目的观察汽化过氧化氢消毒机对医院妇科门诊手术室消毒效果。方法采用模拟现场消毒试验方法,对某汽化过氧化氢消毒机消毒医院妇科门诊手术室内空气和环境物体表面的效果进行观察。结果该汽化过氧化氢消毒机以浓度为1 800 mg/m~3汽化喷雾作用60 min,对无人条件下的72 m~3妇科门诊密闭手术室和90 m~3走廊内布放的各点嗜热脂肪芽孢杆菌芽孢菌片上全部无菌生长;同样条件下,消毒作用后手术室环境物体表面上自然菌采样培养全部达到无菌生长。消毒后自然降解60 min,室内空气中过氧化氢残余量均<0.71 mg/m~3。结论采用汽化过氧化氢消毒机对医院妇科手术室内空气和物体表面可同时达到高级别消毒效果,消毒后无消毒剂残留。
Objective To observe the disinfection effect of vaporized hydrogen peroxide disinfection machine on the operating room of gynecological clinic in the hospital. Methods By simulating field disinfection test method, the effect of a vaporization hydrogen peroxide disinfection machine on the surface of indoor air and environmental objects in the hospital gynecological clinic was observed. Results The vaporization hydrogen peroxide was sprayed at a concentration of 1 800 mg / m ~ 3 for 60 min, and each of the 72 m ~ 3 gynecological outpatient closed operating rooms and 90 m ~ 3 corridors under unmanned conditions Bacillus stearothermophilus Bacillus spores on the whole aseptic growth; the same conditions, the disinfection of environmental objects in the operating room on the surface all the natural bacteria to achieve aseptic growth. Natural degradation after disinfection 60 min, indoor air residual hydrogen peroxide were <0.71 mg / m ~ 3. Conclusion The use of vaporization of hydrogen peroxide disinfection of hospital gynecological operations indoor air and surface of objects can achieve high-level disinfection effect, no disinfectant after disinfection.
