TODAY’S PATENT- DEVICES AND METHODS FOR CONTROLLING INFLATION RATE IN BLOOD PRESSURE MEASUREMENTS

Devices and methods for controlling inflation rate in blood pressure measurements device was invented by the inventors namely Dan Stefan Tudose (Bucharest), Xi Zhang (San Francisco, CA), Keith Adam Wong (San Francisco, CA), Andrew Larsen Axley (Mountain View, CA), Peter W. Richards (San Francisco, CA), Conor Joseph Heneghan (Campbell, CA), Radu Dobroiu (Bucharest), Alexandru-Mihai Ş olot (Braşov); patented by the USPTO on January 17, 2023, bearing patent number US11553848B2. This patent has been assigned to FITBIT, INC. (San Francisco, CA).

A portion of the disclosure deals with techniques for managing the inflation rate during a blood pressure measurement as well as a blood pressure measuring apparatus. A pressurizable volume of the blood pressure measuring apparatus is defined, at least in part, by its inflatable bladder. It is possible to inflate the inflatable bladder to pressurise the user’s appendage and momentarily stop the blood supply to it. The blood pressure measurement device has a pressure sensor that measures blood pressure and a pump that inflates the inflatable bladder and regulates the inflation rate by varying at least one of the drive frequency, duty cycle, or voltage.

The present disclosure relates to a blood pressure cuff that is wrapped around a user’s finger. The term “finger blood pressure cuff” in this context refers to any system, gadget, or apparatus that fits around a user’s finger and is designed to take the user’s blood pressure.
