Atmospheric oxygen therapy includes oxygen storage oxygen therapy that uses oxygen cylinders or rubber oxygen bags and oxygen generation oxygen therapy that uses various oxygen generation equipment.
Use high-pressure resistant cylinders to fill the oxygen produced in the factory for storage, which is a common source of oxygen for oxygen therapy. The small oxygen cylinders commonly used in households have a volume of 1 to 2 liters and a weight of about 3 kg. It can also be made of aluminum alloy and other materials. When in use, oxygen must pass through the decompression device, flow regulator and humidification device. After the oxygen is humidified, it is mixed with a certain amount of moisture, which can avoid dehydration of the respiratory mucosa due to inhalation of dry gas.
Steel cylinders for storing and transporting oxygen generally have a maximum working pressure of 150 kg per square centimeter, which is a high-pressure vessel, and the withstand pressure should reach 300 kg per square centimeter to ensure safety. If the cylinder itself does not meet the technical requirements, or if the correct methods are not followed during transportation, storage and use, combustion and explosion may occur.
The oxygen cylinder should be painted sky blue and marked with the words "oxygen" (normal oxygen) or "medical oxygen" in black. On the shoulder of the oxygen cylinder, there should be a steel stamp mark of the manufacturer and inspection unit. The content of the steel stamp includes: the name or code of the manufacturer, the number of the cylinder, the weight of the cylinder in kilograms (M), the working pressure of the cylinder (P), the volume of the cylinder (V) and the date of manufacture.
According to regulations, the maximum service life of steel cylinders is 30 years. Steel cylinders shall be inspected and appraised by a special inspection unit every 3 years, and the steel seal shall be marked after appraisal. The steel stamp of the inspection unit includes: inspection unit code, inspection date and next inspection date, indicating that the bottle body has a defect and the working pressure must be reduced. The word "drop" and the allowable working pressure (P), and those that should be scrapped are marked with " The word "waste". All cylinders with wrong color or words, with incomplete or unrecognizable steel stamps. Exceeding the service life or inspection period, the cylinder valve is skewed, cracked or damaged, the surface is damaged or rusted with a depth of 2 mm and an area of 1 square centimeter, and the knocking sound is not clear, all belong to the dangerous cylinder. use.
There should be two shockproof rubber rings on the outside of the cylinder. During transportation, handling and storage, prevent sunlight exposure, keep away from heat sources, and keep the cylinder temperature below 40°C. The distance between the oxygen cylinder and the open flame should not be less than 10 meters. To prevent the cylinder from falling or being hit. The room where oxygen is used should be well ventilated and smoking is prohibited. The valves, decompression gauges, hoses and other parts that come into contact with oxygen must not be contaminated with the slightest greasy dirt. In order to facilitate carrying, the high-pressure oxygen stored in the steel cylinder is often refilled into a small oxygen bag. The oxygen bag is made of canvas covered with rubber.
Oxygen storage in steel cylinders and oxygen storage in rubber bags have to be filled repeatedly, which is very inconvenient for users who are far away from oxygen factories or oxygen stations. The rubber bag has no storage safety problem, but it can only be used for about 20 minutes. There is a chronic leakage during storage, the stored oxygen is contaminated by the volatilization of rubber materials (pungent rubber smell), and generally there is no humidifying device, which is a last resort.
Our oxygen concentrators are more convenient, simple and safe to use.
