title: [Study on particle contamination produced by syringe needles and rubber stoppers for pharmaceutical solutions].
abstract: The contamination of particles produced by syringe needles and rubber stoppers for pharmacal solution of venous transfusion was studied. The results showed that the contamination of particles was positive correlation with the usage frequency of syringe needles, so the syringe needles for single use were suggested. To compare two kinds of syringe needles with different structure (side hole and incline), the result was that the difference of particle contamination between them was similar and without statistic significance. The particles contamination produced by primary and used rubber stoppers which was protected by polyester film was studied. It was shown that the difference between them was no significant statistically. The results of this study supplyed a scientific evidence about repeated use of rubber stoppers.
