Abstract:
An injection device for actuating a syringe, in particular a disposable syringe, with drive and control means which are held in a housing and which cause the injection operation to take place successively in such a way that first a linear displacement of the syringe (1) with the injection needle takes place for introducing the injection needle into the skin, and then the injection of the injection fluid takes place, and the drive and control means contain a control sleeve (6) which is displaceable between a closing and operating position (P1), which prevents access to the syringe (1) and releases a trigger means for the injection operation, and an opening and securing position (P2), which allows the syringe (1) to be inserted and extracted,characterized in that the control sleeve (6), over part of its circumference, has a loading orifice (L6) for inserting and extracting the syringe (1), and that it is rotatable between the closing and operating position (P1) and the opening and securing position (P2) by a control angle (a) on the casing surface (M) of the housing (7).
