摘要：
A needle tube puncture assembly for a safe indwelling needle is a puncture assembly for a safe indwelling needle, capable of limiting a position by means of a pull rope, and comprises a needle tip stop member (2), a needle tip shielding member (3), an operation handle (4), a needle tube (6), and a needle seat (7). The needle tip shielding member (3) and a duct seat are connected in a disengageable manner. After a needle is withdrawn, the needle tip shielding member (3) is separated from the duct seat. Key points of the structure of the puncture assembly are as follows: the puncture assembly also comprises a pull rope limiting device comprising a pull rope (5.2), one end of the pull rope (5.2) is connected to the needle seat (7), the other end of the pull rope (5.2) is connected to the needle tip shielding member (3), the pull rope (5.2) is pressed into a cylindrical and annular cavity between a handle cavity and the needle tip shielding member (3), and the stretching length of the pull rope (5.2) is greater than a stroke by which the needle tip retreats to the back end of the needle tip stop member (2). Compared with the prior art, the needle tube puncture assembly for an indwelling needle has the following advantages: the structure is simple, and the position limitation is more reliable and effective.La présente invention concerne un ensemble perforation de tube d'aiguille pour une aiguille à demeure sûre qui constitue un ensemble perforation pour une aiguille à demeure sûre, susceptible de retenir une position à l'aide d'une corde de traction, et qui comprend un élément d'arrêt de pointe d'aiguille (2), un élément de protection de pointe d'aiguille (3), une poignée d'actionnement (4), un tube d'aiguille (6), et un siège d'aiguille (7). L'élément de protection de pointe d'aiguille (3) et un siège de conduit sont reliés de manière à pouvoir se désolidariser. Après le retrait d'une aiguille, l'élément de protection de pointe d'aiguille (3) est séparé du siège de cond
