The main purpose of gastric tube insertion is to facilitate the injection of liquid food, water and medicine to the patient through the gastric tube to ensure that the patient can take in enough nutrition and medicine, while endotracheal intubation is mainly to help the patient breathe and improve ventilation function. The traditional method of fixing gastric tubes and endotracheal tubes is to fix the endotracheal tube and gastric tube on the dental pad with tape, and then directly stick them to the cheeks on both sides of the patient. The above method is cumbersome to operate and has poor comfort. For inexperienced nursing staff, there is also the risk of unstable fixation.
