Description

Falling-prevention wound air bag

Technical Field

The invention relates to the technical field of protective equipment, in particular to an air bag for preventing falling and trauma.

Background

With the rapid increase of the population of the elderly, the aging problem becomes the most prominent problem in the current society. Currently, the world-wide aged population over 60 years of age is over 6 billion. The aging situation of the population is more severe, and three new characteristics of aging, aging and empty nestification are presented to accelerate the development.

Falling is a serious problem for the aged people, the probability of falling is much higher for the aged people than for the young people, and besides the injuries on limbs, serious sequelae can also be caused in psychology and social life after falling.

Statistically, about 424000 deaths each year in the world are directly related to fall behavior, and falls are the second leading cause of accidental death in the world (second only to traffic accidents). Studies have shown that in older adults aged 65 years old, the rate of 1 or more fall experiences per year is as high as 1/3, with 20-30% of the elderly causing bruising, hip fractures, head trauma, etc. in the event of a fall and increasing with age. The total medical cost for falls in the united states is over $ 200 billion per year. At present, about 1.3 million old people exist in China, about 2000 million old people happen 2500 tumble accidents each year, and the direct medical cost exceeds 50 million yuan RMB. Therefore, the falling down becomes an important factor which threatens the life safety of the old and increases the social burden. Meanwhile, the body imbalance caused by some diseases is easy to fall down. In the face of the situation, the development of the intelligent falling detection and protection system has positive practical significance.

Chinese patent CN201609141U discloses a "fall protection device", which comprises: helmets and alarm devices; wherein the helmet is an inflatable helmet composed of an air bag, and the alarm device is arranged in the air bag of the helmet. The alarm device starts alarm prompt through pressure change of people falling detected by the pressure sensor, and the alarm device has the functions of preventing falling and injury and calling people for rescue. The device focuses on protecting the head of a human body, but cannot effectively protect the head of the human body from injury such as hip fracture caused by falling.

The falling-prevention wound air bag is composed of four air bags, namely a front air bag, a rear air bag, a left air bag, a right air bag and a right air bag, wherein the three wires are connected with the air bags, when the user falls suddenly, the user presses a switch button to automatically ignite, the four air bags can be opened simultaneously to. Meanwhile, the falling-prevention wound air bag is safe, reliable and practical, is suitable for being carried by each elderly who acts for self-care, and has a sense of safety.
