The present invention relates to a portable biosignal integrated sensing device and a remote medical information service system and method using the same, and more particularly, to a portable biosignal integrated sensing device for identifying a wearer's identity and recognizing a complex biosignal of the wearer; The present invention relates to a remote medical information service system and method for receiving a complex biosignal of a wearer collected using the portable biosignal integrated sensing device at a remote location, analyzing a physiological state of the wearer, and serving the information.

Currently, there are two major technologies related to remote medical information services. The first method is to collect a single bio-signal with a single sensor and transmit the collected single bio-signal directly wirelessly. The second method is that the ECG-testing equipment is It is a method of detecting the wearer's electrocardiogram and then storing the electrocardiogram data and then transmitting the stored data directly to a medical institution.

The first method is the "CodeBlue: Wireless Sensor Networks for Medical Care" technology disclosed at http://www.eecs.harvard.edu/~mdw/proj/codeblue/.

This conventional CodeBlue device includes a single sensor and a low-power microcontroller (Atmel Atmega 128L or TI MSP430) and a low-power digital spread spectrum radio (Chipcon CC2420, compliant with IEEE 802.14.4). , 2.4GHz, approximate range 100 meters, data rate about 80Kbps).

This includes clinic and hospitals.

The second method is for the electrocardiogram test, that is, the Holter test, and the wearer attaches the ECG test device for 24 hours and measures the state of the heartbeat. This test is useful for detecting such temporary arrhythmias when arrhythmias, such as arrhythmia, do not continuously occur and then disappear temporarily. In other words, this second method collects electrocardiogram information and reads the cardiologist from the collected results to determine the presence and severity of arrhythmia.

The first conventional method described above is not able to transmit a plurality of bio-signals for the medical treatment of the wearer, so that the wearer's condition cannot be accurately understood, and the identification of the identity between the device wearer and the person in need of the medical treatment is prevented. Since it is impossible to ensure the consistency of the data sent and received, the reliability of the data for medical services is low and the validity cannot be guaranteed. In other words, the conventional methods cause the biometric information to be confused in diagnosis, treatment, and treatment without the identity of the wearer clearly identified.

The second conventional method not only collects a single biosignal, but is performed only within a given range of time, and it is impossible to know in real time the exact physiological state of the wearer at a remote location. However, there is a problem that can not be used when it is necessary to provide continuous medical information.
