[0002] A gastric tube is a clinical medical device that is inserted through the nostrils and reaches the stomach through the pharynx and esophagus. It can be used to extract gastric juice, inject liquid into the stomach, or provide food and nutrition to patients.

[0003] However, the gastric tube is a No. 14 gastric tube, and the feeding tube is a No. 10 feeding tube. The tube diameters are thick, and the patient feels strong discomfort. The two tubes are easy to separate when inserted, which is not conducive to the nurse's operation. Therefore, the prior art provides a double-lumen gastric tube, including a main body, on which an X-ray mark and a scale of insertion depth are provided; the inner cavity of the main body is divided into a main cavity and an auxiliary cavity by a diaphragm, and the side wall of the main cavity is provided with several side holes. The main cavity and the auxiliary cavity are connected inside the head of the main body to form a common cavity. However, when the two tubes are inserted, one tube may be in the stomach and the other in the trachea, and the mark on the gastric tube is not eye-catching, which is not conducive to observing the insertion length, wasting time, and causing the patient's nausea and discomfort to last longer.

[0004] Based on this, the utility model designs a double-lumen stomach tube for pancreatic surgery. Utility Model Content
