Embodiment 1
[0052] figure 1 It is a partial cross-sectional view of the three-dimensional structure of the biological sample dividing machine in Embodiment 1 of the present invention, figure 2 It is a cross-sectional view of a biological sample dividing machine according to Embodiment 1 of the present invention, such as figure 1 and figure 2 As shown, the biological sample dividing machine 100 according to Embodiment 1 of the present invention includes a dividing mesh body 110 , a rotating stage 120 , a rotating driving device 130 , a collector 140 , an air injection device 150 and a liquid injection device 160 . The segmented mesh body 110 surrounds an accommodating space 111 , and a first opening 112 and a second opening 113 located on opposite sides of the accommodating space 111 and communicating with the accommodating space 111 . In Embodiment 1 of the present invention, the segmented mesh body 110 is a hollow columnar structure with two sides open, but it is not limited thereto....
Embodiment 2
[0064] image 3 It is a sectional view of a biological sample dividing machine according to Embodiment 2 of the present invention, such as image 3 As shown, the second embodiment of the present invention is similar to the first embodiment, and only the differences will be described below, and the similarities will not be repeated here.
[0065] In the biological sample dividing machine 200 according to the second embodiment of the present invention, the carrying surface 221 of the rotary stage 220 has a plurality of protruding structures 2211 . A plurality of protruding structures 2211 can increase the frictional force between the biological sample S and the bearing surface 221, prolong the time for the biological sample S to rotate with the bearing surface 221, so that when the biological sample S leaves the bearing surface 221, it can bear a large centrifugal force and has Greater speed. In this way, a better cutting effect can be obtained when the biological sample S col...
Embodiment 3
[0067] Figure 4 It is a cross-sectional view of the biological sample dividing machine according to the third embodiment of the present invention, such as Figure 4 As shown, the third embodiment of the present invention is similar to the first embodiment, and only the differences will be described below, and the similarities will not be repeated here.
[0068] In the biological sample divider 300 according to the third embodiment of the present invention, the thickness of the central area of the rotating stage 320 is smaller than that of the edge area, so that the carrying surface 321 is disc-shaped. The disc-shaped bearing surface 321 makes the centrifugal force only have the component force directed from the central area of the rotating stage 320 to the edge area, which can drive the biological sample S to move away from the bearing surface, prolonging the time for the biological sample S to rotate with the bearing surface 321 , so that the biological sample S has a g...
