Abstract

FIELD: medicine. SUBSTANCE: invention is meant for registration of excessive or difference of pressures in medical devices, for instance for registration of pressures of inhalation and expiration of patient in medical devices, for diagnostics and treatment of diseases of breathing organs and in some other branches of economy. Essence of invention lies in protection of sensitive element from effects of environment, in prevention of influence of hand touching on parameters of tensoconverter, in provision for measurement of small values of pressure with high metrological characteristics of tensoconverter. EFFECT: increased stability of operation of tensoconverter during long time operation, expanded application field, enhanced accuracy of measurement of small values of pressure. 1 dwg

Использование: для регистрации избыточного или разности давлений в приборах медицинской техники, например, для регистрации давлений вдоха и выдоха пациента в медицинских приборах, для диагностики или лечения заболеваний органов дыхания, а также в других областях народного хозяйства. Цель: повышение стабильности работы преобразователя при его длительной работе и расширение области применения. Сущность: защита чувствительного элемента от влияния окружающей среды, исключение влияния эффекта касания руками на параметры тензопреобразователя, обеспечение измерения малых величин давления при высоких метрологических характеристиках тензопреобразователя. Положительный эффект: высокая точность измерения малых величин давления. 1 ил.Usage: for recording excess or differential pressure in devices of medical equipment, for example, for registering the inspiratory and expiratory pressure of a patient in medical devices, for the diagnosis or treatment of respiratory diseases, as well as in other areas of the national economy. Purpose: increasing the stability of the converter during its long operation and expanding the scope. Essence: protecting the sensitive element from environmental influences, eliminating the influence of the touch effect by hands on the strain gauge parameters, ensuring the measurement of small pressure values at high metrological characteristics of the strain gauge. Positive effect: high accuracy of measurement of small pressure values. 1 ill.
