Description

  The present invention relates to a preparation storage case that can store a preparation for microscopic observation on which a thin piece of a biological specimen such as a pathological tissue is affixed, and in particular, even if a lateral stress is unexpectedly applied due to an earthquake or the like, The present invention relates to a safe and easy-to-use preparation storage case that can be prevented from jumping out and falling, and can easily be pulled out when taking out the preparation in the storage section.

  Biological tissues such as pathological tissues are usually examined by placing the tissue excised from the affected area of a patient in a container having a large number of through holes called cassettes, treating with chemicals with formalin solution, etc., and then calling it an embedding tray. After placing the chemical-treated tissue in the container to be placed, the cassette was placed on the embedding tray, the molten paraffin was allowed to flow into the embedding tray from above the cassette, and the tissue was embedded outside the bottom of the cassette It is a so-called embedding block to which a paraffin block is attached. This embedding block is fixed on a device called a microtome with a paraffin block that embeds the tissue facing up, then sliced, the cut tissue piece is placed on a slide glass, stained, and covered with a cover glass. The prepared preparation is observed with a microscope.

  The prepared slide is stored in a prepared case so that it can be used for re-examination. When it is desired to observe the pathological tissue again, a predetermined preparation is taken out from the preparation case and observed with a microscope.

  As an organizing case for organizing samples such as embedding blocks and slide glasses (preparations), it contains an embedding block storage section that accommodates a large number of embedding blocks divided vertically and horizontally and accommodates slide glasses. An arrangement case has been proposed in which a slide glass storage unit is provided, and the arrangement of the slide glass by the slide glass storage unit corresponds to the arrangement of the embedded blocks by the embedded block storage unit (Patent Document 1).

  However, in the organizing case like the above-mentioned Patent Document 1, although it is easy to take out the target embedding block or slide glass, in order to store the embedding block or slide glass in a laid state, per embedding block, or The required space per glass slide becomes quite large. In addition, although a large amount of used embedding blocks and used slide glasses are generated, the frequency of these reexaminations is not so high, resulting in the disadvantage that a large storage space is required for samples that are used infrequently.

On the other hand, a specimen multi-rack in which a coiled spring is stretched in the longitudinal direction near the bottom of the drawer and a slide glass is sandwiched between the springs is sold (Non-Patent Document 1).
Since such a rack stores the slide glass vertically, it can store a large amount of preparation in a small space. However, since a spring is interposed between the slide glass, the amount of the slide glass stored is reduced, and the slide glass may be stored by skipping one or two springs. In this case, the slide glass is stored. The amount is even smaller. Furthermore, a hook for hooking a finger when pulling out is projected downward on the front of the drawer, so there is a possibility that clothes will be hooked on this hook. There is a problem that they cannot be stored compactly side by side without a gap.

  Further, in both cases of Patent Document 1 and Non-Patent Document 1, when a lateral stress is applied due to an earthquake or the like, the housed slide glass and the embedded block are heavy, and the drawer housing them has a momentum. It often jumps out of the case and falls to spoil precious samples, and there is a risk of serious injury if the popped out drawer hits the viewer.

Hagiten Net, Specimen Multirack, [Search March 12, 2009], Internet <URL: http://www.hagitec.co.jp/hagiten/as/as2/as465.ht>

  In view of such a situation, the present invention solves the above-mentioned problems of the prior art, and can store a large amount of preparations in a small space. It is an object to provide a storage case.

In order to achieve the above object, claim 1 of the present invention is a drawer type in which a rectangular parallelepiped housing portion having an open top is inserted into a rectangular parallelepiped outer frame portion having one open side. The preparation storage case of
A stopper piece A projects from the bottom surface of the bottom plate of the housing portion. The stopper piece A has a surface on the front side in the pulling direction substantially perpendicular to the bottom surface of the housing portion, and a surface on the back side in the pulling direction. It is a slope with a shallow angle to the bottom,
On the upper surface of the bottom plate of the outer frame portion, a stopper piece B having a substantially vertical surface capable of abutting with a substantially vertical surface on the front side in the pulling direction of the stopper piece A is projected .
A handle hole that is used as a handle by inserting a finger into the side plate on the front side in the pull-out direction of the housing part is formed,
The estimated insertion length L2 of the finger to be inserted into the handle hole is longer than the drawing length L1 until the vertical surface of the front side of the stopper piece A and the vertical surface of the stopper piece B of the outer frame abut each other. The feature preparation storage case is the content.

