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. The Oxygen flowmeter mainly consists of safety valve, flow meter, flow control valve, and humidifier bottle. 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.

First, according to the use of the scene classification

1. Oxygen flowmeter for oxygen cylinder

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. Usually used in rural hospitals, research institutions, industrial and mining sites, field hospitals, and other environments, mobility is poor. 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.

2. Wall-type oxygen flowmeter

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. It is only suitable for wards and emergency rooms in official hospitals with modern decoration design and is not mobile.

3. Portable simple oxygen flowmeter

The structure of this flowmeter is relatively simple, usually not mandatory equipped with a buoy type flowmeter that must be required to use vertically stable, but the use of mechanical valves to control the flow, and with the matching oxygen tank is usually small and easy to carry. This flowmeter is generally used for field first aid, mountain climbing, home care, and other temporary use environment.

Second, according to the method of flow control classification

1. Buoy-type oxygen flowmeter

Buoy oxygen flowmeter is divided into two types: oxygen flowmeter with oxygen cylinder and wall-type oxygen flowmeter, the main difference is that the wall oxygen flow meter does not require pressure reducing valve for pressure reduction. The principle of operation is to regulate the flow of oxygen through a flow control valve, and the flow is indicated by a buoy in a flow meter. This is the most commonly used oxygen flow meter in hospitals, with mature technology and reliable quality.

 

2. Turntable oxygen flowmeter

The rotary dial oxygen flowmeter is adjusted by the flow control valve knob, and the flow rate is directly displayed by the indicator. It is relatively simple in structure, but when the pressure inside the oxygen cylinder varies greatly, it is easy to affect the accuracy of the display.

In summary, flowmeter is used to measure the flow of liquid or gas, medical oxygen flow meter is dedicated to measuring medical oxygen flowmeter, the role is to ensure that oxygen is inhaled by the human body in a suitable flow band. You can choose your own suitable products according to the classification.
