摘要：
Disclosed is a needle insertion arrangement (1) with a drive mechanism (9) comprising: a belt (15) frictionally engaging a first roller (10) and a needle retainer (7) with an injection needle (2) fixed to the belt, the first roller being rotatably arranged about an axis (A), a second roller (11) also rotatably arranged about the axis (A), a first spring (13) rotatably biasing the first roller against the second roller, a second spring (14) rotatably biasing the second roller against an arrester (12), the first and the second roller being connected via an internal protrusion (10.2) and arcuate slot (11.2), the two springs (13, 14) biasing the rollers (10, 11) from respective first to respective second angular positions (AP11, AP12, AP21, AP22), and a trigger mechanism (17,20) releasably locking the first and second rollers (10, 11) such that upon pivoting the trigger button (20) in one direction, the first roller drives the belt in one direction to linearly transport the needle retainer towards an extended position, and upon pivoting the trigger button in the other direction, the first roller drives the belt back to retract the needle retainer.
