为此，我们应该加大医疗器械安全性评价动物试验替代方法的科研投入力度，以尽快实现与国际先进方法接轨。
We should spend more scientific research to animal testing alternatives of medical devices safety evaluation in order to keep up with the international advanced technology.
简要介绍了生物材料和医疗器械安全性评价中动物试验替代方法的研究进展。
In this article, the authors briefly review the progress of alternatives to the animal testing in the safety evaluation of biomaterial and medical devices.
他们提出“3R原则”，即减少动物使用量（replacetestingonanimals）、改善试验方法以减轻动物痛苦（refine their experimentsto minimise distress）和用非活体动物实验替代动物实验（replace testing on animals with alternativetechniques）。
They wanted scientists to restrict the use of animals, to refine their experiments to minimise distress and to replace testing on animals with alternative techniques.
