1. An infusion device comprising:
- a housing;
a cavity within the housing;
a soft cannula extending from the housing and being in flow communication with the cavity, said soft cannula having an outer tip;
a medication bore within the housing for leading medication to said cavity;
a puncturing device adapted to be connected to said housing, said puncturing device comprising a rigid needle being adapted to extend through the cannula and beyond the outer tip thereof when the puncturing device is connected to said housing, said rigid needle being at one end adapted for facilitating puncturing and including at the opposite end a hub;
said hub having a hinge, a handle part and a single shield part with a first end and a second free end, said first end of the shield part being pivotably connected to the handle part by means of said hinge, whereby said second free end is pivotable with respect to said hinge;
said shield part being adapted to cover the rigid needle when pivoted with respect to said hinge, the second free end of the shield part extending beyond said one end of the rigid needle; and
said hub further having a locking mechanism on the shield part and the handle part, the locking mechanism being adapted to interlock the shield and the handle part in a pivoted position of the shield part when the puncturing device is disconnected from the housing and the shield part is pivoted to cover the rigid needle.

23. An infusion device comprising:
-
a housing;
a cavity within the housing;
a soft cannula extending from the housing and being in flow communication with the cavity, said soft cannula having an outer tip;
a bore for leading medication to said cavity;
a puncturing device adapted to be connected to said housing, said puncturing device comprising a needle being adapted to extend through the cannula and beyond the outer tip thereof when the puncturing device is connected to said housing, said needle being at one end adapted for facilitating puncturing and comprising an opposite end of a hub;
said hub comprising a handle part and a shield part, said shield part being pivotable in relation to the handle part;
said hub further comprising a locking mechanism on the shield part and the handle part, the locking mechanism being adapted to interlock the shield and the handle part in a pivoted position of the shield part when the puncturing device is disconnected form the housing, whereby the rigid needle is covered by the shield; and
wherein the needle is bendable when the shield part and the handle part are locked together, whereby the bendable needle provides a biasing effect between the locking mechanism on the shield part and the handle part, and whereby the bendable needle closely abuts on the shield to ensure that unintended contact with the needle is avoided.
