RESPIRATORY MASK WITH PATCH RETAINED BY MAGNETIC ACTION Russian patent published in 2018 - IPC A61M16/06 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical technique, namely to patient interface for transporting gas to and/or from the patient's airways. Interface contains the front interface element of the patient interface. Face contact element comprises a surface for contact with the face of the patient. Said surface comprises a sealing member for contacting the face of the patient, a connection side for connecting the face interface of the patient interface to the support portion. Face contact member includes a first magnetic coupling mechanism, connected to connection side for connecting the face contact member to the rigid, in comparison with the face contact element, the mask body. Magnetic surface of the first magnetic coupling mechanism is perpendicular to direction of connection or is at an angle to the indicated direction of connection. Interface includes the reference part of the patient interface. Support part of the interface contains a rigid body of the mask. Mask body comprises a gas delivery connection for receiving gas for delivery to the patient. Body contains a connection surface for connection to front face of the patient interface. Support part includes a second magnetic coupling mechanism coupled to a connection surface for attaching a rigid mask body to front face of the patient interface. Magnetic surface of the second magnetic coupling mechanism is perpendicular to the connection direction or is angled to the indicated connection direction. Front patient interface contact member and the patient interface support part are connected using the first magnetic coupling mechanism and the second magnetic coupling mechanism.

EFFECT: technical result is to facilitate installation of replacement parts and to ensure reliable transportation of the gas inside and/or out of the patient's airways.
