In this study,gamma radiation and steam sterilization(Autoclaving) were employed to nano-hydroxyapatite(n-HA) reinforced polyamide 66(PA66) composites.

This paper primarily introduces the basic characters, hazards of salmonella, and the mechanism, parameters of feed conditioning for steam sterilization as well as the novel feed conditioners.

Methods 30 complete sets of reusable ventilator pipelines and humidifiers in the control group were sterilized with 5% chlorine disinfectant,another 30 sets with fully automatic washer disinfector at economic program as the first observation group and the last 30 sets as the second observation group with fully automatic washer disinfector plus steam sterilization.

Study on the Testing about the Pressure Vessel of Steam Sterilizer

Objective To explore problems of chemical indicative cards and adhesive tapes in the disinfection,and find out some measures for improving the sterilizing effect of the pressure steam sterilizer.

RESULTS Pressure steam sterilization was unable to achieve 100% sterilizing effect,whether we extended the time or use the intermittent(sterilization).

Objective To study the period of validity of autoclave sterilization to textile packaged medical devices under different conditions of temperatures and humidity so as to decrease devices damage,lengthen their lifespan and save the manpower and the resources.
