DETAILED DESCRIPTION

[0041] The exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, and are not intended to exhaust all possible modes of the present invention, nor to limit the scope of the present invention.

[0042] like Figure 1 As shown, the present disclosure provides a feces collection and detection device, which includes a feces collector 1 and a detection plug 2. The feces collector 1 can collect feces samples and contain diluent. The feces sample and the diluent are mixed to form a sample liquid. The feces collector 1 is inserted into the detection plug 2.

[0043] Detection card plug 2 pack test paper 222 and sample collection part 223 (shown in Figure 4a , Figure 4b ), the test paper 222 can be a colloidal gold immunochromatography test paper, which is used to detect fecal properties, such as hemoglobin, Helicobacter pylori, etc. The sample collection part 223 is used to hold the sample liquid, and the held sample liquid is used for observation under a microscope (described in detail later).

[0044] like Figure 2a and Figure 2b As shown, the feces collector 1 includes a coaxially arranged collecting rod 11 and a main pipe 12. The main pipe 12 has openings at both ends. The opening at one end of the main pipe 12 is open, and the opening at the other end is sealed by a sealing element 60 (such as aluminum foil). The main pipe 12 has a first chamber 121 and a second chamber 122 arranged along its axial direction. The first chamber 121 is close to the other end of the main pipe 12 and is used to contain a diluent. The second chamber 122 is close to one end of the main pipe 12 and is connected to the open opening of the main pipe 12.

[0045] The collecting rod 11 passes through the open opening of the main tube 12 and is inserted into the main tube 12 along its axial direction. A part of the collecting rod 11 is surrounded by the main tube 12, and another part is exposed from the main tube 12. The collecting rod 11 has a first collecting part 111 and a second collecting part 112 arranged along its axial direction. The first collecting part 111 and the second collecting part 112 are both used to collect fecal samples. When the collecting rod 11 is inserted into the main tube 12, the first collecting part 111 is located in the first chamber 121 so that the fecal sample of the first collecting part 111 contacts the diluent, and the second collecting part 112 is located in the second chamber 122 so that the feces of the second collecting part 112 is exposed to the air of the second chamber 122.

[0046] When the feces collector 1 is assembled, the diluent in the first chamber 121 is isolated from the outside of the first chamber 121. For example, a sealing ring 50 is provided between the first collecting part 111 and the second collecting part 112 of the collecting rod 11. The sealing ring 50 is used to seal the collecting rod 11 and the main pipe 12, which separates the first chamber 121 from the second chamber 122.

[0047] The outer periphery of the feces collector 1 may have a first rubber coating 41 , which is used to seal the gap between the feces collector 1 and the detection plug 2 . Specifically, the first rubber coating 41 may be provided on the outer periphery of the portion of the collecting rod 11 exposed from the main pipe 12 .

[0048] The outer periphery of the collecting rod 11 may have a second rubber coating 42 for sealing the gap between the collecting rod 11 and the main tube 12 . Specifically, the second rubber coating 42 may be disposed on the outer periphery of the portion of the collecting rod 11 located inside the main tube 12 .

[0049] The main pipe 12 may be made of a transparent material, such as a highly transparent plastic injection molded part.

[0050] like Figures 3a to 5b As shown, the detection card plug 2 includes a detection cylinder 22 and a mounting frame 21, the mounting frame 21 is installed in the detection cylinder 22, the detection test paper 222 and the sample collection part 223 are installed on the mounting frame 21, and the sample collection part 223 and the detection test paper 222 can be installed on the mounting frame 21 by pasting or carding. The detection card plug 2 may include multiple detection test papers 222 to detect different properties of feces.

[0051] The detection cylinder 22 includes a sample liquid receiving space 220 for receiving the sample liquid, and the sample liquid receiving space 220 is located at the bottom of the detection cylinder 22. The detection plug 2 also includes a puncturing mechanism 221, which is installed at the bottom of the detection cylinder 22 in the detection cylinder 22.

[0052] When the feces sampling device 1 is inserted into the detection tube 22 , the piercing mechanism 221 pierces the sealing element 60 and is inserted into the interior of the main tube 12 , so that the sample liquid in the feces sampling device 1 (in the first chamber 121 ) flows out of the feces sampling device 1 and enters the sample liquid receiving space 220 .

