Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a closed type disinfection storage tank for storing medical instruments, gauze, etc. Currently, the storage tank (Kast) is made by putting medical scalpels, tweezers, gauze, etc. into the storage tank, sterilizing and disinfecting each part in a sterilizer, and then storing the disinfectant in the storage tank until the next use. We have a way to store it.
However, the structure of conventional storage tank irons was an open type in which the iron container itself was provided with an entry hole for steam, gas, etc. to be sterilized with steam or gas. Therefore, even after disinfection, there is a problem in that germs can invade the inside of the iron during storage and contaminate the stored disinfectant. Therefore, a storage tank iron called filter cast has recently been proposed as an alternative to this.

However, this device also has insufficient airtightness at the joint between the main body and the lid, and the filter has a mesh of micropores of about 0.3 microns to allow steam to pass through.
Bacteria such as viruses can pass through gaps as small as 0.01 microns, which contaminates the disinfectant and makes it completely ineffective as a filter. The present invention has been made for the purpose of solving the above-mentioned difficulties and providing a perfect disinfectant storage tank that is not contaminated with germs even after disinfection. The gist of the present invention relates to a closed type sterilization storage tank chisel, which has a storage tank chisel formed in an airtight manner, and a heat-sensitive valve is provided on the lid and the bottom of the chisel body, and the heat-sensitive valve is opened and closed depending on the rise and fall of a certain temperature. It is something.

An embodiment of the present invention will be illustrated and explained below. In the figure, reference numeral 1 denotes an iron container body of a storage tank iron, which has a stepped portion 8 connected to a lid 2 on its upper part, and an edge 4 bent inward to form a flat surface. Reference numeral 5 denotes a packing interposed at the joint between the chisel main body 1 and the lid 2 to airtightly seal the joint between the chisel main body and the lid. 6 is the hinge attached to the lid 2, 7
is a punch lock. Reference numeral 8 designates a heat-sensitive valve mounting portion which protrudes outward from the central portion of the lid 2, and 9 designates a window hole provided in the mounting portion. 10 is a bimetal heat-sensitive valve fixed to the mounting part, and 11 is a valve part. Note that the heat-sensitive valve may be made of a spring or other valve body other than the bimetal of the embodiment. 12 is a gasket attached to the valve portion. 13
is a partition plate that separates the bimetal mounting part and the iron body,
14 is a window hole provided in a ring in the partition plate. Reference numeral 15 designates a mounting portion for a heat-sensitive valve provided in an inwardly convex manner at the bottom of the iron body, 16 designates a bimetallic valve portion, and 17 designates a bimetallic valve portion. 1
8 is a bimetal mounting bottom plate, 19 is a window hole provided in a ring in the mounting bottom plate, 20 is a stepped portion bent into a concave shape in the mounting portion, and 21 is a bimetallic valve hole. 22 is Patsukin. 23 is a partition plate that partitions the inside of the chisel and the valve part, 24 is a window hole, and 25 is a leg. In the storage tank chisel constructed in this way, the lid and chisel body are hermetically sealed with a gasket 5 and a punch lock 7 that is tightened. Further, the valve body portion provided with the window hole is brought into close contact with the lid portion and the bottom of the chisel body by gaskets 12 and 22 to keep the inside of the chisel body airtight. The bimetal that becomes the valve body is approximately 50℃~60℃
℃ so that the valve part expands and separates from the lid and the bottom plate of the iron body. is formed in a state of circulation.

The present invention takes care of such structural effects, so when steam sterilizing medical instruments, gauze, etc., the disinfectant is sealed in the iron body and the pressure is 1.5 kgm ³ ~ in the sterilizer (box).
3.5Kgm ³ and heat under pressure for 15 to 30 minutes at a temperature of 110℃ to 200℃. Therefore, as mentioned above, as the temperature rises due to the action of the heat-sensitive valve (bimetal), the stored items are sufficiently sterilized by the steam that enters the iron body through the valve portion. Then, after sterilization, the pressure is reduced to a vacuum state for about 15 to 20 minutes in a heated state to release the moisture attached to the sterilized material to the outside of the sterilizer, and after it is sufficiently dried, the temperature is lowered and the sterilized body is sealed by the valve action of the bimetallic material. do. Therefore, the iron body becomes an airtightly sealed storage tank and is stored in an intact state until it is used.

In the case of gas sterilization, the gas is heated under normal pressure to sterilize and sterilize. The drying process is the same as in the case of steam sterilization described above.

As mentioned above, unlike conventional open-type storage tanks or filter casts, the present invention has a structure that takes into consideration airtightness to prevent bacteria from entering the storage tank and contaminating instruments such as scalpels and gauze even after sterilization. It can be stored in sterile conditions for a long time, making it a great contribution to medical treatment.
