Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a quantitative ear and nose medicine drop device. Background Art

[0002] When suffering from ear or nasal diseases, it is often necessary to drip medicine into the ear canal or nasal cavity for treatment. For patients who need long-term treatment, a quantitative medicine drip device is often needed to more accurately control the metering of the medicine, facilitate continuous drug administration, and thus improve the treatment effect.

[0003] Most existing drug drop devices use plastic bottles of eye drops to directly squeeze and drip the medicine.
