发明内容Contents of the invention

本发明的目的是提供一种无需外接集尿袋、通过患者定时自行插管排尿的一种新型膀胱造瘘管。The purpose of the present invention is to provide a new type of cystostomy tube that does not need an external urine collection bag and allows patients to urinate through the catheter at regular intervals.

本发明通过改变膀胱造瘘管持续引流尿液的传统设计，提供一种无需外接集尿袋、通过患者定时自行插管排尿、防止尿液外渗的膀胱造瘘管。The present invention provides a cystostomy tube that does not need an external urine collection bag by changing the traditional design of the bladder tube for continuous drainage of urine, allows the patient to urinate through the tube at regular intervals, and prevents urine from leaking out.

本发明提供一种无需集尿袋的膀胱造瘘管，包括管壁、固定板、管壁外周的水囊、连接水囊的注水阀及管腔内的活塞瓣，其中管壁与固定板连接，注水阀位于固定板上，水囊一端通过固定板与管壁内的管腔与注水阀相通，管腔内的活塞瓣连于管壁，活塞瓣具有3-4个活塞瓣叶。The invention provides a cystostomy tube without a urine collection bag, which comprises a tube wall, a fixing plate, a water bag around the tube wall, a water injection valve connected to the water bag, and a piston valve in the tube cavity, wherein the tube wall is connected to the fixing plate, The water injection valve is located on the fixed plate, and one end of the water bag communicates with the water injection valve through the fixed plate and the lumen in the tube wall. The piston flap in the tube cavity is connected to the tube wall, and the piston lobe has 3-4 piston flaps.

上述的固定板与管壁连为一体，固定板宽为2cm，厚1cm，用于膀胱造瘘管置入后抵住腹壁，起外固定的作用，防止膀胱造瘘管向内滑落。The above-mentioned fixing plate is integrated with the tube wall. The fixing plate has a width of 2 cm and a thickness of 1 cm. It is used to support the abdominal wall after the cystostomy tube is placed, and acts as an external fixation to prevent the bladder tube from slipping inward.

上述的水囊围绕着管壁，远端距管壁内口1cm，近端通过固定板与管壁内的管道与注水阀相通。由于使用的水囊长度大于瘘管的长度，所以当水囊内注入生理盐水后，瘘管内水囊膨胀、与瘘管壁紧密贴合，防止尿液外渗；膀胱内的水囊则自然膨胀，起内固定的作用，防止造瘘管向外滑出。The above-mentioned water bag surrounds the pipe wall, the far end is 1 cm away from the inner opening of the pipe wall, and the proximal end communicates with the pipeline in the pipe wall and the water injection valve through the fixing plate. Since the length of the water bladder used is longer than the length of the fistula, when physiological saline is injected into the water bladder, the water bladder in the fistula expands and fits closely with the wall of the fistula to prevent urine from leaking out; Internal fixation prevents the ostomy tube from slipping out.

上述的注水阀位于固定板上，可以与固定板连为一体，通过固定板和管壁内的管道与水囊相通，可用注射器向内注水，当向注水阀内注射生理盐水时，盐水即流向水囊，使水囊充盈扩张并贴紧造瘘管内壁，而伸入膀胱内部分水囊其扩张程度会大于造瘘管内水囊，从而起到固定作用并防止造瘘管向外脱落。The above-mentioned water injection valve is located on the fixed plate and can be connected with the fixed plate as a whole. It communicates with the water bag through the pipeline in the fixed plate and the pipe wall, and a syringe can be used to inject water inward. When physiological saline is injected into the water injection valve, the saline will flow to The water bladder makes the water bladder fill and expand and stick to the inner wall of the ostomy tube, and the part of the water bladder that extends into the bladder will expand more than the water bladder in the ostomy tube, so as to play a fixed role and prevent the ostomy tube from falling out.

上述管腔内的活塞瓣连于管壁，距管壁内口1cm，由3-4个活塞瓣叶组成。活塞瓣叶可向内张开，利于插管排尿；而当膀胱内尿液作用于活塞瓣叶时，活塞瓣叶间相互靠紧，阻塞管腔，防止尿液外流。The piston valve in the above-mentioned tube cavity is connected to the tube wall, 1 cm away from the inner opening of the tube wall, and consists of 3-4 piston valve leaves. The valve leaflets of the piston can be opened inward, which is beneficial for intubation and urination; and when the urine in the bladder acts on the leaflets of the piston, the leaflets of the piston are close to each other, blocking the lumen and preventing the outflow of urine.

