INSERTER DEVICE WITH CONTROLLED ACCELERATION
First Claim
1. An inserter device for inserting a penetrating member into the subcutaneous and/or intramuscular area of a patient, said inserter device comprising:
- a housing encompassing a penetrating member, the penetrating member comprising a soft cannula and an introducer needle, the introducer needle comprising part of the inserter device,a rotating member, the rotating member comprising transformation means transforming the rotational movement into a longitudinal movement of the penetrating member in a direction of insertion and the transformation means comprises controlling means providing a controlled variation of a velocity of the penetrating member in the direction of insertion;
and driving means for rotating the rotating member around a rotating axis;
wherein continued rotation of the rotating member in the same direction of rotation or rotation of the rotating member in the opposite direction of rotation after insertion of the penetrating member provides that insertion of the penetrating member is followed by retraction of the introducer needle.

Abstract
The invention concerns an inserter device for inserting a medical device into the subcutaneous or intramuscular area of a patient. More specifically, this invention relates to an inserter device comprising means for providing a controlled and defined acceleration and deceleration of a penetrating member. The inserter device (200, 500) according to the invention comprises a housing (201, 221, 251; 501, 502, 503) encompassing said penetrating member (105, 243), a rotating member (204, 300, 400, 512) and driving means (203, 561) for rotating the rotating member (204, 300, 400, 512) around a rotating axis. The rotating member (204, 300, 400, 512) comprises transformation means (216, 246, 521) transforming the rotational movement into a longitudinal movement of the penetrating member (105, 243) in the direction of insertion and the transformation means (226, 246, 521) comprises controlling means providing a controlled variation of the velocity of the penetrating member (105, 243) in the direction of insertion.
