Abstract
A sensor for blood-based measurement parameters that can be integrated on any flat surface to allow for ubiquitous monitoring of hemodynamics is disclosed. Such a sensor can measure heart rate, heart rate variability, blood pressure, etc. The sensor is adapted to be placed in direct contact with blood vessels. This can be done with an accelerometer or another type of vibrational or acoustic sensor in order to measure arterial vibrations.
Claims20
A device for measuring blood-related parameters, said device comprising:
- a sensor module adapted to measure vibrational or acoustic signals from a patient's blood flow;
- a data-acquisition unit, communicatively coupled to said sensor module, and adapted to digitize said vibrational or acoustic signals;
- a memory unit, communicatively coupled to said data-acquisition unit, and adapted to buffer and save said digitized vibrational or acoustic signals;
- and
- a data-processing unit, communicatively coupled to said memory unit, and adapted to convert said digitized vibrational or acoustic signals into one or more measured parameters.
