The configuration of the oxygen cylinder trachea needs to be selected based on the specifications and purpose of the oxygen cylinder. For example, common oxygen cylinder specifications include 4 liters, 8 liters, 10 liters, 15 liters, and 40 liters, and different specifications of oxygen cylinders need to be matched with corresponding connecting pipes.
1. Select based on tracheal specifications:
The specifications of oxygen pipes mainly depend on the diameter, working pressure, and material. Common pipe diameters include 6mm, 8mm, 10mm, etc. The working pressure is generally 0.5MPa, 1.0MPa, 1.5MPa, and the material is mostly rubber or plastic. According to regulations, the oxygen hose is blue, with a working pressure of 1.5MPa, an inner diameter of 8mm, and an outer diameter of 18mm.
2. Connection method of trachea:
Installation of pressure reducer: Install the pressure reducer on the oxygen cylinder, ensuring that the nut is in close contact with the cylinder valve and tighten it securely
Connecting the trachea: Connect one end of the oxygen tube to the outlet of the pressure reducer, and the other end to an oxygen inhalation device (such as a nasal cannula or mask)
Check air tightness: Apply soapy water to all interfaces and observe for any bubbles to ensure no leakage
Adjust flow: Adjust the flow adjustment knob on the pressure reducer according to the demand. Generally, medical oxygen is 0.2-0.5MPa.
3. Precautions:
Oxygen and acetylene pipes must not be mixed. Oxygen hoses are blue and acetylene hoses are red
Before use, check whether the trachea is damaged, aged, or cracked.
The length of the trachea should not be too long, generally not exceeding 20 meters, to avoid pressure loss
All connections must be well sealed to prevent oxygen leakage
