Indirect blood pressure measurement by Korotkoff sounds - Nmos type simulation

121

01:24:25

Simple blood pressure generator(green)
Cuff pressure as CR-discharge(blue)
Cuff is simulated by comparator and Nmos
Peripheral circulation is made by r+CR (orange)
2 V-V source circuits simulate the stethoscope and ear. (red)
 I made similar system with relay about 1yr ago.
Push switch and see and hear K-sounds.
