Abstract

PURPOSE: To obviate the need for a place for storing housing containers of medical treatment waste and prevent the secondary contamination by waste gases of a waste incineration treatment by heating and melting a container consisting of a hot meltable synthetic resin and sterilizing the medical treatment waste with a melting device, recovering the melt from the melt outlet in the bottom to a receiving tray in the lower part, then solidifying the melt. CONSTITUTION: The housing container 11 in which the medical treatment waste is housed and which is hermetically sealed is housed in a melting kettle 6 of the melting device and a heater block 9 is lowered to hermetically seal the upper surface of the melting kettle 6. The housing container 11 in the melting kettle 6 is thereafter heated by energization to the heater block 9, by which the housing container 11 consisting of the hot meltable synthetic resin is melted and the medical treatment waste is sterilized. The molten resin is dropped together with the medical treatment waste from the melt outlet 7 in the bottom into the lower receiving tray 8. The molten resin in the receiving tray 8 is solidified and the medical treatment waste is confined into the solidified resin through a cooling stage for a specified period of time after the melting. The resin solidified by encapsulating the medical treatment waste may be handled as ordinary waste together with the receiving tray.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for treating medical waste discarded in various medical institutions and inspection institutions, and particularly to melting medical waste collected in a recovery container together with the container. The present invention relates to a treatment method for solidifying the.

[0002]

2. Description of the Related Art Medical waste such as syringes, blood transfusion equipment, etc., which are discarded at various medical institutions and inspection institutions, may be treated according to the medical waste treatment guidelines established by the Ministry of Health and Welfare due to problems such as contamination of the surroundings. Mandatory and its general processing process is as shown in FIG. That is, medical waste discarded in medical / inspection institutions is collected in a special synthetic resin recovery container (1), which is sealed and then temporarily stored (2). Is periodically collected, transported to the treatment facility (3), and incinerated at the treatment facility (4).

[0003]

By the way, in the above-mentioned prior art, since the medical waste collected in the medical institution or the like is temporarily stored until it is collected, the storage place is There is a drawback that it must be secured at each medical institution, and that when it is collected and transported, it must be transported by a special dedicated refrigerated vehicle in consideration of pollution to the surroundings. Moreover, even with a special cold storage car, there is still the danger of pollution to the surroundings due to an accident during its transportation. In addition, since the treatment method in the treatment facility also involves incineration of the collection container, there is a problem of secondary pollution due to the exhaust gas, and there is a problem that the exhaust gas treatment is difficult. In addition, the processing steps are complicated as a whole, which requires a lot of manpower and cost.

[0004]

SUMMARY OF THE INVENTION The present invention is based on the above-mentioned conventional restrictions on the treatment process of medical waste, it is necessary to secure a storage place for a recovery container, and there is a risk of contamination due to an accident during transportation.
In consideration of various problems due to complicated treatment processes such as exhaust gas pollution due to incineration treatment, a container made of heat-meltable synthetic resin that collects medical waste in a medical institution or an inspection institution is housed in a melting device and heated. The above problems are solved by melting and sterilizing the medical waste, collecting the melt from the melting outlet at the bottom into the lower pan, and solidifying the melt in the pan.

[0005]

According to the present invention having the above-mentioned structure, the collection container containing the medical waste to be discarded in the medical institution or the inspection institution is heated and melted as it is, the medical waste is sterilized, and the molten resin is solidified in the recovery tray. By confining the medical waste in the solidified resin, the risk of contamination is eliminated, and thereafter, the medical waste can be handled as normal waste.

[0006]

FIG. 2 shows an embodiment of the present invention. In the embodiment shown in FIG. 2, a melting outlet 7 is formed at the bottom of a melting pot 6 housed inside a casing 5 of the melting device,
A heat-resistant tray 8 is provided below it. Heat-resistant paper may be used as the heat-resistant material, and in this case, the paper-made tray 8 can be post-treated after the treatment. A heater block 9 is provided above the housing 5, and the block 9 is supported by a block elevating motor 10 so as to be able to ascend and descend, and when it descends, the upper surface of the melting pot 6 is sealed. Reference numeral 11 denotes a medical waste container made of a heat-meltable synthetic resin, which has a structure capable of being sealed. Then, it is the same as the conventional method that the above-mentioned container 11 is installed in each medical institution or inspection institution and medical waste is collected in the container 11.

In the present invention, the recovery container 11 for recovering medical waste in a medical institution or the like is treated by using the melting apparatus installed in each medical institution or the like. In the process, when the sealed container 11 for containing medical waste is housed in the melting pot 6 of the melting device, the block elevating motor 10 lowers the heater block 9 to seal the upper face of the melting pot 6. . Then, when the container 11 in the melting pot 6 is heated by energizing the heater block 9, the container 11 made of a heat-meltable synthetic resin is melted and the medical waste is sterilized.
The molten resin is dropped together with medical waste from the melting outlet 7 at the bottom into the pan 8 below.

When the molten resin is dropped and contained in the tray 8, the molten outlet 7 may be always open so that the molten resin may be sequentially dropped, or a closed body may be provided at the molten outlet 7. Alternatively, after closing a certain amount or all of them are melted, the closing body may be opened and dropped on the pan 8. Further, the heating temperature and the heating time depend on the material of the container 11, but from the viewpoint of sterilization of medical waste, it is preferably 200 ° C. or higher and about 2 hours. After the melting, the molten resin in the tray 8 is solidified through a cooling process for a certain period of time, and the medical waste is contained in the solidified resin. The resin thus encapsulated and solidified with the medical waste that has been sufficiently sterilized is then treated as a normal waste together with the tray 8 to facilitate the treatment.

[0009]

As described above, according to the present invention, in the treatment of medical waste, the accommodating container made of the heat-fusible resin material containing the medical waste is sterilized and melted by the melting device. However, since it solidifies and encloses the medical waste in the solidified resin, the treatment can be carried out in each medical institution or inspection institution only by installing the melting device, and It has an excellent effect that it does not require a vast storage space for storage, it does not require complicated work such as transportation by a special transportation vehicle, and there is no risk of contamination due to an accident during transportation work. It is a thing.

Further, since the medical waste is sterilized and contained in the coagulation resin, the subsequent handling can be handled in the same manner as ordinary waste, and since it is melted and coagulated, the whole is treated. The volume of is also much smaller than that of the storage container, and can be handled efficiently during transportation. Moreover, since it is not a treatment by incineration, there is no concern about secondary pollution due to exhaust gas.
