Abstract

The invention relates to a negative pressure emergency device for airway obstruction. The negative pressure emergency device for airway obstruction comprises a handle, a piston, an air suction cylinder, protective film, an exhaust hole and a mask; the piston comprises a piston body and a connecting rod; the piston body is arranged in the air suction cylinder; the handle is arranged above the exterior of the air suction cylinder; the handle is fixedly connected with the piston body through the connecting rod; a ventilation port is formed in the middle of the top of the air suction cylinder; theprotective film is arranged at the left side of the ventilation port; the exhaust hole is formed in the right side of the ventilation port; the mask is provided with a ventilation cylinder and a gasket; the ventilation cylinder is connected with the ventilation port; the gasket is arranged around the surface of an opening of the mask. The negative pressure emergency device has the advantages of being simple in structure, convenient to use, safe, practical, suitable for being used in hospitals and at home, convenient to carry, low in cost, suitable for mass production and capable of quickly discharging foreign matter obstructing the interior of the airway.

Description

technical field [0001] The invention relates to the technical field of negative pressure first aid, in particular to a negative pressure first aid device for airway obstruction. Background technique [0002] Mechanical obstruction of the respiratory airway can be said to be the most direct and common in daily life. Therefore, the resuscitation of breathing, or tracheal foreign bodies that block the airway with foreign bodies, has attracted a lot of attention in recent years. It was previously believed that only young children could have foreign bodies in the trachea caused by improper eating. However, in today's real life, it is the foreign bodies in the trachea caused by improper eating of the elderly, which account for the highest proportion! The airway is the only way for outside air to enter and exit the body. Foreign matter absorbed into the airway by the trachea blocks the respiratory passage, causing ventilation obstruction, leading to suffocation, and even immediat...
