Abstract
The invention determines the heart rate and respiration rate of a patient through the patient's extremities. Heart rate and respiration rate are determined via an energy spectrum, periodogram or histogram using a time series analysis. A patient can stand near the device and lean on it, or stand on a piezoelectric pad. A microcomputer provides calculations to determine heart and respiratory rates using signal processing and time series analysis of data.
Claims23
A heart rate and respiration rate monitoring method comprising:
- providing at least one piezoelectric pad,
- providing one or more surfaces on the at least one piezoelectric pad for contacting a patient's feet or hand extremities with the piezoelectric pad,
- providing one or more discretized sensor arrays on the one or more surfaces of the piezoelectric pad,
- contacting the patient's feet or hand extremities to the one or more discretized sensor arrays by leaning on or standing on and thereby contacting the one or more discretized sensor arrays,
- collecting discretized acoustic, electromechanical or other physiological signals with the discretized sensing array,
- converting the discretized acoustic, electromechanical or other physiological signals into discretized voltage signals,
- transmitting the discretized voltage signals from the discretized sensing array to a receiving and computing device,
- calculating a value for the heart rate and respiration rate of a patient via analyzing time series data and producing energy spectra for each location that the patient's feet or hand extremities contact the discretized sensor array.

A heart rate and respiration rate monitoring device comprising:
- one piezoelectric pad having a size to receive feet or hands of a patient,
- a surface of the one piezoelectric pad for contacting the patient's extremities,
- a discretized sensing array grid on a surface of the piezoelectric pad for collecting discretized acoustic, electromechanical or other physiological signals and
