The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first", "second", etc. in this application are used to distinguish between different objects and not to describe a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of a detection device of a blood analyzer according to the present application. The detection device 10 of the blood analyzer of the present embodiment includes at least one detection module 11, and the detection module 11 includes a reaction cell 12, a flow limiting pipeline 13, and a waste liquid module 14. The reaction cell 12 may be a detection cell.

The bottom of the reaction tank 12 is provided with an interface 121, and when the detection module 11 completes detection, waste liquid in the reaction tank 12 is discharged through the interface 121. The flow limiting pipeline 13 is arranged between the interface 121 and the waste liquid module 14, and the waste liquid module 14 sucks waste liquid in the reaction tank 12 through the flow limiting pipeline 13.

Before the detection module 11 completes the detection, if a pipeline in the prior art is provided between the interface 121 and the waste liquid module 14 due to the gravity of the liquid in the reaction tank 12, a portion of the liquid in the reaction tank 12 flows into the existing pipeline, so that the dilution ratio of the liquid in the reaction tank 12 changes, and the detection result of the detection module 11 is inaccurate.

In this embodiment, a flow limiting pipeline 13 is disposed between the interface 121 and the waste liquid module 14, and the pipe diameter of the flow limiting pipeline 13 is 0.5-1.2 mm. Because the liquid in the reaction tank 12 and the air in the flow limiting pipeline 13 form pressure balance, the pipe diameter of the flow limiting pipeline 13 is smaller than that of the pipeline in the prior art, the liquid in the reaction tank 12 can be reduced to flow into the flow limiting pipeline 13, the liquid amount detected in the reaction tank 12 is ensured to be stable, and the accuracy of the detection result of the detection module 11 is improved. Wherein, the pipe diameter of the flow limiting pipeline 13 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm or 1.2 mm.

In practical application, the pipe diameter of the pipeline in the prior art is large, so that the repeatability of the dilution ratio of the liquid in the reaction cell 12 is different when the detection module 11 detects each time, and the consistency and reliability of the detection result are affected. The pipe diameter of the flow-limiting pipeline 13 of the embodiment is smaller than that of the pipeline in the prior art, so that the liquid in the reaction tank 12 can be reduced to flow into the flow-limiting pipeline 13, and the consistency and reliability of the detection result are improved.

In one embodiment, the detection device 10 of the blood analyzer may include a blood routine detection module 111 and a specific protein detection module 112, as shown in fig. 2. The blood routine detection module 111 is used for performing blood routine detection on the blood sample, and the specific protein detection module 112 is used for performing specific protein detection on the blood sample. The detection module 11 of the present application may be a specific protein detection module 112, i.e. the detection apparatus 10 comprises at least one specific protein detection module 112. In other embodiments, the test device 10 may include only at least one specific protein test module.

The conventional blood test includes WBC (white blood cell) test, HGB (Hemoglobin) test, RBC (red blood cell) test, diffrential (differential white blood cell) test, or RET (reticulocyte) test. The specific protein includes one of SAA (serum amyloid A protein), CRP (C-reactive protein), TRF (transferrin ), Hs-CRP (hypersensitive C-reactive protein), PCT (procalcitonin ) and D-Dimer (D-Dimer).

Further, the detection device 10 of the blood analyzer may include a blood routine detection module 111 and a plurality of specific protein detection modules 112, for example, the plurality of specific protein detection modules 112 includes at least one CRP detection module and at least one SAA detection module, when the detection device 10 of the blood analyzer is used as an all-in-one machine of blood routine, CRP, and SAA.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a second embodiment of a detection device of the blood analyzer of the present application. The detection device 10 of the blood analyzer according to the present embodiment is described on the basis of the first embodiment, and the detection module 11 includes a controllable valve 113, and the controllable valve 113 is disposed between the interface 121 and the waste liquid module 14.

The flow limiting pipeline 13 includes a first flow limiting pipeline 131 and a second flow limiting pipeline 132, one end of the controllable valve 113 is connected to the interface 121 of the reaction tank 12 through the first flow limiting pipeline 131, and the other end of the controllable valve 113 is connected to the waste liquid module 14 through the second flow limiting pipeline 132.

