Embodiment Construction

[0020] The present invention provides a nasal pad and mask assembly for CPAP therapy of a patient. Those skilled in the art will appreciate that the embodiments of the present invention are exemplary and should not be construed as limiting the scope of the invention as defined by the appended claims. Advantageously, the components of the mask assembly provide a variety of adjustment ranges and positioning angles, enabling a highly customizable fit to accommodate variations in the patient's head size and facial features while efficiently delivering gas to the patient's nose .

[0021] Figure 1 is a side perspective view showing a mask assembly 2 in place on the head of a patient 1 for treatment. The mask assembly 2 includes a helmet 3, nasal pads 4 and a mask frame 11 which cooperate to position the nasal pads 4 around the nose of the patient 1 and maintain their position during treatment. The helmet 3 comprises a head strap 6 , a rotatable arm 7 , a neck strap 8 and a cheek ...

Abstract

The present invention provides a nasal pad for use in a mask assembly for delivering pressurized gas to a patient's nose for therapy under continuous positive air pressure. The nose pad includes self-supporting side walls defining a nose receiving cavity; the side walls extending from a first end to a second end. The side wall is continuously formed by a thin septum, wherein the septum extends inwardly from the second end of the side wall into the nose receiving cavity so as to seal with the patient's nose, upper lip and cheek join. The sidewall has a continuously varying thickness. The first end of the side wall is adapted to engage a mask frame. The present invention also provides a mask assembly for delivering pressurized air to a patient, the assembly including nasal pads for sealing over the nose, cheek and lip areas, the nasal pads being as described; for receiving the nasal pads a frame; and a helmet; the helmet includes rigid arms for positioning behind the patient's ears.

Description

technical field [0001] The present invention relates to masks for delivering gas to a patient, particularly CPAP and VPAP masks and mask assemblies. Background technique [0002] Many treatments of a patient require the use of a mask to supply gas, particularly air, to the patient's nose. For example, in the treatment of sleep apnea, particularly obstructive sleep apnea (OSA), air is typically delivered through a mask at either continuous positive pressure (CPAP) or variable positive pressure (VPAP) to the nose of a sleeping patient in order to Keeping the patient's airway open for efficient breathing, in which air is continuously supplied at a pressure greater than ambient pressure in continuous positive pressure conditions, or at variable pressures in variable positive pressure conditions. Typically, air must be delivered continuously through the mask for a certain period of time, for example, throughout the night of sleep. [0003] It is important for continuous therape...
