Description

[Detailed description of the invention] <Technical field> This invention relates to a slide glass stain cleaning device, and more specifically, it is used in the fields of medicine and biological research to clean test samples, etc. for slide glasses used in various examinations and tests. It is used for dyeing and cleaning.

<Prior art> The slide glass described above is used for various microscopic examinations and tests by attaching test samples such as biological tissues and microorganisms. Since then, inspections have been carried out.

A common method for staining a test sample on a slide glass is to use a dropper or the like to drip a staining solution onto the test tissue or the like on the slide glass.

However, the operation of injecting the staining solution onto each glass slide using a dropper or the like is extremely troublesome and extremely inefficient when a large number of inspections and tests are performed. Also, during work, the staining solution tends to get on your hands or scatter around, staining the surroundings, and if the dropper or your hands come into contact with the test tissue on the slide glass, it can damage the test sample or adversely affect the test results. There was also the possibility that it would cause

In addition to the above-mentioned staining work, we also wash the glass slides with water to remove excess staining solution.
Similar problems occur when cleaning used glass slides.

<Purpose> Therefore, the purpose of this invention is to solve the above-mentioned drawbacks of the conventional technology, and to make it possible to carry out staining and cleaning operations on a large number of slide glasses very efficiently, and to do so in a clean manner without staining hands and surroundings. We are trying to provide equipment that can do the job.

<Structure> In order to achieve the above object, a liquid passage groove with both longitudinal ends open is formed in the rectangular plate-shaped main body, and both longitudinal ends of the liquid passage groove are opened. A holding step for placing a slide glass is formed on the inside of the convex wall to form a gap between the slide glass and the bottom surface of the liquid passage groove. , is characterized by forming a protrusion that can come into contact with the top surface of the glass slide.

<Example> Next, an example of this invention will be described below with reference to the drawings.

As shown in FIG. 1, a main body 1 has an elongated rectangular plate shape, and has highly protruding convex walls 10, 10 formed on both ends in the longitudinal direction.
A liquid passage groove 11 is formed in the center of 0 and 10 along the longitudinal direction, and is low and flat and open to both short sides. Holding step portions 12, 12 are recessed in the convex walls 10, 10 over substantially the entire length excluding both ends in the longitudinal direction. Both ends are bridged so that a plurality of slide glasses S can be inserted and placed side by side. The entire length of the holding step 12 is formed so that when a predetermined number of slide glasses S are inserted and placed, only a gap is created that is large enough to prevent each slide glass S from moving. A relatively narrow gap c is formed between the holding step 12, that is, the slide glass S, and the bottom surface of the liquid passage groove 11.

Next, 2 is a lid body, which is placed on the top surface of the main body 1,
The slide glass S is held down and fixed from above. Reference numeral 20 denotes a step portion for fitting, which fits inside the convex walls 10, 10 of the main body 1 and is fitted and locked. Reference numeral 21 denotes a rectangular ridge-shaped protrusion, which is formed in a small protrusion on the lower surface of the lid body along the longitudinal center line of the lid body 2, and contacts the center of the top surface of each slide glass S to hold the slide glass S. Press from above to secure.

Regarding the use of the dye washer mentioned above, the second
This will be explained with reference to the figures and FIG. First, main body 1
Slide glasses S to which test samples such as test tissues are attached are placed side by side on the holding stage 12 of the slides. At this time, the glass slide S is placed so that the surface to which the test sample is attached is the lower surface.
Then, the lid body 2 is fitted to the upper part of the main body 1, and the projection part 21 is brought into contact with the upper surface of the slide glass S to fix it.

In this state, tilt the entire main body 1 and lid 2 in the longitudinal direction, and connect the slide glass S and the bottom surface of the liquid passage groove 11 from the open part of the liquid passage groove 11 on the short side edge, which is the upper end of the slope. Pour the staining solution into the gap c. The staining liquid injected into the gap c spreads over the entire lower surface of the slide glass S by capillary action and downward action along the slope, coloring the test sample beam-colored. As a result, the finish of the beam color becomes uniform, and the occurrence of uneven dyeing and dyeing defects is reduced. Further, the dyeing solution after dyeing is discharged from the lower end of the liquid passage groove 11, that is, from the open portion at the end in the transverse direction.

