Description

TECHNICAL FIELD [0001] The present invention relates to a mobile terminal having a real-time blood pressure estimation monitoring function based on a bio-signal measurement and a measured bio-signal. [0002] MOBILE DEVICE HAVING FUNCTIONS OF MEASURING BIO-SIGNALS AND REALTIME-MONITORING BLOOD PRESSURE ESTIMATION BASED ON MEASURED BIO-SIGNALS [

The present invention relates to a mobile terminal having a function of measuring a user's various bio-signals and estimating the blood pressure of a user based on the measured bio-signals in real time, and more particularly, to a mobile terminal having an ECG sensor A PPG sensor module (optical sensor module) having a module, a light emitting portion and a light receiving portion is formed in the main body of the mobile terminal and the ECG, the photoelectrical pulse wave (PPG), the oxygen saturation (SpO ₂ ) The present invention relates to a mobile terminal having a function of measuring a user's various bio-signals and estimating the blood pressure of a user based on the measured bio-signals in real time.

Recently, the rapid development of science and technology has greatly improved the quality of life of the whole human being, and many changes have occurred in the medical environment. In the past, medical imaging of X-ray, CT, fMRI, etc. in the hospital could be done only for a few hours and a few days.

However, a video archive and transmission system (PACS, Picture Archive Communication System) has been introduced for capturing medical images for more than 10 years and then transferring the images directly to the monitor screen of a radiologist to read the images immediately. In addition, ubiquitous healthcare-related medical devices capable of confirming their blood sugar and blood pressure anytime and anywhere without going to a hospital are being developed and distributed.

In particular, in the case of hypertension, which is a major cause of various diseases and the prevalence of which is increasing, there is a need for a monitoring system that continuously informs the measured blood pressure information by measuring the blood pressure in real time. .

In one of these studies, blood pressure was measured in real time by inserting a blood pressure sensor into the pulmonary artery of a patient with chronic heart disease, and then transmitted to the primary care physician using wireless communication. As a result, Ubiquitous Healthcare (u_Health, ubiquitous Healthcare), which monitors and transmits prescriptions to patients, has been proposed to dramatically reduce the number of times patients are required to enter the hospital. However, although this method has an advantage that it can continuously and accurately measure blood pressure, since it is implemented by an invasive method, there is a problem that it is accompanied with difficulty in operation, risk of arterial injury, infection and the like. Therefore, this method is used only when necessary.

In recent years, there has been a continuous study on a method for real-time measurement of blood pressure through a non-invasive method without inserting a sensor for blood pressure measurement into an arterial blood vessel. In addition, studies have been carried out to monitor the blood pressure in the ubiquitous environment, and to allow the user to adjust the blood pressure by biofeedback the measured blood pressure to the user.

As a non-invasive blood pressure measurement method, there is a method of measuring blood pressure by attaching a cuff to an arm. However, in the case of using the cuff, there is a problem that it is difficult to measure the blood pressure continuously because somebody (the user himself or others) has to operate the blood pressure monitor to measure the blood pressure.

Therefore, it is necessary to introduce a system that enables the patient to receive emergency treatment within a short time by notifying the patient of the risk of hypertension in a short time by constantly monitoring the blood pressure by constantly monitoring the blood pressure while being constructed in a non-invasive manner It is true.
