摘要

Abstract

Objective

To explore a reliable and effective loading method for cleaning ventilator lines with an automatic spray washer so as to improve the pass rate of ventilator lines.

Methods

Ventilator lines of different lengths were randomly selected

180 each for the control group and the experimental group. In the control group

no specific requirements were made on the front and rear position of the pressure jet port inserting into the ventilator lines

the hang length of the pipeline end and the fixation. In the experimental group

the front and rear positions of the pressure jet port were selected according to the length of the ventilator lines

with the 30 cm long pipeline inserted in the rear row

the 60 cm long pipeline in the middle row and the 120 cm long pipeline in the front row. Choose the same pipeline cleaning procedure for cleaning and disinfection. The cleaning effect is evaluated in two approaches: method of visual inspection with illuminated magnifier and STF cleaning test card.

Results

The pass rate of the visual inspection was 99.4% in the control group and 100% in the experimental group. The pass rate of the two groups was

0.05

representing no statistical significance. The pass rate of the STF cleaning test card was 88.9% in the control group and 98.3% in the experimental group. The pass rate of the two groups was X2＝13.423

0.05

which was statistically significant. The pass rate of ventilator lines in the experimental group was significantly better than that in the control group.

Conclusion

The washing and disinfecting machine is effective to clean ventilator lines

a reliable and effective loading method helps to improve the pass rate and easy to operate

so that the quality of line cleaning is ensured and the nosocomial infection is prevented.
