Disclosed is a mask bead for a patient interface that comprises a contact area, a nose bridge area having a width (B), side areas, a base area, and a bearing area on a patient. The bearing area extends from the side areas, the base area and the nose bridge area to a central opening is being designed as a sealing lip which frames the central opening. The mask bead further has a maximum width (B), the ratio Bto Bbeing one to three or greater.

Mask bead for a patient interface

The invention relates to a respiratory mask having a mask unit and having an emission device for discharging exhaled gas from the respiratory mask. The mask unit comprises a mask body and a connection unit which can be connected to the mask body for connection of a respiratory gas feed line. The emission device comprises a plurality of flow channels, which are arranged in at least one part of the mask unit. Here the emission device comprises at least one flow channel.

Respiratory mask and process for making a respiratory mask

The present invention relates to a mask bead for a patient interface, comprising a nose bridge region, at least one side region, a base region, a mask bead attachment, and a bearing region on the patient. The bearing region extends from the side regions and the base region and also the nose bridge region to an opening and is designed as a sealing lip which frames the central opening which serves at least for the introduction of the nose of the patient. The mask bead is formed from at least one elastic material and comprises at least one support structure in the mask bead, which support structure is designed to in part face the bearing region and to in part face the mask bead attachment.

Mask bead

A forehead support for supporting a respiratory mask having a forehead support stem and a forehead rest. The forehead rest comprises a guide bar which can be guided over a resilient element that is formed in the forehead support stem. The forehead support stem may be forked.

Device for supporting a respiratory mask with integral functional elements

Disclosed is a respiratory device comprising a connecting socket which is inserted at least partially into a rotary sleeve and is latched thereto. The connecting socket and the rotary sleeve are disposed between a respiration hose and a patient interface, the connecting socket having an external diameter which is smaller than the internal diameter of the rotary sleeve. The rotary sleeve comprises on its inner side latching elements which engage in latching elements on the external diameter of the socket.

Connecting socket and rotary sleeve for respiration

The invention relates to a respiratory mask with an interface for the connection of at least two components, wherein the interface is round or oval and has a maximum diameter, and the components each make available at least one subregion of the interface. The component has a grip part which extends radially outward from the subregion and which is configured as a pressing surface or gripping means for fingers or the hand of an operator, wherein the component has two grip parts, wherein the subregions are in form-fit engagement with each other in an assembled state and are movable about a rotation axis (DA), for which purpose the grip part is rotatable to different rotation positions relative to the two grip parts.

Breathing mask interface with small required operating force

The invention relates to a respiratory mask () having a mask unit () and having an emission device () for discharging exhaled gas from the respiratory mask (). The mask unit () comprises a mask body () and a connection unit () which can be connected to the mask body () for connection of a respiratory gas feed line (). The emission device () comprises a plurality of flow channels (), which are arranged in at least one part of the mask unit (). Here the emission device () comprises at least one flow channel.

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.

Breathing mask with coupling elements for head strap

A medical/technical device comprised of at least two materials. The materials are connected at least partially to each other permanently by a manufacturing process.

Device consisting of at least two materials

Disclosed is a respiratory mask featuring a mask body and an articulated connection piece that can be connected to a respiratory tube. On the mask body, at least one exhalation gap is located in the vicinity of a connection that holds the articulated connection piece. Preferably, the exhalation gap terminates in an umbrella-shaped outflow channel that runs away from the patient. Preferably, at least two components of the respiratory mask are interconnected without play.
