Abstract

The invention relates to a material for capturing microbes or the like, a device for capturing microbes or the like, a method of capturing microbes or the like, and a method of producing a material for capturing microbes or the like, and has an object of using a pulverizable resin whereby a minor amount of microbes or the like contained in a large amount of a liquid, or microbes or the like contained in a small amount of a liquid can be captured efficiently, quickly, labor-savingly, and reliably. Disclosed is: a material for capturing microbes or the like, which comprises irregular-shaped powdery grains made of a pulverizable adsorbent resin and distributed in a predetermined grain size range, and which can adsorb or bond to a target such as a microbe contained in a liquid; a device for capturing microbes or the like; and a method of capturing microbes or the like.

1 . A device for capturing microbes including; irregular-shaped powdery grains made of a pulverizable adsorbent resin and distributed in a grain size range from 1 μm to 100 μm, an irregular-shaped powdery-grains holding section that allows passage of a liquid and holds the irregular-shaped powdery grains so as to be able to come in contact with the passing liquid, and a container that receives said liquid having passed through said irregular-shaped powdery-grains holding section,
 and said irregular-shaped powdery-grains holding section includes two filters having a pore diameter smaller than said grain size range of said irregular-shaped powdery grains, 
 and said irregular-shaped powdery grains are provided so as to be placed between the two filters, and the freedom of said powdery grains inside said irregular-shaped powdery-grains holding section is determined by changing the distance between said two filters based on the density of said target including any one of microbes selected from bacteria, fungus, protozoa, cells, and biomedical tissue. 
 
     
     
         2 . A device for capturing microbes according to  claim 1 , further including a flow channel in which one or a plurality of ports for performing liquid suction or discharge are provided and a liquid can move therein, and a pressure adjusting mechanism for adjusting pressure in said flow channel, and said irregular-shaped powdery-grains holding section occupies a certain area of said flow channel, and said container is provided outside said flow channel so that said one or said plurality of ports can be inserted therein. 
     
     
         3 . A device for capturing microbes according to  claim 1 , wherein said container includes a stirring container provided so as to be rotatable about an axis of rotation penetrating the container, and provided with a stirring wall protruding from an inner wall of the container toward the axis of rotation. 
     
     
         4 . A device for capturing microbes according to  claim 2 , wherein said plurality of ports of said flow channel are a suction port for sucking a liquid and a discharge port for discharging a liquid, said pressure adjusting mechanism is for sucking a liquid from said suction port and causing the liquid to flow out from said discharge port, and said irregular-shaped powdery-grains holding section is provided between said suction port and said discharge port of the flow channel. 
     
     
         5 . A device for capturing microbes according to  claim 1 , wherein said irregular-shaped powdery-grains holding section is provided detachably with respect to said flow channel. 
     
     
         6 . A device for capturing microbes according to  claim 1 , wherein said flow channel is formed of an extendable elastic body, and has a peristaltic pump as a pressure adjusting mechanism. 
     
     
         7 . A device for capturing microbes according to  claim 3 , wherein said plurality of ports of said flow channel are a suction port for sucking a liquid and a discharge port for discharging a liquid, said pressure adjusting mechanism is for sucking a liquid from said suction port and causing the liquid to flow out from said discharge port, and said irregular-shaped powdery-grains holding section is provided between said suction port and said discharge port of the flow channel.
