Abstract

La présente invention concerne une seringue qui permet à un utilisateur d'effectuer un prélèvement sanguin et une succion ou injection de médicament en utilisant une seule main. La seringue de la présente invention comprend : un cylindre muni d'une aiguille à son extrémité avant, et d'un robinet qui s'étend perpendiculairement à partir de son extrémité arrière ; un plongeur muni d'un piston fixé à son extrémité avant, et d'une tête de piston fixée à son extrémité arrière, le piston étant inséré à l'intérieur du cylindre de manière à être en contact étroit avec une surface intérieure du cylindre et à effectuer un mouvement de va-et-vient dans l'état de contact étroit, le cylindre ayant une rainure formée sur sa surface extérieure dans la direction de sa longueur ; et une tige de manipulation qui s'étend dans la direction de la longueur du cylindre à partir de la tête du piston et qui est insérée à l'intérieur de la rainure de telle sorte que la surface supérieure de la tige de manipulation puisse être exposée à l'extérieur, la tige de manipulation ayant une partie de retenue de doigt formée sur la surface supérieure exposée de la tige de manipulation de telle sorte que le doigt de l'utilisateur ne glisse pas. La partie de retenue de doigt consiste en une pluralité de protubérances anti-glissement formées sur la partie supérieure de la tige de manipulation dans la direction de la longueur de la tige de manipulation, ou consiste en des reliefs anti-glissement dentés ou ondulés formés sur la surface supérieure de la tige de manipulation ou d'une garniture anti-glissement en matériau de caoutchouc ou de silicone et attachée à la surface supérieure de la tige de manipulation.
