Definitions

  • the invention relates to an injection device with a housing in which a container with an injection liquid is arranged to be longitudinally displaceable, at the proximal end of which an injection needle can be detachably attached.
  • injection devices With injection devices, it is particularly problematic for older patients to bring these devices into a specific position before an injection, in which e.g. the dose can be set or from which an injection can be triggered.
  • an injection device with a housing in which a container for holding an injection liquid is arranged to be longitudinally displaceable, at the proximal end of which an injection needle can be detachably fastened, with a spring which is assigned a releasable locking member to lock this spring in a tensioned position, and with a tensioning element which can be inserted into the proximal end of the housing in order to displace the longitudinally displaceable container in the distal direction and thereby to bring the spring into a tensioned position.
  • the use of a tendon which is inserted into the proximal end of the housing and thereby moves the container into a tensioned position results in simple operation. At the same time, the tendon can serve as a cover cap to protect the mechanics of the injection device against contamination.
  • the contact between the tendon and the container is designed such that the spring can be locked in the tensioned position when the needle is mounted, but not when no needle is mounted. It is achieved in this way that the spring cannot be locked in the tensioned position without a needle, so that subsequent triggering of an injection by releasing the locking member is also not possible. This reminds the patient that he has to insert a new needle, because without this he cannot tighten the device and therefore cannot make a "sham injection".
  • FIG. 1 is a side view of an injection device according to the invention, in which only individual parts are shown in longitudinal section,
  • Fig. 2 is an illustration analogous to Fig. 1, but rotated by 90 ° relative to Fig. 1, and
  • FIG. 3 shows the injection device according to FIG. 2, but the patient has forgotten to mount an injection needle, which is why the injection device cannot be tightened.
  • FIG. 1 shows a side view of an injection device 10.
  • distal the side facing away from the patient, that is to say the upper side in FIG. 1.
  • the injection device 10 has a tubular housing 12, which is shown in section in FIG. 1 below.
  • a carpule container 14 is arranged longitudinally displaceably in it.
  • a cartridge 16 with injection liquid 18 is located in its interior.
  • the carpule container 16 runs down into a neck 20 on which there is an external thread 22, onto which the holder 24 of a conventional injection needle 26 can be screwed, cf. 1 and 2.
  • the neck 20 has an axial opening 30 at the bottom through which a distal section 32 of the injection needle 26 extends in order to pierce a rubber membrane 36 at the proximal end of the cartridge 16, as is known to the person skilled in the art.
  • a needle 26 If a needle 26 is mounted, its holder 24 covers the opening 30, cf. 1 and 2. If a tensioning member 40 is now inserted into the proximal end of the housing 12 for tensioning the injection device, as is particularly clearly shown in FIG. 1, a central hollow cylindrical section 42 of the tensioning member 40 lies with its distal end 44 against the Holder 24 on and moves this and the cartridge holder 14 in the distal direction.
  • the carpule holder 14 continues in the distal direction and in its distal region passes into a setting device (not shown) which is acted upon by an injection spring 50, which in FIG. 2 is only completely is indicated schematically.
  • Fig. 1 shows this spring 50 in the tensioned state.
  • the adjusting device 46 has in the distal region a latching button 52 acted upon by a spring 51, which can latch into a latching opening 54 of the housing 12 in order to latch the injection spring 50 in its tensioned position.
  • a clip 56 is attached, which with a projection 58 is provided, which presses the locking button 52 when actuated and thereby triggers an injection, as is known to the person skilled in the art.
  • the hollow cylindrical extension 42 of the tensioning member 40 penetrates the axial opening 30 of the cartridge holder 14 and comes to rest against the proximal end of the cartridge 16.
  • the adjusting device 46 (FIG. 2) is displaced less far in the distal direction, so that according to FIG. 3 the locking button 52 cannot snap into the locking opening 54, ie in this case, the injection device 10 cannot be locked in its cocked position, and an injection is not possible.
  • the tensioning member 40 can be provided with an external thread 60 which is screwed into a corresponding internal thread of the housing 12 by the patient in order to tension the injection device 10. 1 and 2, the tension member 40 covers with its extension 42 the needle 26 and protects it, and the device itself, from contamination. Before an injection, the tendon 40 is unscrewed or otherwise removed.
  • a viewing window 64 (FIG. 1) is provided in the proximal section of the housing 12 in order to be able to see the filling level of the cartridge 16.

Abstract

L'invention concerne un dispositif d'injection comportant un cylindre (12), qui contient un réservoir (14) pouvant recevoir un liquide d'injection (18) et coulisser à l'intérieur dudit cylindre;, une aiguille d'injection (26), qui peut être fixée libérable à l'extrémité proximale dudit réservoir; un ressort (50), associé à un élément d'encliquetage (52) libérable destiné à bloquer ledit ressort (50) en position tendue (fig. 2); et un élément de tension (40), qui peut être introduit dans l'extrémité proximale du cylindre (12) de façon à déplacer le réservoir (14) en direction distale et ainsi amener le ressort (50) en position tendue.
