Products Description
The core function of silver alginate dressing
1. Enhanced antibacterial effect
Broad-spectrum sterilization
Silver ions (Ag⁺) destroy bacterial cell membranes (bind to -SH groups) and inhibit DNA replication (block DNA helicase), and the sterilization rate for MRSA, Pseudomonas aeruginosa, Candida, etc. is >99.99% (24-hour contact test).
Sustained antibacterial
Sodium alginate fiber slowly releases silver ions (0.5-1.2μg/cm²/day), and the antibacterial activity is maintained for 7-14 days (ordinary silver dressings only 2-3 days).
2. Optimization of exudate management
Ultra-high absorption
It can absorb 20-25 times its own weight of exudate (ordinary alginate is 15 times), and locks in liquid after gel conversion without reverse osmosis.
3. Promote healing
Anti-inflammatory regulation
Angiogenesis
2. Contraindications
Absolute contraindications:
Allergy to silver (positive patch test)
Pregnant women (fetal nervous system development period)
Relative contraindications:
Hypoproteinemia
Usage specifications and techniques
1. Standard operating procedures
Pretreatment for debridement:
Filling method:
Cavity wounds: Loosely fill to 80% volume, avoid excessive compaction
Plane wounds: Covering thickness 2-3mm, 1.5cm beyond the wound edge
Silver alginate dressings have become a revolutionary solution for complex infected wounds through the triple mechanism of precise antibacterial, intelligent exudate management, and synergistic healing. Compared with ordinary dressings, it significantly improves the efficiency of infection control and accelerates the process of tissue repair.
