技术领域Technical Field
本发明涉及一种导尿管，特别是公开一种滤网支架型导尿管。The invention relates to a urinary catheter, in particular to a filter bracket type urinary catheter.
背景技术Background technique
传统的普通橡胶导尿管无论型号大小前端只有两个引流尿液的通孔，对于长期留置导尿管的患者一旦有颗粒沉淀或大块组织样物质堵塞很容易造成导尿管堵管，而解决堵管的主要方法就是重新更换导尿管。期间会造成病人痛苦、增加尿路感染的风险、同时也增加了医护工作的工作量。Conventional common rubber catheters, regardless of size, only have two through holes at the front end for drainage of urine. For patients with long-term indwelling catheters, once particles or large tissue-like substances are blocked, it is easy to cause catheter blockage. The main way to solve the blockage is to replace the catheter. This will cause pain to the patient, increase the risk of urinary tract infection, and also increase the workload of medical care.
