Instruction manual:
Before each use, unfold the aspirator and wash it with warm water, then put a small piece of cotton on the part of the aspirator connected to the tube. Put a few drops of saline solution into the baby's nostril, wait 10 to 20 seconds and then gently pull the mouth to aspirate the secretion from the nostril with a pump.
Do not put the aspirator in hot water or a microwave oven. Rinse with warm water and in the unfolded state.
