Description

Technical Field

[0001] This invention relates to the field of lactose intolerance detection technology, and in particular to a rapid detection device for fecal samples. Background Technology

[0002] Lactose intolerance testing can be divided into stool testing and urine testing. Stool testing detects the reducing sugar content and uses pH value for judgment. Urine testing detects the galactose content and uses colorimetric analysis based on galactose concentration. Currently, most commercially available lactose intolerance test strips are urine-based. These require more tools, including separate pipettes, purification devices, syringes, and test strips. Urine is easily contaminated. According to the testing principle, the user must first empty their bladder, then drink milk, and collect urine from the second hour for testing. Test kits... It needs to be refrigerated and taken out of the refrigerator half an hour before the test to allow the temperature to return to room temperature. The operation is cumbersome and the accuracy is low. Diet (VC) and drugs can affect the test results. In contrast, stool testing can be done by self-sampling and sending it for testing or by manual testing. Currently, when testing for lactose in stool, the sample is usually diluted first, then the sample is drawn up with a pipette and dripped into the test strip well. The result is then interpreted after incubation at 37°C for 4-10 minutes. During the test, the fecal liquid is open, and the test strip is prone to tipping over and leaking liquid. The incubation temperature is also required, making it inconvenient for operators to conduct the test at home. Summary of the Invention

[0015] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0016] Combined with appendix Figures 1-4 The aforementioned rapid fecal sample detection device includes a detection tube 1. Two limiting mechanisms 2 are respectively installed on the tube body of the detection tube 1. A sampling mechanism 3 is installed on one of the limiting mechanisms 2, and the sampling end of the sampling mechanism 3 is located inside the detection tube 1. An impurity filtering mechanism 5 is installed inside the detection tube 1, and the impurity filtering mechanism 5 is located below the sampling end of the sampling mechanism 3.

[0017] The detection tube 1 is equipped with an anti-seepage layer 4, which is located between the sampling end of the sampling mechanism 3 and the impurity filtration mechanism 5 to further prevent reagent leakage.

[0018] The detection tube 1 includes a tube body 101, an arc-shaped sliding plate 102, and a colorimetric tube 103. There are two tube bodies 101. The bottom end of each tube body 101 is fixedly connected to the arc-shaped sliding plate 102, and the arc-shaped sliding plate 102 is slidably connected to the colorimetric tube 103. Limiting mechanisms 2 are respectively installed between the top end and the bottom end of each tube body 101 and the colorimetric tube 103. A sealing paper is installed inside the colorimetric tube 103, and the colorimetric tube 103 contains the detection liquid. The detection liquid is sealed and protected by the sealing paper.

[0019] The bottom of the colorimetric tube 103 is flat, making it convenient for users to place the test tube 1 vertically.

[0020] The limiting mechanism 2 includes a safety ring 201 and a connecting belt 202. There are two sets of safety rings 201, with two safety rings in each set. The two sets of safety rings 201 are located at the top end of the tube body 101 and the bottom end of the tube body 101 between the tube body 101 and the color developing tube 103, respectively. The connecting belt 202 is fixedly connected between the two safety rings 201.

[0021] A cover paper is attached to the inside of the safety ring 201 at the top. Remove the cover paper from the safety ring 201 at the top and place it over the sample to avoid discomfort caused by the user directly facing the sample.

[0022] The sampling mechanism 3 includes a pull plate 301, a sampling rod 302, and a seepage-proof plate 303. The pull plate 301 is located on and in contact with the safety ring 201 at the top, and the sampling rod 302 is fixedly connected to the pull plate 301. The seepage-proof plate 303 is fixedly connected to the sampling rod 302, and the seepage-proof plate 303 is in contact with the inner wall of the pipe body 101. The bottom end of the sampling rod 302 is provided with spiral patterns to facilitate the adhesion of samples.

[0023] The anti-spillage paper is adhered to the impermeable plate 303, and the anti-spillage paper has the same style as the covering paper. Remove the anti-spillage paper from the impermeable plate 303 and wrap it around the top of the detection tube 1 so that the opening of the anti-spillage paper is aligned with the opening of the detection tube 1, so as to prevent the sample from dripping onto the outer wall or other positions of the detection tube 1 when the sampling rod 302 is inserted.

[0024] The impurity filtration mechanism 5 includes an activated carbon filter layer 501, a funnel 502, and a filter paper layer 503. The activated carbon filter layer 501, funnel 502, and filter paper layer 503 are all located inside the tube body 101 and are fixedly connected. The filter paper layer 503 is located between the activated carbon filter layer 501 and the funnel 502. The activated carbon filter layer 501 is located below the anti-seepage layer 4. The activated carbon filter layer 501 adsorbs odors, reduces sample odors, clarifies the sample solution, and reduces the impact on the final color comparison observation.

[0025] In the aforementioned rapid fecal sample testing device, the user removes the upper safety ring 201 and the covering paper inside the top safety ring 201. The covering paper is then placed over the sample to prevent discomfort caused by direct contact with the sample. The sampling rod 302 is removed from the detection tube 1, and the standard solution is poured into the detection tube 1. The anti-spillage paper on the anti-seepage plate 303 is removed and wrapped around the top of the detection tube 1, ensuring the opening of the anti-spillage paper aligns with the opening of the detection tube 1. This prevents sample from dripping onto the outer wall or other parts of the detection tube 1 when the sampling rod 302 is inserted, thus avoiding interference with the user's handling. One end of the sampling rod 302 is passed through the opening in the covering paper to collect the sample. The sample-covered sampling rod 302 is then returned to the detection tube 1. When the sampling rod 302 is in place, the anti-spillage paper is pushed into the detection tube 1 through the anti-seepage plate 303 to avoid the user having to collect it separately. The staff resets the upper safety ring 201 and removes the lower safety ring 201. Pressing the pull plate 301, the bottom end of the funnel 502 passes through the sealing paper in the colorimetric tube 103. The sampling rod 302 is pushed by the pull plate 301, so that the end of the sampling rod 302 dipped in the sample passes through the anti-seepage layer 4. The sample and standard solution enter the impurity filtration mechanism 5 together. The impurities are filtered through the activated carbon filter layer 501 and the filter paper layer 503, making the standard solution dipped in the sample clear, which is convenient for the user to observe. The standard solution mixed with the sample is put into the colorimetric tube 103 through the funnel 502, where it reacts with the liquid in the colorimetric tube 103 for the user to observe.
