The case involves a puncture drainage tube for preventing blockage, detachment and seepage of pleural and peritoneal effusion, including: the main body of the drainage tube, which includes the drainage section, transition section and outflow section arranged in turn; the flusher, which is an elastic cystic structure located outside the outflow section, is connected with the main body of the drainage tube; the casing, which is sleeved and fixed outside the transition section; the liner, which is sleeved in the transition section and the casing. A structure with a closed cavity is composed of a casing; a heparin gelatin slow-release film is arranged on the inner wall of the drainage section; a drainage bag interface is arranged at the free end end of the drainage section; the present invention reduces the operation flow and the risk of external infection during flushing; an anti-slip bag and an anti-detachment bag effectively reduce the occurrence of seepage and abscission, and reduce the occurrence of seepage and abscission by slowly releasing heparin. The occurrence of large particle condensate in the tube effectively prevents the occurrence of pipe blockage.

防堵防脱防渗的胸腹腔积液穿刺引流管
本专利技术属于医用器材领域,具体涉及一种防堵防脱防渗的胸腹腔积液穿刺引流管。
技术介绍
胸腹腔积液穿刺引流术因创口小、痛苦少、恢复快等优点,在外科处理、肿瘤姑息治疗等方面应用较为普遍,通常采用一种使用穿刺套管针和引流管相配合的方式。具体地,首先由穿刺套管针插入胸腹腔中以建立通道,从而植入引流管进行胸腹腔积液的引流,引出的胸腹腔积液由引流袋收集。当前的胸腹腔积液穿刺引流术所采用的引流管主要存在以下问题:1、易堵塞;由于患者的胸腹腔积液中常含有红细胞、浆膜腔上皮脱落细胞、粘蛋白等成分,容易发生凝结堵塞引流管,造成胸腹腔积液难以顺利排出,此时需反向冲洗引流管,加大了医护人员的工作量;2、冲洗困难,易感染;引流管发生堵塞时需反向冲洗引流管,工作人员需打开引流管的注射端注入冲洗液,此操作过程中可能会将外部致病菌微生物带入胸腹腔内,增加感染风险,使本来就虚弱的患者病情雪上加霜;3、易松脱;引流管壁较为光滑,插入后如固定不牢固会导致引流管滑脱,此时需重新插入,给患者造成不必要的痛苦;而固定通常采用医用胶带,一方面会对部分敏感皮肤患者造成刺激, ...
