Problems solved by technology

[0002] Sublingual microcirculation assessment can realize individualized fluid resuscitation treatment for septic shock and quickly evaluate the prognosis of patients. Other existing medical equipment cannot fully meet clinical needs
[0003] At present, the most advanced sublingual microcirculation equipment collects multiple groups of pictures under the irradiation of 530nm green light, and then analyzes the collected pictures to calculate microcirculation parameters, but it cannot achieve real-time performance; and sublingual microcirculation equipment It is bulky and not conducive to home use; in addition, the sublingual microcirculation device can only detect common microcirculation parameters, and the calculation accuracy of the microcirculation parameters is low
[0004] The reason why real-time performance cannot be achieved when calculating sublingual microcirculation parameters based on video images is that it is necessary to analyze a large number of video images to calculate the blood flow velocity and blood vessel width of each vessel, and use These parameters further calculate the morphological parameters and dynamic parameters of microcirculation, but the calculation of blood flow velocity based on video images requires a large amount of data and cannot be real-time. The accuracy of blood flow velocity is low, and external light has a greater impact on video images. Large, also greatly affects the accuracy
