1. How to use oxygen tanks
Oxygen tanks, also called oxygen bottles, are high-pressure containers used to store and transport oxygen. They are used in hospitals, first aid stations, and nursing homes. It is an ideal oxygen supply equipment for supplementing oxygen in various hypoxic environments. The correct way to use oxygen bottles is:
1. Before use, the reserve should be checked. If medical oxygen is needed, You must go to a legal medical oxygen station to refill oxygen, and carefully check whether oxygen inhalation tubes, humidifiers, etc. are clean.
2. Slowly open the gas cylinder valve. The pressure indication is within the normal range (13.3-15Mpa). At this time, the regulating valve is closed.
3. According to the mark on the upper part of the humidifier, connect the oxygen outlet pipe of the oxygen supplier to the oxygen supply nozzle of the humidifier, and connect the oxygen suction pipe to the oxygen outlet nozzle of the humidifier.
4. Slowly open the switch of the medical oxygen bottle, adjust to the appropriate flow rate as needed, and then insert the oxygen nasal plug into the nasal vestibule to inhale oxygen.
5. After oxygen inhalation, you should first pull out the nasal plug, turn off the switch, and then close the flow regulating valve when the pressure drops to 0Mp.
2. Precautions for the use of oxygen tanks
1. When transporting oxygen bottles, avoid tipping and collision to prevent explosion, because the oxygen in the oxygen bottle is based on 14.71 MPa is poured in, the pressure is very high.
2. Oxygen bottles should be placed in a cool place. Fireworks and flammable materials are strictly prohibited around the bottle. They should be at least 5m away from the stove and 1m away from the heater; the distance from the open flame should generally not be less than 10 meters.
3. Avoid exposure to the sun when using in summer. Because the capacity of the oxygen bottle is limited, exposure to the sun will increase the temperature of the medium in the bottle, causing a sudden increase in pressure inside the bottle, putting the oxygen bottle in a dangerous state.
4. In winter, when the pressure reducer and piping system of the oxygen cylinder freeze, it is strictly forbidden to bake it with fire or slam the cylinder with something like iron, let alone tighten the adjustment of the pressure reducing gauge. Screws to prevent oxygen from suddenly rushing out in large quantities and causing accidents.
5. Do not apply oil on the oxygen meter and the screw port, and do not use oily hands to load or remove it to avoid burning.
6. When stopping oxygen, you should first remove the tube and then turn off the oxygen switch; when changing the oxygen flow rate midway, you should first separate the oxygen tube and the oxygen suction tube, adjust the oxygen flow rate, and then connect them. To avoid turning on the wrong switch, a large amount of gas suddenly rushes into the respiratory tract and damages the lung tissue.
7. Do not use up all the oxygen in the oxygen bottle. When the pressure gauge pointer drops below 0.3MPa, it can no longer be used to prevent dust from entering and causing an explosion when it is re-inflated. Users are strictly prohibited from filling oxygen without permission.
8. Used empty oxygenCylinders should be hung with an “empty” sign to facilitate timely replacement of oxygen cylinders, so as to avoid affecting the speed of rescue due to moving the wrong oxygen cylinder in an emergency.
9. If air leakage is found during use, please close the gas cylinder valve immediately.
10. Medical oxygen tanks should be inspected every three years. The purpose is to promptly check the safety status of the oxygen tanks and discover defects and hidden dangers in a timely manner to avoid accidents.
3. How long can a can of oxygen cylinder be used?
How long a can of medical oxygen cylinder can be used depends on the capacity of the oxygen cylinder and the oxygen inhalation Flow, taking a common 10L volume medical oxygen cylinder as an example. The filled cylinder has about 135~150 atmospheres of pressure, and the oxygen storage capacity is about 1350~1500L. If the oxygen inhalation flow is 2L/Min, more than ten About hours.
Warm reminder: Do not use up all the oxygen in the oxygen bottle to prevent dust from entering and affecting the next use.
