The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] See also Figure 1 As shown, Figure 1 The detection component 10 of this embodiment is applied to a sample analyzer, which is a commonly used medical device for testing samples and detecting various immune indicators in the samples. For example, the sample analyzer can be a POCT blood cell analyzer.

[0032] According to some embodiments of the present application, the detection assembly 10 includes a detection member 11, a first electrode 12, and a second electrode 13. The detection member 11 can be called a detection cup, a reaction cup, or a reaction pool.

[0033] The detection element 11 has a liquid storage chamber 111 and a liquid discharge chamber 112 . The liquid storage chamber 111 is used to store the first sample to be detected. A micropore 113 is provided at the bottom of the detection element 11 . The micropore 113 is used to connect the liquid storage chamber 111 and the liquid discharge chamber 112 .

[0034] Optionally, the drainage cavity 112 is located at a side of the bottom of the detection element 11 away from the liquid storage cavity 111 , and the drainage cavity 112 is used to discharge the first sample to be detected that passes through the micropore 113 .

[0035] Optionally, the first sample to be detected may be composed of a first reagent and a first cell component test liquid, the first reagent may be a diluent, and the first cell component test liquid may be a red blood cell test liquid. In other embodiments, the first sample to be detected may be a whole blood sample or a serum sample.

[0036] Optionally, a micropore 113 is provided at the center of the bottom of the detection element 11 , and the micropore 113 is used to allow blood cells in the first sample to be detected to pass through one by one, that is, the diameter of the micropore 113 can be set accordingly according to different particle sizes of blood cells.

[0037] The first electrode 12 is disposed on the side wall 114 of the detection member 11. For example, one end of the first electrode 12 is located in the liquid storage cavity 111 of the detection member 11, and the other end of the first electrode 12 is located outside the liquid storage cavity 111 of the detection member 11, wherein the detection member 11 can be referred to as a forecell, and the first electrode 12 can be referred to as a forecell electrode.

[0038] One end of the second electrode 13 is located in the drainage cavity 112 , and the other end of the second electrode 13 is located outside the drainage cavity 112 , wherein the drainage cavity 112 may be called a back pool, and the second electrode 13 may be called a back pool electrode.

[0039] The detection component 10 is installed in a sample analyzer, and the sample analyzer draws the first sample to be detected through the drainage cavity 112, so that the blood cells in the first sample to be detected pass through the micropores 113 one by one. The sample analyzer counts the first sample to be detected through the first electrode 12 and the second electrode 13 to detect the first detection item of the first sample to be detected. For example, the first detection item includes but is not limited to the red blood cell detection item.

[0040] Optionally, the sample analyzer includes a pressure source 21 and a constant current source 22. The detection component 10 is installed on the sample analyzer. The pressure source 21 is connected to the drainage cavity 112 to provide pressure to draw the first sample to be detected through the micropores 113. For example, the pressure source 21 provides negative pressure to the drainage cavity 112. The constant current source 22 of the sample analyzer is electrically connected to the first electrode 12 and the second electrode 13 respectively. The constant current source 22 is used to provide a constant current to the first electrode 12 and the second electrode 13, so that the sample analyzer can count the first sample to be detected, and then detect the first detection item for the first sample to be detected.

[0041] The detection component 10 of this embodiment includes a detection member 11, a first electrode 12 and a second electrode 13. The detection member 11 has a liquid storage chamber 111 and a liquid discharge chamber 112. The liquid storage chamber 111 is used to store a first sample to be detected. A micropore 113 is provided at the bottom of the detection member 11. The micropore 113 is used to connect the liquid storage chamber 111 and the liquid discharge chamber 112. The detection component 10 is installed on a sample analyzer. The sample analyzer draws the first sample to be detected through the liquid discharge chamber 112, and counts the first sample to be detected through the first electrode 12 and the second electrode 13, so as to detect a first detection item for the first sample to be detected. Among them, the detection component 10 is installed on the sample analyzer. The sample analyzer detects the first detection item for the first sample to be detected through the detection member 11. The sample analyzer does not need to clean the detection member 11, which saves the cleaning system, reduces costs, and improves detection efficiency.

