Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a feces collection device. Background Art

[0002] Fecal testing has significant clinical significance for the function of organs such as the stomach, intestines, liver, gallbladder, and pancreas, as well as digestive tract diseases. Stool testing can provide clinical evidence for conditions such as gastrointestinal absorption disorders, acute and chronic intestinal inflammation, parasitic diseases, and gastrointestinal bleeding. During stool sample testing, the sample must first be quantitatively collected and mixed with a diluent before being loaded for testing.

[0003] In the stool sampling reaction device in the prior art, the reaction liquid after the sampling reaction cannot be directly dripped onto the detection plate. It is necessary to open the bottle cap and use a pipette or the like to transfer the reaction liquid to the detection plate before testing. At the same time, there is also the problem of being unable to quantitatively sample the sampling amount of the stool sample or the accuracy of the sampling amount of the stool sample is insufficient. Excessive or insufficient sampling of stool samples can easily lead to excessively high or low sample concentrations in the reaction liquid, further resulting in the inability to determine the sample concentration in the reaction liquid. The different sample concentrations in the reaction liquid can affect the accuracy of the test results, which can lead to misjudgment of the test results. In addition, during sampling, excessive stool samples can easily overflow due to insufficient retention space in the stool sampling reaction device. Utility Model Content

[0004] The utility model aims to overcome the defects of the feces sampling reaction device in the prior art, such as the inability to quantitatively sample feces samples, the inaccurate sampling amount, and the easy overflow of excessive feces samples during sampling, and provides a feces collection device to overcome the above defects.

[0005] In order to achieve the above-mentioned purpose of the invention, the present invention is implemented through the following technical solutions:

[0006] A feces collecting device, comprising:

[0007] A sampling assembly, comprising a sampling rod, wherein the upper end of the sampling rod is covered with a middle cover, the top of the middle cover is provided with a dripping port, the outside of the dripping port is covered with an upper cover, the interior of the sampling rod is provided with a sampling rod through groove for liquid circulation, the top and bottom of the sampling rod through groove are both provided with sampling rod through holes connected to the sampling rod through groove, the sampling rod through hole near the top of the sampling rod through groove is connected to the dripping port, and the lower portion of the sampling rod is provided with a sampling thread;

[0008] The sampling assembly includes a bottle body and a sealing plug detachably connected to the bottle body. The outer wall of the sealing plug is provided with a sealing portion that seals with the bottle body. The interior of the sealing plug is provided with a cache cavity for accommodating excess fecal samples. The bottom of the cache cavity is provided with a sealing plug through hole for inserting a sampling rod.

[0009] The utility model includes a sampling assembly. The sampling assembly includes a sampling rod, the upper end of the sampling rod is covered with a middle cover, the top of the middle cover is provided with a dripping port, and the outside of the dripping port is covered with an upper cover. The interior of the sampling rod is provided with a sampling rod through groove for liquid circulation, and the top and bottom of the sampling rod through groove are both provided with sampling rod through holes connected to the sampling rod through groove. The sampling rod through hole near the top of the sampling rod through groove is connected to the dripping port, and the lower part of the sampling rod is provided with a sampling thread. The utility model also includes a sampling assembly. The sampling assembly includes a bottle body and a sealing plug detachably connected to the bottle body. The outer side wall of the sealing plug is provided with a sealing portion that seals with the bottle body, the interior of the sealing plug is provided with a cache cavity for accommodating excess fecal samples, and the bottom of the cache cavity is provided with a sealing plug through hole for inserting the sampling rod.

[0010] The present invention is designed to have a sampling rod with a sampling thread at the bottom that is combined with a sealing plug through-hole structure, so that when the sampling rod is inserted into the sealing plug through-hole, the excess fecal sample on the sampling rod is scratched and temporarily retained, which helps to achieve quantitative sampling of the fecal sample and improves the accuracy of the fecal sampling amount. In addition, the buffer cavity designed in the present invention forms a sufficiently large retention space between the top of the sampling rod and the sampling rod to accommodate excess fecal sample, effectively preventing excess fecal sample from overflowing. In addition, the present invention provides a buffer solution in the bottle body to control the quantitative dissolution of the fecal sample on the sampling thread structure at the bottom of the sampling rod in the buffer solution, which helps to ensure that a quantitative amount of fecal sample is dissolved in the buffer solution, thereby ensuring the concentration range of the fecal sample in the buffer solution, further improving the accuracy of the test results, and effectively avoiding the occurrence of misjudgment of the test results. In addition, the utility model sets a buffer solution in the bottle body and controls the fecal sample on the sampling thread structure to be quantitatively dissolved in the buffer solution to form a test sample reaction liquid. When the bottle body is squeezed, the test sample reaction liquid flows out through the sampling rod groove, the sampling rod through hole, and the dripping port, thereby facilitating direct sampling without transferring the test sample reaction liquid, which is simple, fast and efficient.

