Description

Diabetic shoe system for plantar pressure monitoring and decompression in diabetic patients

technical field

The invention relates to data monitoring technology of diabetic patients, in particular to a diabetic shoe system used for monitoring and decompression of diabetic plantar pressure.

Background technique

Diabetes has become a major public health problem. Diabetes has many complications, including diabetic neuropathy. Diabetic neuropathy damages the nerves of nearly 50% of diabetic patients, is the main cause of diabetic foot syndrome, has a high incidence rate, reduces the quality of life of patients, and requires high medical care costs. Foot ulcers are a major complication in diabetic patients, with 15-25% of diabetic patients developing foot ulcers during their lifetime. Peripheral neuropathy is a common underlying cause of foot ulcers in diabetics because the lack of painful feedback allows unwanted repetitive tissue damage to occur. Elevated plantar pressure is associated with diabetic foot ulcers. Therefore, it is highly desirable for patients to add artificial sensory pressure devices to signal to protect the foot in the event of abnormally high plantar pressure. Measuring plantar pressure is a very effective way of determining your risk of developing foot ulcers.

A pair of smart shoes could fill this need by providing long-term monitoring and stress-relief features for diabetics. Diabetic plantar pressure can be measured while wearing these smart shoes. Studying the distribution of plantar pressure in high-risk diabetic patients and observing the impact of other key abnormalities on the development of ulcers in long-term wearing smart shoes, the findings will be very valuable for patients who avoid damage to their feet and improve their quality of life.
