The utility model relates to the technical field of medical instruments, which is a double-airbag porous spherical head-anal canal.

Background technique

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.

In recent years, scholars at home and abroad 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 not smooth. 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, but it is easy to cause slippage of the anal canal and leakage of feces during deflation, which is inconvenient and troublesome to operate.

Contents of the invention

The purpose of this utility model is to provide a device that is easy to operate, has little damage to the rectal mucosa during insertion, can control the inflation pressure of the air bag, and can be filled and deflated alternately by two air bags to avoid symptoms such as ischemia, erosion, and necrosis of the intestinal wall mucosa. The double-balloon porous spherical head of the anal canal appears.

The utility model is composed of anal canal, two air bags and an air pressure indicating balloon. 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.

The utility model has the advantages of: 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 respectively provided with drainage holes, which is convenient for 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. 4) The pressure tester can monitor the pressure in the airbag at any time, and can control the inflation amount of the airbag; 5) If the numerical control airbag pressure monitor is used, the operation can be more scientific and convenient.
