本发明涉及医疗器械技术领域，是一种双气囊多孔球面状头肛管。The invention relates to the technical field of medical devices, and relates to a double-balloon porous spherical head-anal canal.
背景技术Background technique
随着人口的老龄化，大便失禁的发病率越来越高。大便失禁是医院、疗养院和社区护理中常遇到的问题，尤其在老年人、重危及瘫痪卧床患者中发病率达46～54.4％。大便失禁易造成多种并发症，不仅给患者带来极大的痛苦，引起心理障碍，增加家属的经济负担，也给护理工作带来诸多困难。因此，大便失禁已成为医疗、护理亟需解决的问题。As the population ages, the incidence of fecal incontinence is increasing. Fecal incontinence is a common problem encountered in hospitals, nursing homes and community care, especially in the elderly, critically ill and paralyzed bedridden patients with an incidence rate of 46-54.4%. Fecal incontinence is easy to cause many complications, which not only brings great pain to patients, but also causes psychological barriers, increases the financial burden of family members, and also brings many difficulties to nursing work. Therefore, fecal incontinence has become an urgent problem to be solved in medical treatment and nursing care.
近年来，国内外学者对大便失禁患者的护理进行了不断的探索。一次性尿垫是较早用于大便失禁患者的用具，长期将患者的会阴、肛门、臀部包裹起来，定期更换，但是由于粪便不间断地流出，使局部皮肤常常处于潮湿和代谢产物侵蚀状态，加之经常擦洗，皮肤被磨擦，极易造成局部红肿、湿疹、甚至溃烂，要随时清理流出的粪便，不停地更换护垫，增加了护理工作量和患者的费用。之后，临床上开始用一次性22号粗肛管插入乙状结肠中部18～22cm，肛门周围不固定，另一端装上塑料袋，根据排便的量随时更换塑料袋，但因一次性肛管材质较硬，长期置管患者不能仰卧，睡姿受到限制，舒适度较差，且因肛管没有内固定球囊，肛管容易从肛门滑出，大便也容易从肛门周围溢出，污染局部皮肤和衣被导致压疮的发生。之后，有人采用OB式卫生棉条由肛门塞入，将其留置于肛直肠交界处，遇水膨胀后可截留住粪便，虽然患者感觉舒适无异味，但引流、排气均不畅。有人采用一次性单气囊肛管引流，该单气囊肛管由肛管和气囊组成，肛管呈管状，前后两端开口；气囊包裹于肛管前端的外壁，其充气管埋于肛管壁，另一端游离于肛管壁外与充气阀衔接。使用时，气囊排空，将带有气囊的肛管前端即肛管头部插入直肠15～20cm，使气囊位于直肠与乙状结肠交界处，由充气阀通过充气管给气囊充气，气囊既将肛管和肠壁之间空隙封堵，防止粪便漏出，又可将肛管固定，且此处无便意感受器不易引起排便动作，有利于导管的固定，这样即可有效地将粪便由肛管引出体外。但一次性单气囊肛管存在以下不足：1.肛管前端开口处在插入时容易损伤直肠黏膜，特别是需频繁更换肛管时；2.气囊内压力的大小不易掌握，压力小，气囊与肠壁间的支撑力不够容易滑脱，压力大，气囊对肠壁的压迫大使血流不畅，时间长了会引起肠壁粘膜缺血、糜烂、坏死等症状，所以单气囊需要适时间隔放气10～20min，通常4到6小时放气一次，但放气时容易造成肛管的滑脱和粪便漏出，操作不便且麻烦。In recent years, domestic and foreign scholars have continuously explored the nursing of patients with fecal incontinence. Disposable urine pads are used earlier for patients with fecal incontinence. They wrap the perineum, anus, and buttocks of patients for a long time and replace them regularly. However, due to the uninterrupted flow of feces, the local skin is often in a state of moisture and metabolite erosion. In addition, frequent scrubbing and rubbing of the skin can easily cause local redness, swelling, eczema, and even ulceration. It is necessary to clean up the feces that flow out at any time, and constantly replace the pads, which increases the nursing workload and the patient's expenses. Afterwards, a disposable 22-gauge thick anal canal was inserted clinically into the middle of the sigmoid colon for 18-22 cm. , patients with long-term intubation cannot lie on their backs, the sleeping position is limited, and the comfort level is poor, and because the anal canal does not have an internal fixation balloon, the anal canal is easy to slip out of the anus, and stool is easy to overflow from around the anus, polluting the local skin and clothing lead to pressure sores. Later, some people used OB-style tampons to insert through the anus and leave them at the junction of the anorectum. When they swell with water, they can trap feces. Although the patients feel comfortable and have no peculiar smell, the drainage and exhaust are not smooth. Some people use one-time single-balloon anal canal drainage. The single-balloon anal canal is composed of anal canal and air sacs. The anal canal is tubular with openings at both ends. The other end is free from the wall of the anal canal and connected with the inflation valve. When in use, the air bag is emptied, and the front end of the anal canal with the air bag, that is, the head of the anal canal, is inserted into the rectum for 15 to 20 cm, so that