Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, and more specifically, to a blood cell analyzer. Background Technology

[0002] In modern clinical laboratories, hematology analyzers are indispensable diagnostic tools used to rapidly and accurately determine the number and types of blood cells in blood samples, including red blood cells, white blood cells, and platelets. These instruments, employing optical, electronic, or hydrodynamic technologies, provide comprehensive analysis of hematological parameters, which is of paramount importance for early disease diagnosis, treatment monitoring, and prognostic assessment.

[0003] However, traditional hematology analyzers face a key design challenge: miniaturization of the entire analyzer. To perform multiple functions, the main unit of a hematology analyzer needs to house numerous components, such as multiple reservoirs to store various liquids used in the analysis process, including diluents, cleaning solutions, and staining solutions. This results in poor space utilization of the hematology analyzer. Utility Model Content

The height of the pump body is greater than the height of the first through hole and greater than the height of the reaction cell. The second pipeline passes through the second through hole to sequentially connect the third liquid storage section, the detection section, the pump body, and the reaction cell.

[0011] Furthermore, the blood cell analyzer also includes a mounting bracket disposed inside the main housing and a gas storage unit disposed on the mounting bracket, the mounting bracket being rotatably disposed inside the main housing.

[0012] Furthermore, the blood cell analyzer also includes a mounting plate disposed inside the main housing, the main housing including a second side plate, and a mounting bracket rotatably connected to the mounting plate or the second side plate. When the mounting bracket rotates, it can switch between a position that obscures the mounting plate and a position that exposes the mounting plate.

The mounting bracket includes a mounting vertical plate and a connector. The first end of the connector is rotatably connected to the second side plate, and the mounting vertical plate is connected to the second end of the connector. The gas storage section includes multiple gas storage chambers, which are connected to both sides of the mounting vertical plate.

[0014] According to another aspect of this utility model, a blood cell analyzer is provided, comprising: a sample introduction platform for placing a sample to be analyzed; a protective housing including a main housing and a front housing connected to each other, the sample introduction platform and the front housing being disposed on the same side of the main housing, the height of the front housing being greater than the height of the sample introduction platform; a first liquid reservoir disposed within the front housing for storing a first reagent; a second liquid reservoir disposed within the front housing for storing a second reagent; and a reaction cell disposed within the main housing, the first and second liquid reservoirs being connected to the reaction cell to store the first reagent and the second reagent.

[0015] Using the technical solution of this utility model, the sample introduction platform is used to place the sample to be analyzed, so that the sample to be analyzed can be transferred to the relevant components inside the protective housing. The protective housing includes a main body shell and a front shell connected to each other, so as to provide an installation base and protection for the relevant components inside the protective housing. The sample introduction platform and the front shell are located on the same side of the main body shell. The height of the front shell is greater than the height of the sample introduction platform, so that the overall lateral dimension of the blood cell analyzer is smaller. The first liquid storage section is used to store the first reagent, and the second liquid storage section is used to store the second reagent. The reaction cell is located inside the main body shell.

On the one hand, this design frees up some installation space within the main housing. On the other hand, since the sample introduction platform already occupies some lateral space, and in related technologies, the space above the sample introduction platform is not utilized, placing the first and second liquid storage units within the front housing located above the sample introduction platform allows for full utilization of the space above the platform, thereby improving space utilization. Therefore, the technical solution of this application can effectively solve the problem of poor space utilization in related technologies. Attached Figure Description

[0027] like Figures 1 to 5 As shown, this application provides a blood cell analyzer. An embodiment of the blood cell analyzer of this application includes: a sample injection platform 10, a protective housing 20, a first liquid reservoir 30, a second liquid reservoir 40, and a reaction chamber 50. The sample injection platform 10 is used to place the sample to be analyzed. The protective housing 20 includes a main housing 21 and a front housing 22 connected to each other. The sample injection platform 10 and the front housing 22 are located on the same side of the main housing 21, and the height of the front housing 22 is greater than the height of the sample injection platform 10. The first liquid reservoir 30 is located inside the front housing 22 and is used to store a first reagent. The second liquid reservoir 40 is located inside the front housing 22 and is used to store a second reagent. The reaction chamber 50 is located inside the main housing 21, and both the first liquid reservoir 30 and the second liquid reservoir 40 are connected to the reaction chamber 50 to deliver the first and second reagents into the reaction chamber 50. In this embodiment, the first reagent is a diluent, and the second reagent is a cleaning solution; or, the first reagent is a cleaning solution, and the second reagent is a diluent; or, both the first and second reagents are diluents, in which case they can be the same or different diluents; or, both the first and second reagents are cleaning solutions, in which case they can also be the same or different cleaning solutions. In other embodiments, the first and second reagents can also be other reagents, and the user can adjust the specific categories of the first and second reagents according to the functions to be implemented.

