Description

[Detailed description of the invention] Industrial use ff! } This improvement is based on improvements in containers for transporting and incinerating large quantities of medical waste, which in many cases includes disposable injectors and 2J devices after use. Although the incineration process is not limited to this, a down-combustion type Batsub furnace is used, which produces a small amount of toxic exhaust gas, has high thermal efficiency, is virtually maintenance-free, and occupies a small amount of furnace space.

Conventional TechnologyDisposable syringes are rapidly gaining popularity and their use is increasing rapidly in large hospitals, as their use is the safest mycologically and in handling for patients as well as nurses and doctors. 10,000 or 20,00 per day
Cases exceeding 00) Rare (no longer available) In many cases,
Local governments that actually process this type of medical waste, including used swords, are in Tokyo, for example! Ward I, Suginami Ward, etc. have many clinics, from small to medium-sized to huge hospitals, and their daily throughput is enormous. However, medical waste, including used disposable copper pouring needles, is not allowed to be buried in the ground or disposed of in rivers, etc., and is simply incinerated completely (however, the metal parts remain, but due to the high temperature, they are not completely destroyed). However, most of the waste is outsourced to subcontractors, and their final disposal methods and responsibilities are difficult to trust. There are many unusual cases where syringes are simply buried underground or disposed of in garbage dumps.An extremely bad example is when a large number of used syringes are found in rivers that flow through areas where citizens live densely. It was not uncommon for cases like this to occur.

Due to these circumstances, local governments have begun to refuse the collection and final disposal of used syringes, etc., and require hospitals to dispose of them on their own. Also,
Yamaguchi Prefecture4 Currently, in Oita Prefecture and other prefectures, local governments collect large amounts of waste and incinerate it in electric furnaces.

Problems of the prior art that Ming attempts to solve In view of the current state of the prior art as described above, the present invention attempts to solve the problems. The problem is that there is no risk that workers handling the used disposable syringes, which are often included in the collection, may be exposed to AIDS, hepatitis, or other dangerous contact-related and blood-borne diseases by touching the tip of the needle. west,
To prevent harmful bacteria from flying into the air, make sure that FFI containers are not opened unnecessarily, or even if they are accidentally opened, a supervisor will immediately discover the accident and promptly open the container appropriately. Transport and incinerate medical waste, which often contains used disposable copper pots that can be disposed of and incinerated in a furnace that avoids the generation of harmful hydrogen chloride gas during incineration. To provide a container for.

Means for Solving Problem 0 As a means for solving the above-mentioned problems, the present invention consists of a lid body and a box body, both of which have a generally rectangular planar shape. The lid and box of the box will not be able to be opened again when they are combined after medical waste has been placed in the box, or if opening is unacceptable. Transporting and incinerating medical waste, characterized in that the lid and box are made of a transparent or translucent resinous composite of cellulose origin. A container for processing is suggested.

DETAILED DESCRIPTION OF THE INVENTION Preferred embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a partially cutaway plan view of the container of the present invention, FIG. 2 is a partially cutaway elevational view, and FIG. 3 is a pressurized container that cannot be reopened. In order to show the structure of the self-fitting platform type female/male joint part, a perspective view of the main part showing only the part including a part of the lid body and box body in an open state is enlarged, No. 4
The figure is a schematic vertical vertical cross-section showing one example of a preferred, non-limiting embodiment of an incinerator capable of incinerating a large number of containers for transporting and incinerating medical waste according to the present invention, along with their contents. It is a diagram.

To explain this in detail, in these figures, A indicates a container according to the present invention, 1 indicates a lid, and 2 indicates a box that fits airtightly with the container, the shape of which is as follows. When viewed in plan, it is roughly rectangular in shape, and the material is transparent or translucent, made of cellulose-based material that emits little or no harmful gases such as hydrogen chloride, nitrogen oxides, and sulfur oxides even when baked. There are some synthetic compounds.

Examples of this type of substance include cellulose 0}i acid,
Nylon, etc., can be mentioned, but there are grips with BUc pressed at appropriate places on the external surface of the material, which are conveniently provided to transport or change the location of the box body A. Not a required component.

The lid rest 1 is particularly shown in the oblique view of FIG.
The combined state with one of the two is shown in FIG. 2 by reference numeral g4. This can be reopened, or, although not shown in the figure, one or both of the female and male can be constructed in a continuous ring shape.
5 maintains airtightness between the lid body 1 and the box body 2 when they are closed, and prevents harmful fungi contained in the medical waste from being accumulated inside the container 8 to the outside. Seal packing to avoid release. In addition, 6G in Figure 2
schematically displays the east coalescence of medical waste. However, its illustration is omitted in other figures.

1 1Q R Tomono sells not only needles but also tubes,
There are various items such as blood bags, ho-tai, cotton wool, etc.

An example of the incinerator B for incinerating the filled container A obtained as described above will be described in detail with reference to FIG. 4.

