Technical Field

[0001] This utility model relates to the field of medical testing technology, specifically a personalized, custom-designed button-type multi-channel testing device. Background Technology

[0002] Reagent test kits are tools used to detect specific components in human body fluids, blood, or other samples. They are widely used in medical, scientific research, and other fields. Their core function is to assess health status or disease status by analyzing biomarkers in samples. Commonly used methods on the market include colloidal gold method, fluorescence method, and microfluidics. The existing patent publication number CN220932989U discloses a multi-channel antigen detection device, including a detection box. The surface of the detection box includes an experimental port and a display group. The interior of the detection box includes a sample elution area and a reagent group. The experimental port is connected to the sample elution area. The bottom of the sample elution area is provided with a channel, and a thin film is provided in the channel. The reagent group includes a sampling area and a reagent strip area. The sample elution area is connected to the sampling area through the channel. It can detect multiple viruses simultaneously, providing convenience for users and saving detection time. The aforementioned patent is not convenient for personalized customization. The detection plates are arranged in sequence, and the sample needs to pass through the detection plates step by step to complete the detection as it flows through the channel to the sampling point. The sample cannot simultaneously contact multiple detection plates to react, which is not conducive to synchronizing the reaction time of multiple detection plates and the amount of sample added, making it inconvenient to use. Utility Model Content

[0003] The purpose of this invention is to provide a personalized, customizable button-type multi-channel detection device to solve the problem in the above-mentioned background technology that the sample needs to pass through the detection plates step by step to complete the detection when flowing through the channel to the sampling point, and the sample cannot simultaneously contact multiple detection plates to react, which is not conducive to the simultaneous reaction time of multiple detection plates and the amount of sample added.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a personalized, custom-designed button-type multi-channel detection device, comprising a detection plate, a flow-limiting component on the top of the detection plate, and humidity-sensing paper and anti-slip pads on the bottom of the detection plate; the detection plate includes a button-shaped circular plate body, a sample loading platform centrally located at the top of the plate body, and multiple reaction zones equidistantly arranged in a ring around the sample loading platform at the top of the plate body, the depth of each of the multiple reaction zones being greater than that of the sample loading platform, different detection objects being placed in the multiple reaction zones, and inclined drainage channels being provided between each of the multiple reaction zones and the sample loading platform, with an opening corresponding to the drainage channel arranged in a ring at equal intervals within the sample loading platform.

[0005] Preferably, the height of the end of the drainage channel connected to the sample loading platform is higher than the height of the end connected to the reaction tank area.

[0006] Preferably, at least two reaction tank areas are provided, and the top of the plate is provided with a label corresponding to the number and position of the reaction tank areas.

[0007] Preferably, the interior of the drainage channel is provided with a hydrophobic coating.

[0008] Preferably, the bottom of the sample loading platform has an upward-facing conical structure.

[0009] Preferably, the flow limiting component includes a sample feeding ring, which is engaged inside the sample feeding support platform. The side wall of the sample feeding ring is provided with a plurality of outlets two corresponding to outlet one in a ring shape. An ear plate is fixedly connected to the outside of the sample feeding ring, and a liquid level groove is provided on the inner side wall of the sample feeding ring.

[0010] Preferably, an adhesive is provided at the center of the bottom of the plate, the humidity sensing paper is adhered to the bottom of the adhesive, and multiple anti-slip pads are provided. The multiple anti-slip pads are fixedly connected to the bottom of the plate and correspond to the number and position of the reaction tank area.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. After the sample is added to the sample loading platform, it flows into the drainage channel from the opening corresponding to the drainage channel, and is simultaneously and quickly and evenly distributed to multiple reaction tank areas. The sample reacts with different analytes set in the multiple reaction tank areas to produce changes. With the help of observation and comparison labels, multiple types of rapid detection can be performed simultaneously. It is convenient to use and can perform multiple types of detection simultaneously, improving detection efficiency. 2. The misaligned design of port two and port one forms a seal, which, combined with the observation of the sample solution level and the position of the level tank, facilitates the determination of the sample addition amount. After the sample is added, the ear plate is moved to rotate the sample addition ring within the sample addition platform. The misaligned port two and port one overlap, allowing the sample to flow smoothly into the reaction tank area. This facilitates precise control of the sample addition amount and enables quantitative release of the sample, effectively avoiding detection errors caused by excessively fast flow rate or unstable flow during sample addition.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: a personalized, custom-designed button-type multi-channel detection device, including a detection plate 1, a flow-limiting component 2 on the top of the detection plate 1, and a humidity-sensing paper 4 and an anti-slip pad 5 on the bottom of the detection plate 1; the detection plate 1 includes a button-shaped circular plate body 11, a sample loading platform 12 centrally located at the top of the plate body 11, and multiple reaction zones 13 equidistantly arranged in a ring around the sample loading platform 12 at the top of the plate body 11, the depth of each of the multiple reaction zones 13 being greater than that of the sample loading platform 12, and different detection substances placed in the multiple reaction zones 13, the multiple reaction zones 13 and the sample loading platform 12 being connected. Inclined drainage channels 14 are provided between the stages 12. The sample loading stage 12 is provided with openings 15 corresponding to the drainage channels 14 in a ring at equal intervals. After the sample is added to the sample loading stage 12, it flows into the drainage channels 14 from the openings 15 corresponding to the drainage channels 14, and is simultaneously and quickly and evenly distributed to the interior of multiple reaction tanks 13. The sample reacts with different analytes set in the multiple reaction tanks 13 to produce changes. With the help of observation and comparison labels 16, multiple types of rapid detection can be performed simultaneously, which is convenient to use and can perform multiple types of detection simultaneously, improving detection efficiency.

