Abstract

An excrement collector comprises an upper cover (100), a collecting tube (300), a bottom cover (400) and a filtering tube (200), wherein the filtering tube (200) is fixed on the upper side inside the tube cavity of the collecting tube (300); a sampling end (103) is formed on the lower part of the upper cover (100) and passes through a through hole (203) at the bottom of the filtering tube (200); the upper cover (100) is detachably integrated with the upper part of the collecting tube (300); the bottom cover (400) is detachably integrated with the lower part of the collecting tube (300); and liquid is provided in the cavity between the collecting tube (300) and the filtering tube (200).

Claims

1. An excrement collector, comprising:

an upper cover, a collecting tube, a bottom cover and a filtering tube, wherein the filtering tube is a funnel-shaped hollow tube and is fixed on the upper side inside the tube cavity of the collecting tube;

a sampling end is formed on the lower part of the upper cover and passes through a through hole at the bottom of the filtering tube;

the upper cover is detachably integrated with the upper part of the collecting tube;

the bottom cover is detachably integrated with the lower part of the collecting tube; and

liquid is provided in the cavity between the collecting tube and the filtering tube.

2. The excrement collector according to claim 1, wherein the filtering tube comprises a filtering tube body, an opening on the upper part of the filtering tube body, a through hole at the bottom of the filtering tube body, and a flange extending outwards from the top of the filtering tube body;

a pallet integrated with the flange is provided on the upper inner wall of the tube cavity of the collecting tube;

the filtering tube and the collecting tube are integrated together by the flange and the pallet;

preferably, the flange is bonded with the pallet; and

more preferably, the filtering tube is integrative.

3. The excrement collector according to claim 1 or 2, wherein the filtering tube body of the filtering tube comprises a main tube body and a joint face between the main tube body and the through hole;

the main tube body is cylindrical, and the outer diameter of the main tube body is larger than the inner diameter of the collecting tube;

preferably, the length of the main tube body is 1/2 to 4/5 of the length of the filtering tube body of the filtering tube;

more preferably, the filtering tube divides the collecting tube into two cavities, the cavity between the collecting tube and the filtering tube is a sample cavity, and the cavity where the collecting tube is superposed with the filtering tube is an observation cavity; and

most preferably, the length of the sample cavity is 1/2 to 3/4 of the length of the collecting tube.

4. The excrement collector according to claim 1, wherein the upper cover comprises a handle end, a sampling end and a sampling rod for connecting the handle end and the sampling end, and the length of the sampling rod is longer than the total length of the filtering tube;

preferably, the sampling end comprises a threaded part extending towards the handle end, and when the upper cover is integrated with the upper part of the collecting tube, the sampling end is placed in the liquid between the collecting tube and the filtering tube; and

more preferably, the outer diameter of the threaded part is equal to the diameter of the through hole.

5. The excrement collector according to claim 4, wherein the through hole is a hollow cylinder protruding away from the flange, and the diameter of the through hole is smaller than the diameter of the sampling rod.

6. The excrement collector according to claim 1, wherein the collecting tube comprises an inlet end, an outlet end and a tube body between the inlet end and the outlet end;

preferably, both the inlet end and the tube body are cylindrical, the diameter of the inlet end is larger than the diameter of the tube body, and the pallet is a joint face between the inlet end and the tube body; and

most preferably, the diameter of the outlet end is smaller than the diameter of the tube body.

7. The excrement collector according to claim 6, wherein the inlet end is in threaded connection with the handle end;

and preferably, the inlet end comprises an internal thread, and the handle end comprises an external thread corresponding to the internal thread.

8. The excrement collector according to claim 6 or 7, wherein the outlet end is in threaded connection with the bottom cover;

preferably, the outlet end comprises an external thread, and the bottom cover comprises an internal thread corresponding to the external thread; and

more preferably, an opening communicated with the outside is formed at the bottom of the outlet end and is sealed by a sealing membrane.

9. The excrement collector according to claim 1, wherein the bottom cover comprises a cylinder wall and a top wall, and the top wall is located on the cross section of the cylinder wall;

preferably, a spine component for puncturing the bottom of the collecting tube is provided in the center of the outer surface of the top wall;

more preferably, the length of the spine component is less than the height of the cylinder wall around the periphery of the spine component; and

most preferably, the inner diameter of the cylinder wall around the spine component is larger than the outer diameter of the outlet end, and the maximum diameter of the spine component is 1/5 to 1/2 of the inner diameter of the outlet end.

10. The excrement collector according to claim 1, wherein the collecting tube and the filtering tube are made of a transparent material;

and preferably, the collecting tube is mainly made of polyethylene or polypropylene, and the filtering tube is mainly made of polyethylene, or polypropylene, or silica gel.

11. A method for using the excrement collector according to claim 1, comprising the following steps:

a. removing the bottom cover on the lower part of the collecting tube, and

b. puncturing the bottom part of the collecting tube to drop the liquid in the collecting tube to an examination casse for examination; and

preferably, in the step b, the bottom part of the collecting tube is punctured by the spine component on the casse or the spine component on an examination machine.
