How to make the patient have the safest, comfortable and high-quality anesthesia during anesthesia to complete an operation. This is due to the mutual assistance, cooperation and preoperative evaluation of anesthesiology and surgeons. Preoperative preparation is of great significance to anesthesiology and patients.

At present, the anesthesia can be performed by general anesthesia through the endotracheal tube. This kind of anesthesia is administered intravenously to allow the patient to achieve intraoperative pain relief during surgery, complete relaxation of muscles, and adjustment of the concentration of anesthetic gas to maintain the patient's blood pressure. The heartbeat relaxes the muscles of the patient while allowing the trachea to keep the patient's breathing smooth. Most patients who need to use this anesthesia have longer operation time, and some open brain, thoracic surgery and nerve surgery require deeper anesthesia to complete the operation.

Most of the above-mentioned methods of general anesthesia through the endotracheal tube are inserted into the endotracheal tube through the mouth, but when the oral cavity needs surgery, the endotracheal tube needs to be inserted through the nasal passage, and then the anesthetic agent is input to the nasal tube, and the nasal tube is delivered for anesthesia. The drug reaches the respiratory tract of the patient to achieve the effect of anesthesia. When the nasal tube is inserted into the nasal cavity of the patient, the insertion end of the nasal tube is a diagonal gap. When the nasal tube is inserted into the nasal cavity, the insertion end of the nasal tube may scratch the nasal cavity and the posterior pharyngeal cavity, and the nasal canal passes through the nasal cavity. The surface of the nasal canal will stick to the secretions in the nasal cavity. When the nasal cannula is inserted into the trachea, it will cause the trachea to be infected with the secretions in the nasal cavity.

In view of the above problems, the present invention provides a protective device for a nasal tube, which is mainly provided with a protective sleeve on the insertion end of the nasal tube to prevent the insertion end of the nasal tube from scratching the inside of the nasal cavity when the nasal tube is inserted into the nasal cavity.
