Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an integrated feces sampling and detection device. Background Art

[0002] Stool sampling plays a vital role in the detection of digestive tract problems and the screening of digestive system tumors. Traditional detection methods, such as immunochromatography, usually require patients to collect stool samples according to doctor's orders, and medical personnel use sampling tubes to take samples. The sample is then mixed with a stabilizing solution and dripped into the test kit for testing. This method uses antibodies labeled with latex microspheres, quantum dots or colloidal gold to bind to hemoglobin in the stool to form a visible color band, thereby determining whether there is gastrointestinal bleeding. The interpretation of the test results usually relies on the comparison of the color depth of the color band with the standard color card to distinguish between negative or positive results. A positive result indicates that further medical examination may be required.

[0003] However, the traditional stool sampling and testing method faces some challenges in actual operation. First, the sample is prone to leakage when the lid is opened after mixing, and odor may be generated during the process of adding samples and interpreting the results, causing discomfort to the testers. Secondly, since sampling is usually done by non-professionals, the control of the sampling volume is often not precise enough, and excessive sampling may affect the accuracy of the experimental test results. In addition, there are requirements for sample preservation and transportation during stool collection and inspection. Some people may ignore or fail to submit for inspection in time for various reasons, resulting in a low stool sampling inspection rate.

[0004] In order to improve the convenience and acceptance of screening, more convenient detection methods such as immune test strips have emerged in recent years. This method is easy to operate, allowing community residents to test and determine the results at home, thereby improving the efficiency and coverage of screening. However, the devices that integrate collection and detection currently available on the market still have limitations such as complex operation and single detection items. When conducting multi-item testing, the detection of different items often requires re-collection of fecal samples, which increases the complexity of the operation.

[0005] Therefore, with the development of society and the increasing demand for home testing, it is particularly important to develop a device that can collect and test stool samples and allow the test subject to choose the type and number of test items according to the test needs. This device will help improve the convenience, accuracy and coverage of stool sampling and testing, and provide strong support for the early detection and prevention of digestive tract problems.

When installed in place, the two triangular baffles 26 fit each other, further increasing the stability.

[0048] Working principle: when in use, remove the sampling stick cap 15 to take out the sampling stick 1, and use the sampling stick 1 to take feces samples. Specifically, the free end of the sampling stick 1, that is, the threaded structure 9 at the lower end, can quantitatively stick feces, and then the lower end of the sampling stick 1 is inserted into the sampling shell 4, and the sampling stick cap 15 is sleeved on the outside of the sampling shell 4. The lower end of the sampling stick 1 reaches the circular tube cavity 11, and the circular tube cavity 11 is pre-infused with feces diluent. Shake the device, and the feces on the threaded structure 9 at the lower end of the sampling stick 1 is resuspended in the feces diluent to form a sample mixture. The outer notch 10 of the sampling stick cap 15 is equipped with a limit buckle 2, and the sampling and sample and diluent mixing process will not be operated incorrectly, resulting in detection failure. After the sampling is completed, remove the limit buckle. Buckle 2, the sampling rod 1 and the sampling rod cap 15 can be completely pressed down, the sharp cone at the lower end of the threaded structure 9 can pierce the aluminum foil membrane 32, and the piston 3 is pushed downward to quantitatively squeeze the sample mixture in the circular tube cavity 11 into the receiving groove 14.

Wait until the color band appears, then you can compare the color card and determine the result. The base 5 is spirally sealed with the sampling shell 4 through the first threaded interface 12, and the sealing is good. The test paper shell 6 is connected to the base 5 by adhesive.

[0049] Compared with the prior art structure, the present invention has the following advantages:

[0050] 1. Improve product production efficiency, reduce operating procedures, and the base does not need to be welded by ultrasonic welding.

[0051] 2. Improve product quality, mechanical structure connection ensures the sealing of the base 5, reduces or eliminates the risk of leakage. In the past, products were coated with glue, which affected the detection functionality of the buffer solution and test strips, reduced product sensitivity or caused false positives.

[0052] 3. To improve the convenience of use, you only need to unplug the sampling stick cap 15, take samples, insert the sampling stick cap 15 back and shake it, unplug the limit buckle 2, press the sampling stick cap 15, and read the color band that appears within the specified time to complete the test. In the past, products required unplugging the cover, taking samples, plugging the cover back and shaking it, tearing off the safety sticker, pressing the cover, pulling the cover back to its original position, squeezing the tube body hard, and waiting for the color band to appear. The time when the color band appears is uncontrollable, and the strength of squeezing the tube body by different operators is uncontrollable, resulting in large differences in the interpretation results.

[0053] 4. The sample liquid required for the test can be quantified, and the volume of liquid transferred by the piston 3 of each product is the same, which is not affected by different operators. In the past, different operators pinched the tube body, and the amount of liquid transferred was uncontrollable due to different pinching strengths.

[0054] 5. The test strip rack 7 of the device can be a single-slot single-test rack or a double-test rack, which has a simple structure and is easy to replace.

[0055] Comparative Example 1: Comparison with the Commercial Kit for Helicobacter pylori

[0056] 1. Use the stool sampling and detection integrated device of the present invention and the commercial Helicobacter pylori detection kit (commercial detection card) to detect 20 stool samples respectively. Commercial Helicobacter pylori detection kit (commercial detection card): perform sample preparation, sample addition and read the test sample operations according to the instructions. The obtained data statistics are as follows:

[0057]

[0058]

[0059] Note: In the table, “+” represents a positive test, and “-” represents a negative test.

[0060] 2. It can be seen that the integrated device of the present invention can detect samples accurately and easily without complicated sample processing procedures; since the detection process is carried out in a closed environment, there is no odor and it is friendly to non-professionals (such as home users or non-laboratory doctors); it can also reduce the workload for professionals and can process a large number of samples quickly.

[0061] Comparative Example 2: Comparison with the Hemoglobin / Transferrin Combined Detection Kit

[0062] 1. Use the stool sampling and detection integrated device of the present invention and the commercial occult blood immune double detection kit hemoglobin / transferrin combined detection kit (commercial detection card) to test 20 stool samples respectively. Commercial occult blood immune double detection kit (commercial detection card): follow the instructions to take samples, add samples and read the test samples. The obtained data statistics are as follows:

[0065] Transferrin test results:

[0066]

[0067]

[0068] Note: In the table, “+” represents a positive test, and “-” represents a negative test.

[0069] 2. It can be seen that the present invention can perform two tests on the same biological sample at the same time, without the need for complicated sample processing, and is more convenient for use by non-professionals, such as home users or non-laboratory doctors. When used by professionals, it can reduce the workload and can quickly test a large number of samples.
