Description

A kind of chromosome sample dropping device

technical field

The utility model relates to an instrument for preparing chromosome samples, which belongs to the field of medical experiment and medical diagnosis.

Background technique

In the process of chromosome karyotype analysis, the staining quality of the chromosome specimen directly affects the result analysis. In the staining process, dropping slides is a very important link, which directly affects the success or failure of chromosome karyotype analysis. The existing technique for preparing chromosome specimen slices adopts manual dripping, that is, one hand holds a glass slide, or puts the glass slide on the table, and the other hand holds a dropper for dripping. Such manipulation is not only laborious, but also difficult to control the height of the drop slide, making it difficult to accurately drop the cell solution to a suitable position on the slide. In the existing chromosome droplet preparation process, the influence of human factors in the operation is relatively large, and very skilled technicians are needed to prepare the droplet with better dyeing effect, but it is difficult to standardize the operation and prepare standardized chromosome specimen sheets.

Contents of the invention

The technical problem to be solved by the utility model is to provide a chromosome sample dropping device, which can standardize the dropping process and prepare standardized chromosome sample sheets.

The chromosome sample dripping device of the utility model comprises a frame body, a tray is provided on the frame body, and a glass slide clamping position is provided on the tray; a dropper fixing plate is provided on the top of the frame body.

In one embodiment of the present invention, a dropper is provided on the dropper fixing plate.

In another embodiment of the present utility model, at least one tray support frame is provided on the frame body, and the tray is placed on the tray support frame.

In another embodiment of the present invention, at least one dropper fixing hole is provided on the dropper fixing plate.

In another embodiment of the present invention, the slide holder is provided with a slide, and the slide is located directly below the fixing hole of the dropper.

In another embodiment of the present invention, one end of the slide holder is a slide positioning strip, and the other end is a slide support beam.

In another embodiment of the present utility model, the dropper is a Pasteur dropper.

The chromosome specimen dropping device of the utility model is used to prepare chromosome glass slide specimens, and good chromosome specimen slices can be dripped without operation by skilled technicians. It avoids the influence caused by various artificial uncertain factors of the manual dropping technique, and standardizes the preparation process of the chromosome specimen.

Description of drawings

Fig. 1 is a schematic structural view of a specific embodiment of the present invention.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

The chromosome sample dripping device shown in Figure 1 includes a frame body 1, a tray 2, a tray support frame 3, a dropper 4 and a dropper fixing plate 5, the tray 2 is placed on the tray support frame 3, and the dropper control panel 5 is located on The top of the tray 2 is placed on the top of the frame body 1 , the dropper fixing plate has a dropper fixing hole 6 for fixing the dropper, and the tray 2 is provided with a slide holder 7 .

The four pillars of the frame body 1 of the chromosome sample dropping device are composed of 4 pull rods, the height of the frame body 1 is 110cm, and there are tray support frames 3 for carrying trays at positions 20cm, 40cm, 60cm, 80cm, and 100cm away from the top respectively . The purpose of setting the tray support frames at different heights is to meet the requirements of different heights for different cells in karyotype analysis.

The dropper fixing plate 5 is made of transparent plastic material, and is provided with a dropper fixing hole 6, and the lower end of the dropper 4 passes through the dropper fixing hole 6 and can be fixed. The tray 2 is placed on the tray support frame 3 and can be pulled out freely. On the tray 2 below the dropper fixing hole 6, there is a glass slide clamping position 7, and the glass slide clamping position 7 places a slide glass 10, and the center of the glass slide 10 is located directly below the dropper fixing hole 6, which is convenient for control When dropping the sheet, the cell suspension can be accurately dropped to the center of the slide glass 10 . The dropper fixing plate 5 is provided with 12 dropper fixing holes, and 12 chromosome specimen slides can be dripped at the same time each time.

One end of the slide holder 7 is a slide positioning strip 9, and the other end is a slide support beam 8 with a height of 1 cm. When preparing chromosome specimen slices, one end of the glass slide is close to the slide positioning strip, and the other end is placed on the slide support beam. On the one hand, it can form an inclination, which is convenient for the excess part of the suspension dripped onto the glass slide to flow away, and it is also convenient for placing and taking the slide glass.

It can be seen from the above structure that the chromosome sample dropping device of the present invention is simple in structure, easy to use, standardized in the operation process, reduces the influence of human factors, and can prepare multiple good chromosome sample sheets at one time. The height of the droplet can be adjusted, which meets the requirements of different cells for karyotype analysis on the height of the droplet.
