[0002] Hematology analyzers, also known as blood cell analyzers, hematology counters, or hematology cytometers, are among the most widely used instruments in hospital clinical laboratories. Current hematology analyzers have numerous components, arranged according to system requirements in relevant parts of the instrument. Each component connects to its corresponding cable from the circuit board via its own connector. However, this assembly method, where each component is installed independently, leads to complex wiring and installation procedures, especially for the fluid circuit components which have numerous parts and a large number of electrical connections, making production, assembly, disassembly, and maintenance inconvenient.

[0038] Specifically, from left to right, the middle of the frame 1 contains a first open oral chamber 10, a middle wiring chamber, and a second open oral chamber 11.

[0039] In a more specific embodiment, the frame 1 includes a front plate 13, a rear plate 14, a bottom plate 15, a middle partition 16, a liquid passage partition 17, and a top plate 18; the front plate 13 and the rear plate 14 are vertically disposed at both ends of the bottom plate 15, the middle partition 16 and the liquid passage partition 17 are spaced apart in the middle of the bottom plate 15, and the middle partition 16 and the liquid passage partition 17 are vertically connected to the front plate 13 and the rear plate 14; the top plate 18 is disposed on top of the middle partition 16 and the liquid passage partition 17, and both ends of the top plate 18 are respectively connected to the front plate 13 and the rear plate 14; the front plate 13, the rear plate 14, the bottom plate 15, the top plate 18, and the side of the middle partition 16 away from the liquid passage partition 17 enclose the first opening. Chamber 10; the front plate 13, the rear plate 14, the bottom plate 15, the middle partition 16, the liquid path partition 17, and the top plate 18 enclose the intermediate wiring chamber; the front plate 13, the rear plate 14, the bottom plate 15, the top plate 18, and the liquid path partition 17 enclose the side away from the middle partition 16 to form the second open mouth chamber 11; the power supply assembly 2 is disposed on the side of the rear plate 14 away from the front plate 13, the control circuit board 3 is disposed on the side of the top plate 18 away from the bottom plate 15, the reagent supply assembly 4 is disposed in the second open mouth chamber 11 and on the side of the front plate 13 away from the rear plate 14, and the automatic sample injection assembly 5 is disposed on the side of the front plate 13 away from the rear plate 14.

[0040] In this embodiment, refer to Figures 1 to 4Using the base plate 15 as the mounting substrate, the front plate 13 and the rear plate 14 are vertically arranged at both ends of the base plate 15. The middle partition plate 16 and the liquid passage partition plate 17 are spaced apart in the middle of the base plate 15 and vertically connected to the front plate 13 and the rear plate 14. The top plate 18 is arranged on top of the middle partition plate 16 and the liquid passage partition plate 17. Thus, the space enclosed by the front plate 13, the rear plate 14, the base plate 15 and the top plate 18 are divided into the first open cavity chamber 10, the middle wiring chamber and the second open cavity chamber 11 by the middle partition plate 16 and the liquid passage partition plate 17. The power supply assembly 2 is installed on the side of the rear plate 14 away from the front plate 13, the control circuit board 3 is installed on the side of the top plate 18 away from the bottom plate 15, the reagent supply assembly 4 is installed in the second oral cavity 11 and on the side of the front plate 13 away from the rear plate 14, and the automatic sample injection assembly 5 is installed on the side of the front plate 13 away from the rear plate 14. By installing all the modular components of the blood cell analyzer within the visible range and within the reach of the human hand, the maintainability is improved.

[0041] For details, please refer to Figure 5 The control circuit board 3 serves as the control unit of the blood cell analyzer. It mainly consists of a main control board 30, a drive board 31, a power supply board (not shown), a hard disk 32, and other boards. The layout of each board in the control circuit board 3 is determined primarily by the electrical connection relationships of the electrical components. The control circuit board 3 is installed on the side of the top plate 18 away from the bottom plate 15, meaning it is located at the top of the blood cell analyzer. This provides good hydraulic and electrical isolation, and the centralized layout of the boards facilitates assembly and maintenance.

[0042] In a more specific embodiment, the blood cell analyzer provided by this utility model further includes a first plate heating module 70 and a heat dissipation component 71; the first plate heating module 70 and the heat dissipation component 71 are both disposed on the side of the rear plate 14 away from the front plate 13; the first plate heating module 70 and the heat dissipation component 71 are both electrically connected to the control circuit board 3.