本发明提供给膀胱造瘘病人瘘管形成之后(膀胱造瘘术1个月后)使用。The present invention is provided for use after the formation of fistula in patients with cystostomy (one month after cystostomy).

本发明可设计不同长度、直径的造瘘管，适合不同瘘管大小、不同体型病人使用。The invention can design fistula tubes with different lengths and diameters, and is suitable for patients with different fistula sizes and body shapes.

本发明适合膀胱造瘘后需长期置管的病人，在其瘘管形成之后使用。其优点为：1、无腹壁外的导尿管和集尿袋，极大地方便了病人的日常生活，减轻病人的自卑心理，使其能更好地融入社会；2、造瘘管固定牢固，不会移动，尿液不外渗；3、减少了尿液外渗、尿管外露带来的逆行感染风险，减轻了平时的护理工作；4、能使病人自行控制膀胱定时排尿，利于保护膀胱功能，预防膀胱萎缩等并发症。The invention is suitable for patients who need long-term catheterization after cystostomy, and is used after the fistula is formed. Its advantages are: 1. There is no urinary catheter and urine collection bag outside the abdominal wall, which greatly facilitates the patient's daily life, reduces the patient's inferiority complex, and enables him to better integrate into society; 3. Reduce the risk of retrograde infection caused by urine extravasation and urinary catheter exposure, and reduce the usual nursing work; 4. Enable patients to control their bladder to urinate regularly, which is conducive to protecting bladder function , Prevent complications such as bladder atrophy.

固定板5与管壁2连为一体，固定板5宽为2cm，厚1cm，用于造瘘管置入后抵住腹壁，起外固定的作用，防止造瘘管向内滑落。Thefixed plate 5 is integrated with thetube wall 2. Thefixed plate 5 is 2 cm wide and 1 cm thick. It is used to hold the abdominal wall after the ostomy tube is inserted, and plays the role of external fixation to prevent the ostomy tube from slipping inward.

水囊4围绕管壁2，远端7距管壁内口1cm，近端8通过固定板与管壁内的管道10与注水阀6相通。由于使用的水囊长度大于瘘管的长度，所以当水囊内注入生理盐水后，瘘管内水囊膨胀、与瘘管壁紧密贴合，防止尿液外渗；膀胱12内的水囊则自然膨胀，起内固定的作用，防止造瘘管向外滑出，如图2所示。Thewater bag 4 surrounds thepipe wall 2, the far end 7 is 1 cm away from the inner mouth of the pipe wall, and the proximal end 8 communicates with thewater injection valve 6 through the fixed plate and thepipeline 10 in the pipe wall. Since the length of the water bladder used is greater than the length of the fistula, when physiological saline is injected into the water bladder, the water bladder in the fistula expands and fits closely with the wall of the fistula to prevent urine from leaking out; the water bladder in the bladder 12 naturally expands, It plays the role of internal fixation to prevent the ostomy tube from sliding out, as shown in Figure 2.

注水阀6位于固定板5上，注水阀外部由硬质塑料制成，内部的注水阀芯9由橡胶制成，注水阀与固定板连为一体，通过固定板和管壁内的管道10与水囊相通，可用注射器通过注水阀芯9向内注水，当向注水阀内注射生理盐水时，盐水即流向水囊，使水囊充盈扩张并贴紧造瘘管内壁，而伸入膀胱内部分水囊其扩张程度会大于造瘘管内水囊，从而起到固定作用并防止造瘘管向外脱落。Thewater injection valve 6 is located on thefixed plate 5. The outside of the water injection valve is made of hard plastic, and the inner waterinjection valve core 9 is made of rubber. The water bladder is connected, and a syringe can be used to inject water inward through the waterinjection valve core 9. When physiological saline is injected into the water injection valve, the saline will flow to the water bladder, causing the water bladder to fill and expand and adhere to the inner wall of the fistula tube, and extend into the bladder to part the water The dilatation of the sac will be larger than that of the water sac in the ostomy tube, so as to fix it and prevent the ostomy tube from falling out.

管腔内的活塞瓣连于管壁，距管壁内口1cm，瓣叶可向内张开，利于插管排尿；而当膀胱内尿液作用于瓣叶时，瓣叶间相互靠紧，阻塞管腔，防止尿液外流。The piston valve in the lumen is connected to the tube wall, 1cm away from the inner opening of the tube wall, and the valve leaflets can be opened inward, which is convenient for intubation and urination; when the urine in the bladder acts on the valve leaflets, the leaflets are close to each other, Block the lumen to prevent the outflow of urine.
