Developed for the special needs of newborns, infants and small children, the Oricom HNA300’s features are designed to make breathing easier by providing a fast, efficient way to clear the mucus from a baby’s nasal passages. There are two main points of difference with this model vs the others you will see on the market; The HNA300 has a rechargeable built in battery. Do away with replacing batteries or never having one when you need it! Simply charge it up and you are good to go. This unit is quiet and unsuspecting newborns will be more at ease with a quiet motor then other products that will startle and unsettle a newborn. Probably the most important point – the HNA300 is included as a medical device on the Australian Register of Therapeutic Goods (ARTG 307470).
