Abstract

A pulse analyzing apparatus includes a measuring unit, a capture unit for processing a pulse signal from the measuring unit, and an operation analyzing unit for calculating the pulse signal processed by the capture unit. Thus, the pulse analyzing apparatus uses a multi-way measurement process to simultaneously measure the pulse signals of different portions of a tested person, thereby simplifying the measurement process and saving the time.

Claims

a measuring unit including a first measuring member mounted on a first portion of a tested person to measure a first pulse signal information of the first portion of the tested person and a second measuring member mounted on a second portion of the tested person to measure a second pulse signal information of the second portion of the tested person, a time differential being defined between the first pulse signal information and the second pulse signal information, and a conducting distance being defined between the first portion and the second portion of the tested person;

a capture unit connected to the measuring unit to capture the first pulse signal information measured by the first measuring member of the measuring unit and the second pulse signal information measured by the second measuring member of the measuring unit simultaneously; and

an operation analyzing unit connected to the capture unit to standardize the first pulse signal information and the second pulse signal information and to perform an operation on the time differential and the conducting distance to calculate a pulse wave velocity of the tested person.

2. The pulse analyzing apparatus in accordance with claim 1, wherein the first measuring member of the measuring unit measures the first pulse signal information by emitting and receiving an optical signal passing through the first portion of the tested person, and the second measuring member of the measuring unit measures the second pulse signal information by emitting and receiving an optical signal passing through the second portion of the tested person.

3. The pulse analyzing apparatus in accordance with claim 1, wherein the first portion and the second portion of the tested person are located at the same side of the tested person.

4. The pulse analyzing apparatus in accordance with claim 3, wherein the first portion of the tested person is one finger of the tested person, and the second portion of the tested person is one toe of the tested person at the same side.

5. The pulse analyzing apparatus in accordance with claim 4, wherein the conducting distance is defined as a difference between a vertical distance of the finger of the tested person to the carotid artery and a vertical distance of the toe of the tested person to the carotid artery.

6. The pulse analyzing apparatus in accordance with claim 1, wherein the capture unit includes a first processing module to provide a filtering, gain and digital processing work to the first pulse signal information and the second pulse signal information.

7. The pulse analyzing apparatus in accordance with claim 1, wherein the operation analyzing unit includes a second processing module to locate wave crests, wave troughs and starting points of the first pulse signal information and the second pulse signal information and to calculate a heart rate and the pulse wave velocity of the tested person.

8. A pulse analyzing apparatus for analyzing a first pulse signal information and a second pulse signal information obtained from a first portion and a second portion of a tested person respectively, a time differential being defined between the first pulse signal information and the second pulse signal information, and a conducting distance being defined between the first portion and the second portion of the tested person, the pulse analyzing apparatus comprising:
