The present invention relates to a mobile phone capable of measuring pulse and blood pressure, and in particular, sets a maximum value of pulse rate or blood pressure to prevent stroke due to hypertension of blood pressure and maintains a smooth communication. The present invention relates to a mobile communication terminal capable of measuring a pulse and blood pressure after output and a method thereof.

Generally, the central processing unit (CPU) has been added by adding a function to check and record the pulse rate with a personal computer by adding a pulse rate measuring device to a personal computer used in a home, which is an essential equipment of modern people, which is increasing in recent years. And the monitor displays the pulse rate measured by the pulse rate measurement program, and stores it in the memory unit so that the health status can be checked with reference to it.

Referring to FIG. 1, a conventional pulse rate measuring apparatus using a personal computer includes a hard unit including a monitor unit 7, a keyboard unit 6, and a central processing unit (CPU) 4 and a memory unit 5. In the personal computer consisting of 10), the pulse rate including the sensor unit 1 for pulse rate measurement and the A / D converter (2) for A / D conversion of the output of the sensor unit 1 provided to the CPU (4) It consists of the measuring part 3.

The keyboard 6 sets a button for operating the pulse rate measuring unit 3, and the pulse rate measuring unit 3 and the hard unit 10 are connected by RS232, and the measured pulse rate is measured by the memory unit ( 5), the pulse rate and level are judged by the pulse rate measuring program, and the pulse rate measured by the monitor unit 7 is displayed.

The pulse rate measuring unit 3 is connected to the external terminal of the personal computer and the RS232 unit is connected and using a removable.

A pulse rate measuring method using a personal computer includes a filtering step of initializing a system to execute the pulse rate measuring program, converting a pulse detected from a human body into an electrical signal, amplifying the detected pulse signal to a predetermined level and simultaneously removing noise; Operating the sensor unit and the A / D converter of the pulse rate measuring unit and then performing A / D conversion; And counting square wave pulses at a counter connected to the central processing unit (CPU) 4 to store the pulse rate measurement results in the memory unit 5 and outputting them to the monitor unit 7. Steps.

In addition, the blood pressure (including heart contraction pressure and diastolic pressure) measurement using the two cuffs to measure the electronic sphygmomanometer clinically adopts auscultation method and oscillometric method.

In the method of auscultation, the cuff, which is a wrap around the upper arm, is wound around the upper arm, and a pressured stethoscope is placed in front of the elbow. If the pressure in the cuff is small, the blood easily fills the artery. Even if there is a pulse, the stethoscope will not hear anything. However, if the intracuff pressure is high enough to block the arterial blood flow during any interval of the heartbeat cycle, you will hear a Korotkoff sound from your stethoscope as your heart beats.

To measure blood pressure using the auscultation method, Knob first applies pressure to the cuff rather than arterial systolic pressure. The arteries of the arm will compress and block the blood flow. Korotkoff will not be heard. When the pressure in the cuff decreases slightly below the heart contraction pressure of the artery, some blood will flow through the blood vessel under the cuff. In heart rate, you will hear a synchronized tap sound in the artery in front of the elbow. At the same time you hear the sound, the pressure detected by the pressure sensor connected to the cuff is read. This is almost the same as the systolic pressure.

The stethoscope method has the advantage of high accuracy. Stethoscopes, however, cannot be used by non-specialists because they are used to monitor Korotkoff sounds, a basic skill for professionals.

The oscillometric method uses electronic sensors to detect arterial blood vessel waveforms and evaluates high and low pressures using experimental parameters. The oscillometric method has the advantage that the measurement is convenient and portable. However, high and low pressures are obtained according to the parameters evaluated. Although these parameters follow the characteristics of most users, they are not applicable to some special users such as atherosclerosis and diabetic patients.
