This novel shit sample collection device includes: the collecting tube 10 is provided with a collecting port 12, and the sealing plug 40 is matched with the shape of the collecting port 12 and detachably connected to the collecting port 12; the vacuum piston 20 is inserted into the collection tube 10 and movably arranged back and forth relative to the collection tube 10, and the vacuum piston 20 comprises a piston push rod 21 and a piston head 22 arranged at the end part of the piston push rod 21; the excrement detection spoon 30 is detachably connected with the piston head 22, and the excrement detection spoon 30 comprises a telescopic rod 31 and a spoon body 32 connected with the head end of the telescopic rod 31.

Specifically, the user adopts different collection modes according to the stool properties. If stool is formed, the vacuum piston 20 is withdrawn from the collection tube 10, the stool spoon 30 is removed, the telescoping rod 31 is extended, the stool spoon 30 is adjusted to the appropriate length, the stool specimen is scooped up with the stool spoon 30 and placed into the collection tube 10, and the vacuum piston 20 is inserted back into the collection tube 10 to seal the stool specimen. If the excrement is loose excrement, the vacuum piston 20 is pulled out of the collection tube 10, the excrement detection spoon 30 connected to the piston head 22 is detached, the vacuum piston 20 is inserted back into the collection tube 10, the sealing plug 40 connected to the collection port 12 is taken down, the piston push rod 21 is pressed to push the piston head 22 towards the collection port 12, air in the collection tube 10 is exhausted, then the collection port 12 is stretched into the loose excrement, the piston push rod 21 is pulled out of the collection tube 10 slowly, the loose excrement sample is sucked into the collection tube 10, and after a proper amount of the loose excrement sample is collected, the collection port 12 is sealed by the sealing plug 40.

First, referring to fig. 2 and 3, fig. 2 is a schematic structural view of the novel stool sample collection device according to some embodiments of the present invention when collecting formed stool, and fig. 3 is a schematic structural view of the novel stool sample collection device according to some embodiments of the present invention when collecting loose stool.

In order to conveniently collect the stool sample no matter whether the stool is formed or not so as to improve the efficiency of collecting the stool sample, the embodiment adopts the collecting tube 10 provided with the collecting port 12, the cross section of the collecting port 12 is smaller than that of the collecting tube 10, the vacuum piston 20 is inserted into the collecting tube 10 and is movably arranged back and forth relative to the collecting tube 10, and the vacuum piston 20 comprises a piston push rod 21 and a piston head 22 arranged at the head end part of the piston push rod 21; the fecal spoon 30 is removably attached to the piston head 22. Specifically, the user adopts different collection modes according to the stool properties, if the stool is formed, the stool examination spoon 30 in the collection tube 10 is taken out, the stool specimen is dug, if the stool is loose, the stool examination spoon 30 connected with the piston head 22 is detached, and the collection tube 10 is matched with the vacuum piston 20 to draw the loose stool specimen. Moreover, in order to facilitate the disassembly of the stool examination spoon 30, in some embodiments, the telescopic rod 31 and the piston head 22 of the stool examination spoon 30 are provided with matching thread structures.

It is noted that the fecal spoon 30 is attached to the piston head 22 and is inserted into the collection tube 10 along with the vacuum piston 20, and thus in this embodiment, the length of the fecal spoon 30 is less than the length of the collection tube 10. When collecting loose stools, it is necessary to remove the dipstick 30 and press the plunger push rod 21 to push the plunger head 22 to the collection port 12, so that in this embodiment, the length of the vacuum plunger 20 is greater than the length of the collection tube 10 so that the gas in the collection tube 10 can be completely evacuated. The collection port 12 is then extended into the thin stool, the vacuum piston 20 is slowly pulled out of the collection tube 10, and the thin stool specimen is drawn into the collection tube 10, so in this embodiment, the cross-section of the piston head 22 and the collection tube 10 is circular, and the diameter of the piston head 22 matches the inner diameter of the collection tube 10.

Secondly, in order to reduce the user's feeling of conflict in stool specimen collection, the embodiment employs an extensible stool examination spoon 30. The defecation detecting spoon 30 comprises a telescopic rod 31 and a spoon body 32 connected to the end part of the head of the telescopic rod 31, wherein the telescopic rod 31 comprises a fixed joint and an expansion joint inserted in the fixed joint, the fixed joint is detachably arranged relative to the vacuum piston 20, and the expansion joint is connected with the spoon body 32.

The structure of the vacuum piston 20 has been described in detail previously, and the sealing plug 40 is mainly described here. The sealing plug 40 in this embodiment matches the shape of the collection port 12 and is removably attached to the collection port 12. When the loose stool is collected, the sealing plug 40 needs to be taken down to stretch the collection port 12 into the loose stool, and after the collection of the loose stool sample is completed, the collection port 12 is sealed by the sealing plug 40. In some embodiments, the sealing plug 40 is made of rubber, which can provide a good sealing effect.

Particularly, in order to make the user better observe the collection amount when collecting the stool sample, in this embodiment, the collection tube 10 is designed to be transparent and has a volume scale 11 on the surface, and when in use, the user only needs to collect a proper amount of stool sample through the volume scale 11 on the collection tube 10.

In addition, the stool of part of patients is hard, and the ordinary circular arc-shaped spoon body 32 is inconvenient to dig and take stool samples, so in some embodiments, the edge of the spoon body 32 is provided with sawteeth, which is convenient for cutting hard stool.

Finally, in order to conveniently store the collection tube 10, the novel excrement sample collection device in the embodiment is provided with the device shell 50, the collection tube 10 is placed in the device shell 50, wherein the lower bottom surface of the device shell 50 is larger than the upper bottom surface, and the device can be placed more stably.

In summary, the novel stool sample collecting device in some embodiments provided by the present invention includes a collecting tube 10 and a sealing plug 40, which are provided with collecting ports 12, and according to the stool characteristics, a user can select two different collecting modes to collect stool samples by using the collecting tube 10, so as to improve the collecting efficiency of stool samples with different characteristics; the excrement detection spoon 30 capable of being lengthened is adopted, and the excrement detection spoon 30 is adjusted to be proper in length by adjusting the telescopic rod 31, so that the conflict emotion of a user on excrement sample collection is reduced; in addition, the vacuum piston 20 and the sealing plug 40 are also used for sealing the collection tube 10, so that the excrement sample is in a closed environment, the original characteristics of excrement are kept, and the detection accuracy of the excrement sample is further improved.

The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by anyone in the light of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as those of the present application, fall within the protection scope of the present invention.
