Description

Technical Field

[0001] The invention relates to the technical field of gastroesophageal sphincter control, in particular to an airbag-controlled artificial gastroesophageal sphincter. Background Art

[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 food bolus enters the stomach, the lower esophageal sphincter contracts and restores its resting tension, which prevents gastric contents from flowing back into the esophagus. Patients with gastroesophageal and stomach diseases such as esophageal junction adenocarcinoma are usually unable to eat normally due to the impact of the disease and need to use a special liquid feeding tube to assist in eating. However, the food provided by this eating method is not nutritionally balanced and cannot meet the nutritional needs of the patient's recovery.

[0003] Existing special patients are usually unable to simulate the relaxation and contraction of the sphincter during normal eating, and food is easily vomited out due to reflux, which in turn affects the patient's recovery; therefore, it does not meet the existing needs. We have proposed an airbag-controlled artificial esophageal sphincter. Summary of the invention

[0004] The purpose of the present invention is to provide an airbag-controlled artificial esophageal sphincter to solve the problems mentioned in the above background technology that special patients usually cannot simulate the relaxation and contraction of the sphincter during normal eating when eating, and food is easily vomited out due to reflux, thereby affecting the patient's recovery.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an airbag-controlled artificial esophageal sphincter, comprising an esophagus and a stomach bag, wherein the stomach bag is connected to the lower part of the esophagus, a flexible ring is movably installed at a position near the sphincter on the outer surface of the esophagus, three air bags are movably installed on the inner side of the flexible ring, three air pumps are fixedly installed on the outer surface of the flexible ring, the output ends of the air pumps are through-connected to the inside of the air bags, and the air bags press the surface of the esophagus toward the inside of the esophagus to form a pressure-receiving portion on the inner side of the esophagus.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention cooperates with the air pump and the air bag, so that when the device is in use, the air pump can be remotely controlled by the controller and the control button through the wireless remote control system to start the air pump, so that the air pump absorbs the gas inside the air storage tube and evenly transports it to the inside of the three air bags. At this time, the air bags are filled with gas and expand rapidly, thereby squeezing the outer surface of the stomach and esophagus, so that the inner side of the stomach and esophagus is squeezed out of the pressure part, and the inner diameter of the pressure part gradually decreases with the expansion of the air bag. Then the air pump is started to draw the air inside the air bag back to the inside of the air storage tube. At this time, the gas inside the air bag moves out and shrinks rapidly, thereby reducing the squeezing of the outer surface of the stomach and esophagus. At this time, the inner diameter of the pressure part will gradually increase with the contraction of the air bag until it is restored, so that the stomach and esophagus are squeezed by the air bag to simulate the expansion and tightening of the sphincter when people eat normally, thereby meeting the eating needs; 2. The present invention cooperates with the connecting end and the connecting tail so that the device can wrap the flexible ring around the outer surface of the gastroesophageal tube and make the connecting end close to the connecting tail so that the gastroesophageal tube is wrapped in the flexible ring, and the connecting end and the connecting tail are connected by the adhesive component on the surface. At the same time, the airbag slightly squeezes the outer surface of the gastroesophageal tube so that the flexible ring is fixed at the sphincter position on the outer surface of the gastroesophageal tube to avoid displacement of the flexible ring.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] See also Figures 1 to 3 An embodiment of the present invention is as follows: an airbag-controlled artificial esophageal sphincter comprises an esophagus 1 and a stomach bag 13, wherein the stomach bag 13 is connected to the lower part of the esophagus 1, a flexible ring 2 is movably mounted on the outer surface of the esophagus 1 near the sphincter, three air bags 8 are movably mounted on the inner side of the flexible ring 2, three air pumps 5 are fixedly mounted on the outer surface of the flexible ring 2, and the output ends of the air pumps 5 are connected to the inside of the air bags 8, and the air bags 8 press the surface of the esophagus 1 toward the inner side of the esophagus 1 to form a pressure portion 11 on the inner side of the esophagus 1.

[0019] The air pumps 5 are all equipped with a wireless remote control system, which is connected to the controller 9. A plurality of control buttons 10 are provided on the surface of the controller 9, which are connected to the air pumps 5 via the wireless remote control system.

[0020] Furthermore, the controller 9 is provided with a display screen for real-time observation of the pressure of each airbag 8 .

[0021] Furthermore, the controller is internally provided with a signal receiving module, a signal output module, and a data processing module; the signal receiving module is connected to the signal of the pressure sensor arranged inside the airbag, and the signal output module is connected to the start-stop sensor arranged on the air pump; one end of the data processing module is connected to the signal receiving module, and the other end is connected to the signal output module.

[0022] Furthermore, the signal input module is also signal-connected to the control button 10 disposed on the controller.

