If the specific posture changes, the directional indications will also change accordingly.

[0025] See Figure 1 and Figure 2 , Figure 1 This is a schematic structural diagram of the first embodiment of the POCT blood cell analyzer provided by the present application. Figure 2 yes Figure 1 A magnified view of the structure at A in the middle. Figure 1 and Figure 2As shown, the POCT blood cell analyzer of this embodiment includes a supporting seat 10 and a detection component 20.

[0026] The supporting seat 10 is used to receive the reagent kit 30, which carries the sample liquid to be tested; the detection component 20 is arranged on one side of the supporting seat 10, and is used to dock with the reagent kit 30 so that the detection component 20 can detect the sample liquid; the supporting seat 10 includes a sliding groove 110 and an upper cover 120, the sliding groove 110 is used to accommodate the reagent kit 30, the upper cover 120 is located above the sliding groove 110 and is provided with a first fastener 130, and the reagent kit 30 is provided with a second fastener 310. The reagent kit 30 moves along the extension direction of the sliding groove 110 and approaches the detection component 20, and the second fastener 310 abuts against the first fastener 130 to enable the reagent kit 30 to dock with the detection component 20.

[0027] Specifically, the POCT blood cell analyzer may further include a housing 40, which is used to shield the support base 10 and the detection assembly 20. The housing 40 is provided with an opening, through which one end of the sliding groove 110 of the support base 10 may be exposed, so that the user can push the reagent cartridge 30 containing the sample liquid into the sliding groove 110 through the opening. The detection assembly 20 is disposed on a side of the support base 10 away from the opening. When the user places the reagent kit 30 into the supporting seat 10, since the reagent kit 30 and the detection component 20 need to be docked at a certain angle, in order to improve the detection speed of the reagent kit 30, this embodiment places the reagent kit 30 in the sliding groove 110 and pushes the reagent kit 30 close to the detection component 20, so that during the pushing process, the second fastener 310 of the reagent kit 30 abuts against the first fastener 130 of the supporting seat 10, and the first fastener 130 and the second fastener 310 are engaged, so that the reagent kit 30 and the detection component 20 are docked and maintained in the current docking position, further reducing or avoiding the reverse force generated when the reagent kit 30 and the detection component 20 are docked to push out the reagent kit 30, thereby further improving the position accuracy of the reagent kit 30.

[0028] In a possible embodiment, the first fastener 130 provided on the upper cover 120 may be a snap groove, and the second fastener 310 may be, but is not limited to, a cantilever-type fastener, a ring-type fastener, a hook-type fastener, or a ball-type fastener corresponding to the snap groove; or, the first fastener 130 provided on the upper cover 120 may be a snap groove, and the second fastener 310 may be, but is not limited to, a stop or a counter-stop corresponding to the groove; or, the first fastener 130 provided on the upper cover 120 may be a snap groove, and the second fastener 310 may be, but is not limited to, components in the shape of a lug, a boss, a wedge, a claw, etc. corresponding to the snap groove, and no specific limitation is made here.

[0029] The POCT blood cell analyzer of this embodiment is used in point-of-care testing scenarios. Specifically, by reducing the number of fluidic components in the analyzer itself, and reducing the cleaning and transport processes of the fluidic components, rapid testing of the sample liquid in the reagent kit 30 is achieved to obtain test results. The POCT blood cell analyzer can be used to analyze key blood test items such as red blood cells, white blood cells, and platelets in a routine blood test to obtain test data related to relevant indicators of these key test items.

[0030] In an embodiment of the present application, the supporting base 10 of the POCT blood cell analyzer is used to receive the reagent kit 30, which carries the sample liquid to be tested; the detection component 20 is used to dock with the reagent kit 30 so that the detection component 20 can detect the sample liquid; the supporting base 10 includes a sliding groove 110 and an upper cover 120, the sliding groove 110 is used to accommodate the reagent kit 30, the upper cover 120 is located above the sliding groove 110 and is provided with a first fastener 130, and the reagent kit 30 is provided with a second fastener 310. The reagent kit 30 moves along the extension direction of the sliding groove 110 and approaches the detection component 20, and the second fastener 310 abuts against the first fastener 130 to dock the reagent kit 30 with the detection component 20. In the above manner, the POCT blood cell analyzer of this embodiment can push the reagent kit 30 located in the sliding groove 110 in the direction close to the detection component 20, and abut the second fastener 310 of the reagent kit 30 with the first fastener 130 of the upper cover 120 of the supporting seat 10, so that the reagent kit 30 is clamped in the current position of the supporting seat 10 and the reagent kit 30 is docked with the detection component 20. The docking position of the reagent kit 30 is accurate, the structure is simple and easy to implement, and the user operation is simple, which further improves the reliability of the POCT blood cell analyzer.

