A new type of minimally invasive negative pressure drainage device consists of negative pressure drainage tube and negative pressure drainage device. The end of negative pressure drainage tube is connected with the inlet of negative pressure drainage device. The rear end face of the negative pressure drainage device is provided with a positioning piece. The positioning piece is connected with the rear end face of the tube body of the negative pressure drainage device. The negative pressure drainage device is provided with a syringe needle bolt. This invention has the advantages of precise manipulation, full negative pressure drainage and precise closure of the invalid cavity, which can effectively promote the circumfluence of the vein and promote the healing of the incision; it has little damage to the surrounding tissue, especially the fragile tissues such as blood vessels and nerves; therefore, it is safe, economical and effective. The convenient and negative pressure can be controlled by itself and the amount of attraction is great.
【技术实现步骤摘要】
一种新型微创负压引流器
本专利技术涉及医疗器械
,尤其是涉及一种新型微创负压引流器。
技术介绍
病人在外科手术后伤口渗出物需要引流,引流的目的是将手术中人体组织间或体腔中积聚的脓液、血液等导引至体外,防止术后感染与影响伤口愈合。现有的引流器在使用过程中容易造成引流管堵塞,从而影响引流效果或者需要反复在病人体内插接引流器增加病人手术痛苦。负压引流器主要用于对胸腔、腹腔患者穿刺手术后的引流,多功能胸腹穿刺负压引流器,由三通管、引流管和负压引流容器构成,由于该专利的负压引流容器为单纯的皱褶体构造,因此在使用时会暴露出以下技术问题:当将负压引流容器内的空气驱出处于收瘪状态后,即处于负压状态后往往存在舒张困难之虞。此外,由于该专利的负压引流器上的进液口及排液孔被分别设置在上表面及下表面,更确切地讲,因排液孔位于负压引流器的下表面,因此存在泄漏的风险。
技术实现思路
为克服上述问题,本专利技术采用如下技术方案:一种新型微创负压引流器,包括负压引流管和负压引流器组成,负压引流管末端经插接头与负压引流器进液口连接,负压引流器的管体后端面设有定位片,定位片与负压引流器的管体后端面 ...
