1, medical equipment companies
Medical equipment companies generally in the sale of medical equipment and appliances more, and not all medical equipment companies sell medical oxygen. The reason is that medical oxygen is usually stored as liquid oxygen, which needs to be stored separately for safety reasons and involves the evaporation of liquid oxygen during storage.
So, only some want to expand their business, or the surrounding really have the need, and the demand is still relatively large medical equipment companies will have to sell, but these companies are liquid oxygen to sell, the price and quality is still to be proved.
2, hospital
General family oxygen, in the case of oxygen is not big, you can choose to go to the hospital to buy, the hospital supply of oxygen purity is more guaranteed, but the hospital's oxygen is generally mainly used to treat the patient's disease, there will not be too many sales.
So, if the demand is large, you may not be able to buy too much, and the hospital's oxygen will be relatively expensive to buy, after all, these medical oxygen is not specifically for sale.
3, liquid oxygen manufacturers
Liquid oxygen manufacturers are the main production of liquid oxygen, medical oxygen ownership is also relatively high, so whether it is for home use or in the hospital, whether it is a large or small demand, can choose, is compared to the first two more appropriate way.
But when buying, you still need to pay attention to oxygen purity and other issues, to avoid some manufacturers to cut costs, the quality of the oxygen sales to customers, so the direct result is to affect our health.
Oxygen cylinders safe use:
Oxygen cylinders are special high-pressure containers for the storage and transportation of oxygen, which are made up of four parts: the bottle, the hoop, the valve and the cap.
There are two anti-vibration rubber rings on the outside of the cylinder, the bottle is sky blue, and marked with black paint, "oxygen" two words, to distinguish other cylinders.
Oxygen is widely used in welding and cutting as an ideal combustion gas.
Because the oxygen cylinder is a kind of mobile container of compressed gas, high pressure, frequent loading and unloading transportation, the use of the environment is messy, often make the use of oxygen cylinders in the state of insecurity, once the explosion of the cylinder, will cause great losses to the people's lives and property.
