Abstract
An injection device that is used with a syringe, wherein the injection needle of the syringe is initially introduced into the skin and the injection fluid is injected afterwards. The injection device is essentially driven and controlled by a control sleeve ( ) which can be displaced and/or rotated in relation to the housing ( ) and which can be moved between a closing and functional position (P ) and an open and safety position (P ). In the closing and functional position, the control sleeve prevents access to the syringe and activates a release device for the injection process. In the open and safety position, a syringe ( ) can be removed or inserted. A plurality of components carrying out the injection process (a slide ( ) in which the syringe ( ) is placed and a plunger ( ) that impinges upon the syringe piston) are moved or controlled depending on the movement and position of the control sleeve or supported (for example, an ejection device for the syringe or a signaling device informing that injection has been completed). The device enables full-automatic injection that can be reliably carried out by patients themselves with few handling procedures.
