When the anesthesia machine is needed to be used for anesthesia, an operator firstly electrifies the whole device, vaporized anesthetic in the anesthesia machine flows out of the instrument tube section 1 through the rotation of the turbine 101, meanwhile, the operator adjusts the flow of the anesthetic according to actual conditions, monitors the anesthetic flow in the instrument tube section 1 through the flow sensor 102, and because the temperature of the outside is lower, the anesthetic gas in the instrument tube section 1 is contracted, so that the gas flow output from the instrument tube section 1 is smaller than a preset value and the gas concentration is larger than the preset value, the gas in the instrument tube section 1 is heated at the moment, and finally the gas flow and the concentration output from the instrument tube section 1 are accordant with the preset value, and the two conditions are divided:
when the preset anesthetic flow is relatively large, the anesthetic flow input into the meter tube section 1 is large, the anesthetic gas in the meter tube section 1 is contracted due to the low-temperature environment, so that the gas flow output from the meter tube section 1 is smaller than the preset flow, the gas concentration output from the meter tube section 1 is larger than the preset concentration, the first temperature sensor 104 detects that the ambient temperature is lower, the heating tube 105 is controlled by the control module to heat, and when the flow sensor 102 detects the flow, the control module controls the small motor 108 to start, the output shaft of the small motor 108 rotates to drive the gear 109 to rotate, the fluted disc 106 rotates, the heating tube 105 and the rotary drum 103 are driven to rotate together, the heating tube 105 uniformly heats the meter tube section 1, the temperature of the meter tube section 1 is increased by heating, the gas in the meter tube section 1 is expanded, the anesthetic flow is increased, and the anesthetic concentration is further diluted to reach a standard state;
when the preset anesthetic flow is relatively smaller, the anesthetic flow input into the meter tube section 1 is smaller, if the heating tube 105 is close to the meter tube section 1, the temperature of the gas in the meter tube section 1 is too high, the anesthetic gas is excessively expanded, the gas flow is further excessively high, the concentration is excessively thin, and the output gas flow is higher than a preset value, in order to avoid the situation, when the flow sensor 102 detects that the anesthetic flow in the meter tube section 1 is smaller, the flow sensor 102 sends an electric signal to the microcontroller 110, the microcontroller 110 sends a signal to the signal receiver 111, the signal receiver 111 receives the signal, the telescopic end of the electric push rod 112 is controlled by the control module to be shortened, the push frame 113 is driven to move leftwards, the push frame 113 presses the heating tube 105 to move outwards, the first spring 107 is compressed, the heating tube 105 is moved outwards away from the meter tube section 1, and accordingly heating of the anesthetic in the meter tube section 1 is weakened, and accordingly the output gas flow and the concentration in the meter tube section 1 are enabled to be weakened according with the preset value.
After the anesthetic is transferred, the flow sensor 102 does not detect the flow, a signal is transmitted to the first temperature sensor 104 through the control module, then the control module controls the heating tube 105 to be closed, meanwhile controls the small motor 108 to be closed, and sends a signal to the microcontroller 110, so that the microcontroller 110 controls the expansion end of the electric push rod 112 to extend, the push frame 113 moves rightwards, the push frame 113 does not squeeze the heating tube 105 any more, and the first spring 107 resets to drive the heating tube 105 to reset.