[0042] Optionally, after the sample analyzer completes the detection of the first sample to be detected through the detection component 10, the detection member 11 adds the second sample to be detected. The detection component 10 is installed on the sample analyzer, and the sample analyzer draws the second sample to be detected through the drainage cavity 112, so that the blood cells in the second sample to be detected pass through the micropores 113 one by one. The sample analyzer counts the second sample to be detected through the first electrode 12 and the second electrode 13 to detect the second detection item of the second sample to be detected. For example, the second detection item includes but is not limited to the red blood cell detection item.

[0043] Optionally, the second sample to be detected may be composed of a second reagent and a second cell component test liquid, the second reagent may be a diluent, and the second cell component test liquid may be a red blood cell test liquid.

[0044] In this embodiment, after the sample analyzer completes the detection of the first sample to be detected through the detection component 10, the detection component 11 is added to the second sample to be detected; the detection component 10 is installed in the sample analyzer, and the sample analyzer counts the second sample to be detected through the first electrode 12 and the second electrode 13 to detect the second detection item of the second sample to be detected. Among them, the detection component 10 is installed in the sample analyzer, and the sample analyzer detects the first detection item of the first sample to be detected through the detection component 11, and detects the second detection item of the second sample to be detected through the same detection component 11, which can realize the detection of the first detection item and the second detection item through the same detection component 11, reducing the cost of the detection component 10 and the cost of consumables. In addition, after the first detection item of the first sample to be detected is completed, there is no need to clean the detection component 11, which saves the cleaning system, further reduces the cost, and improves the detection efficiency.

[0045] Compared with other embodiments in which the micropores 113 are arranged on the side wall of the detection member 11, resulting in the inability to completely discharge the liquid in the detection member 11; the detection member 11 of this embodiment is provided with micropores 113 at the bottom, and the micropores 113 are used to connect the liquid storage chamber 111 and the liquid discharge chamber 112, so that the liquid in the liquid storage chamber 111 can be completely discharged through the liquid discharge chamber 112, thereby reducing the contamination of the first sample to be detected on the second sample to be detected, and improving the accuracy of the detection.

[0046] According to some embodiments of the present application, after the sample analyzer completes the detection of the first sample to be detected, the sample analyzer draws the first sample to be detected in the detection member 11 through the drainage cavity 112 to empty the first sample to be detected in the detection member 11 .

[0047] Since the sample analyzer has completed the detection of the first sample to be detected and there is still the first sample to be detected in the liquid storage chamber 111 of the detection member 11, the first sample to be detected remaining in the liquid storage chamber 111 will contaminate the added second sample to be detected. Therefore, after the sample analyzer has completed the detection of the first sample to be detected, the sample analyzer continues to draw the first sample to be detected in the detection member 11 through the liquid discharge chamber 112 to discharge the remaining first sample to be detected in the liquid storage chamber 111. For example, after the sample analyzer has completed the detection of the first sample to be detected, the sample analyzer controls the pressure source 21 to continue to provide negative pressure to the liquid discharge chamber 112 to draw the remaining first sample to be detected through the liquid discharge chamber 112.

[0048] In this embodiment, after the sample analyzer completes the detection of the first sample to be detected, the sample analyzer draws the first sample to be detected in the detection element 11 through the liquid discharge cavity 112 to discharge the remaining first sample to be detected in the liquid storage cavity 111, thereby preventing the remaining first sample to be detected in the liquid storage cavity 111 from contaminating the second sample to be detected, thereby improving the accuracy of the detection.

[0049] According to some embodiments of this application, please continue to refer to Figure 1 As shown, the detection member 11 includes a first shell 115 and a second shell 116, wherein the first shell 115 forms a liquid storage chamber 111, and the second shell 116 forms a liquid discharge chamber 112, wherein the first shell 115 and the second shell 116 are detachably connected. In other embodiments, the first shell 115 and the second shell 116 can be integrally formed.

[0050] The bottom of the first shell 115 is provided with a micropore 113, and the first electrode 12 is provided on the side wall of the first shell 115. The second shell 116 is located at a side of the bottom of the first shell 115 away from the liquid storage chamber 111. The second electrode 13 is provided at a side of the second shell 116 away from the micropore 113, for example, one end of the second electrode 13 is located in the liquid discharge chamber 112, the other end of the second electrode 13 is located outside the liquid discharge chamber 112, and one end of the second electrode 13 is provided opposite to the micropore 113.

[0051] The second electrode 13 of this embodiment is disposed on a side of the second shell 116 away from the micropore 113 , and one end of the second electrode 13 is disposed opposite to the micropore 113 to improve the current stability between the first electrode 12 and the second electrode 13 and improve the detection accuracy.

