Introduction
Diabetes became the Asian epidemic disease
In 2025, Asia will have over
300 million diabetics at the
appointed time will burn out
the Asian medical system.

Introduction
Chronic disease: A Multisystem Disease
٥ Eye pathological change
 Soaks for a long time in
hyperglycemia‘s small-vessel.
٥ Kidney pathological change
 Every three nephritis patient
simultaneously has one person
is the diabetic.
٥ Nerve pathological change
 The nerve receives the
destruction to cause the
function damage: The foot pain,
bad to the luminance
adaptation and easy to tumble.
٥ Foot blood vessel pathological
change(PAD)
 Limps, foot ulcer and fester.

Purposes
٥ Peripheral Artery Disease(PAD)
٥ The clinical research report that over 25%
diabetic concurrent foot ulcer!
٥ Ulcer surpasses 50% are create by PAD,
defect patient almost needs to carry on treats
positively (surgical operation)
٥ PAD’s patient 50% not subjective
symptom; But after if has limps, (Second
Stage), some 20% patients need the
amputation!
٥ Earlier detection, may effectively reduce
ulcer and amputation risks.
