This type of flowmeter is connected to the low pressure oxygen delivery port installed on the wall, so there is no need for a pressure reducing valve. This environment is characterized by relatively fixed use locations and relatively large demand for oxygen, so it will be equipped with sizeable medical oxygen cylinders of large size, capacity, and weight, which are inconvenient to move. Usually used in rural hospitals, research institutions, industrial and mining sites, field hospitals, and other environments, mobility is poor. This kind of flowmeter is connected to high pressure oxygen cylinder, it needs a pressure reducing valve to change the high pressure oxygen into low pressure oxygen, and then for the patient to use it. First, according to the use of the scene classification 1.
Oxygen enters the humidification bottle through the flow meter and is outputted according to the constant flow value after humidification treatment for the patient to inhale oxygen, the flow rate is adjusted through the flow controller, and the following is the classification of the oxygen flowmeter. The Oxygen flowmeter mainly consists of safety valve, flow meter, flow control valve, and humidifier bottle. Oxygen flowmeter is a medical device used for oxygen flow measurement in hospitals, its main function is to give oxygen to emergency patients and oxygen to hypoxic patients at a suitable flow rate.
