Description

Technical Field

[0001] This utility model relates to the field of urine testing equipment technology, and in particular to an integrated nitrate detection device. Background Technology

[0002] Urinary tract infection (UTI) is an inflammation caused by bacteria (most commonly Escherichia coli) invading the urinary system. The principle of nitrate testing is closely related to the metabolic activities of these bacteria.

[0003] Existing equipment requires a series of steps to detect nitrate concentration in patient urine samples, including sampling, sample transfer, manual addition of reaction reagents, re-transfer of the sample into the detection equipment, and completion of the detection. This process is cumbersome. Therefore, it is necessary to invent an integrated nitrate detection device to directly detect nitrate in urine samples. Utility Model Content

[0004] The purpose of this invention is to propose an integrated nitrate detection device to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0006] An integrated nitrate detection device includes a chassis, on which a side groove and a limiting groove communicating with the side groove are provided;

[0007] The slide is slidably mounted on the inner wall of the side trough. The machine housing is equipped with a lifting drive component that drives the slide to slide along the height direction of the side trough. A guide pipe is rotatably mounted on the slide, and a stirring component and a detector are mounted on the guide pipe.

[0008] The drive assembly is mounted on the carriage and drives the guide tube to rotate around the axis of the limiting groove.

[0009] The feeding mechanism is located inside the machine casing. The output end of the feeding mechanism is connected to the feed pipe to quantitatively inject the reaction reagent into the container through the feeding mechanism.

[0010] Preferably, a control panel is installed on the chassis, and an anti-slip support pad is installed on the bottom of the chassis.

[0011] Preferably, a perforated support plate is provided at the bottom of the limiting groove, and an air extraction component is provided on the chassis. The input end of the air extraction component is connected to the limiting groove from below the perforated support plate.

[0012] Preferably, the mixing assembly includes a mixing paddle, a waterproof seat is provided on the feed pipe, the mixing paddle is connected to the waterproof seat, and a scraper is connected to the bottom of the mixing paddle, with the discharge port of the feed pipe located above the scraper.

[0013] Preferably, the detector includes an optical sensor probe.

[0014] Preferably, the feeding mechanism includes a liquid pump, a reagent tank A, and a reagent tank B. The body of the liquid pump is installed inside the casing. The output end of the liquid pump is provided with a water outlet pipe, which is inserted into and communicates with the inside of the guide pipe. The output end of the water outlet pipe rotates coaxially with the guide pipe. The input end of the liquid pump is provided with a tee, which is connected to the output end of the tee. Both reagent tank A and reagent tank B are installed inside the casing. The output end of reagent tank A is provided with a discharge pipe A, which is equipped with a flow valve A. The output end of reagent tank B is provided with a discharge pipe B, which is equipped with a flow valve B. The output ends of discharge pipe A and discharge pipe B are respectively connected to the corresponding input ends of the tee.

[0015] Preferably, each of the reagent tanks A and B is provided with a feed pipe that communicates with its interior, and the end of the feed pipe extending out of the machine casing is threaded with a breathable dustproof cover.

