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.
