Overview Product Details What is this standard about? Pulsatile flow with physiological wall shear stress. Obstacles in haemocompatibility testing. No blood-air interaction as is the case in the Chandler model. Blood compatibility relates to specific interactions between bio materials and circulating blood. We are specialized in assessing blood compatibility. This includes a more current description of in vitro techniques that rely less on the use of animals and generate more predictive results.

What goes on at the blood-biomaterial interface. Test laboratories and medical devices manufacturers.

Hemocompatibility testing (ISO )

We use cookies to make our website easier to use and to better understand your needs. It is a specification stating general requirements for evaluating the interactions of medical devices with blood.

Selection of tests for interactions with blood Status: Application of biomaterials in direct blood contact results in activation of the blood coagulation system and in an inflammatory reaction. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3.

In this system all relevant aspects of blood activation are taken into consideration, but, and 109993-4 is most important, testing should simulate clinical conditions as much as possible.


Who is this standard for?

Selection of tests for interactions with bloodcan be used as a directive to evaluate these hemocompatible characteristics. Hemocompatibility of blood contacting medical devices has to be evaluated before their intended application. We perform in vitro tests with fresh whole human blood to determine the hemocompatibility of materials, devices, or material structures using our unique blood circulating model Haemobile.

The version was updated to match the 10993–4 tools and techniques used to evaluate medical device blood material interactions. Moreover, we have investigated the necessity of using fresh blood for hemocompatibilty testing [3] and have developed our own in vitro model for hemocompatibilty testing which utilizes pulsatile flow and physiological wall shear stress [4].

The standard is applicable to external communicating devices, either with an indirect blood path e. Please feel free to contact us to see if we can be of assistance to your project.

Hemocompatibility testing

Take the smart route to manage medical device compliance. In vitro blood flow model with physiological wall shear stress for hemocompatibility testing-An example of coronary stent testing. 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]. Basic research Still having a strong connection with academia, HaemoScan is committed to advancing the Blood-Biomaterial interface research and hemocompatibility testing.

These responses of blood are due to the natural response of the host defense mechanism against foreign surfaces. To assess hemocompatibility, blood flow models are often used and can either consist of in vivo animal models or in vitro blood flow models.

These adverse events can manifest themselves during prolonged and intensive foreign material contact, such as vascular implants and extracorporeal blood circulation. 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.

109993-4, shaken, or stagnant: 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 109933-4 to achieve CE or FDA certification regarding blood compatibility. In 109934- hemocompatibility testing: Low concentration of anticoagulatns, typically 1.

Testing should be performed for five categories, based on primary processes: Search all products by. The importance of fresh blood. Besides intrinsically driven research we perform basic contract research, which 109993-4 from simple hemolysis testing to custom build in vitro blood flow models.

Inadequate control by natural inhibitors results in pathological processes, such as microthrombi generation or thrombosis, bleeding complications, hemodynamic instability, fever, edema, and organ injury. Biological evaluation of medical devices—Part 4: Worldwide Standards We can source any standard from anywhere in the world. The model has a low background for thrombosis. We have developed our own in vitro blood flow model [4] which offers several important advantages: Your basket is empty.
