  • Patent number: 8434493
    Abstract: The adjustable mouth shield device provides an adjustably fitted mouth shield with adjustable headband for secure fit. The adjustable headband is fastened to the padded earpiece. The straight first extension from the earpiece is angled downwardly and forwardly to terminate in a swivel joint providing almost 360 degrees of swivel. The second extension is arced both downwardly and forwardly. The u-shaped mouthpiece is fitted to the adjustable spring mount for horizontal pivot of the mouthpiece. The mouthpiece may, by virtue of the swivel joint and the spring mount, be moved completely away from a user's mouth and, in turn, pivoted and swiveled to be directly in front of the user's mouth. The inward curves at the distal end of the mouthpiece aid in sliding on the disposable pads that shield a user from objects, foods and other materials.

  • Patent number: 7870860
    Abstract: A respiratory mask provides improved sealing through the use of an intraoral mouthpiece with a large sealing area. A tubular extension, configured at one end to accept standard respiratory fittings, is the conduit for gas delivery to the intraoral mouthpiece. The respiratory mask may also include an intraoral oropharyngeal airway which flexes so that it can be inserted without the need for rotation or use of a tongue blade. The respiratory mask may also include an external shield to enhance sealing and provide a barrier of protection for the healthcare provider. The mask's design allows for a novel handgrip technique that allows a single healthcare provider to ventilate with enhanced sealing.

  • Patent number: 7686014
    Abstract: The aim of the invention is to connect a nebulizer to a breathing air tube of a respirator. This aim is achieved by a nebulizer-connecting device that has a breathing air-directing unit that is provided with a first mechanism for connecting a duct supplying breathing air, a second mechanism for connecting a duct evacuating breathing air, and a third mechanism for connecting the nebulizer, and a sealing unit which is arranged on the third connecting mechanism and by which a flow path for an aerosol generated by the nebulizer can be unblocked when the nebulizer is connected while the flow path for an aerosol generated by the nebulizer can be sealed therewith when the nebulizer is removed. A sealing member is opened when the nebulizer is connected while being closed when the nebulizer is removed.

  • Patent number: 7481221
    Abstract: A breathing mask for breathing support devices (10) to guide the breathing support gas to the patient. The mask includes a mask body including a material that is permeable to air at least in partial areas. A gas guiding structure is provided which can be connected to suction openings of the breathing support device (10). The gas guiding structure extends through the interior of the mask body. The gas guiding structure for the transport/delivery of gas is limited partially by air-permeable areas of the wall of the mask body, through which ambient air can be drawn in. The mask is characterized by high wear comfort and improved safety against accidental coverage of the suction areas.

  • Patent number: 6615828
    Abstract: A respirator that comprises a head piece (1) that is shaped to form a breathing zone (13) around at least the nose and mouth of the wearer, and an air flow passage (15, 34) for supplying a forced flow of air to the breathing zone. The air flow passage has a constricted portion (46) that includes a flow detecting orifice (52). The forced flow of air generates suction at the flow-detecting orifice. A pressure-responsive indicator device (30) is in fluid communication with the flow-detecting orifice through a tube (54) and is operable to alert the wearer if the suction generated by the air flow through the passage falls below a predetermined value.

  • Patent number: 6394091
    Abstract: A breathing apparatus includes a regulator which delivers air to a user wearing a mask. The regulator is connected to the mask through an adaptor. The adaptor includes an exhalation valve which enables the user's breath to pass out of the adaptor to atmosphere. The regulator includes a sensing diaphragm that is movable responsive to pressure in the mask. A main valve delivers air to the mask responsive to opening of a pilot valve. The pilot valve includes a pilot opening. A lever moves in response to the sensing diaphragm to open the pilot opening which causes flow through the main valve. Air from the main valve is also delivered to a positive pressure chamber. Pressure in the positive pressure chamber moves a positive pressure diaphragm which causes a positive pressure spring to biasingly engage the sensing diaphragm. The biasing of the sensing diaphragm causes the regulator to maintain a positive pressure in the mask.