[0028] Using the technical solution of this embodiment, the sample introduction platform 10 is used to place the sample to be analyzed, so that the sample to be analyzed can be transferred to the relevant components inside the protective housing 20. The protective housing 20 includes a main housing 21 and a front housing 22 connected to each other, so as to provide an installation base and protection for the relevant components inside the protective housing 20. The sample introduction platform 10 and the front housing 22 are located on the same side of the main housing 21. The height of the front housing 22 is greater than the height of the sample introduction platform 10, so that the overall lateral dimension of the blood cell analyzer is smaller. The first liquid storage section 30 is used to store the first reagent, and the second liquid storage section 40 is used to store the second reagent. The reaction cell 50 is located inside the main housing 21. The first liquid storage section 30 and the second liquid storage section 40 are both connected to the reaction cell 50 so as to deliver the first reagent and the second reagent to the reaction cell 50, thereby realizing the function of the blood cell analyzer in processing the sample to be analyzed. The first liquid storage section 30 and the second liquid storage section 40 are located inside the front housing 22, so that the first liquid storage section 30 and the second liquid storage section 40 can move from the main housing 21 to the front housing 22. On the one hand, this frees up some of the installation space within the main housing 21. On the other hand, since the sample injection platform 10 already occupies some of the lateral space, and in related technologies, the space above the sample injection platform 10 is not utilized, placing the first liquid storage unit 30 and the second liquid storage unit 40 within the front housing 22 located above the sample injection platform 10 can fully utilize the space above the sample injection platform 10, thereby improving space utilization. Therefore, the technical solution of this embodiment can effectively solve the problem of poor space utilization in related technologies.

[0029] like Figures 1 to 5 As shown, the main housing 21 includes a first side plate 211, which is located between the sample injection platform 10 and the reaction cell 50. The front housing 22, the first liquid storage section 30, and the second liquid storage section 40 are connected to the first side plate 211. Specifically, the first side plate 211 divides the installation space between the front housing 22 and the main housing 21, and also provides an installation base for the front housing 22, the first liquid storage section 30, and the second liquid storage section 40, so that the front housing 22, the first liquid storage section 30, and the second liquid storage section 40 can all be stably connected.

[0030] like Figures 1 to 5As shown, the blood cell analyzer also includes a first conduit. A first through-hole 212 is provided on the first side plate 211. The height of the first through-hole 212 is less than the height of the first liquid storage section 30 and the second liquid storage section 40 but greater than the height of the reaction cell 50. The first conduit passes through the first through-hole 212 to connect the first liquid storage section 30 with the reaction cell 50, and to connect the second liquid storage section 40 with the reaction cell 50. Specifically, since the first through-hole 212 is located below the first liquid storage section 30 and the second liquid storage section 40, and the first conduit passes through the first through-hole 212, the flow path from the first liquid storage section 30 to the reaction cell 50 and the flow path from the second liquid storage section 40 to the reaction cell 50 are generally extended from top to bottom. This makes the flow of the second reagent and the first reagent smoother, thereby avoiding blockage.

[0031] like Figures 1 to 5 As shown, the main housing 21 includes a first side plate 211 located between the sample introduction platform 10 and the reaction chamber 50. The hematology analyzer also includes a third liquid storage section 60 disposed within the front housing 22. The third liquid storage section 60 stores a third reagent and is connected to the reaction chamber 50. The first liquid storage section 30, the second liquid storage section 40, and the third liquid storage section 60 are distributed along the width direction of the first side plate 211. Specifically, the distribution of the first liquid storage section 30, the second liquid storage section 40, and the third liquid storage section 60 can accommodate both the lateral and height dimensions of the hematology analyzer, thus making the distribution of each liquid storage section more reasonable. Specifically, in this embodiment, the third reagent is a dye solution. In other embodiments, the third reagent can also be other reagents. Users can adjust the specific type of the third reagent according to the functions to be implemented.

[0032] like Figures 1 to 5 As shown, the hematology analyzer also includes a detection unit 70 and a pump body 80. The detection unit 70 is located inside the front housing 22, and the pump body 80 is located inside the main housing 21. The third reagent in the third reservoir 60 flows sequentially through the detection unit 70 and the pump body 80 to the reaction tank 50. Specifically, in this embodiment, the detection unit 70 is a bubble detection structure that can monitor the bubble situation in the third reagent delivery pipeline (i.e., the second pipeline mentioned later) in real time. The generation of bubbles may originate from liquid evaporation, pipeline leakage, or instability during liquid pumping. These bubbles can interfere with the normal staining and counting of blood cells, leading to inaccurate analysis results. The pump body 80 is a quantitative pump that can precisely control the delivery volume of the third reagent, ensuring that the same volume of the third reagent is used in each analysis, thereby improving the consistency and accuracy of hematology analysis. The use of the quantitative pump avoids fluctuations in analysis results caused by unstable third reagent volume and is one of the key components for achieving high-precision detection in the hematology analyzer.

