Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a stool sampling rod, a stool sampling and collecting device, and a stool sampling and processing device. Background Art

[0002] Stool testing is of great significance in the early screening of certain diseases. For example, by testing the hemoglobin in the stool, it is possible to screen whether the patient has gastrointestinal bleeding. Therefore, stool testing has become a routine item for disease detection in many medical institutions.

[0003] In the existing stool testing process, the patient first collects a stool sample into a stool collection device, and then medical personnel take a sample of the liquid in the sampling tube for testing or place the stool sample in the stool collection device into a special stool testing device for testing.

[0004] Specifically, a conventional stool collection device generally includes a sampling rod and a sampling bottle used in conjunction with the sampling rod. When sampling stool, the sampling rod is first inserted into the stool to adhere a certain amount of stool sample, and then the sampling rod is inserted into the sampling bottle to place the obtained stool sample in the sampling bottle; the sampling bottle contains a protective liquid, which can be fully mixed and diluted with the stool sample by shaking or centrifugation to form a sample liquid mixed with the stool sample and the protective liquid. Finally, medical personnel perform sampling and testing on the sample liquid in the sampling bottle.

[0005] In conventional feces sampling devices, the sampling rod is fixed to the sampling bottle by means of threaded fitting, etc., and the protective liquid and the feces sample are fully mixed and diluted by shaking or centrifugation. When sampling and testing the sample liquid in the sampling bottle, the sampling rod needs to be removed and the sample liquid is then aspirated from the inside of the sampling bottle. After collecting the sample liquid, the sampling rod needs to be put back into the sampling bottle. Therefore, the process of collecting the sample liquid is relatively cumbersome. In addition, during the process of collecting the sample liquid, the tester is likely to come into contact with the sample liquid or drop or spill the sample liquid on the test bench or instrument, causing unnecessary contamination. In addition, since the sampling bottle needs to be opened for collecting the sample liquid, when the sampling bottle is opened, the odor of the sample liquid in the sampling bottle is emitted outward, causing discomfort to the tester.

[0006] Therefore, it is necessary to improve the existing stool sampling protocol. Summary of the Invention

[0007] In order to overcome at least one of the above-mentioned defects of the prior art, the first object of the present invention is to provide a stool sampling rod to solve the problem of inconvenience in collecting the sample liquid to be tested in the stool sampling scheme of the prior art.

[0008] In order to overcome at least one of the defects of the prior art described above, a second object of the present invention is to provide a stool sampling and collection device to solve the problem of inconvenience in collecting the sample liquid to be tested in the stool sampling scheme of the prior art.

[0009] In order to overcome at least one of the defects of the prior art, the third object of the present invention is to provide a stool sampling and processing device to solve the problem of inconvenience in collecting the sample liquid to be tested in the stool sampling scheme of the prior art.

[0010] The technical solution adopted by the present invention to solve the problem is:

[0011] According to one aspect of an embodiment of the present invention, a stool sampling rod is provided, comprising a first end and a second end for inserting into stool to collect a stool sample, and further comprising a sample liquid flow channel, the sample liquid flow channel being provided with a sample liquid inlet and a sample liquid outlet, wherein the sample liquid outlet is located at the first end, and the sample liquid inlet is connected to the interior of a sampling bottle for inserting the second end, so that the liquid in the sampling bottle can be transported to the sample liquid outlet through the sample liquid inlet and the sample liquid flow channel.

[0012] According to another aspect of an embodiment of the present invention, a stool sampling device is provided, comprising the above-mentioned stool sampling rod and a sampling bottle, wherein the second end of the stool sampling rod can be inserted into the sampling bottle.

[0013] According to another aspect of an embodiment of the present invention, a stool sampling and processing device is provided, comprising the above-mentioned stool sampling and collection device, and a workbench, wherein the workbench is provided with a receiving slot for placing a sampling bottle, and the workbench is also provided with a liquid collection device, which acts on a stool sampling rod or a sampling bottle to transport the sample liquid in the sampling bottle to the sample liquid outlet through the sample liquid flow channel.

[0014] It can be seen from the above technical solutions that the embodiments of the present invention have at least the following advantages and positive effects:

[0015] 1. Provide a stool sampling rod. By providing a sample liquid flow channel inside the rod, liquid in a sampling bottle inserted into the second end of the stool sampling rod can be transported through the sample liquid inlet and the sample liquid flow channel to the sample liquid outlet. Finally, the sample liquid can be collected at the sample liquid outlet, thereby improving the convenience of sample liquid collection, reducing the possibility of sample liquid contamination to the tester or the test platform during the sample liquid collection process, and also helping to reduce the discomfort caused to the tester by the odor of the stool sample.