[0011] Preferably, a middle cover sealing portion and an internal thread are provided inside the middle cover, and a sampling rod sealing ring is further provided at the upper end of the sampling rod, and the middle cover sealing portion is snap-fitted with the sampling rod sealing ring.

[0012] By setting a sampling rod sealing ring and cooperating with the middle cover sealing part, it is helpful to achieve a seal between the top of the sampling rod and the middle cover, thereby sealing the retention space, further effectively isolating the buffer solution in the bottle body from contact with the excess fecal sample temporarily stored in the retention space.

[0013] Preferably, the bottle body comprises an outer shell and a bottle mouth located at the top end of the outer shell, and the outer side of the bottle mouth is provided with an external thread that matches the internal thread provided in the middle cover.

[0014] The cooperation of external and internal threads helps to form a tight seal while facilitating connection and disassembly.

[0015] Preferably, a receiving cavity for receiving a buffer solution is provided inside the bottle body, an undercut portion is provided on the inner side wall of the receiving cavity at a position corresponding to the sealing portion, and the undercut portion is snap-connected to the sealing portion.

[0016] The design of the snap-fit ​​connection between the undercut portion and the sealing portion helps to improve the stability of the overall structure, effectively preventing the sealing plug from being pulled out of the bottle body and falling off when the sampling rod is removed, and further ensuring the overall sealing.

[0017] Preferably, the lower end of the sampling rod passes through the sealing plug through hole and extends downward into the accommodating cavity, and the sampling rod through hole near the bottom of the sampling rod through groove is communicated with the accommodating cavity.

[0018] The above arrangement facilitates the direct insertion of the sampling rod into the receiving chamber, and controls the quantitative dissolution of the fecal sample on the sampling thread structure in the buffer solution in the receiving chamber to form a test sample reaction liquid. When the bottle body is squeezed, the test sample reaction liquid enters the sampling rod through hole near the bottom of the sampling rod through groove from the receiving chamber, flows along the sampling rod through groove into the sampling rod through hole near the top of the sampling rod through groove, and then flows out from the drip port connected thereto, thereby directly sampling from the buffer solution in the receiving chamber without the need for additional transfer steps, reducing the risk of sample contamination and loss, facilitating subsequent sampling, and being simple and efficient to operate.

[0019] Preferably, the diameter of the lower portion of the sampling rod at the sampling thread is equal to the diameter of the through hole of the sealing plug.

[0020] The above arrangement creates a tight fit between the sampling rod and the through-hole of the sealing plug, effectively preventing the buffer solution in the bottle from leaking through the gap into the buffer chamber and coming into contact with excess fecal sample during the sampling process. This also facilitates smooth insertion of the sampling rod into the through-hole of the sealing plug, ensuring that the sampling rod accurately scrapes away any excess fecal sample temporarily retained on the sampling rod during insertion, facilitating quantitative sampling of the fecal sample and improving the accuracy of fecal sampling.

[0021] Preferably, the sealing plug is located inside the bottle body.

[0022] When the sealing plug is located inside the bottle, it creates a double seal with the bottle and sampling rod, effectively preventing leakage of the buffer solution and enhancing the sealing performance. Furthermore, the internal sealing plug design effectively prevents external air, moisture, and impurities from entering the bottle, thereby maintaining the purity and stability of the buffer solution or other stored substances.

[0023] Preferably, the sealing plug is arranged at the bottle mouth at the top end of the bottle body.

[0024] When the sealing plug is installed at the top of the bottle, it can effectively prevent the buffer solution in the bottle from leaking, and can also effectively block external impurities to ensure the sealing performance. At the same time, it is easy to install and remove, which is convenient for subsequent maintenance and inspection.

