The Oracle HC452 Oral CPAP Mask is a unique mask which delivers CPAP therapy through the mouth only. It features diffused exhalation, an adjustment dial, and single strap headgear.
Fisher & Paykel Healthcare is the first company to develop an oral mask. The Oracle HC452 delivers air pressure only through a mouthpiece. The mask has been clinically proven to treat OSA and offers a viable alternative to a full face mask, with less structure against the face. This is the second generation of Oracle and builds on the original design.
Here is how it works:
The mouthpiece comes in two sizes and is placed behind the lips and in front of the teeth. An outside flap is then fitted into the mouthpiece and folded over the lips. This combination keeps the device stable in the mouth and has been redesigned without the inner flap of the earlier design, which rested on the tongue.
The features of the Oracle mask include:
- Bias Diffuser. The Oracle mask has an exhalation vent design of a series of small holes and uses a filter to help reduce noise. The mask comes with five filters.
- Rotating Adjustment Dial. This dial adjusts the space between the SnapFlap Cover and SoftSeal mouthpiece to increase comfort and stability and can be used after the mask has been fitted into the mouth. This is an upgrade to the earlier design of the Oracle.
- Single Strap Easy-Release Headgear. One strap around the back of the head keeps the Oracle stable and a swivel in the front of the mask allows free rotation of the CPAP hose. The headgear is adjusted once, then easily removed with just a pull of the Easy-Release cord. No ongoing adjustments are needed. The headgear of the Oracle is latex free, as are all other headgear by Fisher & Paykel.
