  • the needle must be changed before each injection, which must be removed after the injection, and not all cartridges fit together.
  • Pre-filled disposable syringes make it easier to administer medication, which is convenient for many patients. Patients often prefer this injection method over reusable pen and conventional syringes because of the convenience and ease of use, which allows the drug to be administered without difficulty when needed.
  • the advantage of a disposable syringe pen is that it eliminates the need to insert a new cartridge into the syringe handle, as it is necessary to do in reusable syringes, which simplifies the method of drug administration (there is no need for additional preliminary manipulations associated with installing the cartridge into the pen - syringe, which takes time) and makes the injection procedure more comfortable for the patient.

Abstract

L'invention se rapporte aux dispositifs médicaux pour l'administration intramusculaire ou sous-cutanée de préparations pour injections liquides à un seul composant et concerne notamment des dispositifs permettant d'administrer des préparations médicamenteuses préalablement versées, et peut être utilisée pour des injections dans des conditions standards ou d'urgence. Cette seringue médicale à usage unique comprend un corps se présentant sous forme d'une capsule entière d'un côté (1), et comporte à l'intérieur une cloison de séparation mobile (2), une capsule de scellage (3) disposée dans le corps du côté ouvert et comportant un clapet anti-retour d'étanchéité élastique. Cette seringue médicale à usage unique comprend un mécanisme d'appui-compression (8) avec une aiguille creuse à double tranchant (7), et du côté opposé du corps est fixée une applique de protection élastique d'étanchéité (9) avec une couche de colle (10). La capsule (3) comporte une niche (4) avec une connexion au mécanisme d'appui-compression (8), et le mécanisme d'appui-compression (8) comporte une pige correspondante (5) en vue de la connexion à la capsule (3).
