Abstract: A pressure regulating device includes a housing having a gases inlet adapted to in use be in fluid communication or integrated with a breathing assistance apparatus which conveys gases to an infant or a neonate requiring breathing assistance, an outlet adapted to be in use in fluid communication with said infant, and an aperture which enables the venting of a portion of gases that in use are passing through the housing from the inlet to the outlet. A tube inlet on the housing is adapted to receive a surfactant delivery device therethrough to enable administration of surfactant to the infant or neonate. A sealing mechanism seals around the surfactant delivery device and is adapted to normally fluidically seal the tube inlet and in use allow the surfactant delivery device to pass through the tube inlet.

Abstract: A pressure regulating device includes a housing having an inlet, a main outlet, an J an external venting outlet. An internal venting aperture is between the inlet and the external venting outlet. A valve is between the external venting outlet and the internal venting aperture. When the pressure of gases in the flow path is below a predetermined level, the valve at least partially blocks the internal venting aperture. When the pressure is above the predetermined level, the valve opens to allow at least a portion of the gases to flow from the inlet through the internal venting aperture and the external venting outlet. The valve is shaped to open in such a manner that the portion of gases flowing varies with the flow rate, such that the pressure at the main outlet is substantially constant over the flow rate range.

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 connector for resuscitating an infant or neonate is disclosed. The pressure is varied between Peak Inspiratory Pressure (PIP) and Peak End Expiratory Pressure (PEEP) by the occlusion of the PEEP outlet. The PEEP outlet may either allow variable PEEP, by adjustment, or substantially flow independent fixed PEEP using a novel umbrella valve. A duck billed valve is included for suctioning of surfactant delivery during resuscitation. The connector is adapted to one handed use.

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: The present invention relates to a Hydrogel cover for a temperature sensor. The sensor can be used on infants in a radiant warmer and/or incubator. In a first embodiment the sensor is fully enclosed by the Hydrogel. In a second embodiment the sensor may be removed through a releasable cover. This results in improved thermal response and/or accuracy.

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.
