PROBLEM TO BE SOLVED: To provide discomfort reduction means of a CPAP mask, because for curing a sleep apnea syndrome, a CPAP device is used, but when a user wears a CPAP mask 103, a user feels discomfort such as uneasiness and a user cannot sleep, and sometimes use of the CPAP device has to be stopped, therefore discomfort which is a factor has to be eliminated, and a CPAP device has to be useful.SOLUTION: A buffer member formed of a fiber body and an elastic body is formed between a CPAP mask 103 and a skin face 105 of a face, and an irregular pattern shape is formed on a face contact face side 2 of the CPAP mask 103, for solving the above-mentioned problem, thereby moisture of a contact portion 106 is absorbed, evaporated, and radiated, the irregular pattern shape serves as discomfort reduction means of the CPAP mask 103.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】 睡眠時無呼吸症候群の治癒の為、CPAP装置が使われる。しかしCPAPマスク103を装着時むず痒いような違和感があり、睡眠に入れない場合があり、CPAP装置の使用を断念せざるを得ない場合がある。要因である違和感を無くしCPAP装置を有用化することが課題である。【解決手段】 上記課題を解決する為、CPAPマスク103と顔の肌面105の間に繊維体と弾性体から成る緩衝部材を構成し及びCPAPマスク103の顔接触面側2に凹凸の模様形状を構成する事によって接触部位106の水分を吸収、蒸発、発散させCPAPマスク103の違和感軽減手段とした。【選択図】図1
