as shown in fig. 9 and 10, the pumping assembly further includes a flush delivery tube 540 and a reservoir; the pump body 510 is a liquid pump and is communicated with a liquid storage bin, and purified water or physiological saline is stored in the liquid storage bin; the flushing delivery pipe 540 communicates the valve body 520 with the inner space of the buffer hollow sphere 200;
During the process of extracting the effusion, the pump body 510 is controlled to operate to extract the liquid medium from the liquid storage bin and pump the liquid medium to the buffer hollow sphere 200 at specific intervals (preferably 20 to 30 seconds), and simultaneously the expansion and contraction conveying column 410 is controlled to expand so as to seal all the suction holes 110; at this time, the liquid medium enters the buffer hollow ball 200 and washes the suction pipe body, so that the accumulated liquid on the wall is reduced, and the liquid medium finally flows into the aspirator; after the flushing is continued for a few seconds, the progress of the flushing is stopped and the components are reset.
In the process of flushing, the expansion and contraction of the built-in elastic tube 350 are controlled to alternately extrude the mixture of water and effusion in the built-in elastic tube 350 so as to assist in flushing and dredging, and further the flushing effect is improved.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
