Remote home monitoring system and method thereof

technical field

The present invention relates to a remote home monitoring system and its method. When the system judges that an abnormal situation occurs in a user's activity behavior, the system stores image data of a period of time before and after the user's abnormal activity behavior occurs, so that When the user's relevant units or relevant contacts connect to the system, they will directly browse to the image data.

Background technique

Due to the advancement of medicine and the improvement of health and welfare, and the global average fertility rate has decreased year by year, people's health conditions and average life expectancy have increased significantly, and the resulting population structure tends to age. Under the population structure of the aging society, some medical and social welfare system problems related to the elderly and chronic diseases have also emerged as the times require. In response to this trend change, and to satisfy chronic patients who wish to receive health care in a home environment, the market demand for care and remote home care for the elderly or patients (hereinafter referred to as care recipients) is also increasing. Increase.

In recent years, due to the continuous advancement of information technology, the application of remote home care and telemedicine services has become more diversified. In order to solve the social problems brought about by the elderly population, advanced countries in the world have actively launched remote home care and telemedicine services. The research and promotion of medical services can not only help medical institutions achieve the goal of resource sharing and cost saving, but also effectively promote home care and medical services to remote areas with insufficient medical resources.

Generally speaking, the main function of the so-called "tele-home care" or "telemedicine service" is to help monitor the health status of the care recipient through the extraction and analysis of physiological parameters, and provide medical intervention at the most appropriate time , and "remote home care" or "telemedicine service" are technologies that use the Internet or telephone network to connect care recipients and family members in two places, or care recipients and doctors, and send the physiological parameters of care recipients (such as: blood pressure, heartbeat, or blood sugar level) and other information are sent to family members or doctors, and based on this, the current situation of the care recipient can be judged, so that real-time care can be given when the care recipient is unwell or in critical life. or medical services.

However, "remote home care" can only be used to notify the care recipient's family or doctor through Internet or telephone network technology after the physiological parameters of the care recipient indicate that an abnormal physiological state has occurred. Or after receiving the notification, although the doctor can get the information about the physiological state of the caregiver from the physiological parameters, he cannot obtain the activity behavior of the caregiver before the abnormal physiological state occurs through the physiological parameters, and these activities are often Important information for doctors during diagnosis and treatment, for example: after the abnormal physiological state of the care recipient, the phenomenon of unconsciousness occurs. Fainted to the ground due to a major impact, or the care recipient suffered external contusions, fractures, etc. during walking or after fainting. However, "remote home care" can only transmit the physiological parameters of the abnormal physiological state to the doctor, and Failure to notify physicians of activities of care recipients resulting in major impacts to the head, external contusions, fractures, etc.

Furthermore, "telemedicine service" usually measures various physiological parameters of the user by various testing instruments, and transmits various physiological parameters to the computer used by the doctor through the Internet, and the care recipient is photographed by a network camera. and the doctor, and transmit the captured images to the computer used by the doctor and the caretaker through the Internet, and transmit the conversation content between the caretaker and the doctor through the network voice receiving and transmitting device, and transmit the conversation content to the doctor and the caretaker through the Internet The computer used, in this way, the doctor can diagnose the care receiver based on various physiological parameters, pictures of the care receiver and conversation content. However, "telemedicine service" is a two-way conversation between the care recipient and the doctor in an awake state. If the care recipient is in an unconscious state, the care recipient cannot activate the "telemedicine service" at all. Therefore, " "Telemedicine service" has blind spots in the use of care recipients. It can even be said that "telemedicine service" does not help when the care recipient is unconscious.

Therefore, how to use the existing cheap broadband network to design a remote home monitoring system and method at a very low equipment cost to improve the shortcomings of remote home care or telemedicine services, especially when the care recipient is unconscious If the activity behavior before and after the state can be recorded and quickly browsed, it will help the doctor to make a diagnosis, which has become an important topic for the industry to study and hope to improve.
