they are used for the insufficient effect of a cleansing enema, in debilitated patients, and also if necessary, repeated washing of the colon, for example, before intestinal endoscopy. Instead, Esmarch’s mugs use a large funnel. A long rubber tip (20-30 cm) is inserted into the connecting rubber tube, which is inserted into the intestine to a depth of 1015 cm. The funnel filled with water is raised up to a height of 1-1.5 m so that water penetrates the intestine; as soon as the water level drops to the bottom of the funnel, it is quickly lowered downward, while the liquid from the intestine with an admixture of feces and gases enters the funnel, it is poured out, and the funnel is filled with clean water. Such washing is carried out 10-15 times (until there is no stool impurities in the washing water).
