        Abstract：ObjectiveTo 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.MethodsVentilator 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.ResultsThe 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 P>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, P<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.ConclusionThe 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.

        Abstract：ObjectiveTo study the wet pack incidence of rigid containers applying different structures of silicone protective pads for packaging instruments.Methods72 surgical instruments were packed in rigid containers and divided into three groups according to the different structures of silicone pads. The rigid container boxes and the instruments loaded in the three groups were the same, and the silicone pads used in groups A and B were flat-bottomed on one side and papillary on the other side. All three groups adopted the same sterilization procedure with pressure steam, and the wet pack incidences was counted after the sterilization procedure.ResultsThe wet pack incidences in groups A and B was 59.5% and 29.8%, respectively, which was significantly higher than that in group C with 0%. The difference was statistically significant (P<0.05).ConclusionThe wet pack incidence in rigid container boxes with different silicone pads is related to the structure of the built-in silicone pads. In groups A and B, steam is not able to penetrate because of the small density of the silicone pad grid openings. The steam in the box is not smoothly discharged, and condensate accumulation is not easy to dry. In group C, silicone pad with more grids and large grid openings is conducive to sterilization steam penetration, resulting in smooth discharge of the steam in the rigid container box and less condensate accumulation. When the rigid container box applies different structures of silicone protection pads to protect the instruments for packaging instruments, the silicone pads with large grids and flat structures should be adopted to prevent the wet packs and ensure the quality of sterilization.

        Abstract：ObjectiveAdopt a modified double-layer microgroove basket to hold the oral root canal files for cleaning so as to improve the cleaning quality and to avoid sharp injury to the operator.MethodsThe cleaning quality was observed in the experimental group and the control group by randomly grouping 100 root canal files after recovery. 50 files in the experimental group were loaded and cleaned with modified double-layer microgroove baskets and 50 files in the control group were loaded and cleaned with stainless steel mesh cups.ResultsIn the experimental group, the cleaning pass rate of root canal files was 98% and the bending rate was 0. In the control group, the cleaning pass rate of root canal files was 86% and the bending rate was 18% (χ2=4.891, P<0.05; χ2=9.890, P<0.05). Before the modified double-layer microgroove baskets were adopted for cleaning before loading and cleaning the root canal files, 26 sharp injuries occurred in 25 medical workers in one year, with an average of 1.04±0.28. After the baskets were adopted, 8 sharp injuries occurred with with an average of 0.32±0.125. There was a significant difference in the average of sharp injuries before and after using the modified microgroove basket (Z=‒3.211, P<0.01).ConclusionThe modified double-layer microgroove basket for cleaning sharp instruments in the oral cavity can improve the cleaning pass rate of root canal files and effectively reduce the incidence of sharp injuries to medical personnel.
