The Bubble Humidifier Jar is a crucial accessory in medical oxygen therapy 

systems. This device is primarily connected between the oxygen concentrator, 

central oxygen supply system, or gas source and the patient's oxygen delivery 

circuit. Its core function is to humidify dry medical oxygen and intuitively monitor 

oxygen flow by observing the dynamics of bubbles in the jar, thereby ensuring 

the comfort of the patient's respiratory tract and the safety of treatment.
