What to do if an elderly person falls? Millimeter-wave radar can help you solve the problem

Statistics show that about 40 million elderly people in my country slip and fall every year due to slippery floors, 50% of which happen in the bathroom. Falling is the leading cause of death due to injury for people over 65 years old. The older you are, the higher the risk of falling and being injured or dying.

The risk factors that cause falls may be hidden in every part of the home living space. Some seemingly harmless inconveniences may pose fatal risks to the elderly.

Starting from the age of 60, some signs of aging will gradually become obvious, such as hunched back, slower movements than before, slower reactions, reduced color discrimination, decreased spatial perception, etc., and physical aging leads to many inconveniences, such as: weakened kidney function leading to frequent and urgent urination, angina pectoris, getting up after defecation can easily induce cerebral ischemia leading to dizziness, blurred vision, and falls, the closed and oxygen-deficient bathing environment, temperature changes causing blood pressure fluctuations, easy falls when getting up at night, etc.

In an ideal future, smart devices throughout the home will be able to collect data on the lives of the elderly, conduct big data analysis, and integrate their related devices and terminals to achieve instant delivery of effective resources at critical moments.

Currently, there are health bracelets for elderly people to alarm when they fall, but this kind of equipment needs to be worn by the elderly and needs to be charged, which cannot be solved well. Millimeter wave radar can solve this problem. It can be installed at home to alarm when someone falls. You can see the effect:

The basic principle of bio-radar:

The contactless health sensing device (referred to as bio-radar) transmits 24GHz radar waves to the human body and then analyzes the vital signs from the reflected waves. Both the transmitting and receiving antennas have certain directional angles. To ensure the effectiveness and accuracy of monitoring, the device needs to be correctly installed according to the size of the monitoring space and the range of personnel activities.

All-round caring protection, real-time monitoring, abnormal alarm

The 24GHz millimeter wave radar scans the bathroom and obtains the reflected wave signal. The AI ​​algorithm extracts the characteristics of the reflected wave signal to detect heartbeat, breathing, body movement and other information. It will issue an alarm if the person stays in the bathroom for too long, has abnormal body movement reduction or disappearance, has heart rate or breathing rate outside the set range, or is restless.

Contactless health sensing devices can provide family members with no awareness, protect privacy and provide timely accident alarms, especially in private places such as bathrooms and bedrooms. They can solve the problem of elderly people being unable to call for help in accidents, and notify family members or rescue agencies as soon as possible to avoid life-threatening dangers caused by delays.
