Description
Изобретение относитс к медицине, а именно к пищеводным зондам и элект родам дл исследовани сердца.This invention relates to medicine, namely to esophageal probes and electrodes for examining the heart.
Цель изобретени - повьшение точности установки и фиксации рабочей части зонда по данным пищеводной электрокардиограммы.The purpose of the invention is to increase the accuracy of the installation and fixation of the working part of the probe according to the esophageal electrocardiogram.
На чертеже изображено устройство дл исследовани де тельности сердцаThe drawing shows a device for examining the activity of the heart.
Устройство содержит полый зонд 1 с закрытым концом, выполненный из диэлектрического материала, баллон 2 из эластичного материала, герметично установленный на поверхности зонда в рабочей части, отверсти 3 в боковых стенках зонда, расположенные внутри баллона, кольцевые электроды 4, трубку 5 стетоскопа, камеру 6, мембрану 7 стетоскопа, кран 8 и штуцер 9 дл подключени источника 10 повьшенного давлени .The device contains a hollow probe 1 with a closed end, made of a dielectric material, a cylinder 2 of elastic material, hermetically mounted on the surface of the probe in the working part, holes 3 in the side walls of the probe, located inside the cylinder, ring electrodes 4, stethoscope tube 5, chamber 6 , a membrane 7 of the stethoscope, a valve 8 and a fitting 9 for connecting a source 10 of increased pressure.
Устройство используют следующим образом.The device is used as follows.
Рабочую часть зонда 1 ввод т в пищевод через нос или рот, как и при обычном зондировании желудка на глубину 32-36 см. Выводы электродов 4 подключают к электрокардиографу и, наблюда за формой кардиограммы,The working part of probe 1 is introduced into the esophagus through the nose or mouth, as in the usual sensing of the stomach to a depth of 32-36 cm. The conclusions of the electrodes 4 are connected to an electrocardiograph and, watching the shape of the ECG,
устанавливают устройство так, чтобы с помощью кольцеобразных электродов 4 регистрировалась пищеводна электрокардиограмма с наиболее высокой ам- п,питудой биопотенциалов, левого .предсерди и желудочков. С помощью источника 10 повышенного давлени , например шприца, надувают баллон 2, а кран закрывают. При этом стенки баллона 2 воспринимают шумы и тоны сердца, которые передаютс в камеру 6 и на мембрану 7 стетоскопа.The device is installed so that using the ring-shaped electrodes 4, the esophageal electrocardiogram is recorded with the highest ampli tude, the power of the biopotentials, the left atrium and the ventricles. The balloon 2 is inflated with a pressure source 10, such as a syringe, and the valve is closed. In this case, the walls of the balloon 2 perceive the noises and tones of the heart, which are transmitted to the chamber 6 and to the membrane 7 of the stethoscope.