According to a second aspect of the present invention, the preparation storage case according to the first aspect is characterized in that the handle hole is covered with a dustproof cover made of a flexible member.

Claim 3 of the present invention will become dust cover is a flexible member, the slide housing of claim 2, characterized in that radially 3-8 cuts out direction is provided from the central portion Case content.

In the preparation storage case according to the present invention, a stopper piece A having a surface on the front side in the pulling-out direction substantially perpendicular to the bottom surface of the storage portion protrudes from the bottom surface of the bottom plate of the storage portion, and the top surface of the bottom plate of the outer frame portion. Since the stopper piece B having a substantially vertical surface that can collide with the substantially vertical surface on the near side in the pulling direction of the stopper piece A protrudes, a lateral force is unexpectedly applied to the housing portion in the event of an earthquake or the like. Even when the storage portion is added, the substantially vertical surfaces of the stopper piece A of the storage portion and the stopper piece B of the outer frame portion collide, and the storage portion can be prevented from jumping out of the outer frame portion and falling. .
In addition, when taking out the preparation in the housing portion, the housing portion is pulled until the substantially vertical surfaces of the stopper piece A and the stopper piece B of the outer frame portion are brought into contact with each other, and then the housing portion is slightly lifted to stop the stopper piece A. By pulling over the piece B, the accommodating portion can be easily pulled out.
When accommodating the accommodating part in the outer frame part, the accommodating part is automatically pushed into the opening of the outer side of the outer frame part by simply inserting the accommodating part into the opening on the side of the outer frame part so that the accommodating part is automatically Because it can be pushed up and overcome, it can be easily accommodated.

  A handle hole is formed in the side plate on the front side in the drawer direction of the housing portion, and the estimated insertion length L2 of the finger inserted into the handle hole is set to the vertical surface on the near side of the stopper piece A and the stopper piece B of the outer frame portion. If it is longer than the drawing length L1 until the vertical surface abuts, the tip of the inserted finger is placed on the outer frame when the container is lifted so that the stopper piece A gets over the stopper piece B after the collision. Since it hits the upper edge of the opening of the part and does not hit the preparation in the housing part, it is possible to prevent the preparation from colliding with the opening upper edge of the outer frame part and being damaged.

  Covering the handle hole with a dustproof cover prevents dust and dirt from entering the interior of the housing portion, thus preventing contamination of the slide. Further, the dust cover is made of a flexible member, and by providing 3 to 8 notches radially outward from the center portion, the cover is pushed inward when inserted into a substantially central portion of the cover. On the other hand, when the finger is pulled out, the pushed-open cover returns to its original state. Therefore, the opening and closing operation of the cover is unnecessary and the workability is good.

  In the preparation storage case of the present invention, as shown in FIGS. 1 to 4, a rectangular parallelepiped housing portion 3 opened upward is inserted into a rectangular parallelepiped outer frame portion 2 opened on one side. In the drawer-type preparation storage case 1, a stopper piece A: 3a is projected on the bottom surface of the bottom plate of the storage portion 3, and the stopper piece A: 3a has a front surface in the pull-out direction on the bottom surface of the storage portion. On the other hand, the surface on the back side in the pull-out direction is a slope 3c having a shallow angle with respect to the bottom surface of the housing portion, and the top surface of the bottom plate of the outer frame portion 2 is a substantially vertical surface of the stopper piece A: 3a. A stopper piece B: 2a having a substantially vertical surface 2b capable of colliding with 3b is projected.

The outer frame portion 2 used in the present invention is a rectangular parallelepiped box-shaped member capable of accommodating the accommodating portion 3 accommodating the preparation. As shown in FIG. 1, the outer frame portion 2 is opened on one side, and the housing portion 3 can be drawn out and put out from the opening as shown in FIG.
The accommodating portion 3 is a rectangular parallelepiped box-shaped member that can accommodate a preparation. The upper portion of the storage portion is opened, and the preparation can be stored compactly from the opening.
In addition, since the preparation is generally quite small and has a large number, in order to arrange and store them easily, usually, several elongated storage portions 3 are stored in one outer frame portion 2, The housing portion 3 is provided with individual pulling direction restricting means so that the housing portion 3 can be pulled out in the correct direction.
In the embodiment shown in FIG. 1 to FIG. 4, the two rails 2 c provided on the upper surface of the bottom plate of the outer frame portion 2 and the both edges of the lower surface of the bottom plate of the housing portion 3 are provided as the drawing direction restricting means. A guide rib 3h is used, thereby preventing a side slip of the housing portion 3 so that the housing portion 3 can be reliably inserted and removed in the front-rear direction.

