Portable fall protector

Abstract

The invention relates to a portable fall protector which comprises a belt, an air sac and a fast inflation starter. The belt is provided with an opening, and the air sac is folded in the opening. The fast inflation starter is connected to an air inlet of the air sac through an air guide tube and comprises an air cylinder, an electromagnetic valve, a sensor module, a processing module, and a drive module, wherein one end of the electromagnetic valve is connected to the air cylinder, the other end of the electromagnetic valve is connected to the air guide tube, the sensor module is used for acquiring body pre-fall information, the processing module is electrically connected to the sensor module and is used for receiving the body pre-fall information and processes the body pre-fall information to judge whether a human is about to fall or not, and the drive module is electrically connected to the processing module and the electromagnetic valve and is used for driving start of the electromagnetic valve and a power supply according to control commands from the processing module. The portable fall protector is capable of judging fall of the human body accurately, the air sac expands quickly in case of falling of the human body so as to buffer between human hip bone and ground, and accordingly the human hip bone is protected effectively.

Description

technical field [0001] The invention relates to a health protection device, in particular to a portable fall protection device. Background technique [0002] 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 the elderly, seriously affecting the health and independent living ability of the elderly, and causing psychological stress and fear in 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 located only su...

Problems solved by technology

[0003] At present, fall protection devices generally use wearable devices, which must be worn on the body. In winter, the elderly wear more clothes, and the fixed underwear will cause inconvenience to the elderly. In summer, it will be stuffy and the comfort will not be obtained. Guaranteed, it is inconvenient for the elderly to wear for a long time due to nursing obstacles of urinary incontinence patients; for the human body protection devices using airbags, they are all designed so that the upper body of the human body can lie on the airbag after a fall, which requires a larger airbag, However, a larger airbag means a larger volume and mass, which will inevitably bring inconvenience or burden to the elderly who are inconvenient to move and have weak constitutions. Moreover, after a human body falls, the hip bone is usually the first to be injured. Ground, the hip bone is most vulnerable to injury, and hip bone fractures often occur. However, most of the current airbags focus on the protection of falling directly behind. The most common problem; at the same time, most of the current fall judgment devices mainly rely on acceleration to judge the occurrence of a fall event, but the human body movement is very complicated, and the reliability of predicting the fall by relying on less or a single human body movement posture information is not high. When the human body falls and cannot be judged, it will not have a protective effect. When the human body does not fall and makes a wrong judgment, it will inevitably bring inconvenience to the wearer
