Structure of  Hydrocolloid dressing:

Hydrocolloid dressing is a kind of elastic dressing made of medical hot-melt adhesive with CMC (carboxymethylcellulose) hydrophilic granules.

Specification of Hydrocolloid dressing:

Properties:

1.The semi-permeable matte polyurethane or polyurethane foam to enhance the absorbency.          Film thickness:0.025 to 0.035mm.

2.When the thickness of hydrocolloid dressing is 0.4mm, the properties is as below:

Moisture permeability: 0.34g/10cm²/24h/37ºC

                                       1.06g/10cm²/72h/37ºC

Hygroscopic ability:      2.4g/10cm²/24h/37ºC

                                        2.46g/10cm²/72h/37ºC

Hygroscopic capacity: 2.74g/10cm²/24h/37ºC

                                        3.52g/10cm²/72h/37ºC

                                        (ONLY FOR REFERENCE)

3.Hygroscopic capacity:2.83g/24h/37ºC

                                          3.23g/72h/37ºC

                                         (ONLY FOR REFERENCE)

4.PH5.7 Acid&Alkali resistance PH3 to PH12.5.

5.Hygroscopic capacity and hygroscopic capability can b adjusted according to need.

Features:

1.Excellent exudates absorption capability.

2. Keep the wound in a moist enviroment, promote wound healing, effectively release pains and reduce change frequency of wound care dressing.

3.Waterproof, breathable, protect the wound from microbial invasion.

4.Excellent elasticith and self-adhesive,comfortable and convenient to use.

5.Change the dressing when it turns white.

6.Easy to peel off, no adherence to wound,effectivly reduce the potential damage and pains.

7.Available in different sizes and shapes to meet the clinical needs.

Application:

For slight or moderate exudating  wounds.

1.Leg ulcer.

2.degree bdsores.

3.Superficial and burn wound.

4.Post-operation wound.

5.Skin-donor sites.

6.All kinds of superficial wound and cosmetic wound.

7.For granulation and epithelialisation process of chronic wound.

Notice:

1.Make sure the wound area is clean and dry before using the dressing.

2.Hydrocolloid dressing should b 2cm bigger than the wound area to make sure that dressing can cover the wound.

3.If the depth of wound is more than 5mm, it is better to fill the wound with proper material before using the dressing.

4.It is not suitable for wounds with heavy exudates.

5.When the dressing becomes white and swelling, it indicates that dressing should be changed.

6.At the very beginning of the using the dressing, wound area may be enlarged, this is caused by the debridement function of the dressing and it is normal phenomenon.

7.The gel will be formed by the mixture of hydrocolloid molecule and exudates. As it looks like purulence secretion, it would be misunderstood as the wound injection. Just clean it with saline.

8.There maybe some smell from the dressing sometimes, and this smell disappear after cleaning the wound with saline water.

9.Dressing should be changed at once leakage occured around the dressing.
