Title: Ultrasonic heart diagnosis equipment - has electronic frequency filter to limit ultrasonic Doppler shift signal
Inventor: MOSLER KARL-HEINZ PROF DR MED
IPC: A61B8/02
Filed: 1974-12-13
Abstract: Individual physiological events during a heart action are registered using ultra sonic equipment whereby the ultrasonic Doppler shift signal is limited by electronic frequency signals so that rapid movements, esp. the heart valves closing produce temporally well defined and easily triggered signals. Pref. the time interval between two trigger impulses can be measured and continuously registered. The signal produced coincides with a physiological, anatomical movement in the heart and can be compared with other signals i.e. the R peaks of an ECG. With this device intra-uterine foetal heart action can be detected and measured from the 12th week of pregnancy.