In FIG. 4, 10 is a furnace body made of heat-resistant concrete or refractory brickwork, and 11 is a lining layer that substantially covers the inner surface of the furnace body. This lining layer 11 is mainly composed of a thermal star-rich material (such as the one completed by the Nagoya Industrial Research Institute) or a composite thereof (such as has been completed by the Nagoya Industrial Research Institute), and contains suitable auxiliaries such as mica powder and inorganic pigments. It consists of a heat-resistant solid layer made by thoroughly kneading a paste or a powdered product with water and drying it.For this molding, it is possible to use a mold or a mold. be.

12 is the hearth, but Rostre is in a state of being a naturalist or similar. In other words, open burning is carried out in a batch manner at a relatively low temperature in a virtually sealed furnace chamber 13, and the moisture content of the waste evaporates before combustion, resulting in a large amount of aqueous Gas is generated automatically in the furnace, and special combustion 11 is not normally required. In order to increase the number of such water-based medical aids, if you put some water in the bottom of the container in advance, this is the most effective effect. It increases exceptionally.

Most of the upper part of the furnace room 13 is constructed in the form of a water-cooled room 14, and the hot water produced by heating the furnace 11 is used for heating, greenhouse cultivation, and other heat sources via piping not shown in the diagram. or the steam vent section 15 and piping 1.
6 can serve the same purpose.

In addition, there is an input port 17 in the top part of the furnace chamber 13, through which a large number of the containers 8 mentioned above are loaded.
You can close it by closing it.

Furthermore, several air intake holes 197'J''R2 are provided in the top part of the furnace chamber 13, penetrating the top and bottom of the furnace chamber 13, through which air for combustion is taken into the furnace chamber 13 from outside. (Although it is not shown in the figure, these air intake ports 19 have K and fltG, which can be adjusted to adjust the depth of each air intake or to close them.) The amount is adjusted according to the combustion temperature.

Usually, the effective volume of the furnace is, for example, 0. 5-10
．． The optimal size is 0m3<3, but in exceptional cases it can be made much larger for uniform use in local governments, etc. In large furnaces, it is possible to measure the temperature inside the furnace with something like a pipe meter, and use the results to control all air intakes electrically.

There is. The flue 20 is provided with at least one air intake port 19, and between the flue 20 and the chimney 2, O', noxious gases and aqueous gas rising from the furnace are removed. It is truly amazing that the amount of smoke emitted outside is extremely small, and the exhaust gas is almost clean and transparent. There are no complaints from anyone. This has already been confirmed by experiment. In addition, a large number of containers A charged with contents are lined up in a row at the bottom of the furnace, and at the same time, the furnace and containers A
They are arranged in 2 to 5 stages depending on the size. Although not shown in the figure, a dust removal wire mesh may be placed at the upper end of the chimney 21.

To use the above-mentioned furnace, place a group of eight containers whose contents have been charged as described above in the furnace, place some flammable materials such as dead branches or pieces of cardboard on top of the containers, and open the inlet port 1.
7 or the air intake port 19, the flame starts to ignite and then automatically burns gradually from the upper part to the lower part in a descending manner. If necessary, place a small piece of cardboard between containers A and A from the beginning to prevent the fire from going out.

Combustion follows the principle of wildfire burning automatically, without the addition of expensive special fuels such as oil, coal, or gas, and automatically via gasification in a virtually closed room without lossttle. Because it progresses from the upper layer downwards (however,
The flame goes upward}, which is extremely efficient. The combustion noise is almost unnoticeable from the outside, and one batch of combustion can be completed in 8 to 24 hours depending on the size of the furnace and the degree of power adjustment. Finally, there is some residual force in the copper pouring needle itself and some other metals, so all you have to do is open the inlet 17 and enter the furnace to clean it. It happens about once a month.

Incidentally, the part of the furnace that is exposed above the ground is smaller than the ground surface GL, making it extremely simple, but if necessary, the incineration work can be done even if the furnace bottom FB is aligned with the ground surface GL and the part exposed above the ground is increased. can.

The temperature inside the furnace is preferably about 900°C to 1200°C, but it may be outside this range if necessary.

Effects of the Invention The present invention has a unique structure to produce a large number of extremely safe containers containing medical waste including injection needles. First, since the incineration is carried out in a special furnace that is closed and uses that principle with high thermal efficiency, there is virtually no danger of workers coming into contact with blood, and the cost of incineration is extremely low. It is an economical and maintenance-free method compared to using an electric furnace or putting several pieces at a time into an incinerator equipped with a roaster through the door and burning them at high temperature while emitting smoke. Can be done. That is, especially in the present invention, no human intervention is required once the ignition has been completed.

After the lid 1 and the box 2 are assembled as described above, duct tape or similar adhesive tape is wrapped in a headband shape around the outer periphery of the container 8 in the area where the seal packing 5 is visible from the outside. If a relatively large inspection mark of an authorized medical waste disposal manager is stamped or affixed at a fixed position between the winding layers or between the adhesive tape and the box body 2, the lid body may be illegally broken. Plans or actions to dispose of the contents in a dangerous manner, such as burying them in the ground, can be discovered.

Of course, although the gist of the invention is to use a male/female joint as described above, it is also possible to use a structure similar to the one described above as a simple means. Therefore, in this case, the adhesive tape that wraps around the container 8 is the {Qth point of the joint between the lid 1 and the box 2.
