Background
At present, in the radio frequency treatment operation of sphincter relaxation (such as cardia sphincter relaxation and anal sphincter relaxation in gastroesophageal reflux disease), the balloon is required to be expanded and tightly attached to the esophageal wall after being inflated, so that the esophagus generates certain tension, and a radio frequency electrode needle on the balloon can penetrate into the sphincter muscle layer. It will be appreciated that excessive esophageal tension, i.e. excessive balloon dilation, will result in mucosal damage; when the tension of the esophagus is too low, i.e. the contact between the wall of the sacculus and the wall of the esophagus is not tight enough, the radio-frequency electrode needle cannot penetrate into the sphincter muscle layer or penetrates into the sphincter muscle layer too shallow, thereby affecting the treatment effect.
In order to make the balloon normally contact with the esophageal wall, the inflation amount of the balloon needs to be controlled. The common inflation modes are mainly the following two: the degree of resilience pressure of the syringe push rod is sensed by a doctor in the manual inflation process to judge, or a pressure release valve for fixing air pressure is arranged in an inflation air path. However, the first method completely depends on the sensory judgment of the doctor, has high experience requirements on the clinician, and cannot accurately control the inflation amount because the physiological structures of the esophagus of the patient are different and the tube diameters are different.

The invention provides a balloon inflation circuit which is applied to a balloon inflation device. The balloon inflation device can inflate the inflatable balloon to enable the inflatable balloon to be attached to the esophageal wall, so that the radio-frequency electrode needle attached to the balloon can be penetrated into the sphincter muscle layer.
Referring to FIG. 1, in one embodiment, the balloon inflation circuit includes an inflatable balloon 10, an air conduit 20, an inflator 30, a pressure detection module 40, and a microcontroller 50.
The power end of the inflator 30 is connected with a first power supply V1, the inflator 30 is connected with the inflatable balloon 10 through the air pipeline 20, the pressure detection module 40 is arranged on the air pipeline 20, the signal input end of the microcontroller 50 is connected with the pressure detection module 40, and the signal output end of the microcontroller 50 is connected with the inflator 30.
The inflator 30, when energized by a first power source V1, is capable of inflating the inflatable balloon 10 to expand the outer diameter of the inflatable balloon 10. The pressure detection module 40 can detect the air pressure in the air path pipe 20 during the inflation process of the inflator 30. It will be appreciated that the air passage conduit 20 is in communication with the inflatable balloon 10, and that the air pressure within the air passage conduit 20 is the same as the air pressure within the inflatable balloon 10. After the pressure detection module 40 detects the air pressure in the air channel 20, the air pressure may be converted into a pressure signal and the pressure signal may be sent to the microcontroller 50. The microcontroller 50 may send a start signal to the inflator 30 when a user triggers a start operation, so that the inflator 30 inflates the inflatable balloon 10, and during inflation, the microcontroller 50 may determine the current air pressure in the air path tube 20 according to the received pressure signal. In the process of expanding the inflatable balloon 10, the pressure in the inflatable balloon 10 and the air path pipeline 20 is also continuously increased, and when the inflatable balloon 10 is expanded to be in contact with the esophageal wall, the pressure of the inflatable balloon 10 is further increased due to the contact and extrusion of the esophageal wall, and the microcontroller 50 can determine the close contact condition of the inflatable balloon 10 and the esophageal wall according to the detected air pressure value. When the microcontroller 50 detects that the air pressure reaches the preset pressure threshold, indicating that the inflatable balloon 10 is attached to the esophageal wall at this time, the microcontroller 50 may send a stop signal to the inflator 30 to stop the inflator 30 from inflating the inflatable balloon 10. When the inflatable saccule 10 is tightly attached to the esophageal wall, the radio-frequency electrode needle attached to the inflatable saccule 10 can be punctured into the sphincter muscle layer to carry out radio-frequency treatment. During the treatment process, when the inflator 30 stops inflating, a slight air leakage will occur at the interface or gap of the air path tube 20, so that the air pressure in the air path tube 20 is reduced. At this time, the microcontroller 50 may also continuously detect the air pressure in the air path pipeline 20 through the pressure detection module 40, and when the microcontroller 50 detects that the air pressure is reduced to the low-pressure threshold value, the microcontroller 50 may send a start signal to the inflator 30, so that the inflator 30 is restarted to perform inflation compensation, so that the pressures in the inflatable balloon 10 and the air path pipeline 20 are always kept in a normal range interval, and the inflatable balloon 10 can be kept to be attached to the esophageal wall.
In this embodiment, the pressure detection module 40 is disposed in the air path conduit 20, so that the air pressure can be detected during the inflation process of the inflatable balloon 10, and the microcontroller 50 can determine whether the inflatable balloon 10 is attached to the esophageal wall according to the detected air pressure, and stop the inflation when the inflatable balloon 10 is attached to the esophageal wall. The microcontroller 50 may also continuously detect the air pressure in the air path conduit 20 after the inflatable balloon 10 is tightly attached to the esophageal wall, and control the inflator 30 to perform inflation compensation when the air pressure is reduced to a low pressure threshold value due to air leakage, so that the inflatable balloon 10 is always tightly attached to the esophageal wall in the treatment process.
It should be noted that the first power source V1 can provide a dc voltage of 5V, and the inflator 30 can operate normally after receiving the 5V power supply, and inflate the inflatable balloon 10 through the air conduit 20.
