Description

[Detailed explanation of the invention] a. Purpose of the invention (industrial field of application) The slide glass storage basket according to this invention is designed to hold multiple glass slides with specimens pasted thereon at intervals when preparing microscopic specimens. This is used to stain the specimen by immersing each slide glass in a processing solution at the same time.

(Prior Art) When diagnosing a disease or conducting pathological research in a hospital or research institute, it is common practice to observe tissue pieces excised from a living body under a microscope.

When performing such microscopic observation, a piece of tissue excised from a living body is pasted on a slide glass, the tissue piece is stained, a cover glass is pasted on top of the stained tissue piece, and then the tissue piece is placed under the microscope. I am trying to make observations.

When performing a staining process and needing to process a large number of specimens at once, such as in a hospital, place multiple glass slides in a storage basket with a gap between them. The entire storage basket is immersed in a dyeing solution.

The slide glass storage basket used in such cases has conventionally been constructed as shown in FIGS. 7 and 8, for example. That is, a lower support plate 2, 2 and an upper support plate 3, 3 for supporting a plurality of glass slides are hung between two end plates 1, 1 that are arranged parallel to each other with an interval between them. It is set up so that it can be handed over. Among these, the lower support plates 2, 2 are provided in parallel with each other with an interval between the lower edges of the end plates 1, 1,
Each lower support plate 2, 2 has a plurality of protrusions 4, 4 on its upper edge in accordance with the pitch of the slide glass to be stored.
By forming this, it is formed into a saw-like shape.

On the other hand, each of the upper support plates 3, 3 is formed with a slit-shaped through hole 7 into which a slide glass can be inserted, in accordance with the pitch of the slide glass to be stored, and gradually extends from both side edges toward the center. The inner edges of the lower supporting plates 3, 3 are joined to each other.

The lower ends of wire-shaped support rods 5, 5 are pivotally attached to both sides of the lower ends of the pair of end plates 1, 1, respectively, and the support rods 5, which are pivotally attached to the lower ends of different end plates 1, 1, , 5 are joined to each other by a lateral support plate 6. The upper part of each support rod 5, 5, which protrudes above the horizontal support plate 6, can be elastically engaged with the upper end of the end plate 1, 1.

When staining a specimen attached to a slide glass using the conventional slide glass storage basket constructed as described above, the support rods 5, 5 connected to each other by the horizontal support plate 6 are moved as shown in FIG. Rotate it to the state shown in front to open the sides of the storage basket, and then remove the lower support plate 2,
At the same time, the lower edge of the slide glass is brought into contact between the projections 4, 4 formed on the upper edge of the upper support plate 3,
The upper ends of the glass slides are inserted one by one into the plurality of through holes 7, 7 formed in 3, and the plurality of glass slides are placed between the upper and lower support plates 2, 3 with a space between them. and support it in parallel. Next, the support rods 5, 5, which had been rotated downward until then, are rotated upward as shown in the back of FIG.
The upper end portions and the upper end portions of the end plates 1, 1 are engaged with each other to prevent the slide glass supported between the upper and lower support plates 2, 3 from falling off laterally.

When a plurality of slide glasses can be stored inside the storage basket in this way, the hook 13 fixed to the center of the upper surface of the upper support plates 3, 3 is hooked to the hanging part of the staining device, and the plurality of slide glasses are A storage basket containing slide glasses is sequentially immersed in a plurality of containers storing a staining treatment solution.

In addition to the structure shown in FIGS. 7 and 8, the structure of the storage basket is such that both ends of the horizontal support plates 6, 6 are fixed to the end plates 1, 1, and a slide glass is stored. There is also one in which each slide glass is inserted from above the storage basket.

(Problems to be Solved by the Invention) However, the conventional slide glass storage basket constructed and used as described above has the following disadvantages.

That is, the slide glass storage basket is sequentially immersed in a plurality of containers storing different processing solutions, but the lower edges of the upper and lower support plates 2 and 3 provided to support the upper and lower ends of the slide glass are Since the support plates 2 and 3 are horizontal, the processing liquid that adhered to each of the support plates 2 and 3 during immersion tends to remain attached to the support plates 2 and 3 even after being pulled up from the treatment liquid.

