Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a medical device disposal container for storing medical device waste such as used needles to be disposed of in hospitals.

[0002]

[Prior art]

 Used medical device waste such as injection needles generated in hospitals is discarded and collected in a dedicated disposal container. When waste accumulates in the waste container, the container is sealed, and the container containing the waste is usually transported to an incineration facility where the waste is incinerated with the container. . Conventionally, as a dedicated disposal container for storing medical device waste, a box-shaped container molded of a hard plastic material such as polyester has been most widely used. Recently, double-walled cardboard boxes have been used as disposal containers.

[0003]

[Problems to be solved by the invention]

 However, a box-shaped container formed of a plastic material has an internal volume of, for example, 20 liters and weighs about 1 kg. When an injection needle or the like is contained therein, the total weight is 3.5 kg to 3 kg on average. It will be about 0.8 kg. For this reason, labor is required to transport containers to the incineration facility. In addition, conventional plastic-molded box-shaped containers have the problem that a large amount of heat and carbon dioxide gas are generated when incinerated.

[0004] Furthermore, the cardboard box having the double structure has a concern that the injection needle penetrates the cardboard and protrudes to the outer surface of the box. If chemicals remain, they may also seep out to the outer surface of the cardboard box. Furthermore, it may be damaged by the impact force such as dropping, and the waste stored inside may be exposed.

[0005] The present invention has been made in view of the above circumstances, and is relatively lightweight, has a relatively small amount of heat and waste gas generated at the time of incineration. Provide a medical device disposal container that has no risk of liquid oozing out of the container to the outer surface of the container, and that does not expose the internal medical device waste to the outside of the container even when subjected to impact. The purpose is to:

[0006]

[Means for Solving the Problems]

 The device according to claim 1, wherein the medical device is formed from a sheet-like plastic material into a box shape having a charging opening and a closing lid for closing the charging opening integrally formed. The inner box for receiving the waste, closing the charging opening with the closing lid and sealing the medical device waste, and the cardboard having waterproofness have a size and a shape in which the inner box is completely accommodated. A medical device disposal container is constituted by an outer box formed in a box shape and enclosing and sealing the inner box.

According to a second aspect of the present invention, in the container according to the first aspect, the bottom of the inner box and the closing lid are each formed of a double structure of a sheet-like plastic material, and the constituent sheets of the closing lid are connected to each other. It is characterized by being stopped.

In the medical device disposal container according to the first aspect of the present invention, since the inner box is formed of a sheet-like plastic material, there is no fear that the injection needle contained in the container protrudes to the outer surface of the container. In addition, medical device waste such as injection needles is sealed in an inner box made of a sheet-shaped plastic material, and the inner box is enclosed in an outer box made of corrugated cardboard having waterproofness, and the outer box is sealed. Therefore, there is no danger that liquids such as blood and chemicals remaining in the waste housed therein will seep out to the outer surface of the container. Since this container is made of a sheet-like plastic material and waterproof corrugated cardboard, it is relatively lightweight, and the amount of heat and waste gas generated when incinerated is relatively small. Furthermore, this container has a double packaging form of an inner box and an outer box, so that there is no fear that the waste inside will be exposed to the outside of the container even if it receives an impact such as dropping.

The container according to the second aspect of the present invention is robust because the bottom of the inner box and the closing lid have a double structure of a sheet-like plastic material, and the constituent sheets of the closing lid are mutually connected. Because it is locked, there is no danger of damage or opening of the closing lid even if it receives a shock such as dropping.

