I know they can measure blood oxygen saturation with a finger clamp. 
(After all, blood helpfully changes colour depending on its degree of 
saturation, and human flesh is fairly transparent at optical 
wavelengths.) But I'm not aware of any such system that can do this for 
blood /pressure/ measurements.

In particular, I know a guy who has high blood pressure. The doctor has 
given him this very expensive-looking piece of automated blood pressure 
measurement equipment. Now why would anybody design such a complicated 
and expensive apparatus if a simple finger clamp could do the same job 
with a few light sensors?
