[0002] Gastrointestinal drug administration is currently the most commonly used method for treating digestive diseases. Gastrointestinal drug administration requires a drug administration auxiliary device that cooperates with a syringe to extend into the esophagus for drug administration. Chinese utility model CN213667470U discloses an esophageal drug administration auxiliary device for gastroenterology. The esophageal drug administration auxiliary device for gastroenterology is provided with a support block A and a support block B, and a knob is used to drive a screw rod to rotate. The screw rod is provided with threads of different rotation directions and is respectively threadedly connected to two movable seats, so that when the screw rod rotates, the two movable seats will move in opposite directions. When the two movable seats move inward, the angle between the two hinged support rods will change from large to small, so that the support block A at the upper end of the support rod is pushed up, so that the patient's upper and lower jaws will always remain open, making it easier for medical staff to insert the hose into the patient's esophagus for drug administration. The tooth protection component will protect the patient's teeth when he is uncomfortable, and at the same time prevent the hose from being bitten. However, the esophageal drug administration auxiliary device for gastroenterology still has the following problems during use:
