[0047] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0048] Please refer to the attached Figure 1 - Attachment Figure 4 The embodiment of the present invention provides an efficient blood sampling detection device, comprising:
[0049] Intelligent sample identification module: Based on image recognition technology, the sample label image is obtained through the camera, and the blurred, stained or partially missing labels are extracted and repaired to obtain blood sample information;
[0050] Fully automatic sample loading system: used to automatically load blood samples by controlling the robotic arm;

[0052] Micro-pipette assembly: It is installed on the robotic arm and uses a micro-pipette equipped with a disposable pipette tip to add blood samples;
[0053] Anti-cross-contamination device: used to set up positive pressure airflow barriers and air filtration devices to isolate each blood sample;
[0054] Intelligent detection module: Based on fluorescent labeling detection technology, the sampled blood is tested, analyzed and managed.
[0055] Specifically, the intelligent sample recognition module uses a camera to obtain sample label images, and extracts and repairs blurred, stained or partially missing labels to obtain blood sample information, avoid sample confusion due to label problems, greatly improve the accuracy and efficiency of sample processing, provide a reliable sample information basis for subsequent testing processes, reduce possible errors in manual identification, and ensure that testing work is carried out in an orderly manner from the source;
[0056] The fully automatic loading system controls the robotic arm to automatically load blood samples, which can replace manual loading operations and realize the automation of the loading process, so that multiple loading operations can be performed simultaneously. The control of the robotic arm can ensure the consistency and accuracy of loading, reduce the loading errors caused by human factors, and improve the stability and reliability of the entire detection process.
[0057] The adaptive sample volume control module uses sensors to obtain the concentration and density of each sample before sampling, and then automatically adjusts the sample volume, so as to determine the most appropriate sample volume according to the actual characteristics of the sample, avoiding the impact of too much or too little sample on the test results, effectively improving the accuracy of the test results, making the test data more scientific and reliable, adapting to the test needs of different samples, and improving the quality of the test work;
[0058] By binding the micro-volume sample addition component to the robotic arm, micro-volume and precise sample addition of blood samples can be achieved. The disposable pipette tip effectively prevents cross-contamination between samples, and ultimately achieves precise control of sample addition volume to meet the test items with strict requirements on sample volume. At the same time, it ensures the safety of the test process and avoids deviations in test results due to cross-contamination.
[0059] Through the anti-cross-contamination device, a positive pressure airflow barrier and an air filter are set up to isolate each blood sample, build a relatively independent and clean testing environment, prevent cross-contamination between different blood samples due to aerosol transmission, air pollutants and other factors, create a safe and reliable environment for testing, and ensure the authenticity and reliability of each sample test result;
[0060] Through the intelligent detection module, the added blood is tested, analyzed and managed based on the fluorescent labeling detection technology, so that the target substances in the blood samples can be detected quickly and accurately.

[0065] Specifically, the sample label image obtained by the image text recognition unit is grayscaled, and the color image is converted into a grayscale mode that is easy to process. At the same time, the noise reduction algorithm is used to remove the interference noise in the image to make the image clearer. Then, the text in the image is divided into single characters through character segmentation to prepare for subsequent recognition. Finally, the character features are extracted and recognized using a deep convolutional neural network model, and the text information on the sample label is converted into data that the computer can understand. This overcomes the problems of low efficiency and error-proneness of traditional manual recognition, improves the speed and accuracy of sample information extraction, and provides a reliable data foundation for subsequent sample processing processes.
