The present invention relates to an ear implantable health monitoring apparatus using a piezo sensor for monitoring a sleeping habit.

In order to maintain good health, which is the basic requirement of a happy life, proper righteousness, food, and state must be secured. Among these three, eating habits directly affect health, so maintaining proper diet Most importantly, bad eating habits, such as being rushing into a busy daily life and being hungry, are soaked in the body, which often causes health problems.

In addition, even if you do not get enough sleep in your daily life, your health will be abnormal.In modern society, the population with abnormal sleep disorders or disorders is rapidly increasing due to stress, night light and noise pollution. Quantitative deterioration lowers body function and causes big accidents, thus creating a comfortable sleeping environment.

In particular, snoring during sleep indicates difficulty in breathing during sleep. Such snoring is one of lifestyle-related diseases, which is likely to develop not only sleep disturbance but also sleep apnea, cardiovascular, cerebrovascular disease, and high blood pressure. , Diabetes, etc., and the snoring population during sleep is increasing due to the increase in the obese population.

On the other hand, if you know your eating habits and sleeping habits, you can correct some of the wrong eating habits by your own efforts. Therefore, in recent years, you can monitor your eating habits and / or sleep habits to correct these wrong eating habits and sleeping habits. An apparatus has been proposed, and the beauty and health monitoring system disclosed in Japanese Patent Application Laid-Open No. 2013-39160 is one example of such an eating or sleeping habit monitoring device.

In the present invention, using the piezofilm having a frequency response band of 5 Hz to 5 kHz as described above, the biosignals such as electrocardiograms are mainly distributed in the low frequency bands as described above, except for the growth of the human body. This is because the signal can be measured effectively.

An acceleration sensor 30 is installed inside the main body 10 to detect a change in posture of the user due to the movement of the user during sleep, and the acceleration sensor 30 moves the x, y, and z axes. A three-axis acceleration sensor is used to detect each of them. In the present invention, the acceleration sensor 30 is implemented using the acceleration sensor of the CMA3000-A01 model with low power and 3D-MEMS technology. In addition to its high sensitivity, the built-in analog-to-digital conversion function and digital low-band filter function make it simple and easy to use.

The Bluetooth module 40 is provided inside the main body 10 so that the user's real-time biosignal detected by the piezoelectric sensor 20 and the acceleration sensor 30 can be transmitted to the portable terminal 1 such as the smartphone 1 '. Is installed, the signal obtained through the Bluetooth module 40 is wirelessly transmitted to the portable terminal 1, such as a smartphone (1 '), so that the user using the portable terminal (1) and eating habits and sleep habits and By selecting and outputting the related information, the user's eating habits and sleeping habits can be easily checked through the display of the portable terminal 1.

The controller 10 may acquire data by the piezo sensor 20 and the acceleration sensor 30, and transmit the obtained data to the portable terminal 1 using the Bluetooth module 40. 50, the piezoelectric sensor 20, the acceleration sensor 30, the Bluetooth module 40 and the control unit 50 is provided with a power supply unit 60 to supply power by a battery or the like, respectively.

Hereinafter, when using the health monitoring device of the present invention having the structure as described above, the user first to fix the monitoring device by inserting the main body 10 to the appropriate depth in his ear, then the monitoring program (or app) portable When the command to start monitoring using the terminal 1, the control unit 50 installed inside the main body 10 receives the signals detected from the piezo sensor 20 and the acceleration sensor 30 through the Bluetooth module 40, respectively. Wirelessly transmits to the portable terminal 1, the portable terminal 1 outputs the transmitted signal as a waveform according to the user's choice, and analyzes the signal and waveform and displays the results of the user's eating habits and sleep Allows you to monitor your habits.

To this end, the monitoring program analyzes various types of waveforms and frequency characteristics, inputs the analyzed results in a look-up table form, and includes a piezo sensor 20 and an acceleration sensor built in the main body 10. 30) It analyzes the signal transmitted from the back and compares the analysis result with the data stored in the lookup table to indicate whether the user is currently drinking water or chewing meat so that the user's eating habits and sleeping habits can be monitored. In the following, for example, it will be described in more detail.

The monitoring program of the present invention is driven using a dedicated portable terminal 1 or driven by an app (APP) for a smartphone 1 ′, in which the piezo is embedded in the main body 10 as described above.

The waveform and frequency characteristics pre-stored in the form of a look-up table in the portable terminal 1 include, for example, the sound of the upper and lower teeth striking by vertical movement when the food is first bited. 4a and 4b has a waveform and frequency characteristics, and when using the upper teeth and lower teeth when chewing food as shown in Figures 5a and 5b with a relatively large waveform and Has frequency band characteristics.

And when drinking water or beverages, such as the sound generated while the water is continuously passed to the neck as shown in Figs. 6a and 6b has a low and continuous waveform while having a lower frequency than the frequency band of biting and chewing food Has a band.

In addition, when speaking, as shown in Figure 7a and 7b shows a continuous waveform at regular intervals and accordingly has a wide frequency band, the snoring sound is the soft structure around the nose, soft palate, throat and the air during sleep Is a sound and vibration generated while vibrating, and in this case has a range of frequency bands as shown in FIGS. 8A and 8B.

If you look at the frequency band of vibration that appears according to the user's behavior, the frequency band of about 4 ~ 100Hz when ingesting food, such as when biting food, chewing and drinking water, has a frequency band of about 50 ~ 400Hz when speaking In addition, the snoring vibration during sleep has a frequency band in the range of about 100 to 500 Hz.

In addition, even in the case of ingesting food, vibration characteristics such as waveform and frequency are different depending on whether the user is ingesting vegetables or meat, and when ingesting vegetables, a certain amplitude as shown in FIGS. 9A and 9B. While the waveform has a characteristic of being regularly formed, the amplitude and waveform are irregularly formed as shown in FIGS. 10A and 10B when meat is ingested.

Therefore, the present invention displays whether the user is quickly chewing food, ingesting vegetables, etc. through the portable terminal 1 for analyzing and displaying the frequency band and waveform characteristics of vibrations that are different for each user's behavior as described above. Will be able to easily know their eating habits in real time.

In addition, the monitoring device of the present invention has a built-in acceleration sensor 30 it can detect movements such as flipping during sleep, so that the user monitors his eating habits and sleeping habits using the portable terminal (1) By doing so, you can try to identify and fix bad eating habits.

As described above, the health monitoring device of the present invention is compact and easy to use because it is inserted into the ear and is not inconvenient in daily life, and since the piezo sensor and the acceleration sensor are embedded therein, the oral cavity and the like during food intake can be used. By accurately detecting and displaying the oscillation characteristics of the skull and the movement characteristics due to reversal during sleep, the user can easily monitor the user's sleeping habits and eating habits.
