the anesthetic machine is characterized in that high-pressure gas (air, oxygen, laughing gas and the like) is firstly depressurized through a depressurization valve to obtain low-pressure and stable gas, then the low-pressure and stable gas is regulated by a flowmeter and an oxygen-laughing gas proportion regulating device to generate mixed gas with certain flow and proportion, the mixed gas enters a breathing pipeline, anesthetic medicaments generate anesthetic vapor through a volatilizing pot, the anesthetic vapor with required quantity is controlled to enter the breathing circuit, the mixed gas is conveyed to an operator along with the mixed gas, the mixed gas containing the anesthetic vapor is sucked into the lung by suction negative pressure generated when a human body sucks the air, and the mixed gas is conveyed to each organ of the human body through blood circulation, so that the organs temporarily lose consciousness and various reflections in a certain time, and the anesthetic purpose is achieved;

the safety of the anesthetic device mainly depends on the regulation and control of anesthetic concentration, in the actual use process of the anesthetic device, factors influencing anesthetic output concentration are many, such as the temperature of an evaporation chamber, as anesthetic can take away some heat of the evaporation chamber in the volatilization and output processes, the temperature in the evaporation chamber is reduced, so that the required volatilization rate of liquid anesthetic in the evaporation chamber is suddenly reduced, the output anesthetic concentration is lower, if the air pressure in the evaporation chamber is changed, the output of anesthetic is seriously influenced, if the air pressure in the evaporation chamber is changed, the high output anesthetic concentration of the air pressure in the evaporation chamber is high, if the air pressure in the evaporation chamber is low, otherwise, if the liquid level of liquid anesthetic in the evaporation chamber is high, the higher the liquid level is, the effective contact area of carrier gas and the liquid level is larger, and the anesthetic evaporates faster;

The working principle and the beneficial effects of the technical scheme are as follows: when the carrier gas takes away a part of anesthetic vapor through the evaporation chamber 200, the temperature in the evaporation chamber 200 also decreases, the output concentration of the anesthetic vapor is unstable due to the fluctuation of the temperature in the evaporation chamber 200, the life of a patient is endangered in severe cases, when the temperature in the evaporation chamber 200 decreases to a preset temperature, that is, the actual detection value of the evaporation chamber temperature sensor 2045 is lower than the preset detection value, the heater 2043 starts to flow the heated circulating liquid along the temperature compensation hose 2044, thereby avoiding the rapid decrease of the temperature in the evaporation chamber 200, and when the temperature in the evaporation chamber 200 increases to 2-5 degrees below the preset temperature, the heater 2043 stops heating;

Because the carrier gas and the anesthetic gas circulate, the air pressure in the evaporation chamber 200 can change continuously, the concentration of the anesthetic drug output by the evaporation chamber 200 can be influenced by the air pressure change, so that the concentration of the anesthetic drug is difficult to control, when the air pressure in the evaporation chamber 200 is lower than the preset air pressure, or the input circuit 201 can not provide the carrier gas in time due to blockage or other reasons, namely, the actual detection value of the air pressure sensor 2064 is lower than the preset detection value, the air pressure adjusting compensation component is started, the communication switch 2063 is opened, the carrier gas in the air storage tank 2062 enters the evaporation chamber 200 through the U-shaped ventilation pipeline 2052, and the anesthetic drug steam in the evaporation chamber 200 is driven to flow into the bypass 203;

when the air pressure in the evaporation chamber 200 is higher than the preset air pressure, that is, when the actual detection value of the air pressure sensor 2064 is higher than the preset detection value, the first driving member drives the first meshing gear 2058 to slide along the first rotating shaft 2057, so that the first meshing gear 2058 and the second meshing gear 2059 are meshed with each other, then the dual-shaft output motor 2056 drives the first rotating shaft 2057 to rotate, the first rotating shaft 2057 rotates to drive the first meshing gear 2058 to rotate, the first meshing gear 2058 rotates to drive the second meshing gear 2059 to rotate, the second meshing gear 2059 rotates to drive the negative pressure fan 208 to rotate, the negative pressure fan 208 rotates to reduce the air pressure in the negative pressure installation cavity 2055, and at this time, the carrier gas and anesthetic gas in the evaporation chamber 200 are pressed into the U-shaped ventilation tube 2052 under the action of the air pressure and enter the negative pressure installation cavity 2055 through the ventilation tube 2060, so that the air pressure in the evaporation chamber 200 is reduced to the preset air pressure, and the ventilation tube 2060 can be adjusted to a proper opening degree by adjusting the flow adjusting switch 2061.

The working principle and the beneficial effects of the technical scheme are as follows: the change of the liquid level of the volatile anesthetic in the evaporation chamber housing 2042 also affects the output concentration of the anesthetic, when the actual detection value of the liquid level sensor 2080 is lower than the preset detection value, the liquid level of the volatile anesthetic is lower, the liquid level adjustment compensation driving assembly drives the stirring slurry 2049 to rotate, the stirring slurry 2049 rotates to drive the communication plate 2046 to rotate, the communication plate 2046 rotates to align the first through hole 2047 with the second through hole 2048, then the liquid level adjustment compensation driving assembly drives the liquid level compensation lead screw 2050 to rotate, the liquid level compensation lead screw 2050 rotates to drive the liquid level compensation piston 2051 to move upwards to squeeze the liquid level compensation cavity 205, and therefore the volatile anesthetic in the liquid level compensation cavity 205 enters the evaporation chamber housing 2042 through the first through hole 2047 and the second through hole 2048, and the liquid level of the volatile anesthetic in the evaporation chamber housing 2042 rises to the preset height;

when the actual detection value of the liquid level sensor 2080 is higher than the preset detection value, and the liquid level of the instant anesthetic is higher, the liquid level adjustment compensation driving assembly drives the liquid level compensation screw 2050 to reversely rotate, and the liquid level compensation screw 2050 reversely rotates to drive the liquid level compensation piston 2051 to downwards move along the extrusion liquid level compensation cavity 205, so that the volatile anesthetic in the evaporation chamber housing 2042 is sucked into the liquid level compensation cavity 205, and the liquid level of the volatile anesthetic in the evaporation chamber housing 2042 tends to the preset liquid level;

When a rapid and large increase in the concentration of the volatile anesthetic is desired, the fluid level compensating piston 2051 is immobilized or pushed upward, and the fluid level adjusting compensating drive assembly drives the agitator paddle 2049 to rotate to accelerate the flow of the volatile anesthetic between the fluids.
