Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
As shown in Figures 1 to 4, a kind of filter master suitable for the automatic production facility of liquid basal cell of the utility model
It include: filter upper casing 1, filter screen 2, filter membrane 3, filter lower casing 4, glass slide 5, vacuum pump 6, vacuum tube 7, sewer pipe
8, waste liquid bottle 9, liquid storage chamber 10, sponge 11, the first positive stop lug boss 12, the second positive stop lug boss 13, anti-skidding boss 14, limiting groove
15, upper and lower liquid level line 16, third positive stop lug boss 17, filter screen installation base 18.
As shown in Figures 2 and 3, multiple anti-skidding boss 14 are evenly distributed on 1 outer wall upper end of filter upper casing, prevent on filter
Shell 1 slides.
1 outer wall middle position of shell on the filter is arranged in upper and lower liquid level line 16, is used to indicate the position of sample base fluid.
Multiple third positive stop lug boss 17 are evenly distributed on 1 outer wall lower end of filter upper casing, for the limit to filter upper casing 1
Position effect.
1 inner upper end of shell is arranged to liquid storage chamber 10 on the filter, is used for storage of specimens base fluid.
1 inner wall middle position of shell on the filter is arranged in filter screen installation base 18, for installing filter screen 2.
Filter screen 2 is mounted on filter screen installation base 18.Filter screen 2 is used to filter the impurity in sample base fluid.
1 inner wall lower end of shell on the filter is arranged in multiple limiting grooves 15.
As shown in Figure 2 and Figure 4, multiple first positive stop lug boss 12 are evenly distributed on 4 outer wall lower end of filter lower casing, for pair
The position-limiting action of filter lower casing 4.
Multiple second positive stop lug boss 13 are evenly distributed on 4 outer wall of filter lower casing and close to 12 upper ends of the first positive stop lug boss
Setting.The quantity of second positive stop lug boss 13 is preferably identical as the quantity of limiting groove 15.
The setting of sponge 11 is arranged in 4 inner upper end of filter lower casing, filter membrane 3 in 4 inner upper end of filter lower casing, and
Filter membrane 3 is located at 11 upper end of sponge.Filter membrane 3 uses a kind of biological nano filter membrane, is used for filtration cell.Sponge 11 for pair
Filter membrane 3 is played a supporting role, while being filtered effect to sample base fluid waste liquid.
It is waste liquid chamber inside filter lower casing 4, is used for storage of specimens base fluid waste liquid.
As depicted in figs. 1 and 2, filter lower casing 4 is inserted into inside filter upper casing 1, the on 4 outer wall of filter lower casing
Two positive stop lug boss 13 are embedded in the limiting groove 15 on 1 inner wall of filter upper casing, pass through the second positive stop lug boss 13 and limiting groove
The connection of filter lower casing 4 and filter upper casing 1 is realized in 15 cooperation.
As shown in Figure 1, waste liquid bottle 9 is placed near filter lower casing 4 and filter upper casing 1,8 one end of sewer pipe and mistake
The waste liquid chamber of filter lower casing 4 is connected, and the other end is inserted into waste liquid bottle 9.7 one end of vacuum tube is connected with waste liquid bottle 9, the other end
It is connected with vacuum pump 6.
In use, the filter of the utility model is mounted in the automatic production facility of liquid basal cell, sample base fluid bottle is taken
Rock in the hand it is several under, be uniformly distributed a bottle inner cell, then slowly to liquid storage chamber 10 pouring into sample base fluid, (sample base fluid includes
Cell and cell keep liquid, and the amount for generally pouring into sample base fluid is 2.5-3 milliliters, not more than upper in liquid level line 16 up and down
Liquid level line), start vacuum pump 7, the work of vacuum pump 7 makes to form vacuum in waste liquid bottle 9, while making the waste liquid chamber of filter lower casing 4
Negative pressure is generated, sample base fluid is flowed down since suction function passes through filter screen 2, and filter screen 2 can filter out larger particles impurity, prevent
Only it influences next step film-making；It is special due to filter membrane 3 when sample base fluid passes through the filter membrane 3 of 4 upper end of filter lower casing
Property make cell in sample base fluid keep the waste liquid chamber that liquid passes through filter membrane 3 and sponge 11 flows into filter lower casing 4, and
Cell is isolated in 3 upper surface of filter membrane, and after cell keeps liquid to separate with cell, cell keeps liquid to become waste liquid and flows into waste liquid
Chamber is easily polluted the environment, should be dealt carefully with to waste liquid since cell keeps liquid to have certain corrosivity, therefore,
Waste liquid enters waste liquid bottle 9 by sewer pipe 8 under the action of negative pressure, at this point, cell has stayed on filter membrane 3, then such as Fig. 1 institute
Show, mobile filter lower casing 4 is by position A to position B, and mobile glass slide 5 is by position C to position D, at this point, 5 lower surface of glass slide
Glass slide 5 is then moved by position D by the cell adherence of 3 upper surface of filter membrane on glass slide 5 in 3 upper surface of contact filtration film
Glass slide 5 is taken out to position C, mobile filter lower casing 4 makes filter lower casing 4 and 1 group of filter upper casing by position B to position A
It is fitted together, thus complete a film-making circulation.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
