摘要:
A mask system has a shroud module with headgear connectors adapted to removably attach to respective headgear straps of headgear; and a cushion module, including a frame defining a breathing chamber; and a cushion to form a seal with the patient's face in a nasal bridge region, a cheek region and a lower lip/chin region of the patient's face. The cushion is constructed of a first, relatively soft, elastomeric material and the frame is constructed of a second material that is more rigid than the cushion, and a nasal bridge portion of the cushion includes one or more folds to provide in use a higher level of adaptability or flexibility to the nasal bridge region of the cushion module relative to another region of the cushion module. The shroud module and the cushion module are configured to be removably coupleable to one another.

According to the present device, system, and method, the respiratory assistance mask comprising a hollow body bounding an internal chamber provided with a respiratory gas inlet and outlet, and a bearing member is remarkable in that it also comprises: a flexible membrane inserted on said bearing member and being able to be interposed between said bearing member and the face of said patient; and a multi-perforated internal skirt inserted, thru one of its two contours, on said bearing member and surrounded, at least partially, by said flexible membrane, the free contour of said skirt extending in direction of said internal chamber.
摘要:
A cushion arrangement for a patient interface (for communicating with the nose or the nose and mouth of a patient) comprises a cushion and a shaping structure in contact with the cushion. The shaping the comprises a thermo-shrink material, and the local dimension of themo-shrink material determines a level of local compression or expansion of the cushion. The shaping structure enables the cushion to be customised for the end user.
摘要:
The present inention provides a cost effective customization of user interface devices for use with respiratory ventilation systems, such as face masks that may be used for CPAP therapy. By integrating a user specific customize element (15) into a pre-fabricated user interface device (10), increased confort for a user during use of the interface device (10) is provided. The customized element (15) is adapted to affect the shape of the user interface device making it compliant with at least one user specific body feature, for example, a facial feature of a particular user. The shape of the customized element may be computed from a user specific data set representing an e.g. three-dimensional shape at least one body feature of a user.
摘要:
A respiratory assistance component is disclosed that changes shape when an electrical charge is provided. The amount of electrical charge that is applied may be based on values, characteristics, or user controlled parameters of the respiratory assistance system. The component may be all or part of a patient interface, a tube, a flow generator, and/or a sleep mat.
摘要:
A respiratory mask assembly for delivering breathable gas to a patient includes a frame and a headgear assembly which are adapted to being remove ably magnetically coupled to one another at a desired angular orientation therebetween.
摘要:
A connector (36) is employed in a patient interface (2) that provides a flow of breathable gas to an airway of a patient. The connector includes a support apparatus (48) and a connection apparatus (50). The support apparatus is connected with a source of a breathable gas (4). The connection apparatus is disposed on the support apparatus and is engaged with the cushion. The connection apparatus includes an engagement element (78) and a retention apparatus (80). The engagement element has a frusto-conic engagement surface (84) that is structured to receive against it at least a portion of the cushion. The retention apparatus includes at least a first retention element (86) engaged with the cushion and retaining the at least portion of the cushion in a condition received against the engagement surface.
摘要:
A connector arrangement joining a respiratory mask and headgear is adapted for single-handed disengagement by the patient. A first, rigid connector part is formed into the rigid mask frame, with a mating second connector attached to a strap of the headgear. The connectors are held away from the patient's face by the connection to the mask frame.
摘要:
A CPAP or other ventilation system includes a mask, a flow generator, a positive or high pressure line to provide positive or high pressure air from the flow generator to the mask and a vacuum or return line provided to actively extract exhaled gas from the breathing chamber and/or the air delivery conduit of the mask. The vacuum or return line includes a vent outlet preferably positioned remote from the mask.
摘要:
A cushion (16) for use with a mask (10) in delivering a flow of breathing gas to a user includes a first portion adapted to contact a surface of a user, a second portion adapted to be coupled to a mask shell (18), and a wall portion extending between the first portion and the second portion. The wall portion includes a chamber formed therein, the chamber having one of an electro-rheological fluid or a magneto-rheological fluid disposed therein. The cushion further includes a means (44, 50) for selectively varying the apparent viscosity of the fluid disposed within the chamber.