[0053] The liquid inlet end of the test paper 222 and the liquid inlet end of the sample collecting part 223 are both located at the bottom of the mounting frame 21. When the fecal sampler 1 is inserted into the test tube 22, the sample liquid first enters the bottom of the test tube 22 and is then filtered by the filter element 224 (described in detail later). The filtered sample liquid enters the test paper 222 from the liquid inlet end of the test paper 222 and enters the sample collecting part 223 from the liquid inlet end of the sample collecting part 223.

[0054] The detection card plug 2 also includes a filter 224, which is used to filter large particles in the sample liquid. The filter 224 is installed at the bottom of the mounting frame 21. The filter 224 is located between the sample liquid receiving space 220 and the sample collecting part 223, and is located between the sample liquid receiving space 220 and the detection test paper 222. For example, the filter 224 is installed on one side of the mounting frame 21, and the detection test paper 222 and the sample collecting part 223 are installed on the other side of the mounting frame 21 opposite to the above-mentioned one side.

[0055] In this way, the sample liquid is first filtered by the filter element 224 before contacting the test paper 222 and the sample collection portion 223, thereby removing large particles in the sample liquid.

[0056] The sample liquid receiving space 220, the filter element 224, the liquid inlet end of the sample collection part 223 and the liquid inlet end of the test paper 222 are all located at the bottom of the test plug 2, and the sample liquid can quickly enter the test paper 222 and the sample collection part 223, and the sample liquid can be reliably filtered.

[0057] The filter element 224 may include a filter screen, which may be 80 meshes to 100 meshes. The filter screen may be made of stainless steel or plastic. The filter element 224 may be mounted on the mounting frame 21 by hot sealing or clamping.

[0058] The outer periphery of the mounting frame 21 may have a third rubber package 43 , and the third rubber package 43 is used to seal the gap between the mounting frame 21 and the detection tube 22 .

[0059] By providing the first rubber package 41, the second rubber package 42 and the third rubber package 43, the internal space of the device can be completely sealed, so that the feces sampling device 1 and the detection card plug 2 are sealedly connected, and the feces sampling device 1 and the detection card plug 2 contain the sample liquid in a sealed manner, that is, the feces sampling device 1 and the detection card plug 2 are sealedly connected, the collection rod 11 and the main pipe 12 are sealedly connected, and the detection tube 22 and the mounting frame 21 are sealedly connected, thereby isolating the odor during the detection process.

[0060] An observation window 210 may be provided at a position of the mounting frame 21 aligned with the second collection portion 112 , thereby facilitating observation of the condition of the sample, such as the properties and color of the sample.

[0061] The sample collecting portion 223 may be located below the second collecting portion 112 of the stool collecting stick 11 , and the test paper 222 may be located on the side of the sample collecting portion 223 .

[0062] like Figure 6 As shown, the sample collection portion 223 may include a glass slide 2231, a cover glass 2232, an absorbent pad 2234, an adsorbent 2235 and a staining pad 2233, the cover glass 2232 covers the glass slide 2231, a liquid storage cavity 2236 is formed between the glass slide 2231 and the cover glass 2232, the adsorbent 2235 is disposed in the liquid storage cavity 2236, and the adsorbent 2235 can adsorb cells and microorganisms in the sample liquid.

[0063] The absorbent pad 2234 and the dye pad 2233 are combined with the surface of one side of the slide glass 2231, and the absorbent pad 2234 is located downstream of the liquid storage chamber 2236 in the liquid inlet direction A of the sample collection part 223 to absorb liquid, such as absorbing excess liquid on the adsorbent 2235. The cover glass 2232, the slide glass 2231, the dye pad 2233 and the absorbent pad 2234 together form the liquid storage chamber 2236.

[0064] The absorbent pad 2234 and the dyeing pad 2233 include absorbent materials. Compared with the absorbent pad 2234, the dyeing pad 2233 also has a dyeing substance, which can dye the cells and microorganisms in the sample liquid. The dyeing pad 2233 is located upstream of the liquid storage chamber 2236 in the liquid inlet direction A, so that the sample liquid can be retained in the liquid storage chamber 2236 after passing through the dyeing pad 2233.

[0065] The cells and microorganisms in the sample liquid are stained by the staining pad 2233 and have color, so they can be easily observed under a microscope.

[0066] The sample collection portion 223 may include a plurality of (two or more) sample collection units, and the dye pad 2233 of each sample collection unit dyes different substances, for example, the dye pad 2233 of each sample collection unit dyes different types of cells and microorganisms.

