Description

medical enema

technical field

The utility model relates to the field of medicine, more specifically, the utility model relates to a medical enema.

Background technique

At present, enema diagnosis and treatment is a commonly used clinical method, and is often used in drug retention enema and contrast agent (contrast agent) enema. With the development of medical imaging, barium (air) enema reduction under X-ray, water pressure enema reduction under ultrasound monitoring, and early diagnosis of intestinal tumors in the treatment of intussusception in children, due to the characteristics of non-surgical diagnosis and treatment and non-invasive been increasingly applied. At present, the commonly used clinical enema devices include ordinary anal canal, disposable anal canal, and latex balloon catheter instead of the anal canal, but they can only perform a simple injection function, and cannot effectively monitor, Adjust the enema pressure and rate of fluid infusion. The pressure is often adjusted by controlling the linear distance between the liquid surface and the anus. The farther the liquid surface is from the anus, the greater the perfusion pressure. If the liquid surface is less than 30cm from the anus, it is a low-pressure enema, which is suitable for retention enema. The flow rate of the solution at low pressure is also slow, and on the contrary, the high pressure will cause damage to the intestinal mucosa or lead to premature discharge of the perfused liquid. The monitoring and control of enema pressure can improve the effectiveness and safety of diagnosis and treatment operations.

According to the anatomical and physiological characteristics of the human body, the length of the anal canal is about 3-4 cm, and the length of the rectum is about 12-15 cm. Conventional enema method, the length of the anal canal insertion is 10-15cm, the enema liquid just flows into the rectum, when the enema liquid accumulates in the rectum to 150-200ml, and when the pressure in the rectum is greater than 7.3KPa, the rectal wall receptors are strongly excited and pass through the nerve The reflex immediately causes the defecation reflex to produce the desire to defecate. Retention enema uses a thinner anal canal to infuse at low pressure to keep the enema liquid for a longer period of time. The insertion depth is 20-25 cm. The liquid easily reaches the rectum through intestinal peristalsis, causing defecation emission, and is excreted in a short period of time, directly affecting the effect of diagnosis and treatment.