[0016] 2. Provide a stool sampling and collection device. By setting a sample liquid flow channel inside the stool sampling rod, during sampling, the liquid in the sampling bottle can be transported through the sample liquid inlet and the sample liquid flow channel to the sample liquid outlet. Finally, the sample liquid can be collected at the sample liquid outlet on the stool sampling rod, thereby improving the convenience of sample liquid collection, reducing the possibility of sample liquid contamination to the tester or the test platform during the sample liquid collection process, and also helping to reduce the discomfort caused to the personnel by the smell of the stool sample;

[0017] 3. Provide a stool sampling and processing device. After the stool sample is sampled and collected by the stool sampling and collection device, the liquid collection device acts on the stool sampling rod or sampling bottle, so that the sample liquid in the sampling bottle enters from the sample liquid inlet and is transported to the sample liquid outlet through the sample liquid flow channel. Finally, the sample liquid can be collected at the sample liquid outlet on the stool sampling rod, thereby improving the convenience of sample liquid collection, reducing the possibility of sample liquid contaminating the testing personnel or the testing platform during the sample liquid collection process, and also helping to reduce the discomfort caused to personnel by the odor of the stool sample.

Therefore, they cannot be understood as limiting the present invention.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] Example 1

[0037] See Figures 1 to 3 as well as Figures 7 to 9 The present invention discloses a stool sampling rod 1, comprising a first end 11 and a second end 12, wherein the first end 11 and the second end 12 are integrally formed or fixedly connected, the first end 11 is for a stool sampler to grasp, and the second end 12 is used to be inserted into stool to collect a stool sample.

[0038] Preferably, at least the second end 12 can be immersed below the surface of the liquid 3 in the sampling bottle 2 for inserting the second end 12 of the feces sampling rod 1, so that the feces sample collected on the second end 12 can be mixed with the liquid 3 pre-stored in the sampling bottle 2, such as the protective liquid, to form the sample liquid to be tested.

[0039] Of course, even if the second end 12 is not immersed below the liquid surface of the liquid 3 in the sampling bottle 2, the stool sample and the liquid 3 can be mixed by shaking, rotating, pouring, etc. so that the liquid in the sampling bottle 2 contacts the second end 12.

[0040] In the present application, the stool sampling rod 1 also includes a sample liquid flow channel 13, which is provided with a sample liquid inlet 131 and a sample liquid outlet 132, wherein the sample liquid outlet 132 is arranged at the first end 11, and the sample liquid inlet 131 is arranged to be connected to the sampling bottle 2 so that the liquid 3 in the sampling bottle 2 can be transported to the sample liquid outlet 132 through the sample liquid inlet 131 and the sample liquid flow channel 13.

[0041] Thus, when the stool sampling rod 1 is placed in the sampling bottle 2, the stool collected through the second end 12 is mixed with the liquid 3 in the sampling bottle 2 to form a sample liquid. When collecting the sample liquid, since the sample liquid flow channel 13 is provided in the stool sampling rod 1, and the sample liquid inlet 131 of the sample liquid flow channel 13 is provided in the sampling bottle 2, and the sample liquid outlet 132 is provided at the first end 11, the liquid 3 in the sampling bottle 2 can be transported to the sample liquid outlet 132 through the sample liquid inlet 131 and the sample liquid flow channel 13 by means of, but not limited to, pouring, extracting or squeezing, and finally the sample liquid can be collected at the sample liquid outlet 132.

[0042] Preferably, the sample liquid flow channel 13 is provided in the stool sampling rod 1 .

[0043] See Figure 9In some possible embodiments, the sample liquid inlet 131 is arranged below the liquid surface in the sampling bottle 2; such a structural arrangement enables the sample liquid in the sampling bottle 2 to quickly enter the sample liquid flow channel 13 through the sample liquid inlet 131 when collecting the sample liquid, and then be transported to the sample liquid outlet 132, so as to improve the efficiency of sample liquid collection.

[0044] Of course, in other possible embodiments, the sample liquid inlet 131 is arranged above the liquid level in the sampling bottle 2, that is, when the sample liquid is not collected in the sampling bottle 2 in a static state, the sample liquid inlet 131 is located above the liquid level in the sampling bottle 2. When the sample liquid needs to be collected, the liquid 3 in the sampling bottle 2 is poured, extracted or squeezed to pass through the sample liquid inlet 131 and the sample liquid flow channel 13 to the sample liquid outlet 132, and finally the sample liquid is collected at the sample liquid outlet 132.

[0045] In the present application, the stool sampling rod 1 is in the shape of a long strip, and the present application does not limit its cross-sectional shape and size. For example, the stool sampling rod 1 may be cylindrical, and its cross-section may be circular, elliptical or polygonal, etc. When the cross-section of the stool sampling rod 1 is circular, its outer diameter is the diameter of the circle; when the cross-section of the stool sampling rod 1 is elliptical or polygonal, etc., the outer diameter of the stool sampling rod 1 is the maximum diameter of its cross-section.

[0046] In some possible embodiments, the outer diameter of the stool sampling rod 1 may remain consistent along the shaft direction.

[0047] In some other possible embodiments, it can also be configured as follows: the outer diameter of the stool sampling rod 1 is configured as a variable diameter, for example, see Figure 1 The outer diameter of the stool sampling rod 1 gradually decreases from the end portion thereof inserted into the sampling bottle 2 toward the other end thereof (i.e., from the second end 12 toward the first end 11), so that at least a portion of the second end 12 of the stool sampling rod 1 is tapered. This structural arrangement facilitates the insertion of the stool sampling rod 1 into the stool to be sampled or into the sampling bottle 2.

