1. Safety: Oxygen is the gas supporting combustion, and the negative pressure suction pipe may generate sparks or static electricity. If they are too close, there is a potential danger of fire or explosion. Therefore, in order to ensure the safety of use, we should try to keep a certain distance.
2. Avoid interference: Both the oxygen tube and the negative pressure suction tube belong to medical devices, which may cause some noise, vibration or electromagnetic interference during operation. If they are too close, they may interfere with each other and affect the normal operation of the equipment and the accuracy of the measurement results.
3. Pipe confusion: oxygen pipes and negative pressure suction pipes are usually distinguished by different colors or signs. Keeping a certain distance can avoid pipeline confusion and facilitate operators to use and manage these equipment correctly.
