It's what everyone uses abroad for babies, it's a bulb syringe. Also used for giving enemas to a constipated baby.
First time I saw one used was to clear nasal mucus build up from my baby half sister (to help ehr breathe comfortably) when she had a cold, her Mum is from Poland where ti is standard baby equipment.
The American book from the AKC on the care of Neonates advises it's use.
