Abstract
(DE)
Ein Injektionsgerät hat einen Behälter (80) zur Aufnahme einer eine Injektionsflüssigkeit (53) enthaltenden Kartusche (52), an deren proximalem Ende eine Injektionsnadel (76) befestigbar ist. Dieser Behälter (80) ist in einem Gehäuse (50, 48, 46, 36) zwischen einer proximalen Endstellung und einer distalen Endstellung verschiebbar. In dem Gehäuse ist ein zum Auspressen von Injektionsflüssigkeit (53) aus der Kartusche (52) dienender Stössel (108) angeordnet, welcher bei einer Injektion in einem Führungsglied (124) axial verschiebbar, aber relativ zum Gehäuse unverdrehbar, geführt ist und ein Aussengewinde (159) aufweist, das in einem Innengewinde (152) eines Einstellglieds (151) geführt ist, welches zur Einstellung der Injektionsdosis dient. Zwischen dem Behälter (80) und dem Stössel (108) ist eine kraftschlüssige Kupplung (162, 250) vorgesehen, welche nach Art einer Rutschkupplung zum Übertragen mindestens eines Teils einer axialen Bewegung des Stössels (108) auf den Behälter (80) dient.
(EN)
The invention relates to an injection device comprising a container (80) which receives a cartridge (52) which contains an injection fluid (53) and to whose proximal end an injection needle (76) can be fixed. The container (80) can be displaced in a housing (50, 48, 46, 36) between a proximal and a distal terminal position. A plunger (108) for expelling injection fluid (53) from the cartridge (52) is arranged in the housing and guided in a guide member (124) such that during injection it can be axially displaced but not rotated in relation to the housing. The plunger has an external thread (159) which is guided in an inner thread (152) of an adjustment member (151) serving to control the injection dose. Between the container (80) and the plunger (108) a frictional engagement coupling (162, 250) is provided for which in the manner of a slipping coupling serves to transmit at least part of an axial movement of the plunger (108) to the container (80).
(FR)
L'invention concerne un appareil d'injection comprenant un contenant (80) servant à loger une cartouche (52) qui contient un liquide à injecter (53), une aiguille d'injection (76) pouvant être fixée à l'extrémité proximale de ladite cartouche. Ce contenant (80) peut coulisser dans un boîtier (50, 48, 46, 36) entre une position finale proximale et une position finale distale. Un piston (108) servant à faire sortir le liquide à injecter (53) de la cartouche (52), en le comprimant, est placé dans le boîtier. Ce piston peut coulisser axialement dans un organe de guidage (124) lors d'une injection, mais ne peut pas tourner par rapport au boîtier. Il présente un filetage extérieur (159) qui est guidé dans un filetage intérieur (152) d'un organe de réglage (151) servant à régler la dose à injecter. Un accouplement par liaison de force (162, 250) situé entre le contenant (80) et le piston (108) sert, à la manière d'un accouplement à friction, à transférer au moins une partie d'un mouvement axial du piston (108) au contenant (80).
