Hemocompatibility of blood contacting medical devices has to be evaluated before their intended application. In recent years it has done so by reviewing literature and identifying the obstacles of hemocompatibility testing  and by describing the state-of-the-art blood—biomaterial interface research .
Why should you use this standard?
Find Similar Items This product falls into the following categories. Blood compatibility relates to specific interactions between bio materials and circulating blood.

Hemocompatibility testing (ISO )
The importance of fresh blood. These responses of blood are due to the natural response of the host defense mechanism against foreign surfaces.

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. This uso a more current description of in vitro techniques that rely less on the use of animals and generate more predictive results. Overview Product Details What is this standard about?

In vitro blood flow model with physiological wall shear stress for hemocompatibility testing-An example of coronary stent testing. No blood-air interaction as is the case in the Chandler model. Pulsatile flow with physiological wall shear stress.
The standard is applicable to external communicating devices, either with an indirect blood path e.
Application of biomaterials in direct blood contact results in activation of the blood coagulation system and in an inflammatory reaction. Take the smart route to manage medical device compliance.
We are specialized in assessing blood compatibility. Obstacles in haemocompatibility testing. Please feel free to contact us to see if we can be of assistance to your project.
Testing should be performed for five categories, based on primary processes: Stirred, shaken, or stagnant: Besides intrinsically driven research we perform basic contract research, which varies from simple hemolysis testing to custom build in vitro blood flow models. Io offer hemocompatibility testing in accordance with ISO What goes on at the blood-biomaterial interface.
Selection of tests for interactions with bloodcan be used as a directive to evaluate these hemocompatible characteristics. Moreover, sio have investigated the necessity of using fresh blood for hemocompatibilty testing is and have developed our own in vitro model for hemocompatibilty testing which utilizes pulsatile flow and physiological wall shear stress . These adverse events can manifest themselves during prolonged and intensive foreign material contact, such as vascular implants and extracorporeal blood circulation.
The version was updated to match the current tools and techniques used to evaluate medical device blood material interactions.
