Background technique

With the growth of age and the aging of the body, the life and health of people, especially the elderly, will be seriously affected, and falling is one of the "culprits". A fall is defined as a sudden, involuntary, involuntary change in position, falling onto the ground or a lower surface than the initial position. Falls are very common among older adults,

It has seriously affected the health and independent living ability of the elderly, and caused the psychological pressure and fear of the elderly. Falls often cause great damage to the body of the elderly, and sometimes the consequences are even fatal for the elderly. According to statistics, 90% of hip fractures are caused by falls. Hip fractures mainly include femoral fractures and intertrochanteric fractures. In humans, the greater trochanter of the femur is only located subcutaneously on the posterolateral side of the buttocks, lacking soft tissue protection, and is rectangular in shape. There is no structural attachment behind it, and it is located in the posterior upper part of the femoral neck. The location of the greater trochanter is superficial, so there is a greater chance of fractures caused by direct violence. When the elderly fall on the side and the rear, one hip often touches the ground first, and the thigh is adducted at the same time. At this time, the greater trochanter will be more prominent. Due to the lack of soft tissue cushioning in this area, the greater trochanter area of the femur will directly contact the ground with force, resulting in an intertrochanteric fracture. Because the femoral neck has an anteversion angle of 12-15 degrees forward, if the force of the greater trochanter of the femur is extensive and no trochanteric fracture occurs during a fall, the violence will be transmitted upward along the femoral neck, and the gravity of the upper body and the impact of the ground will be in the A shear force is formed at the femoral neck, resulting in femoral neck fractures, especially in elderly people with osteoporosis who are prone to such fractures.

Hip protectors are fixed on the underwear of the hip and must be worn on the body. The elderly wear more clothes in winter, and fixing them in the underwear will cause inconvenience to the elderly. In summer, it will be stuffy and the comfort cannot be guaranteed. It is even more inconvenient for the elderly to wear long-term wear due to the nursing obstacles of urinary incontinence patients; the airbag-based body protection devices are designed so that the upper body of the human body can lie on the airbag after a fall, which requires a larger airbag, but the airbag Larger means that there will be larger volume and quality, which will inevitably bring inconvenience or burden to the elderly with inconvenient mobility and weak constitution.
