Abstract

La présente invention concerne une aiguille d'insuline de sécurité, comprenant : un support d'aiguille; une base de raccordement de tube d'aiguille à l'intérieur du support d'aiguille; une aiguille de ponction de stylo à insuline et une aiguille d'injection d'insuline disposées respectivement au niveau d'une partie supérieure et d'une partie inférieure de la base de raccordement de tube d'aiguille; un support autobloquant disposé à l'autre extrémité du support d'aiguille, une extrémité du support autobloquant étant emmanchée dans l'autre extrémité du support d'aiguille; un cylindre de poussée à l'intérieur du support autobloquant, une extrémité du cylindre de poussée étant située dans une cavité du support d'aiguille et pénétrant à travers la base de montage du tube d'aiguille devant se situer à l'intérieur de la partie de raccordement, et l'autre extrémité du cylindre de poussée étant pressée contre un clapet autobloquant sur la paroi d'une cavité à l'intérieur du support autobloquant; une protection d'aiguille ayant une extrémité raccordée à une ouverture à l'autre extrémité du support autobloquant, l'autre extrémité de la protection d'aiguille étant en suspension et la protection d'aiguille étant raccordée à la cavité dans le support d'aiguille par un ressort. Une structure d'aiguille d'injection de sécurité intégrée est utilisée, l'aiguille de la seringue d'insuline est manchonnée par la protection contractile élastique, et le déplacement de la protection est limité par un mécanisme autobloquant. Lorsque le stylo à insuline est mis en rotation dans le support d'aiguille, le mécanisme autobloquant s'ouvre automatiquement, et la protection se déplace librement vers le haut et vers le bas pour permettre l'injection normale d'insuline.
