[0002] The triple-lumen gastric tube is a medical device product that is improved and upgraded on the traditional single-lumen gastric tube. It is inserted through the nostrils, passes through the pharynx, and reaches the stomach through the esophagus. One-time placement of the tube can solve the problems of gastrointestinal flushing, nutrition, and decompression, avoid the damage caused by repeated placement of traditional gastric tubes, avoid cross infection, and reduce patient pain. It is one of the common medical devices in extracorporeal circulation and cardiac surgery.

[0003] The existing double-capsule three-chamber hemostatic gastric tube has the following disadvantages when in use: the end of the existing double-capsule three-chamber hemostatic gastric tube is provided with an end tube and a side hole structure for extracting gastric juice from the user's stomach. The existing end tube structure is an ordinary tube body structure, which is easy to adhere to the stomach wall and damage the stomach during negative pressure suction operation. At the same time, gastric juice is easy to block the extraction hole, affecting the normal extraction of gastric juice. For this reason, we propose a double-capsule three-chamber hemostatic gastric tube. Utility Model Content

[0007] Furthermore, a stomach bag inflation tube and an esophageal bag inflation tube are installed at one end of the stomach tube away from the end tube, and both the stomach bag inflation tube and the esophageal bag inflation tube are installed with a one-way valve inside; the stomach bag and the esophageal bag are controlled by the one-way valve to prevent gas backflow and improve the reliability of clinical tube placement.

[0008] Furthermore, a connecting tube is provided at one end of the stomach tube away from the end tube; the end of the connecting tube has a reduced diameter to facilitate docking and the addition of connecting accessories, thereby performing a gastric juice extraction operation.

[0009] Furthermore, a side tube is integrally formed on the side of the connecting tube and the wire drawing end passes through the inside of the side tube, and the wire drawing end is installed with an end ring located at the end of the side tube; the side tube structure is used to facilitate wire drawing, and the end ring structure limits the position of the wire drawing end.

[0010] Furthermore, inflation tube protective caps are installed at the ends of the stomach balloon inflation tube and the esophageal balloon inflation tube; the inflation tube protective cap structure can protect the stomach balloon inflation tube and the esophageal balloon inflation tube.

[0011] Compared with the prior art, the utility model has the following beneficial effects: a stomach bag, an esophageal bag and an end tube are arranged on one side of the stomach tube, and an arc-shaped convex piece is arranged at a position corresponding to the side hole on the outer periphery of the end tube. The arc-shaped convex piece is kept in an outwardly supported state and has a certain elasticity under the action of the arc-shaped metal wire inside the end tube. The arc-shaped convex piece is compressed during insertion, and the arc-shaped convex piece is stretched open after entering the stomach, and the stomach tube is used to extract gastric juice. During the extraction process, the arc-shaped convex piece supports the outer periphery of the end tube to prevent the stomach wall from directly entering the side hole during negative pressure adsorption, thereby protecting the patient's stomach. At the same time, if the side hole is blocked during the adsorption process, the wire can be pulled outward, and the arc-shaped convex piece can be deformed by the connecting wire, and the convex ring structure is inserted into the side hole to realize the dredging of the side hole, which is convenient and quick, improves the safety and convenience of operation, and is particularly suitable for extracorporeal circulation and cardiac surgery; the stomach bag and the esophageal bag are controlled by a one-way valve to prevent gas backflow and improve the reliability of clinical catheterization.