The unfolded sheet material 14 shown in FIG. 3 is bent at each of the folds 34 indicated by broken lines, and the heat-welded portion 24 is heat-welded to the component sheet surface 16a to be assembled into a box shape. Then, the component sheet piece 22c is superimposed on the component sheet piece 22a constituting the bottom portion, and both ears of the insertion tongue piece 30a of the component sheet piece 22c are inserted into the respective insertion cuts 32a of the component sheet piece 22a. The bottom surface is closed by locking the sheet pieces 22a and 22c with each other. Further, the constituent sheet piece 22b is superimposed on the constituent sheet pieces 22a and 22c, the constituent sheet piece 22d is superimposed on the constituent sheet piece 22b, and both side ears of the tongue piece 30b for inserting the constituent sheet piece 22d are formed. By inserting each of the component sheet pieces 22b and 22d into each of the insertion cuts 32b of the piece 22b and locking the two component sheet pieces 22b and 22d to each other, the bottom portion has a double structure and is completely sealed. The inner volume of the inner box 10 is, for example, about 18 liters.

In the above-described embodiment, when assembling the inner box 10 from the unfolded sheet material 14, the heat-welded portion 24 is heat-welded to the constituent sheet surface 16a. The method is not limited to heat welding, and may be adhesion with an adhesive, adhesion with an adhesive sheet, or the like. Further, as means for locking the constituent sheet pieces 22a to 22d and 18a to 18d constituting the bottom of the inner box 10 and the closing lid part 20, insertion tongue pieces 26a, 26b having a shape as shown in the illustrated example are used. Not only the method using 30a, 30b and the insertion notches 28a, 28b, 32a, 32b, but also various locking methods can be adopted. For example, a locking method called hell stopper can be used.

The inner box 10 is inserted into the outer box 12 with the bottom closed and the top open as described above. At this time, each of the constituent sheet pieces 18a to 18d (see FIG. 3) constituting the closing lid part 20 of the inner box 10 is folded back in four directions together with the respective cardboard pieces constituting the lid part of the outer box 12, It is fixed on the side of the outer box 12 by hanging a rubber belt or the like. The total weight of the inner box 10 and the outer box 12 is, for example, about 350 g to 400 g. The outer box 12 containing the inner box 10 is used as a medical device disposal container in a hospital as it is or in a state in which the upper surface of the inner box 10 is opened by being inserted into, for example, a steel box. used. Then, the used injection needle and the like are introduced into the container through the introduction opening on the upper surface of the inner box 10.

When the medical device waste such as the injection needle is accumulated in the container and the inner box 10 is full of the waste, the closing lid 20 is formed together with the cardboard pieces forming the lid of the outer box 12. Configuration The belt fixing of the sheet pieces 18a to 18d (see FIG. 3) is released, the configuration sheet piece 18a is superimposed on the configuration sheet piece 18c, and both side ears of the insertion tongue piece 26a of the configuration sheet piece 18a are configured as the configuration sheet pieces. The upper surface (opening opening) is closed by inserting each of the constituent sheet pieces 18a and 18c into the respective insertion cuts 28a of the insertion sheet 18c to lock each other. Further, the constituent sheet piece 18d is superimposed on the constituent sheet pieces 18a and 18c, and the constituent sheet piece 18b is superimposed on the constituent sheet piece 18d. As shown in FIG. Both ears are inserted into the respective insertion cuts 28b of the component sheet piece 18d, and the component sheet pieces 22b and 22d are mutually locked. In this way, the charging opening is completely sealed by the double-walled closing lid 20.

When the charging opening of the inner box 10 is closed with the closing lid 20, the four cardboard pieces forming the lid of the outer box 12 are folded and the upper surface of the outer box 12 is closed as in a normal cardboard box. Then, as shown in FIG. 1, a gum tape 36 is attached to the joint of the cardboard pieces constituting the lid, and the upper surface of the outer box 12 is completely sealed. In this case, since the inner box 10 is formed of a sheet-shaped plastic material, there is no fear that the injection needle accommodated therein protrudes to the outer surface of the container. Waste such as injection needles are sealed in an inner box 10 made of a sheet-like plastic material, and the inner box 10 is further enclosed in an outer box 12 made of waterproof cardboard. The liquid is completely sealed, so there is no danger that liquid such as blood or chemicals remaining in the waste stored inside will leak to the outer surface of the container.
