Abstract
Description
Technical Field
[0001] The present application relates to the technical field of sterilization equipment, and in particular to a high-pressure sterilization box. Background Art
[0002] At present, institutions such as high-level pathogenic microorganism laboratories often place small materials that need high-pressure sterilization in small stainless steel sterilization boxes such as 1.8L or smaller. Because the sterilization box is small, steam can easily penetrate the covered sterilization box through the gaps under high pressure. Large items are placed in a fully enclosed larger stainless steel sterilization box. It is difficult for steam to penetrate the larger stainless steel sterilization box through the gaps under high pressure, and the sterilization effect cannot be achieved; and water vapor is often retained in the sterilization box during the sterilization process, causing the high-pressure items to become wet after the high pressure is completed.
[0003] Therefore, for large items, disposable sterilization breathing bags, medical sterilization packaging non-woven fabrics and other packaging materials are often used to package, autoclave and store the materials to be sterilized. However, disposable sterilization breathing bags, medical sterilization packaging non-woven fabrics and other materials have the following problems:
[0004] First, the use cost is high. The above materials are all disposable and non-reusable packaging materials. However, institutions such as high-level pathogenic microorganism laboratories require a large number of materials for disinfection and sterilization, and the frequency of disinfection and sterilization is high. The cost of using disposable sterilized breathing bags and other packaging materials is high.
[0005] Second: Disposable sterilized breathing bags, medical sterilized packaging non-woven fabrics and other packaging materials cannot be reused, which is not conducive to environmental protection;
[0006] Third: The mechanical strength is lower than that of stainless steel products. During the transportation and storage of materials after sterilization, there is a risk of damage to the outer packaging due to accidents such as falling and squeezing, and the sterilized materials may be contaminated again.
[0007] Therefore, it is urgent to provide a high pressure sterilization box to solve the technical problems raised above. Utility Model Content
[0008] Based on this, a high-pressure sterilization box is provided, which can be suitable for the sterilization and storage of large items, and can be placed in a double-door high-pressure sterilizer for repeated use, which can save costs. At the same time, the surface is sturdy and not easy to be damaged, avoiding the situation where the high-pressure sterilization materials are damaged due to the outer packaging during transportation and storage, and the sterile materials are contaminated again.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0029] The embodiment of the present application provides a high-pressure sterilization box. In order to reduce the cost of high-pressure sterilization work and reduce the use of disposable items, a stainless steel container with a large volume suitable for sterilization and storage of large items is modified to make it suitable for both high-pressure sterilization and transportation and storage of sterilized items.
[0030] A high-pressure sterilization box provided in this embodiment is described in detail below. The high-pressure sterilization box is applied to a double-door high-pressure sterilizer. When in use, the materials to be sterilized are placed in the high-pressure sterilization box before high pressure, and then the high-pressure sterilization box is placed in the double-door high-pressure sterilizer. After the high-pressure sterilization program of the double-door high-pressure sterilizer is completed, the double-door high-pressure sterilizer is opened, and the high-pressure sterilization box and the sterilized materials contained therein can be transported and stored to a suitable place for standby use.
[0031] Please refer to Figure 1-Figure 3 As shown, the high-pressure sterilization box includes: a box body 1, a box cover 2 and a closing plate 3. The box cover 2 is used in conjunction with the box body 1. The box cover 2 seals the box body 1 or the material to be sterilized can be placed in the box body 1 after it is opened; the front wall 11 and the rear wall 12 of the box body 1 are respectively provided with a ventilation area 13, and the steam airflow of the double-door high-pressure sterilizer can pass through the ventilation area 13 to reach the interior of the box body 1, and then the material to be sterilized is sterilized under high pressure; the closing plate 3 is respectively arranged at the position of the front wall 11 and the rear wall 12, and is used to close or open the ventilation area 13.
[0032] In this embodiment, air permeable areas 13 are respectively provided on the front wall 11 and the rear wall 12 of the box body 1. The air permeable area 13 is designed to make steam permeability stronger, the sterilization effect is excellent, and the air permeability is good, which is not easy to cause water vapor retention and moisture of the sterilized materials after the sterilization is completed. At the same time, after the double-door high-pressure sterilizer is opened at the end of sterilization, the closing plates 3 of the front wall 11 and the rear wall 12 are quickly closed to ensure the sterile storage of the sterilized materials. The air permeable area 13 is controllable, and then the high-pressure sterilization box in this embodiment and the sterilized materials contained therein can be transported and stored to a suitable place for standby use. The appearance is firm and not easy to be damaged, which can avoid the situation where the outer packaging of the high-pressure sterilized materials is damaged during transportation and storage, and the sterile materials are not contaminated again.
