  The present invention relates to a preparation storage case for storing a preparation for microscopic observation in which a thin piece of a biological specimen such as a pathological tissue is fixed. In particular, even when the storage portion is lifted to release the pop-out prevention function, the preparation is performed. It is related with the preparation storage case which can prevent the accident which collides with an outer frame part and is damaged.

  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 preparation prepared as described above is stored and stored in a preparation storage 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 storage case and observed with a microscope.

As a storage case for organizing samples such as embedding blocks and slide glasses (preparations), the present applicant projects a stopper piece A projecting from the bottom surface of the bottom plate of the housing unit and a top surface of the bottom plate of the outer frame. A storage case that can prevent the storage portion storing the slide from unexpectedly jumping out even when there is a roll due to an earthquake or the like by abutting the stopper piece B that has been made has been proposed (Patent Document 1).
In such a storage case, when taking out the preparation in the storage portion, the storage portion is pulled until the stopper piece A and the stopper piece B of the outer frame portion are brought into contact, and then the storage portion is lifted up a little to stop the stopper piece A. An operation is required in which the stopper piece B is moved over and pulled further to pull out the accommodating portion from the outer frame portion and take out the preparation.

  The preparation storage case 1 of the present invention has, as shown in FIGS. 1 to 3, for example, a rectangular-shaped (typically rectangular parallelepiped shape, hereinafter the same) storage portion 2 that is open on one side. A drawer-type preparation storage case 1 inserted into a rectangular outer frame portion 3 having a portion 3a, and a protective sheet 2a of a preparation P is provided on the front wall portion 2b of the storage portion 2 It extends from the upper part of 2b toward the rear wall part, and the protective sheet 2a is flexible.

The outer frame portion 3 used in the present invention is a rectangular box-shaped member that can accommodate the accommodating portion 2 in which the preparation P is accommodated. The outer frame part 3 is provided with an opening 3a on one side, and as shown in FIG. 1, the housing part 2 can be drawn out and put out from the opening 3a.
The accommodating portion 2 is a rectangular box-shaped member that can accommodate the preparation P. The upper portion of the housing portion 2 is opened, and the preparation P can be stored or taken out from the opening.
The preparation P is generally quite small and has a large number, so that usually several elongated accommodating portions 2 are accommodated in one outer frame portion 3 so that they can be easily organized and accommodated. It is configured.

The present invention is particularly suitable for a preparation storage case that is configured so that the housing portion 2 does not jump out even in the case of a roll such as an earthquake, and can release the pop-out preventing function by lifting the housing portion 3.
As a specific example, for example, as shown in FIG. 2, a pop-out prevention mechanism comprising a stopper piece 4 a provided on the bottom plate bottom surface of the housing portion 2 and a stopper piece 4 b provided on the bottom plate top surface of the outer frame portion 3. In addition, there is a preparation storage case in which when the lateral stress is applied to the storage portion 2 due to an earthquake or the like, the stopper piece 4a and the stopper piece 4b collide with each other to prevent the protrusion.
4c is a rear end indicating portion for an alarm mechanism for preventing the accommodating portion 2 from being completely pulled out and falling from the outer frame portion 3 when the accommodating portion 2 is pulled out from the outer frame portion 3. Consists of corrugated protrusions. This rear end indicating portion 4c is just before the housing portion 2 is pulled out from the outer frame portion 3, just before it gets on the stopper piece 4b on the upper surface of the bottom plate of the outer frame portion 3 and the housing portion 2 is pulled out due to rattling and vibration. The alarm is issued to prevent falling.

  It is preferable to provide a handle for facilitating pulling out the housing portion 2 on the front wall portion 2b of the housing portion 2. In the present invention, the shape of the handle is not particularly limited.

A method of using the preparation storage case 1 in which the stopper piece 4a and the stopper piece 4b as described above are provided to prevent the storage portion 2 from popping out will be described with reference to FIG.
In the preparation storage case 1 of the present invention, as shown in FIG. 4A, the storage portion 2 is usually inserted and stored as far as the back of the outer frame portion 3. When a lateral stress is unexpectedly applied to the housing part 2 due to a normal earthquake or the like, the stopper piece 4a of the housing part 2 and the stopper piece 4b of the outer frame part 3 abut against each other, thereby preventing the housing part 2 from popping out. be able to.
When the preparation stored in the storage portion 2 is taken out, as shown in FIG. 4B, the storage portion 2 is slightly pulled out so that the stopper piece 4a of the storage portion 2 and the stopper piece 4b of the outer frame portion 3 are brought into contact with each other. 4 (c), if the front side of the housing part 2 is lifted upward so that the stopper piece 4a gets over the stopper piece 4b, as shown in FIG. 4 (d), The accommodating part 2 can be pulled out to the last. In this example, since the alarm mechanism is provided, an alarm is issued as described above immediately before the housing portion 2 is pulled out to the end, and the housing portion 2 is prevented from falling.

