膀胱造瘘管cystostomy tube

技术领域technical field

本实用新型涉及医疗器材领域，特别是涉及膀胱造瘘管。The utility model relates to the field of medical equipment, in particular to a bladder fistula tube.

背景技术Background technique

在泌尿外科的实际临床工作中，各种原因导致的膀胱永久造瘘情况非常常见。目前，对于膀胱造瘘，一般都使用专用的膀胱造瘘管。现有技术中的膀胱造瘘管，一般包括造瘘管，在造瘘管上设置一水囊，所述造瘘管的管头设有进尿口，造瘘管的尾端设有出尿口和充水口，在造瘘管上还会设置一个挡片或者固定片用以将造瘘管固定。使用时，将造瘘管的管头伸入膀胱合适位置，对水囊进行充水，轻拉造瘘管，使得水囊与膀胱内壁贴合，然后用挡片或者固定片贴在身体表面加以固定，一般采用缠绕医用胶带进行固定。In the actual clinical work of urology, permanent bladder fistula caused by various reasons is very common. Currently, for cystostomy, a dedicated cystostomy tube is generally used. The bladder fistula tube in the prior art generally includes a fistula tube, a water bladder is arranged on the fistula tube, the tube head of the fistula tube is provided with a urine inlet, and the tail end of the fistula tube is provided with a urine outlet and a water filling port, A blocking piece or a fixing piece is also arranged on the fistula tube to fix the fistula tube. When in use, insert the tube head of the fistula tube into the proper position of the bladder, fill the water bag with water, gently pull the fistula tube to make the water bag fit the inner wall of the bladder, and then stick it on the body surface with a baffle or a fixing sheet to fix it. Generally, it is fixed by wrapping medical tape.

但是，现有的膀胱造瘘管还存在以下问题：1、漏尿：造瘘管和腹壁瘘口之间不能完全封闭，尿液从造瘘管和造瘘口之间的缝隙流出，使患者全是尿骚味，影响生活质量和环境。不仅如此，尿液会产生细菌，导致造瘘口感染，更甚者细菌会通过造瘘管进入膀胱，一起泌尿系统感染，进而继发结石、肾盂肾炎等，危及患者生命。2、引流不完全，腹壁的膀胱造瘘管由于重力原因无法完全将尿液从膀胱内引出，每次只是将膀胱内部分尿液引出，膀胱内残余尿液，长时间会引起感染及膀胱结石。3、造瘘管无法弯曲，造瘘口在下腹部正中位置，现在的造瘘管就是尿管，无法弯曲，影响穿衣及生活质量。4、压力不可控：现在的膀胱造瘘管压力不可控，如果造瘘管堵塞或者受压，膀胱内压力超过安全压力可以引起肾积水及上尿路功能损害。尤其对于神经源性膀胱患者，其感觉神经不敏感，容易引起上尿路损伤。However, the existing cystostomy tube still has the following problems: 1. Urine leakage: the gap between the fistula tube and the abdominal wall fistula cannot be completely closed, and urine flows out from the gap between the fistula tube and the fistula opening, so that the patient is full of urine Smell, affect the quality of life and the environment. Not only that, the urine will produce bacteria, leading to infection of the ostomy opening. What’s more, the bacteria will enter the bladder through the ostomy tube, together with urinary system infection, and then secondary stones, pyelonephritis, etc., endangering the patient’s life. 2. The drainage is incomplete. The cystostomy tube in the abdominal wall cannot completely drain the urine from the bladder due to gravity. Each time, only part of the urine is drawn out of the bladder. The residual urine in the bladder will cause infection and bladder stones for a long time. 3. The ostomy tube cannot be bent, and the ostomy opening is in the middle of the lower abdomen. The current ostomy tube is the urinary catheter, which cannot be bent, which affects dressing and quality of life. 4. Uncontrollable pressure: The current pressure of the cystostomy tube is uncontrollable. If the fistula tube is blocked or compressed, the pressure in the bladder exceeds the safe pressure, which can cause hydronephrosis and damage to the upper urinary tract function. Especially for patients with neurogenic bladder, their sensory nerves are not sensitive, which can easily cause upper urinary tract injury.

The sealingassembly 23 in this embodiment is an elastic sealing ring (not shown in the figure), and the middle of the elastic sealing ring is provided with a A through hole through which the elastic sealing ring is in interference fit with the outer wall of theconduit 1 . The elastic sealing ring has elasticity, and the interference fit between the middle through hole and thecatheter 1 can play the role of pressing and closing thecatheter 1, and can effectively place urine to seep out.

为使得导管1可以弯曲，本实施例中，不再将挡片24上设置条形凹槽241，而是在导管1的外壁上设置一段便于弯曲的褶皱部(图中未示出)。该褶皱部类似于吸管上的褶皱，可以弯曲定型。褶皱部的设置根据人体膀胱7距离腹部皮肤表面进行合理设置。将造瘘管放置到膀胱7内，使水囊3充盈，固定好造瘘管，贴合上防渗漏组件2后，褶皱部紧挨挡片24即可，或者部分伸进防渗漏组件2的中心通孔中也可以实现弯曲定型。In order to make thecatheter 1 bendable, in this embodiment, the strip-shapedgroove 241 is no longer provided on thebaffle 24, but a folded portion (not shown in the figure) that is convenient for bending is provided on the outer wall of thecatheter 1. The pleats are similar to the pleats on a straw and can be bent to shape. The setting of the folded portion is reasonably set according to the distance between thehuman bladder 7 and the surface of the abdominal skin. The ostomy tube is placed in thebladder 7, thewater bladder 3 is filled, the ostomy tube is fixed, and after theanti-leakage assembly 2 is attached, the folded part is close to thebaffle 24, or a part of the ostomy tube is inserted into theanti-leakage assembly 2. Bend shaping is also possible in the central through hole.

以上所述实施例仅表达了本实用新型的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。The above-mentioned embodiments only represent several embodiments of the present utility model, and the descriptions thereof are specific and detailed, but should not be construed as a limitation on the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, some modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
