Abstract

Un stylo d'injection réglable comprend un manchon de protection intermédiaire (5) et un cylindre d'insertion de noyau médicamenteux (9). Un noyau médicamenteux (14) est ménagé dans une cavité intérieure du cylindre d'insertion de noyau médicamenteux (9), et un manchon extérieur (7) du cylindre d'insertion est disposé sur une surface extérieure du cylindre d'insertion de noyau médicamenteux (9). Un manchon de protection extérieur (3) est agencé sur une surface extérieure du manchon de protection intermédiaire (5), et un manchon d'affichage de dose (10) est ménagé entre une extrémité inférieure du manchon de protection intermédiaire (5) et le manchon de protection extérieur (3). Une extrémité inférieure du manchon d'affichage de dose (10) est reliée à une poignée (2), et un bouton (1) est disposé dans un trou traversant de la poignée (2). Un manchon de protection intérieur (4) est emmanché dans le manchon de protection intermédiaire (5), et une crémaillère (6) est emmanchée dans le manchon de protection intérieur (4). Une extrémité supérieure de la crémaillère (6) entre en contact avec un bouchon de caoutchouc (15) du noyau médicamenteux(14), des engrenages doubles (13) sont disposés dans les dents de crémaillère sur une surface intérieure de la crémaillère (6) et entrent en contact avec un siège à engrenage à une extrémité supérieure d'une tige de verrouillage (11), et l'autre extrémité de la tige de verrouillage (11) est reliée à l'extrémité intérieure du bouton (1). Un bloc de friction (12) est disposé entre la crémaillère (6) et le manchon de protection intermédiaire (5). Le stylo d'injection réglable permet de choisir la dose d'injection avec précision et rend l'utilisation et le transport pratiques.
