Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for treating plastic medical waste material, and more particularly, to dispose of plastic medical waste material at home or a small clinic in the same manner as general plastic waste. The present invention relates to a medical waste material processing apparatus and a processing method suitable for the above.

[0002]

2. Description of the Related Art In order to ensure the safety of patients and medical staff,
Plastic medical disposable equipment is widely used. However, when disposing of medical disposable equipment, strict management is required from the viewpoint of public health and prevention of pollution while ensuring safety. In addition to the disposal of medical disposable equipment, there is a strong demand for reducing the volume of waste and reducing the amount of exhaust gas generated during disposal when disposing of general waste.

Conventionally, plastic medical waste materials are disposed of in the following manner: (a) incineration, (b) crushing and sterilization, (c) dumping and landfilling, and (d) melting and volume reduction. Various methods such as processing have been proposed.

That is, (a) incineration is a method of incinerating plastic medical waste using an incinerator.
In addition, (b) crushing / sterilizing treatment is to crush plastic medical waste material using a mechanical crushing device and to perform sterilization treatment. In this way, plastic medical waste can be reduced in volume and sterilized.

(C) Discarding and landfilling is a method of burying medical waste materials directly in the ground. (D) Melting
The volume reduction treatment method is a method in which plastic medical waste material is melted by a melting device to reduce the volume and sterilize (for example, JP-A-3-1930056, JP-A-4-499).
No. 71, JP-A-4-284206, JP-A-4-284
-327848, JP-A-8-71140, etc.).

[0006]

However, the above-mentioned various processing methods have the following problems. (B) In the incineration treatment, there is a problem that the incinerator is damaged by the amount of heat generated by the burning of the plastic, and the generated exhaust gas causes environmental pollution. Therefore, it was necessary to use an incinerator capable of withstanding high temperatures, and to further provide an apparatus for treating exhaust gas. Also, as raw materials for plastic medical waste materials,
Although a soft vinyl chloride resin is widely used, there is a problem that harmful substances such as dioxin may be generated during incineration.

(B) In the case of pulverization and sterilization, there is a problem that a large and complicated processing device is required, and the cost is extremely high due to the use of a bactericide or the like. Further, there is a problem that an unpleasant odor tends to be generated during the treatment.

(C) In the dumping and landfill treatment, sterilization and volume reduction of medical waste materials cannot be achieved, so that they cannot be used at present. (D) The melting and volume reduction treatment is an excellent treatment method that can solve the problems of the incineration treatment, the pulverization / sterilization treatment, and the dumping / landfill treatment described above. However, in the conventional melting and volume reduction treatment method, a large-scale deodorizing device had to be installed in order to prevent an unpleasant odor generated during treatment from a chemical solution, a body fluid or a waste solution attached to plastic medical waste material. . Therefore, the apparatus itself for performing the melting and volume reduction processing is large-scale and expensive, and also requires a deodorizing apparatus. Did not.

[0009] In the processing apparatus disclosed in Japanese Patent Application Laid-Open Nos. Hei 3-193056 and Hei 8-71140, after putting used plastic medical waste material into a plastic bag or box, Melting / volume reduction processing is being performed. However, in this type of plastic bag or box, no consideration is given to gas barrier properties for preventing off-flavors. In addition, the plastic bag or box may be damaged during processing due to local heating, and an unpleasant odor may leak.

Therefore, even in the processing apparatuses disclosed in Japanese Patent Application Laid-Open Nos. Hei 3-193056 and Hei 8-71140, it is necessary to separately provide a deodorizing device or the like in order to prevent an unusual odor.

Further, the above-mentioned conventional methods and apparatuses for treating plastic medical waste materials are merely for treating a large amount of medical waste materials. On the other hand, in recent years, patients are increasingly using plastic disposable medical equipment at home, such as peritoneal dialysis. In such a case, the used medical disposable equipment must be disposed of and disposed of at the patient's home. Similarly, small clinics often have to dispose of disposable medical plastic equipment.

However, plastic medical waste cannot be disposed of at home or in a small clinic like other general plastic waste. Therefore, it is necessary to entrust disposal to a medical waste material processing company, and the cost for disposal is extremely high. Therefore, there is a strong demand for a method that can safely and inexpensively dispose of used plastic medical waste materials at home and in small clinics.

