Problems solved by technology

[0003] When it is necessary to apply medicine to the upper part of the nasal cavity of the ENT department, the existing method of applying medicine is usually sprayed directly through a medicine spraying device, resulting in a limited spraying range, poor medicine application effect, and the length of the nozzle cannot be adjusted during use, thus As a result, it is difficult to apply medicine deep in the nasal cavity, and it is inconvenient to use, and the existing medicine application device cannot adjust the amount of medicine when applying medicine, which is prone to insufficient or overdose of medicine, resulting in poor use effect and affecting the patient's health. Health recovery effect
