Description
II
Изобретение относитс к медишшской технике и может быть использовано в диагаостических цел х.The invention relates to Medish technique and can be used for diagastic purposes.
Известно устройство дл исследовани параметров дыхани , содержащее термочувствительный датчик, усилитель и ре- гистратор, соединенные последовательноA device for studying respiration parameters is known, which contains a temperature-sensitive sensor, an amplifier and a recorder connected in series.
ИОдаако известное устройство имеет низкую чувствительность и большую инерционность .IODAAKO known device has a low sensitivity and high inertia.
Целью изобретени вл етс повышение чувствительности и &з1стродействи устройства ДЛЯ исследовани параметров дыхани ..,5The aim of the invention is to increase the sensitivity and effect of the device for the study of respiratory parameters .., 5
Дл достижени поставленной цели в .пр)едлагаемом устройсгее, содержащем термочувствительный, датчик, усилитель и регистратор, соединенные последовательно , термочувствительный датчик вьтолнен jg в виле аолого с отверсти ми в ториах усеченного коиуса из пол ризованногс csrнетоэлектрического материала, с внешней и внутренней сторон которого расположены электроды, покрытые слоем изол ционного материала и соединенные с усил№телем .To achieve this goal in the proposed device containing a temperature-sensitive sensor, amplifier and recorder, connected in series, the temperature sensor is filled jg in the shaft with openings in the torii of the truncated coi from polarized non-electroelectric material, with the outer and inner sides of the torus. electrodes covered with a layer of insulating material and connected to the amplifier.
На чертенке изображена принципиальна схема устройства дл исследовани параметров дыхани .The imp is a schematic diagram of the device for the study of respiratory parameters.
Устройство содержит термочувствительный датчик 1, вьшолненный в виде полого с отверсти ми в торцах усеченного конуса из пол ризованного сегнетоэлектр№ческого материала, с внешней и внутренней сторон которого распол-ожены электроды 2, покрытые слоем 3 изол ционного материала и соединенные через усилитель 4 с регистратором 5.The device contains a temperature-sensitive sensor 1, made in the form of a hollow with holes in the ends of a truncated cone made of a polarized ferroelectric material with electrodes 2 on the outer and inner sides, covered with a layer 3 of insulating material and connected through the amplifier 4 to the recorder five.
Устройство ДЛЯ регистрации параметрров дыхани работает, следующим образом.The device for registering breathing parameters works as follows.
Под вли нием вдыхаемого и выдыхаемого потоков воздуха вследствие пироэффекта между электродами 2 возникает электрический ток. Величина тока регистрируетс регистратором 5.Under the influence of the inhaled and exhaled air flows, due to the pyroelectric effect between the electrodes 2 an electric current occurs. The current value is recorded by the recorder 5.
