Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a pulse measuring device of a portable terminal having a touch screen according to an embodiment of the present invention.

As shown in FIG. 1, the pulse measuring apparatus of a portable terminal having a touch screen according to an exemplary embodiment of the present invention includes a touch screen 10, a memory unit 30, a counter 50, an alarm unit 40, And a control unit 20.

The touch screen 10 is configured by any one of a resistive method, a capacitive method, a surface acoustic wave (SAW) method, or an infrared method to sense a touch position, and a user. Displays blood pressure measurement menu window or blood pressure value to measure blood pressure.

Here, the touch position refers to a position where a finger, a hand, a pulse, or the like touches (ie, touches) the touch screen 10.

The touch screen 10 includes a touch sensor 12 that senses a touch position, and a display unit 14 that displays the blood pressure measurement menu window or the blood pressure value.

In this case, the touch sensor 12 detects the touch position of the touch screen 10 and also R (resistance), C (capacitance), I (infrared ray), A according to the configuration of the touch screen 10. The value of any one of (surface ultrasonic waves) is detected.

The value of any one of R (resistance), C (capacitance), I (infrared ray), and A (surface ultrasonic wave) detected by the touch sensor 12 is transmitted to the control unit 20, and the control unit ( 20 stores the values transmitted from the touch sensor 12 in the memory unit 30.

The memory unit 30 is a program for processing and controlling the control unit 20, and input and output data (for example, R (resistance), C (capacitance), I (infrared rays), A (surface ultrasound) values) Temporarily stores the function.

The memory unit 30 may include a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory). ), RAM, or ROM.

The counter 50 measures a pulse by increasing its value one by one according to an input signal transmitted from the controller 20, and is generally implemented as a flip-flop or the like.

The alarm unit 40 outputs a sound indicating the start and completion of pulse measurement under the control of the controller 20.

According to the alarm sound of the alarm unit 40, the user who measures the pulse using the portable terminal with the touch screen can know the pulse measurement start time and the pulse measurement completion time.

The controller 20 controls the display unit 14 to display the blood pressure measurement menu window stored in the memory unit 30 on the display unit 14 so that a user can select a pulse measuring mode, and from the touch sensor 12. When the highest and lowest X coordinates and Y coordinates are transmitted, the coordinates are set as the sensing area and fixed.

In addition, when the value of any one of R (resistance), C (capacitance), I (infrared ray), and A (surface ultrasound) is transmitted from the touch sensor 12, the controller 20 changes the amount of change in the transmitted value. Detects and waits until the value is stabilized, and after the waiting for a certain time to determine whether the value changes to a constant rhythm to determine the presence of a pulse.

That is, when the value transmitted from the touch sensor 12 has a predetermined rhythm, the controller 20 determines that the value transmitted from the touch sensor 12 is a measured value based on a pulse and starts pulse measurement, and the touch If the value transmitted from the sensor 12 does not have a predetermined rhythm, it is determined that the pulse is not detected, and the user requests the movement of the pulse detection site so that the touch sensor 12 can scan the pulse detection site again.

The portable terminal having the touch screen may be any one of a mobile phone, a digital camera, an MP3 player, a personal digital assistant, and a portable multimedia player.

In other words, any device that is portable and equipped with a touch screen may be used as a pulse measuring device.

2 is a flowchart illustrating a pulse measuring method of a portable terminal having a touch screen according to an exemplary embodiment of the present invention.

As shown in FIG. 2, in the pulse measuring method of a portable terminal having a touch screen according to an embodiment of the present invention, the user first measures blood pressure (or pulse) among a plurality of menus displayed on the touch screen 10 of the portable terminal. Sensing) menu, the control unit 20 controls the touch screen 10 such that the portable terminal is in the blood pressure measurement mode.

Then, when the user touches the touch screen 10 of the portable terminal to the measurement site of his or her left or right cuff, the touch sensor 12 of the touch screen 10 displays the X and Y coordinates of the contacted area. Scan (S110).

In this case, the touch sensor 12 of the touch screen 10 detects the highest and lowest X coordinates and the Y coordinates of the contacted portion when scanning the X and Y coordinates of the contacted portion, and detects the detected highest and lowest X coordinates. And transmits the Y coordinate to the control unit 20 (S112).

