CPAP (continuous positive airway pressure) oxygen supply

The utility model discloses a CPAP (continuous positive airway pressure) oxygen supply. The CPAP oxygen supply is characterized by comprising a three-way elbow (1), an air sac (4), a connecting tube (5) and a pressure stabilizing bottle (10). The three-way elbow (1) comprises an oxygen supply connector (2) which is a threaded connector, a pressure stabilizing connector 93) and a pulmonary ventilation connector. The three-way connector (1) is connected with the air sac (4), the connecting tube (5) and the pressure stabilizing bottle (10) in order through the pressure stabilizing connector (3). The oxygen supply connector (2) is externally connected with an oxygen supply source. The CPAP oxygen supply is simple in structure and reasonable in design; the technical problem that a pressure meter of the existing CPAP oxygen supply may fail, causing safety hazards, is solved; the CPAP oxygen supply is low in manufacturing cost and good in service effect, has good market prospect and good economic and social benefits.
