Large aperture barrel strainer 632 above crossing；When collection needs to take the sample of slightly larger parasitic protozoa or nematode larval, increase by first
The amount of buffer solution in storage sample container 11, makes it there not to be large aperture barrel strainer 632.
The effect of variation four and effect
The excrement sampling provided according to variation four and parasite concentration device, because barrel strainer contains large aperture tubbiness
Filter screen and small-bore barrel strainer, can meet the parasite to being relatively large in diameter or worm's ovum is sampled the requirement of inspection, and energy
Carry out the inspection by sampling of current conventional parasitic worm.
Variation five
Likewise, in this variation five, for identical structure in embodiment one, give identical symbol, and save
Omit identical explanation.
Figure 11 is the structural representation of resampling filter device in variation five of the invention.
As shown in figure 11, the barrel strainer 73 in resampling filter device 7 includes small-bore barrel strainer 731 and large aperture bucket
Shape filter screen 732, the filter opening of small-bore barrel strainer 731 is located at side wall and bottom, and the filter opening of large aperture barrel strainer 732 is located at greatly
The aperture of filter opening is 400 μm, large aperture barrel strainer 632 in the bottom of aperture barrel strainer 732, small-bore barrel strainer 631
The aperture of middle filter opening is 800 μm.
The application method of excrement sampling and parasite concentration device is similar with variation four in variation five, but variation is just before dawn
It is suitable for hyperbaric buffer solution or fixer, small-bore filter screen 731 and the bottom of large aperture barrel strainer 732 are respectively provided with filter opening,
So that the big worm's ovum of floating upward quickly passes through filter opening faster in the buffer solution or fixer.
The effect of variation five and effect
