Abstract

A blood pressure monitor equipped with a cardiovascular health condition monitoring module includes: a blood pressure measurement device measuring a user'"'"'s blood pressure signal; a host including a blood pressure monitor microprocessor that processes blood pressure correlated signal; a control panel equipped to the host and configured to control blood pressure measured by the blood pressure monitor and heart rhythm analysis; a first display device displaying blood pressure result; and a second display device displaying heart rhythm analysis from the cardiovascular health condition monitoring module.

Claims

1. A blood pressure monitor coordinated with a cardiovascular health condition monitoring module, comprising:

a blood pressure measurement device that measures and outputs a user'"'"'s blood pressure signal;

a cardiovascular health condition monitoring module comprising a light source device and an optical sensor, wherein the cardiovascular health condition monitoring module detects a heartbeat interval signal of the user, obtains a heart rhythm signal by the heartbeat interval signal, and outputs the heart rhythm signal of the user;

a host coupled with the blood pressure measurement device and the cardiovascular health condition monitoring module, the host equipped with a microprocessor that processes the user'"'"'s blood pressure signal and the user'"'"'s heart rhythm signal, and that acquires a waveform of a heart rhythm measurement result from the user'"'"'s heart rhythm signal;

a control panel deposited at one side of the host and configured to couple with and control the blood pressure measurement device and the cardiovascular health condition monitoring module; and

a first display device deposited next to the side with the control panel and coupled to the microprocessor to display whether the waveform of the heart rhythm measurement result is an atrial fibrillation signal,

wherein the processing of the user'"'"'s blood pressure signal and the user'"'"'s heart rhythm signal by the host comprises;

a first filtration stage comprising calculating an average of all heartbeat intervals, a standard deviation of all the heartbeat intervals, and differences between two consecutive heartbeat intervals according to the heartbeat interval signal to determine whether there is the atrial fibrillation signal; and

a second filtration stage comprising excluding abnormal heartbeat signals by determining the differences between the two consecutive heartbeat intervals and a median of all the heartbeat intervals so as to determine whether there is the atrial fibrillation signal, when the first filtration stage is not able to determine whether there is the atrial fibrillation signal.

2. The blood pressure monitor coordinated with the cardiovascular health condition monitoring module of claim 1, further comprising:

a second display device,

wherein the microprocessor acquires a waveform of a blood pressure measurement result from the user'"'"'s blood pressure signal, and

wherein the second display device displays the waveform of the blood pressure measurement result.

3. The blood pressure monitor coordinated with the cardiovascular health condition monitoring module of claim 1, wherein the waveform of the heart rhythm measurement result of the cardiovascular health condition monitoring module is a PhotoPlethysmoGraphy (PPG) waveform.

4. The blood pressure monitor coordinated with the cardiovascular health condition monitoring module of claim 1, wherein the cardiovascular health condition monitoring module monitors heartbeats by using a transmittance measurement to detect and output the user'"'"'s heart rhythm signal.

5. The blood pressure monitor coordinated with the cardiovascular health condition monitoring module of claim 1, wherein the processing of the user'"'"'s blood pressure signal and the user'"'"'s heart rhythm signal by the host further comprises:

a third filtration stage comprising calculating a standard deviation of remaining heartbeat intervals, the remaining heartbeat intervals being the heartbeat intervals that remain after the abnormal heartbeat signals are excluded during the second filtration stage, and determining whether there is the atrial fibrillation signal by comparing the standard deviation of the remaining heartbeat intervals with a third abnormal filtration database, when the second filtration stage is not able to determine whether there is the atrial fibrillation signal,

wherein the third abnormal filtration database uses judgment rules comprising average of normal heart rate, average heart rate, standard deviation of heart rate, and distribution and ratio about difference between two consecutive heart rates.
