Project Description

Nasal congestion is a common problem for infants and young children due to colds, allergy, infection and teething. Physicians usually suggest that nasal secretions be removed to avoid infection that may affect sinus and if left untreated may spread further infection to the ears and lungs.

There are three types of nasal aspirator available in the market: bulb syringe, powered device and mouthpiece suction. However all of these devices have limitations such as not easy to clean, weak suction, bulky and noisy.

The invented device is based on a patented vortex generating nozzle that can generate significant spiral flow and enough negative pressure to be used as suction device.

Suction is achieved simply by blowing air tangentially into the nozzle. Here, we can eliminate the potential for the mucus to travel to the mouthpiece and at the same time blowing is easier than sucking action.

Features and Benefits

  • Quick relief from blocked nose for infants and toddlers.
  • Unique blowing action to clear the nose congestion.
  • No potential route for mucus to flow to your mouth.
  • Can be easily cleaned.
  • Controlled suction.
  • Compact and quiet operation.

Market Value and Size

In 2011, there were about 1.4 million children under the age of four in Australia.

Assuming a price of $15 per unit, this equates to $21 million market. Globally it can scale up to $5-8 billion market.

Potential Application and Market Opportunities

This invention can provide quick relief for infants and toddlers from blocked nose. The unit will be designed to be compact for traveling and easy to clean.

Development Stage

Early prototype has shown good potential for this device to be used as nasal aspirator. We are in the process of improving the suction and ergonomics of the device.

Industry collaborator is invited to commercialise this device.
