Wrist watch style blood pressure monitor
A wrist watch style blood pressure monitor is configured to be mounted on a wrist of an examinee at ordinary times in order to measure and monitor blood pressure. The wrist watch style blood pressure monitor includes a blood pressure monitor main body which comprises a blood pressure display to display a blood pressure of the examinee. A band is coupled to the blood pressure display and is wound around the wrist of the examinee. An air chamber is provided at one side of the band and filled with air to compress a skin surface of the wrist. A pressure sensor is provided to measure the blood pressure from an aorta radialis when the air chamber compresses the aorta radialis.
1. A wrist watch style blood pressure monitor, comprising:
a main body which comprises a display to indicate a blood pressure of an examinee;
a band which is coupled to the main body and wound around a wrist of the examinee;
an air chamber which is provided at one side of the band and filled with air with a predetermined pressure to compress a skin surface of the wrist; and
a pressure sensor which is provided to measure a blood pressure from an aorta radialis based on a pressure change in the air chamber when the air chamber compresses the aorta radialis,
wherein the air chamber has no inlet through which air is injected into the air chamber from an outside of the wrist style blood pressure monitor, and is hermetic such that no air flows into and out from the air chamber, and
wherein the air chamber is manually compressed and then manually decompressed such that the pressure sensor senses pulse waves of the examinee.
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 display, and is connected to the air chamber by an air hose through which the pressure change in the air chamber 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 display through a signal line.
6. 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.
7. 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.
8. 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.
