[0003] Currently, in general, a spoon is arranged in a sampling tube for a fecal collection device, and the lid is fixedly connected to the spoon. When a physical examinee samples feces, the lid is held and the feces are scooped up with the spoon, then the feces are put into the sampling tube, and finally the lid is screwed tightly with the sampling tube. However, since many physical examinees have shaky hands when putting the spoon into the sampling tube, the feces may fall on the ground or on the wall of the sampling tube, which not only causes hygiene problems, but also requires the physical examinee to resample, resulting in a poor experience effect. Summary of the Utility Model
[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a fecal sampling device, which can more stably prevent feces from falling off, not only avoids hygiene problems, but also avoids the phenomenon of resampling, thereby improving the user experience effect.
[0005] The purpose of the utility model is realized by adopting the following technical scheme:
[0006] A fecal sampling device, comprising:
[0007] A sampling tube, having a receiving cavity;
[0008] A lid, connected with a sampling rod, on the outer curved surface wall of the sampling rod, a spiral groove spirally extending along the length direction of the sampling rod is formed, the spiral groove is used for receiving feces, the sampling rod can be inserted into the receiving cavity, and the lid is adapted to the sampling tube to seal the receiving cavity.
[0009] Further, an anti-dropping barrier wall is arranged at the outer edge of the spiral groove, and the anti-dropping barrier wall is used to prevent feces from falling off from the inside to the outside along the radial direction of the sampling rod.
[0010] Further, the groove wall of the spiral groove is an arc surface structure.
[0011] Further, the cross-sectional outer contour of the end of the sampling rod far from the lid gradually increases along the cross-sectional outer contour of the end of the sampling tube close to the lid.
[0012] Further, a first rotation direction indicating line is provided on the outer end face of the lid, and the first rotation direction indicating line is used to guide the examiner to rotate the lid along the direction indicated by the first rotation direction indicating line, so as to spin the feces into the spiral groove.
[0013] Further, a protruding column is connected to the outer end face of the lid, the protruding column extends along the axial direction of the lid, and the protruding column is used for being grasped by hand.
[0014] Further, a second rotation direction indicating line is provided on the end face of the protruding column away from the lid, and the second rotation direction indicating line is used to guide the examiner to rotate the lid along the direction indicated by the second rotation direction indicating line, so as to spin the feces into the spiral groove.
[0015] Further, the protruding column has a polygonal prism structure.
[0016] Further, the sampling rod is of a transparent structure.
[0017] Further, the sampling tube is of a transparent structure.
[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0019] 1. By providing a spiral groove spirally extending along the length direction on the outer curved surface wall of the sampling rod, since the spiral groove can more covertly accommodate feces, after the sampling rod obtains feces, the feces are stably placed in the spiral groove, so it is not easy to fall off, which not only avoids hygienic problems, but also avoids the phenomenon of re-sampling, thereby improving the user experience effect.
[0020] 2. Moreover, even if the examiner's hand shakes during the process of inserting the sampling tube into the accommodating cavity, due to the feces being tightly adhered to the groove wall of the spiral groove, it is also difficult to fall off.
[0021] 3. In addition, since the feces are mainly carried by the sampling rod, when removing the sample from the sampling rod, it is not necessary to scoop out the feces from the accommodating cavity, thereby reducing the difficulty of taking out the sample and improving the inspection efficiency.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.
[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0030] Referring to Figures 1-4 , a fecal sampling device according to a preferred embodiment of the present utility model includes: a sampling tube 1 and a lid 2.
[0031] The sampling tube 1 has an accommodating cavity 11. The accommodating cavity can not only easily prevent feces from falling on the ground but also be used as one of the carriers for accommodating feces.
[0032] The lid 2 is connected with a sampling rod 21. A spiral groove 211 extending spirally along the length direction of the sampling rod 21 is provided on the outer curved surface wall of the sampling rod 21. The spiral groove 211 is used to accommodate feces. The sampling rod 21 can be inserted into the accommodating cavity 11 to temporarily store feces in the accommodating cavity; the lid 2 is adapted to the sampling tube 1 to seal the accommodating cavity 11 to prevent the malodorous gas generated by feces from escaping outside the sampling tube 1, thereby polluting the indoor environment.
[0033] Among them, the lid 2 and the sampling tube 1 can be integrally injection-molded, or can be fixed together by snap connection or screw connection, or can also be fixed to each other by insertion and interference fit.
[0034] Among them, the lid 2 and the sampling tube 1 can be locked by transition fit or interference fit, or can be locked by threaded connection, or can also be locked by mortise and tenon structure.
[0035] It can be understood that the outer side of the spiral groove 211 on the sampling rod 21 is a notch, and the notch extends spirally along the length direction of the sampling tube 1. When loading the sample into the sampling rod 21, the notch is used for feces to enter the spiral groove 211 from the outside to the inside along the radial direction of the sampling rod 21. And when taking the sample off the sampling rod 21, the notch is used for feces to be taken out from the inside to the outside along the radial direction of the sampling rod 21. In addition, the spiral groove 211 is used to temporarily and reliably store feces until the sample needs to be taken off the sampling rod 21.
[0036] When the sampling rod 21 is sampling, a person holds the lid 2 to insert the sampling rod 21 into the feces, then rotates the lid 2 so that the feces are screwed into the spiral groove 211, and then holds the lid 2 to retract the sampling rod 21, and then loads the sampling rod 21 with the collected feces into the accommodation cavity 11.
[0037] When taking the sample off the sampling rod 21, insert a disposable spoon in the inspection room into the spiral groove 211 along the notch of the spiral groove 211, and then rotate the lid 2 to take the feces off the sampling rod 21, and then inspect the sample.
