Abstract

Disclosed is a wrist wearable blood pressure monitor which is convenient to take blood pressure since it is mounted to a wrist at ordinary times, and is capable of accurately measuring the blood pressure even though it has a simple structure without a cuff, a pump or the like, and transmitting the blood pressure through wireless communication so that the blood pressure can be efficiently managed.

To this end, the wrist watch style blood pressure monitor that can be mounted to a wrist of an examinee at ordinary times includes: a blood pressure monitor main body which includes a measured blood pressure display to display measured blood pressure of an examinee; a band which is coupled to the measured blood pressure display and wound around a wrist; an air chamber which is provided at one side of the band and filled with air to compress a skin surface of a wrist; and a pressure sensor which is provided to measure blood pressure from an aorta radialis when the air chamber is compressed for pressing the aorta radialis. According to an embodiment of the present invention, the blood pressure monitor is wearable at ordinary times like a wrist watch, is convenient to measure the blood pressure as necessary, and is capable of accurately measuring the blood pressure even though it has a simple structure without a separate pump.

Claims

1. A wrist watch style blood pressure monitor that can be mounted to a wrist of an examinee at ordinary times, comprising:

a blood pressure monitor main body which comprises a measured blood pressure display to display measured blood pressure of an examinee;

a band which is coupled to the measured blood pressure display and wound around a wrist;

an air chamber which is provided at one side of the band and filled with air to compress a skin surface of a wrist; and

a pressure sensor which is provided to measure blood pressure from an aorta radialis when the air chamber compresses the aorta radialis.

2. The wrist watch style blood pressure monitor according to claim 1, wherein the band comprises a single-body elastic band which has elasticity and of which diameter can be enlarged by external force.

3. The wrist watch style blood pressure monitor according to claim 1, wherein the air chamber comprises silicon, urethane or rubber.

4. The wrist watch style blood pressure monitor according to claim 1, wherein the pressure sensor is provided at a side of the measured blood pressure display, and is connected to the air chamber by an air hose through which change in pressure is transferred to the pressure sensor.

5. The wrist watch style blood pressure monitor according to claim 1, wherein the pressure sensor is provided inside the air chamber, and an input value detected by the pressure sensor is transmitted to the measured blood pressure display through a signal line.

6. The wrist watch style blood pressure monitor according to claim 1, wherein the air chamber further comprises an air inlet to adjust pressure of air injected therein.

7. The wrist watch style blood pressure monitor according to claim 1, further comprising a wireless communication unit to send a value of the measured blood pressure to a set Smartphone.

8. The wrist watch style blood pressure monitor according to claim 2, further comprising a wireless communication unit to send a value of the measured blood pressure to a set Smartphone.

9. The wrist watch style blood pressure monitor according to claim 3, further comprising a wireless communication unit to send a value of the measured blood pressure to a set Smartphone.

10. The wrist watch style blood pressure monitor according to claim 4, further comprising a wireless communication unit to send a value of the measured blood pressure to a set Smartphone.

11. The wrist watch style blood pressure monitor according to claim 5, further comprising a wireless communication unit to send a value of the measured blood pressure to a set Smartphone.
