  • Publication number: 20230158344
    Abstract: A breathing mask comprising a mask body, a mask bead, a strap holder and a filter device. Mask bead, strap holder and filter device are connected to the mask body and/or are part of the mask body. The breathing mask encloses the nose and mouth of the user, the mask bead partially delimiting a receiving opening for the nose and mouth. The filter device comprises at least one filter receptacle and at least one filter element. The mask bead has a bearing region configured as a sealing lip and is designed such that the breathing mask bears with the sealing lip on the facial skin around nose and mouth and provides a substantially leak-tight seal to respiratory gas. The filter device is at least in part exchangeable and respiratory gas can at least partially flow through it.

  • Publication number: 20230065584
    Abstract: The invention relates to a respiratory mask of modular construction. The main components are reduced to four parts and are provided by the mask body, the forehead support, the mask bead and the attachment piece. The design, according to the invention, of the outflow structure between mask body and forehead support makes apertures in the mask body unnecessary for this purpose. The strap coupling in the region of the mask body is made easier by a funnel-shaped guide structure such that it is possible in a simple manner even without seeing it.

  • Patent number: 9555207
    Abstract: The invention concerns a gel covering of a patient interface. This gel covering has a mask connection area by which its side that faces away from the patient is joined with a mask body. The patient interface can be designed, for example, as a respiratory mask. On its side that faces the patient's face, the respiratory mask has thin, inwardly formed, peripheral contact lips. The respiratory mask has accessories that allow it to be fastened on the patient's head as well as a hose connection for supplying air. At least one region formed from a filler is placed in or on the walls of the gel covering. The method is used to produce the gel covering of the invention.
