[0002] Anorectal refers to the anus and rectum. Anorectal disease is a common and frequently occurring disease. Broadly speaking, various diseases occurring in the anus, anal canal, and large intestine are called anorectal diseases. There are more than 100 common diseases. A census of people aged 20-50 years showed that the rate of anorectal disease patients was as high as 72%, with women slightly higher than men.

[0003] The invention patent with the patent number CN118787846A discloses an anorectal drug delivery device, which specifically includes an insertion head and an L-shaped seat, wherein the bottom of one end of the L-shaped seat is respectively threadedly connected with a medicine bottle and a filling liquid bottle, a through hole for placing the insertion head is provided on the upper surface of the other end of the L-shaped seat, a heat-resistant seat for heating the insertion head is fixed inside the other end of the L-shaped seat, and a first installation cavity and a second installation cavity for placing a first micro-liquid pump, a second micro-liquid pump and a third micro-liquid pump are provided inside one end of the L-shaped seat: the top and side of the insertion head are provided with concave holes for installing the liquid medicine spray head, and the sides of the insertion head are symmetrically provided with grooves for installing multiple groups of semi-circular expansion airbags, and each two symmetrically distributed semi-circular expansion airbags form a group. The invention uses multiple groups of semi-circular expansion airbags to form a closed area for applying medicine to the affected area after expansion, thereby ensuring repeated contact between the liquid medicine and the anorectal surface and ensuring the accuracy of the medicine application.

[0004] The above-mentioned device forms a closed area for applying medicine to the affected area after multiple groups of semi-circular expansion balloons are inflated.
