Description
Изобретение относитс к протезам нреднлечь с электрическим сервонриводом , управл емым биотоками мышц, с устройством дл ощущени силы схвата.This invention relates to prosthetic devices with an electric servo-driven device controlled by muscle currents, with a device for sensing grip strength.
Предлагаемый протез позвол ет осуществл ть управление движением кисти протеза вместо механических перемещений плечевого по са или других частей тела, воздействующих на приводные т ги, применением команды в форме биопотенциалов.The proposed prosthesis makes it possible to control the movement of the prosthesis brush instead of the mechanical movements of the brachial axis or other parts of the body that act on the drive rods using a command in the form of biopotentials.
В протезе имеетс реверсивный электрический двигатель посто нно го тока, а также легкий и малогабаритный источник питани в виде аккумул торной батареи, собранной, например из серебр но-цинковых или кадмиево-никелевых элементов.In the prosthesis there is a reversible electric motor of direct current, as well as a light and compact power source in the form of a battery assembled, for example, from silver-zinc or nickel-cadmium cells.
С целью ощущени инвалидом силы сжати предмета кистью, применен вибратор, выполненный по типу костного телефона слуховых аппаратов , сигналы на который, пропорциональные силе сжати кисти, поступают из электрической цепи двигател .In order to feel a handicapped force squeezing an object with a brush, a vibrator made of a hearing aid bone phone type is used, the signals to which are proportional to the force of the brush squeeze come from the electric circuit of the engine.
На чертеже изображена схема протеза предплечь .The drawing shows a diagram of the prosthesis forearm.
Протез предплечь содержит искусственную кисть /, гильзу предплечь 2 и манжетку плеча .The prosthesis of the forearm contains an artificial brush /, the sleeve of the forearm 2 and the cuff of the shoulder.
В протезе дл сжати и разжати кисти / применен малогабаритный привод в виде реверсивного электродвигател 4 посто нного тока и редуктора 5.In the prosthesis, a compact drive in the form of a reversible direct current electric motor 4 and a gearbox 5 is used to compress and unclench the hand /.
Управление приводом осуществл етс посредством команд в форме биопотенциалов, воспринимаемых от соответствующих мыщц при их возбуждении. С этой целью применен малогабаритный электромиографиче ,ский усилитель напр жени 6 и выходной блок 7, выполненные на полупроводниковых триодах.The drive is controlled by commands in the form of biopotentials perceived from the respective muscles when they are excited. For this purpose, compact electromyographic, voltage amplifier 6 and output unit 7, made on semiconductor triodes, are used.
Дл управлени реверсом электродвигател 4 в выходном блоке применена мостикова схема соединени полупроводников. Питание усиA bridged semiconductor connection circuit is used to control the reverse of the motor 4 in the output unit. Food wuxi
