Abstract:
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 from outside the housing to said cavity; a puncturing device adapted to be connected to said housing, said puncturing device comprising a needle and a hub, said needle mounted at one end to the hub and 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 an opposite end adapted for facilitating puncturing; said hub having a handle part and a shield part, said shield part being pivotable in relation to the handle part; said hub further including 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, whereby the needle is covered by the shield; and wherein the needle is bent by the shield when the shield part is pivoted in relation to the handle part, whereby the bent needle provides a biasing effect between the locking mechanism on the shield part and the handle part, and whereby the bent needle closely abuts on the shield to ensure that unintended contact with the needle is avoided.
