Title (EN) DEVICE FOR AUTOMATICALLY INJECTING AN ACTIVE AGENT
(FR) DISPOSITIF D'INJECTION AUTOMATIQUE D'UNE SUBSTANCE ACTIVE
(DE) VORRICHTUNG ZUM AUTOMATISCHEN INJIZIEREN EINES WIRKSTOFFES
Abstract:
(EN) The invention relates to a syringe (50) filled with an active agent (50) and having an injection needle (37), said syringe being displaceable in a receiving part (16) by the tension of a spring. A transmission part (5) displaceable by at least one spring (11) traverses a first partial path (54) for sticking the injection needle (37) and a second partial path (55) for emptying the active agent. The at least one spring (11) acts between the transmission part (5) and an intermediate part (10) and another spring (9) acts between the intermediate part (10) and a supporting part (8) that is fixedly connected to the receiving part (16). An indicating device (12) that is visible from the outside is connected to the intermediate part (10). The indicating device (12) that is visible through a transparent part (51) moves only during the second partial course and traverses a path (56) that is substantially smaller than the sum of both partial strokes.
(FR) Une seringue (50) remplie d'une substance active et pourvue d'une aiguille d'injection (37) est coulissante grâce à une force de ressort dans une partie réceptrice (16). Une partie de transmission (5) coulissant sous l'action d'au moins un ressort (11) effectue une première course partielle (54) pour l'introduction de l'aiguille d'injection (37) et une seconde course partielle (55) pour l'évacuation de la substance active. Le ressort (11) agit entre la partie de transmission (5) et une partie intermédiaire (10) et un autre ressort (9) agit entre la partie intermédiaire (10) et une partie d'appui (8) fixée immobile sur la partie réceptrice (16). Un élément indicateur (12) visible de l'extérieur est relié à la partie intermédiaire (10). L'élément indicateur (12) visible à travers une partie transparente (51) se déplace uniquement pendant la seconde course partielle et parcourt ainsi une longueur (56) qui est considérablement plus petite que la somme des deux courses partielles.
(DE) Eine mit einem Wirkstoff gefüllte Spritze (50) mit Injektionsnadel (37) ist in einem Aufnahmeteil (16) durch Federkraft verschiebbar. Ein durch mindestens eine Feder (11) verschiebbarer Übertragungsteil (5) macht einen ersten Teilweg (54) zum Einstechen der Injektionsnadel (37) und einen zweiten Teilweg (55) zum Ausschütten des Wirkstoffes. Die mindestens eine Feder (11) wirkt zwischen dem Übertragungsteil (5) und einem Zwischenteil (10) und eine weitere Feder (9) wirkt zwischen dem Zwischenteil (10) und einem mit dem Aufnahmeteil (16) unbeweglich verbundenen Stützteil (8). Mit dem Zwischenteil (10) ist eine von aussen sichtbare Anzeige (12) verbunden. Die durch einen durchsichtigen Teil (51) sichtbare Anzeige (12) bewegt sich nur während des zweiten Teilweges und legt dabei einen Weg (56) zurück, der wesentlich kleiner ist als die Summe der beiden Teilhübe.
