技术领域technical field

本实用新型涉及一种肾脏灌注管。The utility model relates to a kidney perfusion tube.

背景技术Background technique

目前，国内每年都有大量尿毒症患者需要进行肾脏移植手术，而且患者数量还在增加。器官移植是救治此类病人的最好办法。器官移植手术中器官的活性非常重要，器官的活性决定了移植手术的质量，同时决定了器官移植后器官功能的恢复状况。由于离体器官在常温下(热缺血)短期内即趋向失去活力，因此需要对离体器官进行低温保存(冷缺血)。具体做法是取肾前先用4度肾脏保护液灌注肾脏，使其去血流。目前还没有专门用于器官移植使用的人体器官灌注管，在进行器官灌注时，常用灌注方法是24-26号双腔尿管改装，在尿管前端剪小孔，然后经腹主动脉分叉上方做一切口，将尿管置入腹主动脉，跨过腹主动脉内分肾动脉的近心端，然后打气囊，阻断近心端血流，腹主动脉分叉上方的切口用7号丝线结扎，使中间段血管封闭，再通过尿管注入肾脏保护液。但是由于制作者的改造手法不同，灌注管之间的差异较大，规格不统一，这存在着操作复杂、费时等问题，影响手术效率；且结扎时若用力较轻则，连接处结构简单，密封性差，灌注时由于灌注液自身压力，必然出现灌注液溢出等问题。为此中国专利CN203075438U提供了一种人体器官灌注管，该人体器官灌注管，包括管体，管体上沿其头部至其尾部的方向上依次设置有气囊、出水孔和卡环，在管体的尾部还分别设置有与气囊相连通的气囊外口和与出水孔相连通的进水孔。存在的问题之一是无法对灌注速度、灌注时间进行控制，影响灌注效果；存在的问题之二是无法在灌注时排除灌注液中的气泡；存在的问题之三是卡环密封易对机体照成损伤。At present, a large number of uremic patients in China need kidney transplantation every year, and the number of patients is still increasing. Organ transplantation is the best way to save such patients. The activity of organs is very important in organ transplantation. The activity of organs determines the quality of transplantation and the recovery of organ function after organ transplantation. Because isolated organs tend to lose their vitality in a short period of time at normal temperature (warm ischemia), cryopreservation of isolated organs is required (cold ischemia). The specific method is to perfuse the kidney with 4-degree kidney protection solution before taking the kidney to remove blood flow. At present, there is no human organ perfusion tube specially used for organ transplantation. When performing organ perfusion, the common perfusion method is to modify the 24-26 double-lumen urinary catheter, cut a small hole at the front end of the urinary catheter, and then bifurcate through the abdominal aorta Make an incision above, place the catheter into the abdominal aorta, cross the proximal end of the renal artery in the abdominal aorta, and then inflate the balloon to block the blood flow at the proximal end. No. silk suture was ligated to seal the blood vessels in the middle section, and then the kidney protection solution was injected through the urinary catheter. However, due to the different modification methods of the manufacturers, the differences between the perfusion tubes are large, and the specifications are not uniform. This has problems such as complicated operation and time-consuming, which affects the efficiency of the operation; The sealing performance is poor, and problems such as overflow of the perfusate will inevitably occur due to the pressure of the perfusate itself during perfusion. For this reason Chinese patent CN203075438U provides a kind of human organ perfusion pipe, this human organ perfusion pipe, comprises pipe body, is provided with air bag, outlet hole and clasp successively on the pipe body along the direction from its head to its tail, in the pipe The tail part of the body is also respectively provided with an air bag outer port communicating with the air bag and a water inlet hole communicating with the water outlet hole. One of the existing problems is that it is impossible to control the perfusion speed and perfusion time, which affects the perfusion effect; the second problem is that it is impossible to eliminate the air bubbles in the perfusate during perfusion; the third problem is that the snap ring seal is easy to expose the body. into damage.