[0016] The beneficial effects of this invention are as follows: This device integrates multiple steps such as sample positioning, precise reagent addition, mixing, and optical detection into one unit, achieving full automation through an advanced control system. Users only need to place the sample and start the program to quickly obtain test results, effectively simplifying the operation process, reducing reliance on operator skills, and significantly improving testing efficiency. The device automatically senses the sample volume through pressure sensing technology, thereby precisely controlling the addition ratio of various reaction reagents and providing ideal conditions for subsequent reactions. The innovative rotary stirring design ensures that urine and reagents are quickly and thoroughly mixed in the container, resulting in a more complete reaction. At the same time, the unique negative pressure fixing mechanism effectively prevents the container from moving or tipping over during stirring, ensuring the safety and stability of the operation process, reducing errors at multiple stages, and making the final nitrate concentration reading more accurate and reliable.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1, as Figures 1-5 As shown, this utility model proposes an integrated nitrate detection device, including a housing 1, a slide 5, a drive assembly 12, and a feeding mechanism. The housing 1 has a side groove 101 and a limiting groove 102 communicating with the side groove 101. A control panel 2 is mounted on the housing 1, and an anti-slip support pad is provided at the bottom of the housing 1. The control panel 2 uses a combination of HMI (Human Machine Interface) and PLC (Programmable Logic Controller). The HMI provides users with an intuitive and user-friendly interface, allowing for easy issuance of various commands via touchscreen. The slide 5 is slidably mounted on the inner wall of the side groove 101. A lifting drive component is provided on the housing 1 to drive the slide 5 to slide along the height direction of the side groove 101. The lifting drive component includes, but is not limited to, a servo electric cylinder 6. The body of the servo electric cylinder 6 is connected to the inner wall of the side groove 101, and the output end of the servo electric cylinder 6 is connected to the slide 5. A guide pipe 7 is rotatably mounted on the slide 5. A stirring assembly and a detector 11 are mounted on the guide pipe 7. The detector 11 includes, but is not limited to, an optical sensor probe. The drive assembly 12 is mounted on the slide 5 and drives the guide tube 7 to rotate around the axis of the limiting groove 102. The drive assembly 12 includes, but is not limited to, gear A121, gear B122, and servo motor 123. Gear A121 is coaxially connected to the guide tube 7. A drive shaft is mounted on the slide 5. Gear B122 is coaxially connected to the drive shaft and meshes with gear A121. The body of the servo motor 123 is mounted on the slide 5. The output end of the servo motor 123 is connected to the drive shaft via a coupling. A sealed cavity is provided on the slide 5. Gears A121 and B122 are both located in the sealed cavity, and lubricating oil is stored in the sealed cavity. The feeding mechanism is located inside the housing 1. The output end of the feeding mechanism is connected to the guide tube 7 to quantitatively inject the reaction reagent into the container through the feeding mechanism.

[0025] It should be noted that the reagent in reagent box A14 is an oxidizing agent, while the reagent in reagent box B15 is a buffer.

[0026] In this embodiment, the urine cup for collecting urine is placed into the limiting groove 102. The servo electric cylinder 6 is activated, which pulls down the slide 5, thereby driving the feed tube 7 and the stirring paddle 9 into the urine cup. Then, the liquid pump 14 is activated, and the flow valves A142 and B152 open synchronously (or asynchronously). The liquid pump 14 draws medicine from the medicine tank 14 and medicine tank B15 and injects it into the urine cup. Next, the servo motor 123 is activated, which drives the gear B122 to rotate, thereby driving the gear A121 and the feed tube 7 to rotate, and then driving the stirring paddle 9 to rotate, so that the urine and medicine are fully mixed and the organic impurities in the urine are decomposed. Then, the optical sensor probe is activated to detect the nitrate content and concentration of the treated solution, and the detection results are directly displayed on the touch screen.

[0027] Example 2, as Figure 2 and Figure 3 As shown, the integrated nitrate detection device proposed in this utility model, compared with Embodiment 1, has a porous support plate 3 at the bottom of the limiting groove 102, and an air extraction component on the casing 1. The input end of the air extraction component is connected to the limiting groove 102 from below the porous support plate 3. The air extraction component includes, but is not limited to, a negative pressure pump 4. The body of the negative pressure pump 4 is installed inside the casing 1. The input end of the negative pressure pump 4 is provided with an air extraction pipe 41, the other end of which is connected to the limiting groove 102. The output end of the negative pressure pump 4 is provided with an exhaust pipe 42, and the output end of the exhaust pipe 42 is connected to the outside.

[0028] It should be noted that a pressure sensor is also provided on the porous support plate 3, and the pressure sensor is electrically connected to the PLC controller.

[0029] In this embodiment, after the urine cup (with uniform specifications) is placed into the limiting groove 102, the pressure sensor measures the total weight of the urine cup to determine the amount of urine sample, which facilitates the automatic determination of the amount of medicine to be added. Then, the negative pressure pump 4 is started to work, and a large suction force is generated on the container through the air holes on the porous support plate 3, so that the container is fixed. When the solution inside the container is stirred, the container will not shake, thereby preventing the container from being lifted or tipped over.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
