Abstract

A portable biosignal measurement apparatus and the method is provided. The apparatus includes: a micro pump; a pressure supplier including a cuff which applies a pressure in a direction of a radial artery of a user'"'"'s wrist by a fluid, which is flowed depending on pressure provided by the micro pump; and a sensor unit to measure a biosignal using displacement of the radial artery.

Claims

1. A portable biosignal measurement apparatus, the apparatus comprising:

a control unit to control a fluid;

a pressure supplier including a cuff which applies a pressure in a direction of a radial artery of a user'"'"'s wrist by the fluid, which is flowed depending on the pressure; and

a sensor unit to sense a biosignal using displacement of the radial artery.

2. The apparatus of claim 1, wherein the control unit comprises:

a micro pump to apply the pressure to the fluid; and

a measurement control unit to measure the biosignal.

3. The apparatus of claim 2, wherein the measurement control unit further comprises a communication interface unit to transmit the measured biosignal to an external device.

4. The apparatus of claim 2, wherein the micro pump comprises a motor.

5. The apparatus of claim 1, wherein the pressure supplier further comprises:

a support member to support the cuff in order to extend the cuff in the direction of the radial artery.

6. The apparatus of claim 1, further comprising:

a fastening unit to fasten the portable biosignal measurement apparatus around the user'"'"'s wrist.

7. The apparatus of claim 1, wherein the control unit comprises:

a vessel to contain the fluid and to apply the fluid to the cuff by pressure which the micro pump applies.

8. The apparatus of claim 1, wherein the fluid is air.

9. The apparatus of claim 1, wherein the sensor unit is a pressure sensor to measure a pressure change of the cuff due to displacement of the radial artery, and

the biosignal is blood pressure.

10. The apparatus of claim 2, comprising:

a measurement unit to measure the blood pressure based on the pressure change of the cuff.

11. The apparatus of claim 3 wherein the communication interface unit to transmit the measured biosignal using a wired/wireless network to the external device.

12. The apparatus of claim 1, wherein the sensor unit comprises:

at least one pulse wave sensor to measure a pulse wave of the user'"'"'s wrist from the radial artery.

13. The apparatus of claim 1, wherein the sensor unit measures the user'"'"'s biosignal from a point in time when the pressure supplier starts applying pressure to the user'"'"'s wrist to a point in time when the pressure supplier applies a maximum amount of pressure to the user'"'"'s wrist.

14. The apparatus of claim 1, wherein a size of the cuff is smaller than the user'"'"'s wrist.

15. A method for measuring a biosignal, the method comprising:

applying a pressure in a direction of a redial artery of a user'"'"'s wrist by a fluid; and

measuring a biosignal of the user,

wherein the applying the pressure where only a portion of the user'"'"'s wrist near the redial of the user'"'"'s wrist.
