EMBODIMENT OF THE INVENTION Hereinafter, the Example of the compression reduction and reduction apparatus of the infectious waste of this invention is demonstrated based on drawing.

Fig. 1 shows a conceptual diagram of an apparatus for compressing and reducing infectious waste of the present invention.

The infectious waste compaction apparatus 1 includes a container 2 containing an infectious waste W, a lid member 3 for sealing an opening of the container 2, and an infectious agent introduced into the container 2.

To make it work.

In this case, the container 2 containing the infectious waste W can be widely used as a container made of metal or synthetic resin, such as a general-purpose drum, which is conventionally used as a container for storing infectious waste.

The lid member 3 is not particularly limited in structure as long as it can substantially seal the opening of the container 2. However, the lid member 3 is made of metal capable of accommodating the raised compression plate 4 by forming an edge portion around the lid member 3. It can use suitably.

Moreover, the compression board 4 can use suitably what consists of metal board materials which have required intensity | strength (rigidity).

As the lifting mechanism 5, a general lifting device such as a hydraulic cylinder can be widely used.

In this case, the control mechanism (not shown) which the lifting mechanism 5 intermittently compresses and reduces the infectious waste W injected into the container 2 while repeating the descent and stopping of the compression board 4 (constantly). It is preferable to provide.

Therefore, when compressing and reducing the infectious waste W, the bag containing the infectious waste W is locally inflated and ruptured at once, and the impact can be reliably prevented from scattering.

Synthetic resin bags may be used as the bag for infectious waste W, but it is preferable to use general-purpose paper bags such as kraft paper.

Due to this, the infectious waste (W) is put in the paper bag and put into the container 2 so that the paper bag is sprayed into the container by the disinfectant spray mechanism 6 and wetted by the disinfectant solution, and the bag is locally inflated and ruptured. The impact can reliably prevent the infectious material from scattering.

In addition, when a bag made of synthetic resin is used, the bag is locally inflated and ruptured, and in order to prevent the infectious material from scattering due to the impact, the bag is placed at an appropriate location, for example, on the main surface or the lower surface of the compression plate 4, which is in contact with the bag. It is possible to install a blade (not shown) that breaks the air to form an air leakage hole.

The spray nozzle of the disinfecting liquid spraying mechanism 6 for spraying the disinfecting liquid into the container 2 is arranged in the lid member 3 in this embodiment.

The disinfectant solution is sprayed from the spray nozzle into the container 2 from the spray nozzle through the pump P from the tank T.

As the disinfectant solution sprayed from the disinfectant spray mechanism 6 into the container 2, a general disinfectant solution such as ethyl alcohol and an aqueous sodium hypochlorite solution corresponding to the infectious waste W can be widely used.

General purpose suction apparatuses, such as a ring blower, can be widely used for the suction mechanism 7 which sucks the gas in the container 2, and maintains the inside of the container 2 at negative pressure.

As a sterilization mechanism 8 for high-temperature sterilization of sucked gas, a general-purpose heating device (preferably capable of heating to about 800 ° C) such as a spot heater can be widely used.

For this reason, in the disinfecting liquid sprayed from the disinfecting liquid spraying mechanism 6 into the container 2, microorganisms, such as infant germs, which are hard to be sterilized can be reliably sterilized.

In the sterilization mechanism 8, a general purpose suction device including a cooling device such as a cooling fin disposed in a pipe through which the gas flows can be widely used for the cooling mechanism 9 for cooling the hot sterilized gas.

As the adsorption deodorization mechanism 10 which adsorbs and deodorizes the odor component contained in the gas cooled by the cooling mechanism 9, a general-purpose adsorption deodorant such as activated carbon and hydrous magnesium silicate (brand name "Sefio") can be used.

While the spraying of the disinfectant solution stops during this time, the suction amount of the gas is set at 360 L / min.

The lid member 3 is raised to a predetermined height position and stopped to stop the spraying of the disinfectant solution and the suction of the gas, thereby completing one step.

In addition, the stroke of (1)-(10) can be performed by automatic control by a control mechanism (not shown).
