Definitions

  • This invention relates to the field of biomedical engineering.
  • this invention relates to a device for screening of a diabetic foot.
  • a diabetic foot is a foot that exhibits any pathology that results directly from diabetes mellitus or any long-term (or "chronic") complication of diabetes mellitus. Presence of several characteristic diabetic foot pathologies such as infection, diabetic foot ulcer and neuropathic osteoarthropathy is called diabetic foot syndrome.
  • diabetic neuropathy Due to the peripheral nerve dysfunction associated with diabetes (diabetic neuropathy), patients have a reduced ability to feel pain. This means that minor injuries may remain undiscovered for a long while. People with diabetes are also at risk of developing a diabetic foot ulcer. Research estimates that the lifetime incidence of foot ulcers within the diabetic community is around 15% and may become as high as 25%.
  • Diabetes cost a whopping USD 548 billion in health expenditure globally in 2014.
  • DFU treatment is expensive and it becomes untreatable especially if not detected at earlier stage.
  • the treatment cost for early wounds in developed countries was USD 3096 in 2010. However, if the wound becomes complicated and amputated, the cost rises to almost USD 107900.
  • Prior art diagnostic methods include checking patients sensing of touch, vibration and temperature stimuli applied to their foot sole. These tests require patients response for evaluating parameters and therefore inaccurate. Prior art devices doing these tests are discrete in nature i.e. one stimuli per device. So it takes more time - approximately 15 to 30 minutes per person for single parameter evaluation - and more human effort for single patient. Devices or Lab Tests which are non- subjective like Ankle-Brachial Index Test (ABI) or Vascular Screening are very costly and not available with many of the podiatrists and general hospitals. Also to operate these devices, skilled staff is required and generate results which only Doctors or highly trained staff can analyze. While organising camps in rural area, in addition to lack of funds and highly trained staff, portability of these devices is also a big problem.
  • An object of the invention is to provide a device focused towards early screening of diabetic patients who are susceptible to diabetic foot neuropathic ulcers.
  • Another object of the invention is to provide a device provides an objective analysis aimed towards detecting onset of diabetic foot ulcers.
  • Yet another object of the invention is to provide a device provides an objective analysis aimed towards detecting onset of diabetic foot ulcers; the objective analysis comprising a simultaneous reading of touch, vibration, and temperature of a patient’s foot.
