Respiratory mask

Cushion for a nasal mask

Nasal mask

A headband assembly and a respiratory-mask system, wherein the headband assembly is of a planar structure in a spread and deployed state, and the headband assembly includes a head-mounting part () that is for clinging to and being worn on a head and connecting parts () that are connected to two sides of the head-mounting part () and are for connecting a respiratory mask; and the head-mounting part () includes an upper headband () that is for clinging to a top of the head and has a preset width and a rear headband () that is for clinging to a rear side of the head and is located under the upper headband (), wherein the upper headband () is of an arch structure whose concave faces the rear headband (). The headband assembly can cling to the head, to enable it to be firmly worn on the head.

Frame for respiratory mask

Cushion for respiratory mask

A cushion includes an accommodating cavity for accommodating a nose or oronasal part, which is defined by a contact portion, a connecting portion and an intermediate portion. The contact portion is configured to be in sealing contact with a patient's face. The connecting portion is configured to connect with a frame of the respiratory mask. The intermediate portion is connected between the contact portion and the connecting portion. The intermediate portion is formed with a recess portion recessed toward the accommodating cavity. The recess portion is formed into an arc or ring shape extending in a circumferential direction of the cushion, which includes a first connecting wall and a second connecting wall. A projection area Sof the first connecting wall on a vertical plane is smaller than a projection area Sof the second connecting wall.

A tube assembly includes a first tube piece and a second tube piece. The first tube piece includes an inlet end connecting a gas source and an outlet end connecting the second tube piece. The first tube piece includes a discharging hole that is configured so that, in a connecting state, the discharging hole is closed to make the gas to enter the second tube piece, in the separating state, the discharging hole is opened to make the gas to be discharged outside from the discharging hole. The tube assembly includes a valve member that is configured so that, in the connecting state, the valve member opens the outlet end of the first tube piece to make the gas to enter the second tube piece, and in the separating state, the valve member closes the outlet end to make the gas to be discharged outside from the discharging hole.

Ventilation treatment device and ventilation-control method

A ventilation treatment device and a ventilation-control method are provided. During use, when a headband contacts a headrest, a first valve assembly contacts a second valve assembly to open first air holes and second air holes, thereby communicating a first chamber with a second chamber, such that air from an air source into the first chamber enters the second chamber and further enters a respiratory chamber of a patient connecting apparatus for inhalation by a patient; and when the headband is separated from the headrest, the first valve assembly and the second value assembly are separated to close the first air holes and the second air holes, thereby preventing the air in the first chamber and the second chamber from flowing out through the first air holes and the second air holes, respectively.

A respiratory mask connector and a respiratory mask. The respiratory mask connector is configured to connect a frame to a connection pipe. The respiratory mask connector has a connection face and a spherical face, the connection face being configured to be connected to the frame, and the spherical face being configured to be in ball-socket connection with a pipe head of the connection pipe. The connection face and the spherical face are respectively configured as either the outer wall surface of the respiratory mask connector or the inner wall surface of the respiratory mask connector. The respiratory mask connector can be used for a respiratory mask.

Respiratory mask connector and respiratory mask

A cushion for a breathing mask and a breathing mask. The cushion includes a connection portion for connecting to a frame or an elbow assembly of the breathing mask; a face contact portion for getting in contact with the face of a patient, wherein the face contact portion is formed by a thin membrane; and a support portion which is connected between the connection portion and the face contact portion, wherein the face contact portion has an outwardly extending portion which extends from the support portion to the exterior of the cushion and an inwardly extending portion which extends from the outer circumference side of the outwardly extending portion to the interior of the cushion in at least partial area.
