Description

Technical Field

[0001] This utility model belongs to the field of public safety equipment technology, specifically, it relates to a safety airbag for preventing and responding to stampede accidents in densely populated environments. Background Technology

[0002] With improved living standards, visiting tourist attractions on weekends and holidays has become a popular trend in the 21st century, leading to increasingly larger crowds. However, this overcrowding can create various safety hazards, with stampedes being the most common. Stampedes are frequent and sudden safety incidents in public places, with primary causes of death including respiratory congestion due to chest compression, cardiac arrest, and multiple organ damage. In stampedes, the dense crowds prevent chest expansion, obstructing gas exchange in the lungs and ultimately causing suffocation or cardiac arrest.

[0003] Existing public safety protection measures mainly include crowd monitoring, evacuation route planning, and emergency response plan development, but these methods are difficult to respond quickly in sudden crowding incidents. Traditional personal protective equipment (such as armor and impact-resistant vests) has problems such as being complicated to wear, lacking flexibility, and having limited protection range, and cannot meet the emergency needs in dense environments.

[0004] Therefore, there is an urgent need for a lightweight, rapidly deployable device that can provide targeted protection for the chest cavity. Utility Model Content

[0005] To address the problems in related technologies, the purpose of this utility model is to provide an anti-trampling safety airbag that achieves rapid inflation and wear through optimized structural design, effectively relieving the pressure on the chest cavity caused by crowd compression, ensuring normal respiratory function, and reducing the casualty rate in trampling accidents.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An anti-trampling safety airbag includes a wearable soft pad, an airbag body, an inflation device, and an adjustment connection device; the airbag body is distributed on the front and rear sides of the wearable soft pad, the inflation device is installed on the wearable soft pad and communicates with the airbag body, the inflation device is controlled by an inflation start device, and the adjustment connection device is located at both ends of the wearable soft pad for connecting the two ends of the wearable soft pad.

[0008] Preferably, the airbag body includes a safety airbag and small airbags, which are evenly spaced and interspersed on the wearable pad. The bottom of the safety airbag is connected to the wearable pad through a buffer connection layer, which is made of elastic mesh material to disperse the impact force and prevent the airbag from rupturing due to instantaneous compression. The airbag body is made of high-strength flexible composite material, and is flat in the uninflated state for easy carrying and storage. When inflated, it expands into a three-dimensional structure that can cover the chest cavity and upper abdominal area.

[0009] Preferably, the wearable pad is elongated and flat, and the wearable pad uses a breathable pad to improve wearing comfort.

[0010] Preferably, the adjustable connection device includes an adjustable buckle and a soft strap. The adjustable buckle is connected to the end of the wearable pad through the soft strap. The two ends of the wearable pad are fastened together by the adjustable buckle to adjust the overall tightness. The adjustable connection device is suitable for users of different body types, ensuring that the airbag fits the body and is not easily displaced.

[0011] Preferably, the inflation start device is located below the inflation start device, which includes a pull ring and a pull rope, with the pull ring connected to the pull rope and the pull rope connected to the inflation device.

[0012] Preferably, the inflation device is provided with a transparent protective cover.

[0013] Preferably, the inflation device is an air pump.

[0014] Preferably, the pull ring is covered by an inflation cap. When in use, the inflation cap is opened first, and then the pull ring is pulled. The pull ring is hidden by the inflation cap, which can prevent accidental contact with the pull ring and thus prevent inflation from starting.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model's airbag uses soft fabric, making it more comfortable and snug to wear. The safety buckle also serves to fix and adjust the size. There is a connecting buffer layer between the soft fabric and the airbag to prevent the airbag from bursting during compression, thus better protecting people's chest cavity. In the event of a sudden crowd surge, the airbag can be deployed in a timely manner, allowing people to wear the device to cope with a sudden stampede crisis. It expands the chest, allowing for free breathing and preventing cardiac arrest. The inflation cover on the chest can be quickly opened, and pulling the cord activates the air pump, causing the airbag to automatically and quickly inflate and expand, protecting the chest cavity and reducing crush injuries from crowds, thus safeguarding people's lives.