[0016] The entire detection plate 1 is 3D printed and has a button-like circular design, ensuring that the sample automatically flows through the drainage channel 14 into the reaction tank area 13 at different locations. The number and overall size of the reaction tank area 13 can be customized according to needs, and it can be used for the simultaneous detection of different liquid samples.

[0017] The height of one end of the drainage channel 14 connected to the sample loading platform 12 is set higher than the height of the end connected to the reaction tank area 13. The height difference design can accelerate the sample flow by gravity, avoid the sample from being stuck in the drainage channel 14, ensure that the flow rate and flow volume of the sample in each drainage channel 14 are kept uniform, prevent the deviation of the test results due to flow differences, and enable the sample to enter the reaction tank area 13 quickly and evenly, providing a stable sample distribution for subsequent multi-type simultaneous detection.

[0018] At least two reaction zones 13 are provided. The top of the plate 11 is provided with labels 16 corresponding to the number and position of the reaction zones 13. The presence of at least two reaction zones 13 allows for simultaneous detection of multiple types of samples. With the use of labels 16, each label 16 is marked with the name of the detection item and colorimetric card for the corresponding reaction zone 13. Before adding samples, operators can quickly identify the detection function of each reaction zone 13 through the labels 16, avoiding operational errors caused by confusion of detection items. The labels 16 can also maintain clear identification even after long-term use or contact with test samples and reagents, ensuring the accuracy and traceability of the detection process.

[0019] The interior of the drainage channel 14 is equipped with a hydrophobic coating, which can significantly reduce the adhesion of the sample to the inner wall of the drainage channel 14, further reducing the possibility of sample residue. For samples or reagents with a certain degree of viscosity, it can effectively avoid the risk of cross-contamination caused by residue. At the same time, the hydrophobic properties can also accelerate the flow rate of the sample, which works synergistically with the height difference design of the drainage channel 14 to ensure that the sample enters the reaction tank area 13 through the drainage channel 14 at a faster speed, thereby improving the overall detection efficiency.

[0020] The bottom of the sample loading platform 12 has an upward-facing conical structure, which allows the sample inside the platform to disperse in all directions under its own gravity and quickly enter the reaction tank area 13 through the drainage channel 14. This effectively prevents the sample from remaining at the bottom edge of the platform 12. At the same time, the smooth transition of the inner wall of the conical structure reduces the resistance to sample flow, ensuring the smoothness and integrity of sample transfer, and improving the sample utilization rate and the reliability of the test results.

[0021] Please see Figure 1 and Figure 5The flow-limiting component 2 includes a sample dispensing ring 21, which is engaged inside the sample dispensing platform 12. Multiple outlets 22, corresponding to outlet 15, are equidistantly arranged in a ring on the side wall of the sample dispensing ring 21. An ear plate 23 is fixedly connected to the outside of the sample dispensing ring 21. A liquid level groove 24 is provided on the inner side wall of the sample dispensing ring 21. By dripping the sample solution into the sample dispensing platform 12, and with the sample dispensing ring 21 engaged within the platform, the outlets 22 are misaligned with outlet 15 to form a seal, allowing for observation of the sample solution. The liquid level and the position of the liquid level tank 24 facilitate the determination of the sample addition amount. After the sample is added, the ear plate 23 is turned to drive the sample addition ring 21 to rotate within the sample addition support platform 12. The misaligned port 22 and port 15 overlap, allowing the sample to flow smoothly into the reaction tank area 13. This facilitates precise control of the sample addition amount. The quantitative release of the sample is completed by simply rotating the sample addition ring 21, effectively avoiding detection errors caused by excessive flow rate or unstable flow during the sample addition process, and further improving the ease of operation and detection accuracy of the device.

[0022] An adhesive 3 is centrally located at the bottom of the plate 11. The humidity sensing paper 4 is adhered to the bottom of the adhesive 3. Multiple anti-slip pads 5 are provided and fixedly connected to the bottom of the plate 11, corresponding to the number and position of the reaction tank area 13. The adhesive 3 ensures that the humidity sensing paper 4 is tightly attached to the bottom of the plate 11. When the ambient humidity changes, the cobalt chloride in the humidity sensing paper 4 combines with moisture to form different substances, causing a color change, which can provide a moisture warning. The anti-slip pads 5 are made of wear-resistant and elastic silicone material, and their bottom is designed with fine corrugated textures, which can significantly increase the friction between the device and the placement surface, preventing the device from sliding or tipping over due to accidental contact during sample addition, reaction, or detection.

[0023] Working principle: During use, the detection plate 1 is placed flat on the table. The anti-slip pad 5 at the bottom of the detection plate 1 increases friction to improve stability. The diluted sample solution is dripped into the sample loading platform 12. The sample loading ring 21 is engaged within the platform 12, and the second opening 22 is misaligned with the first opening 15 to form a seal. The sample solution level and the position of the level tank 24 are observed to determine the sample addition amount. After the sample is added, the lug 23 is moved, causing the sample loading ring 21 to rotate within the platform 12, aligning the misaligned second opening 22 with the first opening 15, allowing the sample to be added. The sample flows into the drainage channel 14 from the opening 15 corresponding to the drainage channel 14, and is simultaneously and quickly and evenly distributed into multiple reaction tank areas 13. The sample reacts with different detection substances set in the multiple reaction tank areas 13 to produce changes. With the help of observation and comparison labels 16, multiple types of rapid detection or multiple virus detection can be performed simultaneously. It is convenient to control the amount of sample added, and can perform multiple types of detection simultaneously while being easy to use, thus improving detection efficiency. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
