The terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, a flowchart of an endoscope airtightness detection method includes the steps of:
s1, arranging a plurality of pressure detection points on the air passage of the endoscope body.
And S2, enabling the host to acquire the deviation between the real-time pressure value of each pressure detection point and the preset calibration pressure value, comparing the deviation with the pressure measurement accuracy absolute value of the corresponding pressure detection point, and outputting the air tightness state information of the mirror.
Specifically, in step S2, the preset calibration pressure value is a pressure value detected by the corresponding pressure detection point at a standard atmospheric pressure.

When the deviation is smaller than or equal to the absolute value of the pressure measurement precision of the corresponding pressure detection point, the host outputs the information that the mirror body has good air tightness.
According to the endoscope air tightness detection method, the real-time pressure values of all pressure detection points on the endoscope body are obtained through the host, the air tightness state of the endoscope body is judged after the deviation amount is compared with the absolute value of the pressure measurement precision, the real-time monitoring of the endoscope body air tightness is realized, the problems of time consumption, inaccuracy and the like during manual operation are solved, and the monitoring precision is improved.
