A buried self-rescue auxiliary breathing assembly

Abstract

The invention relates to a buried self-helping respiring assistance assembly. The assembly comprises a protecting helmet and a protecting suit, a transition protecting layer is arranged in the circumferential edge of the protective helmet, the transition protecting layer is made from transparent materials, the upper end of the transition protecting layer is connected with a helmet body, the lowerend of the transition protecting layer is connected with a retracting sleeve member, the retracting sleeve member comprises an annular retracting airbag, an inflation pump and an inflation pipeline, and the inflation pump is connected with the annular retracting airbag through the inflation pipeline; a protecting effect can be achieved by the transition protecting layer on the helmet to prevent the mouth and the nose from being buried by soil and dust, the effects of inflating and retracting can be achieved by the retracting structure to ensure that an independent space can be formed in the assembly, the effect of buffering protecting can be achieved by an air collecting device, more importantly, air in the air collecting device can be provided for a person suffering from disaster, so thata respiring function is achieved, and the oxygen supplying of a user is ensured.

Description

technical field [0001] The invention relates to a survival device, more specifically, to a buried self-rescue auxiliary breathing assembly. Background technique [0002] Earthquakes, also known as ground motions and ground vibrations, are vibrations caused by the rapid release of energy from the earth's crust, during which seismic waves are generated. Earth's plates are squeezed and collided with each other, causing dislocation and rupture at the edge of the plates and inside the plates, which is the main cause of earthquakes. [0003] Debris flow refers to a special torrent carrying a large amount of sediment and stones due to landslides caused by heavy rain, snowstorm or other natural disasters in mountainous areas or other areas with deep valleys and steep terrain. Debris flow has the characteristics of suddenness, fast flow rate, large flow rate, large material capacity and strong destructive force. Debris flows often destroy highways, railways and other transportation...

Problems solved by technology

[0005] The occurrence of the above disasters may lead to the danger of the victims being buried, and once buried, the key to real-time short-term rescue is to provide enough oxygen. Generally, if the mouth and nose are buried, the victims will be buried Immediate suffocation within a period of time, extremely dangerous
