Abstract

This invention discloses a heart rate measuring device and a method for measuring heart rate thereof. The heart rate measuring device can be put on a user body. The heart rate measuring device includes a first electrode, a second electrode, a plurality of optical indicating units, a signal processing circuit and a control unit. When the user'"'"'s both hands touch the first electrode and the second electrode, the control unit provides a heart signal by using the first electrode, the second electrode and the signal processing circuit. The control unit controls the optical indicating units to output electrocardiographic signals.

Claims

1. A heart rate measuring device, worn by a subject, comprising:

a first electrode;

a second electrode;

a plurality of optical indicating units;

a signal processing circuit, coupled to the first electrode and the second electrode; and

a control unit, coupled to the signal processing circuit and the optical indicating units, wherein when the first electrode and the second electrode are both in contact with the subject, the control unit provides electrocardiographic signals by using the first electrode, the second electrode and the signal processing circuit, the control unit further controlling the optical indicating units to output electrocardiographic signals.

2. The heart rate measuring device of claim 1, wherein the first electrode and the second electrode are used to detect the electrocardiographic signals.

3. The heart rate measuring device of claim 1, wherein the first electrode and the second electrode are used to detect electrocardiographic signals, the signal processing unit used to process the detected electrocardiographic signals.

4. The heart rate measuring device of claim 1, wherein the heart rate measuring device is off when the first electrode and the second electrode are not both in contact with both hands of the subject.

5. The heart rate measuring device of claim 1, wherein the optical indicating units include a first optical indicating unit, a second optical indicating unit, a third optical indicating unit and a fourth optical indicating unit, indicating that the subject is detected with cardiac arrhythmia as all four lights are on or flashing.

6. The heart rate measuring device of claim 1, wherein the optical indicating units include a first optical indicating unit, a second optical indicating unit, a third optical indicating unit and a fourth optical indicating unit, indicating that the heart rate of the subject is too slow as the first optical indicating unit is on.

7. The heart rate measuring device of claim 6, wherein when the second optical indicating unit is on, the subject'"'"'s heart rate is normal.

8. The heart rate measuring device of claim 6, wherein when the third optical indicating unit is on, the subject'"'"'s heart rate is a little fast.

9. The heart rate measuring device of claim 6, wherein when the third optical indicating unit is on, the subject'"'"'s heart rate is too fast.

10. The heart rate measuring device of claim 1, further including an audio indicating unit coupled to the control unit.

11. The heart rate measuring device of claim 10, wherein the audio indicating unit makes a sound with each heart beat along the electrocardiographic signals.

12. A heart rate measuring method, used to measure a subject'"'"'s heart rate, comprising:

providing a first electrode and a second electrode;

providing a plurality of optical indicating units;

when the first electrode and the second electrode are both in contact with the subject, the device starts measuring the heart rate of the subject to generate electrocardiographic signals; and

controlling the optical indicating units to output the electrocardiographic signals.

13. The heart rate measuring method of claim 12, wherein the first electrode and the second electrode are both used to detect the electrocardiographic signals.

14. The heart rate measuring method of claim 12, wherein the heart rate measuring progression is stopped when the first electrode and the second electrode are not both in contact with the subject'"'"'s hands.

15. The heart rate measuring method of claim 12, wherein the optical indicating units include a first optical indicating unit, a second optical indicating unit, a third optical indicating unit, and a fourth optical indicating unit, when all the optical indicating units are on or flashing, indicating that the subject is detected with cardiac arrhythmia as all four lights are on or flashing.

16. The heart rate measuring method of claim 12, wherein the optical indicating units include a first optical indicating unit, a second optical indicating unit, a third optical indicating unit and a fourth optical indicating unit, indicating that the heart rate of the subject is too slow as the first optical indicating unit is on.

17. The heart rate measuring method of claim 16, wherein when the second optical indicating unit is on, the subject'"'"'s heart rate is normal.

18. The heart rate measuring method of claim 16, wherein when the third optical indicating unit is on, the subject'"'"'s heart rate is a little fast.

19. The heart rate measuring method of claim 16, wherein when the third optical indicating unit is on, the subject'"'"'s heart rate is too fast.

20. The heart rate measuring method of claim 16, further including an audio indicating unit coupled to the control unit, the audio indicating unit making a sound with each heart beat along the electrocardiographic signals.
