For reducing a discomfort feeling brought by wearing a breathing mask, a wearing tool for the breathing mask which covers nostrils of a user and supplies gas for breathing to the nostrils comprises a pair of connecting members each of which has a longitudinal shape and has a first end portion which is connected to the breathing mask, and a pair of fixing members each of which is connected to a second end portion of the fixing member and is plugged in the tragus of the user. Hence a discomfort feeling due to restraining around the head of the user can be reduced.

Wearing tool for breathing mask, and breathing mask

The present invention relates to a nasal respiratory mask system comprising: a nasal mask that is tightly attached to the face of a user and serves as means for leading positive-pressure breathing gas to the nose of the user, a frame to keep the nasal mask at a predetermined position, and a headgear that is mounted on the head in order to attach the nasal mask tightly to the face; wherein, the headgear comprises, on the tip thereof, a headgear strap for adjusting the length of the headgear, the headgear strap comprises a headgear fastener that serves as means for connection/disconnection with the frame, the frame comprises a fastener catch that engages with the headgear fastener, and the fastener catch comprises an axisymmetric guide whose (rotation) axis is the insertion direction of the headgear fastener. The present invention provides a nasal respiratory mask system with which a headgear can be easily connected at the beginning of wearing, twisting of the headgear during wearing is prevented, and disassembly upon daily washing is easy.

Nasal respiratory mask system and connection/disconnection means used therein

A light weight nasal respiratory mask system securing airtightness of a mounting section between a nasal mask and a frame is provided. A nasal respiratory mask system contacting the face of a user to supply respiratory gas under positive pressure to the nose of a use and comprising at least a nasal mask, a frame and a retention wire, in which the nasal mask is a tubular member composed of a face contacting section constructed from an elastic body at one end of an opening and a frame mounting section constructed from an elastic body at the other end of the opening, the frame is a molded part with an internal space capable of communicating between a hose to supply positive pressure gas and the nasal mask and has a mechanism connectable with the hose to supply positive pressure gas and a nasal mask mounting section allowing the nasal mask to mount on periphery thereof, the frame mounting section of the nasal mask is mounted to cover from the outside the nasal mask mounting section of the frame, and at least part of the retention wire has a structure to tighten the frame mounting section of the nasal mask to the side of nasal mask mounting section of the frame.

Nasal respiratory mask system

A headgear suitable for wearing a respiratory mask system wearing on the head of a user is provided, wherein it can be easily manufactured, the leakage of the positive pressure gas when pressurized is reduced, and a good wearing feel is achieved. The headgear is adapted to secure a respiratory mask, which contacts the face of the user to supply a positive pressure gas for respiration to the user, to the head of user. The headgear has a head mounted portion which is worn on the occipital of the user and a strap () connecting to this head mounted portion. The head mounted portion has at least one closed curved belt () which has thereon at least one junction (). At least one junction provides the closed curved belt with a nonplanar structure adaptable to the shape of the head of the user.
