Claim:
1. An insertion device comprising: an insertion needle holder, a drive mechanism for linearly moving the insertion needle holder in a puncturing direction, wherein the drive mechanism includes a rotor and a connecting rod, wherein the rotor includes a toothed wheel and wherein the connecting rod is coupled to the rotor at the first end of the connecting rod, the connecting rod further extending from the first end to an opposite second end that is coupled to the insertion needle holder, and at least one gripping arm extending transversely or opposite to the puncturing direction that is coupled in meshed relationship to the toothed wheel of the rotor so that movement of the at least one gripping arm sets the rotor of the drive mechanism in motion, wherein the drive mechanism converts a driving motion of the at least one gripping arm into a rotary motion of the rotor and the rotary motion of the rotor is converted into a linear motion of the connecting rod which moves the insertion needle holder in the puncturing direction, wherein the at least one gripping arm and the drive mechanism are configured so that movement of the insertion needle holder in the puncturing direction occurs during the driving motion of the at least one gripping arm and wherein the drive mechanism converts the driving motion of the at least one gripping arm into retraction motion of the insertion needle holder immediately after the puncturing motion.
