Technical Field

[0001] The utility model relates to the technical field of micro-instruments, in particular to an ear medication device for otolaryngology. Background Art

[0002] Ear health is very important to people. Maintaining good hearing can enable people to live, work and communicate better. Therefore, when there are health problems with the ears, it is often necessary to administer medicine to the inside of the ear hole. The medicines used for ear hole administration include solid and liquid medicines. When liquid medicines are administered to the inside of the ear hole, existing devices have a greater risk of causing damage to the ear hole. In addition, sometimes more than one liquid medicine needs to be administered, and the operation of existing devices for administering more types of liquid medicines is more complicated, time-consuming and labor-intensive. Finally, some liquid medicines are easily volatile. Therefore, when existing devices are used to administer medicine to the ear, the liquid medicine is exposed to the outside air for a long time, which causes the drug properties to be reduced, resulting in unsatisfactory drug efficacy.

[0003] In order to solve the multiple technical problems existing in the aforementioned ear drug delivery process, it is urgently needed to provide an ear drug delivery device for otolaryngology. Summary of the invention