[0033] Please continue to refer to Figure 1-Figure 3 As shown, in this embodiment, it should be noted that the ventilation area 13 includes a plurality of ventilation holes 131 arranged on the front wall 11 or the rear wall 12, and the plurality of ventilation holes 131 are distributed in a grid shape. Through the ventilation holes 131 on the front wall 11 and the rear wall 12 are distributed in a grid shape, the steam airflow can flow into the interior of the box body 1 faster and more evenly, thereby achieving high-temperature sterilization of the materials to be sterilized inside. In addition, the diagonal arrangement of the front and rear ventilation areas enables the steam airflow to form a uniform airflow organization inside the high-pressure sterilization box when passing through the front and rear walls, and form a good circulation, avoiding dead corners that steam cannot reach, and ensuring the sterilization effect.
[0034] In one example, the area of the ventilation zone 13 should not be too large or too small. If the area of the ventilation zone 13 is too large, the risk of contamination of the sterile material will increase when the ventilation zone 13 is quickly closed after the high-pressure sterilization is completed; if the area of the ventilation zone 13 is too small, the efficiency of hot steam penetrating the sterilized material will be reduced, thereby reducing the sterilization efficiency. Therefore, in this embodiment, the area occupied by the ventilation zone 13 is selected to be 20-25% of the area of the front wall 11 or the rear wall 12. In addition, it should be noted that in order to make the steam airflow pass through the ventilation zone 13 to form a relatively uniform and complete airflow organization in the box body 1, and form a good circulation, avoid dead corners that steam cannot reach, and ensure the sterilization effect, the position of the ventilation zone 13 should meet the following two conditions: first, the positions of the ventilation zones 13 on the front wall 11 and the rear wall 12 are diagonally arranged, in other words, the positions of the ventilation zones 13 on the front wall 11 and the ventilation zones 13 on the rear wall 12 are staggered with each other; second, the height of the ventilation zone 13 is located in the middle of the height of the front wall 11 or the rear wall 12.
[0035] Please continue to refer to Figure 1-Figure 3 As shown, in this embodiment, it should be noted that, in order to facilitate the use of the closing plate 3, the closing plate 3 is slidably arranged on the front wall 11 or the rear wall 12. Therefore, when the ventilating area 13 needs to be opened, it is only necessary to manually slide the closing plate 3, which is simple to operate.
[0036] In one example, the front wall 11 or the rear wall 12 is provided with slideways 4 at the position of the ventilating area 13, and the slideways 4 are located at the upper and lower sides of the ventilating area 13, that is, the upper side of the upper edge and the lower side of the lower edge of the ventilating area 13 are provided with protruding slideways 4, and the closing plate 3 is slidably arranged on the slideways 4 transversely. The setting of the slideways 4 can ensure that the closing plate 3 is closely fitted with the front wall 11 or the rear wall 12 of the box body 1 when sliding, so that the closing plate 3 can be switched back and forth along the extension direction of the slideways 4, and then the opening or closing operation of the ventilating area 13 is realized.
[0037] It should also be noted that the area of the closing plate 3 is slightly larger than the area of the air permeable area 13, so that it can be ensured that the closing plate 3 can completely close the air permeable area 13 without air leakage.
[0038] In this embodiment, it should be noted that first lifting parts 14 are provided on both sides of the box body 1, and a second lifting part 21 is provided on the top of the box cover 2. Preferably, the first lifting part 14 and the second lifting part 21 are both made of stainless steel. The first lifting part 14 and the second lifting part 21 are provided to facilitate the operator to extract the box body 1 during the transfer process, saving time and effort.
[0039] In one example, the first lifting portion 14 and the second lifting portion 21 are both configured as handles, which facilitate extraction of the high-pressure sterilization box.
[0040] It should also be noted that the box body 1 and the box cover 2 are both made of stainless steel. The box body 1 and the box cover 2 made of stainless steel are resistant to high pressure and have high strength, are not easy to be damaged, and have a long service life.
[0041] The implementation principle of this embodiment is as follows: first, the items to be treated with high pressure, such as reusable cleaned protective clothing, protective shoes, etc., are placed in the box body 1 of the high pressure sterilization box, and the box cover 2 is tightly closed. Then, the closing plate 3 is slid to open the ventilation area 13 on the side, and the items are placed in the double-door high pressure sterilizer. When the high pressure sterilization program is completed, the double-door high pressure sterilizer is opened and the closing plate 3 is quickly slid and closed to block the ventilation area 13 to ensure the sterile storage of the sterilized materials. The sterilized materials are transported and stored in an appropriate place. When the sterilized materials are used up, the high pressure sterilization box can be reused again.
[0042] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
