Abstract

The invention provides an anorectal drug delivery device, the front part of the drug delivery tube is used to be inserted into the anorectum and the bottom of the drug delivery channel of the front part is closed and the side wall has a drug outlet hole; the outside of the front part is also fixedly covered with An elastic bullet-shaped hollow elastic sleeve, the end of the elastic sleeve facing away from the warhead is fixedly sleeved on the surface of the front section, the direction of the bullet head of the elastic sleeve is sleeved at the free end of the front section and the free end is integrally embedded in the side of the center of the bullet head of the elastic sleeve Inside the wall; the side wall of the elastic sleeve facing the drug outlet hole is integrally and protrudingly provided with a drug cartridge, one end of the drug cartridge is connected to the drug outlet hole, and the other end runs through the drug outlet hole. The side wall of the elastic sleeve is used for contacting the inner wall of the anorectum, and an annular expansion chamber connected with the inflation device for containing air is formed between the elastic sleeve and the front section of the administration tube. The anorectal drug delivery device of the present invention can more accurately realize drug delivery to the affected part of the anorectum, reduce the waste of medicinal liquid, and improve the curative effect.

Description

technical field [0001] The invention relates to the technical field of anorectal treatment, and more specifically relates to an anorectal drug delivery device. Background technique [0002] During anorectal treatment, it is often necessary to directly administer medicine to the affected part of the anorectal inner wall, and send a medicinal liquid. At present, medical staff usually use the existing drug delivery device to directly insert into the anorectum for extensive drug administration. This drug delivery device only has a drug delivery port near the end so that the liquid medicine can flow out after reaching a predetermined depth. However, The outflowing medicinal liquid will flow in all directions on the inner wall of the anorectum, and the medicinal liquid will flow through the healthy parts, so that the medicinal liquid will not concentrate in the affected area and cannot be fully absorbed by the affected area, which not only wastes the medicinal liquid, but also gre...
