Document Type and Number:
Japanese Patent JP2006095329
Kind Code:
A
Abstract:
To realize a low-power consumption device for estimating the blood flow rate in a blood vessel.
This device for repeatedly estimating a blood flow rate over a certain period of time includes: one or more transducers; and an electric excitation signal source applied to at least one of one or more transducers during an active period enough to obtain a blood flow rate estimated value, and removed from at least one of one or more transducers during the idle period until the next blood flow rate estimated value is obtained.
