  • Publication number: 20040079374
    Abstract: According to one embodiment of the invention, a method of forming a custom fitted mask includes transitioning a mask blank including a thin sheet of deformable material from a non-deformable state into a deformable state. The mask blank is applied against at least a portion of a user's face surrounding the user's nostrils while the mask blank is in the deformable state. The mask blank is deformed against the portion of the user's face to cause the mask blank to conform substantially optimally to the user's unique bone structure and facial features, the mask blank once conformed substantially optimally to the user's unique bone structure and facial features becoming the custom fitted mask. The custom fitted mask is allowed to transition from the deformable state into the non-deformable state for use.

  • Patent number: 6571798
    Abstract: A device (8) for improving a user's breathing includes an oral appliance (10) and a connecting post (20) coupled to the oral appliance (10). The connecting post (20) has an arm (22) providing a standard interface to engage cooperatively shaped openings (40, 42) in other components (24, 26, 44, 60) each designed to improve the user's breathing in at least one respect. A CPAP interface (44) coupled to the arm (22) may deliver a gas to the user's nose to improve the user's breathing. A venting seal (24) coupled to the arm (22) may reduce venting of the gas from the user's mouth to further improve the user's breathing. The CPAP interface (44) may include a pair of nasal pillows (30) that seat within a portion of the user's nose to deliver the gas to the user. A pair of tubes (48) are coupled to the nasal pillows (30).

  • Patent number: 6464924
    Abstract: A method of forming a custom mask (40) includes introducing a deformable material (32) to an impression mask (24) and directing the deformable material (32) against at least a portion of a user's face within the impression mask (24). This forms an impression of the user's face in the deformable material (32) to form the custom mask (40). The impression mask (24) receives the deformable material (32) and directs the deformable material (32) against at least a portion of a user's face within the impression mask (24) in response to pressure applied to the impression mask (24). The deformable material (32) may include a polycaprolactone polymer or an aliphatic polyester. The impression mask (24) may receive the deformable material (32) either before the user's face is brought within the impression mask (24) or while the user's face is within the impression mask (24).
