Problems solved by technology

Manual detection can only detect the plasma containing flocs or blood clots one by one, which is time-consuming and laborious; at the same time, due to the difference of the inspectors, it will inevitably bring large errors, especially for blood bags containing blood clots , the existing artificial visual inspection technology can hardly detect it, so that during blood transfusion, poor infusion or even embolism may occur
Therefore, manual detection is not only complicated, expensive, labor-intensive, inaccurate and repeatable, but also has a direct impact on people's lives, which seriously violates the development requirements of modern society for laboratory medicine.

specific Embodiment

[0036] 1. Image Acquisition

[0037] There are many means of image collection, usually a camera or a video camera can be selected, in this embodiment, an industrial high-speed camera is used to take pictures, and any plasma bag collects at least one image. It can be understood that the collected images need to be processed by a computer. The obtained image can be output to the computer in various ways, either through a memory card or through a data line. When the present invention is implemented, it can be transmitted to the computer in real time through an industrial high-speed camera data line.

[0038] 2. Image processing

[0039] In general, plasma images consist of objects, background, noise, and interference. Among them, the target is the plasma floc, and the background refers to the black area around the plasma pocket area in the image. There are several reasons for the formation of noise: (1) scratches on the wall of the plasma bag; (2) fonts and scale marks on the wa...

Abstract

The invention belongs to the field of laboratory medicine, and particularly relates to a non-destructive testing method for plasma flocs. The result of the sample to be tested is obtained by the steps of image acquisition, image processing, characteristic extraction, neural network model, comparison judgment and output and display. Compared with the traditional manual test, the method provided by the invention has high reliability and stability in testing the plasma flocs and higher speed and accuracy, and can test multiple indexes at the same time, thereby improving the production efficiency, reducing the labor intensity and lowering the test cost.

Description

technical field [0001] The invention relates to the field of laboratory medicine, uses image processing and electronic information technology to perform non-destructive detection on plasma, and in particular relates to a detection method for plasma floc. Background technique [0002] At present, the detection of blood floc in my country is almost limited to manual detection methods. Manual detection can only detect the plasma containing flocs or blood clots one by one, which is time-consuming and laborious; at the same time, due to the difference of the inspectors, it will inevitably bring large errors, especially for blood bags containing blood clots , the existing artificial visual inspection technology can hardly detect it, so that during blood transfusion, poor infusion or even embolism may occur. Therefore, manual detection is not only complicated, expensive, labor-intensive, inaccurate and repeatable, but also has a direct impact on people's lives, which seriously vio...