[0025] Therefore, the utility model has the following beneficial effects:

[0026] (1) The present invention is characterized by a sampling rod with a sampling thread on the lower portion and a sealing plug through-hole structure, so that when the sampling rod is inserted into the sealing plug through-hole, the excess feces sample on the sampling rod is scratched and temporarily retained, which helps to achieve quantitative sampling of the feces sample and improves the accuracy of the feces sampling amount;

[0027] (2) The buffer chamber and the top of the sampling rod of the present invention form a sufficiently large retention space for accommodating excess fecal samples, thereby effectively preventing excess fecal samples from overflowing;

[0028] (3) The present invention provides a buffer solution in the bottle body to control the quantitative dissolution of the fecal sample on the sampling thread structure at the lower part of the sampling rod in the buffer solution, which helps to ensure that a quantitative amount of fecal sample is dissolved in the buffer solution, thereby ensuring the concentration range of the fecal sample in the buffer solution, further improving the accuracy of the test results, and effectively avoiding the occurrence of misjudgment of the test results;

[0029] (4) The utility model provides a buffer solution in the bottle body and controls the fecal sample on the sampling thread structure to be quantitatively dissolved in the buffer solution to form a sample reaction liquid to be tested. When the bottle body is squeezed, the sample reaction liquid to be tested flows out through the sampling rod groove, the sampling rod through hole, and the dripping port, thereby facilitating direct sampling without transferring the sample reaction liquid to be tested, which is simple, fast, and efficient.

Based on these descriptions, a person skilled in the art will be able to implement the present invention. Furthermore, the embodiments of the present invention described below generally represent only a portion of the present invention, rather than all of the embodiments. Therefore, all other embodiments derived by a person skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0052] Example 1

[0053] like Figure 1-10 As shown, the utility model includes a sampling assembly 1. The sampling assembly 1 includes a sampling rod 2, the upper end of the sampling rod 2 is covered with a middle cover 3, the top of the middle cover 3 is provided with a dripping port 4, and the outside of the dripping port 4 is covered with an upper cover 5. The interior of the sampling rod 2 is provided with a sampling rod through groove 6 for liquid circulation, and the top and bottom of the sampling rod through groove 6 are both provided with sampling rod through holes 7 connected to the sampling rod through groove 6. The sampling rod through hole 7 near the top of the sampling rod through groove 6 is connected to the dripping port 4, and the lower part of the sampling rod 2 is provided with a sampling thread 8. The utility model also includes a sampling assembly 9. The sampling assembly 9 includes a bottle body 10 and a sealing plug 11 detachably connected to the bottle body 10. The outer wall of the sealing plug 11 is provided with a sealing portion 12 that seals with the bottle body 10. The interior of the sealing plug 11 is provided with a buffer cavity 13 for accommodating excess fecal samples. The bottom of the buffer cavity 13 is provided with a sealing plug through hole 14 for inserting the sampling rod 2.

[0054] The present invention is designed to have a sampling rod 2 with a sampling thread 8 at the bottom, which is matched with the sealing plug through hole 14 structure. When the sampling rod 2 is inserted into the sealing plug through hole 14, the excess fecal sample on the sampling rod 2 is scratched and temporarily retained, which helps to achieve quantitative sampling of the fecal sample and improves the accuracy of the fecal sampling amount. In addition, the buffer cavity 13 designed in the present invention forms a sufficiently large retention space between the top of the sampling rod 2 and is used to accommodate excess fecal samples, effectively preventing excess fecal samples from overflowing. In addition, the present invention provides a buffer solution in the bottle body 10 to control the quantitative dissolution of the fecal sample on the sampling thread 8 structure at the bottom of the sampling rod 2 in the buffer solution, which helps to ensure that a quantitative amount of fecal sample is dissolved in the buffer solution, thereby ensuring the concentration range of the fecal sample in the buffer solution, further improving the accuracy of the test results, and effectively avoiding the occurrence of misjudgment of the test results. In addition, the utility model sets a buffer solution in the bottle body 10 and controls the fecal sample on the sampling thread 8 structure to be quantitatively dissolved in the buffer solution to form a sample reaction liquid to be tested. When the bottle body 10 is squeezed, the sample reaction liquid to be tested flows out through the sampling rod groove 6, the sampling rod through hole 7, and the dripping port 4, thereby facilitating direct sampling without transferring the sample reaction liquid to be tested, which is simple, fast and efficient.

