Description

Technical Field

[0001] The invention relates to the field of blood type detection, and particularly to a full-automatic blood type analyzer and a control system thereof. Background Art

[0002] Blood type test paper is a portable tool for rapid blood type detection. You only need to add a small amount of blood sample to the test paper, wait for a while, and then determine the blood type by observing whether an agglutination reaction occurs. It is widely used in preliminary blood type determination in medical emergency, blood type screening at blood donation sites, and self-blood type testing at home.

[0003] Blood type test strips are based on the principle of antigen-antibody reaction for blood type detection. They contain antibodies that can react specifically with blood type antigens. For example, the test strips for detecting ABO blood types contain anti-A antibodies and anti-B antibodies. When the blood sample is dropped on the test strip, the antibodies in the test strip will interact with the antigens on the surface of red blood cells. If the blood is type A, the A antigen on the red blood cells will combine with the anti-A antibodies on the test strip to produce agglutination. If it is type B, the B antigen on the red blood cells will combine with the anti-B antibodies to produce agglutination. Type AB blood will show agglutination in both areas, while type O blood will not show agglutination in either the anti-A or anti-B antibody areas.

[0004] However, the existing method of testing blood type by blood type test paper has some shortcomings: 1. The existing method does not detect the blood type test paper before testing the blood type, and does not check whether the blood type test paper has quality problems. Due to factors such as user operating errors or poor production quality, the blood type test paper may have quality problems such as damage, dirt or wrinkles. If the blood type test paper with quality problems is not discovered and continues to be used, the blood type measurement results will be inaccurate.

[0005] 2. The existing methods lack monitoring of the blood sampling process. The quality of blood samples directly affects the accuracy of the test results. If the blood collection time is too long, it may cause blood coagulation, affecting the diffusion of blood on the test paper, resulting in insufficient number of red blood cells in the test area, which may cause false negative results in blood type test. At the same time, long-term blood collection may also cause blood contamination, interfering with the normal antigen-antibody reaction of blood type detection, thereby causing deviations in test results.

[0006] 3. The existing methods do not take into account the possible impact of the test environment such as temperature, humidity and light intensity on the blood type measurement results. A poor test environment will interfere with the normal antigen-antibody reaction of blood type detection and affect the stability of red blood cells in blood samples and reagents in test strips, thereby reducing the accuracy and reliability of blood type detection results. Summary of the invention

If the outline of the blood type test paper in the blood type test paper monitoring image completely overlaps with the outline of the blood type test paper in the blood type test paper standard image, then the blood type test paper is not damaged; otherwise, the blood type test paper is damaged.

[0075] The time taken by the fully automatic blood type analyzer to collect the blood sample is compared with the preset warning value of the time for collecting the blood sample. If the time taken by the fully automatic blood type analyzer to collect the blood sample is greater than the preset warning value of the time for collecting the blood sample, the quality of the blood sample does not meet the standard, and the blood type test paper is further replaced to collect the blood sample again.

[0076] In this embodiment, the present invention obtains the time used to collect the blood sample to evaluate whether the quality of the blood sample meets the standard, and further replaces the blood type test paper to re-collect the blood sample, thereby avoiding the use of unqualified blood samples for blood type testing, thereby ensuring the accuracy of the blood type test results.

In a specific embodiment, the weights corresponding to the influencing factors of the test environment temperature, humidity and light intensity are 0.35, 0.35 and 0.3 respectively.

[0088] The influence coefficient of the test environment on the measurement result is compared with the preset influence coefficient threshold. If the influence coefficient of the test environment on the measurement result is greater than the preset influence coefficient threshold, the test environment is poor, an early warning is issued, and a prompt is given through the display screen of the fully automatic blood type analyzer.

[0089] In this embodiment, the present invention collects the temperature, humidity and light intensity of the test environment of the fully automatic blood type analyzer, analyzes the influence coefficient of the test environment on the measurement results, determines whether the test environment is suboptimal, and issues early warnings and prompts, thereby ensuring the normal progress of the antigen-antibody reaction in blood type detection and the stability of the red blood cells in the blood sample and the reagents in the test paper, thereby improving the accuracy and reliability of the blood type detection results.