It is an object of the present invention to enable plastic medical waste to be reduced in volume and sterilized, so that it can be disposed of in the same manner as ordinary plastic waste, and to be small and inexpensive. It is an object of the present invention to provide a waste material treatment device and a medical waste material treatment method.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be clarified by describing non-limiting embodiments of the present invention with reference to the drawings.

FIG. 2 is a perspective view showing the appearance of a medical waste material treatment apparatus according to one embodiment of the present invention. The medical waste material treatment apparatus 1 has a rectangular parallelepiped case body 2. Although not particularly limited, the case body 2 is made of a porous metal material having a large number of through holes 2a in this embodiment. As described above, by forming the case main body 2 from a porous metal material, the heat radiation effect can be enhanced, which is preferable. Of course, case body 2 may be formed of a metal mesh, or may be formed of a metal plate having no through-hole.

The case body 2 is provided with a drawer 3 at an intermediate height position. The drawer 3 is configured to be able to be pulled out from the case main body 2. FIG. 3 shows a state where the drawer 3 is pulled out from the case main body 2.

In this embodiment, the drawer 3 is made of stainless steel, but may be made of a metal material other than stainless steel, or may be made of a heat-resistant resin. However, it is preferable that the drawer 3 be made of a metal having excellent thermal conductivity in order to heat a package body described later.

As shown in FIG. 4, the drawer 3 is provided for accommodating a package described later, and has a rectangular planar shape in this embodiment. That is, the drawer 3 is
a, a front plate 3b, a rear plate 3c, and side plates 3d and 3e formed to extend upward from the outer peripheral edge of the bottom plate 3a. In addition, a handle 3f is attached to the front surface of the front plate 3b.

A drop lid 4 is provided so as to be stored in the drawer 3. Drop lid 4 drawer 3
When the package is stored in the inside, the package is pressed down in advance to reduce the volume. The drop lid 4 is made of metal so as to have such a function, and preferably has a certain weight. However, the drop lid 4 may be made of a synthetic resin other than a metal as long as the above-mentioned action can be achieved. The outer shape of the drop lid 4 is such that it can enter the drawer 3.
It is smaller than the upper opening of the drawer 3.

Returning to FIG. 2, a rod 5 having an external thread 5a formed on the outer peripheral surface so as to pass through the upper surface 2b of the case body 2 is provided.
Is attached. At the upper end of the rod 5, an operation handle 6 is fixed to the rod 5 so as to be able to rotate together with the rod 5. A handle 7 is attached near the end of the operation handle 6 opposite to the portion where the rod 5 is fixed.

Further, as shown in a vertical sectional view in FIG. 5, a through hole 2c is formed in the upper surface 2b of the case body 2.
A bearing 8 having a female screw portion formed on the inner peripheral surface thereof to be fitted with the male screw 5a of the rod 5 is fixed to the through hole 2c.

Accordingly, the rod 5 is moved upward or downward by holding the handle 7 of the operating handle 6 by hand and rotating the operating handle 6 around the axial center of the rod 5.

A support plate 9 is connected to a lower end of the rod 5. That is, the through holes 9a are formed in the support plate 9.
Is provided, and a connecting portion having a relatively small diameter at the lower end of the rod 5 is inserted into the through hole 9a. Through hole 9a
Is provided with a bearing 10 and a through hole 9
In order to prevent the rod 5 from falling out of the through hole 9a, the tip of the connecting portion of the rod 5 is provided on the lower surface of the through hole 9a.
It is crushed to have a diameter larger than a. Therefore, the rod 5 is provided rotatably with respect to the support plate 9, but is connected to the support plate 9 so that the support plate 9 does not drop downward.

The support plate 9 can be made of an appropriate material such as a metal or a synthetic resin. However, in order to support a press plate as a press member described later, it is preferable that the support plate 9 be made of a metal plate having excellent rigidity. desirable.

In the support plate 9, a plurality of through holes are provided around a portion where the rod 5 is connected, and the connecting rods 12a and 12b are inserted into the through holes. The upper ends of the connecting rods 12a, 12b extend above the support plate 9, and the lower ends are fixed to the press plate 13.

E-rings 11a, 11b are fixed to the upper portions of the support plates of the connecting rods 12a, 12b, whereby the connecting rods 12a, 12b are lower than the second state shown in FIG. 12b is configured not to fall.