[0031] In one embodiment, if Figure 2 As shown, a first protrusion 320 is provided on the reagent box 30 , and the first protrusion 320 abuts against the upper cover 120 to limit the relative movement between the reagent box 30 and the supporting base 10 .

[0032] Specifically, the reagent box 30 may be provided with a plurality of accommodating cavities, which may be used to accommodate sample liquid, detection reagents related to the test items, pipette tips for the POCT blood cell analyzer to perform pipetting, etc., so that the POCT blood cell analyzer can perform operations such as pipetting and sample preparation through the reagent box 30. The first protrusion 320 is provided at one end of the reagent box 30 away from the accommodating cavity and is provided on the upper end surface of the reagent box 30. In a possible embodiment, the end of the reagent box 30 away from the accommodating cavity may be provided in the shape of a raised handle, so that the user can push the reagent box 30 in and out by means of the handle. In this case, the first protrusion 320 may be provided on the upper end surface close to the handle to abut against the upper cover 120 of the supporting base 10.

[0033] Optionally, the upper cover 120 is provided with a second recess 150, which is located on a side of the upper cover 120 near the opening of the housing 40. The second recess 150 is used to accommodate the first protrusion 320. As the reagent kit 30 moves along the extension direction of the sliding groove 110 and approaches the detection assembly 20, the first protrusion 320 gradually approaches the upper cover 120. When the second fastener 310 abuts the first fastener 130, the first protrusion 320 abuts the second recess 150 of the upper cover 120. The first protrusion 320 is used to limit the relative movement of the reagent kit 30 and the support base 10. The first protrusion 320 is located on one side of the second protrusion 330. The first protrusion 320 can be configured as an irregular arc shape. For example, the side of the first protrusion 320 close to the second protrusion 330 can be configured as a bevel having a certain abutment angle, and the second recess 150 is configured as a bevel groove corresponding to the first protrusion 320, and the angle of the bevel corresponds to the abutment angle of the first protrusion 320. In a possible embodiment, the abutment angle can range from 25° to 65°, for example, the abutment angle is 25°, 30°, 45°, 60° or 65°. By configuring the first protrusion 320 as a bevel having a certain abutment angle, the reagent kit 30 can be moved along the extension direction of the sliding groove 110 and approach the detection assembly 20. In the process, the first protrusion 320 abuts against the side wall surface of the upper cover 120 and smoothly enters the second recess 150, thereby achieving the limiting of the reagent kit 30 and the supporting seat 10.

[0034] In the embodiment of the present application, the first protrusion 320 can limit the withdrawal of the reagent kit 30 from the current docking position by abutting against the upper cover 120, and / or, when the POCT blood cell analyzer is sleeved on, withdrawn from the pipette head, or the sample tube is punctured through the pipette head, it can limit the shaking of the reagent kit 30 in the up and down directions, further improving the accuracy of the docking position of the reagent kit 30 and improving the reliability of the POCT blood cell analyzer.

[0035] In one embodiment, see Figure 3 and Figure 4 , Figure 3 This is a schematic structural diagram of the second embodiment of the POCT blood cell analyzer provided by this application. Figure 4 yes Figure 3 Schematic diagram of the structure of the kit. Figure 3 and Figure 4 As shown, a first recess 140 is provided on the side wall of the sliding groove 110 , and a second protrusion 330 is provided on the reagent box 30 . The second protrusion 330 is provided corresponding to the first recess 140 , and the first recess 140 is used to accommodate the second protrusion 330 during the movement of the reagent box 30 .

