Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gastroesophageal sphincter control, in particular to a gasbag control type artificial food and gastric tube sphincter. BACKGROUND

[0002] When food enters the esophagus, it stimulates the mechanical receptors on the esophageal wall, which reflexively causes the lower sphincter to relax, allowing food to enter the stomach. After the bolus enters the stomach, the lower esophageal sphincter contracts, restoring its resting tone, which prevents gastric contents from refluxing into the esophagus.

[0003] Patients with esophagogastric junction adenocarcinoma and other diseases related to the esophagus and stomach often cannot eat normally due to the effects of the disease, and need to use a special liquid diet gastric tube for assisted eating. The uneven nutrition of food brought by this eating method cannot meet the nutritional needs of patients recovering.

[0004] The existing special patients cannot simulate the relaxation and contraction of the normal eating sphincter during eating, and the food is easily vomited due to reflux, which affects the recovery of the patient. Therefore, it does not meet the existing needs, and for this purpose, we propose a gasbag control type artificial food and gastric tube sphincter. UTILITY MODEL CONTENT

[0010] Preferably, the signal output module is also connected to a control button signal on the controller.

[0011] Preferably, the display screen is electrically connected to the signal output module.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the cooperation of an air pump and air bladders, allows the device to be remotely activated via a wireless remote control system using a controller and control buttons. The air pump draws gas from the storage tube and evenly delivers it to the three air bladders. The air bladders then rapidly expand as they are filled with gas, compressing the outer surface of the stomach and esophagus. This causes the inner side of the stomach and esophagus to be compressed, and the inner diameter of the compressed part gradually decreases as the air bladders expand. Subsequently, the air pump is activated to draw the air from inside the air bladders back into the storage tube. The gas inside the air bladders then moves out and rapidly contracts, reducing the compression on the outer surface of the stomach and esophagus. The inner diameter of the compressed part gradually increases as the air bladders contract until it returns to its original size. Thus, the stomach and esophagus, through the compression of the air bladders, simulates the expansion and contraction of the sphincter muscles during normal eating, thereby satisfying the need for eating.

[0028] Further, the signal output module is further signal-connected with a control button 10 arranged on the controller.

[0029] Further, the display screen is electrically connected with the signal output module

[0030] One end of the flexible ring 2 is provided with a connecting end part 3, the other end of the flexible ring 2 is provided with a connecting tail part 4, the outer surface of the connecting tail part 4 is provided with a sticking part, the inner surface of the connecting end part 3 is provided with a sticking part, and the inner surface of the connecting end part 3 and the outer surface of the connecting tail part 4 are connected with each other by the sticking parts.

[0031] Through the cooperation of the connecting end part 3 and the connecting tail part 4, the device can wrap the flexible ring 2 around the outer surface of the gastroesophageal 1, and make the connecting end part 3 close to the position of the connecting tail part 4, so that the gastroesophageal 1 is wrapped in the flexible ring 2, and the connecting end part 3 and the connecting tail part 4 are connected through the surface sticking part, and at the same time, the gastroesophageal 1 is slightly extruded by the air bag 8, so that the flexible ring 2 is fixed at the sphincter position of the gastroesophageal 1, avoiding the displacement of the flexible ring 2.

[0032] The outer surface of the flexible ring 2 is provided with two gas storage pipes 7, the two ends of the gas storage pipes 7 are fixedly installed with gas delivery pipes 6, the gas delivery pipes 6 are connected with the input end of the air pump 5, and the outer side of the air pump 5 is provided with an air pump power supply 12.

[0034] The device can be remotely controlled by the controller 9 and the control button 10 through a wireless remote control system to start the air pump 5 when in use, so that the air pump 5 sucks the gas in the gas storage pipe 7 and uniformly delivers it to the inside of the three air bags 8. At this time, the air bags 8 are rapidly inflated by the gas filling, and then the outer surface of the gastroesophageal 1 is extruded, so that the inside of the gastroesophageal 1 is extruded out of the compressed part 11, and the inner diameter of the compressed part 11 gradually decreases with the expansion of the air bag 8. Then start the air pump 5, so that the air pump 5 draws the air in the air bag 8 back to the inside of the gas storage pipe 7.

The patient usually cannot eat normally at this time. The flexible ring 2 can be wrapped around the outer surface of the gastroesophageal 1 by surgery, and the connecting end 3 is close to the position of the connecting tail 4, so that the gastroesophageal 1 is wrapped in the flexible ring 2, and the connecting end 3 and the connecting tail 4 are connected by the surface adhesive component, and at the same time, the air bag 8 slightly extrudes the outer surface of the gastroesophageal 1, so that the flexible ring 2 is fixed at the sphincter position of the gastroesophageal 1, avoiding displacement of the flexible ring 2;

[0036] When the patient needs to eat normally, the controller 9 and the control button 10 can remotely control the air pump 5 through a wireless remote control system to start the air pump 5, so that the air pump 5 sucks the gas in the gas storage pipe 7 and uniformly delivers it to the inside of the three air bags 8. At this time, the air bags 8 are rapidly inflated by the gas filling, and then the outer surface of the gastroesophageal 1 is extruded, so that the inside of the gastroesophageal 1 is extruded out of the compressed part 11, and the inner diameter of the compressed part 11 gradually decreases with the expansion of the air bag 8. Then start the air pump 5, so that the air pump 5 draws the air in the air bag 8 back to the inside of the gas storage pipe 7. At this time, the gas in the air bag 8 moves out and rapidly shrinks, thereby reducing the extrusion of the outer surface of the gastroesophageal 1. At this time, the inner diameter of the compressed part 11 will gradually increase with the contraction of the air bag 8 until it returns to normal, so that the gastroesophageal 1 is extruded by the air bag 8 to simulate the expansion and tightening of the sphincter during normal eating, thereby meeting the eating needs.
