Abstract

The present invention relates to a device comprising a transcutaneous device and an inserter which transcutaneous device has a mounting surface. The device is upon delivery arranged in a sterile packing which packing functions as inserter and is attached to the transcutanous device i.e. the packing and the inserter is one integrated unit. A device according to the present invention comprises a transcutaneous device (1) and an inserter (2). The transcutaneous device comprises—a mounting part (13) having a mounting surface (14),—a soft cannula (6)—a fluid path leading fluid from a fluid source to the soft cannula (6),—means for releasably attaching the transcutaneous device (1) to the inserter (2). The inserter (2) comprises—a cover providing an at least partly protection against the surroundings for the distal side of the transcutaneous device (1) at least before insertion of the soft cannula (6),—means for releasably attaching the inserter (2) to the transcutaneous device (1),—an insertion needle (5),—at least one handle (3, 4) for loading and releasing of the insertion needle (5),—at least one elastic member (19, 22) which is loaded upon activation of the at least one handle (3, 4) and afterwards released.

Claims

1. A device comprising:

a transcutaneous device comprising;

a mounting part having a mounting surface,

a soft cannula

a fluid path leading fluid from a fluid source to the soft cannula, and

an inserter comprising;

a cover at least partly providing protection against the surroundings for a distal side of the transcutaneous device at least before insertion of the soft cannula,

means an attachment member for releasably attaching the inserter to the transcutaneous device,

an insertion needle,

at least one handle for loading and releasing of the insertion needle,

at least one elastic member which is loaded upon activation of the at least one handle and afterwards released and

wherein the transcutaneous device comprises an attachment member for releasably attaching the transcutaneous device to the inserter.

2. The device according to claim 1, wherein the device comprises two elastic members, a first elastic member that can force the insertion needle into the transcutaneous position when released and a second elastic member that can retract the insertion needle from the transcutaneous position when released.

3. The device according to claim 1, wherein the at least one handle comprises two handles where a first handle is used to load a first elastic member and a second handle is used to release the same first elastic member.

4. The device according to claim 1, wherein the protective cover is made of a hard material having openings for one or more handles.

5. The device according to claim 1, wherein the cover has an opening adapted for receiving a delivery unit comprising a pump, a reservoir for fluid and a controller in order to attach the delivery unit to the transcutaneous device.

6. The device according to claim 3, wherein the inserter comprises a sliding part connected to the first handle and a contact part connected to the second handle, further the sliding part is connected to the contact part via the first elastic member.

7. The device according to claim 6, wherein the second handle releases a locking part preventing the contact part from moving towards the sliding part.

8. The device according to claim 6, wherein the first elastic member consists of a rubber band or another spring which is loaded upon expansion.

9. The device according to claim 6, wherein contact part comprises a part having a contact surface pushing against a surface of a needle holder holding the insertion needle.

10. The device according to claim 1, wherein the soft cannula of the transcutaneous device is attached to a cannula part and the cannula part is connected to the reservoir after insertion in a fluid tight connection.

11. The device according to claim 10, wherein the fluid tight connection to the reservoir is obtained after insertion, the cannula part or a cannula holder or both is/are provided with a gasket.

12. The device according to claim 10, wherein the cannula part is connected to a stationary connector part with a flexible or movable connection so that the fluid tight connection to the reservoir is obtained both before and after insertion.

13. The device according to claim 12, wherein the movable connection can be pivoted relative to the mounting part.

14. The device according to claim 12, wherein the flexible connection comprises a soft tube connected to the inlet of the cannula part and to the outlet of the connector part.

15. The device according to claim 1, wherein the transcutaneous device comprises longitudinal rails corresponding to grooves or hooks on the inserter.

16. The device according to claim 1, wherein the fluid source is a reservoir attached to the mounting part.

17. The device according to claim 16, wherein the reservoir contains a medication.

18. The device according to claim 1, wherein an insertion point for the cannula is separated from a main part of the mounting part by a flexible band of a compliant material.

19. The device according to claim 17, wherein the medication comprises insulin.
