Problems solved by technology

However, the above-mentioned method of directly intercepting the image of the reaction area of ​​a fixed size in the microtube for analysis is only applicable to a certain size of the microcolumn gel card. When the width of the microcolumn gel card used is different, the intercepted reaction area It is not comprehensive, or the interception area is too large, which may affect the final analysis results and cause misjudgment.

Embodiment 1

[0041] Such as figure 1 As shown, it is a flow chart of the microcolumn gel card agglutination detection result identification method of the present invention, and the method includes the following steps:

[0042] (1) Collect images, collect images of micro-column gel cards that have undergone agglutination and centrifugation;

[0043] (2) Intercepting the microtube image in the microcolumn gel card image;

[0044] (3) Obtain the target area to be identified in the microtubules image, the target area is the image area within the microtube inner wall;

[0045] (4) In the above-mentioned target domain, capture the effective reactant area, and identify the position and relative area of ​​the captured effective reactant area;

[0046] (5) Judging and outputting the agglutination detection result of the microtubules according to the preset standards of reactant position and relative area.

[0047] Such as Figure 4 As shown, the method for intercepting the microtubules image in...

Embodiment 2

[0055] On the basis of Example 1, the effective reactant area is captured and identified from the above-mentioned target area, and the judgment and identification is carried out according to the preset standard. The effective reactant area appears on the image as the bright area A and the sub-bright area B in the above target area image, such as image 3 , 7 and 8 are shown. In the step (4), the effective reactant region is captured, and the method for identifying the position and relative area of ​​the captured effective reactant region comprises the following steps: B1, searching for a bright region, and identifying the position of the bright region in the microtube; B2, finding For the sub-bright area, the position and relative size of the sub-bright area in the microtubules are identified. Among them, the bright area is the image area where the gray value in the target area is greater than or equal to the first threshold, that is, the area where red blood cells in the mi...

Embodiment 3

[0075] Such as Figure 9 In the shown embodiment 3, on the basis of the embodiment 1 or 2, a step of result confirmation is added, and the agglutination detection result output above is manually confirmed to complete the identification of the agglutination detection result of the microtubules. For example, after the result is judged, the judgment result is output in the form of a pop-up window or other forms, and manual confirmation of the result is required, and the system ends the recognition work only after confirmation. After manual confirmation, misjudgment due to instrument failure or other reasons is avoided.

Abstract

The invention relates to the technical field of medical instruments, and discloses a method for identifying the agglutination detection result of a micro-column gel card. The method comprises the following steps: acquiring the image of the micro-column gel card, intercepting a micro-tube image, acquiring a target area, capturing and identifying an effective reactant area, and judging and outputting the obtained identification result. A micro-tube inner wall boundary line is automatically fitted through binary processing, and the obtained reaction area within the micro-tube inner wall boundary line is used as an analysis target area, so the interference of the image part beyond the area to analysis and judgment is avoided, the identification accuracy is effectively improved, the method is suitable for identifying the agglutination detection results of micro-column gel cards having various different specifications, and the versatility of the method in analysis systems having different specifications is improved; and brightness position and relative area combination classified judgment of the effective reactant area in the analyzed target area is carried out, and contrast analysis of rough classification and detailed classification is carried out, sot eh result identification accuracy is further improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a method for identifying agglutination detection results of a microcolumn gel card. Background technique [0002] At present, clinical blood testing generally adopts the cassette detection method with simple operation, clear results and stability. To control the size of the gel gap, so that the gap can only allow free red blood cells to pass through, so that free red blood cells and aggregated red blood cells are separated. The detection principle is: when the antigen and antibody react, the blood cells agglutinate, and when centrifuged, the agglutination cannot pass through the gap of the gel, but stays in the upper layer of the gel tube, and the reaction is positive. Unagglutinated blood cells can pass through the gel gap during centrifugation and settle at the bottom of the gel tube, giving a negative reaction. [0003] In an automated blood analyzer, the judgment of t...