[0067] The adsorbent 2235 may include, for example, a nitrocellulose membrane 2221, or other materials that can adsorb cells and microorganisms. Under the adsorption of the adsorbent 2235, the cells and microorganisms in the sample liquid are suitable for being observed under a microscope.

[0068] In other embodiments, the nitrocellulose membrane may be replaced by non-woven fabric, glass fiber paper, polyester cellulose membrane, blood filter membrane, or other materials that can adsorb cells and microorganisms.

[0069] The adsorber 2235 can also be used to adsorb cells, so that when the stool collection and detection device is used in conjunction with a microscope, the cells in the sample liquid can be observed.

[0070] In other embodiments, the sample collection portion 223 may not have the adsorbent 2235, and the liquid storage chamber 2236 is configured to allow the sample liquid to be retained in the liquid storage chamber 2236 under the action of capillary force, so that the cells and microorganisms in the sample liquid are also suitable for being observed under a microscope. The absorbent pad 2234 is used to absorb the liquid in the liquid storage chamber 2236, for example.

[0071] The liquid storage chamber 2236 of the sample collection portion 223 contains sample liquid, and the sample liquid is adsorbed on the adsorber 2235 or retained in the liquid storage chamber 2236 under the action of capillary force, so that it is suitable for observation under a microscope. The stool detection device not only has the traditional function of detecting stool properties, but also has the function of observing cells and microorganisms in conjunction with a microscope.

[0072] In other embodiments, the sample collection portion 223 may not have a cover glass 2232. When the fecal sampler 1 is inserted into the detection plug 2, the inner wall of the detection cylinder 22 of the detection plug 2 can play the role of a cover glass 2232, forming a liquid storage cavity 2236 together with the slide 2231, the staining pad 2233 and the absorbent pad 2234, and the portion of the detection cylinder 22 corresponding to the liquid storage cavity 2236 is made of transparent material.

[0073] In other embodiments, the glass slide 2231 may be replaced by a plastic sheet or other supporting sheets having a supporting function.

[0074] like Figure 7 As shown, the test paper 222 includes a nitrocellulose membrane 2221, a sample pad 2222, a gold label pad 2223 and a water absorbent pad 2224. The C line and T line of the dry particles are pre-sprayed on the nitrocellulose membrane 2221. The sample liquid first enters the sample pad 2222 along the chromatography direction B and is chromatographed. The gold label pad 2223 performs color development on the sample liquid. Finally, the water absorbent pad 2224 absorbs the excess liquid on the nitrocellulose membrane 2221. The C line and T line will be colored according to the performance of the sample.

[0075] Two different antibodies are fixed on the C line and T line, respectively, which recognize different antigenic determinants. Among them, the T line antibody recognizes the antigen to be tested, and the C line antibody recognizes the colloidal gold-coupled antibody. Colloidal gold particles (colloidal gold is a color marker and is coupled with an antibody) are distributed on the surface of the gold label pad 2223 (colloidal gold binding pad). The red color displayed by the C line and T line is the result of a large amount of colloidal gold aggregation.

[0076] When the sample liquid flows along the chromatographic direction B, it will drive the colloidal gold particles to move. After the excess colloidal gold particles reach line C, their coupled antibodies will combine with the antibodies on line C, and the colloidal gold particles will accumulate in large quantities and appear red.

[0077] When the sample liquid reaches the gold label pad 2223, if the sample liquid contains the antigen to be tested, the colloidal gold-coupled antibody will recognize and bind to the antigen to be tested. The sample liquid continues to flow forward, and when the sample liquid reaches the T line, the antibody of the T line will also bind to the antigen to be tested, forming a three-layer structure of "T line antibody-antigen to be tested-colloidal gold-coupled antibody". When there is no antigen to be tested, the T line antibody cannot catch the colloidal gold-coupled antibody, so the clinical interpretation result is that the T line is colored for positive, and the T line is not colored for negative.

[0078] The device is used in conjunction with an external microscopic photographic device to achieve the function of observing the properties and color of feces. The external microscopic device may include an electronic reflection microscopic device, so as to collect images of samples for easy observation.

[0079] It should be understood that the above embodiments are only exemplary and are not intended to limit the present invention. Those skilled in the art may make various modifications and changes to the above embodiments under the guidance of the present invention without departing from the scope of the present invention.
