Description

Enema device

Technical Field

The invention belongs to the technical field of enemas, and particularly relates to an enemator.

Background

Elderly people in advanced age and long-term bed rest have high constipation incidence, which not only brings great pain to patients, but also increases difficulty for nursing staff. Traditional constipation relieving methods, such as adopting enema and glycerin enema to accommodate anus, often cannot reach a certain depth due to short and hard bottle mouth, cause liquid medicine to easily flow back out to influence the treatment effect, and also easily cause injury of anal canal mucosa to increase pain of patients. In the existing tool for clinical enema, a disposable enema bag is used for enabling liquid to flow into an anus by utilizing height pressure difference, when the pressure in an intestinal canal is overlarge, the liquid cannot flow into the anus continuously, and in addition, the anal sphincter of the old is loosened, the liquid medicine cannot exert the function in time after enema and overflows from the anus, so that the effect cannot be achieved; in addition, the diameter of the anal tube is large and the anal tube is not deeply inserted, so that the anal tube has large irritation to the anus and can easily slide out, a nursing staff needs to support the anal tube by hands, the working efficiency is low, the front end of the anal tube can only reach the junction of the rectum or the rectum and the sigmoid colon (the length of the rectum is 150mm and the length of the sigmoid colon is 400 mm and 450 mm), a large amount of enema is gathered in the rectum, but dry and hard excrement in the sigmoid colon cannot be sufficiently softened, the stimulation of the liquid to the rectum can cause a strong defecation reflex, and the dry and hard excrement can damage the sigmoid colon. Therefore, it is important to solve the above problems.
