Objective

2

To analyze the drying effect of two groups of simple respirator drying methods and explore a better drying method.

Methods

2

120 simple respirators cleaned and disinfected in the disinfection supply room of a 3A hospital in January 2021 were selected and randomly divided into control group (60 drying cabinets) and observation group (60 drying racks+drying cabinets). The remaining water stains in the respirators were absorbed and weighed with 0.3 g cotton balls after 10 and 15 minutes of drying respectively. The results of 10 and 15 minutes of drying were compared between the two groups 15 minutes of drying and the number of cases of complete drying

two groups of drying methods

all respirators complete drying time.

Results

2

After drying for 10 minutes

the weight gain of the control group was 2.45%±20 g

the weight gain of cotton ball in the observation group was 0.62±19 g

0 in the control group and 7 in the observation group

P=0.004; After drying for 15 minutes

the weight gain of cotton balls in the control group was 2.14%±52 g

the weight gain of cotton ball in the observation group was 0.29±0.04 g

the number of completely dry cases in the control group was 0

and the number of dry cases in the observation group was 19

P

=0.00. The complete drying time of the control group was 95.72±07 minutes; The complete drying time of the observation group was 13.10±75 minutes

P=0.00

the difference was statistically significant (

P

<

0.05).

Conclusion

2

Using self-made drying frame can shorten the drying time of simple respirator

improve the qualified rate of respirator drying and the working efficiency of disinfection supply center.
