Description

[Detailed description of the invention] <Industrial application field> The present invention is a sterilization basket for sterilizing medical equipment such as syringes and needles, microbial culture solutions, and other items using a sterilizer. Regarding.

<<Prior Art>> As is known, when sterilizing various objects to be sterilized as described above, a sterilizer a as shown in FIG. 4 is used.

In order to sterilize the culture solution for bacterial propagation, which is the object to be sterilized, using the sterilizer a, as shown in Fig. 5, a plurality of synthetic resin shears b containing the culture solution are stacked as required. In this condition, put it in a sterilization basket c as shown in Fig. 6 or a sterilization can d as shown in Fig. 7, place it on the cage f inside the main body e of the sterilizer a, and then put the main body e into the lid body. After sealing with g, the water i is heated with a heater h to sterilize the bacteria in the culture solution.

<<Problem to be solved by the invention>> However, if the shear rail b is a disposable plastic product as described above, it may be deformed by the heat during sterilization, or if it is a glass product. In some cases, due to irregular stacking during handling, the dissolved culture solution may leak from the shear tray b into the sterilization basket c or the sterilization can d.

As a result, in the above-mentioned sterilization basket c, the dissolved culture solution flows into the device main body e through the mesh, and further flows down into the device main body e, clogging the drain pipe j or preventing the safety device from operating. The items that can be sterilized are limited because the sterilization basket c becomes dangerous because it is left empty, and small objects to be sterilized, such as syringe needles, may fly out of the mesh of the sterilization basket c. It happens.

Furthermore, in the case of small objects to be sterilized such as injection needles, the above-mentioned sterilization basket c
However, in this case as well, the sterile basket C
In this case, the needle tip may protrude from the processing bag or become detached from the tear, resulting in the same problem as described above.

On the other hand, when the above-mentioned sterilization can d is used, the air does not circulate sufficiently inside the can due to its completely non-porous structure, and the temperature does not rise easily to the inside, resulting in insufficient uniformity of the temperature rise, which may result in poor sterilization. In addition, the sterilization can itself is quite heavy, making it difficult for women to handle it. Therefore, it is necessary to transfer the objects to be sterilized to a separate basket or the like, carry this to the appropriate place, and then discharge the culture medium and the like from the sterilization can, which is a double effort and results in poor workability.

The present invention was developed in view of the above-mentioned problems of the prior art, and the range of objects that can be sterilized is limited by arranging perforated parts and non-porous parts at appropriate locations. It is possible to reliably sterilize a large number of various objects to be sterilized at once without storing them, and the culture solution does not inadvertently flow out, and the culture solution can be disposed of conveniently. The objective is to provide a lightweight sterilization basket.

《Means for solving the problem》 In order to achieve the above-mentioned purpose, the present invention
and has a bottomed shape, and includes a lower end part of the range including the bottom wall side peripheral wall part from the bottom wall to the required height of the peripheral wall, and a required width range in the circumferential direction from the upper end to the lower end part on one side of the peripheral wall. It is intended to provide a sterilization basket in which the peripheral wall is formed as a non-porous portion, and the other peripheral wall portion is formed as a perforated portion having a group of small holes of a required size.

<<Operation>> A required number of shear trays containing the material to be sterilized, which is a culture solution, are stored in the sterilization basket in a stacked state, and the same basket is placed on the screen in the main body of the sterilizer. and then seal the main body of the device with the lid.

Next, the heater is energized, and the water contained in the main body of the apparatus is heated by the heat generated from the heater.

This will cause the inside of the above device to reach the required temperature (for example, 121°C).
℃), the inside of the basket becomes uniformly high temperature through the large number of small holes in the peripheral wall and the opening at the upper end, whereby the objects to be sterilized are sterilized.

Additionally, when the synthetic resin shear tray is thermally deformed during the sterilization process, the culture solution will flow out, but since the culture solution is stored in the lower end of the basket, it will not flow into the main body of the device. Nor.

After sterilization, the basket is removed from the device body after cooling and the materials to be sterilized, such as the culture solution, are disposed of. By tilting the basket so that the non-porous part provided in the section is on the lower side, the non-porous part serves as a gutter and the water can flow out without any problem.

<<Example>> The present invention will be described below with reference to an illustrated example.

As shown in FIGS. 1 to 3, the basket body 1 is a vertically elongated cylinder having a required inner diameter and height such that a required plurality of shears, etc. (not shown) can be stacked inside. Shape it,
It has a bottom, and an opening 2 is formed at the upper end.

Further, the basket body 1 has a bottom wall 3
Not only is the lower part of the peripheral wall 4 formed as a non-porous part, that is, the bottom wall side peripheral wall part 4a that is within a required height H (for example, 50 mm) from the bottom wall 3, also non-porous. Therefore, the required amount of culture solution etc. can be stored in the lower end portion 5 consisting of the bottom wall 3 and the bottom wall side peripheral wall portion 4a of the basket main body 1.

Further, a non-porous portion 4b is formed in one side band of the peripheral wall 4 from its upper end to its lower end and within a range of a required width l in the circumferential direction.

In other words, the non-porous portion 4b has its lower end connected to the upper edge of one side of the bottom wall side peripheral wall portion 4a of the lower end portion 5, which is the non-porous portion.

The peripheral wall 4 other than the lower end part 5 which is the non-porous part and the non-porous part 4b of one side band has a required dimension (for example, 5 mm).
The perforated portion 4c is formed by passing through a large number of small holes 4d having a diameter of about 100 mm.

Further, for ease of handling, the basket body 1 can be formed of a light metal such as aluminum by press working or die casting, or by joining light metal plates using a joining means suitable for the material.

The non-porous part 4b in one side band of the peripheral wall 4 has a width in the circumferential direction so as to be in the shape of a gutter so that it is convenient to dispose of the culture solution, water, etc. accumulated at the bottom of the bucket main body 1. l is preset and formed to a required dimension.

Further, the basket body 1 can be formed to have a perfect circular cross section, a circular cross section as in the illustrated example, or any other polygonal shape, but when it is formed into an elliptical cross section, its peripheral wall 4 If the non-porous part 4b of one side band is formed on the long diameter side as shown in Fig. 2, or on the corner side when the cross section is polygonal, the width l in the circumferential direction can be formed relatively small. It is also convenient for releasing culture medium and water.

Further, it is practically desirable that the non-porous portion 4b has an area approximately 1/4 of the entire circumference of the peripheral wall 4 of the bucket main body 1.

In FIGS. 1 and 3, reference numeral 6 indicates a handle pivotally supported in the opening 2 of the basket body 1.

<<Effects of the invention>> Since the present invention is constructed as explained above, a large number of small holes are provided in the peripheral wall other than the lower end part and one side part, so that air circulation is improved. If the temperature is good, the internal temperature will rise sufficiently and uniformly, and therefore the sterilization process will proceed satisfactorily and efficiently, and the lower end base will be formed as a non-porous part. Since the culture solution, which is a dissolved medium, accumulates at the bottom and does not flow out into the sterilizer, it is possible to avoid the inadvertent non-operation of the device due to clogging of the drain pipe by the medium. You can also
Since injection needles and small objects to be sterilized do not protrude from the bottom wall, the objects to be sterilized are not limited.
It becomes possible to process a wide variety of items.

In addition, by tilting the non-porous part on one side of the peripheral wall with the bottom side, it can act as a gutter, allowing the culture solution, water, etc. accumulated in the lower end vessel to leak out along the non-porous part. It can be disposed of without spilling out through the opening.
