Medical Grade HBP Silver Ion Cotton Mesh Dressing - Sustained Release Antibacterial for Infected Wounds & Ulcers

This Silver Ion Cotton Mesh Dressing is a high-performance antimicrobial wound care solution engineered with innovative Hyperbranched Polymers (HBP) Ag+ chelation technology—the gold standard for treating infected acute and chronic wounds. Specially designed for clinical use in hospitals, clinics and wound care centers, it is the ideal choice for managing venous leg ulcers (VLUs), pressure ulcers (PUs), diabetic foot ulcers (DFUs), 1st & 2nd degree burns, surgical wounds, traumatic abrasions and donor site care.

Crafted from soft, medical-grade cotton with a double warp and weft knitting process, the dressing features large mesh cells that enable efficient exudate drainage, preventing fluid buildup and bacterial overgrowth in the wound bed. The HBP Ag+ core technology chelates silver ions via functional groups and releases them in a controlled, sustained manner through ion exchange—ensuring long-lasting antibacterial activity without sudden release irritation to new granulation tissue. This non-antibiotic formulation forms a durable antimicrobial barrier on the wound surface, inhibiting a broad spectrum of common wound pathogens (including Staphylococcus aureus, Escherichia coli and Candida albicans) and eliminating the risk of bacterial resistance.

Infused with white petrolatum and paraffin oil, the dressing delivers superior anti-adhesion performance, allowing for painless removal and reducing secondary damage to fragile wound tissue. Sterile, single-use and easy to apply, it conforms perfectly to irregular wound contours and can be used as both a primary and secondary dressing for infected wounds of all sizes. For global distributors and clinical partners, we provide fully customizable packaging and a complete set of regulatory-compliant technical documents, supporting seamless local product registration and market access across the EU, Middle East, Asia, Africa and beyond.

For Clinical Professional Use (Hospitals/Clinics)

Adhere to strict aseptic technique throughout all application steps.

Disinfect the skin surrounding the wound with a medical-grade antiseptic, rinse thoroughly with sterile normal saline to remove debris and exudate, and pat the area completely dry.

Open the sterile packaging and remove the silver ion cotton mesh dressing; peel off the backing to expose the adhesive surface (for adhesive variants).

Place the dressing over the wound, ensuring full coverage of the wound bed and a 1-2cm extension onto healthy surrounding skin.

Press the dressing firmly onto the skin, starting from the center of the wound and working outward to the edges, to ensure optimal adhesion and contact.

Secure with a secondary dressing (e.g., gauze, non-woven bandage) if needed; adjust fixation based on wound location and exudate volume.

Change the dressing according to wound exudate amount and clinical condition (1-3 days for moderate exudate; daily for heavy exudate/infected wounds) or as directed by a physician.

For Clinical Post-Care (Under Professional Guidance)

Clean the wound with sterile normal saline and dry thoroughly as instructed by a healthcare provider.

Apply the sterile silver ion cotton mesh dressing to cover the entire wound surface.

Secure with a breathable, sterile secondary dressing and avoid tight wrapping that may impede circulation.

Follow the physician’s recommended dressing change schedule; do not reuse the dressing or adjust the application method without professional guidance.

Service Scope: Dressing customization, packaging design, local registration document preparation, regulatory compliance guidance

Q1: What is the difference between the oily and non-oily variants of this silver ion cotton mesh dressing?

A1: The oily variant (infused with white petrolatum/paraffin oil) is designed for low-to-moderate exudate wounds and provides enhanced anti-adhesion for fragile granulation tissue (ideal for ulcers, burns and donor sites). The non-oily variant is optimized for moderate-to-heavy exudate infected wounds, with improved mesh drainage to prevent fluid buildup. Both variants feature the same HBP silver ion sustained release antibacterial technology.

Q2: Can this dressing be cut to fit irregular wound contours (e.g., heel pressure ulcers, facial wounds)?

