Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a portable and pollution-free integrated fecal sampling and detection device. Background Art

[0002] Fecal sample detection is an important non-invasive means for screening digestive tract diseases, especially colorectal cancer. Its core is to detect hemoglobin and transferrin in feces through immunochromatography. This method uses antibodies labeled with latex microspheres, colloidal gold or quantum dots to bind to target biomarkers, forming visible color bands on the test kit, and judging whether there is abnormal bleeding through colorimetry. The combined detection of hemoglobin / transferrin has become a standardized program for early screening of colorectal cancer due to its high sensitivity and relatively simple operation. In recent years, with the growth of the demand for home detection, this technology has gradually extended from medical institutions to home scenarios, aiming to improve the screening coverage rate and user compliance.

[0003] The current detection process requires the examinee to collect a fecal sample using a sampling stick, transfer it to a specimen processing tube containing diluent, mix it evenly, open the cap and drop it onto the reagent card and interpret the result. However, this process has obvious defects: on the one hand, non-professional users are prone to deviations in test results due to improper control of the sampling amount (such as excessive sampling), and leakage is likely to occur during the mixing and opening processes; on the other hand, unpleasant odors are easily emitted during opening and dropping, affecting the comfort of the detection environment; in addition, the sample needs to be mixed with the stabilizing solution and sent for inspection in a timely manner, and some users may give up the detection due to cumbersome operations or time delays, resulting in a decrease in the detection rate; finally, most existing integrated detection devices are for single items, and repeated sampling is required for multi-index combined detection, which not only increases the operation burden but also may pose a risk of cross-contamination.

[0004] The existing technologies are difficult to meet the core requirements of "integration, multi-project, and convenience" in the home scenario. Although there are already home devices integrating collection and detection functions on the market, their functions are fragmented and lack flexibility. For example, sample collection, pretreatment, and detection need to be carried out step by step, and users cannot select the combination of detection items as needed, resulting in waste of resources. At the same time, multiple opening operations not only exacerbate the risk of odor dissipation and sample contamination, but also non-standard sampling may reduce the detection sensitivity.

[0005] Therefore, it is necessary to propose a portable and pollution-free integrated fecal sampling and detection device to solve the above problems. Summary of the Invention

A second buckle is provided at one end of the inner side of the rotating ring. A second horizontal slide rail corresponding to the second buckle is provided on one side of the upper end of the test strip holder. A second vertical slide rail is provided at the upper end of one end of the second horizontal slide rail.

Detailed implementation manners

[0036] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various interchangeable structural ways and implementation manners. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0037] According to an embodiment of the present invention, it is combined with Figures 1-12 shown.

[0038] As Figures 1-6 shown, a portable and pollution-free integrated device for fecal sampling and detection includes a sampling housing 2. One end of the sampling housing 2 is a square structure 8, and the other end is a cylindrical structure 5 and is connected to the square structure 8. Openings are provided at the tops of both the cylindrical structure 5 and the square structure 8. A sampling rod 1 for sampling feces is vertically and movably inserted into the upper end of the square structure 8. The lower end of the sampling rod 1 is a conical structure, and the diameter of the upper end is larger than that of the lower end. A threaded structure 6 is provided at the lower end of the sampling rod 1, and the threaded structure 6 is used for quantitatively sampling feces. A first through hole 7 is provided in the middle of the inner side of the square structure 8. A groove 17 is provided on the outer side of the middle part of the sampling rod 1, and a sealing ring 18 is installed in the groove 17. The sealing ring 18 is used for abutted cooperation with the inner wall of the first through hole 7. The upper end of the first through hole 7 is conical to facilitate the entry of the sealing ring 18, and the lower end is cylindrical to facilitate pressing down the sampling rod 1 to quantitatively push the solution into the receiving groove 11 through the sealing ring 18. A test strip holder housing 3 is ultrasonically welded to the upper end of the cylindrical structure 5. A test strip holder 4 is movably arranged inside the test strip holder housing 3. The upper end of the test strip holder 4 is a cylindrical structure, and the diameter is adapted to the inner diameter of the test strip holder housing 3. The lower end of the test strip holder 4 is a semi-cylindrical structure. A test strip groove 10 for fixing the test strip is provided on the limiting side of the test strip holder 4. The test strip groove 10 is one or two, so that either a single-slot single-test holder or a double-test holder can be selected. The structure is simple and the replacement is convenient. A spike 16 is provided at the bottom of the test strip holder 4, and an aluminum foil 30 corresponding to the spike 16 is heat-sealed at the upper end of the inner side. Specifically, a partition 9 is provided at one end of the inner side of the cylindrical structure 5 away from the square structure 8. A receiving groove 11 is formed between the side of the partition 9 close to the square structure 8 and the inner wall of the cylindrical structure 5. The aluminum foil 30 is arranged between the partition 9 and the inner wall of the cylindrical structure 5. The partition 9 can isolate the solution in the receiving groove 11. In order to facilitate observing the test strip, an observation window 14 corresponding to the test strip groove 10 and being transparent is provided in the middle of the side of the test strip holder housing 3 facing away from the square structure 8.

