Why should you use this standard?

These responses of blood are due to the natural response of the host defense mechanism against foreign surfaces. Inadequate control by natural inhibitors results in pathological processes, such as microthrombi generation or thrombosis, iao complications, hemodynamic instability, fever, edema, and organ injury.

Basic research Still having a strong connection with academia, HaemoScan is committed to advancing the Blood-Biomaterial interface research and hemocompatibility testing.

The model has a low background for thrombosis. Application of biomaterials in direct blood contact results in activation of the blood coagulation system and in an inflammatory reaction. Worldwide Standards We can source any standard from anywhere in the world. In recent years it has done so by reviewing literature and identifying the obstacles of hemocompatibility testing [1] and by describing the state-of-the-art blood—biomaterial interface research [2].

References [1] van Oeveren W. Given the disadvantages of animal models, such as higher costs, more variability, more time consuming, and insensitivity due to overwhelming short-term effects of tissue injury, in vitro blood flow models are more attractive.

Testing should be performed for five categories, based on primary processes: Biological evaluation of medical devices—Part 4: Selection of tests for interactions with blood Status: Test laboratories and medical devices manufacturers. No blood-air interaction as is the case in the Chandler model.

To assess hemocompatibility, blood flow models are often used and can either consist of in vivo animal models or in vitro blood flow models. Overview Product Details What is this standard about?

BS EN ISO 10993-4:2017

We perform in vitro tests with fresh whole human blood to determine the hemocompatibility of materials, devices, or material 1099-4 using our unique blood circulating model Haemobile.

Please download Chrome or Firefox or view our browser tips. We offer hemocompatibility testing in accordance with ISO As one of our experts, Dr Wim van Oeveren, is a member of the ISO committee that drafts and revises the ISO standard, we are very well qualified to help you perform hemocompatibility testing to achieve CE or FDA certification regarding blood compatibility.

Search all products by. This includes a more current description of in vitro techniques that rely less on the use of animals and generate more predictive results. Stirred, shaken, or stagnant: We are specialized in assessing blood compatibility.

In this system all relevant aspects of blood activation are taken into consideration, but, and this is most important, testing should simulate clinical conditions as much as possible. Selection of tests for interactions with bloodcan be used as a directive 10993- evaluate these hemocompatible characteristics. The importance of fresh blood. Obstacles in haemocompatibility testing.
