Summary for Patent: 5,370,629

Title:	Injection device
Abstract:	The invention concerns an injection device (1) receiving in exchangeable manner an ampoule (4) with a plunger (5) and an injection needle (6). It further comprises an actuation means (7) essentially consisting of an operating head (8), a drive element (11), a guide element (24) and an output member (9, 19) preferably in the form of a rod (9) and flange (19). The output member is non-rotatably affixed to the guide element (11) itself rigidly mounted inside the device (1) and seated by its own thread in an internal thread (27) of the drive element (11) which can be displaced axially and into rotation by the manual operating head (8). When rotating the operating head (8), the output member (9, 19) is advanced and in the process forces forward the plunger (5), the result being injection. The stationary guide element (24) of the disclosed device is located axially ahead of the axially displaceable drive element (11). Accordingly the length of the actuation system (7) is shorter than in state-of-the-art injection devices, whereby a larger maximum dose can be injected with a device (1) of the same length. The device (1) is applicable in medicine.