The lower surface of the support plate 9 and the press plate 1
The compression springs 14a, 14b are extrapolated to the connecting rods 12a, 12b between the upper surfaces of the compression rods 3 and 3. Therefore, when the support plate 9 is brought close to the press plate 13, the elasticity of the compression springs 14a and 14b acts to move the press plate 13 away from the support plate 9.

The press plate 13 has a heat insulating plate 13a and a metal plate 13b arranged on the lower surface side of the heat insulating plate 13a.
A through hole (not shown) is formed in the heat insulating plate 13a.
The connecting rods 12a and 12b are inserted into the through holes. The lower ends of the connecting rods 12a and 12b are
3b. The reason why the metal plate 13b is used is that it is possible to press a package body described later in a sufficiently heated state. Further, the heat insulating plate 13a is a metal plate 1
This is to prevent the heat of 3b from being transmitted to the connecting rods 12a and 12b. The heat insulating plate 13a is made of a material having an appropriate heat insulating property, such as a borate-based or phosphate-based ceramic plate-like member or an inorganic plate-like member reinforced with glass fiber. A plate-like member can be used.

Although the heat insulating plate 13a is overlaid on the metal plate 13b, they may be integrated by bonding or the like. The press plate 13 is suspended. Meanwhile, the press plate 13 is located above the drawer 3 arranged below at the position (first position) shown in FIG.

By rotating the operating handle 6 to move the rod 5 downward, the press plate 13 is also lowered. In this case, in the lowered state (second state), the press plate 13 is located in the drawer 3.

On the other hand, the press plate 13 is configured so as to be able to enter the inside of the drawer 3, and the rear surface thereof is arranged to be in contact with the inner surface of the rear plate 3 c of the drawer 3 or to be arranged with a slight gap therebetween. Have been. When the press plate 13 enters the drawer 3, even if the drawer 3 is to be pulled forward as shown in FIG. 1, the inner surface of the rear plate 3 c of the drawer 3 contacts the rear surface of the press plate 13 and the drawer 3 is pulled out. Is considered impossible. Therefore, it is not possible to take out a later-described package stored in the drawer 3 until the end of the heating press.

As shown in FIG. 5, a shelf 15 for supporting the drawer 3 is provided below the drawer 3. The shelf 15 is made of a metal plate and fixed to the case body 2. However, the shelf 15 may be made of a material other than metal as long as the shelf 15 has excellent thermal conductivity. Below the shelf 15, a heater 16 schematically shown is mounted so as to be thermally coupled to the shelf 15. Therefore, the heater 16
Is transmitted to the drawer 3 via the shelf 15 and eventually to the package inside the drawer 3. As shown in FIG. 2, the start switch 1a for turning on the heater 16 is provided on the upper surface 2 of the case body 2.
b. On the upper surface 2b, a lamp 1b indicating that heating is being performed, a lamp 1c indicating that cooling is being performed, and a reset switch 1d are provided. In FIG. 5, since a later-described package is not shown, the drop lid 4 is placed on the bottom plate 3 a of the drawer 3.

Next, a method for treating medical waste material using the treatment apparatus of this embodiment will be described. First, as shown in FIG.
The medical waste material 17 is placed on the synthetic resin sheet 18. The target medical waste material is not particularly limited, and examples thereof include various disposable plastic medical devices such as a peritoneal dialysis solution bag.

Further, the synthetic resin sheet 18 is used for preventing the medical waste material 17 from touching the hand and for trapping an unpleasant odor during the heat treatment. Therefore, as long as it has a gas barrier property sufficient to confine the off-flavor, a material made of an appropriate synthetic resin can be used.

However, preferably, not only is the gas barrier property excellent, but also the bottom plate 3a of the drawer 3 and the press plate 1
A synthetic resin material which can be easily peeled off from the third metal plate 13b after hot pressing is used. Examples of such a preferable synthetic resin material include a polyethylene terephthalate resin and a polybutylene terephthalate resin.

The medical waste material 1 is placed on the synthetic resin sheet 18.
7, the medical waste material 17 is wrapped with a synthetic resin sheet 18 and a package 19 shown in a schematic sectional view in FIG.
Get. In FIG. 7, the cross section of the package 19 is schematically shown. In this state, the medical waste material 17 is not compressed, and therefore has a relatively large thickness and an extra space inside. I have.

The material of the package 19 is not limited to the synthetic resin sheet 18, but a bag made of synthetic resin may be used. When using bags, medical waste materials 17
It is preferable to use a bag that is sufficiently large as compared with the above. After storing the medical waste material 17 in the bag, it is desirable to wrap the medical waste material 17 using an excess portion of the bag.