the air bag is located at the junction of the rectum and the sigmoid colon, and the air bag is inflated by the inflation valve through the inflation tube. The gap between the bowel and the intestinal wall is blocked to prevent feces from leaking out, and the anal canal can be fixed, and there is no defecation sensor here, which is not easy to cause defecation action, which is conducive to the fixation of the catheter, so that the feces can be effectively drawn out of the body from the anal canal. However, the disposable single-balloon anal canal has the following disadvantages: 1. The front opening of the anal canal is easy to damage the rectal mucosa during insertion, especially when the anal canal needs to be replaced frequently; The supporting force between the intestinal wall is not enough, it is easy to slip, and the pressure is high. The pressure of the air bag on the intestinal wall makes the blood flow poor. After a long time, it will cause symptoms such as ischemia, erosion, and necrosis of the intestinal wall mucosa. Therefore, the single air bag needs to be deflated at appropriate intervals. 10 to 20 minutes, usually every 4 to 6 hours to deflate, but it is easy to cause slippage of the anal canal and leakage of feces during deflation, which is inconvenient and troublesome to operate.
发明内容Contents of the invention

The anal canal is divided into two parts, the head and the body. The anal canal head is in the shape of a porous spherical surface, with or without 3-5 grooves around the spherical surface, and drainage holes are provided on the top and surrounding of the spherical surface, and the anal canal body is tubular; Two air sacs are wrapped sequentially on the outer wall of the body at the rear edge of the head of the anal canal. The inflatable tubes of the two air sacs are respectively buried in the wall of the anal canal body. The outside of the tube wall is connected with the air pressure indicating balloon; the air pressure indicating balloon is composed of a balloon, an inflation valve on one side of the balloon and a pressure tester at the end of the balloon. The gas pressure is the same, and the pressure can be read from the pressure tester, so that the inflation amount of the airbag can be controlled, and the airbag can be alternately inflated and deflated at the right time. A numerically controlled airbag pressure monitor can also be connected to the two inflation valves to automatically control the inflation pressure of the airbag and the time for alternately filling and deflated the two airbags in a numerically controlled manner, making the operation more scientific and convenient.
本发明的优点在于：1)肛管头部呈多孔球面状，其四周圆润光滑，插入时对直肠黏膜损伤小；2)肛管头部球面顶部和四周各设有引流孔，便于稀便流入肛管，且利于腹胀患者排气；3)双气囊交替充、放气，防止引起肠道黏膜内壁由于长时间受压而出现粘膜缺血、糜烂、坏死等症状，同时也防止了气囊放气时肛管的滑脱；4)压力测试器能随时监测气囊内的压力，可控制气囊的充气量；5)如果采用数控气囊压力监控仪，可使操作更为科学简便。The advantages of the present invention are: 1) the head of the anal canal is in the shape of a porous spherical surface, and its surroundings are round and smooth, causing little damage to the rectal mucosa during insertion; 2) the top of the spherical surface of the anal canal and its surroundings are each equipped with drainage holes to facilitate the flow of loose stools 3) The double airbags are alternately inflated and deflated to prevent the inner wall of the intestinal mucosa from being caused by long-term pressure, such as mucosal ischemia, erosion, necrosis, etc., and also prevent the deflation of the airbags 4) The pressure tester can monitor the pressure in the airbag at any time, and can control the inflation of the airbag; 5) If the numerical control airbag pressure monitor is used, the operation can be more scientific and convenient.
