Abstract: A nasal cannula for delivering respiratory gas to a neonatal infant includes a gas inlet configured to engage a respiratory conduit, a gas outlet configured to engage an expiratory conduit, and a pair of nasal prongs. The gases inlet and the gases outlet are in fluid communication via a low resistance path. Each of the nasal prongs is located substantially equidistant from, and in fluid communication with, the gases inlet, and substantially equidistant from and in fluid communication with, the gases outlet. The nasal prongs are juxtaposed directly in the low resistance path.

Abstract: A improved interface is disclosed for delivering CPAP therapy to patients. The interface has a sliding engagement to the headgear. The sliding engagement allows substantial relative lateral movement eg: when face is distorted from sleeping on side, while still providing adequate compressive force to avoid side leakage. The sliding engagement also allows easy release from the headgear.

Abstract: A nasal cannula (100) for delivering respiratory gases to a neonatal infant comprising a manifold including a chamber (10), a gases inlet (16) to the chamber and a gases outlet (12), a low resistance path for gases through the chamber from its inlet to its outlet and a pair of nasal prongs (116, 118) in fluid communication with the chamber with each prong substantial equidistant the inlet, and directly in the low resistance path to eliminate deadspace.

Abstract: A pressure regulating device for use with a breathing assistance apparatus which conveys gases to a patient requiring breathing assistance. The device includes a valve member disposed within a valve housing which when gases flowing through the regulator reach a predetermined level at least a portion of the gases are permitted to flow through a vent aperture externally, similar to known pressure relief valves. The present invention includes an adjustment mechanism engaged with the valve member and for adjusting the predetermined level, and a locking mechanism for permanently preventing access to the adjustment mechanism once the predetermined level has been factory set.