[0033] like Figures 1 to 5As shown, the blood cell analyzer also includes a first pipeline and a second pipeline. A first through-hole 212 is provided on the first side plate 211, through which the first pipeline passes to connect the first liquid storage section 30 and the reaction tank 50, and to connect the second liquid storage section 40 and the reaction tank 50. A second through-hole 213 is provided on the first side plate 211, and the height of the second through-hole 213 is greater than the height of the first through-hole 212. The detection section 70 is located between the first through-hole 212 and the second through-hole 213. In the width direction of the first side plate 211, the second through-hole 213 is positioned closer to the third liquid storage section 60 relative to the first through-hole 212. The height of the pump body 80 is greater than the height of the first through-hole 212 and greater than the height of the reaction tank 50. The second pipeline passes through the second through-hole 213 to sequentially connect the third liquid storage section 60, the detection section 70, the pump body 80, and the reaction tank 50. Specifically, this arrangement minimizes the intersection of the first and second pipelines, thereby facilitating pipeline maintenance for the user.

[0034] like Figures 1 to 5 As shown, the blood cell analyzer also includes a mounting bracket 91 disposed within the main housing 21 and a gas storage unit 92 disposed on the mounting bracket 91. The mounting bracket 91 is rotatably disposed within the main housing 21. Specifically, during maintenance, the user can rotate the mounting bracket 91 to expose other components inside the mounting bracket 91, thereby facilitating maintenance of other components without having to remove or assemble the gas storage unit 92.

[0035] like Figures 1 to 5 As shown, the blood cell analyzer also includes a mounting plate 93 disposed within the main housing 21. The main housing 21 includes a second side plate 214. A mounting bracket 91 is rotatably connected to the mounting plate 93 or the second side plate 214. When the mounting bracket 91 rotates, it can switch between a position that obscures the mounting plate 93 and a position that exposes the mounting plate 93. Specifically, in this embodiment, the mounting bracket 91 is rotatably connected to the second side plate 214, allowing the mounting bracket 91 to rotate outward more easily, thereby exposing the mounting plate 93.

[0036] like Figures 1 to 5 As shown, the height of the mounting bracket 91 and the gas storage section 92 is greater than the height of the reaction tank 50. The mounting bracket 91 includes a mounting vertical plate 911 and a connector 912. The first end of the connector 912 is rotatably connected to the second side plate 214, and the mounting vertical plate 911 is connected to the second end of the connector 912. The gas storage section 92 includes multiple gas storage chambers 921, which are connected to both sides of the mounting vertical plate 911. Specifically, gas storage chambers 921 can be installed on both sides of the mounting vertical plate 911, making the layout of the gas storage chambers 921 more suitable and flexible. This allows for more efficient use of the installation space within the main housing 21.

[0037] This application also provides a blood cell analyzer, which includes a sample introduction platform 10 for placing the sample to be analyzed; a protective housing 20, including a main housing 21 and a front housing 22 connected to each other, the sample introduction platform 10 and the front housing 22 being disposed on the same side of the main housing 21, and the height of the front housing 22 being greater than the height of the sample introduction platform 10; a first liquid storage section 30 disposed within the front housing 22 for storing a first reagent; a second liquid storage section 40 disposed within the front housing 22 for storing a second reagent; and a reaction cell 50 disposed within the main housing 21, with both the first liquid storage section 30 and the second liquid storage section 40 communicating with the reaction cell 50 to deliver the first and second reagents to the reaction cell. Inside the reaction chamber 50; the main unit housing 21 includes a first side plate 211, which is located between the sample injection platform 10 and the reaction chamber 50. The front housing 22, the first liquid storage section 30, and the second liquid storage section 40 are connected to the first side plate 211. The blood cell analyzer also includes a third liquid storage section 60 disposed in the front housing 22. The third liquid storage section 60 is used to store a third reagent and is in communication with the reaction chamber 50. The first liquid storage section 30, the second liquid storage section 40, and the third liquid storage section 60 are distributed along the width direction of the first side plate 211. The blood cell analyzer also includes a mounting bracket 91 disposed in the main unit housing 21 and a gas storage section 92 disposed on the mounting bracket 91. The mounting bracket 91 is rotatably disposed in the main unit housing 21.
