[0048] As Figures 1 to 3 shown, this embodiment provides a blood analyzer, which includes a housing 10 and a main unit. The main unit is disposed inside the housing 10; the main unit includes a frame 20, and the frame 20 includes a front plate 21 and a rear plate 22 which are oppositely arranged, and a bottom plate 23 and a top plate 24 which are oppositely arranged.

[0049] To accommodate the arrangement of multiple components in the main space, the frame 20 further includes a second partition plate 26. The second partition plate 26 is parallel to and spaced from the first partition plate 25, perpendicular to the front plate 21 and the rear plate 22, and disposed within the main space. The second partition plate 26 divides the main space into a second space and a third space that communicate with each other. The second space and the third space are located on both sides of the second partition plate 26 respectively, and the second space is located between the first partition plate 25 and the second partition plate 26.

[0050] Specifically, the housing 10 includes a front shell 11, a left shell 13, a right shell 14, a top shell 15, and a rear shell 12 that are fixedly connected in cooperation with each other. The front shell 11 is disposed outside the front plate 21, the top shell 15 is disposed outside the top plate 24, the rear shell 12 is disposed outside the rear plate 22, and the left shell 13 and the right shell 14 are oppositely disposed on both sides of the frame 20.

[0051] In this embodiment, both the first partition plate 25 and the second partition plate 26 are perpendicular to the bottom plate 23 and the top plate 24. The second space is located between the first partition plate 25 and the second partition plate 26, the first space is located between the right shell 14 and the first partition plate 25, and the third space is located between the left shell 13 and the second partition plate 26.

[0052] In this embodiment, the bottom plate 23 is disposed horizontally, and the first partition plate 25 and the second partition plate 26 are disposed vertically. The plane where the top plate 24 is located is parallel to the plane where the bottom plate 23 is located. By providing the horizontal bottom plate 23, it is beneficial to the placement stability of the hematology analyzer. By providing the first partition plate 25 and the second partition plate 26 perpendicular to the bottom plate 23, the first accommodation space is divided into a space layout with right-angled corners at the edges, which is beneficial to improving the space utilization rate. At the same time, other components can be fixed on the first partition plate 25 and the second partition plate 26, and the vertical setting is beneficial to ensuring the stability of the first partition plate 25 and the second partition plate 26.

[0053] In this embodiment, the specific sizes of the first space, the second space, and the third space are not limited and can be adjusted according to actual needs. Optionally, the first partition plate 25 and the second partition plate 26 are detachably disposed within the first accommodation space.

[0054] In this embodiment, the frame 20 is integrally in the shape of a rectangular frame. In other embodiments, the frame 20 can also be set in the shape of a pentahedron or other shapes.

[0055] Further, a display screen assembly is provided on the front shell 11, and the display screen assembly is connected to the front panel 21 through a hinge. By providing a hinge on the front panel 21, the display screen assembly can be rotated relative to the front shell 11 to adjust the angle of the display screen assembly, meeting the usage requirements at different angles.

[0056] As Figure 4 and Figure 5 shown, the main body further includes a reagent assembly 31 and a dye quantitative pump assembly 41. The front shell 11 and the front panel 21 enclose a second accommodation space. The reagent assembly 31 is located in the second accommodation space and fixed to the front panel 21; the dye quantitative pump assembly 41 is located on one side of the first space close to the front panel 21. The dye quantitative pump assembly 41 is used to control the quantitative suction and discharge of the fluorescent dye, and the reagent assembly 31 realizes the absorption and replacement of the fluorescent dye. By separately arranging the reagent assembly 31 and the dye quantitative pump assembly 41 on both sides of the front panel 21, the positions of the reagent assembly 31 and the dye quantitative pump assembly 41 can be made close to each other, reducing the length of the connecting pipeline and reducing the reagent usage and loss.