[0048] See Figure 2 、 Figure 3 In some possible embodiments, the sample liquid flow channel 13 is opened in a direction parallel to the rod body of the stool sampling rod 1, and the sample liquid inlet 131 and the sample liquid outlet 132 are respectively located at both ends of the sample liquid flow channel 13, and the opening directions of the sample liquid inlet 131 and the sample liquid outlet 132 are both collinear with the opening direction of the sample liquid flow channel 13; such a structural setting can simplify the processing technology and facilitate the production and manufacturing of the stool sampling rod 1.

[0049] Of course, in other possible embodiments, the opening direction of the sample liquid flow channel 13 forms an angle with the rod body direction of the stool sampling rod 1, and / or the opening direction of the sample liquid inlet 131 and / or the sample liquid outlet 132 forms an angle with the direction of the sample liquid flow channel 13. For example, the sample liquid inlet 131 and / or the sample liquid outlet 132 can be opened in a direction perpendicular to the sample liquid flow channel 13.

[0050] See Figure 1 、 Figure 8 In some possible implementations, an anti-slip pattern 112 is provided on the outer surface of the first end 11 of the stool sampling rod 1 to facilitate gripping the stool sampling rod 1 for stool sampling or separating or assembling the stool sampling rod 1 from the sampling bottle 2.

[0051] See Figures 1 to 3 In some embodiments, the stool sampling rod 1 of the present application further includes a filter element 14, wherein the filter element 14 is arranged in the sample liquid flow channel 13, and the filter element 14 is used to filter the liquid 3 entering from the sample liquid inlet 131 and flowing out from the sample liquid outlet 132; thus, when collecting the sample liquid, when the sample liquid in the sampling bottle 2 is taken out through the sample liquid flow channel 13 by pouring, extracting, squeezing, etc., the filter element 14 can filter the sample liquid, on the one hand to meet the requirements of sampling and detection, and on the other hand to reduce the large particles in the stool sample from flowing out with the sample liquid to cause pollution or a large odor emission.

[0052] The present application does not limit the shape, material and structure of the filter element 14. It only needs to meet the requirements for filtering large particles in the sample liquid. The specific filtering requirements depend on the requirements of sampling and testing. For example, filter cotton and / or filter mesh can be used.

[0053] The present application does not limit the installation position of the filter element 14 . For example, the filter element 14 can be installed at the sample liquid inlet 131 , the sample liquid outlet 132 , or any position in the middle of the sample liquid flow channel 13 .

[0054] In addition, the number of the filter elements 14 is not limited in this application, and one or more filter elements 14 may be provided.

[0055] See Figure 1 To facilitate the installation of the filter element 14 on the feces sampling rod 1, the dimension D2 of one end of the filter element 14 is smaller than the dimension D1 of the other end, so that the filter element 14 is truncated cone or prism-shaped as a whole.

[0056] See Figure 2 、 Figure 3 、 Figure 9In some embodiments, a sample liquid collecting groove 111 connected to the sample liquid outlet 132 is provided on the first end 11, and the diameter of the sample liquid collecting groove 111 is larger than the diameter of the sample liquid outlet 132; by providing the sample liquid collecting groove 111, on the one hand, the storage space at the sample liquid outlet 132 is expanded, which is convenient for accumulating sufficient sample liquid for sampling; on the other hand, the working space for sample liquid sampling is expanded, which is convenient for detection personnel to collect sample liquid.

[0057] In some possible embodiments, in addition to being disposed at any position in the sample liquid flow channel 13 , the filter element 14 may also be disposed in the sample liquid collection tank 111 to filter the liquid 3 flowing out of the sample liquid flow channel 13 .

[0058] See Figures 1 to 3 In some embodiments, a sampling groove 121 is provided on the second end 12, and the sampling groove 121 is opened on the outer surface of the rod body of the stool sampling rod 1 in the circumferential direction; in this embodiment, when sampling a stool sample, the second end 12 is inserted into the feces to be sampled, and the stool sample is accommodated and collected by the sampling groove 121 located on the outer circumferential surface of the rod body of the stool sampling rod 1, so that when the stool sampling rod 1 is pulled out from the stool body, the second end 12 can smoothly obtain the feces sample.

[0059] In this embodiment, the shape and arrangement of the sampling groove 121 are not limited. For example, the cross-sectional shape of the sampling groove 121 can be, but is not limited to, circular, triangular, trapezoidal, etc. The sampling groove 121 can be arranged in a circle perpendicular to the shaft of the feces sampling rod 1 and in multiple rows at intervals.

[0060] See Figure 1 , and can also be arranged spirally along the shaft direction of the feces sampling rod 1.

[0061] In addition, the sampling slots 121 may be arranged continuously or intermittently.

[0062] In some possible embodiments, the stool sampling rod 1 of the present application may further include a sealing film (not shown in the figure), which may be provided at the sample liquid inlet 131 , the sample liquid outlet 132 or the sample liquid collection groove 111 .

