The FlexFit Nasal Cannula employs a flexible septum hugging set of flow ports (prongs) to accomplish a snug and comfortable fit for any patient.

The FlexFit Nasal Cannula addresses a common problem, encountered usually by eldrely patients that are on a prescribed regimine of oxygen therapy. A large number of these patients experience dislodging of their nasal cannula multiple time daily.

The FlexFit Nasal Cannula will ensure that all oxygen therapy patients can experience an uninterrupted flow of their prescribed O2 levels.

**The nasal cannula (NC) is a device used to deliver supplemental oxygen or airflow to a patient or person in need of respiratory help. This device consists of a plastic tube which fits behind the ears, and a set of two prongs which are placed in the nostrils. Oxygen flows from these prongs. The nasal cannula is connected to an oxygen tank, a portable oxygen generator, or a wall connection in a hospital via a flowmeter. The nasal cannula carries 1–5 litres of oxygen per minute. There are also infant or neonatal nasal cannulas which carry less than one litre per minute; these also have smaller prongs. The oxygen fraction provided to the patient ranges roughly from 24% to 35%, or the cannula may merely supply humidified air.

The nasal cannula was invented by Wilfred Jones and patented in 1949 by his employer, BOC.
