1. Confirm the connection: Check whether the infusion bag is properly connected to the infusion system. Ensure that the infusion lines are tightly connected, without air leakage and loose joints.
2. Check the liquid flow: observe the liquid flow in the infusion line. If the infusion system is normal, the liquid should flow from the container into the infusion bag and reach the target position through the infusion pipe. If there is no liquid flow, please contact a medical professional or relevant medical service department for troubleshooting and maintenance. It is important to remember that problems involving infusion should be handled by medical professionals or relevant medical service departments. They have professional knowledge and skills, and can correctly operate and handle infusion equipment to ensure the safety and effectiveness of infusion process. Don't try to handle the problems involving infusion yourself, so as not to cause unnecessary risks and injuries.
