A thermal imaging detection device and detection method for peripheral vascular disease

Abstract

The invention belongs to the technical field of medical instruments and particularly discloses a thermal image detection device for peripheral vascular diseases. The thermal image detection device for the peripheral vascular diseases comprises a computer, an operation table and a detection table, wherein the detection table is used for placement of a part to be detected of a person to be detected. A thermal infrared imager connected with the computer is installed on the operation table and is used for collecting infrared thermography image information of the person to be detected and transmitting the information to the computer for analysis and processing. A thermal image collecting and locating background device is arranged on the detection table. The detection device is fully combined with the infrared thermography technology, whether lesions exist in blood vessels of the person to be detected is judged through obtained infrared thermography distribution and temperature difference information for detecting the peripheral vascular diseases, and the detection device is quick in detection, free of wounds, easy to popularize, low in cost and suitable for early warning screening on the diseases for large-scale people; in addition, the detection device does not make contact with a human body in the process of detection, the detection process is free of wounds and pains and is in a non-contact mode, the detection device can be used for various simple and convenient stimulation detection methods and quick imaging, and the whole detection process is simple, quick and easy and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a peripheral vascular disease thermal image detection device and a detection method thereof. Background technique [0002] Peripheral vascular disease involves many diseases of the peripheral arterial and venous system of the human body, many of which are clinically more common diseases, such as: deep vein thrombosis (DVT), diabetes involving vascular disease (diabetic foot), arterial vasculitis obliterans; / Venous thrombosis, inflammation, varicose veins of lower extremities, superficial thrombophlebitis, common iliac vein compression syndrome, Raynaud's syndrome, etc. [0003] Conventional examination methods for such diseases include: color Doppler ultrasonography, angiography, CT and MRI examination, and skin temperature tester. Except for the color Doppler ultrasound technology and the skin temperature tester, the rest will cause different degrees of da...

AI Technical Summary

Problems solved by technology

Except for the color Doppler ultrasound technology and the skin temperature tester, the rest will cause different degrees of damage to the human body, and the inspection efficiency is low, and the inspection cost is relatively high.

[0004] Although the above-mentioned color Doppler ultrasound examination is not harmful to the human body, it has its limitations in clinical application, such as the detection of smaller arteries (such as the blood vessels below the dorsalis pedis artery and the blood vessels below the wrist artery) and tiny emboli. It is difficult to find, and it requires the operator to have a high technical level, great patience and rich clinical experience; while the skin temperature tester needs to touch the skin close to the detection site, the operation is relatively cumbersome, and the inspection process is time-consuming Longer, no visual image of the test results and low temperature resolution, so the above two methods are not suitable for large-scale crowd screening and healthy checkups