[0043] In this embodiment, refer to Figure 6 On the side of the rear panel 14 away from the front panel 13, a first flat heating module 70 and a heat dissipation component 71 are also installed. The first flat heating module 70 is used to heat the blood routine detection component 6, and the heat dissipation component 71 is used to dissipate heat from the control circuit board 3 and the blood routine detection component 6.

[0044] Specifically, the first plate heating module 70 is located on the rear plate 14 at a position corresponding to the first open oral chamber 10. The main function of the first plate heating module 70 is to reduce the influence of ambient temperature on reagents. It mainly provides heating for reagents delivered to the blood routine testing component 6, such as the optical sheath fluid in the optical detection component of the blood routine testing component 6, the diluent in the HGB module 62 and RBC module 63 of the blood routine testing component 6, and the cleaning fluid, to ensure that performance requirements are met. Since the blood routine testing component 6 is installed in the first open oral chamber 10, installing the first plate heating module 70 on the rear plate 14 at a position corresponding to the first open oral chamber 10 makes the distance between the pipeline of the first plate heating module 70 and the blood routine testing component 6 relatively short, resulting in less heat loss from the pipeline and better ensuring temperature control performance. Furthermore, the first flat heating module 70 is fixed to the rear plate 14 by a heating mounting plate (not shown), and the heating mounting plate is located inside the first open cavity 10. The heating mounting plate can be disassembled and installed by pulling it out from the front and back, and has good manufacturability and maintainability. The edge of the heating mounting plate is provided with a bent arc structure to facilitate pulling out.

[0045] More specifically, the heat dissipation component 71 is located on the upper end of the rear plate 14. The heat dissipation component 71 mainly dissipates heat from the control circuit board 3 installed on the top plate 18 and the blood routine detection component 6 installed in the first open oral cavity 10. The heat dissipation component 71 is installed at the upper end of the rear partition, and the bottom plate 15 is provided with an air inlet. Thus, the heat dissipation component 71 draws away the heat from the control circuit board 3 and the blood routine detection component 6, thereby meeting the heat dissipation requirements of the whole machine.

[0046] In one embodiment, see Figure 6The rear panel 14, on the side away from the front panel 13, mainly houses components such as the power supply assembly 2, the first flat heating module 70, the heat dissipation assembly 71, the grounding post 72, and the external reagent connector 73. The layout of each component is mainly determined by the electrical connection relationship and wiring. The power supply assembly 2 includes a power box 20 and a power switch 21. Both the power box 20 and the power switch 21 are installed on the side of the rear panel 14 away from the front panel 13. The installation position of the power box 20 corresponds to the intermediate wiring chamber, and the power switch 21 is located below the power box 20. The power switch 21 is electrically connected to the power box 20, and the power box 20 is electrically connected to the control circuit board 3. The advantages of this layout are mainly: 1. Good liquid-electric isolation. The installation position of the power box 20 corresponds to the intermediate wiring chamber, eliminating the risk of liquid leakage and eliminating the need for a special sealing design in the structure; 2. High space utilization; 3. The control circuit board 3 is located on the top panel 18, and the power switch 21 is located below the power box 20. Therefore, when wiring, the upper end of the power box 20 can directly pass through the top panel 18 to connect to the control circuit board 3, and the lower end of the power box 20 can directly connect to the power switch 21, resulting in a short wiring path and good manufacturability. Furthermore, the external reagent connector 73 is located at the lower end of the rear plate 14 on the side away from the front plate 13 and at a position corresponding to the second open oral chamber 11. The external reagent connector 73 is connected to the reagent supply assembly 4 and is used to connect the required externally supplied reagents to the reagent supply assembly 4.

[0047] In a more specific embodiment, the blood routine testing component 6 includes a sampling component 60, a reaction incubation module 61, an HGB module 62, an RBC module 63, a second plate heating module 64, and an optical detection component. The sampling component 60, the reaction incubation module 61, the HGB module 62, the RBC module 63, and the second plate heating module 64 are all disposed on the side of the partition 16 away from the liquid path partition 17, and the reaction incubation module 61, the HGB module 62, the RBC module 63, and the second plate heating module 64 are all located below the sampling component 60, while the optical detection component is disposed above the sampling component 60. The sampling component 60, the reaction incubation module 61, the HGB module 62, the RBC module 63, the second plate heating module 64, and the optical detection component are all electrically connected to the control circuit board 3. The reaction incubation module 61, the HGB module 62, and the RBC module 63 are connected to the reagent supply component 4, and the optical detection component is connected to the reaction incubation module 61.

