Research on Intelligent Fingertip Blood Collection Robot

ABSTRACT

At present, fingertip blood sampling is mainly done manually by medical workers. Under the COVID-19 epidemic, medical workers are easily infected, in addition, the finger needs to be squeezed to increase the amount of bleeding during the blood collection process, which will cause the cell fluid to enter the blood and cause the test results to be inaccurate. This paper presents a kind of design about an intelligent fingertip blood sampling robot. We get the finger vein image through the near-infrared imaging module, and select the vein intersection area as the blood collection point after image segmentation, which will be helpful in improving the amount of bleeding. We use the laser to guide the end of the blood collection robot puncture needle and blood collection vessels to achieve rapid and accurate blood puncture and blood collection operation. The experimental results show that the maximum deviation between the blood sampling needle and the blood sampling point does not exceed 0.15mm and the longest time from fingertip blood sampling point selection to guide the blood sampling needle to the blood sampling point is less than 9.8 seconds. © 2021 ACM.
