Working principle:
Respiratory airflow alternately run for the positive and negtive pressure, breathing resistance is small, pressure reducer, counterflow.
Assembling of oxygen for quantitative oxygen vavle, atomatic supply vavle, manual supply vavles, pressure reducing vavles, safety valves, emergency switch focus to design into one, compact, easy disassembly and maintenance.
Equipped with a row of saliva in the mouth with the pump, the saliva can always be ruled out.
