Abstract
Objective To design a set of ozone disinfection device for medical suspended bed to reduce the pollution of suspended bed particles and eliminate odor. Methods MCS-51 Single chip microcomputer was used to control the ozone generator. The ozone generator with an universal 10 g/h specifications was selected, and hardware was acted in series air source pipeline and software independent control of the flexible mode, which could be compatible with different brands of model suspension bed. In this case, the single chip microcomputer internal oscillator modules could be combined with the clinical needs of regular disinfection. Sampling before and after use of the device, the use of different culture media were quantitative and bacterial identification. Ultraviolet disinfection, cleaning disinfection and ozone disinfection were carried out respectively, and the efficiency of disinfection was compared. Results Before the ozone disinfection, the bed body particles were polluted seriously, the number of bacteria reached 3.977×106 cfu/g, the detection rate of pathogenic bacteria was 70％. After ozone disinfection, the amount of suspended particles in the suspended bed was reduced by 43.67％, and the number of pathogenic bacteria was decreased by 55％. Compared with ultraviolet disinfection and cleaning disinfection, ozone disinfection efficiency was higher. Conclusion Ozone disinfection device cost is low, can effectively remove the particles of suspended particles to kill bacteria, eliminate odor and improve clinical use effect.关键词
