Abstract

The invention relates to an external auditory canal directional delivery anti-epidemic device with a height of 20-30mm, a lower part diameter of 12-22mm and a upper part diameter of 6-12mm, the anti-epidemic device has an upper part with a round solitary, is in the shape of a bullet and implanted with drugs. The anti-epidemic device provided by the invention is pinched into a slender strip, the slender strip is plugged into external auditory canals of two ears, and the anti-epidemic device automatically rebounds in the external auditory canals and makes contact with the walls of the external auditory canals and ear hairs. According to the invention, the drug implanted of the anti-epidemic device delivered in external auditory canal is not only absorbed by external auditory canal skin cells, but also the drug information of implanted drug smell (wave) , the drug smell (wave) is sensed by the external auditory canal cells and ear hairs, and the drug smell (wave) is delivered to a human body and is further delivered to nasal olfactory nerve cells through eustachian tubes of ears, so that the human body biological information effect is generated to effectively treat human body diseases.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to an anti-epidemic device for continuous directional delivery of outer ear medicine and a preparation process thereof. Background technique [0002] Infectious diseases were called plague in ancient times, and the routes of drug administration to protect susceptible people include intravenous subcutaneous injections, oral administration, nasal inhalation, eye drops, and transdermal patches. There are ear drops for otic administration, which are dripped into the middle ear to absorb the drug. Chinese patent 102186528 has invented a drug delivery device for the inner ear, which is an injection device with a handle and a puncture point, and injects drugs through the cochlear round window membrane of the inner ear. Chinese patent 109200450 discloses a continuous drug delivery device for the inner ear, which includes a housing, a drug storage cylinder, a scale, an adjustment plate, ...
