Diabetic foot image processing and risk early warning equipment based on infrared thermal imaging

Abstract

The invention relates to diabetic foot image processing and risk early warning equipment based on infrared thermal imaging. The equipment comprises the following components of: an image acquisition module which generates a plurality of temperature data values and forms an infrared image of two feet by using infrared rays received by an infrared image acquisition device and emitted by the two feet; generating a color image registered with the infrared image by using a color image acquisition device; a communication module which is configured to receive the infrared and color image information acquired by the image acquisition device and input the received image into an information processing module; a man-machine interaction device which comprises input and display devices, supports a user to manually input physiological data and transmits information to the information processing module and is used for displaying basic information of a measured person,, image processing and prediction results; the information processing module which is used for performing preprocessing and feature extraction on the foot infrared image and the temperature data, importing the trained risk early warning model of the diabetic feet for analysis and prediction, and outputting a prediction result to a human-computer interaction interface for displaying the prediction result; and a power supply module.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a foot image acquisition and processing device based on thermal imaging, a diabetic foot image processing and risk warning device based on infrared thermal imaging. Background technique [0002] The "Guidelines for the Prevention and Treatment of Diabetic Foot in China (2019 Edition)" pointed out that diabetes has changed from a rare disease to an epidemic in my country, and the prevalence of diabetic foot has also increased significantly. Among diabetic patients over 50 years old in my country, the incidence of diabetic foot is as high as 8.1% %. It is estimated that a diabetic patient amputates every 20 seconds in the world; the annual mortality rate of diabetic foot ulcer patients is as high as 11%, and the mortality rate of amputee patients is as high as 22%; a review of 19 Compatible studies on the recurrence rate of ulcers showed that, About 40% of patients relapse within 1 y...

Problems solved by technology

However, when an ulcer occurs, it means that the diabetic foot has developed to a certain extent. At this time, only early warning of the risk of ulcer is not conducive to the "early screening and early prevention" of diabetic foot. early warning device

[0005] US patent "US8868157B1 Thermal optical imager system and method for detection of peripheral neuropathy" proposes a thermal optical imaging system and method for detecting peripheral neuropathy, which can be used for early warning of diabetic foot neuropathy, but this method needs to record foot immersion The temperature change curve within 15 minutes after the cold water is removed is inconvenient to operate, and the results cannot be obtained in real time. In addition, this method cannot predict the different risk levels of diabetic feet, so this method has inevitable limitations
