本实用新型的工作原理：尿液从肾盂产生后通过圆环部2上的通孔3进入支架管体1，尿液往下流入膀胱并会产生一定的压力，在支架管体1的连接部通过尿液产生的压力一路将硅胶防逆阀5开启流入膀胱。当尿液充盈满膀胱使硅胶防逆阀5内外压力相同或外压力大于内压力时，此压力作用于硅胶防逆阀5的外表面，使该阀上的切口6向内变形，由于管内使其变形的空间太小且切口有向外的弹力，硅胶防逆阀5上的切口6仍然会保持密闭状态，有效阻止了膀胱尿液逆流至肾盂，因肾脏在不断的产生尿液，当肾盂内压力大于膀胱内压力后，硅胶防逆阀5会自动开启；当尿液充盈满膀胱，膀胱压力大于肾脏內压力时，开口型扁平球囊3会在外压力作用或球囊内自然张力下自然封闭开口，有效阻止了膀胱尿液逆流至肾盂，因肾脏在不断的产生尿液，当肾盂内压力大于膀胱内压力后，尿液自然流出球囊7；同时，临床医生可根据患者输尿管长短合理选定密封塞9的位置，对膀胱端输尿管口进行有效的封堵，防止尿液逆流于肾脏。The working principle of the utility model: after the urine is produced from the renal pelvis, it enters the stent tube body 1 through the through hole 3 on the ring part 2, and the urine flows down into the bladder and generates a certain pressure. The pressure generated by the urine opens the silicone anti-reverse valve 5 and flows into the bladder. When the bladder is filled with urine so that the internal and external pressure of the silicone anti-reverse valve 5 is the same or the external pressure is greater than the internal pressure, this pressure acts on the outer surface of the silicone anti-reverse valve 5, causing the cutout 6 on the valve to deform inward. The deformation space is too small and the incision has outward elasticity. The incision 6 on the silicone anti-reverse valve 5 will still remain airtight, which effectively prevents bladder urine from flowing back to the renal pelvis. Because the kidneys are constantly producing urine, when the renal pelvis After the internal pressure is greater than the internal pressure of the bladder, the silicone anti-reverse valve 5 will automatically open; when the bladder is filled with urine and the bladder pressure is greater than the internal pressure of the kidney, the open-type flat balloon 3 will naturally open under the external pressure or the natural tension inside the balloon. The opening is closed to effectively prevent bladder urine from flowing back to the renal pelvis. Because the kidneys are constantly producing urine, when the pressure in the renal pelvis is greater than the pressure in the bladder, the urine will naturally flow out of the balloon 7; at the same time, the clinician can adjust the length of the ureter according to the length of the patient. Select the position of the sealing plug 9 to effectively block the ureteral orifice at the bladder end to prevent urine from flowing backward into the kidney.
本实用新型运用临床介入治疗处理上述疾病，其机理是作用在输尿管壁上，产生持续柔和的径向扩张力，使狭窄部位恢复通畅并与输尿管内壁紧贴，使粘模嵌入，促进上皮细胞覆盖，防止结石产生，更重要的是其有效阻止了尿液从膀胱逆流入肾脏，减少了患者上述的痛苦，防止二次上尿路梗阻和扩张积水，使继发尿路感染以及结石复发机率大大降低The utility model uses clinical interventional therapy to deal with the above-mentioned diseases, and its mechanism is to act on the ureter wall to generate a continuous and soft radial expansion force, so that the narrow part can be restored to smooth and close to the inner wall of the ureter, so that the sticky mold can be embedded to promote epithelial cell coverage , to prevent stones, and more importantly, it effectively prevents urine from backflowing from the bladder into the kidneys, reducing the above-mentioned pains of patients, preventing secondary upper urinary tract obstruction and dilated water, and reducing the chance of secondary urinary tract infection and recurrence of stones Greatly reduced
