Existing detection technologies (such as infrared thermal imaging and plantar pressure analyzers) have the following problems:

[0003] The equipment is expensive and requires professional personnel, making it difficult to popularize in primary healthcare institutions or homes;

[0004] The operation is complicated and cannot meet the daily self-examination needs of patients;

[0005] Its large size makes portable monitoring impossible.

[0006] Therefore, there is an urgent need for a low-cost, easy-to-operate, and home-use self-examination device for diabetic foot. Utility Model Content

[0009] Preferably, the control switch includes a first control switch and a second control switch, wherein the first control switch independently turns the infrared temperature sensor on and off, and the second control switch independently turns the photoelectric sensor and the pressure sensor on and off.

[0010] Preferably, the pressure sensor is a MEMS micro-sensor, and the display screen is a micro OLED display screen.

[0011] The advantages of this utility model are:

[0012] 1. Low cost and easy to popularize: It adopts miniature sensors and integrated design, resulting in low production costs and making it suitable for large-scale promotion; moreover, its compact structure makes it easy to carry.

[0013] 2. Easy to operate: Patients can independently perform self-testing of foot temperature, pulse and blood flow without professional guidance;

[0014] 3. Long charging cycle and service life: Built-in independent first and second control switches control the instantaneous temperature acquisition and the blood flow and pulse pressure monitoring that require long-term monitoring separately, so as to achieve independent start and stop, save energy, and thus extend the charging cycle and service life of this probe.

[0015] 4. Precise fit: The banana-shaped shell and elastic band design adapt to different foot shapes, improving measurement accuracy. Attached Figure Description
