What is BS EN ISO 10993-25:2017?

BS EN ISO 10993-25:2017 is a standard that addresses the biological evaluation of medical devices. It provides guidelines for assessing the potential risks associated with the use of medical devices in terms of their interaction with blood. This standard focuses specifically on the determination of the hemocompatibility of medical devices, which refers to their compatibility with blood and the components within it.

Importance of Hemocompatibility Testing

Hemocompatibility testing plays a crucial role in the development and evaluation of medical devices. The interaction between medical devices and blood can lead to various complications, such as thrombosis or inflammation. Therefore, it is essential to ensure that medical devices are safe and do not have any adverse effects on blood. Hemocompatibility testing helps identify and mitigate potential risks early in the design phase, ensuring patient safety and device effectiveness.

Key Parameters Evaluated

BS EN ISO 10993-25:2017 defines several key parameters that need to be evaluated during hemocompatibility testing. These include the assessment of red blood cell damage, coagulation activation, platelet activation, complement activation, and hemolysis. Each of these parameters provides valuable insights into the biocompatibility of the medical device and its potential impact on blood. By thoroughly evaluating these parameters, manufacturers can make informed decisions regarding the design and materials used in their medical devices.

Hemocompatibility Testing Methods

There are different methods available for conducting hemocompatibility testing. These may include direct contact methods, indirect contact methods, or a combination of both. Direct contact methods involve exposing the medical device material directly to blood, while indirect contact methods assess the response of blood components to extracts or eluates of the device material. Both methods have their advantages and limitations, and the choice of method depends on the specific requirements of the device under evaluation.
