[0002] Urine testing is a routine test item in modern medical engineering and clinical medicine, and is one of the three major routine tests. Urine protein analyzer is a special instrument for clinical urine analysis combined with reagents made using dry chemical principles. The detection reagent changes color according to the content of several specific components in urine. The urine protein analyzer identifies the color change after the urine combines with the reagent, converts it into the component content, and outputs a test report.

In order to save time, in most cases, samples are collected and then tested in a centralized manner; this requires a relatively long waiting time from sampling to testing, and sometimes even the samples collected on the same day are not arranged for testing until the next day. Urine samples are stored in test tubes, lacking insulation, and will inevitably cool down over time, making it very different from the human body temperature, especially in winter. The detection mechanism on the existing urine protein analyzer lacks a heating device, which may cause inaccurate detection when testing urine samples that have been sampled for a long time, affecting clinical diagnosis; in serious cases, it may even cause medical accidents.

A plurality of detection boxes 3 are arranged in the sample temporary storage component, the sample extraction mechanism and the reagent extraction mechanism are respectively connected to the sample temporary storage component, the sample extraction mechanism can extract the urine sample to be detected into each detection box 3, and the reagent extraction mechanism can extract the detection reagent into each detection box 3 respectively. The detection box 3 is used to store a mixed solution of a urine sample and a detection reagent, and the detection drive component is used to drive the detection box 3 to align with the optical detection head 2 respectively.

[0022] During the test, the sample extraction mechanism is controlled to extract the urine sample into the test box 3, and the reagent extraction mechanism is controlled to extract the test reagent into the test box 3, so that the urine sample and the test reagent react fully in the test box 3. Then the test drive component is controlled to drive the sample temporary storage component to rotate, driving the test box 3 to move until the test box 3 moves to align with the optical test head 2; then the optical test head 2 is controlled to detect the mixed solution in the test box 3, and the test results are transmitted to the controller, thereby realizing the detection function of the sample urine.

[0023] A heating device is provided on the sample temporary storage component, the heating device is electrically connected to the controller, and the heating device is connected to the detection box 3, and is used to heat the mixed solution in the detection box 3. In specific operation, after the urine sample and the detection reagent are extracted into the detection box 3, the heating device can be controlled to work, and the mixed solution in the detection box 3 is heated by the heating device, so that it can be heated to a temperature equal to the human body temperature, thereby improving the accuracy of the detection and avoiding misjudgment of clinical diagnosis caused by inaccurate detection.

[0024] The sample temporary storage assembly includes a turntable 4, and the detection box 3 is detachably connected to the turntable 4. A transmission shaft 5 is fixedly installed on the lower end surface of the turntable 4, and the transmission shaft 5 is connected to the output end of the detection drive assembly. During detection, the detection drive assembly drives the transmission shaft 5 to rotate and then drives the turntable 4 to rotate, thereby driving the detection box 3 to a position corresponding to the optical detection head 2. The detection box 3 and the turntable 4 are detachably connected, so that different types of detection boxes 3 can be easily replaced.

[0025] The heating device includes a heating plate 6. A mounting groove 41 is provided on the lower end surface of the turntable 4. The heating plate 6 is limitedly installed in the mounting groove 41 so that the heating plate 6 is connected and fixed to the turntable 4. The heating plate 6 is electrically connected to the controller through wires. The controller outputs current to enable the heating plate 6 to generate heat, thereby heating the turntable 4, and then transmitting the temperature to the detection box 3, thereby heating the mixed solution in the detection box 3.

[0026] The outer cover of the turntable 4 is provided with a heat preservation cover 7, and the heat preservation cover 7 is slidably matched with the turntable 4, that is, the turntable 4 can rotate freely in the heat preservation cover 7, and the heat preservation cover 7 is fixedly connected with the detection mounting frame 1, and the heat preservation cover 7 is made of heat-insulating material.

[0027] In other embodiments, the insulation sleeve 7 may be filled with insulation materials such as insulation cotton and heat insulating cotton to improve the insulation effect.

