Abstract
The present invention relates to a blood pressure monitor for non-invasive blood pressure measurement comprising a blood pressure sensor for measuring peripheral arterial pressure and a heart reference unit that comprises a first fluid column, with a first end positionable at blood pressure sensor level, and a second fluid column, with a first end positionable at a reference level, preferably the heart level, and at least one heart reference sensor for sensing the pressure prevailing in the first fluid column and the second fluid column. The invention further relates to a heart reference unit for a blood pressure monitor according to the invention.
Claims18
A blood pressure monitor for blood pressure measurement, the blood pressure monitor comprising:
- a blood pressure sensor configured to measure a peripheral arterial pressure;
- and
- a heart reference unit, the heart reference unit comprising:
- a first fluid column with a first end positionable at a level of the blood pressure sensor,
- a second fluid column with a first end positionable at a reference level, and
- at least one heart reference sensor configured to sense pressures prevailing in the first fluid column and the second fluid column,
- wherein a second end of the first fluid column and a second end of the second fluid column, each at an end of its respective fluid column opposite the corresponding first end of each said fluid column, are configured for positioning at a predetermined elevation relative to each other.
A heart reference unit for use with a blood pressure monitor including a blood pressure sensor, the heart reference unit comprising:
- a first fluid column with a first end positionable at a level of the blood pressure sensor,
- a second fluid column with a first end positionable at a reference level, and
- at least one heart reference sensor configured to sense pressures prevailing in the first fluid column and the second fluid column,
- wherein a second end of the first fluid column and a second end of the second fluid column, each at an end of its respective fluid column opposite the corresponding first end of each said fluid column, are configured for positioning at a predetermined elevation relative to each other.