[0063] A sealing film is provided at the sample liquid inlet 131 to avoid the possibility of the feces sample clogging the sample liquid inlet 131 during the feces sampling process. After the feces sample is collected, the sealing film is pierced by a needle or other component with a pointed end, thereby opening the sample liquid flow channel 13 for subsequent removal of the sample liquid.

[0064] A sealing film is provided at the sample liquid outlet 132 or the sample liquid collecting groove 111, and during the process of shaking the sample liquid in the sampling bottle 2, the sealing film can prevent the liquid 3 from overflowing from the sample liquid collecting groove 111. After the shaking work is completed, the sealing film is pierced by a needle or other component with a pointed end, so that the subsequent sample liquid can be collected in the sample liquid collecting groove 111.

[0065] In addition, when the filter element 14 is disposed close to the sample liquid inlet 131 , a sealing film may be covered on the surface of the filter element 14 facing the sample liquid inlet 131 .

[0066] Similarly, when the filter element 14 is disposed close to the sample liquid outlet 132 or the sample liquid collecting groove 111 , the sealing film can be covered on the surface of the filter element 14 facing the sample liquid outlet 132 or the sample liquid collecting groove 111 .

[0067] The connection methods of the sealing film and the stool sampling rod 1 or the sealing member include but are not limited to bonding and integral molding.

[0068] Example 2

[0069] See Figures 4 to 6 、 Figures 11 to 13 The present invention discloses another stool sampling rod 1. Based on Example 1, the difference between this embodiment and Example 1 is only that:

[0070] In this embodiment, the sampling groove 121 is opened at the end of the second end 12 and extends from the second end 12 to the first end 11 along the rod direction of the stool sampling rod 1. The side of the stool sampling rod 1 is also provided with a plurality of sample inlet holes 15 connected to the sampling groove 121. The sampling groove 121 matches the shape of the lifting protrusion 202 provided in the sampling bottle 2 used with the stool sampling rod 1, so that the lifting protrusion 202 can be inserted into the sampling groove 121 to push the stool sample, so that the stool sample leaves the sampling groove 121 through the sample inlet holes 15.

[0071] The structure of the stool sampling rod 1 of this embodiment can, on the one hand, increase the amount of stool sample collected. On the other hand, since the sampling groove 121 can match the lifting protrusion 202 in the sampling bottle 2, after the stool sample is collected, the stool sampling rod 1 is inserted into the sampling bottle 2, and the lifting protrusion 202 can be inserted into the sampling groove 121 to push the stool sample through the sample inlet hole 15, so that the stool sample can be easily separated from the stool sampling rod 1 and fully mixed with the liquid 3 in the sampling bottle 2, thereby reducing the residue of the stool sample in the stool sampling rod 1.

[0072] Therefore, the stool sampling rod 1 of this embodiment can solve the technical problems of insufficient sampling volume and difficulty in separating the stool sample from the sampling slot 121 or the presence of a large amount of residue.

[0073] See Figure 5In some possible embodiments, the sample liquid inlet 131 is connected to the sampling groove 121, so that the mixed sample liquid can enter the sample liquid inlet 131 through the sampling groove 121 and then be discharged from the sample liquid outlet 132 through the sample liquid flow channel 13. In addition, when the stool sampling rod is inserted into feces and the feces sample is accommodated by the sampling groove 121, the sample inlet through hole 15 can be used for exhaust during the process of collecting the feces sample.

[0074] Of course, with this solution, when the lifting protrusion 202 is inserted into the sampling groove 121 to push the feces sample, the feces sample is easily pushed into the sample liquid inlet 131 , and may even block the sample liquid flow channel 13 .

[0075] Therefore, as a more preferred embodiment, a mounting groove 16 is further provided in the stool sampling rod 1, and the mounting groove 16 is for installing the filter element 14. The filter groove is connected to the sampling groove 121 and is away from the end of the stool sampling rod 1 at this end, so that under the filtering and blocking effect of the filter element 14, the pushing protrusion 202 can be prevented from being inserted into the sampling groove 121 to squeeze the stool sample, thereby preventing the stool sample from entering the sample liquid inlet 131 and blocking the sample liquid flow channel 13.

[0076] Furthermore, in order to reduce the obstacles to liquid discharge, when the feces sampling rod 1 is inserted into the sampling bottle 2 and fixed to the sampling bottle 2, a gap is maintained between the top material protrusion 202 and the surface of the filter element 14, so that enough space can be left for the sample liquid to pass through the filter element 14 and enter the sample liquid inlet 131.

[0077] See Figures 4 to 6 、 Figure 13 In some possible embodiments, a liquid collection hole 17 connected to the mounting groove 16 is opened on the side of the stool sampling rod 1. When the stool sampling rod 1 is inserted into the sampling bottle 2 and fixed to the sampling bottle 2, the lifting protrusion 202 is in contact with the surface of the filter element 14 or maintains a gap; at this time, since the liquid collection hole 17 is opened on the side of the stool sampling rod 1, when the sampling bottle 2 is squeezed, the sample liquid is squeezed out of the sampling bottle 2 through the liquid collection hole 17 and the side of the filter element 14, so that the sample liquid can smoothly enter the sample liquid flow channel 13.

[0078] In some possible embodiments, the sample liquid inlet 131 is not connected to the sampling tank 121 , so that during the stool sampling process, the stool sample entering the sampling tank 121 cannot enter the sample liquid inlet 131 and cause blockage of the sample liquid flow channel 13 .

[0079] Example 3

[0080] See Figures 7 to 9 The present invention discloses a stool sampling and collecting device, comprising a stool sampling rod 1 according to any one of the embodiments 1 and a sampling bottle 2, wherein the second end of the stool sampling rod can be inserted into the sampling bottle 2.

[0081] Furthermore, a cavity 200 is provided in the sampling bottle 2, and a quantitative limiting hole 201 is provided on the cavity 200 for the feces sampling rod 1 to be inserted into the sampling bottle 2. The cavity 200 of the sampling bottle 2 can be pre-filled with liquid 3, such as protective liquid. The feces sampling rod 1 after collecting the feces sample can be inserted into the sampling bottle 2 through the quantitative limiting hole 201.

[0082] Preferably, at least the second end 12 of the stool sampling rod 1 can be immersed below the liquid surface of the sampling bottle 2, and then the stool sample and the liquid 3 in the sampling bottle 2 can be shaken to form a sample liquid.

[0083] Since the improved stool sampling rod 1 in Example 1 is used, when collecting the sample liquid in the sampling bottle 2, since the sample liquid flow channel 13 is provided in the stool sampling rod 1, and the sample liquid inlet 131 of the sample liquid flow channel 13 is provided in the sampling bottle 2, and the sample liquid outlet 132 is provided at the first end 11, the liquid 3 in the sampling bottle 2 can be transported to the sample liquid outlet 132 through the sample liquid inlet 131 through the sample liquid flow channel 13 by means of, but not limited to, pouring, extracting or squeezing, and finally the sample liquid can be collected at the sample liquid outlet 132 without having to separate the stool sampling rod 1 from the sampling bottle 2 before sampling, and the trouble of reinstalling the stool sampling rod 1 back into the sampling bottle 2 after collecting the sample liquid is reduced. Therefore, the convenience of collecting the sample liquid in the sampling bottle 2 is improved, the possibility of contamination to the testing personnel or the testing platform during the sample liquid collection process is reduced, and it is also beneficial to reduce the odor of the stool sample in the sampling bottle 2 and the discomfort caused to the personnel.

[0084] To facilitate taking out the sample liquid in the sampling bottle 2 through the sample liquid flow channel 13 , in some possible embodiments, the internal volume of the sampling bottle 2 can be reduced to squeeze the sample liquid in the sampling bottle 2 out of the sampling bottle 2 through the sample liquid flow channel 13 .

[0085] Furthermore, in some possible embodiments, at least a portion of the sampling bottle 2 is deformable, so that after external pressure is applied to the deformable portion of the sampling bottle 2, the internal volume of the sampling bottle 2 can be reduced and the internal air pressure of the sampling bottle (2) can be increased, and then the sample liquid in the sampling bottle 2 can be squeezed out of the sampling bottle 2 through the sample liquid flow channel 13.

[0086] Furthermore, as a preferred embodiment, the deformation of the sampling bottle 2 is elastic deformation, so that when the external pressure applied to the sampling bottle 2 is eliminated, the elastically deformed portion of the sampling bottle 2 can automatically restore the deformation.

[0087] For example, in some possible embodiments, a portion of the sampling bottle 2 is set to be rigid, while another portion is set to be an elastic deformation portion that can be elastically deformed by being squeezed. For example, the portion of the sampling bottle 2 that is in contact with the protective liquid can be set to be made of an elastic material, while the remaining portion is made of a rigid material. In this way, the internal volume of the sampling bottle 2 can be reduced by squeezing the elastic deformation portion, thereby squeezing the liquid 3 inside it out of the sample liquid flow channel 13.

[0088] Alternatively, in some possible embodiments, the sampling bottle 2 can be configured as a whole to be elastically deformable, that is, the sampling bottle 2 is made of an elastic material, such as elastic plastic, and the internal volume of the sampling bottle 2 is reduced by squeezing the tube wall of the sampling bottle 2, and the liquid 3 inside it is squeezed out through the sample liquid flow channel 13.

[0089] Of course, in some possible embodiments, the deformed portion of the sampling bottle 2 is plastic deformation, that is, when the deformable portion of the sampling bottle 2 is squeezed by external pressure, the deformed portion deforms so that the volume inside the sampling bottle 2 is reduced, thereby squeezing out the sample liquid in the sampling bottle 2. When the external pressure applied to the sampling bottle 2 is eliminated, the deformed portion of the sampling bottle 2 cannot automatically rebound and maintain the deformed state.

