Summary: | The present invention can prevent a drug that has been discharged during air removal and that is retained at a skin-contacting section from attaching to the skin of a user. The present invention is provided with: a needle tube (5) having a needle tip that punctures skin; a needle hub (6); and an absorption section (26) that absorbs the drug. The needle hub (6) has: a holding section (first member (11)) that holds the needle tube; an insertion section (31) to which the discharge section (52) of a syringe is inserted; and a flange-shaped skin-contacting section (25) that is disposed in a manner so as to cover the periphery of the needle tube (5) and that contacts and/or faces the skin when the needle tube (5) punctures a living body. Also, the absorption section (26) is provided to the skin-contacting section (25) of the needle hub (6).
Cette invention permet à un utilisateur d'éviter qu'un médicament, libéré lors d'un processus d'élimination d'air et qui stagne au niveau d'une zone de contact cutané, adhère à la peau. Le dispositif selon l'invention est équipé : d'un tube d'aiguille (5) comportant une pointe d'aiguille perforant la peau ; d'un raccord d'aiguille (6) ; et d'une zone d'absorption (26) qui absorbe le médicament. Le raccord d'aiguille (6) comporte : une zone de retenue (premier élément (11)) retenant le tube d'aiguille ; une zone d'insertion (31) dans laquelle est introduite la zone de libération (52) d'une seringue ; et une zone de contact cutané en forme de collerette (25) qui est conçue pour recouvrir la périphérie du tube d'aiguille (5), et qui touche et/ou fait face à la peau lorsque le tube d'aiguille (5) perfore le corps vivant. La zone d'absorption (26) est située au niveau de la zone de contact cutané (25) du raccord d'aiguille (6). |
