2. Tips for buying oxygen cylinders
Look at the volume of the oxygen cylinder
The volume of the oxygen cylinder is the main factor in judging its specifications and models, and the common specifications and models of oxygen cylinders on the market are 4L, 10L, 40L and so on. Oxygen cylinders of different volumes contain different oxygen capacity, appearance height and service time, which can be considered comprehensively according to your actual situation.
4L oxygen cylinder.
【Features】The small capacity and low height design are only suitable for short-term use.
10L oxygen cylinder.
【Features】Medium capacity, moderate appearance height and service time.
40L oxygen cylinder.
【Features】Large capacity, with a high height bottle design, suitable for multiple people.
Look at the material of the oxygen cylinder
High-strength cylinders.
[Pros].High strength, corrosion resistance, long service life.
[Cons].The weight is heavier and requires regular inspection after a longer period of use.
Aluminum alloy bottles. 
[Pros].Lightweight and corrosion-resistant.
[Cons].Susceptible to impacts.
Composite bottles.
[Pros].Lightweight and explosion-proof.
[Cons].**High, susceptible to temperature changes, etc.
3. Look at the use of oxygen cylinders
Nasal oxygen cylinders.
A nasal cylinder is a device that supplies oxygen and is usually designed to be lightweight. The cap of the nasal cylinder has a switch that regulates the flow of oxygen, as well as an interface that can be connected to the nasal cannula. The attached nasal cannula is inserted into the nostrils and the oxygen flow is adjusted to continuously inhale oxygen.
【Features】It is suitable for nasal cavity without injury and good nasal ventilation.
Mask-type oxygen cylinders.
The mask of a mask oxygen cylinder is usually made of a soft material that fits snugly on everyone's face. It also has a switch on it that regulates the flow of oxygen, as well as an interface that can be attached to a mask. The interface can be connected to the output port of the oxygen cylinder, and when breathing through the mask, oxygen can be inhaled from the output port and passed through the mask to give everyone's nose and mouth.
【Features】It is suitable for Xi mouth breathing and poor nasal ventilation.
IIIThings to be aware of when using oxygen cylinders
The use of oxygen cylinders needs to be guided by professionals to ensure their safety and efficiency. The following is a brief introduction to the operation methods and precautions of oxygen cylinders
1. How to operate
First, place the oxygen cylinder vertically on a stable ground or fixed stand, making sure that the bottle does not tip over or roll.
Secondly, connect the oxygen cylinder and the pipe using the equipment, and make sure that the connection is secure to avoid air leakage or falling off.
Then, open the cylinder valve to let oxygen into the piping system. Use the adjusting screw to adjust the oxygen flow rate according to the actual needs, and observe the pressure value displayed by the high-pressure gauge at any time to ensure that the oxygen is in normal circulation.
Then, after use, close the valve of the oxygen cylinder first, and then loosen the adjusting screw, so that the oxygen in the pipeline is slowly discharged to avoid dangerous situations such as backfire.
Finally, clean the oxygen cylinders and related equipment. And place it in a ventilated, dry and clean place, avoiding direct sunlight and heavy pressure.
The steps of the above operation method are for reference only, and need to be adjusted according to the actual situation and the product manual.
2. Precautions
Oxygen cylinders should be placed vertically on the ground or on a fixed rack to avoid tilting or rolling the cylinder. When handling oxygen cylinders, care should also be taken to avoid collisions or strong vibrations on the cylinder body.
A safety check should be carried out before using the cylinder to ensure that the cylinder is not damaged or leaking. At the same time, attention should be paid to slowly opening the valve of the oxygen cylinder to avoid combustion caused by high-pressure air flow**.
The pressure in the oxygen cylinder should not exceed the specified pressure, and the change of the high-pressure gauge should be observed at all times during use. The oxygen in the cylinder should not be used up completely, a certain residual pressure needs to be retained, and the oxygen cylinder should be checked regularly for leakage or damage.
Oxygen cylinders should be kept away from fire sources and high temperature areas, and the storage environment temperature should not be too high, and at the same time, it should be avoided mixing with other gas cylinders.
If the state of the oxygen cylinder is abnormal or there are obvious uncomfortable symptoms after use, the use should be stopped immediately, and the professionals should be cooperated in time for targeted treatment.
Summary:Based on the above, there are many factors that need to be considered when purchasing an oxygen cylinder, including use, capacity, material and use method. I hope that after reading this shopping guide, it can help you and provide you with some references when choosing oxygen cylinders.