Further, in order to prevent the leakage of the unusual odor, it is preferable that the medical waste material 17 is wrapped at least twice by the synthetic resin sheet 18. However, the wrapping method is not particularly limited, and any method can be used as long as the medical waste material 17 can be completely wrapped.

Next, as shown in FIG. 8, the package 19 is housed in the drawer 3 of the processing apparatus 1 and the drop lid 4 is placed. The drop lid 4 has a sufficient weight to press the package 19 as described above. Therefore, by placing the drop lid 4 on the package 19, the package 19 is compressed in advance, and the upper surface of the drop lid 4 is positioned in the drawer 3. As described above, since the drop lid 4 is used to compress the package 19 in advance, when the drop lid 4 is placed on the package 19 as described above, the upper surface 4a of the drop lid 4 is pulled out. It is desirable to use a material having a weight such that it is located within the area 3.

Next, the drawer 3 containing the package 19 and the drop lid 4 is inserted into the case body 2. At this time, the press plate 13 is set at the first position in the case body 2. Next, the operating handle 6 is rotated to lower the rod 5, and thus the press plate 13, and lower the press plate 13 to the second position. Thereafter, when the start switch 1a is pressed, the lamp 1b is turned on, the heater 16 is turned on, and the drawer 3 and the package 19 in the drawer 3 are heated. At the same time, the metal plate 13b of the press plate 13 comes into contact with the upper surface of the drop lid 4, and the package 19 is pressed.

Accordingly, the package 19 is pressed under heating. The degree of this heating depends on the resin material constituting the medical waste material, but when the medical waste material is made of a soft vinyl chloride resin, a temperature at which the soft vinyl chloride resin can be softened, for example, 170 ° C. or higher It is said. In this way, the medical waste material 17 in the package 19 is softened under heating, and the weight of the drop lid 4 and the compression spring 14 are reduced.
The elongation of a and 14b crushes the package 19, thereby reducing the volume of the package 19 and sterilizing by the heating.

Further, in the heating press, since the medical waste material does not burn, no combustion gas is generated. In addition, the temperature in the drawer 3 during heating is as high as about 160 to 220 ° C. Therefore, not only is the sterilization treatment performed, but there is a possibility that an unusual odor may be generated from the dirt, gas, or plastic itself attached to the medical waste material 17. However, since the medical waste material 17 is wrapped in the synthetic resin sheet 18, it is unlikely that an unusual odor leaks to the outside.

In particular, when a polyethylene terephthalate-based resin or polybutylene terephthalate-based resin is used as the synthetic resin sheet 18, since it has excellent gas barrier properties, it is possible to more effectively prevent leakage of off-flavors, malodors or pungent odors. be able to.

The heating press time varies depending on the type of resin constituting the target medical waste material 17, the shape and size of the medical waste material 17, the heating temperature, and the like.
Usually, it may be about 10 to 60 minutes.

During the hot pressing, since the press plate 13 is located in the second state, that is, in the drawer 3,
As shown in FIG. 1, the drawer 3 cannot be pulled out even if it is to be pulled forward, that is, in the direction of arrow A.
Accordingly, it is possible to reliably prevent an accident such that the drawer 3 accidentally slips out during the hot press and the operator gets burned.

As a result of the heating press, the package 19 is reduced in volume and sterilized in the drawer 3 to form a flat block 19A as schematically shown in FIG. After heating for a predetermined time, the lamp 1c is turned on, the heater 16 is turned off, the heating is stopped, and heat is naturally radiated. The lighting of the lamp 1c indicates that the drawer 3 and the package 19 in the drawer 3 are in a high temperature state. When the cooling is completed after a predetermined time, the lamp 1c is turned off, the power of the apparatus is turned off, and the process ends. Thereafter, the operation handle 6 is rotated counterclockwise to raise the press plate 13 and return to the first state. As a result, the drawer 3 can be taken out of the case main body 2, so that the drawer 3 is pulled out and the block 19 after the internal processing is processed.
A may be taken out and discarded. In this case, the block body 19A is very thin and small, and is further sterilized, so that it can be discarded in the same manner as ordinary plastic waste.

