Balloon inflation circuit and device

Abstract

The invention discloses a balloon inflation circuit and device. The balloon inflation circuit comprises an inflation balloon, an air channel pipeline, an inflation pump, a pressure detection module and a microcontroller, wherein the power end of the inflation pump is connected with a first power source; the inflation pump is connected with the inflation balloon through the air channel pipeline; the pressure detection module is arranged on the air channel pipeline; and the microcontroller is connected with the pressure detection module and the inflation pump. According to the invention, the inflation pump inflates the inflation balloon so as to expand the outer diameter of the inflation balloon; the pressure detection module detects the air pressure in the air channel pipeline, converts theair pressure into a pressure signal and sends the pressure signal to the microcontroller; the microcontroller is used for sending a starting signal to the inflation pump and sending a stopping signalto the inflation pump when the air pressure reaches a preset pressure threshold value; and when the air pressure is reduced to a low-pressure threshold value, a starting signal is sent to the inflation pump. According to the invention, the inflation balloon can be automatically inflated, so the inflation balloon can be clung to the esophageal wall, and accurate inflation of the inflation ballooncan be realized without manual operation in the inflation process.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a balloon inflation circuit and device. Background technique [0002] At present, in the radiofrequency treatment of sphincter relaxation (such as cardiac sphincter relaxation and anal sphincter relaxation in gastroesophageal reflux disease), it is necessary to inflate the balloon to make the balloon expand and stick to the esophageal wall, so that the esophagus generates a certain tension. So that the radiofrequency electrode needle on the balloon can penetrate into the sphincter muscle layer. It is understandable that if the esophageal tension is too large, that is, when the balloon expands too much, it will cause mucosal damage; if the esophageal tension is too small, that is, the contact between the balloon wall and the esophageal wall is not close enough, the radio frequency electrode needle cannot be penetrated. The sphincter muscle layer or puncture into the muscle layer ...