[0057] Specifically, the reagent assembly 31 is located in the upper right of the front panel 21, and the dye quantitative pump assembly 41 and the reagent assembly 31 are arranged opposite to each other on both sides of the front panel 21 (that is, the dye quantitative pump assembly 41 is correspondingly arranged above the front panel 21, that is, the distance from the dye quantitative pump assembly 41 to the top plate 24 is less than the distance from the dye quantitative pump assembly 41 to the bottom plate 23); the main body further includes a sampling assembly 32 for sampling. The sampling assembly 32 straddles the first accommodation space and the second accommodation space. The sampling assembly 32 is fixed to the first partition 25, and the sampling part of the sampling assembly 32 can reciprocate between the first accommodation space and the second accommodation space.

[0058] See Figure 1 , an opening 111 is provided on the front shell 11, and the opening 111 is used to replace part of the reagent assembly 31. In this embodiment, a door panel is provided on the front shell 11. After the door panel is opened, the user can take out the reagent bottle of the reagent assembly 31 from the opening 111 for replacement, and then place it back into the second accommodation space from the opening 111 after replacement. Among them, the door panel is rotatably connected to the front shell 11 to selectively close the opening 111. In other embodiments, the door panel can also be detachably connected to the front shell 11, such as snap connection. It can be understood that the specific composition and structure of the sampling assembly 32 belong to the prior art, and the sampling pipeline, sampling needle, etc. can be set with reference to the prior art, which will not be elaborated here.

[0059] A key assembly 33 is further provided in the second accommodation space. The key assembly 33 is fixed to the front panel 21, and the key assembly 33 is located at a position on the front panel 21 close to the bottom plate 23.

[0060] The main body also includes a syringe assembly 35 and a first manifold assembly 34. The syringe assembly 35 and the first manifold assembly 34 are both fixed on the front panel 21 and located in the main space. The first manifold assembly 34 is responsible for switching and opening / closing of the sampling pipeline. The syringe assembly 35 provides the sample pushing power of the blood sample for the reagent assembly 31. The first manifold assembly 34 needs to be connected to the syringe assembly 35. By fixing both the syringe assembly 35 and the first manifold assembly 34 on the front panel 21, it is beneficial to reduce the connecting pipeline between the first manifold assembly 34 and the syringe assembly 35 and reasonably control the pipeline length.

[0061] In this embodiment, both the syringe assembly 35 and the first manifold assembly 34 are fixed on the front panel 21. The syringe assembly 35 is arranged below the first manifold assembly 34, that is, the first manifold assembly 34 is embedded in the upper left of the front panel 21, and the syringe assembly 35 is embedded in the lower left of the front panel 21; the wiring parts of the syringe assembly 35 and the first manifold assembly 34 are located in the second space and the third space.

[0062] A pressure sensor assembly 36 is also provided in the second accommodation space. The pressure sensor assembly 36 is arranged on the front panel 21; the setting position of the pressure sensor assembly 36 is higher than the setting position of the syringe assembly 35. The pressure sensor assembly 36 is used to collect the liquid pressure condition in the sampling pipeline and perform real-time detection on the pressure of the sampling pipeline connected to the syringe assembly 35. When there is a pressure abnormality such as pipeline blockage, the syringe assembly 35 is stopped from operating and an alarm is given; the pressure sensor assembly 36 and the first manifold assembly 34 are arranged close to each other with a compact layout, so that the connecting pipeline between the pressure sensor assembly 36 and the first manifold assembly 34 is short. In this embodiment, the setting position of the pressure sensor assembly 36 is higher than the setting position of the first manifold assembly 34; in other embodiments, the setting position of the first manifold assembly 34 can also be set higher than the setting position of the pressure sensor assembly 36, as long as it is ensured that the setting positions of both the first manifold assembly 34 and the pressure sensor assembly 36 are higher than the setting position of the syringe assembly 35.

