[0002] As we all know, obstetrics and gynecology is one of the four major disciplines in clinical medicine. It mainly studies the etiology, pathology, diagnosis and prevention of diseases of the female reproductive organs, and the physiological and pathological changes of pregnancy and childbirth. When treating patients, medical staff need to use medication devices to treat the lesions in the vagina.

[0003] The patent with application number CN201920472462.1 discloses a gynecological and obstetric postpartum medication device, including a medicine storage cartridge and a medicine spray cartridge, a baffle is provided at one end of the interior of the medicine storage cartridge, and a piston slidably connected thereto is provided inside the medicine storage cartridge, a medicine outlet is provided at the middle position of the baffle, and a push rod is connected to one end of the piston relative to the baffle, which passes through the medicine storage cartridge and extends to one side of the outside of the medicine storage cartridge.

[0004] Although the device improves comfort to a certain extent, after the device sprays the drug through the spray hole, the drug flows back to the lower part of the vagina under the action of gravity. Therefore, the diseased part in the upper part cannot be exposed to the drug for a long time, so the drug absorption efficiency is not very good and there is room for improvement.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a medicine feeding device, which has the following beneficial effects:

[0016] When there is a lesion above the patient's vagina, the drug delivery tube only needs to be slid into the vagina so that the opening is aligned with the lesion. At this time, the rotating rod and the sliding block can be operated so that the drug guide groove covers the first row of drug holes, so that all the drugs discharged from the first row of drug holes can be discharged to the upper part of the sliding block, flow to the opening of the drug delivery tube, and contact the lesion. At this time, it can remain motionless so that the lesion is fully in contact with the drug, thereby increasing the time for the lesion to absorb the drug, thereby improving the absorption efficiency.
