Abstract

La présente invention concerne un système de seringue permettant de prévenir des erreurs de médication, le système de seringue, permettant de prévenir des erreurs de médication, empêchant un fluide à injecter d'être incorrectement injecté à un patient en ayant en outre une propriété d'accouplement mécanique ou magnétique particulière dans une partie de connexion qui relie l'un à l'autre un cathéter vasculaire, qui injecte le fluide à injecter dans un vaisseau sanguin, et un récipient de fluide à injecter, qui contient le fluide à injecter. En empêchant l'administration incorrecte d'un médicament à un patient même lorsqu'un médecin est incapable d'accorder une attention appropriée, la sécurité de l'administration du médicament par injection peut être améliorée. En outre, au moyen d'un procédé de codage, la présente invention peut être dotée d'une variété de structures d'accouplement différenciées et uniques pour chaque médicament et chaque patient.