[0036] Specifically, the second protrusion 330 is disposed on the sidewall of the reagent cartridge 30, and the position of the second protrusion 330 corresponds to the position of the first recess 140. The first recess 140 is disposed on the sidewall of the sliding groove 110, and the extension direction of the first recess 140 is the same as the movement direction of the reagent cartridge 30 or the extension direction of the sliding groove 110. As the reagent cartridge 30 moves along the extension direction of the sliding groove 110 and approaches the detection assembly 20, the second protrusion 330 of the reagent cartridge 30 aligns with the first recess 140. The first recess 140 is used to accommodate the second protrusion 330 during the movement of the reagent cartridge 30, so that the reagent cartridge 30 with the corresponding second protrusion 330 can be pushed into the sliding groove 110 of the carrier 10 for detection. In which, the first recess 140 can be a first recess 140 with a certain length. When the reagent kit 30 moves along the extension direction of the sliding groove 110 and approaches the detection component 20, the second protrusion 330 slides in the first recess 140 to dock the reagent kit 30 with the detection component 20; or, the first recess 140 is arranged at the sliding tail of the reagent kit 30 in the sliding groove 110, so that when the reagent kit 30 slides along the sliding groove 110 and docks with the detection component 20, the second protrusion 330 is located in the first recess 140.

[0037] In the above manner, the POCT blood cell analyzer of this embodiment can make the supporting seat 10 correspond to the reagent kit 30 one by one by setting the first concave portion 140 and the second convex portion 330 at corresponding positions, and the supporting seat 10 can only receive the reagent kit 30 adapted thereto for detection.

[0038] Optionally, in one embodiment, the POCT blood cell analyzer includes multiple versions of the supporting base 10, and the heights of the first recess 140 of different versions of the supporting base 10 are different. Each version of the supporting base 10 is used to receive a corresponding version of the reagent kit 30, and the height of the second protrusion 330 of the corresponding version of the reagent kit 30 corresponds to the height of the first recess 140.

[0039] Specifically, the POCT hematology analyzer may include multiple versions of the carrier 10, each version of the carrier 10 having a different height of the first recess 140, each version of the carrier 10 having a corresponding reagent kit 30, and the height of the second protrusion 330 corresponding to the reagent kit 30 being equal to the height of the first recess 140, so that each version of the carrier 10 can only receive the corresponding reagent kit 30. When receiving the reagent kit 30, the carrier 10 has a receiving surface, which serves as a contact surface with the reagent kit 30 to support the reagent kit 30. The height of the first recess 140 mentioned above refers to the height between the first recess 140 and the receiving surface, and the height of the second protrusion 330 refers to the height between the second protrusion 330 and the bottom plane of the reagent kit 30, or the height of the second protrusion 330 refers to the height between the second protrusion 330 and the receiving surface when the reagent kit 30 is placed on the receiving surface.

[0040] For example, the POCT hematology analyzer may include a first version of the carrier base 10, a second version of the carrier base 10, and a third version of the carrier base 10. The height of the first recess 140 of the first version of the carrier base 10 corresponds to the height of the second protrusion 330 of the first version of the reagent cartridge 30, the height of the first recess 140 of the second version of the carrier base 10 corresponds to the height of the second protrusion 330 of the second version of the reagent cartridge 30, and the height of the first recess 140 of the third version of the carrier base 10 corresponds to the height of the second protrusion 330 of the third version of the reagent cartridge 30, so that the first version of the carrier base 10 can only receive the first version of the reagent cartridge 30, the second version of the carrier base 10 can only receive the second version of the reagent cartridge 30, and the third version of the carrier base 10 can only receive the third version of the reagent cartridge 30. It is understandable that the concave width and depth of the first recess 140 both correspond to the convex width and depth of the second protrusion 330, and the size structure of the first recess 140 and the second protrusion 330 are not specifically limited herein.

[0041] In an embodiment of the present application, the POCT blood cell analyzer can set the height of the first recess 140 of different versions of the supporting seat 10 to correspond to the height of the second protrusion 330 of the corresponding reagent kit 30, so that each version of the supporting seat 10 can only receive the corresponding version of the reagent kit 30. Therefore, the POCT blood cell analyzer of this embodiment can set corresponding versions of the supporting seat 10 and the reagent kit 30 according to different product models, sales locations, manufacturers, etc., to avoid mixing different versions.

[0042] Optionally, in another embodiment, the first recess 140 has an inclination angle on the side wall, and the POCT blood cell analyzer includes multiple versions of the supporting base 10. The inclination angles of the first recess 140 of different versions of the supporting base 10 are different. Each version of the supporting base 10 is used to receive the corresponding version of the reagent kit 30, and the inclination angle of the second protrusion 330 of the corresponding version of the reagent kit 30 is equal to the inclination angle of the first recess 140.