[0090] In other embodiments, in order to reduce the volume of the sampling bottle 2, the sampling bottle 2 includes a fixed wall 2a and a movable wall 2b, wherein the movable wall 2b can move relative to the fixed wall 2a, and the fixed wall 2a and the movable wall 2b form a cavity 200 of the sampling bottle, and the movable wall 2b is sealed to the fixed wall 2a to prevent leakage from occurring in the movable gap between the movable wall 2b and the fixed wall 2a. Figure 10 As shown, in this embodiment, the entire sampling bottle 2 is similar to the structure of a piston or a syringe. By applying pressure to the movable wall 2b, the movable wall 2b is driven to move toward the inside of the cavity 200, thereby reducing the internal volume formed by the movable wall 2b and the fixed wall 2a, thereby achieving the purpose of squeezing the sample liquid in the sampling bottle 2 through the sample liquid flow channel 13.

[0091] As a preferred embodiment, an extrusion structure (not shown in the figure) can be provided corresponding to the sampling bottle 2. Specifically, the extrusion structure is connected to the movable wall 2b and can drive the movable wall 2b to move relative to the fixed wall 2a, so as to reduce the internal volume of the sampling bottle 2 and squeeze out the liquid 3 in the sampling bottle 2 through the sample liquid flow channel 13, that is, push the liquid in the sampling bottle 2 to be transported to the sample liquid outlet 132 through the sample liquid inlet 131.

[0092] Furthermore, in some possible embodiments, the extrusion structure is a push rod connected to the movable wall 2b, which drives the movable wall 2b to move through external pressure such as human hand pushing or resistance of linear power components such as telescopic cylinders.

[0093] In other possible embodiments, the extrusion structure includes a screw, one end of which is rotatably connected to the movable arm, and a connecting piece is provided on the fixed wall 2a, on which a threaded hole that cooperates with the screw is provided. Thus, the movable wall 2b is pushed relative to the fixed wall 2a toward the interior of the cavity 200 by the rotation of the screw, thereby reducing the volume of the sampling bottle 2 and squeezing out the sample liquid through the sample liquid flow channel 13.

[0094] In addition, in addition to reducing the internal volume of the sampling bottle 2 to achieve the extraction of the sample liquid through the sample liquid flow channel 13, other methods can also be used to achieve it.

[0095] For example, in some possible embodiments, the sampling bottle 2 is also provided with a pressurizing port (not shown in the figure) located above the liquid level therein, and the pressurizing port is used to be connected to an external air pressure pressurizing device such as a pressurized air pump, so that by pressurizing the sampling bottle 2 and increasing the internal air pressure of the sampling bottle 2, the sample liquid inside the sampling bottle 2 is squeezed out of the sampling bottle 2 through the sample liquid flow channel 13.

[0096] In some possible embodiments, a negative pressure connection port (not shown in the figure) is provided at the sample liquid outlet 132 of the stool sampling rod 1, and the negative pressure connection port is used to connect to an external negative pressure generating device such as a vacuum pump, so that the negative pressure generating device provides negative pressure to the sample liquid flow channel 13 through the negative pressure connection port, thereby extracting the sample liquid in the sampling bottle 2 for subsequent sampling.

[0097] Of course, in other possible embodiments, a syringe or dropper or other extracting device can be used to directly extract the sample liquid in the sampling bottle 2 by inserting it into the stool sample through the sample liquid outlet 132, the sample liquid flow channel 13 and the sample liquid inlet 131.

[0098] See Figure 8 、 Figure 9 In some possible embodiments, the sampling bottle 2 includes a bottle body 21 and a limiting cover 22, wherein the inner side wall of the bottle body 21 and the inner wall of the limiting cover 22 form an inner cavity of the sampling bottle 2, that is, a containing cavity 200 of the sampling bottle 2, and a quantitative limiting hole 201 is opened on the limiting cover 22 for the feces sampling rod 1 to pass through and enter the bottle body 21. The excess feces sample adhered to the outer surface of the rod body of the feces sampling rod 1 is scraped off through the quantitative limiting hole 201, so that the feces sample entering the sampling bottle 2 and mixing with the liquid 3 inside it, such as the protective liquid, is roughly equal.

[0099] In the present application, there is no limitation on the connection method or formation method of the limit cover 22 and the bottle body 21. The limit cover 22 can be integrally formed with the bottle body 21, or the limit cover 22 and the bottle body 21 can be connected by assembly. After the assembly is completed, the limit cover 22 can be detachable or non-detachable from the bottle body 21. For example, a mounting port 211 is provided on the bottle body 21, and the limit cover 22 is installed at the mounting port 211. The limit cover 22 can be connected to the bottle body 21 by, but not limited to, bonding, welding, plugging, snap connection or threaded connection.

[0100] For example, see Figure 8 、 Figure 9 A conical connecting end 221 is provided at one end of the limiting cover, and at least the mounting port 211 of the bottle body 21 is made of an elastically deformable material and / or the connecting end 221 is made of an elastically deformable material, so that the connecting end 221 can be inserted into the mounting port 211 of the bottle body 21 and sealed and fixedly connected to the bottle body 21.

[0101] In another embodiment, a first internal thread (not shown in the figure) may be provided on the inner wall of the mounting port 211, and a first external thread (not shown in the figure) that cooperates with the first internal thread may be provided on the outer wall of the limiting cover 22. The detachable fixation of the limiting cover 22 and the bottle body 21 is achieved by the connection between the first external thread and the first internal thread.