A2: Yes. The soft medical cotton mesh is easily cut with sterile scissors (aseptic technique required) to custom fit any irregular wound shape or size, with the dressing extending 1-2cm onto healthy skin for full antimicrobial protection. Cutting does not affect the silver ion sustained release performance or the dressing’s structural integrity.

Q3: How long does the HBP silver ion provide antibacterial activity on the wound surface?

A3: The advanced HBP chelation technology enables controlled, sustained silver ion release for up to 72 hours per dressing application, forming a long-lasting antimicrobial barrier on the wound bed. The actual duration may vary slightly based on wound exudate volume—heavier exudate may require more frequent dressing changes to maintain optimal antibacterial efficacy.

Q4: Is this silver ion cotton mesh dressing suitable for diabetic foot ulcers (DFUs)?

A4: Yes. It is a clinical-grade solution for mild-to-moderate infected diabetic foot ulcers with low-to-moderate exudate. The sustained release silver ion technology targets bacterial colonization (a key cause of DFU healing delay), while the anti-adhesion formula minimizes trauma during dressing changes (critical for diabetic skin with reduced circulation). For severe, necrotic or heavily exuding DFUs, use under the direct guidance of a diabetic wound care specialist.

Q5: Can this dressing be used as a secondary dressing for negative pressure wound therapy (NPWT)?

A5: Yes. The non-oily variant is recommended as a contact layer for NPWT for infected wounds with moderate exudate (e.g., surgical wounds, traumatic wounds). It provides a soft, antibacterial contact surface between the NPWT device and the wound bed, preventing tissue ingrowth and maintaining antimicrobial protection during negative pressure therapy. Follow the NPWT device manual and clinical physician guidance for application.

Q6: What storage conditions are required for bulk clinical procurement of this dressing?

A6: Store the sealed cartons in a cool, dry, well-ventilated clinical warehouse with a temperature of 15-25℃ and relative humidity<60%. Avoid direct sunlight, high temperature (＞30℃) and humidity (＞70%RH) to preserve silver ion activity. Stack cartons on pallets (avoid direct contact with the ground) and follow the "first in, first out" inventory principle; do not stack heavy objects on cartons to prevent packaging damage and loss of sterility.

Q7: Does the dressing require refrigeration for storage or transportation?

A7: No. This silver ion cotton mesh dressing is a room temperature-stable medical device—refrigeration is not required and may cause condensation (which affects packaging sterility). For international transportation (e.g., high-temperature regions like the Middle East), we recommend insulated shipping cartons to avoid prolonged exposure to extreme heat (＞40℃), which aligns with our storage condition guidelines.

Q8: Can you provide clinical trial data or case studies for this dressing’s efficacy on chronic ulcers?

A8: Yes. We provide a comprehensive Clinical Validation Report with in vitro antibacterial efficacy data and clinical case studies on venous leg ulcers (VLUs) and pressure ulcers (PUs) (including healing rate, exudate reduction and bacterial clearance data). For global distributors requiring additional clinical evidence for local registration, our R&D team can also provide customized test data and third-party clinical verification reports (per local regulatory requirements).

Q9: What is the lead time for bulk orders and custom packaging?

A9: For standard non-customized bulk orders (oily/non-oily variants, standard sizes), the lead time is 15 working days. For custom packaging/dressing orders (printing, sizes, variants), the lead time is 60 working days (no mold cost for standard customizations). For large hospital/institional bulk orders (≥500 cartons), we offer flexible lead time adjustments and priority production scheduling.

Q10: Do you provide training for clinical staff on the proper application of this dressing?

A10: Yes. For bulk clinical procurement by hospitals/medical institutions, we provide free online clinical application training (conducted by our wound care specialists) covering aseptic application, dressing change techniques, oily/non-oily variant selection and troubleshooting. We also provide a printable clinical application guide (multilingual) for on-site staff training and reference.