Next, specific experimental examples will be described. A used peritoneal dialysis solution bag was used as the medical waste material 17 to perform disposal processing. The peritoneal dialysate bag is a dialysate bag containing the dialysate (dimensions: 17 cm x 35 c
m) and a drainage bag (dimensions of about 20 cm x 30 cm) containing used dialysate are connected by tubes (outer diameter 7 mm, inner diameter 5 mm and length about 2 m). ing. A used peritoneal dialysate bag, which was discarded and emptied from the used dialysate contained in the drainage bag, was placed in a 25 μm-thick 40 × 40 cm polyethylene terephthalate sheet (manufactured by Toray Industries, trade name: Luminar S type # 2)
5) Double packaging was performed using two sheets.

The package obtained in this way is 15 cm long.
× 20 cm wide × 5 cm high drawer 3, dropping lid 4 stainless steel 1 cm thick and about 1 kg in weight from above
Was placed.

After that, the drawer 3 was set on the case main body 2 and heated and pressed. At the time of heating press, the operation handle 6 described above is rotated, the packing body 19 is compressed by the press plate 13 and the cover 19 via the cover 4, and the built-in 500 W heater is used at a temperature of 170.degree.
Heated for 0 minutes. Then, after naturally cooling for 120 minutes, the volume reduced and sterilized block body 19A from the processing apparatus 1 is formed.
Was taken out.

In this case, the block body 19A is much smaller than the peritoneal dialysate bag of the treatment membrane,
The size was 5 cm × 20 cm × 2 cm in height. Further, since the block body 19A is heated under the above-described conditions, it is sterilized, and thus can be easily disposed of like ordinary plastic waste.

[0055]

In the apparatus for treating medical waste according to the first aspect of the present invention, a package in which the plastic medical waste is wrapped in a synthetic resin sheet or a bag is stored in a drawer and provided in a case body. Since the package in the drawer is heated by the heater and the package is pressed by the pressing member, volume reduction and sterilization of the package are simultaneously performed. Therefore, medical waste materials that have been reduced in volume and sterilized
It can be handled in the same manner as ordinary plastic waste and can be easily disposed of like the plastic waste.

In addition, since the processing apparatus has a relatively simple configuration including a drawer, a press member, and a press member driving mechanism, automation and miniaturization are easy. Therefore, a large space is not required at the installation location, and the operation can be easily performed. Therefore, it is possible to provide a processing device suitable for use in a general home or a small clinic.

Furthermore, the package containing the above-mentioned medical waste material is processed by pressing under heating, and no toxic gas is generated by combustion because the incineration process is not performed. In addition, there is no need for a facility for treating toxic gas generated by combustion.

Further, in the treatment, the medical waste material is wrapped in advance with a synthetic resin sheet or bag to constitute a package, so that the leakage of an odor generated during hot pressing is suppressed by the synthetic resin sheet or bag.

In addition, since the drawer cannot be pulled out of the case body during the heating press, there is no possibility of an accident such as a burn. Therefore, by using the medical waste material treatment apparatus according to the first aspect of the present invention, it is possible to easily, safely, and inexpensively dispose of medical waste material at home or in a small clinic.

According to the second aspect of the present invention, since the dropping lid for pressing the package housed in the drawer prior to pressing is further provided, the drawer containing the package is set in the case body. Not only can be performed easily, but also the package can be pressed more reliably during the hot pressing.

In the method for treating medical waste according to the present invention, a package is obtained by wrapping a plastic medical waste in a synthetic resin sheet or a bag, and then pressing the package under heating. Volume and sterilize it to make it a disposable block. Therefore, similarly to the first aspect, the medical waste material can be disposed of in the same manner as ordinary plastic waste. In addition, since medical waste materials are packed in advance in a synthetic resin sheet or bag, an unpleasant odor is unlikely to be generated during hot pressing. In addition, since no combustion treatment is performed, no toxic gas is generated by combustion.

In the method for treating medical waste material according to the fourth aspect of the present invention, it is only necessary to press under heating after obtaining the package as described above. It can be easily implemented by a relatively simple device such as the processing device, and the disposal cost of medical waste materials can be effectively reduced.

According to the third and fifth aspects of the present invention,
Since the synthetic resin sheet or bag is made of polyethylene terephthalate-based resin or polybutylene terephthalate-based resin, it has excellent gas barrier properties, and thus can reliably prevent leakage of off-flavors generated from dirt and liquid during hot pressing. In addition, the block processed after the hot pressing can be easily removed from the processing device portion made of metal or the like.