[0039] As Figure 7 shown, in order to balance the air pressure by allowing air to flow inside and outside after pressing down the test strip holder 4, a second through hole 19 is provided at one end of the upper end of the test strip holder 4 away from the semi-cylindrical structure.

[0040] As Figure 3 、 Figure 5As shown in the figure, in order to increase the stability of the test strip holder 4, an arc-shaped positioning protrusion 31 is provided on the inner wall of the receiving groove 11, and an arc-shaped positioning depression 20 is provided on the lower side edge of the test strip holder 4. The arc-shaped positioning depression 20 corresponds to and fits with the arc-shaped positioning protrusion 31. When the test strip holder 4 is moved down to the lowest point, the arc-shaped positioning protrusion 31 is inserted into the arc-shaped positioning depression 20, which increases the stability of the test strip holder 4 and realizes the positioning effect.

[0041] As Figure 3 , Figures 5-6 shown, in order to ensure that the test strip holder 4 can be vertically displaced and ensure that the test strip slot 10 corresponds to the observation window 14 and the arc-shaped positioning protrusion 31 corresponds to the arc-shaped positioning depression 20, the test strip holder 4 is connected to the test strip holder housing 3 through a guiding structure. The guiding structure includes a first vertical slide rail 13 vertically arranged on the inner cavity side wall of the test strip holder housing 3, and a first buckle 12 for movably guiding and cooperating with the first vertical slide rail 13 is provided on the upper side wall of the test strip holder 4.

[0042] In order to prevent the test strip holder 4 from being accidentally touched and moving down to pierce the aluminum foil 30, a limiting component for restricting the downward movement of the test strip holder 4 is provided at the upper end of the test strip holder housing 3.

[0043] As Figure 7 shown, as the first embodiment of the limiting component, the limiting component is a first horizontal slide rail 21 provided on one side of the upper end of the first vertical slide rail 13. The first horizontal slide rail 21 communicates with the first vertical slide rail 13. Initially, the first buckle 12 is located inside the first horizontal slide rail 21, so as to longitudinally limit the test strip holder 4. Anti-slip strips can be provided on the inner cavity opposite side walls of the first horizontal slide rail 21 and the first vertical slide rail 13, and the first buckle 12 is in close contact with the anti-slip strips, so that it will not easily move in the first horizontal slide rail 21 and the first vertical slide rail 13.

[0044] As Figures 8-9 shown, as the second embodiment of the limiting component, the limiting component includes a flange 22 provided on the upper end edge of the test strip holder 4 and protruding from the circumferential side wall of the test strip holder 4. An arc-shaped limiting snap ring 23 is sleeved outside the upper end of the test strip holder 4. The limiting snap ring 23 is located between the top of the test strip holder housing 3 and the bottom of the flange 22, so as to longitudinally limit the test strip holder 4.

[0045] As Figures 10-12As shown in the figure, it is the third embodiment of the limiting component. The limiting component includes a rotating ring 24 rotatably arranged on the top of the test strip holder housing 3. Specifically, an annular guide rail 28 is provided on the top of the test strip holder housing 3, and an arc-shaped chute 29 adapted to the annular guide rail 28 is provided at the bottom of the rotating ring 24. The rotating ring 24 is movably connected to the outside of the annular guide rail 28 through the arc-shaped chute 29, and the two are inseparable. A second buckle 27 is provided at one end of the inner side of the rotating ring 24, and a second horizontal slide rail 26 corresponding to the second buckle 27 is provided on one side of the upper end of the test strip holder 4. A second vertical slide rail 25 is provided at the upper end of one end of the second horizontal slide rail 26. Initially, the second buckle 27 is located inside the second horizontal slide rail 26, so as to longitudinally limit the test strip holder 4. Anti-slip strips can be provided on the opposite side walls of the inner cavities of the second vertical slide rail 25 and the second horizontal slide rail 26. The second buckle 27 is in close contact with the anti-slip strips, so that it will not easily move in the second vertical slide rail 25 and the second horizontal slide rail 26.