When the detection module 11 detects, one end and the other end of the controllable valve 113 are disconnected, and the first flow limiting pipeline 131 is connected to the interface 121, so that the liquid in the reaction tank 12 can be reduced to flow into the first flow limiting pipeline 131, the amount of liquid detected in the reaction tank 12 is ensured to be stable, and the accuracy of the detection result is improved.

When the detection module 11 completes the detection, the waste liquid (including liquid or/and cleaning liquid) in the reaction tank 12 needs to be discharged, and one end of the controllable valve 113 is communicated with the other end, so that the interface 121 is connected to the waste liquid module 14 sequentially through the first flow limiting pipeline 131, the controllable valve 113 and the second flow limiting pipeline 132, so that the waste liquid module 14 sucks the waste liquid in the reaction tank 12 through the controllable valve 113 and the flow limiting pipeline 13.

The controllable valve can adopt a two-way valve, the two-way valve comprises one end and the other end, wherein the two-way valve realizes the communication of the two ports by a power-on and power-off mode, for example, when the two-way valve is powered on, the one end and the other end of the two-way valve are communicated, and when the two-way valve is powered off, the one end and the other end of the two-way valve are disconnected. It should be understood by those skilled in the art that if the connection mode of one end and the other end of the two-way valve is changed and the communication of the two-way valve is controlled in the opposite mode, the same effect as the above-mentioned embodiment can be achieved, and it is within the scope of the present embodiment.

The flow limiting pipeline 13 is arranged between the controllable valve 113 and the interface 121, so that the liquid in the reaction tank 12 can be reduced from flowing into the flow limiting pipeline 13, the reduction of the liquid in the reaction tank 12 is avoided, and the accuracy of the detection result is improved.

One end of the controllable valve 113 is connected to the interface 121 through the flow-limiting pipeline 13, and the other end of the controllable valve 113 is connected to the waste liquid module 14 through the first pipeline 114.

When the detection module 11 detects, one end and the other end of the controllable valve 113 are disconnected, and the flow limiting pipeline 13 is connected with the interface 121, so that the liquid in the reaction tank 12 can be reduced to flow into the flow limiting pipeline 13, the liquid amount detected in the reaction tank 12 is ensured to be stable, and the accuracy of the detection result is improved.

When the detection module 11 detects, one end and the other end of the controllable valve 113 are disconnected, and the flow limiting pipeline 13 is connected with the interface 121 through the first sub-pipeline 115, so that the liquid in the reaction tank 12 can be reduced to flow into the first sub-pipeline 115, the liquid amount detected in the reaction tank 12 is ensured to be stable, and the accuracy of the detection result is improved.

When the detection module 11 completes detection, the waste liquid in the reaction tank 12 needs to be discharged, and one end and the other end of the controllable valve 113 are communicated, so that the interface 121 is connected with the waste liquid module 14 sequentially through the first sub-pipeline 115, the flow limiting pipeline 13, the controllable valve 113 and the second sub-pipeline 116, so that the waste liquid module 14 absorbs the waste liquid in the reaction tank 12 through the second sub-pipeline 116, the controllable valve 113, the flow limiting pipeline 13 and the first sub-pipeline 115.

Referring to fig. 6, fig. 6 is a schematic structural view of a fifth embodiment of the detection device of the blood analyzer of the present application. The detection device 10 of the blood analyzer according to the present embodiment is described based on the third embodiment, and the first line 114 includes a first sub-line 115, a second sub-line 116, and a third sub-line 117.

When the detection module 11 completes detection, the waste liquid in the reaction tank 12 needs to be discharged, and one end and the other end of the controllable valve 113 are communicated, so that the interface 121 is connected with the waste liquid module 14 sequentially through the first sub-pipeline 115, the flow limiting pipeline 13, the third sub-pipeline 117, the controllable valve 113 and the second sub-pipeline 116, so that the waste liquid module 14 absorbs the waste liquid in the reaction tank 12 through the second sub-pipeline 116, the controllable valve 113, the third sub-pipeline 117, the flow limiting pipeline 13 and the first sub-pipeline 115.

