The invention discloses a device for detection a
cerebral blood flow regulation function, which belongs to the technical field of
biomedical engineering. The device comprises a piezoelectric
ceramic plate (1), a fixed elastic ribbon (2) of the piezoelectric
ceramic plate (1), a trans-cranial
Doppler probe module (3), a detection box (5), a light-emitting
diode (6) and a
phase difference result display LED (7), wherein the piezoelectric
ceramic plate (1) is used for measuring pulse
waves; the trans-cranial
Doppler probe module (3) is used for measuring medium-sized
artery blood flow velocity
waves; the light-emitting
diode (6) is arranged on the detection box (5) and is used for indicating effective characteristic
waves; and the piezoelectric ceramic plate (1) and the trans-cranial
Doppler probe module (3) synchronously measure signals and are connected with a
respiratory frequency band characteristic wave extraction and
phase difference detection circuit arranged in the detection box (5) through a connecting wire (4) respectively. The device needs no external
artery blood pressure control, has high use safety, uses the piezoelectric ceramic plate to measure pulse pulsation
signal waveforms from a
wrist directly, and evaluates the
cerebral blood flow regulation function according to phase changes of
respiration characteristic waves of pulse and the
cerebral blood flow, and has the advantages of use safety, simple and convenient operation, quick measuring and
processing speed and high performance
price ratio.
