In the present invention, the cross-sectional area of the current limliting slot 113 is transversal less than the first, second, third, fourth air slot
Area.It makes air-flow when flowing through current limliting slot 113, since its cross-sectional area becomes smaller, forms it into vapour lock, so that current limliting slot
Pressure in 113 increases；It is vented since 300 period of air pump is evacuated, so that the interior pressure of current path has fluctuation, even if fluctuation
Very little, but very big interference can be brought to 204 signal of differential pressure pick-up, so in order to improve the signal-to-noise ratio of differential pressure pick-up 204,
It is that anesthetic gases monitoring modular 200 is accurate that vapour lock is formed in the pipeline detected in integrated gas path plate for differential pressure pick-up 204
The premise for controlling flow, which raises pressure difference value measured by differential pressure pick-up 204, convenient for the measurement of differential pressure pick-up 204,
After differential pressure pick-up 204 is acquired pressure difference value, air pump 300 will be driven according to the size of its pressure difference value, to adjust
Gas circulation in current path.
In the present invention, when second air slot 111 is connected to the first gas chamber 118, the second monitoring interface air inlet
It is additionally provided with a connectedness (not shown) between mouth 107 and the second monitoring interface gas outlet 106, the connectedness is (not shown) logical
It crosses and the second air slot 111 and the is realized to the short circuit for stating the second monitoring interface air inlet 107 and the second monitoring interface gas outlet 106
The connection of one gas chamber 118.As when not needing to use the second monitoring modular in use, second monitors interface gas outlet mouthful
106 and second monitoring interface air inlet 107 on can not access the second monitoring modular, when oxygen concentration monitoring modular does not access, make
The second monitoring interface gas outlet 106 is connected with the second monitoring interface air inlet 107 with connectedness (not shown)；And work as
It, will be on the second monitoring interface gas outlet mouthful 106 and the second monitoring interface air inlet 107 when needing to use other monitoring functions
The second monitoring modular with corresponding function can be accessed.
Since the cross-sectional area of the first gas chamber 118 is greater than the cross-sectional area of the current path, so that into the gas after gas chamber
Stream flow velocity more mitigates, therefore the gas chamber can play the role of buffer gas flow, to keep the waveform of output more steady beautiful；And
The output end of first gas chamber 118 can also be connected to the second gas chamber 119, the setting of the first gas chamber 118 the second monitoring interface into
Between port 107 and the input end of current limliting slot 113, the compartment which is connected by two is mutually constituted；Second gas chamber
119 are arranged between air pump first interface 108 and the outlet end of current limliting slot 113, second gas chamber 119 by four be connected every
Room is mutually constituted；In current path of the invention, the first gas chamber 118 or the second gas chamber 119 can be only set in order to save space,
First gas chamber 118 and the second gas chamber 119 can be set simultaneously at the both ends of current limliting slot 113 in order to guarantee better effect.
In the present invention, it is additionally provided on the integrated gas path plate respectively with the input end of the current limliting slot 113 and out
The the first differential pressure monitoring interface 115 and the second differential pressure monitoring interface 116 that mouth end is connected, the first, second differential pressure monitoring connect
Mouth 115,116 is connected with differential pressure pick-up 204.
