Abstract

A filtration and collection device capable of improving the collection rate of filtration targets. The filtration and collection device may include a holder having an inlet port for pouring a liquid, a discharge port for discharging the liquid, a flow path through which the inlet port and the discharge port communicate, and a groove portion formed on an outer periphery of the holder, a filter disposed in the flow path of the holder and having a plurality of through-holes, and one or a plurality of grip sections having an insertion portion that is inserted into the groove portion, in which a gap is formed between the groove portion and the insertion portion.

First claim

The invention claimed is:

1 . A filtration device comprising:
a holder including:
an inlet port configured to receive a liquid,
a discharge port configured to discharge the liquid,
a flow path through which the inlet port and the discharge port communicate, and
a groove portion formed on an outer periphery of the holder;
a filter disposed in the flow path of the holder and including a plurality of through-holes; and a grip section including an insertion portion that is inserted into the groove portion, wherein a gap is formed between the groove portion and the insertion portion; wherein a thickness of the groove portion is greater than a thickness of an end of the insertion portion, and a distance between an edge of the insertion portion and a bottom of the groove portion is greater than zero, and wherein the grip section is configured to independently and individually rotate about the holder and is formed in a flat plate shape and is stacked in a thickness direction.

2 . The filtration device according to claim 1 , wherein the holder further includes:
a first holder including a tubular shape and the groove portion, and a second holder configured to be fitted into the first holder, and wherein the filter is held by the first holder and the second holder.

3 . The filtration device according to claim 1 , wherein the insertion portion is formed with a plurality of notch portions.

4 . The filtration device according to claim 3 , wherein the plurality of notch portions are provided at equal distances.

5 . The filtration device according to claim 1 , wherein the grip section and has a first surface, and one or a plurality of convex portions are formed on the first surface.

6 . The filtration device according to claim 1 , wherein the filter includes at least one of a metal or a metal oxide.

7 . The filtration device according to claim 1 , wherein the discharge port is in communication with a centrifuge tube.

8 . The filtration device according to claim 1 , wherein the plurality of through-holes are a rectangle shape in which a length of one side in a radial direction of the filter is longer than a length of one side in a thickness direction of the filter.

9 . The filtration device according to claim 1 , wherein a width of the groove portion is 1.1 times or more but less than 2 times a thickness of the grip section.

10 . The filtration device according to claim 1 , wherein the groove portion formed on the outer periphery of the holder is annular in shape.

11 . The filtration device according to claim 1 , wherein less than an entire circumference of the grip section comes into contact with the holder.

12 . A filtration device comprising:
a tube including an inlet port and an outlet port; a flow path through which the inlet port and the outlet port communicate; a filter disposed in the flow path of the tube; an indentation formed on an outer periphery of the tube; a plate including an insertion portion that is configured to engage with the indentation of the tube, and a void formed between the indentation and the insertion portion; wherein a thickness of the indentation is greater than a thickness of an end of the insertion portion, and a distance between an edge of the insertion portion and a bottom of the indentation is greater than zero, and wherein the plate is configured to independently and individually rotate about the tube and is formed in a flat plate shape and is stacked in a thickness direction.

13 . The filtration device according to claim 12 , wherein the tube further includes:
a first tube including a tubular shape and the indentation, and a second tube configured to be fitted into the first tube in a vertical direction, and wherein the filter is held by the first tube and the second tube.

14 . The filtration device according to claim 12 , wherein the insertion portion is formed with a plurality of notch portions.

15 . The filtration device according to claim 14 , wherein the plurality of notch portions are provided at equal distances.

16 . The filtration device according to claim 12 , wherein the plate is formed in a flat shape and has a first surface, and one or a plurality of convex portions are formed on the first surface.

17 . The filtration device according to claim 12 , wherein the filter includes at least one of a metal or a metal oxide.

18 . The filtration device according to claim 12 , wherein the outlet port is in communication with a centrifuge tube.

19 . The filtration device according to claim 12 , wherein the filter includes a plurality of through-holes in a rectangle shape in which a length of one side in a radial direction of the filter is longer than a length of one side in a thickness direction of the filter.

20 . The filtration device according to claim 12 , wherein the plate has a first side and a second side, and further includes an opening perpendicular to the first side and second side.
