[0002] The Department of Enterology is a department that specializes in the research and treatment of constipation, anal fissure, anal fistula, anal abscess, anal stenosis, hypertrophy of anal papillae, perianal eczema, mixed hemorrhoids, internal hemorrhoids, and external hemorrhoids. Its research range of diseases mainly focuses on diseases of the organs at the end of the digestive system, which is 8-12 cm from the anus to the rectum. In real life, more and more people have anorectal diseases. Generally, when applying medicine to the anus of anorectal patients, medical staff need to do it manually.

[0003] When applying medicine to the anus of anorectal patients, a special medicine applying device is required. However, the existing anal medicine applying device generally directly inserts the medicine applying head of the device into the rectum deep in the anus of the patient to administer the medicine. Since the human anus is tight, the medicine applying tube moves back and forth at the anus during the medication process, which increases the pain of the patient. In addition, the rectum is not cleaned before applying the medicine, and the medicine cannot be evenly distributed along the rectum, which affects the effect of the anorectal absorption of the medicine.

A spray chamber 211 is provided inside the hemispherical portion 215. The spray chamber 211 is connected to the inside of the medicine tube 2, and a plurality of spray holes 212 are evenly provided on the spray chamber 211. Liquid can enter the spray chamber 211 through the medicine tube 2, and then be evenly sprayed out through the spray holes 212; a liquid suction chamber 213 is provided inside the columnar portion 216, and a plurality of liquid suction holes 214 are evenly provided on the surface of the liquid suction chamber 213, which are used to absorb the cleaning liquid inside the anorectal, clean the inside of the rectum, and avoid a large amount of cleaning liquid remaining in the rectum, and a retractable liquid suction tube 22 is fixedly connected to the columnar portion 216. The liquid suction tube 22 is a sealing structure, and an avoidance groove 62 installed in cooperation with the liquid suction tube 22 is provided on the mouthpiece 6 to avoid the liquid suction tube 22 from being retracted when the liquid suction tube 22 is retracted. In contact with the anorectum; one end of the suction tube 22 is sealed and fixedly connected to the suction chamber 213; an adsorption chamber 61 is arranged inside the mouthpiece 6, and the adsorption chamber 61 is arranged near the limit block 8, and the other end of the suction tube 22 is sealed and fixedly connected to the adsorption chamber 61; wherein, a ring-shaped sealed suction bag 7 is installed on the frame body 1, and the suction bag 7 can be made of rubber material, and the suction bag 7 can automatically restore deformation. The suction bag 7 is in a saturated state when not subjected to external force, and the suction bag 7 is sealed and connected to the adsorption chamber 61 through the adsorption tube 9, and the adsorption tube 9 does not affect the insertion of the mouthpiece 6 into the anus, and a pressing frame 23 is fixedly connected to the upper medicine tube 2, and when the upper medicine tube 2 moves deep into the rectum, the pressing frame 23 will crush the suction bag 7; the surface of the suction bag 7 is sealed and connected with an openable sealing door 71, and the inside of the suction bag 7 can be cleaned through the sealing door 71.

[0033] During specific implementation: before use, clean the inside of the liquid absorption bag 7. After the mouthpiece 6 is inserted into the patient's anus, the upper medicine tube 2 moves deep into the patient's rectum, and the cleaning liquid is sprayed out through the spray hole 212 to clean the inner wall of the rectum. At the same time, when the upper medicine tube 2 moves, it drives the pressing frame 23 to crush the liquid absorption bag 7; when the upper medicine tube 2 is withdrawn, the liquid absorption bag 7 gradually recovers its deformation and is saturated, and the cleaning liquid in the rectum is absorbed into the liquid absorption chamber 213 through the liquid absorption hole 214, and then enters the adsorption chamber 61 through the liquid absorption tube 22, and finally is sucked into the liquid absorption bag 7 through the adsorption tube 9. After use, the liquid absorption bag 7 needs to be cleaned in time, so that after the upper medicine tube 2 moves back and forth, the cleaning liquid is sucked out in time after cleaning the rectum, thereby avoiding a large amount of cleaning liquid remaining in the rectum.