In the present invention, using the stopper piece A: 3a provided on the lower surface of the accommodating portion 3 and the stopper piece B: 2a provided on the outer frame portion 2, lateral stress is applied to the accommodating portion 3 due to an earthquake or the like. Even in this case, the accommodating portion 3 is prevented from falling off.
For example, as shown in FIG. 2, the stopper piece 3 a has a surface on the near side in the pulling direction of the housing portion 3 as a substantially vertical surface 3 b with respect to the bottom surface of the housing portion 3 and a surface on the far side in the pulling direction. The inclined surface 3c has a shallow angle with respect to the bottom surface of the portion 3.

The positions of the substantially vertical surface 2b of the stopper piece A: 3a and the stopper piece B: 2a are the same as the position of the substantially vertical surface 3b of the stopper piece A: 3a when the accommodating portion 3 is accommodated to the back of the outer frame portion 2. Stopper piece B: The substantially vertical surface 2b of 2a opposes, and when the stress is applied to the accommodating portion 3 from the front side in the pulling-out direction, the stopper piece B slightly moves and moves to a substantially vertical surface 3b. Although it is not particularly limited as long as it is arranged so as to abut against 2b, it is preferable to arrange the outer frame part 2 and the accommodating part 3 on the front side in the pulling direction because it has a large effect of preventing the accommodating part 3 from popping out. .
In the case of the embodiment shown in FIGS. 1 to 4, the stopper piece A: 3a is provided at both edges of the accommodating portion 3 on the front side in the pulling direction, and the stopper piece B: 2a is partially intermittently provided on the rail 2c. An example is shown in which the rear side surface of the short rail on the front side in the pulling direction is used as the substantially vertical surface 2b.
In addition, as shown in FIG. 5, the stopper piece A: 3a of the accommodating portion 3 is provided at a position that does not overlap the rail 2c, and the outer side of the stopper piece A: 3a when the accommodating portion 3 is pulled out is blocked. You may provide the stopper piece B: 2a of the frame part 2. As shown in FIG.
The pull-out length L1 when the substantially vertical surface 3b of the stopper piece A: 3a and the substantially vertical surface 2b of the stopper piece B: 2a abut each other is not particularly limited. If it is too long, the center of gravity of the entire preparation storage case 1 may come off and fall together with the case 1. Therefore, although it depends on the size of the preparation storage case 1, it is usually preferred to be about 5 mm to 50 mm (see FIG. 11).

The side plate 3e on the front side of the housing part 3 in the pulling direction (hereinafter sometimes referred to as the front plate 3e) is preferably provided with a handle for making it easy to pull out the housing part 3. The shape of the handle is not particularly limited. However, in the case of a handle protruding from the front plate 3a, clothes or the like may be caught by the handle, so that a finger may be inserted and hooked inside the housing portion 3 to be pulled. A method of drilling the handle hole 3f is preferable so that it is possible.
The estimated insertion length L2 of the finger to be inserted into the handle hole 3f is the pull-out length when the substantially vertical surface 3b of the stopper piece A: 3a and the substantially vertical surface 2 of the stopper piece B: 2a abut each other. When the length is longer than L1, the preparation can be safely put in and out without damaging the preparation when the accommodating portion 3 is pulled out for the reason described later.
For example, in general, when the handle hole 3f is provided, the container 3 is usually pulled out by inserting the first joint portion of the finger into the handle hole 3f and hooking it inside the container 3, but in the case of an adult, Since the length of the fingertip from the first joint is about 15 to 30 mm, the estimated insertion length L2 of the finger to be inserted into the handle hole 3f is 15 to 30 mm, and the above extraction length L1 is set to about 5 to 10 mm in accordance with this. Is preferable.