Referring to fig. 7, fig. 7 is a schematic structural diagram of a sixth embodiment of a detection device of a blood analyzer according to the present application. The detection device 20 of the blood analyzer of the present embodiment includes at least one detection module 21. The detection device 20 may include a blood routine detection module and a specific protein detection module, among others. In particular, the detection module 21 may be a specific protein detection module, i.e. the detection apparatus 20 comprises at least one specific protein detection module 21, e.g. the detection module 21 is a CRP detection module. In other embodiments, the test device 20 may include only at least one specific protein test module, e.g., the test device 20 includes two CRP test modules.

The detection module 21 at least comprises a reaction cell 22, a main pipeline 25, a first cleaning module 26 and a second cleaning module 27, wherein the cleaning intensity of the first cleaning module 26 is greater than or equal to that of the second cleaning module 27.

The reaction tank 22 is provided with a first interface 222, a first end of the main pipeline 25 is connected with the first interface 222 of the reaction tank 22, the second cleaning module 27 is connected with a second end of the main pipeline 25 through a pipeline, and the first cleaning module 26 is connected between the first end and the second end of the main pipeline 25 through a pipeline.

Here, a connection position of the second cleaning module 27 and the main pipeline 25 is used as a cleaning liquid inlet B of the second cleaning module 27, and a connection position of the first cleaning module 26 and the main pipeline 25 is used as a cleaning liquid inlet a of the first cleaning module 26, so that the cleaning liquid inlet a of the first cleaning module 26 is disposed between the cleaning liquid inlet B of the second cleaning module 27 and the first interface 222 of the reaction tank 22, that is, the cleaning liquid inlet a of the first cleaning module 26 is closer to the first interface 222 than the cleaning liquid inlet B of the second cleaning module 27.

In this embodiment, the first cleaning module 26 and the second cleaning module 27 are both connected to the first interface 222 of the reaction tank 22 through the main pipeline 25, so that the number of pipelines of the detection module 21 can be reduced, and the volume of the detection module 21 can be reduced. The cleaning liquid inlet a of the first cleaning module 26 is closer to the first interface 222 than the cleaning liquid inlet B of the second cleaning module 27, so that the cleaning liquid of the first cleaning module 26 can be prevented from being diluted by the cleaning liquid of the second cleaning module 27, the concentration of the cleaning liquid of the first cleaning module 26 is ensured, and the liquid pumping accuracy of the cleaning liquid of the first cleaning module 26 is improved; furthermore, the amount of cleaning liquid used in the first cleaning module 26 can be reduced.

The first cleaning module 26 is used for injecting a first cleaning solution into the reaction tank 22 through the main pipeline 25, and the second cleaning module 27 is used for injecting a second cleaning solution into the reaction tank 22 through the main pipeline 25. Optionally, the first wash solution is a hemolytic agent, such as R1 reagent; the second cleaning solution is a diluent.

Since the cleaning liquid inlet a of the first cleaning module 26 is closer to the first interface 222 than the cleaning liquid inlet B of the second cleaning module 27, the length of the main filling pipeline 25 for the first cleaning liquid is shorter than that of the main filling pipeline 25 for the second cleaning liquid, so that the consumption of the first cleaning liquid can be reduced, and the cost can be reduced.

Specifically, when the first cleaning module 26 cleans the reaction tank 22, a cavity exists in the main pipeline 25 between the cleaning solution inlet a of the first cleaning module 26 and the first interface 222, and the first cleaning module 26 needs to fill the main pipeline 25 between the cleaning solution inlet a of the first cleaning module 26 and the first interface 222 with the first cleaning solution, so as to inject the first cleaning solution into the reaction tank 22.

In other embodiments, the main pipe 25 between the cleaning solution inlet a of the first cleaning module 26 and the first interface 222 may be filled with a second cleaning solution, and the first cleaning module 26 needs to push the second cleaning solution in the main pipe 25 into the reaction tank 22 through the first cleaning solution, wherein the cleaning solution inlet a of the first cleaning module 26 is closer to the first interface 222 than the cleaning solution inlet B of the second cleaning module 27, which can reduce the usage amount of the first cleaning solution.

When the second cleaning module 27 cleans the reaction cell 22, the second cleaning module 27 fills the main pipeline 25 with the second cleaning solution, and then injects the second cleaning solution into the reaction cell 22. Therefore, the second cleaning module 27 injects the first cleaning solution in the main pipeline 25 into the reaction tank 22 through the second cleaning solution, so as to ensure that the first cleaning solution in the main pipeline 25 is completely injected into the reaction tank 22, thereby avoiding waste and improving the utilization rate of the cleaning solution of the first cleaning module 26.