As the staining operation progresses, the processing solution that remains attached to the slide glass storage basket is sent into the next container and mixes with the processing solution in this container. Although the amount of processing liquid that mixes at a time is small, as the dyeing process is repeated, the amount of mixing gradually increases, and the performance of the processing liquid deteriorates.
It becomes impossible to perform a good dyeing process.

Furthermore, in the case of a storage basket in which a slide glass is inserted from above, the sample attached to the surface of the slide glass and not yet covered with a cover glass is scraped off by the edges of the through holes 7, 7, etc. Samples adhering to the edges of the through holes 7, 7 may adhere to the surface of the slide glass inserted into the adjacent through hole 7. This tendency is particularly noticeable when the sample attached to the surface of the glass slide has been centrifugally smeared, but if a sample other than the original sample adheres to the surface of the slide glass, it may lead to misdiagnosis, etc. This is not desirable as it may cause

The slide glass storage basket of the present invention suppresses the amount of processing liquid that adheres when immersed in the processing liquid, and can freely support the slide glass by suppressing only the lower edge and both side edges of the slide glass.
This eliminates all of the above-mentioned inconveniences.

b. Structure of the invention (means for solving the problem) The slide glass storage basket according to the invention consists of two end plates, a plurality of support rods with a circular cross section, a handle, and a handle fixed to the center of the handle. It is composed of the following.

Among these, the outer circumferential surface of the plurality of support rods has a plurality of grooves that are wide at the entrance and tapered gradually toward the back, depending on the pitch of the slide glass to be stored. It is formed at intervals.

A plurality of support rods having a plurality of tapered grooves formed at equal intervals on their outer peripheral surfaces are spanned between two end plates provided in parallel with an interval between them.

That is, the upper parts of the two end plates disposed parallel to each other are placed at the same height position by sliding a plurality of parallel upper support rods parallel to each other and inside the grooves formed on the respective outer peripheral surfaces. The side edges of the glass are spanned at intervals that allow for free engagement.

Also, intermediate support rods are provided directly below the upper support rods so as to span between the two end plates, and the upper support rods and intermediate support rods are arranged parallel to each other with an interval between them. Both side edges of the slide glass inserted between the slide glass and the slide glass are held down at two positions, one at the upper part and the other at the middle part.

Furthermore, a lower support rod is spanned between the lower ends of the two end plates and between the intermediate support rods that are arranged parallel to each other. Furthermore, a handle with a hook fixed at the center is attached to the upper ends of the surfaces of the two end plates.

(Function) When storing a slide glass in the slide glass storage basket of the present invention configured as described above, the lower end of the slide glass to be stored is placed between two adjacent upper support rods on both sides of the slide glass. Insert so that the edges engage inside the grooves of the two upper support rods.

Once the slide glass has been inserted between the two upper support rods, the slide glass is further lowered using the upper support rods as a guide. By this lowering operation, the lower end of the slide glass passed between two adjacent intermediate support rods and reached the lower support rod, and the lower edge of the slide glass was formed on the outer peripheral surface of this lower support rod. Engage in the groove.

In this state, the slide glass is held down at both sides by the upper support rod and the middle support rod to prevent it from falling on both sides, and its downward movement is prevented by the lower support rod. The grooves formed on the outer circumferential surface of each support rod are wide at the entrance and taper to become narrower toward the back, so the slide glass and support rods are firmly held inside the storage basket. The parts that come in contact with each other are only the edge of the slide glass and the inner part of the groove, and a part of the sample attached to the surface of the slide glass does not adhere to the support rod.

The storage basket that stores multiple slide glasses in this way can be used for staining samples attached to slide glasses that have been immersed in a container containing a processing solution, just as in the case of the conventional storage basket described above. However, in the case of the storage basket of the present invention, the cross section of the plurality of support rods for supporting the slide glass is circular, so that when the storage basket is taken out of the processing solution, the processing solution spills onto the surface of the storage basket. It is difficult for the product to remain attached to the surface.

(Example) Next, the present invention will be explained in more detail while explaining the illustrated embodiment.
