Description

测压无创防堵导尿装置 Pressure attempts to prevent non-invasive catheterization device

技术领域 FIELD

[0001] 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。 [0001] The present invention relates to the field of medical devices, particularly to a non-invasive pressure measuring device attempts to prevent catheterization.

背景技术 Background technique

[0002] 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。 [0002] Urology hematuria is a common symptom of a patient, such as urinary tract stones, tumors, trauma and the like, when large amount of bleeding, high concentrations of hematuria, urinary retention and easy formation of blood clots in the bladder left urinary tract obstruction, leading to acute renal failure and life-threatening, and often require emergency surgery to clear a blood clot. 因此临床一旦出现大量血尿,常需急诊积极处理。 Therefore, once a large number of clinical hematuria, often need to actively deal with the emergency.

[0003]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:(I)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; [0003] Although there are several anti-clogging of the catheter medical products, but not easy to implement, the effect is not exact; The current clinical use of triple lumen catheter for irrigation and drainage, with physiological saline injected from the water inlet pipe after dilution bladder urine, drained through the outlet conduit, to a certain extent to avoid formation of blood clots in the bladder, but there are still many problems in clinical use: (I) triple-lumen catheter drainage of the main driving force from pressure within the bladder , the pressure is relatively small, and limited drainage tube lumen, when the bladder memory clot blocking the lumen easily, repeated use of syringe flushing medical need, medical personnel may need a few minutes rinse, medical staff in greatly increased the amount of waste of medical resources; (2) to increase the drainage suction drainage to enhance the effect of pressure, but clinical use drainage tube soft texture, often attached to negative pressure so that the wall is collapsed, can not be achieved;

[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。 [3] Current clinical use of catheter products can not show the bladder pressure, and for some patients with coma patient can not perceive bloating, which require close observation of medical staff on a regular basis and even repeated B-ultrasound to understand the effect of draining the bladder, also increased medical staff workload, waste of medical resources; (4) clinical Some patients need long-term indwelling catheter, but the use of catheters to prevent infection often need to be replaced regularly, will increase patient suffering, waste of medical resources.

[0004] 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。 [0004] Therefore, to develop a catheterization good effect, and can be observed in real time pressure information within the bladder, direct knowledge of the effect of drainage, urine drainage system for small trauma patients required urgent clinical.