[0023] Furthermore, the display screen is electrically connected to the signal output module A connecting end portion 3 is provided at one end of the flexible ring 2, and a connecting tail portion 4 is provided at the other end of the flexible ring 2. An adhesive component is provided on the outer surface of the connecting tail portion 4, and an adhesive component is provided on the inner surface of the connecting end portion 3. The inner surface of the connecting end portion 3 and the outer surface of the connecting tail portion 4 are adhesively connected to each other through the adhesive component.

[0024] Through the cooperation of the connecting end 3 and the connecting tail 4, the device can wrap the flexible ring 2 around the outer surface of the gastroesophageal tube 1 and make the connecting end 3 close to the connecting tail 4, so that the gastroesophageal tube 1 is wrapped in the flexible ring 2, and the connecting end 3 and the connecting tail 4 are connected by the adhesive parts on the surface. At the same time, the airbag 8 slightly squeezes the outer surface of the gastroesophageal tube 1, so that the flexible ring 2 is fixed at the sphincter position on the outer surface of the gastroesophageal tube 1 to avoid displacement of the flexible ring 2.

[0025] Two air storage pipes 7 are provided on the outer surface of the flexible ring 2 , and air delivery pipes 6 are fixedly installed at both ends of the air storage pipes 7 . The air delivery pipes 6 are connected to the input ends of the air pump 5 , and an air pump power supply 12 is provided on the outside of the air pump 5 .

[0026] The gas storage tube 7 is filled with filling gas, and the filling gas is transmitted to the inside of the airbag 8 through the air pump 5 and the air delivery pipe 6 .

[0027] Through the cooperation of the air pump 5 and the air bag 8, when the device is in use, the air pump 5 can be remotely controlled by the controller 9 and the control button 10 through the wireless remote control system to start the air pump 5, so that the air pump 5 absorbs the gas inside the air storage tube 7 and evenly transports it to the inside of the three air bags 8. At this time, the air bags 8 are filled with gas and expand rapidly, thereby squeezing the outer surface of the gastroesophageal 1, so that the inner side of the gastroesophageal 1 is squeezed out of the pressure-receiving portion 11, and the inner diameter of the pressure-receiving portion 11 gradually decreases with the expansion of the air bag 8. Then the air pump 5 is started to make the air pump 5 draw the air inside the air bag 8 back to the inside of the gas storage tube 7. At this time, the gas inside the air bag 8 moves out and shrinks rapidly, thereby reducing the squeezing of the outer surface of the gastroesophageal 1. At this time, the inner diameter of the pressure-receiving portion 11 will gradually increase with the shrinkage of the air bag 8 until it is restored, so that the gastroesophageal 1 is squeezed by the air bag 8 to simulate the expansion and tightening of the sphincter during normal eating, thereby meeting the eating needs.

[0028] When the airbag-controlled artificial esophageal sphincter is in use, when the patient suffers from a disease related to the esophagus 1 or the stomach, the patient is usually unable to eat normally. At this time, the flexible ring 2 can be wound around the outer surface of the esophagus 1 through surgery, and the connecting end 3 is close to the connecting tail 4, so that the esophagus 1 is wrapped in the flexible ring 2, and the connecting end 3 and the connecting tail 4 are connected through the adhesive component on the surface, and at the same time, the airbag 8 slightly squeezes the outer surface of the esophagus 1, so that the flexible ring 2 is fixed at the sphincter position on the outer surface of the esophagus 1 to avoid displacement of the flexible ring 2; Then, when the patient needs to eat normally, the air pump 5 can be remotely controlled by the controller 9 and the control button 10 through the wireless remote control system to start the air pump 5, so that the air pump 5 absorbs the gas inside the air storage tube 7 and evenly transports it to the inside of the three air bags 8. At this time, the air bags 8 are filled with gas and expand rapidly, thereby squeezing the outer surface of the gastroesophageal 1, so that the inner side of the gastroesophageal 1 is squeezed out of the pressure-receiving portion 11, and the inner diameter of the pressure-receiving portion 11 gradually decreases with the expansion of the air bag 8. Then, the air pump 5 is started to make the air pump 5 draw the air inside the air bag 8 back to the inside of the gas storage tube 7. At this time, the gas inside the air bag 8 moves out and shrinks rapidly, thereby reducing the squeezing of the outer surface of the gastroesophageal 1. At this time, the inner diameter of the pressure-receiving portion 11 will gradually increase with the contraction of the air bag 8 until it is restored. Then, the expansion and contraction of the air bag 8 are repeated, so that the gastroesophageal 1 is squeezed by the air bag 8 to simulate the expansion and tightening of the sphincter of the gastroesophageal 1 when a person eats normally, thereby meeting the eating needs.
