Description

Technical Field

[0001] The utility model relates to the technical field of breathing trainers, in particular to a breathing trainer for patients undergoing nasal surgery before surgery. Background Art

[0002] Transnasal surgery is an innovative surgical approach. For example, the innovative transnasal approach developed by Peking University Third Hospital offers new hope for patients with basilar invagination. Transnasal surgery can effectively treat basilar invagination and other bone deformities at the craniocervical junction. Nasal packing is required after transnasal surgery, and patients are trained to breathe through their mouths before surgery to avoid breathing difficulties caused by the gauze packing. After surgery, the patient's breathing pattern changes from nasal to oral breathing. This discomfort can cause breathing difficulties and a feeling of shortness of breath, leading to changes in comfort and mood, such as anxiety and anxiety. Postoperative pain can also affect sleep quality, and excessive breathing can increase nasopharyngeal pressure and cause the packing to loosen and dislodge. Currently, pinching exercises or simple packing through oral breathing are used, but these simple packing methods are prone to dislodgment. Choosing the appropriate packing material and size for optimal comfort is challenging, and pinching exercises require the patient to maintain a constant hand position, which is extremely inconvenient.
