  • Publication number: 20150265795
    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 comprises 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.

  • Publication number: 20150209540
    Abstract: The present invention relates to a patient interface and a patient interface system comprising a responsive material and a method for preventing the formation of red marks due to wearing a patient interface (10) that is pressing against the skin of a patient (14) for a longer time and/or for reducing air leakages of the patient interface (10) that may result from an unintended shift of the patient interface (10) on the patient's face. The responsive material is configured for alternating the pressure exerted by the cushion element (18, 26) on the patient (14), and/or the area on the patient where the pressure is exerted by the cushion element in response to a physical quantity acting on the responsive material. The formation of red marks and of air leakages can be reduced or even avoided by means of the responsive material.

  • Patent number: 8731633
    Abstract: A device (1) is described for positioning electrodes on a user's scalp. It comprises a housing (3), for example a headpiece of a headphones device, which can be put around a user's head. An elastic element (11) and a plurality of electrodes are positioned, so that once the housing (3) is put around the user's head, the elastic element (11) at least partly follows the curvature of the user's head. The stress in the elastic element (11) due to stretching thereof caused by putting the housing around the user's head causes the elastic element (11) to exert pressure on at least some of the plurality of electrodes towards the scalp. Hereby, effective contact of the plurality of electrodes to the scalp is facilitated.
