Problems solved by technology

[0005] 1. Nasal endoscopic hemostasis: At present, nasal endoscopic hemostasis is mainly used for hemostasis after otolaryngology surgery. Most of the hemostasis during the operation is complete and the field of vision is clear. This method is feasible for preventive wound treatment, but it is often used for spontaneous bleeding. The field of vision is blurred, and it is difficult to operate, which is even more difficult. Because of the expensive equipment and few specialists who can operate it, it cannot be used as a daily emergency and home use

[0006] 2. Pressure hemostasis: Iodoform gauze is often used to stuff the nasal cavity to stop bleeding. This method is effective, but because the operation of the posterior nasal cavity is difficult, a specialist is required to operate, and the operation is time-consuming.
