The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, 2 and 4, the faeces sampling device according to the first embodiment of the utility model comprises a tube 10, a sealing cap 20 and a scoop 30.

The pipe wall of the pipe body 10 is a cylindrical structure, the upper end surface of the cylindrical structure is an opening, the lower end surface of the cylindrical structure is a closed structure, specifically, the lower end surface can be a horizontal surface, or a conical surface can be adopted, and in this embodiment, the horizontal surface is preferred, so that the pipe body 10 can stand on a table top.

The sealing cover 20 is detachably connected to the opening of the pipe body 10, specifically, the sealing cover 20 includes a top plate 21, and a side plate 22 disposed at the outer periphery of the top plate 21, an internal thread 81 is disposed on an inner wall of the side plate 22, an external thread 82 adapted to the internal thread 81 is disposed on the pipe body 10, and the internal thread 81 and the external thread 82 can be mutually matched and locked, so that the sealing cover 20 is screwed on the pipe body 10.

The scoop 30 includes a first connecting rod 31, a second connecting rod 32, and a scoop head 33 with a fork 331, one end of the first connecting rod 31 is fixedly disposed on the inner side surface of the sealing cover 20, the other end is movably connected with the second connecting rod 32, the scoop head 33 is disposed at the end of the second connecting rod 32, the sum of the lengths of the first connecting rod 31 and the second connecting rod 32 is greater than the depth of the pipe body 10, and when the first connecting rod 31 and the second connecting rod 32 are folded to coincide, the scoop 30 can be accommodated in the pipe body 10.

Specifically, as shown in fig. 5, in this embodiment, the first connecting rod 31 is provided with a first connecting piece 41, the second connecting rod 32 is provided with a second connecting piece 42, the first connecting piece 41 is fixedly connected with the second connecting piece 42, and the first connecting piece 41 and the second connecting piece 42 are made of elastomer materials, so that the folding requirement between the first connecting rod 31 and the second connecting rod 32 can be met, and particularly, the elastomer materials include, but are not limited to, plastics.

Further, as shown in fig. 3, the second connecting rod 32 is provided with a bearing block 51, and the first connecting rod 31 is provided with a groove 52 engaged with the bearing block 51. In practical application, when the first connecting rod 31 and the second connecting rod 32 are unfolded to be horizontal, the bearing blocks 51 are attached to the inner surfaces of the grooves 52, so as to play a supporting role. Specifically, during sampling, fecal matter may exert a downward force on the scoop head 33, which is reversed by the bearing block 51 against the recess 52, thereby stabilizing the scoop 30 structure. In addition, in the present embodiment, the folding point of the first connecting rod 31 and the second connecting rod 32 is preferably located at the midpoint of the sum of the lengths of the first connecting rod 31, the second connecting rod 32 and the spoon head 33.

With continued reference to fig. 3, a convex hull 53 is disposed on two opposite sides of the bearing block 51, and a slot 54 corresponding to the convex hull 53 is disposed on the inner surface of the groove 52. When the first connecting rod 31 and the second connecting rod 32 are unfolded to be horizontal, the convex hulls 53 can be clamped into the corresponding clamping grooves 54, so that the scoop 30 is always kept in a vertical state. It should be noted that, in the present embodiment, the first connecting rod 31 and the second connecting rod 32 are also made of plastic, and have a certain elasticity, so the convex hull 53 can be clamped into the clamping groove 54.

It should be noted that, since the length of the scoop 30 after being unfolded is greater than the depth of the tube 10, after the sample is taken, the scoop 30 is difficult to fold due to the feces attached to the scoop head 33, which results in the sealing cover 20 not being screwed on the tube 10. To solve this problem, we provide a break point 60 on the first connecting rod 31, as shown in fig. 4. Specifically, in the process of placing the fecal sample into the tube body 10, the user can take the breaking point 60 on the first connecting rod 31 at the tube opening of the tube body 10 as a fulcrum, and then break the first connecting rod 31 slightly outwards with force, so that the second connecting rod 32 and part of the first connecting rod 31 are left in the tube body 10, and at this time, the sealing cover 20 is not affected by the length of the scoop 30, and can be easily screwed on the tube body 10.

In practical applications, when the user finishes sampling the feces, the sealing cover 20 is usually screwed and then sent for inspection, and after receiving the sample, the inspector usually needs to manually unscrew the sealing cover 20 and then inspect the feces sample, wherein the user inevitably needs to contact with the feces sample at a short distance or even at a zero distance during the operation, so that the inspector often feels nausea and regurgitation. To prevent this, a through hole 91 is formed in the top plate 21, and a protective film covering the through hole 91 is attached to the upper surface of the top plate 21, as shown in fig. 6. During detection, the sealing cover 20 does not need to be unscrewed, a detection person can directly insert the sampling needle into the tube body 10 through the protective film to absorb the sample, and then the sample is detected, so that the short-distance or even zero-distance contact with the fecal sample is avoided in the operation process.

It should be noted that, after the through hole 91 is formed in the top plate 21, the installation position of the first connecting rod 31 needs to be adjusted correspondingly, in this embodiment, the through hole 91 is preferably formed in the center of the top plate 21, so that the sampling needle is aligned, and the first connecting rod 31 is disposed at a position deviated from the through hole 91 so as to avoid the insertion of the sampling needle.

In summary, in the fecal sampling device according to the above embodiment of the present utility model, the scoop 30 is designed to be folded, so that the length of the scoop 30 is not limited by the depth of the test tube, when in use, a user can expand the first connecting rod 31 and the second connecting rod 32 of the scoop 30, increase the length of the scoop 30, facilitate the sampling of fecal specimens, and solve the technical problem that the length of the scoop 30 used for scooping fecal specimens in the prior art is limited by the length of the test tube, cannot be designed longer, and the fecal is difficult to scoop due to too short length of the scoop 30 when falling into the toilet water.

As shown in fig. 7, the second embodiment of the present utility model also discloses a fecal sampling device, which is different from the fecal sampling device of the first embodiment in that: the opening edge of the tube body 10 is provided with a bayonet 70, and the bayonet 70 is used for being matched with the breaking point 60 to break the first connecting rod 31. The specific operation is as follows: the breaking point 60 of the first connecting rod 31 is clamped into the bayonet 70, and then the sealing cover 20 is held to rotate clockwise or anticlockwise, so that the first connecting rod 31 can be broken off stably, the simplicity and stability of operation are improved, and the first connecting rod 31 is prevented from slipping at the edge of the pipe orifice due to uneven stress in the breaking process.

The third embodiment of the present utility model also discloses a fecal sampling device, which is different from the fecal sampling device in the first embodiment in that: the spoon head 33 and the second connecting rod 32 can also be folded. Accordingly, the length of the tube body 10 can be further shortened, thereby reducing the manufacturing cost of the tube body 10. The folding manner of the spoon head 33 and the second connecting rod 32 may be the same as the folding manner between the first connecting rod 31 and the second connecting rod 32, and thus, reference is made to the content of the first embodiment.
