Abstract

A microorganism sampling device includes: a head part that has a water supply channel to which a water supply pipe for supplying sample water can be connected; a housing part to an upper part of which the head part can be detachably attached; a frame-structured tube; a tubular filter that is arranged within the tubular body; a cup that communicates with the tubular filter and is attached to one end of the tube body; and a cap that has a channel communicating with the tubular filter and is attached to the other end of the tube body. The microorganism sampling device further includes a filter part housed in the housing part, in which a bottom part of the cup is supported by a bottom part of the housing part. The head part is attached to an upper part of the housing part.

First claim

1 . A microorganism sampling device for sampling microorganisms existing in water, comprising:
a lid part having a water supply channel allowing a water supply pipe to be connected thereto, the water supply pipe being for supplying sample water; a housing part, the lid part being detachably attached to the housing part or the housing part being detachably attached to the lid part; and a filter part housed in the housing part and filtering the microorganisms from the sample water.

2 . The microorganism sampling device according to claim 1 , wherein
the lid part is a head part; the microorganism sampling device comprising: the housing part, the head part being detachably attached to an upper part thereof; and the filter part including a frame-structured tube body, a tubular filter arranged within the tube body, a cup communicating with the tubular filter and attached to one end of the tube body, and a cap having a channel communicating with the tubular filter and being attached to another end of the tube, the filter part being housed in the housing part, a bottom part of the cup being supported by a bottom part of the housing part; wherein the head part is attached to the upper part of the housing part so as to make the water supply channel of the head part and a channel of the cap communicate with each other, thereby allowing the sample water supplied from the water supply channel of the head part to be supplied into the tubular filter of the filter part.

3 . The microorganism sampling device according to claim 2 , wherein
the head part further has a water discharge channel allowing a water discharge pipe to be connected thereto, the water discharge pipe being for discharging the sample water; and the head part is attached to the upper part of the housing part so as to make the water discharge channel of the head part and a space outside the filter part communicate with each other, thereby allowing the sample water having passed through the tubular filter of the filter part to be discharged from the water discharge channel of the head part.

4 . The microorganism sampling device according to claim 2 , wherein
a discharge port for discharging concentrated water is provided on the bottom part of the cup, the concentrated water being such that microorganisms too large to pass through the tubular filter are concentrated, and a concentrated water discharge part for discharging the concentrated water from the discharge port of the cup is provided on the bottom part of the housing part.

5 . The microorganism sampling device according to claim 2 , wherein
a sample water drain part for draining the sample water remaining in the housing part is provided on the bottom part of the housing.

6 . The microorganism sampling device according to claim 2 , wherein
a rectifying part for swirling the sample water supplied into the tubular filter is provided within the channel of the cap.

7 . The microorganism sampling device according to claim 1 , wherein
the lid part is a base part; the housing part is detachably attached to an upper part of the base part; the base part includes an opening for supplying to an inside of the filter part the sample water supplied to the base part; the filter part has a tubular filter and a cup, the cup being attached so as to communicate with the tubular filter; the cup has an opening at a bottom part of the cup and the bottom part of the cup is supported by the base part; and the sample water is supplied from an opening provided on the base part to the inside of the filter part via the opening provided on the bottom part of the cup.

8 . The microorganism sampling device according to claim 1 , wherein
the lid part is a base part; the housing part is detachably attached to an upper part of the base part, the base part includes a pipe for supplying to an inside of the filter part the sample water supplied to the base part, the filter part has a tubular filter and a cup, the cup being attached so as to communicate with the tubular filter; and the cup has a through hole for inserting the pipe on a bottom part of the cup and the bottom part of the cup is supported by the base part.

9 . The microorganism sampling device according to claim 8 , wherein
the base part further has a water discharge channel allowing a water discharge pipe to be connected thereto, the water discharge pipe being for discharging the sample water having passed through the filter part; and the base part is attached to a lower part of the housing part so as to make the water discharge channel of the head part and a space outside the filter communicate with each other, thereby allowing the sample water having passed through the tubular filter of the filter part to be discharged from the water discharge channel of the base part.

10 . The microorganism sampling device according to claim 8 , wherein
the pipe includes an outflow port so as to discharge concentrated water from the cup, the concentrated water being such that microorganisms too large to pass through the tubular filter are concentrated; and the base part includes a concentrated water discharge part for discharging the concentrated water flowing out from the outflow port of the pipe.

11 . The microorganism sampling device according to claim 8 , wherein
the filter part includes a frame-structured tubular body provided on an inside of the tubular filter and supporting the tubular filter.

12 . A portable microorganism sampling device comprising a frame with a stand provided on a back surface; wherein the microorganism sampling device according to claim 1 is fixed to the frame.

13 . The microorganism sampling device according to claim 3 , wherein
a discharge port for discharging concentrated water is provided on the bottom part of the cup, the concentrated water being such that microorganisms too large to pass through the tubular filter are concentrated, and a concentrated water discharge part for discharging the concentrated water from the discharge port of the cup is provided on the bottom part of the housing part.

14 . The microorganism sampling device according to claim 3 , wherein
a sample water drain part for draining the sample water remaining in the housing part is provided on the bottom part of the housing.

15 . The microorganism sampling device according to claim 4 , wherein
a sample water drain part for draining the sample water remaining in the housing part is provided on the bottom part of the housing.

16 . The microorganism sampling device according to claim 3 , wherein
a rectifying part for swirling the sample water supplied into the tubular filter is provided within the channel of the cap.

17 . The microorganism sampling device according to claim 4 , wherein
a rectifying part for swirling the sample water supplied into the tubular filter is provided within the channel of the cap.

18 . The microorganism sampling device according to claim 5 , wherein
a rectifying part for swirling the sample water supplied into the tubular filter is provided within the channel of the cap.

19 . The microorganism sampling device according to claim 9 , wherein
the pipe includes an outflow port so as to discharge concentrated water from the cup, the concentrated water being such that microorganisms too large to pass through the tubular filter are concentrated; and the base part includes a concentrated water discharge part for discharging the concentrated water flowing out from the outflow port of the pipe.
