The PPG sensor 110 measures the amount of blood flow through the fingertip of the subject according to the heartbeat by using the principle that hemoglobin in the blood absorbs light of a specific wavelength (eg, infrared band light). The light of the infrared band output from the light emitting diode 110a is transmitted through the skin surface of the finger of the examinee and then reflected and incident on the photo transistor 110b. The phototransistor 110b receives incident light and converts the incident light into an electrical signal and outputs the electrical signal.

The PPG signal output from the PPG sensor 110 is amplified by the first amplifier 112 and is input to the first A / D converter 114.

The ECG signal output from the ECG sensor 120 is amplified by the second amplifier 122 and is input to the second A / D converter 124. The second A / D converter 124 converts the analog ECG signal output from the second amplifier 122 into a digital form and outputs the digital form. The ECG signal converted by the second A / D converter 124 is provided to the controller 140.

The storage unit 130 stores various control programs and body index information of the examinee necessary to implement the functions of the mobile communication terminal. Here, the body index information of the subject is information on the date of birth, sex, weight, and height, and is used when diagnosing the health state of the subject. In this case, the body index information of the examinee is preferably stored separately for each identifier (ID) of the examinee.

In addition, the storage unit 130 may analyze the diagnostic information including the heart rate, the lowest blood pressure and the highest blood pressure of the subject, and diagnose cardiovascular abnormalities such as heart abnormalities and aneurysm abnormalities from the shapes of the PPG and ECG. Diagnostic programs for diagnosing a state of health may be stored.

The controller 140 performs overall operations of the mobile communication terminal according to the control program stored in the storage 130. First, the mobile communication terminal according to the present invention operates in a general call mode and a health diagnosis mode. Here, the health diagnosis mode includes an input mode for receiving information on the subject, a measurement mode for measuring the health of the subject, an analysis mode for analyzing the measured results, and a storage mode for storing the measurement results and diagnostic results. It is composed.

Looking at the control operation of the control unit 140 according to the health diagnostic mode according to the present invention as follows. First, the controller 140 includes the subject's heart rate per minute, the lowest blood pressure, and the highest blood pressure by using the PPG and ECG data output from the first and second A / D converters 124 and the body index information of the subject. Obtain diagnostic information. Here, the heart rate per minute of the subject can be obtained by counting the number of peaks in the PPG or ECG data, and converting the count into minutes, and the lowest blood pressure and the highest blood pressure of the subject are shown in FIG. The time difference (TEP) of the liver can be obtained and compared with the body index information of the subject.

The controller 140 stores the diagnostic information including the heart rate, the lowest blood pressure, and the highest blood pressure information of the subject obtained through the above process on the display unit 150 and the display unit 130.

Next, the controller 140 diagnoses the health state of the subject by using the obtained diagnostic information. In this case, the health condition of the examinee may be diagnosed by using a diagnostic program stored in the storage 130 or through an external health diagnosis server (not shown) connected through a mobile communication network.

The communication unit 160 receives data transmitted from an external health diagnosis server connected through a mobile communication network and provides the data to the control unit 140 or under the control of the control unit 140, the PPG, ECG information, and the examinee stored in the storage unit 130. It transmits the body index information and the health check information of the subject to the external health check server.

As shown in FIG. 2, the key matrix 170 according to the present invention includes a PPG sensor 110 for measuring PPG and an ECG sensor for measuring ECG, in addition to numeric keys and function keys provided in a general mobile communication terminal. 120 and a health diagnostic mode key 172 are provided.

4 is a flowchart illustrating a health diagnosis method according to an exemplary embodiment of the present invention.

1 to 4, when the health diagnosis mode key 172 provided in the key matrix 170 is selected (S200), the controller 140 displays a message for requesting ID input through the display unit 150. .

In response to the message, when the examinee's ID is input through the key matrix 170 (S205), the controller 140 determines whether the received ID is an ID registered in the storage 130 (S210).

If it is determined in step 210 that the received ID is the ID registered in the storage unit 130, the controller 140 induces the PPG sensor 110 and the ECG sensor 120 to position the subject's finger. After outputting the message to switch to the measurement mode to measure the PPG and ECG delivered to the subject's finger by the heart rate (S220). For example, the mobile communication terminal is held by the left hand and the first ECG electrode 120a provided on the side of the mobile communication terminal is held by the index finger or middle finger of the left hand, and the right hand index finger is the second ECG electrode 120b on the PPG. To put it on the

On the other hand, if it is determined in step 210 that the received ID is an unregistered ID, the controller 140 receives the subject information (date of birth, gender, weight, height, etc.) and assigns a new ID to step 220. Switch (S215).

When the PPG and ECG signals are measured in step 220, the controller 140 obtains diagnosis information including the heart rate, the minimum blood pressure, and the highest blood pressure per minute of the subject using the measured PPG, ECG signal, and the body index information of the subject. (S225).

In addition, the control unit 140 displays the obtained diagnosis information on the display unit 150 so that the examinee can check the stored diagnosis information and stores it in the storage unit 130 to diagnose the health state of the examinee (S230).

Thereafter, the controller 140 determines whether a diagnostic program capable of analyzing the health state of the subject exists in the storage 130 (S235). If it is determined in step 235 that the diagnosis program exists in the storage unit 130, the controller 140 analyzes the diagnosis information stored in the storage unit 130 using the diagnosis program to diagnose the health state of the subject. (S240).

When the health condition of the examinee is diagnosed by the diagnosis program, the controller 140 displays the health state information of the diagnosed test subject through the display unit 150 (S245).

On the other hand, if it is determined in step 235 that the diagnostic program does not exist in the storage unit 130, the control unit 140 is the external health diagnosis server to check the body index information and diagnostic information of the subject stored in the storage unit 130 The communication unit 160 is controlled to transmit to (S250).

Then, when the health status information of the examinee is received from the external health diagnosis server (S255), the controller 140 displays the health state information of the examinee received from the external health diagnosis server through the display unit 150 (S260).

When the storage command is received through the key matrix 170 after the step 245 or the step 260 (S265), the controller 140 stores the health state information of the subject displayed on the display unit 150 in the storage unit 130. (S270).

On the other hand, if the storage command is not received through the key matrix 170 after the step 245 or the step 260, the control unit 140 deletes the health state information of the subject displayed on the display unit 150 and ends.

On the basis of the present invention described above, in the case of extending the medical examination function of the present invention, more various information can be provided. For example, by adding a bio-sensor capable of sweat analysis, a wider state of health can be diagnosed by measuring a subject's fatigue or measuring blood glucose levels.