[0052] According to some embodiments of this application, see Figure 2 As shown, Figure 2 1 is a schematic diagram of the structure of another embodiment of the detection component of the present application. The detection component 10 of this embodiment is different from the detection component 10 disclosed in the above embodiment in that:

[0053] The second electrode 13 is disposed on one side of the second shell 116 close to the micropore 113 , for example, one end of the second electrode 13 is located in the drainage cavity 112 , and the other end of the second electrode 13 is located outside the drainage cavity 112 , and the projection of the second electrode 13 on the bottom of the first shell 115 does not overlap with the micropore 113 .

[0054] The second electrode 13 of this embodiment is arranged on one side of the second shell 116 close to the micropore 113, and the projection of the second electrode 13 on the bottom of the first shell 115 does not overlap with the micropore 113, so as to avoid the second electrode 13 blocking the first sample to be detected or the second sample to be detected passing through the micropore 113, thereby improving the detection efficiency.

[0055] Optionally, the sample analyzer further includes a light source 23 and a receiver 24. When the detection assembly 10 is installed on the sample analyzer and the detection element 11 stores the second sample to be detected, the light source 23 and the receiver 24 are respectively located on both sides of the detection element 11. The light source 23 is used to generate light so that the light irradiates the second sample to be detected in the detection element 11, and the receiver 24 is used to receive the light passing through the second sample to be detected. The sample analyzer detects the second sample to be detected by photoelectric colorimetry so that the sample analyzer detects the components of the second sample to be detected.

[0056] The sample analyzer of this embodiment includes a light source 23 and a receiver 24. The sample analyzer detects the second sample to be detected by photoelectric colorimetry, so as to detect the second sample to be detected by multiple methods, thereby improving the detection capability of the sample analyzer.

[0057] According to some embodiments of this application, see Figure 3 As shown, Figure 3 1 is a flow chart of an embodiment of the detection method of the present application. The detection method of this embodiment is applied to the detection component 10 disclosed in the above embodiment, and the detection method includes the following steps:

[0058] S301: Add a first sample to be tested into the liquid storage chamber 111 of the testing component 11, and install the testing assembly 10 on a sample analyzer.

[0059] The first sample to be detected is added to the liquid storage chamber 111 of the detection member 11, so that the liquid storage chamber 111 is used to store the first sample to be detected; the detection component 10 is installed in the sample analyzer, so that the sample analyzer detects the first sample to be detected through the detection component 10. In other embodiments, the detection member 11 can be pre-added with the first sample to be detected, and the detection component 10 is directly installed in the sample analyzer.

[0060] Optionally, the detection component 10 is installed on a detection seat of a sample analyzer, so that the sample analyzer detects the first sample to be detected in the detection component 10 .

[0061] S302 : Control the sample analyzer to draw the first sample to be detected through the liquid discharge cavity 112 , and count the first sample to be detected through the first electrode 12 and the second electrode 13 , so as to detect a first detection item for the first sample to be detected.

[0062] The pressure source 21 of the sample analyzer is connected to the drainage cavity 112 of the detection element 11 , and controls the pressure source 21 of the sample analyzer to draw the first sample to be detected through the drainage cavity 112 and the micropores 113 , so that the blood cells in the first sample to be detected pass through the micropores 113 one by one.

[0063] The constant current source 22 of the sample analyzer is electrically connected to the first electrode 12 and the second electrode 13 respectively, and the first electrode 12 and the second electrode 13 are powered by the constant current source 22 to count the first sample to be detected through the first electrode 12 and the second electrode 13 to detect the first detection item of the first sample to be detected.

[0064] In this embodiment, the sample analyzer is controlled to draw the first sample to be detected through the drainage cavity 112, and the first sample to be detected is counted through the first electrode 12 and the second electrode 13, so as to detect the first detection item of the first sample to be detected; therefore, the sample analyzer detects the first detection item of the first sample to be detected through the detection element 11, and the sample analyzer does not need to clean the detection element 11, thereby saving a cleaning system, reducing costs, and improving detection efficiency.

[0065] Optionally, after step S302, the detection method further includes:

[0066] S303: Add the second sample to be detected into the liquid storage chamber 111 of the detection element 11, control the sample analyzer to draw the second sample to be detected through the liquid discharge chamber 112, and count the second sample to be detected through the first electrode 12 and the second electrode 13 to detect the second detection item of the second sample to be detected.