[0046] As Figures 1-2 shown, in order to facilitate increasing the stability of the square structure 8 and the test strip holder housing 3, a square ring 15 is provided on one side of the test strip holder housing 3. The square ring 15 is used to sleeved with the square structure 8, so as to be connected as a whole.

[0047] Use the sampling rod 1 to take fecal samples. The threaded structure 6 at the free end of the sampling rod 1 can quantitatively pick up feces. The sampling rod 1 is inserted into the square structure 8 at one end of the sampling housing 2. The fecal diluent is pre-filled in the square structure 8. The feces on the threaded structure 6 are resuspended in the fecal diluent to form a sample mixture. The sealing ring 18 abuts against the inner wall of the first through hole 7 to achieve sealing. The sampling and the mixing process of the sample and the diluent will not be misoperated, resulting in a detection failure. After sampling, release the limiting effect of the limiting component and press down the test strip holder 4. The spike 16 at the lower end of the test strip holder 4 pierces the aluminum foil 30 and enters the receiving groove 11. The test strip contacts the sample mixture in the receiving groove 11. The mixed solution starts to be detected through the glass fiber siphon effect of the test strip. Wait until a color band appears, and then the color card can be compared to determine the result.

[0048] Compared with the prior art structure, the present invention has the following advantages:

[0049] The production efficiency of the product is improved, the operation process is reduced, the product quality is improved, and the mechanical structure connection ensures sealing, reducing or eliminating the risk of liquid leakage; in the previous products, glue was coated, which affected the buffer solution and the detection functionality of the test strip, reducing the sensitivity of the product or causing false positives.

[0050] It improves the convenience of use. Just unplug the sampling rod 1, take a sample, plug the sampling rod 1 back and shake it, release the limit and press the test strip holder 4, and read the color band that appears within the specified time to complete the test. In the past, the product required unplugging the lid, taking a sample, plugging the lid back and shaking it, tearing off the safety sticker, pressing the lid, pulling out the lid to the original position, squeezing the tube body hard, and waiting for the color band to appear. The time for the color band to appear was uncontrollable, and the force of different operators squeezing the tube body was uncontrollable, resulting in large differences in the reading results.

[0051] The sample liquid required for detection can be quantified. Each product sealing ring 18 acts as a piston to push the same volume of transferred liquid, and is not affected by different operators. In the past, different people squeezed the tube body, and due to different squeezing forces, the amount of transferred liquid was uncontrollable.

[0052] Comparative Example 1: Comparison with a commercial Helicobacter pylori detection kit

[0053] The present invention and a commercial Helicobacter pylori detection kit (commercial test card) were used to detect 20 fecal samples respectively. The commercial Helicobacter pylori detection kit was sampled, loaded, and the test sample was read according to the instructions. The obtained data are statistically as follows:

[0054]

[0055] In the table, "+" represents a positive detection and "-" represents a negative detection. It can be seen that the integrated device of the present invention can accurately and simply detect samples without a complex sample processing process. Since the detection process is carried out in a closed environment, there is no peculiar smell, which is friendly to non-professionals (such as household users or non-clinical laboratory doctors). For professionals, it can also reduce the workload and quickly process a large number of samples.

[0056] Comparative Example 2: Comparison with a hemoglobin / transferrin combined detection kit

[0057] The present invention and a commercial occult blood immune dipstick hemoglobin / transferrin combined detection kit (commercial test card) were used to detect 20 fecal samples respectively. The commercial occult blood immune dipstick was sampled, loaded, and the test sample was read according to the instructions. The obtained data are statistically as follows:

[0058] Hemoglobin test results:

[0059]

[0060] Transferrin test results:

[0061]

[0062] In the table, "+" represents a positive test result and "-" represents a negative test result. It can be seen that the present invention can simultaneously detect two items on the same biological sample, without the need for a complex sample processing procedure, which is more convenient for non-professionals to use, such as household users or non-laboratory doctors. When used by professionals, the workload can be reduced and a large number of samples can be detected quickly.

[0063] The present invention overcomes the deficiencies of the prior art, integrating functions such as quantitative collection, resuspension, and immunochromatographic strip detection of fecal samples. It is convenient to carry and operate. After sampling, it is not necessary to directly observe the feces for detection, and there will be no liquid leakage during storage, transportation, and detection. General adults can perform self-testing for fecal occult blood. The present invention combines the sampling rod 1 and the test strip in one device. The liquid storage cavity and the test strip cavity are relatively airtight and independent. Patients can perform home testing. According to the usage instructions, they can complete sampling, detection, and interpretation at home. The operation is convenient and fast, improving the freshness of sample preservation and the accuracy of test results.

[0064] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
