ABSTRACT:
A system for blood pressure measurement ascertains blood pressure indirectly by the oscillometric method at the user's index finger. Finger measurement allows the system to be smaller and easier to use than systems using conventional upper arm measurement. By using the oscillometric technique, the system according to the invention needs no microphone and so avoids the problems associated with microphone positioning. The system employs a rigid finger cuff with an inflatable inner bladder. The system extracts pulse signals transmitted via air pressure while simultaneously providing accurate pressure control.
