S231, presetting a fourth temperature threshold and a fifth temperature threshold, wherein the fourth temperature threshold is smaller than the fifth temperature threshold.
S232, comparing the gas temperature of the gas outlet 153 with the fourth temperature threshold and the fifth temperature threshold.
S233, if the gas temperature of the gas outlet 153 is greater than the fifth temperature threshold, the heating pipe 152 is controlled to stop heating, and the temperature warning information is output.
If the fourth temperature threshold is less than or equal to the fourth temperature threshold and the gas temperature at the gas outlet 153 is less than or equal to the fifth temperature threshold, the heating tube 152 is controlled to stop heating, and the output of the temperature warning information is not performed.
And S235, if the gas temperature of the gas outlet end 153 is smaller than the fourth temperature threshold, the heating pipe 152 is controlled to be started for heating so as to heat the gas of the gas outlet end 153.
For example, the fourth and fifth temperature thresholds may be 32 ° and 41 °, respectively. CO at the outlet end 153 2 The gas temperature was compared to 32 ° and 41 °.
If the CO of the air outlet end 153 2 If the gas temperature is greater than 41 DEG, the heating pipe 152 is controlled to stop heating to prevent CO 2 The gas temperature continues to rise and temperature early warning information is output to prompt medical staff to process in time.
If 32 DEG is less than or equal to CO of the air outlet end 153 2 The gas temperature is 41 DEG or less, the heating pipe 152 is controlled to stop heating to prevent CO 2 The gas temperature continues to rise, and the output of the temperature early warning information, namely the clearing of the temperature early warning information, is not performed. If the CO of the air outlet end 153 2 When the gas temperature is less than 32 DEG, the heating pipe 152 is controlled to start heating so as to heat the CO at the gas outlet end 153 2 The gas is heated.
It will be appreciated that the pneumoperitoneum machine 100 is capable of enabling CO at the gas outlet 153 2 The gas temperature is stabilized between 32 degrees and 41 degrees to meet the requirements of the intracavity operation, thereby being beneficial to the rehabilitation of patients and improving the operation efficiency.
Of course, for the above example, the fourth and fifth temperature thresholds may also be set to 32.5 ° and 41.5 °,33 ° and 42 °, 33.5 degrees, 42.5 degrees and the like, and can be specifically set according to the requirements of the endoluminal surgery.
