Abstract
An aspect of the disclosure pertains to finger blood pressure cuff. The finger blood pressure cuff may include a housing having an opening sized to receive a human finger and an inflatable elastic bladder disposed about an inward-facing surface of the opening. The inflatable elastic bladder may be inflated to pressurize a user's finger and temporarily occlude blood flow in the user's finger. The finger blood pressure cuff may include a pressure sensor for obtaining blood pressure measurements.
Claims20
A device for estimating a user's blood pressure, the device comprising:
- a housing having a hole sized to receive a human finger;
- a pump;
- an inflatable elastic bladder disposed about an inward-facing surface of the hole and defining, at least in part, a pressurizable volume in fluidic communication with the pump, wherein the pump is configured to pressurize the pressurizable volume and cause the inflatable elastic bladder to expand towards the center of the hole and contact a user's finger when the user's finger is positioned in the opening of the device and the pump is activated;
- and
- a pressure sensor in fluidic communication with the pressurizable volume and configured to produce pressure data indicative of a pressure within the pressurizable volume as a function of time.
