This invention relates to a postoperative nasal cavity care device, belonging to the field of medical device technology. It includes a silicone nasal plug, a quantitative filter airflow valve, a pressure fixation plate, a nasal wing fixation splint, a micro-liquid pump, and a micro-controller. This invention provides a care device that simultaneously achieves flexible and comfortable pressure for hemostasis and dressing changes, as well as automated assisted nasal breathing. The silicone nasal plug, combined with an inflatable support sleeve, facilitates flexible and comfortable pressure for hemostasis and dressing changes, significantly reducing patient discomfort during postoperative nasal cavity care. Furthermore, the smooth and soft silicone avoids tearing the wound and causing secondary injury and infection due to pulling. The combination of a respiratory rate sensor and a quantitative filter airflow valve helps maintain unobstructed breathing after surgery by conforming the device to the patient's own breathing rhythm.