[0063] Such as Figure 2 and Figure 5As shown, the main machine further includes an optical component 42, which is located in the first space. Using the lost laser nucleic acid fluorescence staining detection technology, the forward scattered light, side scattered light, and side fluorescence emitted when each cell of the blood sample passes through the flow cell of the optical component 42 and is irradiated by the laser beam are collected. By uploading the above three optical signals to the whole machine signal processing system, a scatter plot of the measured blood sample is finally formed to complete the analysis and research of the sample blood cells. The optical component 42 includes a laser, a lens, a cylindrical mirror, a flow cell, a diaphragm, an optical signal receiving board, etc. The specific composition and structure of the optical component 42 belong to the prior art and can be set with reference to the prior art, so it will not be elaborated here.

[0064] In this embodiment, the frame 20 further includes an optical support frame 27, which is arranged on the first partition 25 and is located in the first space. The optical component 42 is arranged on the optical support frame 27 and is close to the top plate 24; the front plate 21 is located in front of the dye quantitative pump assembly 41, and the optical component 42 is located behind the dye quantitative pump assembly 41. By arranging the optical component 42 at a position close to the top plate 24, the optical component 42 is close to the sampling component 32, which is convenient for the blood sample to enter the optical component 42 and is also convenient for the maintenance and debugging of the optical component 42.

[0065] An impedance counting component 43 is further arranged in the first space. The impedance counting component 43 is arranged on the bottom plate 23 and is located on one side close to the front plate 21. The impedance counting component 43 is used to detect the red blood cell parameters and / or platelet parameters in the blood sample, and the impedance counting component 43 uses the impedance method to detect the parameters of particles. By arranging the impedance counting component 43 in the first space and close to the front plate 21, the liquid path connection pipeline between the impedance counting component 43 and other components can be shorter, which is beneficial to compact layout, reduces the volume of the blood analyzer, and also reduces the pipeline cost. In this embodiment, an impedance detection circuit board and a shielding cover are further arranged on the front plate 21, and the shielding cover is used to shield and protect the impedance detection circuit board; the shielding cover is a curtain made of metal or non-metal material.

[0066] A rotary door assembly 45 is also provided in the first space, and the rotary door assembly 45 is located below the optical assembly 42. A first metering pump assembly 44, an impedance tank assembly 46, and a flow valve assembly are provided on the rotary door assembly 45. The first metering pump assembly 44, the impedance tank assembly 46, and the flow valve assembly are all located in the first space. The first metering pump assembly 44 is located on the side of the rotary door assembly 45 close to the bottom plate 23, and the impedance tank assembly 46 is located on the side of the rotary door assembly 45 close to the front plate 21 and is used to provide diluent for impedance detection. By arranging the first metering pump assembly 44, the impedance tank assembly 46, and the flow valve assembly in the first space and in close proximity, the connecting pipeline between the impedance tank assembly 46 and the impedance counting assembly 43 can be made shorter, and the connecting pipeline between the impedance tank assembly 46 and the flow valve assembly can also be made shorter. It can be understood that the rotation direction of the rotary door assembly 45 can be set according to actual needs, and the rotation of the rotary door assembly 45 is realized through connection methods such as hinging.

[0067] As Figure 6 shown, an impedance counting cell assembly is also provided in the first space. The impedance counting cell assembly is arranged on the bottom plate 23 and close to the front plate 21; a swab filter assembly 47, a hemoglobin detection assembly 48, a DIFF / RET detection module 49 (blood routine examination / reticulocyte), a partial sampling assembly 32, and a syringe module 410 are also provided in the first space. The syringe module 410 is fixed on the rear plate 22, and the swab filter assembly 47, the hemoglobin detection assembly 48, and the DIFF / RET detection module 49 are arranged in sequence from the position close to the front plate 21 to the position close to the rear plate 22. The DIFF / RET detection module 49 is embedded in the first partition plate 25, and both sides of the DIFF / RET detection module 49 are exposed from the first space and the second space respectively. The second space is used to carry part of the DIFF / RET detection module 49, the partial sampling assembly 32, other liquid pipes, wires, etc. In this embodiment, a second manifold assembly 411 is also provided in the first space, and the second manifold assembly 411 is arranged at a position close to the bottom plate 23.

