1. An insertion device for infusion sets, said insertion device comprising:
- a housing for enclosing an infusion set;
a drive device comprising a drive endpiece for displacing the infusion set for insertion;
at least one rotary connection member on a side wall of the housing;
at least one leg lever connected at a first end to the at least one rotary connection member;
an elastic member for pretensioning the at least one leg lever against the side wall, a second end of the at least one leg lever remote from the first end for receiving the infusion set or striking the infusion set out of a holding fixture, the at least one leg lever pivoted via at least one rotary connection member when the tension of the elastic member is removed by a release mechanism; and
an infusion set holder configured to hold the infusion set within the insertion device such that the infusion set is entirely spaced-apart from the housing, and such that prior to actuation of the insertion device, the infusion set is arranged proximate the drive endpiece and configured to enable the drive endpiece to pass the infusion set holder without contacting the holder and, upon actuation of the insertion device, the drive endpiece carries the infusion set to release the infusion set from the holder.

8. An insertion device for piercing devices such as infusion sets, said device comprising:
-
a housing for enclosing a piercing device to be placed in the insertion device; at least one rotary connection member on a side wall of the housing; at least one leg lever connected at a first end to the at least one rotary connection member; an elastic member for pretensioning the at least one leg lever against the side wall, a second end of the at least one leg lever remote from the first end for receiving an infusion set or striking an infusion set out of a holding fixture, the at least one leg lever pivoted via at least one rotary connection member when the tension of the elastic member is removed by a release mechanism; a drive device for moving the piercing device in an insertion direction; and a piercing device holder configured to hold the piercing device prior to actuation of the insertion device such that the piercing device is entirely spaced-apart from the housing, wherein the piercing device holder is configured to enable a portion of the drive device to pass the piercing device holder upon actuation of the insertion device without contacting the holder and, upon actuation of the insertion device, the drive device movement in the insertion direction carries the piercing device to release the piercing device from the holder. - View Dependent Claims (9, 10, 11, 12, 13)

14. An insertion device for infusion sets, said insertion device comprising:
-
a housing for enclosing an infusion set; a drive device comprising a drive endpiece for displacing the infusion set for insertion; and an infusion set holder comprising at least two receiving elements within the insertion device configured to hold the infusion set between the at least two receiving elements such that, prior to actuation of the insertion device, the infusion set is entirely spaced-apart from the housing, and the infusion set is arranged proximate the drive endpiece and configured to enable the drive endpiece to pass between the at least two receiving elements without contacting the at least two receiving elements and, upon actuation of the insertion device, the drive endpiece carries the infusion set to release the infusion set from the at least two receiving elements; and wherein at least two first oppositely turning rotary connection members are movable in the insertion direction, and their drive movement is synchronized by the coupled rotational movement of two second positionally fixed rotary connection members, one of the first rotary connection members in each case being connected to one of the second rotary connection members via a leg lever.