[0028] A detection notch 71 is provided on the insulation sleeve 7 at a position corresponding to the optical detection head 2. The detection notch 71 facilitates the optical detection head 2 to detect the mixed solution in the detection box 3 in the turntable 4, thereby improving the working stability.

[0029] like Figure 1 As shown, the detection drive assembly includes a detection drive motor 8, which is fixedly mounted on the detection mounting frame 1, and is electrically connected to the controller. A transmission assembly is provided on the output end of the detection drive motor 8, and the transmission assembly is connected to the transmission shaft 5. By controlling the detection drive motor 8 to work, the transmission assembly can be driven to move, thereby driving the transmission shaft 5 and the turntable 4 to rotate, thereby realizing the function of transporting the detection box 3 to a position aligned with the optical detection head 2.

[0030] Specifically, the transmission assembly includes a detection drive wheel 9 and a detection drive belt 10. The detection drive wheel 9 is connected to the output end of the detection drive motor 8. The detection driven wheel 11 is sleeved on the transmission shaft 5. The detection drive belt 10 is sleeved on the detection drive wheel 9 and the detection driven wheel 11. When working, the detection drive motor 8 is controlled to work, the detection drive wheel 9 is driven to rotate, and the detection drive wheel 9 drives the detection drive belt 10 to move, thereby driving the detection driven wheel 11 to rotate, and the detection driven wheel 11 drives the transmission shaft 5 and the turntable 4 to rotate, so as to realize the function of driving the detection box 3 to align with the optical detection head 2.

[0031] In order to improve the accuracy of control, a detection sensor 12 is installed on the detection mounting frame 1, and the detection sensor 12 is connected to the controller. The transmission shaft 5 is sleeved with an induction toothed disc 13, and a plurality of induction convex teeth 14 are provided on the induction toothed disc 13. Each induction convex tooth 14 is respectively arranged in correspondence with the position where the mixed solution is stored on each detection box 3 in the turntable 4, and each induction convex tooth 14 can be connected with the detection sensor 12 respectively. In specific operation, the transmission shaft 5 will drive the induction toothed disc 13 to rotate. When the transmission shaft 5 drives the next induction convex tooth 14 on the induction toothed disc 13 to connect with the detection sensor 12, then at this time, the next position for storing the mixed solution in the detection box 3 also moves to the position corresponding to the optical detection head 2; then the detection sensor 12 can be used to feedback a signal to control the detection drive motor 8 to pause, so that the optical detection head 2 can detect the mixed solution in the detection box 3. Through the cooperation of the detection sensor 12 and the induction toothed disc 13, the alignment of the detection box 3 and the optical detection head 2 can be accurately controlled, and the stability of detection and the accuracy of control can be improved.

[0032] Working principle:

[0033] First, the sample extraction mechanism is controlled to extract the urine sample into the detection box 3, and then the reagent extraction mechanism is controlled to extract the detection reagent into the detection box 3. Then the heating plate 6 is controlled to work, the turntable 4 is heated, and then the temperature is transmitted to the detection box 3, so as to heat the mixed solution in the detection box 3, and the temperature of the mixed solution is heated to the same as the human body temperature. The urine sample and the detection reagent will fully react in the detection box 3. Then the detection drive motor 8 is controlled to work, the detection drive wheel 9 is driven to rotate, the detection drive wheel 9 drives the detection transmission belt 10 to move, thereby driving the detection driven wheel 11 to rotate, the detection driven wheel 11 drives the transmission shaft 5 and the turntable 4 to rotate, and the transmission shaft 5 drives the turntable 4 and the induction gear disk 13 to rotate synchronously. When the corresponding sensing convex teeth 14 on the sensing toothed disk 13 are connected with the detection sensor 12, the detection sensor 12 feeds back a signal to the controller, and the controller immediately controls the detection drive motor 8 to stop working; at this time, the turntable 4 also happens to drive the detection box 3 containing the mixed solution to move to the position corresponding to the optical detection head 2, and then controls the optical detection head 2 to detect the mixed solution in the detection box 3, thereby completing the detection operation of the sample urine.
