It should be emphasized that, the process obtains two parameters of the actual pH value and the actual pressure value at the same time, and compares the actual pH value with the preset pH value to determine whether there is a gastric acid regurgitation condition, if the actual pH value is greater than or equal to the preset pH value, there is no gastric acid regurgitation condition, and the air bag 5 should not block the gastric-esophageal duct 4, so the deflation and contraction of the air bag 5 are executed and controlled in step S42; and comparing the actual pressure value with the preset pressure value to determine whether the balloon 5 is already in an expanded state or whether the gastroesophageal duct 4 allows the balloon 5 to be blocked in an inflation and expansion manner, wherein if the actual pressure value is greater than or equal to the preset pressure value, the balloon 5 is already in the expanded state or the air pressure condition in the gastroesophageal duct 4 does not allow the balloon 5 to be blocked in the inflation and expansion manner, and therefore, the deflation and contraction of the balloon 5 are executed and controlled in step S42.
For better technical effect, the method further comprises the following step after step S41: alarming and recording the ill information of the patient, and uploading the ill information to a medical network in real time. The illness information comprises personal information, illness time, treatment time and the like of the patient, and also comprises information of pH value of gastric acid before and after obstruction of the patient. The medical network can be an internal local area network built by the medical institution and can also be an external internet used by the medical institution.
In a specific embodiment, step S10 specifically includes: and setting a preset pH value and a preset pressure value, and acquiring and visually monitoring the actual pH value of gastric acid in the gastroesophageal tract 4 and the actual pressure value of air in the air bag 5 in real time. The preset pH value is set according to the general cognition of the medical field on the acid regurgitation, can be different from person to person and is customized individually for different patients. The preset pressure value should be set in conjunction with the relevant state parameters of the airbag 5. The visual monitoring can display the actual pH value, the actual pressure value, and the preset pH value and the preset pressure value preset in advance on a screen or other equipment in real time.
In a specific embodiment, step S41 specifically includes: the pneumatic pump is controlled to be started, the air bag 5 is inflated, and the air bag 5 is expanded to block the gastroesophageal duct 4. The air pressure pump can be arranged in the air bag 5 or externally arranged in the air bag 5, the air pressure pump flushes outside air into the air bag 5 to inflate the air bag 5, and the inflated air bag 5 obstructs the gastroesophageal tract tube 4 to prevent the regurgitation of gastric acid.
On the basis, step S10 is repeated after step S41, in other words, after the condition of the patient is relieved by the blockage, step S10 is repeated to obtain the actual pH value and the actual pressure value again, and if the actual pH value is no longer less than the preset pH value after the condition of the patient is relieved to a certain extent, the patient does not need to take measures to block the acid regurgitation, and step S42 is performed. In addition, step S10 is repeated after step S42, and if the patient 'S condition has a delay or the first detection is inaccurate, the actual pH and pressure values are obtained again to diagnose the patient' S condition.
