Embodiment 1

[0047] Please see attached figure 1 , 2 , figure 1 It is a schematic diagram of the front end of a negative pressure first aid device for airway obstruction of the present invention, figure 2It is a rear end schematic diagram of a negative pressure first aid device for airway obstruction of the present invention. A pneumatic first aid device for airway obstruction, the negative pressure first aid device for airway obstruction includes a handle 1, a piston 2, an air pump 3, a protective film 4, an exhaust hole 5, and a mask 6; The piston 2 includes a plug body 21 and a connecting rod 22; the plug body 21 is arranged in the air pump 3; the handle 1 is arranged at the outer upper position of the air pump 3; between the handle 1 and the plug body 21 It is fixedly connected by the connecting rod 22; the middle position of the top of the air pump 3 is provided with a ventilation interface 31, and the two sides of the bottom are provided with supporting edges 32; the described pr...

Embodiment 2

[0051] Please see attached Figure 7 , Figure 7 It is a three-dimensional structural schematic diagram of another negative pressure first aid device for airway obstruction of the present invention. This embodiment is basically the same as Embodiment 1, the difference is that the connection between the ventilator 61 and the bottom of the mask 6 in this embodiment A fixed ring 611 is provided; the center of the fixed ring 611 is circular, surrounded by four fixed frames 612; the design of the fixed ring 611 can utilize a tie (not shown) and a fixed ring The fixing frames 612 around the 611 are connected and fixed. When carrying out first aid, by wrapping the frenulum around the sides of the patient's head and fixing it behind the head, the frenulum can be used while the silicone gasket 62 is in close contact with the patient's facial skin. The face mask 6 is fixed with the patient's face, which is convenient for emergency personnel to provide first aid, and avoids the situatio...

Embodiment 3

[0053] Please see attached Figure 8 , 9 , Figure 8 and Figure 9 They are respectively a three-dimensional structural schematic diagram of another negative pressure first aid device mask for airway obstruction of the present invention and a schematic diagram of the cooperating fixing of the buckle belt and the hole belt. This embodiment is basically the same as Embodiment 1, the difference is that, The left and right sides of mouth mask 6 body front end among the present invention are respectively provided with buckle belt 63 and hole belt 64; Described buckle belt 63 and hole belt 64 are evenly provided with a plurality of belt buckles 631 and through hole 641 respectively; The belt buckle 631 and the through hole 641 are a matching structure; the described belt 63 and hole belt 64 are provided on the left and right sides of the mouth mask 6 body. Cooperate and fix between one through hole 641, just can mouth mask 6 be fixed on the face (see Figure 9 ), and can arbitra...

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...
