Description
技术领域 technical field
本发明涉及医疗器械技术领域,具体涉及一种测压无创防堵导尿装置。 The invention relates to the technical field of medical devices, in particular to a pressure measuring non-invasive anti-blocking urinary catheterization device.
背景技术 Background technique
血尿是泌尿外科患者的常见症状,如泌尿系结石、肿瘤、外伤等等,出血量大时,血尿浓度高,尿液易在膀胱内潴留形成血凝块阻塞尿路,导致急性肾衰竭危及生命,常需要急诊手术清除血块。因此临床一旦出现大量血尿,常需急诊积极处理。 Hematuria is a common symptom of urological patients, such as urinary stones, tumors, trauma, etc. When the amount of bleeding is large, the concentration of hematuria is high, and the urine tends to be retained in the bladder to form blood clots that block the urinary tract, leading to acute renal failure and life-threatening , often requiring emergency surgery to remove the clot. Therefore, once a large amount of hematuria occurs clinically, emergency treatment is often required.
目前虽然有一些防堵塞导尿管的医疗器械产品,但实现起来并不容易,效果亦不确切;如目前临床采用三腔导尿管进行冲洗引流,从进水管道用生理盐水注入膀胱后稀释尿液,通过流出管道引流出,在一定程度上能避免膀胱内血凝块形成,但临床使用上尚存在诸多问题:(1)三腔导尿管引流动力主要来源于膀胱内压力,压力相对小,且引流管的管腔有限,在膀胱内存在血凝块时极易堵塞管腔,需医护人员反复使用注射器冲洗,有时几分钟就需医务人员冲洗一次,大大增加医务人员工作量,浪费医疗资源;(2)负压吸引能增加引流压力增强引流效果,但目前临床使用引流管质地软,接负压时常使管壁瘪陷,不能实现;(3)目前临床使用的导尿管产品不能显示出膀胱内压力情况,而对于一些昏迷患者不能感知腹胀患者,常需医务人员定期密切观察甚至反复B超检查了解膀胱内引流效果,同样增加医务人员工作量,浪费医疗资源;(4)临床部分病人需长期留置导尿管,但目前使用导尿管为避免感染常需定期更换,无疑增加病人痛苦,浪费医疗资源。 Although there are some medical device products for anti-clogging urinary catheters, it is not easy to implement and the effect is not exact; for example, three-lumen urinary catheters are currently used in clinical practice for flushing and drainage, and normal saline is injected into the bladder from the water inlet pipe and then diluted Urine is drained through the outflow tube, which can avoid the formation of blood clots in the bladder to a certain extent, but there are still many problems in clinical use: (1) The drainage power of the three-lumen catheter mainly comes from the pressure in the bladder, and the pressure is relatively high. The drainage tube is small, and the lumen of the drainage tube is limited. When there is a blood clot in the bladder, it is easy to block the lumen. The medical staff needs to repeatedly use the syringe to flush, sometimes it takes only a few minutes for the medical staff to flush once, which greatly increases the workload of the medical staff and wastes Medical resources; (2) Negative pressure suction can increase the drainage pressure and enhance the drainage effect, but the current clinical use of drainage tubes is soft, and the tube wall is often collapsed when connected to negative pressure, which cannot be realized; (3) The current clinical use of urinary catheter products The pressure in the bladder cannot be displayed, and for some comatose patients who cannot perceive abdominal distension, medical staff often need to observe closely regularly or even repeat B-ultrasound examinations to understand the drainage effect in the bladder, which also increases the workload of medical staff and wastes medical resources; (4) Some clinical patients need long-term indwelling urinary catheters, but the current use of urinary catheters often requires regular replacement to avoid infection, which undoubtedly increases the suffering of patients and wastes medical resources.
因此,研发一种导尿效果好,且能实时观察到膀胱内的压力信息,直接了解引流效果,对病患创伤小的尿液引流装置成为临床迫切所需。 Therefore, it is urgent to develop a urine drainage device with good catheterization effect, real-time observation of bladder pressure information, direct understanding of drainage effect, and less trauma to patients.
