The invention relates to the field of medical devices, in particular to a multifunctional device for continuously supplying nasal cavity wounds, which consists of a catheter part, an inflatable part and a drug supply part, and the drug supply part includes: a drug injection valve (9), an injection valve Drug tube (6) and drug storage balloon (4). The drug storage balloon (4) is located outside the inflatable balloon (3) in the middle of the nasal catheter (2), and the two are in a nested relationship, the inner surface is the inflatable balloon (3), and the outer surface is the drug storage balloon (4) . The drug storage balloon is made of microporous silica gel film. The invention is mainly used in the repair of nasal passage wounds after nasal cavity surgery, in addition to pressurized hemostasis, fluid drainage, nasal passage cleaning and nasal ventilation, as well as preventing patient nasal cavity healing deviation, nasal septum deviation and postoperative cerebrospinal fluid rhinorrhea, etc. In addition to functions such as complications, the more important thing is that through the drug supply part, hemostatic drugs, painkillers and anti-inflammatory and anti-infective drugs can be continuously used locally on the wound to speed up wound healing and reduce patient pain.
