"Medical examinations are very important for disease prevention." Joseph glanced at the entrance of the medical examination center and said to his wife, "We'd better have a comprehensive check-up every six months in the future."
"Hmm, I'll follow your advice."
The two walked into the examination center amidst a group of bowing nobles, and Joseph immediately saw a glass tube as thick as an arm and almost as tall as an adult standing in the center of the hall.
The nursing home's director, Jean-Noel Haler, eagerly introduced, "Your Highness, the instrument ahead is the sphygmomanometer, which uses the pressure of concentrated saline in the glass tube to compress the artery. Then the water level is gradually reduced until the pulse starts beating again. At that point, the water pressure is the human blood pressure..."
Doctor Bisha behind him hurriedly whispered, "Director, did you forget? This device was invented by the Regent King himself."
