Material Performance Testing

Wound Care

Nelson Labs Bozeman has worked with wound dressings for more than 20 years. We offer a way to sell your products for more bottom-line profit to you. We evaluate several different kinds of wound dressings, including the following:

• Wounds dressings that absorb exudate
• Wound dressings that maintain moisture
• Wound dressings that supply moisture for debridement

We also evaluate antimicrobial properties for the wound dressings listed above.

These studies are not conducted for approval processes, but rather to sell your product’s strengths.

Our wound-care services include the following:

Bandage and Wound Care Absorbency Testing: We possess the equipment and facilities to evaluate the absorbency and vapor permeability of bandage and wound-care dressings.

Bandage Material Physical Properties: The Materials Testing Lab features temperature and humidity control along with the ability to test for tensile strength and peel adhesion. Our testing capabilities range from adhesive tape & wound care products to medical device packaging.

Hydration Property Testing for Wound Dressings: Studies using human subjects (intact skin) to determine the effectiveness of dressings in maintaining or augmenting skin hydration over time (e.g., alginates, foams, hydrocolloids, hydrogels, transparent films, etc.), with evaluation in terms of total moisture content of the skin.

Wound Healing Evaluations: Evaluations of the rate of cell proliferation, measured as a function of cellular protein expression (e.g., growth factors) in a 3-D model of wound re-epithelialization.

First Aid Wound Management: In-vitro evaluations, as described under II-A and as follows: 1) Screening zone-of-inhibition studies and 2) Studies per methodology prescribed by the FDA: 21 CFR Sections 333 and 369, “Tentative Final Monograph for Testing First Aid Antiseptic Products” (22 July 91).

In-Vitro Wound Management Evaluations: In-vitro evaluations of antimicrobial properties versus ATCC or clinically isolated strains of bacteria relevant to surgical-, burn-, and catheter-related infections. These include the following:

• Time-kill kinetic studies (planktonic and biofilm phases).
• MIC/MBC studies (planktonic and biofilm phases).
• Studies per AATCC Test Method 100 for assessment of antibacterial finishes (planktonic phase).
• Custom method development for non-standard products