[0068] As Figure 7 shown, the main machine further includes a power supply assembly 51, and the power supply assembly 51 is arranged on the top of the frame 20 and located in the main space. In this embodiment, the power supply assembly 51 is arranged on the top of the second partition plate 26 and below the top plate 24, and the power supply assembly 51 is located in the second space and the third space. By arranging the optical assembly 42 in the first space and arranging the power supply assembly 51 in the main space, the influence of the electromagnetic radiation and heat dissipation of the power supply assembly 51 on the optical assembly 42 is reduced; by arranging the power supply assembly 51 at the highest position of the frame 20, the liquid in the blood analyzer will not fall on the power supply assembly 51, effectively avoiding the leakage of liquid from corroding the power supply assembly 51.

[0069] A reagent inlet is provided on the rear panel 22, and external reagents enter the hematology analyzer through the reagent inlet. A reagent preheating assembly 54 is also provided in the third space. The reagent preheating assembly 54 is arranged close to the rear panel 22 and can preheat the external reagents entering the hematology analyzer. By arranging the reagent preheating assembly 54 close to the rear panel 22, it is convenient for the external reagents to enter the reagent preheating assembly 54 after entering through the reagent inlet.

[0070] As Figure 7 and Figure 8 shown, a first reagent detection assembly 55 and a second reagent detection assembly 56 are also provided in the third space. The second reagent detection assembly 56 is used to detect the liquid path exiting from the reagent preheating assembly 54, and the first reagent detection assembly 55 is used to detect external reagents.

[0071] The first reagent detection assembly 55 includes a support plate 552 and a reagent detection module 551. The top of the reagent detection module 551 is provided with a detection liquid outlet and the bottom side is provided with a detection liquid inlet. The support plate 552 is arranged on the second partition 26. The support plate 552 is arranged at an angle with the second partition 26, and the support plate 552 extends obliquely downward in a direction away from the second partition 26. By arranging the inclined support plate 552 and setting the reagent detection module 551 on the support plate 552, with the detection liquid outlet at the top of the reagent detection module 551 and the detection liquid inlet on the bottom side, and further inclining the reagent detection module 551 on the basis that the detection liquid inlet is lower than the detection liquid outlet, it is beneficial to accelerate the discharge of air bubbles, improve the detection accuracy, and reduce the interference caused by air bubbles. Preferably, the acute angle range between the support plate 552 and the second partition 26 is 15° to 45°. In this embodiment, the acute angle between the support plate 552 and the second partition 26 is 30°.

[0072] Specifically, liquid inlet joints are provided on the bottom sides of the reagent detection module 551. The liquid inlet joints are circular tubes and the ports are the detection liquid inlets. The axis of the liquid inlet joint intersects with the plane where the second partition 26 is located at a point. By setting the axis direction of the liquid inlet joint to intersect with the plane where the second partition 26 is located at a point, the detection liquid inlet at the port of the liquid inlet joint can be inclined towards the front panel 21 or the rear panel 22, and is not directly opposite to the front panel 21 or the rear panel 22, which provides convenience for the pipeline connection at the detection liquid inlet.

[0073] In this embodiment, the first reagent detection assembly 55 includes a plurality of reagent detection modules 551 arranged side by side at intervals. The axis directions of the liquid inlet joints of the plurality of reagent detection modules 551 are parallel, and the orientations of the detection liquid inlets are the same; the liquid inlet joints are all inclined towards the rear panel 22; and the reagent detection modules of the second reagent detection assembly 56 are arranged in the same way as the reagent detection modules 551 of the first reagent detection assembly 55.

[0074] The main machine also includes a gas tank assembly 52 and an air pump assembly 53, and both the gas tank assembly 52 and the air pump assembly 53 are embedded in the second partition plate 26. The gas tank assembly 52 is used for gas storage and pressure stabilization in the gas circuit, and the air pump assembly 53 is used to provide a pressure source for the gas circuit, using compressed air as the power of the gas circuit. In this embodiment, the gas tank assembly 52 and the air pump assembly 53 are both located in the main space, and the gas tank assembly 52 and the air pump assembly 53 are both arranged across the second space and the third space.
