripable portion, such that the second user gripable portion is exposed when the first user gripable portion is moved to cause the transcutaneous device to be moved from the initial position to the extended position. - View Dependent Claims (21)

20. A medical device comprising:
-
a mounting surface adapted for application towards a skin site, a sheet member extending peripherally relative to the mounting surface and having a lower adhesive surface for securing the mounting surface relative to the skin a transcutaneous device adapted to penetrate the skin at the skin site, the transcutaneous device being mounted for movement between an initial position in which the transcutaneous device is retracted relative to the lower surface and an extended position in which the transcutaneous device projects relative to the lower surface, and for movement between the extended position and a retracted position in which the transcutaneous device is retracted relative to the lower surface, actuation means comprising a first user actuatable portion being actuatable to cause the transcutaneous device to be moved from the initial position to the extended position, and release means comprising a second user actuatable portion actuatable to cause the transcutaneous device to be moved from the extended position to the retracted position, wherein the release means cannot be actuated before the actuation means has been actuated and wherein the release means is attached directly to a peripheral portion of the sheet member.

22. A medical device comprising:
-
a mounting surface for mounting the device towards the skin of a user; a sheet member extending peripherally relative to the mounting surface and having a lower adhesive surface for securing the mounting surface relative to the skin a transcutaneous device for penetrating the skin of the user, the transcutaneous device being moveable between an extended position and a retracted position; a release comprising a user graspable potion, the user graspable portion being moveable to cause the transcutaneous device to be moved from the extended position to the retracted position, the release further being coupled to the medical device in a manner that allows the user to exert a force on the medical device to remove the medical device away from the user'"'"'s skin after the transcutaneous device has been moved from the extended position to the retracted position, wherein the release is attached directly to a peripheral portion of the sheet member. - View Dependent Claims (23)

24. An apparatus comprising:
-
a surface, a sheet member extending peripherally relative to the surface and having a lower adhesive surface for securing the surface relative to the skin a transcutaneous device adapted to penetrate the skin of a subject, the transcutaneous device being moveable between an extended position in which the needle projects relative to the surface and a retracted position in which the needle is retracted relative to the surface, a coupling for releasably securing the transcutaneous device unit to a mating structure, a release operatable from a first state through an intermediate state to a second state, wherein operation of the release from the first to the intermediate state causes the transcutaneous device to be moved from the extended position to the retracted position, and operation of the release from the intermediate to the second state causes release of the coupling and wherein the release is attached directly to a peripheral portion of the sheet member.
