DIN EN ISO 10993-4-2009 医疗设备的生物评估.第4部分:与血液相互作用试验选择(ISO 10993-4:2002,含修改件1:2006),DIN EN ISO 10993-4:2009-10的英文版本
Biological evaluation of medical devices - Part 4: Selection of tests for interactions with blood (ISO 10993-4:2002, including Amd 1:2006); English version of DIN EN ISO 10993-4:2009-10
This part of ISO 10993 provides general requirements for evaluating the interactions of medical devices with blood.
It describes
a) a classification of medical and dental devices that are intended for use in contact with blood, based on the
intended use and duration of contact as defined in ISO 10993-1,
b) the fundamental principles governing the evaluation of the interaction of devices with blood,
c) the rationale for structured selection of tests according to specific categories, together with the principles and
scientific basis of these tests.
Detailed requirements for testing cannot be specified because of limitations in the knowledge and precision of tests
for interactions of devices with blood. This part of ISO 10993 describes biological evaluation in general terms and
may not necessarily provide sufficient guidance for test methods for a specific device.
