Abstract

Dispositif de sécurité pour aiguille à ailettes possédant un capuchon de protection (20) doté d'une section découpée (23) au travers de laquelle passe une section de base de sections d'ailettes superposées (32) et possédant une section de mâchoires (24) empêchant la chute des sections d'ailettes (32) introduites dans la section découpée (23) ; un corps de boîtier plat (10) pour recevoir et tenir les capuchons de protection (20) ; et une couche adhésive installée sur la surface inférieure du corps du boîtier (10). Une bande adhésive à double face à papier antiadhésif peut être utilisée comme couche adhésive. Le corps du boîtier (10) est fixé par la couche adhésive à l'endroit souhaité à côté d'un patient. Une fois l'injection ou la perfusion terminée, on retire l'aiguille à ailettes (31) de la partie injectée en tenant les sections à ailettes (32) et on introduit une aiguille (31) directement dans le capuchon de protection (20) puis on la retire du corps de boîtier (10) faisant que le capuchon de protection (20) recouvre l'aiguille (31). Le danger de piqûre de l'autre main par l'aiguille est donc éliminé, et l'étanchement du sang peut donc être effectué par l'autre main suite au retrait de l'aiguille à injection. Ce dispositif de sécurité permet donc d'introduire l'aiguille à ailettes de manière fiable dans le capuchon de protection avec la seule main tenant la section ailettes de l'aiguille à ailettes.
