Problems solved by technology

However, since the elderly in our country mainly adopt the "home care" mode of care, and the early symptoms of the disease are not obvious and concentrated, it is unrealistic to hire professionals for long-term escort and observation, and family members usually lack relevant professional knowledge. When the elderly have abnormalities, on the one hand, because they do not have professional knowledge, they cannot judge whether they are sick or not. , psychological factors and other reasons lead to inaccurate descriptions by family members or the elderly, so that early identification and diagnosis cannot be carried out in a timely and accurate manner.

example 1

[0043] Example 1: By cooperating with medical institutions to understand the relevant information of elderly people suffering from cognitive impairment diseases or potential diseases, the video module of the system is used to monitor the daily home behavior of these elderly people, and the system The video module is connected with the identification module, and the identification module is used to obtain the characteristic video of the abnormal behavior at home. Summarize and summarize the abnormal behavior characteristics at home of the elderly with cognitive impairment diseases or potential diseases. Abnormal behavior characteristics include the elderly's sleep, eating, dressing, sports and entertainment, etc., such as: not being able to use tableware well, grabbing food with hands; staring and not eating; playing with food or non-food items; Repeatedly walks in a routine; follows others multiple times; can't find the exact location of an object, or repeatedly looks for it; ...

example 2

[0053] Example 2: On the basis of Example 1, set up the doctor terminal and the family terminal, the doctor terminal is the computer in the hospital office, the family terminal is the family computer or mobile phone, and the camera selects the webcam. Scoring rules can be stored on the doctor side and family side, and can also be stored on the cloud. Family members can choose whether to save the elderly’s daily home videos and abnormal behavior videos locally or in the cloud, and turn on or off the network function of the camera. Through the network function of the camera, you can view the surveillance video in real time at home or outside, retrieve the saved daily home videos and abnormal behavior videos of the elderly, and retrieve the scoring rules to fill in. Turning off the network function of the camera supports viewing and comparison at home.

[0054] In addition, if family members need doctor assistance, they can invite doctors to participate remotely through the doct...

Abstract

The invention discloses a video-based cognitive function defect assessment system and device for the elderly, belonging to the interdisciplinary field of medicine, architecture and public management. The system and device use video surveillance technology to observe and track the daily home life of the sick elderly for a long time, collect and summarize the abnormal behavior characteristics of the elderly, and match these behavior characteristics with the cognitive function defect scoring rules based on abnormal home behavior. Therefore, the cognitive function of the elderly can be evaluated according to the scoring rules based on abnormal home behaviors, which can realize the early identification and diagnosis of diseases related to cognitive function deficits of the elderly at home. The system and device of the present invention are simple and easy to understand, have strong operability, and can objectively and clearly reflect the possibility of the elderly at home suffering from diseases related to cognitive function defects. Early prediction and diagnosis are of great significance.

Description

technical field [0001] The invention belongs to the interdisciplinary field of medicine, construction and public management, and more specifically relates to a method of collecting behavioral information through video monitoring, and using cognitive scoring rules based on abnormal home behaviors to judge the cognitive function of the elderly at home A situation assessment system and device, the system and device are helpful for early identification and timely intervention of home-based senile dementia, depression and other cognitive impairment diseases. Background technique [0002] With the continuous development of my country's aging population, more and more elderly people begin to suffer from cognitive impairment-related diseases. According to the report of the World Health Organization in December 2017, more than 20% of people aged 60 and over suffer from cognitive impairment-related diseases (excluding headache disorders), the most common of which are dementia and depr...
