Abstract
A method for monitoring pressure of blood in an artery may include contacting a non-invasive sensor of a pressure of blood monitoring device at an area above an artery of a finger, collecting with the sensor one or more pressure data readings, other than readings corresponding to an air pressure reading, from the area after the contacting and after a pressure is exerted at the area on the sensor; and analyzing with a computing device the one or more pressure data readings to generate at least one of a blood pressure reading and a heart pulse reading.
Claims21
A method for monitoring pressure of blood in an artery, comprising:
- positioning a non-invasive blood pressure (BP) monitoring device on a finger, wherein the BP monitoring device comprises a pressure sensor mounted to a brace configured to span a phalanx bone of the finger, and wherein positioning the BP monitoring device includes securing the brace to the finger using a non-stretchable strap, such that the pressure sensor of the BP monitoring device contacts an area above an artery of the finger;
- causing soft tissue of the finger to press against the pressure sensor by causing the finger to bend, such that a variable pressure is applied to the pressure sensor as a result of causing the finger to bend;
- in response to sensing, by the pressure sensor, a nonzero pressure applied to the pressure sensor as a result of the bending of the finger, sensing, using the pressure sensor in contact with the area above the artery of the finger, one or more pressure data readings, each of the one or more pressure data readings corresponding to a compression of the pressure sensor caused by blood pressure in the artery;
- and
- calculating one or both of a blood pressure value and a heart pulse rate based on an oscillometric analysis of the one or more pressure data readings by a data processing system in electronic communication with the pressure sensor.
A method of monitoring pressure of blood in an artery, comprising:
- positioning a pressure sensor of a non-invasive blood pressure (BP) monitoring device on a finger such that bending the finger causes soft tissue of the finger to press against the pressure sensor;
- in response to detection by the pressure sensor of a nonzero pressure corresponding to a compression of the pressure sensor caused by blood in the artery based on a pressure applied to the artery by bending the finger from a first position to a second position,
- sensing one or more pressure data readings each corresponding to a compression of the pressure sensor caused by blood in the artery as the finger varies the pressure applied to the artery by bending from the second position to a third position;
- and
- calculating one or both of a blood pressure value and a heart pulse rate based on an oscillometric analysis of the one or more pressure data readings by a data processing system in electronic communication with the pressure sensor.
A method of monitoring pressure of blood using a pressure sensor mounted on a finger of a patient, the method comprising:
- sensing, as the finger bends from a first position to a second position, a threshold pressure corresponding to a compression of the pressure sensor caused by blood in an artery of the finger;
- in response to sensing the threshold pressure, sensing one or more pressure data readings each corresponding to a compression of the pressure sensor by blood in the artery as the finger increases a pressure on the artery by bending from the second position to a third position;
- and
- calculating a cardiac property of the patient based on an oscillometric analysis of the one or more pressure data readings by a data processing system in electronic communication with the pressure sensor.
