技术领域technical field
本实用新型属于医疗用品技术领域，具体涉及一种膀胱腔内术后防堵塞导尿管。The utility model belongs to the technical field of medical supplies, in particular to an anti-clogging urinary catheter in the bladder cavity after operation.
背景技术Background technique
目前，临床上前列腺增生，膀胱、尿道结石，前列腺癌，膀胱、尿道肿瘤等疾病术后，一般均需留置导尿管。由于术后创面出血，常常形成血块造成传统导尿管堵塞。一旦导尿管堵塞，发生尿潴留，病人将十分痛苦。传统解决方法是膀胱冲洗，甚至需要重新插管，不仅增加病人的痛苦和感染的风险，而且堵塞很容易反复发生，增加医务工作者的工作量。At present, clinically, indwelling urinary catheters are generally required after surgery for benign prostatic hyperplasia, bladder and urethral calculi, prostate cancer, bladder and urethral tumors and other diseases. Due to postoperative wound bleeding, blood clots are often formed causing blockage of traditional catheters. Once the catheter is blocked and urinary retention occurs, the patient will be very miserable. The traditional solution is to flush the bladder and even require re-intubation, which not only increases the pain of the patient and the risk of infection, but also the blockage is likely to occur repeatedly, increasing the workload of medical workers.
