Definitions

  • the internal portion and the external portion of the indication sleeve are made of different materials.
  • fig. 2 the assembled mechanism of fig. 1 is shown.
  • the indication sleeve 3 and the push-pull nut 4 are mounted on the control sleeve 2, and all of three sleeves are located within the housing 7.
  • the proximal end of the control sleeve (to be engaged with a knob 11 of the injection device - see fig. 5) may be seen near the proximal end 7a of the housing 7 in fig. 2.
  • the indication sleeve 3 is engaged with the collar 4.3 of the push-pull nut 4 by means of internal projections 3.1.
  • the operating assembly may be released by activating the triggering assembly in order to deliver the dose.
  • the operation of the triggering assembly will be described below.
  • the automatic applicator comprises three main assemblies connected by a nut 28 having a twist-type double-start thread: the operating part comprising an enclosure 8 for a disposable pharmaceutical substance cartridge into which a piston 9 is introduced, the dosing-driving mechanism and the trigger assembly.

Abstract

Un mécanisme d'indication (1) pour un dispositif d'injection pour administrer des doses réglables d'une substance pharmaceutique, comprenant un manchon de commande rotatif (2) sur lequel sont montés un manchon d'indication (3) et un écrou de poussée-traction (4), le manchon d'indication (3) étant pourvue de repères (5), qui sont visibles par un utilisateur et qui sont en prise en rotation avec le manchon de commande (2) et qui peuvent être déplacés le long du manchon de commande (2), l'écrou de poussée-traction (4) ne pouvant pas se mettre en rotation et étant en prise en translation avec le manchon d'indication (3) et coopérant par filetage avec le manchon de commande (2), dans lequel le manchon d'indication (3) comprend une partie externe (3a) et une partie interne (3b), la surface interne de la partie interne (3b) étant conçue pour faciliter la translation du manchon d'indication (3) le long du manchon de commande (2), et la surface externe de la partie externe (3a) étant conçue pour faciliter l'application des repères (5) sur celle-ci.
