Abstract

La présente invention concerne un dispositif de collecte de sang sans danger et commode, comprenant en outre un bouton d'entretien absent dans un dispositif de collecte de sang classique, comme indiqué dans le dessin annexé, un trou d'aiguille de phlébotomie étant en outre formé au niveau d'un étui de protection pour faciliter le remplacement d'une aiguille de phlébotomie, et un moyen d'installation comprenant une surface coupée pour fixer l'aiguille de phlébotomie étant en outre formé au niveau d'une partie de phlébotomie. La présente invention peut commander avec précision l'étui de protection par l'intermédiaire du bouton d'entretien, tout en distinguant visuellement la longueur projetée de l'aiguille de phlébotomie lorsque l'aiguille de phlébotomie fait saillie à partir de l'étui de protection, et permet ainsi une utilisation sans danger en fournissant la longueur projetée de l'aiguille de phlébotomie appropriée pour une épaisseur de peau, un âge et analogues d'un utilisateur. De plus, par l'intermédiaire du trou d'aiguille de phlébotomie, formé au niveau de l'étui de protection, et du moyen d'installation, fait d'un matériau élastique, comprenant une surface coupée formée au niveau de la partie de phlébotomie de façon à correspondre au trou d'aiguille de phlébotomie, il est possible de remplacer de façon commode une aiguille de phlébotomie par une nouvelle aiguille de phlébotomie en poussant simplement la nouvelle aiguille de phlébotomie sans la séparer de l'étui de protection.
