Sistema de monitoramento pressórico e térmico de valores anômalos no pé diabético em tempo real

Abstract

Sensitive Peripheral Neuropathy in the Diabetic Foot, resulting from Diabetes Mellitus, can cause precursor lesions of ulcers that are potential causes of lower limb amputations. The diabetic foot represents high costs in terms of hospitalization rates, chronic ulcerations and amputations, which puts a burden on the Unified Health System and also because it has a high rate of morbidity and mortality. It also affects per capita income, as this patient may be removed from work or even retired due to permanent disability, compromising their quality of life. Furthermore, the five-year mortality rate competes with most cancers. To prevent such injuries, a signaling system was designed that detects damaging pressure on the soles of the feet and issues an alarm, in addition to including temperature measurement for the initial detection of inflammation and infections in the feet. The system was designed in five phases: initial, informational, conceptual, preliminary and final design. The conceptual prototype will be produced and subjected to in-vitro tests. The aim of the system is to prevent precursor lesions, as education alone is not effective in reducing the risk of ulceration. The proposed system is economical and can be compatible with the target audience of the Unified Health System.
