Nihon University Blood Pressure Meter Doesn’t Need Any Cuff
A new type of blood pressure meter was recently outed by Nihon University. If the conventional type of such a device requires you to extend your arm to let the doctor pump an air to the integrated cuff, the one by Nihon University only need a touch of your finger. It’s not necessarily helpful, but totally cool.
Nihon University Blood Pressure meter was shown from November 14th to 17th at Medica 2012 in Dusseldorf, Germany. The reason why it was invented in the first place is that to facilitate blood pressure measurement in babies and seniors. For them, a light pressure over the upper arm can be somehow inconvenient.
Sadly, it was not very clearly laid out how the device works. The only info that was disclosed concerning in what principle it measures one’s blood pressure is “Phase Shift Method.” We’ve tried to google it but the result only returned with issues dealing with distance and 3D measurement; no blood pressure or whatsoever. If it happens that you are a relative of Prof. Sadao Omata of Nihon University, you might get the correct explanation about it for he’s the one who brings up the method.
Testees are required to place their finger tip on the provided area. A few LEDs will be lit up as the device is activated. At the same time this is taking place, photo transistors are attempting to measure the level of the blood pressure. Again, it’s rather unclear how this task is executed. By the way, the provided area where you are supposed to put your finger tip on is rather small. So, you might have issue when your physician one day decides to use it.