[0102] Of course, when the quantity limiting cover 22 is configured to be inseparably connected to the bottle body 21 , the quantity limiting cover 22 can be installed on the installation opening 211 of the bottle body 21 by means of, but not limited to, bonding or welding.

[0103] In the present application, there is no specific limitation on the connection between the feces sampling rod 1 and the limiting cover 22. The feces sampling rod 1 and the limiting cover 22 can be assembled by, but not limited to, plugging, threading or snapping. For example, see Figure 1 、 Figure 8 、 Figure 9 A second external thread 18 is provided on the outside of the stool sampling rod 1, and a second internal thread 222 that cooperates with the second external thread 18 is provided on the limiting cover 22. The stool sampling rod 1 is fixed to the limiting cover 22 through the cooperation between the second internal thread 222 and the second external thread 18, and then the stool sampling rod 1 is connected to the bottle body 21 through the connection between the limiting cover 22 and the bottle body 21.

[0104] Of course, the second external thread 18 may be provided on the limiting cover 22 , while the second internal thread 222 may be provided in the stool sampling rod 1 , so that the two can be detachably connected.

[0105] See Figure 9The preferred solution is: a accommodating cavity 223 is provided on the side of the limiting cover 22 facing away from the interior of the sampling bottle 2, and the accommodating cavity 223 is used to accommodate the excess feces sample scraped through the quantitative limiting hole 201. The second internal thread 222 is provided on the inner side wall of the accommodating cavity 223, and the second external thread 18 is provided on the outside of the feces sampling rod 1. The second external thread 18 cooperates with the second internal thread 222 to connect the feces sampling rod 1 to the limiting cover 22.

[0106] In order to achieve the best scraping effect, the shape of the quantitative limiting hole 201 is consistent with the cross-sectional shape of the feces sampling rod 1.

[0107] In some possible implementations, the limiting cover 22 may be configured as a rigid member, and the diameter of the quantitative limiting hole 201 may be equal to or slightly larger than the outer diameter of the feces sampling rod 1 .

[0108] In some other possible embodiments, elasticity can be set at least around the quantitative limiting hole 201 on the limiting cover 22, and the aperture of the quantitative limiting hole 201 can be smaller than or equal to the outer diameter of the feces sampling rod 1. In this way, relying on the elastic deformation of at least the quantitative limiting hole 201 on the limiting cover 22, the hole wall of the quantitative limiting hole 201 can fit more closely with the outer surface of the feces sampling rod 1, thereby improving the scraping effect and facilitating sealing, thereby preventing the liquid 3 or odor inside the bottle body 21 from overflowing through the connecting gap between the feces sampling rod 1 and the limiting cover 22.

[0109] In this application, there is no limitation on the shape and size of the sampling bottle 2. The sampling bottle 2 can be cylindrical, truncated cone, polygonal prism, polygonal pyramid, etc., as long as it can meet the requirements of containing the liquid 3. There is no special limitation on the material of the sampling bottle 2, as long as it meets the elastic extrusion requirements and does not react chemically with the protective liquid and fecal sample.

[0110] In some possible embodiments, when a sealing film is provided at the sample liquid inlet 131 of the feces sampling rod 1, a spike structure (not shown in the figure) may be provided in the sampling bottle corresponding to the sealing film. When the feces sampling rod 1 completes the collection of the feces sample and is inserted into the sampling bottle 2, the sealing film is pierced by the spike structure, thereby opening the sample liquid flow channel 13, so that the sample liquid in the sampling bottle 2 can be subsequently removed through the sample liquid flow channel 13.

[0111] The main implementation process and principles of this embodiment are as follows:

[0112] Using the stool sampling device of this embodiment, the second end 12 of the stool sampling rod 1 is inserted into the stool so that the stool sample is accommodated in the sampling groove 121 on the side of the stool sampling rod 1. The stool sampling rod 1 is then taken out of the stool. Next, the stool sample is inserted into the sampling bottle 2. Specifically, the stool sampling rod 1 is passed through the quantitative limiting hole 201 of the limiting cover 22 and enters the bottle body 21. When the stool sampling rod 1 passes through the quantitative limiting hole 201, the excess stool adhering to the outer surface of the stool sampling rod 1 is removed through the quantitative limiting hole 201. The feces sample is scraped off, and the excess feces sample remains in the receiving groove of the limiting cover 22. Subsequently, the feces sample collected on the feces sampling rod 1 is fully mixed with the protective liquid pre-stored in the bottle body 21 by shaking or centrifugation, and then the sampling bottle 2 is squeezed as a whole or the elastically deformed part to reduce the internal volume of the sampling bottle 2. As a result, the protective liquid mixed with the feces sample in the sampling bottle 2, that is, the sample liquid to be tested, is squeezed out through the sample liquid flow channel 13 in the feces sampling rod 1, thereby facilitating the sampling of the sample liquid for testing.

[0113] Of course, the sample liquid to be tested in the sampling bottle 2 can be taken out through the sample liquid flow channel 13 in the feces sampling rod 1 by pouring, pressurizing or negative pressure extraction.

