Problems solved by technology

If you want to achieve accurate results, you can only rely on the test time being long enough, but this is unrealistic in actual clinical practice, especially when the test needs to be completed by applying different DC voltages

Embodiment Construction

[0016] The detailed description provided below in conjunction with the accompanying drawings is intended as a description of the examples of the invention, rather than representing the only form for explaining or utilizing the examples of the invention.

[0017] Autonomic neuropathy is a multifactorial disease, of which diabetes is the main cause. Autonomic neuropathy due to diabetes can lead to dysfunction of the sweat glands, especially in the distal extremities. The dysfunction of sweat glands leads to fibrosis of sweat gland tissue, blockage of sweat ducts, reduction of subcutaneous sweat, and thickening of the cuticle. At the same time, the ion concentration and pH value of sweat will become abnormal. The ion concentration and pH factor of sweat play a major role when measuring the electrochemical properties of the skin. Therefore, it is possible to judge the pathological changes of the autonomic nerves of diabetes by testing the electrochemical properties of sweat, and...

Abstract

The invention relates to a non-invasive detection system and method for automatic neuropathy. The non-invasive detection system comprises an electrode array, a voltage reference module, a switch array, a measuring module, an adjustable resistor, a discrete voltage module, a central processing unit, an analysis module and the like. The method comprises the steps of using the adjustable precision resistor for achieving human body resistance changes and an equivalent resistance of a capacitance effect after a human body resistance and the equivalent resistance of the capacitance effect; then, determining an access to be tested; after voltages of two poles of an electrode and the voltage of the adjustable precision resistor in a circuit are tested and stored, processing data to generate I-U curve charts so as to obtain a group of slope data; and performing automatic neuropathy feature analysis through comparison of a pathology database according to the slope data to obtain the pathology condition to which a subject belongs, and outputting results.

Description

technical field [0001] The invention relates to medical equipment, and mainly relates to a non-invasive detection system and a detection method for autonomic neuropathy. Background technique [0002] Autonomic neuropathy is the abnormality of heart rate control and vascular dynamics due to damage to the autonomic nerve fibers innervating the heart and blood vessels. It is the earliest lesion of diabetic complications. Epidemiological surveys show that the 5-year mortality rate of patients with diabetic autonomic neuropathy is 5 times that of patients without diabetic autonomic neuropathy. However, diabetic autonomic neuropathy is mostly a recessive onset, and patients often have no symptoms at the beginning. When the clinical symptoms appear, irreversible pathological changes of autonomic nerves have appeared. [0003] If the possibility of painless myocardial ischemia, myocardial infarction and sudden cardiac death related to diabetic autonomic neuropathy can be found thro...
