Background technique

Diabetes is a group of metabolic diseases characterized by hyperglycemia. At present, the incidence of diabetes in the world is as high as 8.35%, and about 382 million people suffer from diabetes. The long-term high blood sugar in diabetes will lead to chronic damage and dysfunction of various tissues in the human body, especially the eyes, kidneys, heart, blood vessels, and nerves, and lead to various complications. Diabetic foot disease is a serious complication of diabetes. Amputation patients due to diabetic foot disease account for 1/3 of the total number of amputations. Studies have shown that if early plantar screening is carried out for diabetic patients, and corresponding treatment is carried out for patients Foot protection education and therapeutic interventions can reduce the likelihood of amputations by 85%. Due to nerve and blood vessel damage in the lower limbs of diabetic patients, the plantar pressure will increase significantly. The increased plantar pressure increases the patient's risk of plantar ulcers, and the increased foot pressure can be used as a risk factor for diabetic patients with plantar ulcers.

As shown in Figures 1-4, the utility model provides a plantar pressure monitoring device, including:

A pressure monitoring unit, which includes a microcontroller, an acceleration sensor connected to the microcontroller through a line, a memory, and a communication transmission module, the communication transmission module is connected to the mobile terminal through a signal, and the communication transmission module is set to Bluetooth The transmission module, the mobile terminal adopts a mobile phone or a tablet computer, and the microcontroller stores the received data in the memory, and the stored user's plantar pressure monitoring data is sent to the mobile terminal through the communication transmission module by the memory;

The pressure detection unit includes several pressure sensors 07 attached to the upper surface of the insole 02, and the pressure sensors 07 are distributed at the sole 021 and the forefoot 022 of the insole 02 at a density of 4 pieces/cm ² .
