The present invention is a high-pressure oxygen chamber, particularly for pet medical care and care. The high-pressure oxygen chamber includes an oxygen supply device, an air dehumidification device and a cabin; and the gas pipeline connection and operation between the devices can be The chamber is filled with oxygen and pressurized to maintain a predetermined absolute atmospheric pressure value, thereby providing a pet entering the cabin to receive high-pressure oxygen stimulation, thereby increasing blood oxygen concentration, improving pet body tissue hypoxia and promoting The wound heals and enhances the bactericidal ability of white blood cells for the purpose of treatment and care.本創作係一種高壓氧氣艙,特別係用於寵物醫療及照護,該高壓氧氣艙包括一氧氣供給裝置、一空氣除溼裝置與一艙體;藉由上述裝置間的氣體管道連接與運作,可使該艙體灌入氧氣並加壓維持在一預設定的絕對大氣壓力值,藉以提供進入艙體的寵物可接受高壓氧氣刺激,進而提高血中含氧濃度,改善寵物身體組織缺氧及促進傷口癒合,並增強白血球之殺菌能力,以達到治療、照護之目的。