[0043] Specifically, the first recess 140 is an inclined groove on the sidewall of the support base 10. The POCT hematology analyzer can include multiple versions of the support base 10, each version having a different inclination angle of the first recess 140. Each version of the support base 10 has a corresponding reagent kit 30, and the inclination angle of the second protrusion 330 corresponding to the reagent kit 30 corresponds to the inclination angle of the first recess 140, so that each version of the support base 10 can only receive the corresponding reagent kit 30. When receiving the reagent kit 30, the support base 10 has a receiving surface, which serves as the contact surface with the reagent kit 30 to support the reagent kit 30. The inclination angle of the first recess 140 mentioned above refers to the relative angle between the extension direction of the first recess 140 and the receiving surface. The second protrusion 330 is a long, strip-shaped protrusion corresponding to the length and size of the first recess 140. The inclination angle of the second protrusion 330 refers to the relative angle between the extension direction of the second protrusion 330 and the receiving surface.

[0044] Exemplarily, the POCT blood cell analyzer may include a fourth version of the carrier seat 10, a fifth version of the carrier seat 10, and a sixth version of the carrier seat 10. The inclination angle of the first recess 140 of the fourth version of the carrier seat 10 corresponds to the inclination angle of the second protrusion 330 of the fourth version of the test kit 30, the inclination angle of the first recess 140 of the fifth version of the carrier seat 10 corresponds to the inclination angle of the second protrusion 330 of the fifth version of the test kit 30, and the inclination angle of the first recess 140 of the sixth version of the carrier seat 10 corresponds to the inclination angle of the second protrusion 330 of the sixth version of the test kit 30, so that the fourth version of the carrier seat 10 can only receive the fourth version of the test kit 30, the fifth version of the carrier seat 10 can only receive the fifth version of the test kit 30, and the sixth version of the carrier seat 10 can only receive the sixth version of the test kit 30.

[0045] In an embodiment of the present application, the POCT blood cell analyzer can set the inclination angle of the first recess 140 of different versions of the supporting seat 10 to correspond to the inclination angle of the second protrusion 330 of the corresponding reagent kit 30, so that each version of the supporting seat 10 can only receive the corresponding version of the reagent kit 30. Therefore, the POCT blood cell analyzer of this embodiment can set corresponding versions of the supporting seat 10 and the reagent kit 30 according to different product models, sales locations, manufacturers, etc., to avoid mixing between different versions.

[0046] In other embodiments, the POCT blood cell analyzer can also set different versions of the supporting base 10 with different settings of the first fastener 130, and the position of the second fastener 310 of the corresponding version of the test kit 30 corresponds to the position of the first fastener 130, so that each version of the supporting base 10 can only receive the corresponding version of the test kit 30.

[0047] In one embodiment, see Figure 5 , Figure 5 FIG. 1 is a schematic diagram of the structure of the third embodiment of the POCT blood cell analyzer provided by the present application. Figure 5 As shown, the test kit 30 includes a box body 350 and a skirt 351352. A detection cavity 357 is formed on the box body 350. The detection cavity 357 is used to store the sample liquid. The skirt 351352 is arranged on one side of the box body 350 and is opposite to the side wall of the detection cavity 357. The skirt 351352 is used to shield at least part of the side wall of the detection cavity 357.

[0048] Specifically, the body 350 of the test kit 30 includes a detection chamber 357 formed therein. This chamber is used to store a sample solution to be tested and allows the detection assembly 20 to detect the sample solution within the chamber 357. When the detection assembly 20 optically detects the sample solution within the chamber 357, it includes a light generator and a light receiver. The light generator emits a laser beam that passes through the body 350 and irradiates the blood cells within the sample solution, while the light receiver receives the light intensity signal generated by the irradiated blood cells. To reduce or prevent contamination of the sidewalls of the detection chamber 357 by a user touching, holding, or transferring the test kit 30, the POCT hematology analyzer of this embodiment includes a skirt 351352. The skirt 351352 shields at least a portion of the sidewalls of the detection chamber 357, allowing the user to touch the skirt 351352 to perform other operations such as handling and transferring the test kit 30.

[0049] Optionally, the detection component 20 is used to perform optical detection on the sample liquid in the detection accommodating cavity 357 . An optical detection position 352 is provided on the side wall of the box body 350 corresponding to the detection accommodating cavity 357 . The optical detection position 352 is outside the shielding area of ​​the skirt 351 352 .

