Abstract
Изобретение относитс к медицинским приборам дл измерени тактильной чувствительности кожи. Цель - повышение точности и достоверности результатов за счет дозированной нагрузки на рецепторы достигаетс за счет того, что на державке 1, установлены с равномерным шагом дополнительные элементы раздражители 2, выполненные в виде стержней одинакового диаметра и разной длины, котора выбираетс из услови l nd/4HE/(j, где Е - модуль упругости материала стержней, d - диаметр стержней,- G - заданна торрировочна чувствительность 1 ил.This invention relates to medical devices for measuring skin tactile sensitivity. The goal is to increase the accuracy and reliability of the results due to the dosed load on the receptors due to the fact that on the holder 1, additional elements of stimuli 2 are installed with uniform pitch, made in the form of rods of the same diameter and different length, which is chosen from the condition (j, where E is the modulus of elasticity of the material of the rods, d is the diameter of the rods, - G is the specified sensitivity of 1 sm.
Description
Изобретение относитс к медицинской технике, а именно к устройствам дл измерени тактильной чувствительности кожи, слизистой оболочки зыка и губ при исследовании функции нервной системы.The invention relates to medical technology, namely, devices for measuring the tactile sensitivity of the skin, mucous membrane of the tongue and lips when studying the function of the nervous system.
Цель изобретени - повышение точности и достоверности результатов за счет дозированной нагрузки на рецепторы.The purpose of the invention is to improve the accuracy and reliability of the results due to the metered load on the receptors.
Изобретение по сн етс чертежом, на котором изображено предлагаемое устройство.The invention is illustrated in the drawing, which shows the proposed device.
Устройство состоит из державки 1, на котором с равным шагом установлены элементы раздражители 2-6, выполненные в виде стержней одинакового диаметра d и ручной длины, котора выбираетс из услови The device consists of a holder 1, on which elements of stimuli 2-6 are installed with equal pitch, made in the form of rods of the same diameter d and of manual length, which is chosen from the condition

где Е - модуль упругости материала стержней;where E is the modulus of elasticity of the material of the rods;
G - заданна торировочна чувствительность .G is the specified triaxial sensitivity.
Выбира заранее диаметр раздражителей (0,12 мм) и их длину 40, 30, 20, 15, 10 (мм), принима ,84-106 кг/см2, рассчитывают Очувст чувствительность по формуле, исход Choosing in advance the diameter of the stimuli (0.12 mm) and their length 40, 30, 20, 15, 10 (mm), taking, 84-106 kg / cm2, calculate the Ouvst sensitivity according to the formula, the outcome
из формулы Эйлера 0.„ /2.from the Euler formula 0. „/ 2.
Нагрузку на конец раздражител , начина с второго, выбирают 0,01; 0,04; 0,08; 0,1 и 0,5 г.The load on the end of the stimulus, starting with the second, choose 0.01; 0.04; 0.08; 0.1 and 0.5 g
Устройство работает следующим образом.The device works as follows.
Раздражители 2-6 устанавливают параллельно друг другу и перпендикул рно руко тке (державке) 1. Если при прикосновении раздражителем 2 и исследуемому участку кожи отсутствует реакци больного , то, отгиба раздражитель 2 производ т раздражение раздражителем 3 и продолжают до тех пор, пока не получат ответную реакцию у обследуемого. Один и тот же участок можно раздражать 5--10 с Через 5 мин можно произвести повторное исследование дл умножени полученных результатов , которое можно проводить 3-5 раз. Полученние результаты занос т в протокол исследовани .Irritants 2-6 are installed parallel to each other and perpendicular to the grip (holder) 1. If the patient reacts with irritant 2 and the examined skin, the limb irritant 2 produces irritation with irritant 3 and continues until the response of the subject. The same area can be irritated 5--10 seconds. After 5 minutes, a repeated study can be performed to multiply the obtained results, which can be carried out 3-5 times. The results obtained are recorded in the study protocol.
