Abstract
A blood pressure measuring device includes a flexible element configured to at least partially surround a body part and having a stiffening element configured to stiffen the flexible element; and at least one pressure sensor element attached to the flexible element.
Claims24
A blood pressure measuring device comprising:
- a single air-tight pouch having a connection tube, the air-tight pouch functioning as a flexible element configured to at least partially surround a body part;
- a stiffening element disposed in the air-tight pouch and configured to stiffen the flexible element by evacuating air contained in the air-tight pouch;
- at least one pressure sensor element having a sensor cable attached to an inside surface of the flexible element that is to be pressed against the body part such that, during use, the at least one pressure sensor element will contact the body part;
- and
- a control device configured to control the stiffening element by controlling the level of vacuum in the air-tight pouch.

A method for measuring the blood pressure of a living being, the method comprising:
- using a blood pressure measuring device comprising:
- a single air-tight pouch having a connection tube, the air-tight pouch functioning as a flexible element configured to at least partially surround a body part;
- a stiffening element disposed in the air-tight pouch and configured to stiffen the flexible element by evacuating air contained in the air-tight pouch;
- at least one pressure sensor element having a sensor cable attached to an inside surface of the flexible element that is to be pressed against the body part such that, during use, the at least one pressure sensor element will contact the body part;
- and
- a control device configured to control the stiffening element by controlling the level of vacuum in the air-tight pouch,
- placing the flexible element with the blood pressure sensor element onto a body part to be measured such that the flexible element assumes a shape adapted to the body part;
- changing the flexible element to the stiffened state in the assumed shape;
- measuring the pressure signal over a certain period of time while the flexible element is in the stiffened state;
- and
- returning the flexible element to a non-stiffened state.