[0055] As an embodiment, a middle cover sealing portion 15 and an internal thread 16 are provided inside the middle cover 3 , and a sampling rod sealing ring 17 is further provided at the upper end of the sampling rod 2 . The middle cover sealing portion 15 and the sampling rod sealing ring 17 are snap-fitted together.

[0056] By providing the sampling rod sealing ring 17 and cooperating with the middle cover sealing portion 15, it is helpful to achieve a seal between the top of the sampling rod 2 and the middle cover 3, thereby sealing the retention space, further effectively isolating the buffer solution in the bottle body 10 from the excessive fecal sample temporarily stored in the retention space.

[0057] As an embodiment, the bottle body 10 includes an outer shell 18 and a bottle mouth 19 located at the top of the outer shell 18 . The outer side of the bottle mouth 19 is provided with an external thread 20 that matches the internal thread 16 provided in the middle cover 3 .

[0058] The cooperation between the external thread 20 and the internal thread 16 helps to form a tight seal while facilitating connection and disassembly.

[0059] As an embodiment, a receiving cavity 21 for receiving a buffer solution is provided inside the bottle body 10 , and an undercut portion 22 is provided on the inner wall of the receiving cavity 21 at a position corresponding to the sealing portion 12 , and the undercut portion 22 is snap-connected to the sealing portion 12 .

[0060] The design of the undercut portion 22 being snap-connected with the sealing portion 12 helps to improve the overall structural stability, effectively preventing the sealing plug 11 from being pulled out of the bottle body 10 and falling off when the sampling rod 2 is removed, and further ensuring the overall sealing.

[0061] As an embodiment, the lower end of the sampling rod 2 passes through the sealing plug through hole 14 and extends downward into the accommodating cavity 21 , and the sampling rod through hole 7 near the bottom of the sampling rod through groove 6 is connected to the accommodating cavity 21 .

[0062] The above arrangement facilitates the direct insertion of the sampling rod 2 into the accommodating chamber 21, and controls the quantitative dissolution of the fecal sample on the sampling thread 8 structure in the buffer solution in the accommodating chamber 21 to form a sample reaction liquid to be tested. When the bottle body 10 is squeezed, the sample reaction liquid to be tested enters the sampling rod through hole 7 near the bottom of the sampling rod through groove 6 from the accommodating chamber 21, flows along the sampling rod through groove 6 into the sampling rod through hole 7 near the top of the sampling rod through groove 6, and then flows out from the drip port 4 connected thereto, thereby directly sampling from the buffer solution in the accommodating chamber 21 without the need for additional transfer steps, reducing the risk of sample contamination and loss, facilitating subsequent sampling, and being simple and efficient to operate.

[0063] As an embodiment, the diameter of the lower portion of the sampling rod 2 located at the sampling thread 8 is equal to the diameter of the sealing plug through hole 14 .

[0064] The above arrangement creates a tight fit between the sampling rod 2 and the sealing plug through-hole 14, effectively preventing the buffer solution within the bottle body 10 from leaking through the gap into the buffer chamber 13 and coming into contact with excess stool sample during the sampling process. This also facilitates smooth insertion of the sampling rod 2 into the sealing plug through-hole 14, ensuring that the sampling rod 2 accurately scrapes away any excess stool sample temporarily retained on the sampling rod 2 during insertion, thereby facilitating quantitative sampling of the stool sample and improving the accuracy of stool sampling.

[0065] As an embodiment, the sealing plug 11 is located inside the bottle body 10 .

[0066] When the sealing plug 11 is located inside the bottle body 10, it forms a double seal with the bottle body 10 and the sampling rod 2, effectively preventing leakage of the buffer solution and enhancing the sealing performance. Furthermore, the internal sealing plug 11 design effectively prevents external air, moisture, and impurities from entering the bottle body 10, thereby maintaining the purity and stability of the buffer solution or other stored substances.

[0067] Example 2

[0068] like Figure 11-20 As shown, the difference between this embodiment and embodiment 1 is:

[0069] The sealing plug 11 is arranged at the bottle mouth 19 at the top end of the bottle body 10. Other features are the same as those in Example 1.

[0070] When the sealing plug 11 is arranged at the bottle mouth 19 at the top of the bottle body 10, it can effectively prevent the buffer solution in the bottle body 10 from leaking, and can also effectively block external impurities to ensure the sealing performance. At the same time, it is easy to install and disassemble, and convenient for later maintenance and inspection.
