[0002] At present, there are many medical supplies for the treatment of anus or women's vaginal diseases, such as the multifunctional cotton plug with the patent application number 89218292, which is characterized in that the medicine is adhered to the cotton plug and is provided with a backguy. It is more difficult to diffuse out of the medium, so that the medicine can not be fully utilized; the application number is 94223569, a new type of gynecological therapeutic device, which is characterized in that it is composed of a plug wrapped in capsule medicine and a propeller composed of a tube wall, a piston and a push rod , though have the effect and the effect of curing the disease, complex structure, cost is high; Application No. is 91210449 suppository propulsion treatment device, it is characterized in that the rear end of catheter inserts propulsion tube, and the front portion of catheter is equipped with suppository capsule, The rear part is equipped with a pusher blocking strip with a pull wire, which has the advantage of being able to conveniently insert the medicine suppository into the body without touching hands, but it also has the problems of many parts, complex structure, high cost and high cost; the application number is 92237222 Carrier suppository, the main problem of its existence is that the production process is complex, the raw materials used are many, and the cost is high; the application number is 96239493 new type medicinal suppository, which is outstanding in the prior art and has been put into production, and it has the advantages of less material , simple manufacturing process, low cost, and full use of drugs when used, but from the perspective of patients and professionals, there are still the following shortcomings: (1) The volume of the cotton plug core is too large and the shape is not scientific enough , so that ① the dosage of the drug-containing carrier matrix is ​​too small; ② the thickness of the drug-containing carrier matrix outside the cotton plug core is thin and extremely uneven; ③ the effective action time of the drug is limited; ④ frequent dressing changes increase the probability of infection, It also increases the chance of contusive lesions (such as cervical erosion); ⑤ the effective action time of the drug is not suitable for diseases that are not suitable for frequent dressing changes, such as cervical erosion, cervical cancer, rectal cancer, nasal polyps, nasal cancer, etc.; (2) The shape of the drug-containing carrier matrix is ​​limited, so that the positioning is not good
