Description

Detailed Description of the Invention

[Field of Industrial Application] The present invention relates to microorganisms such as bacteria and viruses existing in water and sewage water, blood, plasma components and other solutions, or ammonia, bilirubin,
The present invention relates to a technique necessary for sterilizing and inactivating or adsorbing poisonous substances.

[0002] Conventionally, as a method for sterilizing and inactivating viruses, drugs and vaccines have been used to sterilize and inactivate viruses, but against viruses such as HIV virus and hepatitis virus and carcinogenic virus. However, at present, there is no established effective treatment method.

[Problems to be solved by the invention] Sterilization and inactivation or adsorption of microorganisms such as bacteria and viruses or ammonia, bilirubin, toxic substances and the like present in water and sewage water, blood, plasma components, seawater and other solutions. The purpose is to do.

[Means for Solving the Problems] FIG. 1 is a diagram for explaining the principle of the present invention. FIG. 1 is a longitudinal sectional view, in which 1 is a filtering instrument made of an insulating material such as glass, and 2 is a filter. Electrodes, 3 are terminals, 4 are crosspieces, 5 is a filtering material made of breathable conductor,
7 is a hole or the like.

[Operation] The HIV virus in the free state existing in blood or the voltage in the range that does not destroy important cells in blood such as red blood cells, white blood cells and plasma plates It utilizes the phenomenon of being able to inactivate or suppress the HIV virus which is non-covalently bound on the surface of cells.

[0006] As a means for uniformly flowing an electric current in a solution, spherical particles or granules or porous or honeycomb shapes made of conductors such as gold, platinum, carbon, activated carbon, titanium, palladium or nickel are used. When a solution of an electrolyte such as blood or seawater is passed through the inside of the filtering instrument 1 which uses an object or a carbon fiber as the filtering material 5, a large amount even at low voltage without raising the temperature of the solution. Current of
Since it can be evenly flowed in a solution such as blood or seawater, it is possible to uniformly sterilize and inactivate or adsorb microorganisms such as bacteria and viruses or ammonia, bilirubin, poisons and the like present in the solution.

When an electric current is passed through an electrolyte solution such as blood or a plasma component obtained by separating blood or seawater, an electric current is passed through the electrolyte solution without using the filter medium 5 made of a gas permeable conductor. And, an extremely thin passage for the flow of an electric current is formed in the solution, and the electric current has a property of flowing only in a desired place in the solution. Therefore, unless the filter medium 5 made of a gas permeable conductor is used, There is a problem that an electric current cannot be evenly flowed in the electrolyte solution.

[0008] Currently, as a means for adsorbing and removing ammonia, bilirubin, poisons and the like in blood, a product with a trade name of Hemofilter is used for treatment. This hemofilter is a spherical type of activated carbon of several millimeters. Shaped,
The surface of the particles made of activated carbon is coated with a biocompatible heparin coat or the like that is compatible with the living body, and the particles made of activated carbon are used as the filter medium 5 to remove ammonia, bilirubin and poisons in blood. It is adsorbed and removed by the filter medium 5 made of activated carbon.

Using the present invention, the terminals 3 are provided at both ends of the filter device 1 filled with the spherical filter material 5 made of activated carbon called hemofilter as described above. As shown in FIGS. 1 and 2, an electrode 2 or an electrode 6 is provided so as to come into contact with the spherical filtration material 5 made of activated carbon filled in the filtering instrument 1, and the activated carbon is activated. By passing an electric current within the range that does not affect the blood and the living body through the spherical filter medium 5 made in (2), the adsorption capacity of activated carbon is dramatically improved.

The surface of the spherical or porous or honeycomb-shaped filter material 5 used as the filter material 5 made of a gas permeable conductor is biocompatible, such as a heparin coat, which is compatible with a living body. Surface treatment using resin or resin of insulator,
By using the filter medium 5 made of a conductor, which has a reduced conductive property as a conductor, the charge capacity of the filter medium 5 made of a conductor is increased. There is a characteristic to do.

When a large amount of electric current is applied to seawater to kill and inactivate microorganisms such as bacteria and viruses in seawater and fish and shellfish are cultivated and cultivated in seawater, no fish diseases occur. In this condition, fish disease can be suppressed.

[Embodiment] An embodiment of the present invention will be described below with reference to FIG. FIG. 2 is a structural schematic explanatory view showing an electric filtering means of an embodiment of the present invention, and FIG. 2 is a longitudinal sectional view showing 1
Is a filtering device made of an insulating material such as glass, 2 is an electrode, 3 is a terminal, and 5 is a filtering material made of a breathable conductor,
6 is a breathable electrode, and 7 is a hole or the like.

As shown in FIG. 2, the inside of the filtering device 1 is filled with a filter material 5 made of a conductor and made of a conductor and having a spherical shape with a diameter of about several millimeters. Then, by contacting the air-permeable electrodes 6 made of a conductor provided above and below, a negative electrode or a positive electrode current is caused to flow through the spherical filter material 5 made of a conductor to give a breathable conductor. Filter material made of 5
In the same manner as in the artificial dialysis procedure, the blood instrument or the plasma component or the serum component in which the blood of the human body is drawn out is introduced into the inside of the filter instrument 1 in which a current of the negative electrode or the positive electrode is passed. Of the blood or plasma component or serum component that is circulated extracorporeally in the inside of the filtration device 1 is applied with voltage and current in the inside of the filtration device 1 so that a free state existing in the blood or plasma component or serum component is present. The HIV virus and the HIV virus non-covalently bound to the cell surface are electrically repelled so that they do not pass through the inside of the filter medium 5 made of a breathable conductor or are electrically adsorbed, or sterilized and It shows the inactivated state.

[Effects of the Invention] Blood or plasma components can be obtained by passing an electric current through a filter material made of a gas permeable electric conductor, which has a spherical shape or porous or honeycomb shape made of an electric conductor. Since a large amount of current can be evenly flowed in a solution of an electrolyte such as a low voltage even in a low voltage, HI existing in blood or a plasma component or serum component separated from blood
Since the virus such as V virus can be uniformly inactivated, the HIV virus cannot be completely eradicated from the human body, but the HIV virus in the blood is inactivated and the HIV virus in the blood is inactivated. There is an effect as a therapeutic means that the onset of AIDS can be delayed by reducing the number of viruses.
