A connector for resuscitating an infant or neonate is disclosed. The pressure is varied between Peak Inspiratory Pressure (PIP) and Peak End Expiratory Pressure (PEEP) by the occlusion of the PEEP outlet. The PEEP outlet may either allow variable PEEP, by adjustment, or substantially flow independent fixed PEEP using a novel umbrella valve (308). A duck billed valve (305) is included for suctioning of surfactant delivery during resuscitation. The connector (134) is adapted to one handed use.

An adjustable forehead support for a nasal mask. The present invention discloses an adjustable forehead support for a nasal or full-face mask wherein the forehead support may be adjusted for the different shapes and sizes of a facial profile. The forehead support utilizes a dual-arm system which adjusts the position of the forehead support vis-a-vis the mask and/or air flow tube. The angle of the mask to the face may be adjusted with the present invention.

Forehead support for facial mask

A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a main body and a side frame member provided on each lateral side of the main body. Each side frame member includes an integrally formed first connector portion. A headgear assembly is removably attachable to the frame. The headgear assembly has a second connector portion adapted to be removably coupled with the first connector portion provided on the frame. The second connector portion is manually movable to a releasing position to detach the headgear assembly from the frame. The headgear assembly is rotationally adjustable with respect to the frame.

Ergonomic and adjustable respiratory mask assembly with headgear assembly

A respiratory mask includes a frame including a breathable gas port, wherein the frame defines an inner chamber to receive at least one of a wearer's nasal region and mouth. The mask includes a cushion including a flange connected to the frame, an inner rim defining an opening to the inner chamber of the frame, and a sealing portion disposed between the flange and the inner rim to contact the wearer's face. The sealing portion includes a nasal seal section to span a wearer's face above the wearer's nares, side seal sections extending from each side of the nasal seal section on both sides of the wearer's mouth, and a chin seal section that extends between the side seal sections. The chin seal section is upwardly curved in an arch to follow the chin's bony contour.

Cushion for a respiratory mask assembly

A cushion for a patient interface that delivers breathable gas to a patient includes a base wall structured to be connected to a frame, an underlying support cushion extending away from the base wall towards the patient's face in use, and a membrane provided to substantially cover at least a portion of the underlying cushion. The membrane is adapted to form a continuous seal on the patient's face. The underlying cushion has a spring-like connection with the base wall. The underlying cushion and/or base wall define a spring constant that varies along a length of the seal.

Cushion for patient interface

PROBLEM TO BE SOLVED: To restrain dislocation of a mask by a body movement, and reduce gas leakage to the minimum extent by providing a bellows-shaped elastic body between a surface where the mask is brought into close contact with a face and a frame in which the mask is installed. SOLUTION: When a bellows-shaped elastic body 7 is placed between a frame 3 and a mask 1, a peripheral shape of bellows coincides with a peripheral shape of the mask to be connected, and the contour of a recessed line or a pointed line of the bellows exists on a plane. Silicone rubber or the like being a material of the mask is used as a material of the bellows-shaped elastic body, and when it is integrally molded with the mask, a manufacturing cost is reduced, and the easily installing merits are produced. The pitch number, a distance between pitches and a thickness of the bellows are decided by the magnitude of pressure of positive pressure gas to be used, the size of the mask, a dislocation quantity and a dislocation angle to be restrained and a material to be used or the like. A height of the bellows shaped elastic body 7 is set to 10 to 30 mm, and the pitch number is desirable to be 2 to 10 pieces. A thickness of the bellows is also desirable to be 1 to 3 mm.

Respiratory nose mask

PROBLEM TO BE SOLVED: To provide a nose mask capable of minimizing gas leakage from the boundary of the nose mask and a face without giving pains or uncomfortable feelings to a user and keeping the stability even against any movement of the user during sleeping SOLUTION: This mask is provided with a thin film for covering the periphery of the nose the user and an elastic body for holding the mask on the opposite side of the user surface of the thin film In this case, the lower shape of the elastic body for holding the mask corresponding to the lower part of the nose of the user is a circular-arcuate recessed shape whose curvature radius is longer than 30 mm and shorter than 40 mm and the length of a straight line for connecting both terminating points of the circular arc is longer than 50 mm and shorter than 60 mm