[0048] In this embodiment, refer to Figure 7The sampling component 60, reaction incubation module 61, HGB module 62, RBC module 63, second plate heating module 64 and optical detection component are all located in the first open oral chamber 10, and the reaction incubation module 61, HGB module 62, RBC module 63 and second plate heating module 64 are located below the sampling component 60, and the optical detection component is located above the sampling component 60. The sampling component 60 is used to aspirate blood samples from the blood sample tubes delivered by the autosampler 5 and distribute the blood samples to the reaction incubation module 61, the HGB module 62, and the RBC module 63. The sampling component 60 is mounted on the partition plate 16. Since the autosampler 5 is located on the side of the front plate 13 away from the rear plate 14, one end of the sampling component 60 penetrates the front plate 13, so that the sampling component 60 can aspirate blood samples from the blood sample tubes delivered by the autosampler 5. At the same time, the sampling component 60 is located directly above the reaction incubation module 61, the HGB module 62, and the RBC module 63. The sampling component 60 can perform aspiration and distribution actions through vertical and horizontal two-dimensional movements.

[0049] The reaction incubation module 61 is located on the side of the partition 16 near the front plate 13. The reaction incubation module 61, the second plate heating module 64, the HGB module 62, and the RBC module 63 are arranged sequentially from front to back on the partition 16. This arrangement is primarily determined by the reagent reaction principle and fluid timing, and can accelerate sample testing. The reaction incubation module 61, HGB module 62, and RBC module 63 are all connected to the reagent supply component 4 to obtain the required reagents. Specifically, the reaction incubation module 61 is also connected to the optical detection component. The reaction incubation module 61 is used to perform sample mixing and incubation functions for the DIFF / WNB / RET detection channels, providing the optical detection component with the incubated sample to be tested. The optical detection component is used to detect the five-part differential parameters of white blood cells in the sample. The HGB module 62 is used to determine the concentration of hemoglobin in blood cells in the blood sample. The RBC module 63 is used to count and detect RBC (red blood cells) / PLT (platelets) in the blood sample. The second plate heating module 64 is used to heat the diluent samples in the HGB module 62 and RBC module 63. The second plate heating module 64 is positioned on the side of the HGB module 62 near the reaction incubation module 61, which makes high space utilization. Furthermore, the position of the second plate heating module 64 is close to the HGB module 62 and RBC module 63, and the heating pipeline is very short, thus better meeting the heating performance requirements.

[0050] In one embodiment, see Figure 7A waste discharge valve assembly 66 is also provided on the side of the partition 16 away from the liquid circuit partition 17. The waste discharge valve assembly 66 is connected to the waste discharge port at the bottom of the reaction incubation module 61, HGB module 62, and RBC module 63. Therefore, the waste discharge valve assembly 66 is installed on the side of the RBC module 63 away from the HGB module 62, following the principle of proximity. Furthermore, since the diaphragms of each waste discharge valve in the waste discharge valve assembly 66 are easily damaged and have a high maintenance probability, convenient maintenance is required. The waste discharge valve assembly 66 is installed on the side of the partition 16 away from the liquid circuit partition 17, so that the waste discharge valve assembly 66 is located in the first open cavity chamber 10, and there are no other parts directly in front of the waste discharge valve assembly 66, providing a large operating space and fully meeting maintenance requirements. Furthermore, since the reaction incubation module 61, HGB module 62 and RBC module 63 are prone to leakage, a leakage detection device 67 can be installed on the reaction incubation module 61. The leakage detection device 67 is used to detect whether there is leakage in the reaction incubation module 61, HGB module 62 and RBC module 63.

The optical valve assembly 650 controls the flow of the connecting pipe between the optical detection module 651 and the reaction incubation module 61. The optical detection module 651 is primarily used to detect the five-part differential parameters of white blood cells in the sample.

Preferably, the optical detection module 651 is positioned on the upper end of the optical partition 19, near the rear plate 14, allowing it to avoid vibration sources and reduce interference.