When the handle hole 3f is provided, it is preferable to cover the handle hole 3f with a dust-proof cover 3g in order to prevent dust and dirt from entering through the handle hole 3f.
The shape and structure of the dustproof cover are not particularly limited as long as it covers the handle hole 3f and closes the handle hole 3f. For example, as shown in FIG. A dust-proof cover 3g formed by sticking a sheet made of a flexible member that has been cut so as to be divided into covers is covered with the handle hole 3f, and when the finger is inserted, the dust-proof cover 3g is pushed inward, When the finger is pulled out, the pushed dust cover returns to its original state and closes the handle hole 3f, which is convenient because the dust cover can be automatically opened and closed. Further, as shown in FIG. 7, a dustproof cover 3g pivotally attached above the handle hole 3b is used, and when the accommodating portion 3 is pulled out, the dustproof cover 3g is rotated upward to put a finger into the handle hole 3f. You may make it insert.

6 and 7, an example in which the dustproof cover 3g is provided on the outer surface side of the front plate 3e is described. However, as shown in FIGS. 8 and 9, the dustproof cover 3g may be provided on the inner surface side of the front plate 3e. In this example, the dust-proof cover 3g is suspended from the vicinity of the opening upper edge 2d of the outer frame portion 2, and is pivotally attached to the outer frame portion 2 near the upper end thereof. The dustproof cover 3g is biased outward by an elastic mechanism (not shown) such as a spring, and the dustproof cover 3g is placed in the front plate 3e in a state in which the accommodating portion 3 is accommodated in the outer frame portion 2. It is in a state of being pressed to the inner surface side (see FIG. 9 (a)), and intrusion of dust, dust or the like is prevented.
In such a preparation storage case 1, when the dust-proof cover 3g is pushed in with the finger F from the handle hole 3f, the dust-proof cover 3g is pushed up against the pressing force of the elastic mechanism, and the finger F can be inserted (FIG. 9 ( b)).

A method for using the preparation storage case 1 of the present invention will be described with reference to FIGS.
In the preparation storage case 1 of the present invention, the storage portion 3 is usually inserted and stored to the back of the outer frame portion 2 as shown in FIG. When a lateral stress is unexpectedly applied to the housing part 3 due to an earthquake or the like, as shown in FIG. 10 (b), the housing part 3 pops out by the length L1, but the stopper piece A of the housing part 3 there. : The substantially vertical surface 3b of 3a and the stopper piece B of the outer frame portion 2 abut each other.
When taking out the prepared slide stored in the storage section, as shown in FIG. 10 (c), the front side of the storage section 3 is lifted up from the state of FIG. 10 (b) so that the inclined surface 3c of the stopper piece A: 3a If the stopper piece B: 2a is overcome, the accommodating portion 3 can be pulled out to the end as shown in FIG.

In this case, when the pull-out length L1 is long as shown in FIG. 11A, when the front side of the storage portion 3 is lifted to pull out the storage portion 3, it is lifted too much as shown in FIG. Thus, the preparation housed in the housing portion 3 may collide with the opening upper edge 2d of the outer frame portion 2 and be damaged.
In order to avoid this, as shown in FIG. 12A, the estimated insertion length L2 of the finger F to be inserted into the handle hole 3f may be made longer than the pull-out length L1. In this case, when the front side of the housing part 3 is lifted, as shown in FIG. 12 (b), the tip of the finger F touches the upper edge 2d of the opening of the outer frame part 2, so that no further lifting occurs. It is possible to prevent a collision between the preparation and the upper edge 2d of the opening and prevent the preparation from being damaged.

  Further, when the accommodating portion 3 is inserted and accommodated in the outer frame portion 2, the inclined surface 3c of the stopper piece A: 3a of the accommodating portion 3 is simply slid and pushed on the stopper piece B: 2a of the outer frame portion 2. Housed in the outer frame 2.

  As described above, according to the preparation storage case of the present invention, even if a lateral stress is unexpectedly applied due to an earthquake or the like, the stopper piece A of the storage portion 3 and the stopper piece B of the outer frame portion 2 collide with each other. Thus, the housing part can be prevented from jumping out of the outer frame part and falling. In addition, when taking out the prepared slide stored in the storage portion, by pulling while lifting the storage portion, the abutment between the stopper piece A and the stopper piece B is released, and the storage portion can be easily pulled out. Since the storage portion is lifted up a little and can be easily stored by moving the stopper piece A over the stopper piece B, it is useful as a preparation storage case with high safety and ease of use.
