Leveraging Texture Analysis for Advancement: Testing Critical Material Attributes of Medical Devices

In the realm of medical device research and development (R&D), the Texture Analyser emerges as a pivotal tool, enabling comprehensive evaluation and enhancement of critical material attributes. Let’s explore its versatile applications:

The analysis of tensile strength offers profound insights into the robustness and elasticity of flexible medical devices such as sutures, catheters, and more.

Adhesion strength assessments extend to adhesive medical products, including wound dressings and patches, facilitating a nuanced understanding of bonding capabilities.

The Texture Analyser’s applicability encompasses the examination of compression and hardness, vital for implants and padded devices, elucidating resistance to compressive forces and hardness characteristics.

Evaluations of needle penetration dynamics measure the force requisite for needle penetration through skin or tissues, particularly relevant for devices like syringes. The assessment of puncture and burst resistance extends to products like gloves, pouches, or bags, gauging the force they can endure before puncturing or bursting.

The Texture Analyser’s contributions further include shear resistance testing, which informs the response of materials or devices to shear forces, relevant for products that might encounter sliding or rotational forces.

For drug-eluting devices, the analysis of release force offers insights into the required force or pressure for drug release.

The assessment of frictional properties is pertinent for devices like catheters, ensuring efficient navigation through bodily tissues.

Additionally, the Texture Analyser extends its functionality to evaluate gel consistency and strength, particularly significant for hydrogel-based products and materials employed in diverse medical applications.

Swelling properties examinations delve into the behaviour of materials like hydrogels or other absorbent medical substances when exposed to fluids.
