Description

[Detailed Description of the Invention] The present invention relates to a slide plate used when examining sediments of blood, urine, and other body fluids using a microscope. Conventionally, when testing a sample, two drops of the liquid to be tested are placed on the surface of a rectangular glass plate at a fixed distance, a square cover glass is placed on top of the drop, and the sample is spread thinly. The method used is to look through a microscope. However, with this method, sediment specimens are prepared for every two specimens, so there is a risk that the specimens may be mixed together, and each time two specimens are examined microscopically, it must be removed from the stage and replaced, resulting in poor work efficiency and poor glass quality. The disadvantage is that the cost of consumables such as plates and cover glasses increases. Therefore, in order to eliminate this drawback,
A slide plate as described in Publication No. 47892, or a further improved version of the slide plate published in 1983.
A slide plate as described in Publication No. 71538 is disclosed. These systems have testing chambers drilled at regular intervals with narrow gaps or specimen chambers formed by welding adjacent sections, and although they have their own advantages, However, there are drawbacks such as being labor intensive and expensive to manufacture, and not necessarily being easy to operate when microscopically examining a large number of specimens at once.

Therefore, the inventor conducted extensive research in order to provide a low-cost inspection slide that was easy to operate and manufacture without sacrificing the basic purpose of ensuring accurate inspections, and the results were put forward into practical application. 1980-
It was proposed as No. 51756 and No. 51757. However, in the testing chamber formed on the sliding plate, the upper plate and lower plate may be too close together, or the plates may warp and leave too much space between them, making it difficult for the specimen to spread uniformly and quickly during use. In some cases, it may not be carried out, so
The present invention improves this point and provides a structure in which the specimen is always diffused uniformly. Examples will be explained below.

A is a lower plate made of a circular thin hard synthetic resin plate, and is provided with a large number of elongated notches 1 at regular intervals from the periphery toward the center, thereby creating the same number of fan-shaped parts 2.
is formed. 3 is a gripping piece, and 4 is an insertion hole provided in the center of the lower plate. B is a transparent upper plate made of a thin hard synthetic resin plate, whose outer periphery almost matches the outer periphery of the lower plate, and from the outer periphery protrude tongue pieces 5 of the same number as the spacing of the notches 1. It has a donut-shaped overlapping part 6 which is narrower than the length of the notch 1. A plurality of fixing pieces 7 for joining with a lower plate A, which will be described later, protrude toward the center from the inner peripheral edge of this overlapping portion 6. FIG. 1 is a plan view showing a state where the upper plate B is stacked on the lower plate A, and there are many fan-shaped parts 2 formed by the notches 1 of the lower plate A.
Both plates are overlapped with their centers aligned so that the tongue piece 5 is located at the center of the outer side of the plate, and the upper and lower plates A and B are welded and joined together at the tip of the fixing piece 7 to be integrated. Further, each fan-shaped portion 2 is also provided with minute protuberances 8 of approximately 0.1 mm in height at two locations adjacent to its outer edge, and both the upper and lower plates are welded at these locations. Micro bump 8
The appropriate height is 0.1 mm to 0.08 mm, and the location may be the back surface of the overlapping portion 6, and the location and number thereof may be determined as appropriate depending on the situation.

As a result, as shown in Figs. 2 and 3, an extremely narrow examination chamber C is formed with a vertical interval of approximately 0.1 mm to 0.08 mm due to the fan-shaped portion 2 formed by the notch 1 and the overlapping portion 6 above it. A large number of them are formed, and the spacing between them is always kept constant. Note that the shape of the upper plate B is not limited to the above-mentioned shape, and as long as it includes the overlapping portion 6, the tongue piece 5, and the fixing piece 7, it may have any shape. 9 is a number stamped on the inside of each examination chamber C, indicating the chamber number, and 10 is a raised protrusion provided to prevent fingers from slipping when rotating the slide plate.

How to use this slide board is as follows. first,
Holding the gripping piece 3, the sample is directly scooped out from the test tube using the tongue piece 5 and attached to the back surface of the tongue piece 5. The attached specimen enters the narrow gap in the examination chamber C by capillary action and is diffused and retained within the chamber. Next, the specimens are held in adjacent examination chambers C in the same manner.
On the other hand, on the stage of the microscope, a rotary support D made of transparent hard synthetic resin having a support shaft 11 and a window hole 12 as shown in Fig. 4 is placed, and the slide plate of the present invention is placed on it. Insert the insertion hole 4 into the support shaft 1
1, so that it can rotate freely around this, and the window hole 1
Raised protrusions 10 so that each examination chamber C is located in two parts
Inspect each specimen by placing your fingertip on it and rotating it sequentially.

Since the present invention is configured as described above, it has the following effects.

(b) The mirror between the examination room and the examination room is separated from the adjacent room by a notch without forming a side wall as in conventionally known mirrors, so manufacturing is easy and costs can be reduced.

(b) Since the upper and lower plates of each examination chamber are spot welded at the microscopic protrusions, the distance between the two plates is always maintained constant, and the specimen is uniformly diffused by capillary action.

C. To store the sediment in the examination chamber, it is only necessary to scoop it with the underside of the tongue formed on the periphery of the upper plate and deposit a small amount, which is an easy operation.

D. It is extremely efficient as it allows a large number of specimens to be accommodated in a number of examination rooms at once, placed on stages, and subjected to microscopic examination one after another.
