Simple respirator is used for cardiopulmonary resuscitation and artificial respiration first aid. It is easy to use, has less radiation symptoms, is easy to carry, and can be ventilated immediately with or without oxygen source

usage method:

When the sphere is squeezed, positive pressure is generated, the inlet valve is closed, the internal gas pushes the duckbill valve to open, and the outlet valve is blocked. The gas in the sphere is sent to the sick population by the duckbill valve. If oxygen is used, oxygen is in the sphere, and the oxygen in the sphere is squeezed into the sick population

Loosen the squeeze ball, push the oxygen valve upward, and return to the closed state, so that the gas exhaled by the patient is discharged from the outlet. At the same time, the air inlet is subject to the negative pressure of the ball, open the air inlet valve, and the oxygen in the air bag is sent to the ball until the ball is completely restored to the original state of extrusion
