Problems solved by technology

[0005] However, this kind of filter membrane is molded together with the film-making chamber, so when in use, the sample density separation liquid enters from the upper end of the film-making chamber and flows through the filter membrane to the top of the glass slide, so that a part of the sample density separation liquid sticks to the filter membrane In addition, it hinders the entry of the cell preservation solution, and during use, due to the setting of the filter membrane, the space pressure formed between the filter membrane and the glass slide may be greater than the external pressure, which will also prevent the cell protection solution from passing through the filter. membrane

Embodiment 1

[0039] Example 1: Such as figure 1 , A cell smear device, comprising a slide making bin base 1, a slide 2 located above the slide making bin base 1, and a slide making bin 3 fixed on the slide 2.

[0040] Such as figure 2 As shown, the machine base of the film silo 3 is a rectangular parallelepiped as a whole, a semicircular through slot 11 is opened on one side of the base 1 of the film silo, a mounting groove 12 is opened above the machine base of the film silo 3, and the slide 2 is placed in the installation In the slot 12; both sides of the film production bin base 1 are fixed with clamping blocks 13, and the two clamping blocks 13 are provided with clamping slots 14 on opposite sides, and the two clamping slots 14 extend along the length direction of the film making bin base 1 , The height of one of the grooves 14 is gradually lowered from one end to the other end, and the other groove 14 is just opposite to the direction in which the height of the groove 14 becomes shallow....

Embodiment 2

[0046] Example 2: A glass cell smear, such as Picture 9 The difference from Embodiment 1 is that: the filter cup 4 is not provided with abutting strips 43, and the outer wall of the filter cup 4 is spaced apart from the inner wall of the chip making chamber 3.

Embodiment 3

[0047] Example 3: A glass cell smear device, such as Picture 10 The difference from Embodiment 1 is that: the outer wall of the abutting strip 43 all abuts the inner wall of the filming bin 3.

Abstract

The invention provides a cell smearing device. The cell smearing device comprises a smear preparation bin, a glass slide and a smear preparation bin base, wherein a filter cup is arranged in the smear preparation bin, an annular flange is arranged at the upper end of the filter cup and is abutted against the upper end surface of the smear preparation bin, a filter screen is fixed at the lower end of the filter cup, and a cytoprotective solution enters and penetrates the filter screen conveniently.

Description

Technical field [0001] The invention relates to a cell smear device. Background technique [0002] The cell smear is mainly used to observe the internal structure of the cell and to determine whether the cell has a disease. [0003] The cells to be smeared are generally located in the preservation solution, which contains other impurities in addition to the cells, so impurity removal work is required before smearing. [0004] In order to solve the above problems, the Chinese patent with publication number CN201413266 discloses a cell smear device, which includes a slide chamber, a glass slide, the slide chamber is matched with the slide glass, and also includes a pallet and an integrated with the slide chamber Formed base of the film making chamber, the slides are placed on the pallet, two opposite inner side walls of the base of the film making chamber are provided with slots corresponding to the pallet, and both ends of the pallet are horizontally placed in the slots The lower no...