Once the staining work is finished as described above, you can immediately remove the lid 2 and take out the slide glass S. However, if there is excess staining solution on it, use distilled water instead of the staining solution after staining. Wash and remove unnecessary staining solution. Furthermore, if a used slide glass S after an examination or the like is completed is set in this stain cleaning device, cleaning work for reuse can be performed.

Among the staining and cleaning devices described above, the main body 1 and the lid 2 are made of glass or hard transparent plastic to prevent dirt from adhering to them, and to allow the staining and cleaning conditions of the slide glass S to be checked from the outside. This is confirmed and suitable. However, in the case of hard plastic, it is necessary to use a material with excellent chemical resistance so that it will not be attacked by dyeing liquid or the like. Furthermore, as for the lid body 2, it is also possible to use a metal one.

Next, the holding step portion 12 of the main body 1 only needs to be able to place the slide glass S by a portion of its width at both ends. In addition to the illustrated structure in which the holding step portion 12 is continuously formed for the length of a plurality of slide glasses S, a plurality of holding step portions divided for each slide glass S are formed, and each It is also possible to enable the slide glasses S to be placed separately. Gap c between the holding step 12 and the bottom of the liquid passage groove 11
It is sufficient to have a relatively narrow gap through which a liquid such as a staining liquid can pass, and in particular, a narrow gap is better in order to make use of the capillary action mentioned above to spread the staining liquid etc. throughout, and usually about 1 mm. A gap of 1 is suitable. Further, the holding step portion 12 may be recessed in the convex wall 10 or may be formed to protrude from the convex wall 10 toward the liquid passage groove 11 side.

Next, if the lid body 2 can be fitted and attached to the main body 1, a fitting stepped portion 20 is provided as shown in the figure.
In addition to the one that fits inside the convex wall 10, the convex wall 10
It is also possible to use a type that fits over the outside of the body. Furthermore, an engagement function consisting of a protrusion, a recess, etc. that can be engaged with each other may be formed at the fitting location between the main body 1 and the lid 2. Further, the protrusion 21 can be formed at any location on the lower surface of the lid body 2 as long as it can come into contact with a part of the upper surface of the slide glass S and press it from above to fix it. For example, a plurality of protrusions 21 can be formed They can be formed at certain locations, along both end sides in the longitudinal direction, or intermittently in the longitudinal direction.

<Effects> According to the staining and cleaning device for the slide glass S of this invention, there is a space between the slide glass S and the bottom surface of the liquid passage groove 11 on the inside of the convex walls 10 at both ends along the longitudinal direction of the liquid passage groove 11. Slide glass S forming gap c
Since the holding step 12 for placement is formed, when a large number of slide glasses S are placed on the holding step 12, the slide glass S is formed between the slide glass S and the bottom surface of the liquid passage groove 11. By pouring the staining solution into the gap c, it is possible to stain a large number of slide glasses S at once, compared to the conventional method of manually staining each slide glass using a dropper etc. Dyeing can be done much more efficiently, and your hands and surroundings won't get dirty.

Moreover, the lid 2 is fitted onto the top surface of the main body 1 housing the slide glass S, and the slide glass S is pressed and fixed by the protrusion 21 of the lid 2.
During the staining process, there is no need to touch the slide glass S at all, and your hands will not get dirty. Also, since the staining solution only flows from one end to the other through the gap c, the staining solution will not splash around. You can work extremely cleanly without worrying about it scattering or getting stuck. Moreover, since the slide glass S is not touched at all, it is easy to handle, eliminating the problems of conventional methods such as touching the test tissue and damaging the sample value or adversely affecting the test results. Traditional skills are no longer required.

Furthermore, the staining and cleaning device of this invention is highly flexible and can be used not only for the above-mentioned staining work, but also for cleaning slide glasses S in exactly the same way, and can exhibit various practical effects. It is.
