Embodiment 3
The present embodiment 3 is the further advantageous modification made on embodiment 2 basis, and the part do not addressed for this embodiment 3 all can reference example 2.
As shown in Figure 5, a container 12 is configured with a gage probe 18, No. two containers 13 and is configured with No. two gage probes 19.Each gage probe can be selected can the sensor of working solution weight or volume in measuring vessel.
An above-mentioned pump 14 and No. two pumps 15 are configured with the central controller 20 that can control each pump operation state.A gage probe 18 is connected central controller 20 respectively with No. two gage probes 19.
In aforesaid way, also the feed pathway 1 between an above-mentioned pump 14 and liquid outlet 4 end can be provided with a pressure transducer 21, the liquid outlet channel 2 between No. two pumps 15 and liquid inlet 5 end be provided with No. two pressure transducers 22; A pressure transducer 21, No. two pressure transducers 22 connect central controller 20, respectively for realizing the dynamic monitoring of flushing liquor.
In the present embodiment 3, the roughly work process of endoscope is as follows:
When utilizing a pump 14 and No. two pumps 15 pairs of visual areas to provide the flushing of large discharge, central controller 20 obtains the original measurement value of liquid in one, No. two container 12,13 by one, No. two gage probe 18,19 simultaneously, be set as a0 and b0 respectively, and control a pump 14 and No. two pumps 15 bring into operation;
Subsequently by the variable of central controller 20 by liquid in one, No. two gage probe 18,19 Real-time Obtaining, one, No. two containers 12,13, be set as a1 and b1 respectively, and compare with each self-corresponding above-mentioned original measurement value and obtain changing value, be set as Δ a and Δ b respectively, that is: Δ a=a1-a0, Δ b=b1-b0.