[0038] Obviously, by providing a spiral groove 211 that spirally extends along the length direction on the outer curved surface wall of the sampling rod 21, since the spiral groove 211 can more covertly accommodate feces, after the sampling rod 21 obtains feces, the feces are stably placed in the spiral groove 211, so it is not easy to fall off, which not only avoids hygienic problems, but also avoids the phenomenon of re-sampling, thus improving the user experience effect. Moreover, even if the examinee's hand shakes during the process of inserting the sampling tube 1 into the accommodation cavity 11, due to the feces being tightly adhered to the groove wall of the spiral groove 211, it is also difficult to fall off. In addition, since the feces are mainly carried by the sampling rod 21, when taking the sample off the sampling rod 21, there is no need to scoop out the feces from the accommodation cavity 11, thus reducing the difficulty of taking out the sample to improve the inspection efficiency.
[0039] In one embodiment, an anti - shedding barrier 212 is provided at the outer edge of the spiral groove 211, that is, an anti - shedding barrier 212 is provided at the notch of the groove. The anti - shedding barrier 212 is used to prevent feces from falling off radially from the inside to the outside along the sampling rod 21. It can be understood that the anti - shedding barrier 212 is equivalent to the function of a dam. With this setting, when the examinee has a severe hand - shaking phenomenon, since the feces in the spiral groove 211 are reliably intercepted, it is more difficult to cross the notch radially from the inside to the outside along the sampling rod 21, so it is even more difficult for feces to fall to the ground, thus avoiding unnecessary cleaning work and the need for the examinee to re - sample, and further improving the user experience effect.
[0040] In one embodiment, the groove wall of the spiral groove 211 is an arc - surface structure. With this setting, when removing the sample from the sampling rod 21, a disposable spoon in the testing room is inserted into the spiral groove 211 along the notch of the spiral groove 211. The disposable spoon contacts the groove wall of the spiral groove 211 smoothly, so that when rotating the lid 2, the feces can be removed from the sampling rod 21 more smoothly, and then the sample is tested. It can be understood that in other embodiments, the groove wall of the spiral groove 211 can also be a planar structure. For example, the outer contour of the cross - section of the spiral groove 211 is a V - shaped structure or a right - angled U - shaped structure.
[0041] In one embodiment, the cross - sectional outer contour of the end of the sampling rod 21 far from the lid 2 gradually increases along the cross - sectional outer contour of the end of the sampling tube 1 close to the lid 2. With this setting, that is, the outer contour of the sampling rod 21 is a frustum - of - a - cone structure. The advantage of this setting is that when the sampling rod 21 samples, a person holds the lid 2 to insert the sampling rod 21 into the feces, and then rotates the lid 2 so that the feces are screwed into the spiral groove 211. Then, hold the lid 2 to retract the sampling rod 21. During the retraction process, since the diameter of the sampling rod 21 gradually decreases, it will not drag other feces out together, so as to avoid excess feces sticking to the sampling rod 21. In addition, when loading the sampling rod 21 with collected feces into the accommodating cavity 11, based on the smaller diameter of the end of the sampling rod 21 far from the lid 2, it is more convenient to align with the pipe orifice of the sampling tube 1, so as to smoothly insert the sampling rod 21 into the accommodating cavity 11.
[0042] In one embodiment, a first rotation - direction indication line 22 is provided on the outer end face of the lid 2. The first rotation - direction indication line 22 is used to guide the examinee to rotate the lid 2 along the direction indicated by the first rotation - direction indication line 22 to screw the feces into the spiral groove 211. Among them, the guiding direction of the first rotation - direction indication line 22 is the same as the direction of loading feces into the spiral groove 211, so as to prompt the examinee to correctly load the feces into the spiral by following this direction, thereby improving the sampling efficiency of the examinee and ensuring the user experience effect.
[0043] In one embodiment, a protruding column 23 is connected to the outer end face of the lid 2. The protruding column 23 extends along the axial direction of the lid 2 and is used for being gripped by a human hand to prevent the lid 2 from falling off the human hand during the process of rotating the lid 2 by the human hand. Further, in order to further prevent the lid 2 from falling off, the protruding column 23 has a polygonal prism structure. During the process of the human hand rotating the protruding column 23, the polygonal prism structure provides the stability of rotating at a fixed angle, making it more difficult for the lid 2 to fall off the human hand.
[0044] In one embodiment, a second rotation direction indication line 24 is provided on the end face of the protruding column 23 away from the lid 2. The second rotation direction indication line 24 is used to guide the examiner to rotate the lid 2 along the direction indicated by the second rotation direction indication line 24 so as to screw the feces into the spiral groove 211. The function of the second rotation direction indication line 24 is the same as that of the first rotation direction indication line 22. The second rotation direction indication line 24 is continuously provided on the protruding column 23 so that the examiner can correctly rotate the lid 2 whether noticing the first rotation direction indication line 22 or the second rotation direction indication line 24.
[0045] In one embodiment, the sampling rod 21 has a transparent structure. With such a setting, it is beneficial for the examiner to identify whether the spiral groove 211 of the sampling rod 21 has collected a sufficient amount of feces. It can be understood that in other embodiments, the sampling rod 21 has a non-transparent structure.
[0046] In one embodiment, the sampling tube 1 has a transparent structure for the examiner to identify whether the sampling rod 21 is correctly inserted into the accommodation cavity 11. It can be understood that in other embodiments, the sampling tube 1 has a non-transparent structure.
[0047] The above embodiments are only the preferred embodiments of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model all belong to the protection scope required by the present utility model.
