Multifunctional safety protection waistcoat

Abstract

The invention discloses a multifunctional safety protection waistcoat. The multifunctional safety protection waistcoat comprises a waistcoat body, a sensing unit arranged on the waistcoat body, and a safety air bag unit arranged in an inner cavity of the waistcoat body, wherein the sensing unit comprises multiple collision prediction sensors, a movement sensor, a physical sign monitoring sensor, a waistcoat tension sensor and a control unit connected with all the sensors, the safety air bag unit comprises a safety air bag, an air generator acting on the safety air bag, and an igniter used for starting the air generator, and the igniter is connected with the control unit. According to the multifunctional safety protection waistcoat, when the head, hip and body of a user suffer from collision or external pressure, the safety air bag can be opened in time to surround the collided part instantly, and then the user is protected from injuries.

Description

technical field [0001] The invention relates to a safety protection vest, in particular to a safety protection vest suitable for the elderly. Background technique [0002] As the trend of population aging is accelerating, the elderly population is increasing, and there are many security management issues for the elderly. The safety management of the elderly has also become an issue of increasing concern to the society. In response to the needs of personnel access management, intelligent areas, and help alarms in large public places such as nursing homes, there are currently various types of solutions on the market, from the initial GPS positioning management, mobile phone positioning management, and later. Passive RFID and active RFID wireless radio frequency management systems have improved the management level of nursing homes and the elderly to varying degrees. Although the safety issues of the elderly have been effectively resolved, problems still exist, such as How to...

Problems solved by technology

At present, there are not many researches at home and abroad on the detection of pre-fall hazard information used to prevent falls and reduce the damage caused by falls, and commercial products have not yet appeared. few

In 2007, based on the inspiration of airbags in automobile accident protection, scholars such as Tamura and Yoshimura in Japan began to consider finding out the dangerous state of the elderly before they fell, so as to allow time to activate the airbags to reduce the impact on the body when the elderly fell. They only used a three-axis acceleration sensor. After experiments and statistical analysis, it was determined that when the acceleration reached a certain threshold, it was judged as a free fall state, so a margin of nearly 300ms was guaranteed before the maximum impact came. For protection measures, of course, due to the single sensory information collected, there are great flaws in the solution to the problem of misjudgment in the experiment

In 2008, the Japanese Prop company also launched a wearable air bag (Japan Information Network), which can complete the inflation task within 100ms to protect the head and buttocks; but it needs to be opened manually, which is not conducive to protecting the elderly

But the outer shell is hard enough only to guarantee that it will not break, but its ability to cushion the impact has not improved
