Description

technical field [0001] The invention relates to the field of medical appliances, in particular to an ear-hook nasal cavity drug delivery device and a drug delivery method. Background technique [0002] After conventional nasal cavity surgery, follow-up hemostasis, analgesic and other treatment and care are often required. Usually, gauze or hemostatic sponge is stuffed in the nasal cavity of the patient. For the analgesic method in such cases, analgesic drugs are often injected intravenously as a However, the effect is often not good because of the dose.
