PL1 Published on October 25, 1957. ^ nap -t: LIBRARY; POLISH PEOPLE'S REPUBLIC PATENT DESCRIPTION No. 40322 Dr. med. Tomasz Cieszynski Wroclaw, Poland KI. 30 a, 4/02 Ultrasound echosounder for examining the heart The patent is valid from October 19, 1956. The subject of the invention is an ultrasonic echosounder for examining the internal structure of the heart using ultrashort sound waves. "In the echo sounder, a piezoelectric crystal is placed at the end of the catheter In the current methods of examining the inside of the heart, blood samples are usually taken from various parts of the heart with a catheter for chemical analysis, and the analysis results in possible defects of the internal structure of the heart. According to the invention, the outlines of parts of the heart of the sonar to be tested are projected onto the screen of the oscilloscope tube, which enables their direct observation and registration.
