[0029] The injection mechanism includes an injection pump assembly, an injection needle 1, and an injection valve 2. The injection valve 2 is a six-way injection valve 2. The injection pump assembly is connected to the first port 21 of the injection valve 2, and the injection needle 1 is connected to the second port 22 of the injection valve 2.

[0030] The separation mechanism includes an eluent group, a mixer 4, and a chromatography separator 5. The eluent group is connected to the fifth port 25 of the injection valve 2, the chromatography separator 5 is connected to the sixth port 26 of the injection valve 2, and the two ends of the mixer 4 are connected to the third port 23 and the fourth port 24 of the injection valve 2.

[0031] The testing mechanism includes a filter 6 and a tester 7. The filter 6 is located between the mixer 4 and the chromatography separator 5, and the tester 7 is connected to the chromatography separator 5.

[0032] In some embodiments of this application, the injection pump assembly includes a first injection pump 31, a second injection pump 32, and an injection valve 3. The first injection pump 31 is connected to the injection valve 3, the second injection pump 32 is connected to the injection valve 3, and the injection valve 3 is connected to the first port 21 of the injection valve 2.

[0033] The syringe pump set is equipped with multiple syringe pumps, which can be controlled according to the testing requirements to achieve the best testing results.

[0034] In some embodiments of this application, the eluent assembly includes a first eluent tank 81, a second eluent tank 82, a first separation pump 83, and a second separation pump 84.

[0035] The first eluent storage tank 81 or the second eluent storage tank 82 is drawn by the first separation pump 83 and the second separation pump, and the eluent is delivered to the mixer 4. The presence of multiple corresponding eluent storage tanks and separation pumps ensures that the concentration of the eluent meets the testing requirements.

[0036] In some embodiments of this application, the separation mechanism further includes a separation valve 8, which is disposed between the injection valve 3 and the first separation pump 83, and between the injection valve 3 and the second separation pump 84.

[0037] In some embodiments of this application, the mixer 4 includes a mixing tank 41, a stirring shaft 42, a temperature sensor 43, and a heater 44.

The waste liquid tank 9 is typically designed with sufficient capacity to store a certain amount of waste liquid and may be equipped with a level sensor to monitor the waste liquid level and alert operators to clean it when necessary. This design not only improves the automation level of the testing device but also reduces the opportunity for operators to have direct contact with waste liquid, lowering potential health risks.

After receiving these signals, the display device 10 presents the detection results to the user in the form of numbers, charts, images, or other visualizations through a graphical user interface (GUI), so that the user can intuitively understand the detection results.

[0044] During testing, the injection needle 1 and the injection pump assembly control the blood sample to be delivered to the injection valve 2 through the first port 21 and the second port 22, and then into the mixer 4. At the same time, the eluent assembly controls the eluent to enter the mixer 4 through the fifth port 25. The mixer 4 mixes the test sample and then outputs the value detector through the fourth port 24 for testing.
