Title: Sphygmomanometer with vibrator producing artificial pulse - monitors propagation delay between two signals in continuous operational mode
Inventor: ENGEL ROLF DR RER NAT
IPC: A61B5/0285
Filed: 1979-06-29
Abstract: Sphygmomanometers which measure blood pressure by measuring the rate of propagation of a pulse wave in superficial arteries are limited in their accuracy by the fixed rate of the heart beat. The device employs a vibrator with a preset frequency of between 50 and 200 Hz in order to produce an artificial pulse by exerting a slight sinusoidal pressure on an artery, and time the change of blood pressure some distance away, using one or possibly two sensors. The blood pressure is measured by monitoring the propagation delay measured between the two signals produced by the two sensors. The result is very accurate and monitoring may be continuous.
