Description
Technical Field
The invention relates to the technical field of nursing instruments, in particular to an old man bathing anti-falling power assisting device.
Background
The world health organization reports that 30 or more thousands of people die from falls worldwide each year, half of which are older than 60 years. One of the highest incidence of accidents in the elderly is falls. According to the statistics of the world health organization, the fall is the leading cause of the casualties of the old aged over 65 years old. The potential threat of falling is not inferior to heart disease, stroke attacks, for the elderly. Falls can lead to a significant deterioration in the health status of the elderly, as well as disabilities, mental and psychological deterioration, to death, and significant medical cost burden on the elderly and family members. In fact, the most important place where elderly people fall is not a public place, but a home, especially a bath room. This is mainly because:
(1) the old people are easy to have poor physical strength due to the fact that the bathing time is too long, and the joints are not flexible, so that the old people fall down;
(2) when the bath is taken, the increased hot water vapor in the bathroom can expand the cerebral vessels of the old and accelerate the blood flow, thereby causing insufficient blood supply to the brain and causing faint;
(3) because the bathroom space is relatively small, the old is in a closed space when taking a bath, because the oxygen in the bathroom is less due to the increase of water vapor, and the air circulation is relatively poor, the old can fall down due to oxygen deficiency.
According to the research on the aged market and the development trend research report of the aged population in China in 2019 and 2025 published by the intelligent research and consultation network, China begins to step into the aged society along with the initial formation of the aged age structure. In 2020, the elderly population in China is expected to break through 2.5 hundred million people, and the proportion of the population over 60 years old to the total population reaches 17.17 percent. It is expected that in 2025, the population over 60 will break through 3 billion people, and china will become an ultra-old country. However, according to investigation, no anti-falling and power assisting device for bathing in a bathroom of the old people is available on the market at present, so that a bathing anti-falling and power assisting device suitable for the old people is urgently needed in the society in order to deal with the coming aging society.
