Respiratory mask arrangement as well as headband arrangement and respiratory gas evacuation device for a respiratory mask

A respiratory mask, comprising:

• a covering portion of a woven material, the covering portion covering substantially an entire front side of the mask,
• a respiratory gas conduit connected to the woven material of the covering portion for delivering respiratory gas to the respiratory mask,
• a receiving portion formed on a back side of the mask, the receiving portion for receiving a nasal region of a user,
• a seal portion for forming a seal with the nasal region of the user,
• a first headband connector disposed on a first lateral side of the covering portion and a second headband connector disposed on a second lateral side of the covering portion, and
• a headband arrangement connected to the first headband connector and the second headband connector for securing the respiratory mask to the user, wherein the covering portion is configured to be inflated under the influence of the respiratory gas when the mask is worn.

A respiratory mask for delivering breathable gas to a patient at a level that is above ambient pressure, the mask comprising:

• a mask body including a front portion and a rear portion opposite the front portion, the front portion and the rear portion cooperating to define a mask interior to communicate with a source of pressurized gas,
• the rear portion including a seal portion to cross over the patient's nasal bridge region and seal around the patient's nose or the patient's nose and mouth when the mask is worn, and a receiving opening surrounded by the seal portion to receive the patient's nose or the patient's nose and mouth within the mask interior when the mask is worn,
• the front portion including a gas outflow area to provide a diffuse outflow of gas from the mask interior to atmosphere,
• a pair of headgear connectors, one of said pair of connectors extending laterally away from each side of the mask body,
• a headband arrangement coupled to each said headgear connector to support the mask body on the patient's head when the mask is worn,
• the front portion comprising a flexible portion of material which is configured to be inflated under the influence of the pressurized gas when the mask is worn, the flexible portion extending across the mask body from one side of the mask body to the other,
• the flexible portion of material includes at least one stitched seam segment, the at least one stitched seam segment and a shape of the flexible portion of material being configured and arranged to provide a defined shape upon supply of the pressurized gas to the mask interior, and
• a connection stub coupled to the flexible portion of material and adapted to be coupled to a respiratory gas hose.

A respiratory mask for delivering breathable gas to a patient at a level that is above ambient pressure, the mask comprising:

• a mask body including a front portion and a rear portion opposite the front portion, the front portion and the rear portion cooperating to define a mask interior to communicate with a source of pressurized gas,
• the rear portion including a nasal bridge region and 1) a nose region or 2) a nose region and a mouth region, the rear portion including a receiving opening to receive the patient's nose or the patient's nose and mouth within the mask interior when the mask is worn,
• the front portion including a gas outflow area to provide a diffuse outflow of gas from the mask interior to atmosphere,
• a pair of headgear connectors, one of said pair of connectors extending laterally away from each side of the mask body,
• a headband arrangement coupled to each said headgear connector to support the mask body on the patient's head when the mask is worn,
• the front portion consisting essentially of a flexible portion of material which is configured to be inflated under the influence of the pressurized gas when the mask is worn, and
• a connection stub coupled to the flexible portion of material and adapted to be coupled to a respiratory gas hose.

A respiratory mask for delivering breathable gas to a patient at a level that is above ambient pressure, the mask comprising:

• a mask body including a front portion and a rear portion opposite the front portion, the front portion and the rear portion cooperating to define a mask interior to communicate with a source of pressurized gas,
• the rear portion including a nasal bridge region and a lip region, the rear portion including a receiving opening to receive the patient's nose or the patient's nose and mouth within the mask interior when the mask is worn,
• the front portion including a top portion opposite from the nasal bridge region and a bottom portion opposite from the lip region, and the front portion including a gas outflow area to provide a diffuse outflow of gas from the mask interior to atmosphere,
• a pair of headgear connectors, one of said pair of connectors extending laterally away from each side of the mask body,
• a headband arrangement coupled to each said headgear connector to support the mask body on the patient's head when the mask is worn,
• the front portion consisting essentially of a flexible portion of woven air-permeable material which is configured to be inflated under the influence of the pressurized gas when the mask is worn, the flexible portion of material extending on the front portion over substantially an entire area between the pair of headgear connectors and between the top portion and the bottom portion, and
• a connection stub coupled to the flexible portion of material and adapted to be coupled to a respiratory gas hose.
