Description
Technical field
Medical treatment detection device field is the utility model is related to, is to be related to a kind of hand-held physioneurosis in particular
Become automatic detection equipment.
Background technology
Autonomic neuropathy is due to that the autonomic nerve fibers for dominating heart and blood vessel impaired cause Rate control and blood vessel
Power abnormality, it is the lesion of diabetic complication earliest period.Epidemiology survey shows there is diabetic autonomic neuropathy
5 years fatal rates of patient be 5 times of non-diabetic autonomic neuropathy.But it is recessive rise that autonomic neuropathy,diabetic, which becomes mostly,
Disease, patient start often no conscious sympton, treat that its clinical symptoms occurs, irreversible pathological change has occurred in autonomic nerve.
If it can be found relevant with diabetic autonomic neuropathy by the early diagnosis of diabetic autonomic neuropathy
Silent myocardial ischemia, the possibility of heart infarction and sudden cardiac death, diabetic autonomic neuropathy is obtained early stage, effective
Complex treatment, so that it may reduce the generation of these relevant diseases of diabetic autonomic neuropathy.But lack at present conveniently, it is sensitive
Detect the means of autonomic neuropathy.
The most frequently used method for being used to diagnose peripheral neuropathy now is Semmes-Weinstein methods.Such as ability
Known in domain, Semmes-Weinstein monofilament includes the nylon filament being embedded in plastic handle, by using bending
The physical attribute of column (buckling column) with generate in theory independently of apply to the handle power power, the Buddhist nun
Imperial filament is used to semi-quantitatively evaluate the threshold sensitivity for touching and touching.Actually be transferred to the actual pressure of skin surface with
Angle between filament and skin and change.In addition, do not consider the friction between filament and skin in the measurements, but the friction
It may change among individual significantly, so as to which constant error is introduced in these measurements.More importantly, Semmes-
Weinstein monofilament tests the approximate range that can estimate sensitivity, rather than the individual particular sensitivity.Alternative method
2 Static touch are applied to skin surface.This two separated touch point of test measurement, which will be left, how far makes the two
Touch point perceived as two completely different points.The tip of the test equipment is by two parallel, adjustable pins of its spacing
Acanthopore forms.Similar Semmes-Weinstein is tested, 2 points of tests by the orientation of acanthopore Relative Skin influenceed and by
To the influence to be rubbed between equipment and skin.Similarly, the threshold of feelings is depended on by scrutineer on the tissue area checked
The intensity of pressure applied.
Another method using calibrated tuning fork or vibration perception threshold meter (biothesiometer,
biothesiometer).Increase is attached to the amount of the vibration of the vibrating tip of skin until the patient feels to vibration.Vibration perception
Threshold value is measured with volt.The subject matter of biothesiometer equipment is that they generate ripple rather than local thorn
Swash.Vibration wave is propagated on the relatively large region of skin and hypodermis, so that the nerve of its extremely difficult identification most serious
The position (needing to protect the tissue of the opening position) of lesion.