[0067] After the sample analyzer completes the first test item for the first sample to be tested, the second sample to be tested is added to the liquid storage chamber 111 of the testing member 11. The pressure source 21 of the sample analyzer is connected to the liquid discharge chamber 112 of the testing member 11, and the pressure source 21 of the sample analyzer is controlled to draw the second sample to be tested through the liquid discharge chamber 112 and the micropores 113, so that the blood cells in the second sample to be tested pass through the micropores 113 one by one.

[0068] The constant current source 22 of the sample analyzer is electrically connected to the first electrode 12 and the second electrode 13 respectively, and the first electrode 12 and the second electrode 13 are powered by the constant current source 22 to count the second sample to be detected through the first electrode 12 and the second electrode 13 to detect the second detection item of the second sample to be detected.

[0069] This embodiment controls the sample analyzer to draw the first sample to be detected through the liquid discharge cavity 112, and counts the first sample to be detected through the first electrode 12 and the second electrode 13, so as to detect the first detection item of the first sample to be detected; controls the sample analyzer to draw the second sample to be detected through the liquid discharge cavity 112, and counts the second sample to be detected through the first electrode 12 and the second electrode 13, so as to detect the second detection item of the second sample to be detected. Therefore, the sample analyzer is controlled to detect the first detection item of the first sample to be detected through the detection part 11, and detects the second detection item of the second sample to be detected through the same detection part 11, so that the first detection item and the second detection item can be detected through the same detection part 11, thereby reducing the cost of the detection component 10 and the cost of consumables. In addition, after the first detection item of the first sample to be detected is detected, the second sample to be detected is directly added to the liquid storage cavity 111 of the detection part 11, without cleaning the detection part 11, saving the cleaning system, further reducing the cost, and improving the detection efficiency.

[0070] According to some embodiments of the present application, the detection method of this embodiment further includes:

[0071] In response to the sample analyzer completing the detection of the first sample to be detected, the sample analyzer is controlled to draw the first sample to be detected in the detection member 11 through the drainage cavity 112 to evacuate the first sample to be detected in the detection member 11 .

[0072] Since the sample analyzer has completed the detection of the first sample to be detected and there is still the first sample to be detected in the liquid storage chamber 111 of the detection member 11, the first sample to be detected remaining in the liquid storage chamber 111 will contaminate the added second sample to be detected. Therefore, after the sample analyzer has completed the detection of the first sample to be detected, the sample analyzer is controlled to continue to draw the first sample to be detected in the detection member 11 through the liquid discharge chamber 112 to discharge the remaining first sample to be detected in the liquid storage chamber 111. For example, after the sample analyzer has completed the detection of the first sample to be detected, the sample analyzer controls the pressure source 21 to continue to provide negative pressure to the liquid discharge chamber 112 to draw the remaining first sample to be detected through the liquid discharge chamber 112.

[0073] In response to the sample analyzer completing the detection of the first sample to be detected, this embodiment controls the sample analyzer to draw the first sample to be detected in the detection member 11 through the liquid discharge cavity 112, so as to evacuate the first sample to be detected in the detection member 11, thereby preventing the remaining first sample to be detected in the liquid storage cavity 111 from contaminating the second sample to be detected, thereby improving the accuracy of the detection.

[0074] According to some embodiments of this application, see Figure 4 As shown, Figure 4FIG. 5 is a flow chart of another embodiment of the detection method of the present application. After step S303, the detection method further includes the following steps:

[0075] S401 : controlling the light source 23 to generate light so as to irradiate the second sample to be detected in the detection element 11 .

[0076] The sample analyzer controls the light source 23 to generate light so that the light is irradiated to the second sample to be detected in the detection element 11 .

[0077] S402: Receive the light passing through the second sample to be detected by the receiver 24 to detect the components of the second sample to be detected.

[0078] The sample analyzer controls the receiver 24 to receive the light passing through the second sample to be detected, and the sample analyzer detects the second sample to be detected by photoelectric colorimetry, so that the sample analyzer detects the components of the second sample to be detected.

The detection seat is used to place the test kit of the above embodiment, the pressure source 21 is used to apply pressure to the drainage cavity 112 of the detection element 11, so that the first sample to be detected or the second sample to be detected in the detection element 11 passes through the micropore 113 of the detection element 11; the constant current source 22 is used to power the first electrode 12 and the second electrode 13 of the detection component 10.
