Translated fromChinese技术领域technical field
本实用新型涉及引流技术领域，尤其涉及一种尿道引流装置。The utility model relates to the technical field of drainage, in particular to a urethral drainage device.
背景技术Background technique
目前，前列腺、膀胱尿道疾病的患者需要留置尿管，由于术后一段时间内，创面会出血，血液进入尿管后，尿管空间小，造成尿管堵塞。一旦堵塞形成，尿液或冲洗液无法及时排出尿管，会使患者有着强烈疼痛感，传统的处理方法是通过逆向增压进行清除，但是该方法操作繁琐，并会对患者造成更大的伤害。所以医务人员也会采用取出尿管，进行疏通处理，但是多次更换时间成本过高，同时也会对患者造成伤害，甚至逆向感染。At present, patients with prostate and bladder urethral diseases need to indwell the urinary catheter, because the wound will bleed for a period of time after the operation, and after the blood enters the urinary catheter, the space of the urinary catheter is small, resulting in blockage of the urinary catheter. Once the blockage is formed, the urine or flushing fluid cannot be discharged from the urinary catheter in time, which will cause severe pain to the patient. The traditional treatment method is to remove it by reverse pressurization, but this method is cumbersome to operate and will cause greater harm to the patient. . Therefore, medical personnel will also take out the urinary catheter and dredge it, but the cost of multiple replacements is too high, and it will also cause harm to the patient, and even reverse infection.
中国专利CN207785562U公开了一种防止血块堵塞的导尿管，包括排尿管、密封圈、引尿管、倒刺和过滤网，所述排尿管的左侧连接有气压调节管，且排尿管的上方固定有连接套筒，所述密封圈位于连接套筒的内部，所述导尿管的下方连接有固定套圈，所述支撑杆通过下方安装的固定件与操作手环相连接，所述倒刺固定在支撑杆的外侧，且支撑杆的上方安装有清洁刷毛，所述过滤网位于引尿管内部的上方。该防止血块堵塞的导尿管，倒刺将引尿管的内部的血块进行缠绕勾住，避免血块掉落，从而造成清除血块效果不理想的情况，清洁刷毛的设计便于将过滤网上方的血块进行包裹缠绕，将其带出，同时清洁刷毛便于对引尿管的内部进行清理。Chinese patent CN207785562U discloses a urinary catheter for preventing blood clots from clogging, including a urinary catheter, a sealing ring, a urinary catheter, barbs and a filter screen. A connecting sleeve is fixed, the sealing ring is located inside the connecting sleeve, a fixed ferrule is connected below the catheter, the support rod is connected with the operating bracelet through the fixing piece installed below, and the inverted The thorns are fixed on the outside of the support rod, and cleaning bristles are installed above the support rod, and the filter screen is located above the inside of the urinary catheter. In the urinary catheter for preventing blood clot blockage, the barbs will wrap and hook the blood clot inside the urinary catheter to prevent the blood clot from falling, resulting in an unsatisfactory effect of removing the blood clot. The design of the cleaning bristles facilitates the removal of the blood clot above the filter Wrap it and bring it out while the cleaning bristles facilitate cleaning the inside of the catheter.
中国专利CN209984772U公开了一种防堵型导尿管，在出尿管处连接有弹性球囊，并在引流管内穿设清淤棒，清淤棒贯穿出尿管、引流管和进尿孔。清淤棒包括棒体、棒头、底座和若干刷毛。棒头为镂空球体，连接在棒体的头部，且比进尿孔大，可防止清淤棒从引流管脱落。底座位于弹性球囊内，并与棒体的尾部连接。刷毛沿棒体的长度方向环形分布在棒体的表面。刷毛之间有足够空隙，清淤棒也足够小，不会阻碍排尿。当引流管内发生堵塞时，可将出尿口处夹闭，并挤压弹性球囊使球囊内液体回流冲入引流管进行冲刷，同时通过弹性球囊捏住底座并抽拉及旋转棒体，通过棒体上的刷毛刷洗引流管内壁，从而彻底清理掉引流管内壁上的血凝块、组织碎屑、絮状残渣等堵塞物，保持引流管畅通。Chinese patent CN209984772U discloses an anti-clogging type urinary catheter, in which an elastic balloon is connected to the urinary outlet tube, and a dredging rod is installed in the drainage tube, and the dredging rod runs through the urinary catheter, the drainage tube and the urine inlet hole. The dredging stick comprises a stick body, a stick head, a base and some bristles. The stick head is a hollow sphere, which is connected to the head of the stick body and is larger than the urine inlet hole, which can prevent the dredging stick from falling off the drainage tube. The base is located in the elastic balloon and connected with the tail of the rod. The bristles are circularly distributed on the surface of the rod along the length direction of the rod. There is enough space between the bristles and the desilting stick is small enough that it doesn't hinder urination. When the drainage tube is blocked, the urine outlet can be clamped, and the elastic balloon can be squeezed to make the liquid in the balloon flow back into the drainage tube for flushing, and at the same time, the elastic balloon can pinch the base and pull and rotate the rod , Brush the inner wall of the drainage tube through the bristles on the rod body, so as to thoroughly clean up the blockages such as blood clots, tissue debris, and flocculent residue on the inner wall of the drainage tube, and keep the drainage tube unblocked.
上述两种专利的缺陷在于：通过倒刺和过滤网进行血块清除，无法彻底清除尿管内部的堵塞物质，其清除效果不好的同时，操作繁琐，并且成本高，若尿管在留置期间发生弯折，极易损坏内部结构，使得该装置无法正常发挥效果。The defect of the above two patents is that blood clots are removed through barbs and filter screens, and the clogging substances inside the urinary catheter cannot be completely removed. While the removal effect is not good, the operation is cumbersome and the cost is high. If the urinary catheter occurs during indwelling Bending can easily damage the internal structure, making the device unable to function normally.
