Definitions

  • Syringes are frequently used in clinical medicine to administer injections, infuse intravenous therapy into the bloodstream, apply compounds such as glue or lubricant.
  • epinephrine is used as a complement, because of its bronchodilating features, but studies has showed that epinephrine does not only help the patient by clearing airways and raise blood sugar, but to inhibit the mast cell itself 14 ' 15 .
  • histamine can't be released (or at least not in the same amount) and because of the fast metabolic nature of epinephrine (together with the way of administration), the patient gets a faster and safer recovery.
  • the invention is further based on the insight that it may be an advantage to inject the liquid into the hypoderm tissue in a certain angle. This increases the areas where the auto-injector may be placed and the ares of use. For example, intramuscular injections need to be deeper than subcutaneous and need to be made in a steeper angle > 45 degrees against the underlying tissue. Subcutaneous injections, such as insulin made on the stomach between the navel and the symphysis for example, are suitable to be made in less angle, 10-30 degrees.
  • the invention is also based on the insight that a combined treatment of several different drugs may have therapeutic advantages compared to injection of a single drug.
  • One preferable combination is a corticosteroid e.g betapred in one syringe and adrenaline in the other. Or adrenaline and one anti-histamine.
  • a device as defined by the claim in 1-15 comprising separate triggers for each syringe.

Abstract

La présente invention concerne un auto-injecteur plat destiné à être déplié dans sa position d'injection, comprenant une ou plusieurs seringues pré-remplies, l'aiguille (10) ayant la longueur et le calibre appropriées pour une injection intramusculaire de la substance pré-remplie (3). Un élément de déclenchement (9) libère un ressort comprimé (12) avec son propre logement (4) qui pousse l'aiguille (10) pour pénétrer dans une couche mince potentielle de matière plastique (8) sur la peau de l'utilisateur pour atteindre une profondeur intramusculaire. Le boîtier (7) fixe les composants de telle sorte qu'aucune injection non intentionnelle ne se produit. Une poignée (6) ouvre le boîtier et déplie l'auto-injecteur. Des mécanismes de type charnière (2) sont reliés au boîtier (7) d'une manière qui rend la seringue fixée, mais toujours mobile dans un mouvement perpendiculaire. Un mécanisme d'accrochage (5) maintient le support surélevé. Une pièce (1) peut fixer le boîtier au corps. Après l'injection, l'aiguille (10) est retirée par retrait de la seringue hors de la peau et/ou par retrait complet du dispositif.
