气道雾化疗法是口腔疾病治疗的重要手段,治疗时雾化吸入装置直接与口腔粘膜接触,促其吸收药物,达到消炎的目的。其雾滴也可深达小支气管,经肺部吸收进入血液控制疾病。但污染的雾化装置会作为重要的传播途径引起医院内呼吸道感染而加重原基础疾病。为此,我们对口腔疾病患者所使用的GZ型射流雾化器(以下简称雾化器)的细菌污染情 Airway aerosol therapy is an important means of oral disease treatment, treatment of inhalation devices directly contact with the oral mucosa, and promote its absorption of drugs to achieve the purpose of anti-inflammatory. Its droplets can also be as deep as a small bronchus, absorbed by the lungs into the blood to control the disease. However, the contaminated atomization device can be used as an important transmission route to cause respiratory infections in hospitals and aggravate the original underlying diseases. To this end, we used in patients with oral diseases GZ jet nebulizer (hereinafter referred to as nebulizer) of bacterial contamination
