An anorectal inspection and drug delivery device capable of precise drug delivery

Abstract

The invention relates to an anorectal inspection and drug delivery device capable of realizing precise drug delivery, which includes a fixed base plate, a rotating disc for adjusting the degree of expansion, N arc-shaped expansion plates for realizing anal expansion, and a The drug administration assembly, the fixed base plate includes a base plate, an outer cylinder covered on the base plate, and an annular plate arranged inside the outer cylinder, the rotating plate includes a round cover and N control blocks arranged in the round cover, and the drug delivery Assemblies include multiple dosing inserts, dosing main tubes, dosing manifolds, and multiport valves. The anorectal examination and drug delivery device of the present invention can not only adjust the degree of dilation according to different patients, but also can precisely deliver drugs locally to patients, and the therapeutic effect is better.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anorectal examination and drug delivery device capable of realizing precise drug delivery. Background technique [0002] Anorectal disease is a common and frequently-occurring disease unique to humans. In a broad sense: various diseases that occur in the anus and large intestine are called anorectal diseases, and there are more than 100 common diseases. In a narrow sense: there are more than 30 kinds of diseases that occur in the anus and rectum, such as: internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, anal fissure, anal fistula, perianal abscess, anal skin disease, anal sinusitis, proctitis, Rectal ulcer, export constipation, rectal prolapse, rectocele, rectal mucosal prolapse, anorectal stenosis, anal incontinence, anal canal cancer, rectal cancer, anal papilloma, rectal polyps, anorectal tuberculosis, anal neurosis, Condyloma acuminatum, anorectal c...

Problems solved by technology

[0003] The anorectal dilator is a commonly used medical device in the treatment of anorectal diseases. During the treatment process, it is necessary to inspect the inside of the anus and perform drug administration operations. The existing dilators are generally of fixed size, and are directly inserted into the anus of the patient when expansion is required. In the canal, if the size of the dilator is not appropriate, it will cause discomfort to the patient and even cause injury to the anus

In addition, the drug administration operation is usually to use the drug tube to connect the drug tube to administer the drug through the anus and rectum, which is inconvenient and cannot be administered locally to the patient, and the therapeutic effect is quite poor.
