For example, the red staining solution is contained in a red liquid bottle 631, and the buffer solution or the rinsing solution such as water can be contained in a transparent or white liquid bottle 631, so as to be easily recognized by the experimenter and prevent the wrong staining solution from being dropped. It is understood that in other embodiments, a label may be disposed on the liquid bottle 631, which may also achieve the effect of facilitating the identification of the experimenter and preventing the wrong staining solution from being dropped. Similarly, serial number labels can be provided on the side vertical plates 5253 of the slide accommodating chamber 525 or on the support frame 521 of the slide holder 52 for indicating the staining sequence of the slides.

In this embodiment, two second stoppers 646 are further connected to the container pointer 642, and the two second stoppers 646 are rotatably connected to opposite sides of the container pointer 642, respectively. In the present embodiment, each of the second position-limiting members 646 is substantially rod-shaped, and one end thereof is rotatably connected to the container pointer 642 by a rotating shaft, a hinge, or the like. Under the action of external force, the two second position-limiting members 646 can rotate to a substantially vertical position relative to the container pointer 642 and respectively abut against the two opposite sides of the hook rod 65 pointed by the container pointer 642, so as to prevent the container positioning member 64 from rotating freely (fig. 12); under the action of external force, the two second retaining members 646 can rotate to a substantially horizontal position relative to the container indicator 642, and at this time, the second retaining members 646 disengage from the hook rod 65 to allow the container positioning member 64 to rotate (fig. 10).

During the use, move laboratory slide staining device 100 to the suitable position on the experiment operation panel through walking wheel 25, mention pull ring 6332, rotate and make a movable rod 6331, locate to remove cock body 6334 from inlet 6311, according to the experiment needs, add dyeing liquid, flush fluid or buffer solution etc. in going into each liquid bottle 631 from inlet 6311. For example, in the present embodiment, dyeing of two colors of purple and yellow is performed, a purple dye is contained in the purple liquid bottle 631, a yellow dye is contained in the yellow liquid bottle 631, and a buffer solution, tap water, or the like is contained in the white liquid bottle 631 as a rinse solution. After the liquid is added, the actuating rod 6331 is rotated by the pull ring 6332 to cover the stopper 6334 on the liquid inlet 6311, but not tightly, so as to ensure that air can enter the liquid bottle 631. Slides 200 (bacterial smears which are dried and fixed in advance) to be dyed are inserted into the slide accommodating chambers 525 along the slide inserting grooves 5256 of the two side vertical plates 5253, and if a plurality of slides 200 are to be dyed, the plurality of slides 200 are respectively inserted into the plurality of slide accommodating chambers 525.

By the rotation of the rotating disc 61, the liquid bottle 631 (purple in this embodiment) containing the first dyeing liquid to be dropped is rotated to the position pointed by the container pointer 642, and the second limiting members 646 are rotated, so that the two second limiting members 646 respectively abut against the two opposite sides of the hook rod 65 to prevent the container positioning member 64 from rotating freely; flow control valve 635 is adjusted to allow the flow rate of the liquid from liquid line 634 to meet the experimental operating requirements. By the rotation of the rotating disk 51, the first slide 200 to be stained is rotated to the position where the slide indicating needle 534 is directed, and at this time, the first slide 200 is positioned directly below the first liquid bottle 631 of the staining solution to be dropped so as to be dropped for staining. The first limiting members 538 are rotated, so that the two first limiting members 538 abut against two opposite sides of the connecting rod 523 respectively, so as to prevent the slide positioning member 53 from rotating freely.

The flow control valve 635 of the first liquid bottle 631 of the staining solution to be dropped is opened, and the staining solution flows out of the liquid outlet pipe 634 and is dropped onto the bacteria-coated surface of the slide 200. After the dyeing time is over, the second position-limiting members 646 are rotated so that the two second position-limiting members 646 disengage from the hook lever 65, and then the rotating disc 61 is rotated. By the rotation of the rotary disk 61, the rinse liquid is turned to the position at which the container needle 642 is directed, and the slide accommodating chamber 525 is further rotated so that the slide accommodating chamber 525 is inclined downward toward the support 4. The flow control valve 635 for the washing liquid is opened, the washing liquid flows out through the liquid outlet pipe 634 and onto the slide 200, and the washing liquid flows into the waste liquid basin 3 from the gap between the connecting rods 523 and enters the waste liquid bottle 37 through the liquid outlet pipe 36. The flow rate of the washing liquid should be controlled within a range such that the slide accommodating chamber 525 does not rotate when impacted by the washing liquid, and it can be adjusted to a desired flow rate range by the flow control valve 635. After washing, the slide accommodating chamber 525 is reset to the horizontal state, and the second step of dyeing with the yellow dyeing liquid is performed by the same operation, and then the first slide 200 is washed, i.e., the dyeing operation is completed. The second slide 200 is then rotated to the position pointed by the slide locator 53, as described above, to stain the second slide 200. The above steps are repeated until the staining operation of all the slides 200 on the slide support mechanism 5 is completed. The removal of the slide 200 can be performed after the slide 200 is stained or after all slides 200 on the slide support mechanism 5 are stained. During the staining process, the operator can know the progress of the current staining operation according to the container positioning member 64 and the slide positioning member 53. For example, when the operator moves back halfway in the process of staining the second slide 200 with the purple staining solution in the first step, the second slide is currently being stained by the purple staining solution by the slide positioning member 53, and the second slide is stained with the purple staining solution by the container positioning member 64.

It is understood that, in other embodiments, all the slides 200 of the slide bearing mechanism 5 may be first stained with the purple staining solution according to the staining procedure, and at this time, the liquid bottles 631 on the liquid bearing mechanism 6 all contain the purple staining solution; after all the slides 200 are dyed by the purple dyeing liquid, the purple liquid bottle 631 on the liquid bearing mechanism 6 is taken down, the liquid bottle 631 containing the washing liquid is hung, and then all the slides 200 on the slide bearing mechanism 5 are washed; after all the slides 200 are washed, the liquid bottle 631 containing the washing liquid on the liquid bearing mechanism 6 is taken down, the liquid bottle 631 containing the yellow dyeing liquid is hung, and then all the slides 200 on the slide bearing mechanism 5 are dyed by the yellow dyeing liquid and washed after dyeing.

It will be appreciated that in other embodiments, the base 2 may be omitted and the laboratory slide staining apparatus 100 moved by manual force when it is desired to move the laboratory slide staining apparatus 100.

It is understood that in other embodiments, the rotating disc 51 may be rotatably connected to the supporting column 41 through a bearing, and similarly, the rotating disc 61 may be rotatably connected to the supporting column 41 through a bearing. The slide positioning member 53 and the container positioning member 64 can also be directly fixedly attached to the support column 41.

The above description is for the detailed description of the preferred possible embodiments of the present invention, but the embodiments are not intended to limit the scope of the present invention, and all equivalent changes or modifications accomplished under the technical spirit suggested by the present invention should fall within the scope of the present invention.
