Description
技术领域technical field
本实用新型涉及一种医疗器械，尤其涉及一种防渗导尿管。The utility model relates to a medical device, in particular to an anti-seepage catheter.
背景技术Background technique
临床最早使用的导尿管为单腔导尿管，即一条一定长度的单腔软质橡胶管，该种导尿管的弊端是使用时必须借助胶带等进行外固定，但固定不牢固，非常容易脱落，由此给患者增加了重复导尿的痛苦，由此还可能增加感染的机会，该种尿管基本上已经淘汰不用。The earliest clinically used urinary catheter is a single-lumen catheter, that is, a single-lumen soft rubber tube of a certain length. It is easy to fall off, thus increasing the pain of repeated catheterization to the patient, which may also increase the chance of infection, and this kind of urinary catheter has basically been eliminated.
目前临床常用的导尿管为双腔导尿管，其结构为：一条一定长度的双腔乳胶管，其中一腔的一端与膀胱直接相通，另一端外接引流管和集尿袋；另一腔的一端连接球囊(位于膀胱内)，另一端连接有球囊注入口(位于尿道口外)，该种导尿管的插管方法与单腔导尿管相同，区别在于：插管成功后通过球囊注入口注入一定量的液体或气体，使球囊充盈从而固定导尿管，不需要胶带等外固定，该种导尿管固定牢固，不容易脱落。At present, the clinical commonly used catheter is a double-lumen catheter, and its structure is: a double-lumen latex tube of a certain length, one end of one lumen is directly connected with the bladder, and the other end is connected with a drainage tube and a urine collection bag; One end of the catheter is connected to the balloon (located in the bladder), and the other end is connected to the balloon injection port (located outside the urethral opening). The catheterization method of this type of catheter is the same as that of the single-lumen catheter. Inject a certain amount of liquid or gas through the injection port of the balloon to fill the balloon and fix the catheter without external fixation such as tape. This kind of catheter is firmly fixed and not easy to fall off.
近年有人设计了一种三腔导尿管，其结构与双腔导尿管类似，只是将双腔改为三腔，多出一条腔，该腔的一端与膀胱相通，另一端通往膀胱外连接控制端口，单用于膀胱冲洗，该种导尿管主要用于膀胱出血时进行膀胱冲洗，所以又称为三腔止血导尿管。In recent years, someone has designed a three-chamber urinary catheter. Its structure is similar to that of a double-chamber catheter, except that the double-chamber is changed to three-chamber, and there is an extra chamber. One end of the chamber communicates with the bladder, and the other end leads to the outside of the bladder. Connected to the control port, it is only used for bladder irrigation. This kind of catheter is mainly used for bladder irrigation when the bladder is bleeding, so it is also called a three-chamber hemostatic catheter.
临床使用中发现，上述双腔、三腔导尿管都存在下述缺点：①对于尿道松弛的患者，尤其女性患者来说，容易出现渗尿，即尿液通过导尿管与尿道的间隙流到体外。②长时间留置导尿可能导致尿道及膀胱括约肌张力异常，导致拔除导尿管时尿失禁或排尿困难。In clinical use, it is found that the above-mentioned double-lumen and triple-lumen catheters all have the following disadvantages: ① For patients with loose urethra, especially female patients, it is easy to have urine leakage, that is, urine flows through the gap between the catheter and the urethra. out of the body. ②Long-term indwelling catheterization may lead to abnormal tone of urethral and bladder sphincters, resulting in urinary incontinence or dysuria when the catheter is removed.
