Examples will be shown below to describe the medical material storage case of the present invention in more detail.

[0013]

1 is a sectional view showing an example of a medical material storage case of the present invention, and FIG. 2 is an exploded perspective view thereof. For example, as illustrated in FIG. 1 and FIG. 2, the medical material storage case of the present invention has a material storage chamber (2) for accommodating the medical material (1) or a case in which the medical material is loaded. A second moisture-proof case (6) for shielding the outside world, which has a first moisture-proof case (3) and a desiccant storage chamber (5) for storing the desiccant (4) adjacent to the material storage chamber (2), material storage A sterilizing gas-permeable sterilizing sheet (7), which is disposed between the chamber (2) and the desiccant storage chamber (5) and closes the opening for storing the medical material of the first moisture-proof case (3). And a second moisture-proof case (6)
And a moisture resistant sheet (8) for closing the opening of the.

In this example, the first moisture resistant case (3) and the second moisture resistant case (6) are integrally molded. The sterilization sheet (7) has its periphery attached to the stepped portion (9) of the opening of the first moisture resistant case (3),
The opening is closed. Further, the moisture resistant sheet (8) is configured such that its peripheral edge is adhered to the flange portion (10) of the opening of the second moisture resistant case (6) and the opening is closed.

For example, in the above-mentioned structure, the first moisture-resistant case (3) and the second moisture-resistant case (6) having the storage chamber (2) for storing the medical material (1) or the case inserter thereof. The case body made of can be formed of various moisture-resistant materials such as polyester, polyolefin, polyvinyl chloride and its fluorine-substituted products, polyvinylidene chloride and its fluorine-substituted products, or their laminated films and laminated films. The laminated film or laminated film may include a metal layer such as aluminum. Further, the moisture resistant sheet (8) for closing the opening of the second moisture resistant case (6) can also be appropriately constituted by these materials similarly.

The case body composed of the first moisture-proof case (3) and the second moisture-proof case (6) and the moisture-proof sheet (8) may be made of either a transparent material or a colored material. When using a transparent material, it is possible to check the inside of the case, and when using a colored material, it is possible to prevent light deterioration and the like. In consideration of the type of medical material to be enclosed and stored, the state of storage, etc., an appropriate material can be selected and used from the various materials described above.

Second moisture-proof case (6) and moisture-proof sheet (8)
Means that the material is attached so that it can be heat-sealed, or that the adhesive layer is provided on both sides or on one side. When the adhesive layer is provided, it is formed of a material having good moisture resistance, and for example, a urethane seal material, an acrylic seal material, or the like is used.

The sterilization sheet (7) interposed between the first moisture-proof case (3) and the second moisture-proof case (6) is permeable to a sterilizing gas, such as ethylene oxide gas, and contains bacteria. Use the one that does not pass through. Various materials can be used as the material, and a general sterilization sheet may be used depending on the case. This sterilization sheet (3) also has heat sealability or adhesiveness so that it can be attached to the stepped portion (9) of the first moisture resistant case (3).

The desiccant (4) is also not particularly limited in its type, shape and the like. An appropriate shape such as a granular shape, a small piece shape, or a bulk shape can be used, and as shown in FIGS. 1 and 2, it may be contained in a bag or the like. The one placed in a bag or the like is preferable because the drug is not dispersed therein.
The desiccant (4) is stored in a space separated from the material storage chamber (2) and is shielded by the sterilization sheet (7). It does not contaminate the medical material with powder or the like generated from the desiccant.

Further, as shown in FIG. 1, the desiccant (4)
May be put in a bag and the bag body may be attached to the moisture resistant sheet (8) in advance. The medical material storage case of the present invention exemplified as such a structure and material will be described as an operation of storing and taking out the case, for example. Storage As is clear from FIGS. 1 and 2, the medical material (1) is placed in the material storage chamber (2) of the first moisture resistant case (3). The sterilization sheet (7) is attached and attached to the stepped portion (9) at the periphery thereof. Then, in this state, it is put into a pot and subjected to heat sterilization treatment using a sterilizing gas.

After the sterilization treatment, the second moisture resistant case (6)
The desiccant (4) is put in the desiccant storage chamber (5), and the moisture resistant sheet (8) is attached to the flange portion (10) at the periphery thereof. In this way, the storage of the medical material (1) in the storage case is completed. At the time of extraction surgery, the doctor first peels or tears the moisture resistant sheet (8) and removes the desiccant (4). Next, the sterilization sheet (7) is peeled off or torn, and the medical material (1) is taken out from the material storage chamber (2).

As described above, the storage and storage of the medical material and the taking out of the medical material are extremely easy. Of course, without being limited to the above example, various specifications are specifically adopted for the medical material storage case of the present invention. For example, although FIGS. 1 and 2 show a case body having a first moisture resistant case (3) and a second moisture resistant case (6) in a rectangular shape,
This may have a square shape or a round shape as shown in FIG. It may have any other shape.

The material storage chamber (2) or the entire case can be adapted to the shape of the medical material. In this case, it is possible to prevent the medical material from moving during transportation. Further, the first moisture resistant case (3) and the second moisture resistant case (6) are
As illustrated in FIG. 4, it may be formed as a separate body and connected by a screw connection (11). The part and method for the screw connection (11) can be appropriately determined. In addition to such a screw connection (11), for example, as illustrated in FIG. 5, the first moisture resistant case (3) and the second moisture resistant case (6) are integrated by a connection by a fitting connection (12). It is also possible to make it.

Even in the case of such a separate structure, it is necessary that the sterilization seal (7) is adhered so that the airtightness is perfect, and the connection structure is not required during transportation and storage. It is also necessary to make the case more rigid so that it does not collapse. Regarding the medical material (1), in the above example, the material is stored in the material storage chamber (2) as it is, but depending on the type, as shown in FIG. 6, a suitable material such as glass or resin is used. A medical material (1) such as an artificial tooth root is put in a case (13) made of a raw material, and the medical material (1)
It is also possible to put the case (13) charged with the material into the material storage chamber (2) as it is. The case (13) can also be sterilized by gas, and the case (13) also allows the medical material to be kept hollow.

It goes without saying that the storage case of the present invention has various modes other than the above examples.

[0026]

According to the present invention, the following excellent effects can be obtained. It is possible to package and take out the material much easier than the conventional case where the medical material contained in a bag or the like is gas sterilized and then placed in a moisture resistant bag or a moisture resistant container for multiple packaging storage.

The inside can be confirmed by using a transparent material for the case. By forming the medical material storage chamber into a shape suitable for the material, the medical material does not move during transportation. Since it has been sterilized, it is not necessary to sterilize it in advance at the time of surgery, and it is possible to change the material used during an emergency or during surgery.

It is also possible to put the medical material in a separate container (which can be sterilized) and keep it in a hollow state so as not to directly contact the case of the present invention. A desiccant keeps the case dry for a long time. Since the desiccant and medical materials are stored in different rooms,
The medical material is not contaminated by the substance such as the desiccant or the powder generated from the desiccant.

After the sterilization process, to store the desiccant,
No reduction in potency of desiccant due to sterilization.
