A medical ventilator case includes an outer housing, an inner housing installed inside the outer housing, and sound-absorbing cotton forming a flow channel in the inner housing. According to the above arrangement, an air blower for pumping air can be arranged in the inner housing of the medical ventilator case to form a medical ventilator. The inner housing is for receiving oxygen or air delivered from outside, and air inside the inner housing is inhaled by the air blower along the flow channel formed by the sound-absorbing cotton and then outputted to a required position. The medical ventilator case can effectively reduce noise of the medical ventilator with a sound-absorbing function provided by the sound-absorbing cotton and a shielding function provided by the inner housing and the outer housing. In addition, the inner housing can concentrate air for improving efficiency of air extraction of the air blower, so as to further reduce heat generated by the air blower.一種呼吸器機殼,係於一外殼體內設有一內殼體,並於內殼體設有一形成有一流道之吸音棉;藉此,機殼可用以於內殼體內設置一用以壓送氣體之鼓風機,以組成一呼吸器,內殼體係用以接收由外部輸入之氧氣或空氣,且內殼體內之氣體會沿吸音棉之流道被鼓風機吸入,再被輸出至所需之處;藉由吸音棉之吸音功能及內、外殼體之遮蔽功能,機殼可有效減低呼吸器之噪音,另外,內殼體可使氣體更為集中,以提高鼓風機抽取氣體之效率,進而減少鼓風機產生之熱能。10...呼吸器機殼20...殼件組21...下殼件212...底部214...外凸垣216...內凸垣28...內殼體30...第一吸音棉32...流道324...入口40...第二吸音棉50...鼓風機58...出氣口61...防震底板62...防震夾板63...防震立板70...第三吸音棉
