Testing for Biomedical Applications

In order to categorize the testing needs of this industry, it is useful to divide it into three broad classes: in vivo, durable goods and disposables. The kinds of data needed for each situation are quite different

Biomedical applications for use inside the human body are characterized by the need for properties measured in a fluid environment and at body temperature. Aside from metals, the properties of most materials are surprisingly different at 37C as compared to room temperature. It becomes important to measure all relevant properties for in-vivo applications at this temperature. If materials are immersed, then testing in a saline environment at 37C is required.

Durable biomedical goods need to characterized for mechanical properties as well as for processability. CAE is often used in such applications, including injection molding simulation and FEA for structural integrity and creep studies. Long term effects are important and in some cases, the ability to withstand impact. Foams are used in many components and the complex short term and long term properties are needed for good design.

Disposable ware is used extensively in the medical industry. Design is primarily with plastics and rubber. New age drug delivery products and the resultant need for high reliability operation has converted this industry segment into a high-technology environment. Injection molding simulation and non-linear finite element analysis are commonly used.
