Hemorrhoids or called hemorrhoids are the most common anus diseases clinically, usually called "ten men's and nine hemorrhoids", "ten women and ten hemorrhoids", and can be seen in a wide group of patients with hemorrhoids. Hemorrhoids are well documented in traditional Chinese medicine. The english man Thomson proposed in 1975 a modern concept of hemorrhoids: hemorrhoids are the anal cushion at the lower end of the rectum and appear pathologically hypertrophic. Hemorrhoids can be classified into internal hemorrhoids, external hemorrhoids and mixed hemorrhoids according to the occurrence sites. Internal hemorrhoids are currently considered to be the pathological changes or shifts in the support structure of the anal cushion (anal canal vascular cushion), vascular plexus and arteriovenous anastomosis. The good hair parts of internal hemorrhoids are points 3, 7 and 11 of lithotomy. Mainly manifested by bleeding and herniation. A common clinical symptom of internal hemorrhoids is bleeding after intermittent urination. Some patients may be accompanied by difficult defecation. Pain occurs when internal hemorrhoids combine to develop thrombosis, incarceration, and infection. External hemorrhoids are pathological expansions or thrombosis of the distal subdermal vascular plexus of the dentate line. The mixed hemorrhoid is a mixture of internal hemorrhoid and external hemorrhoid. However, in the process of conservative treatment of hemorrhoids, the medicine needs to be smeared on the affected part, so that the medicine is inconvenient to smear, and meanwhile, the adhesion effect after the medicine is smeared is poor, so that the treatment of a patient is affected, and therefore, a disposable medicine feeding device extruder is proposed.
