2. Description of Related Art
Diabetes mellitus is a life-time chronic disease resulted from the metabolism disorder of saccharide, protein and fat in human body. The diabetes mellitus could further result in heart and kidney complications. In recent years, as observed, the morbidity of diabetes mellitus is gradually raising year by year.
Among several complications resulted from diabetes mellitus, the diabetic foot is a rather serious chronic complication. The leading factor of the diabetic foot is the lesion of the sensorimotor or the lesion of the arterial vessel. However, no matter it results from the lesion of the sensorimotor, the lesion of the arterial vessel or both of them, it'll further result in the foot necrosis due to the bad blood circulation. Even more, the patient might need to have amputation.
Regarding to the diabetes mellitus, the lesion of the sensorimotor is majorly about the symptoms of the peripheral nerve. The symptoms of the peripheral nerve would affect the peripheral sensory nerves, motor nerves and autonomic nerves. In particular, the worse of all, it might make the patient unable to feel his feet and further lose the nerves self-protection via the sensory nerves.
The loss of self-protection is a kind of negative symptom, which damages part feeling function and protecting function of nerves, which is a main reason which the patient often have foot ulcer. Clinically, the patient can't notice the disorder of the peripheral nerves. Even many patients who have already lost nerves self-protection may think that there is no problem regarding to their peripheral nerves. Thus, it is not practical to make a diagnosis about whether the patient has lost his nerves self-protection.
The most advanced vessel photograph can provide the diagnosis about the foot blood circulation, but it is costly and is an invasive process. Thus, it can't be applied in the first-line screening. Therefore, how to provide a scientific detecting device which is for the early detection of diabetic foot and is also not invasive and economical becomes a problem waiting to be solved.

The sign of the diabetic foot is found by the abnormal change of the foot temperature because of a bad blood circulation, in particular, the temperature change of the patient's instep and medial plantar. General speaking, the blood of each tissue in the human body is seriously controlled by the biological needs, and the blood source of the instep is the instep artery. For a normal person, there is less tissue around the instep (as shown in the area A in
For a diabetic foot patient, the medial plantar artery (at the inner side of the foot bottom) is often to be stuck so that the blood flow would decrease. Thus, the temperature detected at the corresponding surface of the medial plantar artery would be relatively low, which helps to diagnose the diabetic foot and also helps to prevent and suspend the ulcer.
The present invention is to provide an electric device that can detect temperatures at the medial plantar artery (hereafter as medial “plantar”) and the instep artery (hereafter as “instep”). Please refer to
