Abstract

L'invention concerne un dispositif d'injection d'échantillons de substances pour des injections sous-cutanées de liquides, comprenant : a) un corps de base fixe (1) pourvu d'une surface externe, d'une extrémité d'accouplement, d'un passage interne ; b) une ampoule à torsion de 90°, appropriée pour une fermeture de type baïonnette ; et c) un mécanisme d'injection pourvu d'un ressort incorporé, qui mesure la force d'injection, entraînée par le ressort interne, pour libérer une administration de médicament indépendamment de la dose.