[0050] Specifically, the light generator of the detection assembly 20 is used to illuminate the optical detection position 352 on the side wall of the detection accommodating cavity 357 to perform optical detection on the sample liquid. The optical detection position 352 is outside the shielding area of ​​the skirt 351352. For example, the skirt 351352 can be disposed on the side of the box body 350 near the opening of the detection accommodating cavity 357. The optical detection position 352 is disposed below the skirt 351352 and outside the shielding area of ​​the skirt 351352. This reduces or avoids contamination of the optical detection position 352 by user touch without affecting the optical detection of the detection assembly 20, thereby improving the cleanliness of the optical detection position 352, further reducing the impact of contaminated optical surfaces on the detection results of the detection assembly 20, and improving the detection accuracy of the POCT hematology analyzer.

[0051] In one embodiment, the reagent kit 30 includes a box body 350, which is formed with at least one reagent containing cavity. Scale lines are provided on the side walls of the box body 350 corresponding to the reagent containing cavity, so that the reagent volume of the reagent containing cavity can be obtained through the scale lines.

[0052] Specifically, the body 350 of the test kit 30 is formed with at least one reagent holding cavity, each of which is used to store the test reagents required by the test assembly 20. This eliminates the need for a corresponding reagent storage assembly and associated reagent fluid circuits in the POCT hematology analyzer, reducing the structural complexity of the POCT hematology analyzer. Graduation lines are provided on the sidewalls of the body 350 corresponding to the reagent holding cavities, allowing the user to easily determine the reagent volume in the cavities.

[0053] Optionally, a hemolytic agent receiving chamber 353 and a diluent receiving chamber 354 are formed on the box body 350 , a first scale line 355 is set on the side wall of the box body 350 corresponding to the hemolytic agent receiving chamber 353 , and a second scale line 356 is set on the side wall of the box body 350 corresponding to the diluent receiving chamber 354 .

[0054] Specifically, the POCT blood cell analyzer of this embodiment needs to add a hemolytic agent to the sample liquid during the detection process to destroy the red blood cell membrane in the sample liquid, causing the contents of the cell, such as hemoglobin, to be released, so that the subsequent detection component 20 can count and analyze the white blood cells, hemoglobin, DNA, RNA and other molecules in the cell. The diluent can be used to dilute the blood sample so that the detection component 20 can accurately count and measure the diluted sample. The diluent can also play a role in maintaining stability during the detection process, maintaining the conductivity in the sample liquid, maintaining cell morphology, and cleaning. In a possible embodiment, the POCT blood cell analyzer also includes a pipette component 50, which is arranged on the detection seat. The pipette component 50 is used to plug a pipette head to mix the diluent in the diluent holding chamber 354 and the hemolytic agent in the hemolytic agent holding chamber 353 with the blood sample through the pipette head to obtain the sample liquid to be tested. The first scale line 355 is used to measure the reagent volume in the hemolytic agent holding chamber 353, and the second scale line 356 is used to measure the reagent volume in the diluent holding chamber 354, so that the user can check the volume of the reagent to ensure that the reagent in the reagent kit 30 is sufficient for sample testing.

[0055] In one embodiment, the reagent kit 30 includes a box body 350 and a fixing member 360. A blood collection tube accommodating chamber 358 is formed on the box body 350. The fixing member 360 is arranged on the box body 350 and is opposite to the blood collection tube accommodating chamber 358, so that the blood collection tube can be inserted into the blood collection tube accommodating chamber 358 through the fixing member 360.

[0056] Specifically, the blood collection tube receiving chamber 358 can be used to store a blood collection tube for a small amount of blood. The fixing member 360 is provided on the box body 350 and is used to provide support for the blood collection tube, so that the blood collection tube can be inserted into the blood collection tube receiving chamber 358 through the fixing member 360. The fixing member 360 can be formed integrally with the box body 350 or can be a device mounted on the box body 350, and is not specifically limited here.

[0057] In a possible embodiment, the blood collection tube accommodating chamber 358 may include a first cavity and a second cavity that are interconnected. The fixing member 360 is disposed on a side of the box body 350 near the second cavity, so that a micro-blood blood collection tube can be inserted into the second cavity via the fixing member 360. The first cavity can be used to store whole blood blood collection tubes, so that the test kit 30 of this embodiment can accommodate micro-blood or whole blood blood collection tubes, and the blood collection tubes can be punctured and sampled using a pipette tip to prepare the sample liquid to be tested. In this manner, the POCT blood cell analyzer of this embodiment can be applied to automated processes such as micro-blood sampling, preparation, and testing, reducing user manual operations and further improving testing efficiency.

[0058] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
