Responding to a call made by the World Health Organization (WHO), a company called Omron has created a solar powered blood pressure measuring device that can be functional even in the absence of proper power or fully trained medical personnel. The two main points are those — easy to use and operable almost anywhere. This device promises to be a blessing for health workers everywhere. The existing measures actually use no power at all but they do use mercury. So they are being phased out for environmental reasons. Also, they are relatively harder to master and read.
