[0001] The utility model relates to the technical field of medical instruments, in particular to a gourd-shaped barium powder liquid sac nasogastric tube for preventing reflux of the cardia. Background Art

[0002] A nasogastric tube is a medical device inserted through the nose to deliver nutrients or medications to the gastrointestinal tract;

[0003] (1) For example, a gastrointestinal nutrient tube for preventing reflux and displacement, with a national patent publication number of CN205181968U, comprises a nutrient tube, an interface connected to the front end of the nutrient tube, and a balloon sleeved on the rear end of the nutrient tube; the two ends of the balloon are fixed to the outer wall of the rear end of the nutrient tube, and the inflatable part of the balloon is between the two ends of the balloon; the nutrient tube is a double-lumen structure, one of the lumens is a nutrient solution injection channel, and the other lumen is a balloon filling channel; the part of the rear end of the nutrient tube that is not sleeved with the balloon is provided with a side hole.

[0004] (2) For example, a gastric tube for patients undergoing gastrointestinal surgery with a national patent publication number of CN206045157U comprises a gastric tube body, an air bag, an inflation device and a suction device, wherein the air bag comprises an upper air bag and a lower air bag, and the inflation device comprises an upper air bag inflation device and a lower air bag inflation device, wherein the upper air bag and the lower air bag are respectively arranged above and below the gastric tube body and are located below the lower air bag, and a plurality of side holes are arranged on the gastric tube body, and the gastric tube body is respectively connected with the upper air bag inflation device, the lower air bag inflation device and the suction device; the bottom end of the gastric tube body is closed and hemispherical; a plurality of the side holes are arranged on different circumferences of the gastric tube body and are staggered; the maximum diameter of the upper air bag is smaller than the maximum diameter of the lower air bag.

[0005] (3) For example, a novel esophageal dilatation balloon catheter with a national patent publication number of CN213048922U comprises an esophageal dilatation balloon (11) at the upper end, an anti-reflux balloon (12) at the lower end, a central nasogastric tube (13), a guide wire in the central catheter (14) and a water injection interface with a valve at the tail end (15), wherein the esophageal dilatation balloon (11) is located at the upper end of the novel dilatation balloon and is placed at the esophageal stenosis in the esophagus, the anti-reflux balloon (12) is located at the lower end of the novel dilatation balloon and is placed at the gastric cardia, the central nasogastric tube (13) is located at the center of the novel esophageal dilatation balloon catheter (1) and is hollow, and the water injection interface with a valve at the tail end (15) is located at the tail end of the novel esophageal dilatation balloon catheter (1), and the dilatation pressure of the esophageal dilatation balloon (11) and the anti-reflux balloon (12) are adjusted by controlling the water injection volume.

[0006] (4) For example, the national patent publication number CN220293902U is an esophageal blocking device for preventing reflux, comprising a gastrointestinal decompression drainage tube body that is inserted into the esophagus of a patient to prevent reflux and aspiration when medical personnel perform relevant operations on the patient, a front end decompression hole is provided at the front end of the gastrointestinal decompression drainage tube body, and a rear end suction hole is provided at the rear end of the gastrointestinal decompression drainage tube body; a cuff structure that can effectively block the esophagus of the patient when medical personnel perform relevant operations on the patient, and the cuff structure is arranged on the gastrointestinal decompression drainage tube body and is located near the front end thereof.

[0007] After use, it was found that:

[0008] The gastrointestinal nutrition tube and balloon catheter in (1) and (3) above can only be used to deliver nutrient solution, and cannot perform gastric fluid aspiration and balance the intragastric pressure. The functions are relatively simple. In addition, the double balloon structure arranged above and below in (3) will increase the patient's discomfort when the tube is inserted into the esophagus or stomach due to the double balloon structure.

[0009] Although the gastric tube in (2) above is provided with a suction device, it is necessary to balance the intragastric pressure during suction to avoid stomach discomfort, and the gastric tube in (2) does not have a facility for balancing the intragastric pressure during suction;

[0010] In the esophageal blocking device for preventing reflux in (4), although the tail suction hole 120 and the front pressure relief hole 110 for sucking gastric juice are disclosed, the front pressure relief hole 110 is arranged at the rear end of the cuff 210, that is, when the cuff 210 is in an expanded state, the front pressure relief hole 110 can only balance the intragastric pressure at the rear end of the cuff 210, but cannot balance the intragastric pressure at the front end of the cuff 210. Most importantly, the esophageal blocking device for preventing reflux in (4) only blocks the esophagus of the patient during surgery through the cuff, but does not have the function of feeding nutrient solution.

[0011] Therefore, when nutrient solution infusion is required, and a nasogastric tube with cardia anti-reflux function and intragastric pressure balancing function is required, the above four products need further improvement to meet the usage requirements. Utility Model Content
