Embodiment Construction

[0027] Such as figure 1 As shown, the outer layer mask 14 of the gas mask for first aid of the present invention is a transparent cover body, the edge of the outer layer mask 14 is connected with a mask ring frame 16, and the bottom of the outer layer mask 14 is buckled with an air outlet net cover 10. The inner layer nose and mouth cover 15 that front end is closed, rear end opening is connected with outer layer mask 14 inner bottom surface, and its rear end opening can cover people's mouth and nose, forms breathing cavity. One-way inhalation valves 3 are respectively arranged on the two sides of the inner layer nose and mouth mask 15 and the positions corresponding to the nostrils, and one-way exhalation valves 11 are arranged on the bottom of the inner layer nose and nose mask 15, and the exhaled gas passes through the exhalation valve. The air outlet grille 10 of the valve 11 and the outer layer enters the atmosphere.

Abstract

The invention relates to a first-aid anti-gas mask which structurally comprises an outer-layer face mask and an inner-layer mouth nose mask, wherein a forehead protecting edge and a head strap are connected with a face mask annular frame at an edge of the outer-layer face mask; a moveable inhaling opening and a moveable exhaling opening are arranged on the inner-layer mouth nose mask; matching ports are respectively arranged on two sides of the outer-layer face mask; a miniature oxygen bottle is connected with at least one of the matching ports through a fixing connector; an air outlet and an airflow adjustor are connected with a sealing cover of the miniature oxygen bottle; a drug atomizer is connected with the fixing connector; and a communicating pipe is connected between the air outlet on the sealing cover and the drug atomizer, so that oxygen in the miniature oxygen bottle can enter into a face mask cavity of the anti-gas mask through an airflow channel in the sealing cover, the airflow adjustor, the communicating pipe, the drug atomizer and the fixing connector. The first-aid anti-gas mask can be used for timely supplying oxygen to the wounded people on an emergency site, so as to improve the in-vivo anoxic state of the wounded people, reduce the hurt degree and increase the cure rate.

Description

technical field [0001] The invention relates to a gas mask, in particular to a gas mask for first aid. Background technique [0002] First aid gas masks are mainly used in chemical warfare and public emergencies. In the occasions where chemical warfare agents are released and toxic chemical gases leak, it will cause the on-site personnel to be poisoned by inhaling toxic gases. If the on-site emergency oxygen supply is timely, it can well solve the problem of human poisoning caused by leakage of chemical warfare agents and toxic chemical gases, resulting in human hypoxia and life-threatening problems. Emergency oxygen supply can increase the arterial blood oxygen partial pressure and oxygen saturation level of poisoned patients by increasing oxygen concentration and oxygen flow rate, promote metabolism, reduce hypoxic symptoms, control the further development of the disease, and provide rescue and treatment for the poisoned wounded in the rear hospital. Treatment buys time ...
