Title (EN) MULTIFUNCTIONAL INDWELLING NEEDLE
(FR) AIGUILLE MULTIFONCTIONNELLE À DEMEURE
(ZH) 一种多功能留置针
Abstract:
(EN) A multifunctional indwelling needle, comprising a sleeve assembly (1) and a needle assembly (2), as well as an anti-reflux valve (14), an anti-stab safety device and a needleless positive pressure connector (5). The anti-reflux valve (14) is arranged in a middle cavity of a sleeve seat (11) and in the axial direction thereof, and at the front end of a flexible tube (3) communicated with said sleeve seat (11). The anti-stab safety device is arranged on a needle seat (22), and the needleless positive pressure device (5) is arranged on an external connector (4). The anti-stab safety device and the needleless positive pressure device (5) are both springless type devices. The multifunctional indwelling needle prevents blood overflow and resultant contamination, and avoids medical personnel being stabbed when extracting the needle. In addition, the springless structure avoids the rusting problems of springed structures, is safer and more hygienic, and ensures work stability and reliability.
(FR) L'invention concerne une aiguille multifonctionnelle à demeure, comprenant un ensemble manchon (1) et un ensemble aiguille (2) ainsi qu'une soupape antireflux (14), un dispositif de sécurité antiperforation et un raccord à pression positive sans aiguille (5). La soupape antireflux (14) est disposée dans une cavité centrale d'un siège (11) de manchon et dans la direction axiale correspondante et en communication, à l'extrémité frontale d'un tube flexible (3), avec ledit siège (11) de manchon. Le dispositif de sécurité antiperforation est disposé sur un siège (22) d'aiguille et le dispositif à pression positive sans aiguille (5) est disposé sur un raccord externe (4). Le dispositif de sécurité antiperforation et le dispositif à pression positive sans aiguille (5) sont tous les deux des dispositifs de type sans ressort. L'aiguille multifonctionnelle à demeure empêche le débordement du sang et la contamination qui en résulte et évite que le personnel médical ne se pique lors de l'extraction de l'aiguille. De plus, la structure sans ressort évite les problèmes de rouille des structures à ressort, est plus sûr et plus hygiénique et assure une stabilité et une fiabilité de travail.
(ZH) 一种多功能留置针,包括套管组件(1)和钢针组件(2),以及防逆流瓣膜(14)、防刺伤安全装置、无针正压接头(5)。所述防逆流瓣膜(14)设置在套管座(11)中腔,并在套管座(11)轴向上位于与套管座(11)连通的软管(3)前端。所述防刺伤安全装置设置在钢针座(22)上,所述无针正压接头(5)设置在外接接头(4)上。所述防刺伤安全装置为无弹簧式防刺伤安全装置,无针正压接头(5)为无弹簧式无针正压接头。上述多功能留置针能防止血液外溢造成污染,避免钢针拔出时刺伤医护人员。同时,无弹簧结构避免弹簧结构带来的锈蚀问题,更加安全卫生,确保留置针工作稳定可靠。
