secondly, the hand-pressed rubber ball 9 is held by an emergency worker, the air inlet is attached to the palm, pressure is regularly applied to and released from the hand-pressed rubber ball 9, outside air enters the hand-pressed rubber ball 9, then the air is disinfected and oxygenated by the oxygenation and detoxification device, and the oxygenation agent reacts with carbon dioxide in the air to generate oxygen to achieve oxygenation; oxygen is also generated through the reaction with moisture in the air, so that the oxygen increasing function is realized; the metal cotton can filter dust or impurities in the air, the filtered and oxygenated air continuously enters the ejection and suction air supply valve 5 along the air supply connecting pipe 8 and the one-way valve 6 and then is sent into the mouth of a patient through the breathing ejector 3, and as the ejection and suction air supply valve 5 adopts a plurality of ejection and suction hole structures, the air uniformly and smoothly enters the mouth of the patient and enters the lung, and then the exchanged air is exhaled through the nostrils, thus realizing the effect of emergency treatment of the patient through continuous circulation; at the moment, the patient can be carried while rescuing, and when the carrying condition can meet normal rescue, the on-site first aid can be converted into normal rescue; at the moment, the other end of the bidirectional air inlet channel 5.2 of the ejection and suction air supply valve 5 is connected to an air bottle 11 through an air supply connecting pipe 8, an electromagnetic switch valve 10 is connected to the air supply connecting pipe 8, and the electromagnetic switch valve 10 is connected with a controller 13 through a signal wire 12 to realize oxygen delivery to a patient; the connected oxygen-increasing and toxicity-removing device and the hand-pressed rubber ball 9 are directly taken down.
Example 3, the difference of the invention from example 2 is: the oxygen increasing agent adopts potassium peroxide, and the chemical reaction is as follows:
2K2O2+2CO2=2K2CO3+3O2
2K2O2ten 2H2O =4KOH ten O2↑
Therefore, in an inflammable, explosive and toxic environment, the oxygen supply to the patient is increased, the first-aid efficiency is improved, and the first-aid of the patient is realized; and the moisture is eliminated, and impurities or particles in the air are filtered through the metal cotton.
The above description is only a few of the preferred embodiments of the present invention, and any person skilled in the art may modify the above-described embodiments or modify them into equivalent ones. Therefore, any simple modifications or equivalent substitutions made in accordance with the technical solution of the present invention are within the scope of the claims of the present invention.
