  • Patent number: 10532172
    Abstract: A patient interface device uses a pressure flap which extends inwardly from an outer edge of a mask of the device. The pressure flap is for contacting the skin of the patient to provide a seal or partial seal between the mask volume and the ambient surroundings. The pressure flap includes a cavity area which is exposed to a reduced pressure compared to the mask volume. This assists in keeping the pressure flap pressed against the patient's skin, and thereby maintain a large contact area. This in turn gives a reduction in local high pressure areas.

  • Patent number: 9282778
    Abstract: An infant hat with a pacifier retaining strap retains and secures a pacifier nearby an infant's mouth. The device includes a hat and a pair of fastening straps. The hat is a headgear member adapted for wear on a head of an infant. Each of the straps is a durable fabric member affixed to a perimeter side portion of the hat. Each strap has a fastener which allows the free end of strap to be secured to a middle portion of itself to form a loop. In such a manner, both straps loop through a pair of pacifier mouth guard slits while an infant is wearing the hat in order to provide secure retention of the pacifier within or adjacent to the infant's mouth. In an alternate embodiment, the pair of fastening straps attach to a separate retaining ring capable of engaging a rear of the pacifier guard.