When the highest and lowest X coordinates and Y coordinates are transmitted from the touch sensor 12, the controller 20 sets and fixes the corresponding coordinates as the sensing area (S114).

Meanwhile, when the touch sensor 12 of the touch screen 10 detects the highest and lowest X coordinates and Y coordinates of the contacted area, that is, the user touches the touch screen 10 near the wrist to measure the pulse. When a contact is made, any one of R (resistance), C (capacitance), I (infrared ray), and A (surface ultrasonic wave) is detected and transmitted to the controller 20.

At this time, the control unit 20 is a constant rhythm by changing the value of any one of R (resistance), C (capacitance), I (infrared ray), A (surface ultrasound) transmitted from the touch sensor 12. It is determined whether or not there is (S116, S118).

In other words, the controller 20 transmits any one of R (resistance), C (capacitance), I (infrared ray), and A (surface ultrasonic wave) from the touch sensor 12. When the amount of change is sensed and the value is stabilized, it is determined whether the value changes by a constant rhythm to determine the presence or absence of a pulse.

At this time, the reason why the control unit 20 waits for the transmitted value (any one of R (resistance), C (capacitance), I (infrared ray) and A (surface ultrasonic wave)) is stabilized is the user's touch screen ( 10) when the force applied to the touch sensor 12 and the touch screen 10 is in contact with the user's wrist when the contact with his wrist (that is, the touch screen 10 for a certain time on the user's wrist) This is because the force applied to the touch sensor 12 is different when the contact state is maintained.

That is, when the first user touches the touch screen 10 to his or her wrist, the values of R (resistance), C (capacitance), I (infrared), A (surface ultrasound) and the touch screen 10 are displayed. R (resistance), C (capacitance), I (infrared ray), A (surface ultrasound) values are different when the wrist is in contact with the wrist for a certain time. The controller 20 maintains the standby state for a predetermined time until the values of (capacitance), I (infrared ray), and A (surface ultrasonic wave) are stabilized.

In the step S118, when the values of R (resistance), C (capacitance), I (infrared ray), and A (surface ultrasound) have a constant rhythm, the controller 20 indicates that the alarm unit 40 starts pulse measurement. The alarm unit 40 is controlled to generate a sound (S120).

Accordingly, the user hears the sound generated by the alarm unit 40 and can know that the pulse measurement starts from the present time.

Meanwhile, the controller 20 controls the counter 50 so that the alarm 50 counts while the alarm 40 controls the alarm 40 to generate an alarm sound.

In other words, the control unit 20 provides an input signal so that the counter 50 counts the pulse number during pulse measurement, and the counter 50 according to the input signal transmitted from the control unit 20. The value is incremented by one and counted.

At this time, the input signal transmitted from the control unit 20 to the counter 50 is one of R (resistance), C (capacitance), I (infrared ray), and A (surface ultrasonic wave) transmitted from the touch sensor 12. Is generated by either value.

That is, the value transmitted from the touch sensor 12 (any one of R (resistance), C (capacitance), I (infrared ray), and A (surface ultrasound)) is changed in amplitude as the blood vessel contracts and expands. The controller 20 extracts only a frequency component of a value transmitted from the touch sensor 12 and converts the square wave into a square wave, and transmits the square wave to the counter 50.

Meanwhile, the blood pressure value counted by the counter 50 (that is, the number of pulses) is stored in the memory unit 30 (S122).

The control unit 20 controls the alarm unit 40 to output a sound indicating the completion of the pulse measurement after a predetermined time (for example, 10 seconds to 1 minute) (S124).

When the pulse measurement is completed as described above, the controller 20 adds the pulse measurement time and the date to the blood pressure value and stores it in the memory unit 30 (S126).

Thereafter, when the user requests a blood pressure value display, the control unit 20 controls the display unit 14 to display the blood pressure value and pulse measurement date and time stored in the memory unit 30 on the display unit 14. (S128).

On the other hand, the user can check his or her blood pressure value, pulse measurement date and time through the information stored in the memory unit 30 at any time.
