Clinical application of novel oxygen humidification bottle drying rack / 医疗卫生装备

ABSTRACT

Objective To explore the practicability and feasibility of the oxygen humidification bottle drying rack for drying wet bottle and inner core.Methods Totally 600 sets of recovered humidification bottles and inner cores were cleaned and sterilized,and then divided equally into an experimental group and a control group.The experimental group used the oxygen humidification bottle and the control group applied the basket.The bottles and inner cores in the experimental group were placed upside down on the drying rack,and then underwent 3-h drying in the electric thermostatic drying cabinet (45 ℃).The bottles in the control group were placed in the plastic basket closely,and the inner cores were inserted in the gap between the bottles,then the bottles and inner cores went through 3-h drying in the electric thermostatic drying cabinet (45 ℃) as well.The two groups had 30 sets of bottles and inner cores dried at each time.Results The experimental had the drying rate (96％) significantly higher than that (68％) in the control group (x2=79.675,P＜0.005),while the rollover rate (0％) statistically lower than that (17.67％) in the control group (x2=58.14,P＜0.005).It's indicated that the experimental group behaved obviously better than the control group in drying rate and rollover rate.Conclusion The oxygen humiliation bottle drying rack has a good effect on fixing and drying wet bottles.The device can ensure the quality of disinfection,shorten the drying time and improve the working efficiency.