Referring to fig. 8, fig. 8 is a schematic structural view of a seventh embodiment of a detection device of a blood analyzer according to the present application. The detection apparatus 20 of the blood analyzer of this embodiment is described on the basis of the sixth embodiment, and the detection module 21 of this embodiment includes a blending module 28, and the blending module 28 is connected to the second end of the main pipeline 25 through a pipeline for blending the liquid in the reaction cell 22.

When the amount of the first cleaning solution used in the first cleaning module 26 is relatively small, the amount of the first cleaning solution in the reaction tank 22 is relatively small, so that the speed of cleaning the inner wall of the reaction tank 22 by the blending module 28 through the first cleaning solution is low. Wherein mixing module 28 passes through the second end of tube coupling main line 25, and second cleaning module 27 can pour into the second washing liquid into reaction tank 22 this moment into, and mixing module 28 pours into the second washing liquid in the main line 25 into reaction tank 22 to drive the first washing liquid in the reaction tank 22 through the second washing liquid and carry out the mixing washing, with the effect and the abluent speed of the mixing that improve reaction tank 22.

In other embodiments, the position of the blending module 28 is farther from the first interface 222 than the cleaning solution inlet B of the second cleaning module 27, so as to facilitate the blending module 28 to blend the liquid in the reaction tank 22.

In an embodiment, the detection module 21 comprises a first controllable valve 261 and a second controllable valve 271, the first washing module 26 is connected to one end of the first controllable valve 261 by a pipeline, and the other end of the first controllable valve 261 is connected between the first end and the second end of the main pipeline 25 by a pipeline, i.e. the other end of the first controllable valve 261 is connected to the washing liquid inlet a of the first washing module 26 by a pipeline. The second cleaning module 27 is connected with one end of a second controllable valve 271 through a pipeline, and the other end of the second controllable valve 271 is connected with the second end of the main pipeline 25 through a pipeline, i.e. the other end of the second controllable valve 271 is connected with the cleaning liquid inlet B of the second cleaning module 27 through a pipeline.

When the first cleaning module 26 cleans the reaction tank 22, one end and the other end of the first controllable valve 261 are communicated, so that the first cleaning module 26 is communicated with the first controllable valve 261, the main pipeline 25 and the first interface 222 in sequence. At this time, one end and the other end of the second controllable valve 271 may be disconnected.

When the second cleaning module 27 cleans the reaction tank 22, one end and the other end of the second controllable valve 271 are communicated, so that the second cleaning module 27 is sequentially communicated with the second controllable valve 271, the main pipeline 25 and the first interface 222. At this time, one end and the other end of the first controllable valve 261 may be disconnected.

Referring to fig. 9, fig. 9 is a schematic structural view of an eighth embodiment of a detection device of a blood analyzer according to the present application. The detection device 20 of the blood analyzer of the present embodiment is described on the basis of the seventh embodiment, and the detection module 21 of the present embodiment includes the first heating module 291.

When the reaction cell 22 is cleaned by the first cleaning solution and/or the second cleaning solution, the first heating module 291 is used for heating the first cleaning solution and/or the second cleaning solution, so as to prevent the temperature of the reaction cell 22 from being affected by the temperature of the first cleaning solution and/or the second cleaning solution being low, shorten the time for the temperature of the reaction cell 22 to be restored to the preset temperature, and improve the detection efficiency.

In one embodiment, the detection module 21 includes a second heating module 292, a reagent module 29, and a third controllable valve 293, the reagent module 29 is connected to one end of the third controllable valve 293 by a pipeline, the other end of the third controllable valve 293 is connected to the second heating module 292 by a pipeline, and the second heating module 292 is connected to the second interface 223 of the reaction cell 22.

The second heating module 292 is configured to heat the reagent of the reagent module 29, that is, when the reagent module 29 injects the reagent into the reaction cell 22, the second heating module 292 is configured to heat the reagent injected into the reaction cell 22, so as to avoid the temperature of the reagent from being affected by the low temperature of the reagent, shorten the time for the temperature of the reaction cell 22 to return to the preset temperature, and improve the detection efficiency.