In the preparation storage case as described above, when the front side of the storage portion 2 is lifted to pull out the storage portion 2, the preparation P stored in the storage portion 2 collides with the upper edge 3b of the opening 3a of the outer frame portion 3. However, inconveniences such as an unpleasant collision sound or damage may occur.
In the present invention, in order to avoid such inconvenience, a protective sheet 2 a is provided on the front wall portion 2 b of the housing portion 2. The protective sheet 2a extends from the upper part of the front wall part 2b toward the rear wall part 2f, and is at least part of the upper surface of the preparation P accommodated in the accommodating part 2, that is, the accommodating part 2 When the front side is lifted upward and the engagement between the stopper piece 4a and the stopper piece 4b is released, the preparation P is provided so as to cover at least a portion that collides with the upper edge 3b of the opening of the outer frame portion 2. When the protective sheet 2a is hung downward by its own weight, the protective sheet 2a can be inserted into the outer frame part 3 in a state of being accommodated in the accommodating part 2, so it is preferable to design a little longer. However, it is preferably about 5 to 10 cm. On the other hand, it is preferable that the width of the protective sheet 2a is the same as or slightly larger than the preparation P. Since this protective sheet 2a alleviates the impact, even when the storage part 2 is lifted, the preparation P collides with the upper edge 3b of the opening 3a of the outer frame part 3 and makes an unpleasant sound. The trouble of being damaged is prevented.

Although the protective sheet 2 a can be provided integrally with the housing part 2, it is preferable to form the protective sheet 2 a on the protective sheet 5 separate from the housing part 2. The separate protective sheet 5 is convenient because it can be easily replaced when it is damaged or dirty during use.
Although the form of the protective sheet 5 is not particularly limited, for example, as shown in FIG. 5, the protective sheet 5 has a fixed portion 5 b connected to one end side of the protective portion 5 a that protects the preparation P, and the fixed portion 5 b is accommodated in the accommodating portion. The form which enables it to fix to the 2 front wall part 2b can be illustrated.

  When a partition that divides the inside of the accommodating portion 2 in the width direction is provided, as shown in FIG. 5A, the fixing portion 5b of the protective sheet 5 is provided with a notch 5c straddling the partition. Good. If it does in this way, as shown in FIG.5 (c), since the partition 2e of the accommodating part 2 fits with the notch 5c of the protection sheet 5, the positioning of the protection sheet 5 becomes easy, and also stably. Can be installed. In the example shown in FIG. 5, the number of notches 5c is one, but when there are two or more rows of partitions 2e, the number of notches 5c may be the same as the number of partitions 2e.

  When the fixing portion 5b of the protective sheet 5 is fixed to the inner surface of the front wall portion 2b of the housing portion 2, a fold or a crease 5e is attached to the boundary between the fixing portion 5b and the protective portion 5a so as to be substantially perpendicular or slightly acute. It is preferable that the front end of the bending protection sheet 5 hangs downward. When the crease or the signature 5e is insufficient, the protective sheet 5 jumps upward, and it may be difficult to accommodate the accommodating portion 2 together with the protective sheet 5 in the outer frame portion 3. In order to eliminate such inconvenience, a weight 5d may be provided at the tip of the protective sheet 5 as shown in FIG. These signatures 5e and weights 5d can also be applied to the protective sheet 2a described above. Further, it is also preferable that the fixing portion 5b and the protective sheet 5a are formed in advance approximately perpendicularly or slightly at an acute angle.

  A method of attaching the protective sheet 5 to the housing part 2 is not particularly limited, but a method of attaching the fixing part 5a to the inner surface side of the front wall part 2b using an adhesive or an adhesive is easy. However, in order to facilitate replacement of the protective sheet 5, for example, as shown in FIG. 6A, a pocket portion 2c is provided on the inner surface side of the front wall portion 2b, and the fixing portion 5a is placed in the pocket portion 2c. The method of storing in can be illustrated. Alternatively, for example, as shown in FIG. 6B, a method may be used in which a clip portion 2d is provided on the inner surface side of the front wall portion 2b and the fixing portion 5a is sandwiched between the clip portion 2d and the front wall portion 2b. Further, as a simple method, the fixing portion 5a may be adhesively fixed to the inner surface side of the front wall portion 2a with an adhesive that repeatedly exhibits adhesive force as used for sticky notes.

The material of the protective sheet 2a or the protective sheet 5 is not particularly limited, but is preferably a flexible material or a soft material, and examples thereof include paper, resin, rubber, and nonwoven fabric. Among these, it is particularly preferable to use paper, a soft resin, a foamed resin, or a rubber because it is lightweight and easy to mold and has a sufficient buffering force. Specific examples of resins that can be used in the present invention include polyolefin resins such as polyethylene and polypropylene, vinyl acetate resins, polyurethane resins, ABS resins, AES resins, vinyl chloride resins, polyamide (nylon) resins, polyester resins, and the like. Examples thereof include a plastic resin. Biodegradable plastics such as polylactic acid resin, polybutylene succinate, polyamide 11, polyhydroxybutyric acid, biomass plastics, and the like can also be used. Among these, paper, soft polyethylene, soft vinyl chloride resin, foamed polyurethane sheet, and the like are preferable. Moreover, it is preferable to use a transparent sheet because the slide can be visually recognized from above the protective sheet.
The thickness of the protective sheet 2a or the protective sheet 5 is not particularly limited as long as a sufficient buffering force can be obtained, but is preferably about 0.1 to 2 mm, more preferably about 0.2 to 1 mm. It may be determined in consideration of the above.

  As described above, according to the preparation storage case of the present invention, even when the preparation in the storage portion collides with the outer frame portion, the impact is reduced by the protective sheet, so that unpleasant noise due to the collision is reduced or prevented. In addition, it is possible to prevent the preparation from being damaged. Therefore, it is possible to provide a preparation storage case with high safety.
