FoamD Ressing Technology

Hydrogel Dressing

Technology Introduction

At present,the dressings used for wound treatment in domestic hospitals are mainly traditional dry gauze & non-woven fabric, while more than 60% of hospitals in Europe and the United States use moisture wound dressings. Not only the healing speed of moisture dressing is 1.5 times of traditional gauze, but also reduce the patient's pain and fade scars.

As the aging of our country's population and economic development,the demands for advanced moisture wound dressings will increase accordingly.

Features:

1.Re-hydrate dry and necrotic tissues and promote autolytic debridement.

2. Maintain a moist environment and help accelerate wound healing.

3. Down pressure can elastically press granulation tissue on the side to prevent scar formation.

4. Transparent, waterproof and breathable, it is convenient for medical staff to observe the wound and also for patients to move freely.

5. As a drug carrier for external use, it cooperates with antibacterial and anti-inflammatory adjuvant therapy. 

FoamD Ressing Technology

The hydrogel dressing has down pressure to prevent scar formation, does not adhere to the wound, reduces pain, effective bacterial barrier , does not infect the wound, and the use of surgical tape will not affect the bathing. It has good air permeability and helps the wound to recover and inhibits the growth of scars.

FoamD Ressing Technology

After the wound is completely healed, use the Hydrogel Dressing: The dressing has strong downward pressure, which can press down to proliferate the scar on the surface of the skin, soften the scar and dilute the melanin deposit in the scar.

Indications: Suitable for mildly exuding wounds: such as mildly exuding wounds, such as burns, pressure ulcer, diabetic feet, arterial and venous ulcers, traumatic wounds, postoperative wounds, etc. 

Applicable departments: Emergency Department, Plastic Surgery Department, Endocrinology Department, General Surgery, Burns Department, General Anorectal Department, Brain Surgery, ICU, Orthopedics, Neurosurgery. 

It can be tailored to fit the size of the wound according to the needs of clinical use.

Biological principles of wound healing:

The process of normal wound healing is divided into three phases: the inflammation phase, the proliferative phase, and the remodeling phase.

The skin becomes inflamed after injury, so the inflammatory phase is a necessary process in wound healing; at this time, the permeability of blood vessels increases, and white blood cells such as phagocytic bacteria will migrate and gather, eat the necrotic tissue and bacteria, stop bleeding, and put it on the wound. It secretes secretions that promote healing. At this time, the wound will have redness, swelling, and heat; the normal wound healing (non-diabetic wound) inflammation period usually lasts three to four days and lasts up to one week. If the inflammatory period lasts too long (for example, the wound is infected with foreign bodies), the free radicals and peroxides in the wound will accumulate too much, which will hinder wound healing and enter the period of collagen production dominated by fibroblasts ( Proliferative period), and become a chronic wound.

Inflammation is an indispensable process of wound healing. What we can work hard is to keep the inflammation period from increasing. Therefore, in the face of inflammation symptoms, please don't be nervous! 

FoamD Ressing Technology

The first stage of inflammation: 

At this time, the wound will secrete tissue fluid to promote healing, and the amount of exudate in the wound at different stages of the healing process is also different; at the beginning of the inflammation stage, the increase in inflammatory mesons leads to vasodilation and increased permeability. , A large amount of intravascular fluid enters the interstitial fluid and then exudes from the wound. In the absence of bacterial infection, it is usually a medium-sized light yellow clear liquid (if the wound is infected with pus). At this time, the wound should be kept clean. Use normal saline to rinse, and choose a dressing that can absorb a large amount of exudate to cover the wound.

The second stage of proliferation: 

as the granulation tissue produces angiogenesis (dark red granulation tissue: increased blood vessel density), the amount of exudate is larger than the beginning, and then as the granulation tissue matures (light pink granulation tissue: blood vessel density decreases) and Gradually re-epidermis, the amount of exudate reduced to medium to low degrees. At this time, the wound should be kept at a proper humidity, and the wound should not be over-dried, and there is no need to change the dressing all the time.

The third remodeling period: At this time, the collagen becomes stronger, stronger, less capillary, and the color of the wound becomes lighter. The intensity of the wound will gradually become stronger in the next six months, and finally reach 70% of the strength of intact skin. . This period is when new skin and epidermal cells begin to perform epithelialization, and care must be taken to protect new tissues and inhibit scar formation.
