Abstract

La présente invention se rapporte à une aiguille de bouteille en résine synthétique permettant d'effectuer facilement une centèse par réduction de la résistance à la poussée et accroissement du flux pour une transfusion de solution et une transfusion sanguine. Dans cette aiguille de bouteille, une face coupante constituée d'un grand nombre de faces est façonnée de manière pointue au niveau de la pointe aiguille d'une partie tube de l'aiguille pour réduire la résistance à la poussée, et la partie intermédiaire ou l'extrémité de la face coupante est ouverte de manière à constituer un trou de collecte de la solution et à rendre sûre une zone d'ouverture. L'aiguille de bouteille se caractérise en ce que la pointe aiguille est formée d'une matière solide et en ce que quatre faces coupantes sont formées au niveau de la pointe aiguille de la même manière que dans une aiguille d'injection, ladite pointe aiguille présentant une forme triangulaire formant une pyramide trigonale et le trou de collecte de la solution étant formé au niveau de la partie intermédiaire de la face coupante, l'extrémité de la pointe aiguille étant ouverte pour former le trou de collecte de la solution et la pointe aiguille ayant une partie d'extrémité plate et présentant une section transversale de forme semi-circulaire, ou bien des parties rainurées étant formées, selon une forme ondulée, dans les faces coupantes sur les côtés des deux faces coupantes opposées l'une à l'autre.