[0114] When using the stool sampling device of this embodiment, there is no need to separate the stool sampling rod 1 from the sampling bottle 2 during the process of collecting the sample liquid in the sampling bottle 2, which can improve the efficiency of sample liquid sampling and reduce the possibility of contact between the tester and the stool sample. It is also beneficial to reduce the emission of the odor of the stool sample and reduce the possibility of causing discomfort to the tester.

[0115] Example 4

[0116] See Figures 11 to 13 The present application discloses another stool sampling and collection device, which includes a sampling bottle 2 and any one of the stool sampling devices in Example 2. The stool sampling and collection device in this embodiment is based on Example 3 and differs from Example 3 only in that:

[0117] In this embodiment, since any one of the stool sampling rods 1 in Example 2 is used, the specific structure of the sampling bottle 2 that is matched with this stool sampling rod 1 is set as follows: a lifting protrusion 202 is also provided in the sampling bottle 2, and the lifting protrusion 202 matches the shape of the sampling groove 121 on the stool sampling rod 1, and the lifting protrusion 202 can be inserted into the sampling groove 121 to push the stool sample, so that the stool sample leaves the sampling groove 121 through the sample inlet hole 15.

[0118] The stool sampling and collection device of this embodiment can, on the one hand, increase the amount of stool samples collected; on the other hand, since the sampling groove 121 can match the lifting protrusion 202 in the sampling bottle 2, after the stool sample is collected, the stool sampling rod 1 is inserted into the sampling bottle 2, and the lifting protrusion 202 can be inserted into the sampling groove 121 to push the stool sample through the sample inlet hole 15, so that the stool sample can be easily separated from the stool sampling rod 1 and fully mixed with the liquid 3 in the sampling bottle 2, thereby reducing the residue of the stool sample in the stool sampling rod 1 and making the stool sample and the liquid 3 in the sampling bottle 2 more fully mixed.

[0119] The main implementation process and principles of this embodiment are as follows:

[0120] Using the stool sampling device of this embodiment, the second end 12 of the stool sampling rod 1 is inserted into the feces, so that the feces sample enters the sampling groove 121 from the end of the feces sampling rod 1, and then the feces sampling rod 1 is removed from the feces. Then, the feces sample is inserted into the sampling bottle 2, and the top material protrusion 202 in the sampling bottle 2 is inserted into the sampling groove 121, and the feces sample is pushed out of the sampling groove 121 through the sample inlet hole 15. Subsequently, the feces sample collected on the feces sampling rod 1 is fully mixed with the protective liquid pre-stored in the bottle body 21 by shaking or centrifugation, and then the sample liquid to be tested in the sampling bottle 2 is taken out through the sample liquid flow channel 13 in the feces sampling rod 1 by squeezing, pouring, pressurizing or negative pressure extraction for subsequent sample liquid testing.

[0121] Example 5

[0122] The present application also discloses a stool sampling and processing device, comprising any one of the stool sampling and collection devices of the above-mentioned embodiment 3 or embodiment 4, and a workbench, wherein the workbench is provided with a receiving groove for placing the sampling bottle 2, and the workbench is also provided with a liquid collecting device, which acts on the stool sampling rod 1 or the sampling bottle 2 to transport the sample liquid in the sampling bottle 2 to the sample liquid outlet 132 through the sample liquid flow channel 13.

[0123] When the sampling bottle 2 is at least partially deformable, the liquid sampling device can adopt a clamping mechanism such as a robotic gripper, and apply external pressure to the deformed part of the sampling bottle 2 through the robotic gripper, so that the deformed part of the sampling bottle 2 is deformed, thereby changing the volume of the sampling bottle 2, and transporting the sample liquid in the sampling bottle 2 to the sample liquid outlet 132 through the sample liquid flow channel 13 for subsequent sample liquid sampling.

[0124] When a sampling bottle 2 with a pressurizing port is used, the liquid sampling device can be set as an air pressure pressurizing device such as a booster air pump, which increases the air pressure in the sampling bottle 2 through the pressurizing port through the pressurizing device, so that the sample liquid in the sampling bottle 2 is transported to the sample liquid outlet 132 through the sample liquid flow channel 13 for subsequent sample liquid sampling.

[0125] When a stool sampling rod 1 provided with a negative pressure connection port is used, the liquid collection device can be set as a negative pressure generating device such as a vacuum pump, and the negative pressure generating device provides negative pressure to the sample liquid flow channel 13 through the negative pressure connection port, so that the sample liquid in the sampling bottle 2 is transported to the sample liquid outlet 132 through the sample liquid flow channel 13 for subsequent sample liquid sampling.

[0126] Of course, the liquid collection device can also be a syringe, dropper or other collection device, which is inserted into the sampling bottle 2 through the sample liquid outlet 132, the sample liquid channel 13 and the sample liquid inlet 131 to directly sample the sample liquid in the sampling bottle 2.

[0127] In summary, the stool sampling rod, stool sampling and collection device, and stool sampling and processing equipment of the present invention improve the convenience of collecting sample liquid to be tested, can reduce the possibility of contact between the tester and the stool sample, and are also beneficial to reduce the emission of stool sample odor, reducing the possibility of causing discomfort to the tester.
