At the Wittenburg Group we have extensive experience with applications that come into contact with blood. Our Cawiton® Blood contact materials are developed with a broader focus than standard bio-compatibility; these materials have been tested according to the ISO 10993-4 standard on Hemo-compatibility.
ISO 10993-4:2017 specifies general requirements for evaluating the interactions of medical devices with blood. In an effort to harmonize biocompatibility testing worldwide, the International Standards Organization (ISO) developed a standard for “Biological evaluation of medical devices” (ISO 10993), it is currently a 20-part standard which is used to evaluate the effects of medical device materials on the body.
Examples of applications of our Cawiton® compounds are:
- Intravenous and subcutaneous catheters and tips.
- Wound care.
- Laboratory analytical labware.
- Blood transfer systems:
– Tubing for blood transfer.
– Seals and pump membranes.
– Blood heating systems and pressure regulators.
Please contact our engineers to solve your needs for blood contact certified TPE grades.
