Advanced Wound Dressings
In 1962, British scientist named Winter found “the therapy of moist”. It proved that by winter form the experiments that in a moist environment, the migration of epithelia cells and wound healing will be obviously speeded up, it is faster than the wounds in a dry with a moist environment. Due to this, “the therapy of moist” product with high technology adopt many kinds of new material to provide the wound with a moist environment, they are only absorb the exudation from the wound and reduce the maceration, but also keep the exudations in the slipcover so as to create a moist microenvironment for the wounds in some extent. The moist environment will greatly promote the cell proliferation and epithelia cell migration , which can accelerate the wound healing.
Wound Healing Principles in Moist and Closed Environment
Theory of therapy of the moist.
Keep microorganism separate from wounds.
Keep the wound in a moist, warm environment.
Promote the zymogenesis and activate the growth factor thus accelerate wounds healing.
Prove the micro-circulation of wound area, “wake up” its capacity of self-cleaning.
All kinds of cells (neutrophilic granulocyte) will be activated to kill the causative organisms.
Neovascularization and granulation formation will be accelerated when the co2 gas concentration increase.
Moist gelation formation on the surface of the wounds protect the cambium and reduce the irritation of nerve endings and pain.
Accelerate the wound clean and support granulation formation and epithelialisation.

ILLUSTRATION FOR USING ADVANCED DRESSINGS(FOR REFERENCE ONLY)
HYROCOLLOID DRESSING
Characteristics
1. Good absorbency for exudation from the wound.
2. Keep the wound moist and accelerate the wound healing; reduce the pain and avoid the secondary damage to the
wound.
3. Waterproof, permeable and prevent the wound from bacteria outside.
4. Excellent elasticity and self-adhesive, easy for application.
5. Change the dressing when it turns white.
6. Easy for peeling off and it will not stick to the wound and keep patients comfortable.
Application:low or moderate exuded wounds
Crura venous ulcer
I-II degree bedsores
Small superficial burn wound
Postoperation wounds
Donated skin area
Superficial wound and beauty operation wound
Period of granulation and epithelialisation of chronic wound
HYDROGEL DRESSINGS
Characteristics
1. Top-medical hydrogel cleaner contains more than 90% water. It provide the wound with moisture and absorb the
exudation;
2. Top-medical hydrogel cleaner can isolate, separate, clean all of putrescence and scab of the wound and effectively
accelerate the wound healing;
3. Improve granulation regeneration and accelerate the epithelia cell division and migration thus help wound healing;
4. Soft, comfortable and with good elasticity; it can minimize the pain and not stick to the wound thus avoid damage
to the wound again;
5. No break, no decompacting and no residua on the skin after absorbing the exudation from wounds;
6. Completely transparent, can observe wound situation directly;
7. Hydrogel dressings with PU film is permeable, waterproof, antibacterial, self-adhesive and easy to use.
Application:
All kinds of wounds with scars and putrescence.
Chronic wound, burn wound and donate area and acute skin injury wound and brush-burn wound etc.
ALDINATE WOUND DRESSINGS
Characteristics
1. Mixture of natural weaweed fibre with calcium ion, has good histo compatibility;
2. Gelization white contact with the exudation of wound and well protect and accelerate the wound healing;
3. Rapid absorb the exudation from the wound; soft and comfortable for the skin;
4. The release of calcium ion can activate thrombinogen and improve hemostasis;
5. No adhesive to wound, no residual on the skin.
Technical data
Good absorbency and gelation; Viscosity coefficient>800cp Ash<0.5%, fibre denier: 1.5D strength: 1.5g/D elongation at break>10%,
Water absorption>8-10; bacteriostasis ratio>80%;
Needle punctured nonwoven fabric and filling stripe can be provided.
Application:
1. Acute and chronic wounds and infected wounds;
2. Clearing the wound exudation and accelerate the granulation growth and help wound healing;
3. The alginate padding is used in the lacuna, antrum wounds, such as nasal cavity, anus and intestines.
FOAM DRESSING
Characteristics
1. High absorbency, greatly absorb the exudation from the wound.
2. Covered by PU film which can be waterproof and prevent the bacteria infection.
3. Create a moist environment and accelerate the wound healing.
4. Don’t stick on wound when changing the dressing, no pain.
5. Soft, comfortable, also can be used as pad.
6. Beside all above advantages, the silver ion foam dressing also has excellent antibacterial function.
Applications:
High exudation wounds, Eg. UIcers, bedsores, donated skin areas, burn hurt etc.
SILVER WOUND DRESSINGS
Characteristics
1. Good, long term antibacterial
2. Have effect to all kinds of bacterias and drug-fast bacterias.
3. Protect the wound and accelerate the wound healing.
