Abstract

L’invention concerne un porteur d’aiguille munie d’ailettes utilisé lors d’une transfusion, d’une perfusion de sang, d’un prélèvement sanguin, etc. lequel consiste en une partie porteuse (3) pour une aiguille munie d’ailettes (6) formée horizontalement dans la partie d'attachement (2) servant à attacher le porteur à un poteau de support (71) d'un panneau d'instillation (7), la partie porteuse (3) comprenant une paire de pinces élastiques (31,31) tenant les deux côtés d'une lame (65), dans un état où les lames (65,65) de l'aiguille munie d’ailettes (6) sont soulevées, et en un support (4) pour supporter la périphérie externe (67) de la lame (65) de l'aiguille munie d’ailettes (6) disposé en dessous. Du fait de la constitution décrite ci-dessus, l'aiguille munie d’ailettes (6) peut être aisément et facilement retirée et tenue avec une main pendant que l’on retire un capuchon (66) d'une aiguille tubulaire (61) présente à la pointe de l'aiguille munie d’ailettes (6). Ainsi, un traitement pour nettoyer le corps d'un patient ou arrêter un saignement peut être réalisé sans souci. De plus, un traitement médical peut être apporté sans risque de contamination d'un médecin, d’une infirmière et d’un patient avec l'aiguille tubulaire (61) dont le capuchon (66) a été retiré.
