본 발명은 피에조 센서를 이용한 귀 삽입형 건강 모니터링 장치에 관한 것으로, 더욱 상세하게는 사용자의 귀 속에 삽입되어 음식물의 저작운동에 따른 진동패턴과 수면 시의 코골이 및 뒤척임 등을 검출하여 사용자의 식습관과 수면습관 등을 모니터링하는 피에조 센서를 이용한 귀 삽입형 건강 모니터링 장치에 관한 것이다.The present invention relates to an ear insertion type health monitoring apparatus using a piezo sensor, and more particularly, is inserted into a user's ear to detect a vibration pattern and snoring and snoring at the time of food chewing movement and the user's eating habits. The present invention relates to an ear implantable health monitoring apparatus using a piezo sensor for monitoring a sleeping habit.
행복한 삶의 기본 요건인 건강을 유지하기 위해서는 의(衣), 식(食), 주(住)를 적절히 확보하여야 하며, 이 세 가지 중에서도 식생활은 건강에 직접적인 영향을 끼치기 때문에 적절한 식생활을 유지하는 것이 무엇보다 중요함에도 바쁜 일상에 쫓겨 음식을 급하게 먹는 등과 같은 잘못된 식습관이 몸에 배게 되고, 이로 인해 건강을 해치는 경우가 종종 발생되고 있다.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.
또한 일상생활 중에 충분한 수면을 취하지 않는 경우에도 건강에 이상이 오게 되는데, 현대 사회에서는 스트레스, 야간의 빛이나 소음공해 등의 원인으로 수면이상이나 장애를 가진 인구가 급격히 증가하고 있으며 이러한 수면의 질적, 양적 저하는 신체기능을 저하시키는 동시에 큰 사고의 원인이 되고 있으며, 따라서 쾌적한 수면환경의 조성이 필요하다.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.
특히 수면 중의 코골이는 수면 시 호흡곤란이 있음을 나타내는 것으로, 이러한 코골이는 생활습관에 의한 질환 중의 하나로서 단순히 수면방해 뿐 아니라 수면 무호흡증으로 발전할 가능성이 높고 심혈관계, 뇌혈관 관련 질환, 고혈압, 당뇨병 등의 원인이 되기도 하며, 비만인구의 증가 등으로 인해 수면 중에 코골이를 하는 인구가 계속 증가하고 있다.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.
한편, 자신의 식습관과 수면습관을 알게 되면 스스로의 노력에 의해 잘못된 식습관 등을 어느 정도 고칠 수 있으며, 따라서 최근에는 이러한 잘못된 식습관과 수면습관을 바로 잡기위하여 식습관 및/또는 수면습관을 모니터링할 수 있는 장치가 제안되고 있는데, 이러한 식습관 또는 수면습관 모니터링 장치에 대한 하나의 예로서 일본 공개특허공보 특개2013-39160호에 개시된 미용·건강 모니터링 시스템을 들 수 있다.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.
상기 특허문헌에 개시된 미용·건강 모니터링 시스템은 귀에 삽입하여 사용 할 수 있는 구조로서, 표면에는 온도 검출수단, 습도 검출수단 및 혈류맥파 검출수단을 구비하여 사용자의 생체정보를 검출하는 생체정보 검출수단, 내부에 구비된 생체 동작을 검출하기 위한 상태치 검출수단, 이들 생체정보 검출수단과 상태치 검출수단을 구비하여 귀에 장착되는 장착구로 이루어지고, 사용자 신체의 기울기와 움직임 등을 측정할 수 있도록 가속도 센서, 자이로 센서를 구비하며, 혈류와 맥파를 측정하기 위한 센서, 체온을 검출하기 위한 적외선 센서 등을 구비한 것으로, 이러한 구성에 의해 생체 동작데이터와 여러 가지의 각종 생체 정보데이터를 표시하여 사용자의 건강 상태를 모니터링할 수 있도록 한 것이다.The beauty and health monitoring system disclosed in the patent document has a structure that can be inserted into the ear, and has a temperature detecting means, a humidity detecting means and a blood flow pulse detecting means on its surface to detect the biological information of the user, It consists of a state value detection means for detecting the living body movements provided inside, these mounting information mounting means equipped with the biological information detection means and state value detection means, the acceleration sensor to measure the inclination and movement of the user's body, etc. , A gyro sensor, a sensor for measuring blood flow and pulse wave, an infrared sensor for detecting body temperature, and the like, which display the biometric data and various biometric data for the user's health. The status can be monitored.
그러나 상기의 미용·건강 모니터링 시스템은 사용자의 심박수와 체온의 변화 및 운동량 등에 따른 신체의 움직임을 검출함으로써 사용자의 생활 운동량과 건강 상태 등을 모니터링하는 것으로 사용자의 식습관이나 수면 시의 코골이나 뒤척임 과 같은 수면습관 등은 제대로 모니터링하지 못한다는 단점이 있다.However, the above beauty and health monitoring system monitors the user's daily exercise and health status by detecting the body's movement according to the user's heart rate, body temperature change, and exercise amount, such as snoring or overturning during user's eating habits or sleep.
