Traditional wound dressing with gauze, cotton and other natural materials, but the resulting wound adhesion often makes the patient suffering in dressing change. Recently, a new type of highly absorbent drug sustained-release hydrogel wound dressing Soochow University successfully developed, so that such a scenario will not appear, can greatly reduce the pain of patients.

In charge of the project, Professor Yang Zhanshan of Soochow University School of radiation medicine and public health, introduction, compared with the traditional medical gauze, hydrogels, no adhesion with the wound, does not damage the epithelium and granulation tissue, easy replacement, patient comfort, has become the ideal choice for patients with burn wound and scald, the new century, bedsores and other skin damage.

As early as in 2001, they developed a hydrogel dressing has been a national patent and successful conversion, by patients and hospitals generally praised. A new medical high absorbent hydrogels at present project group developed, on the basis of existing products are improved, dressing thin air, the thickness of only 0.5~1mm, the hydrogel can easily observe wound healing. The hydrogels with high degree of swelling, liquid a palm size weighs only 10 grams of the hydrogels can absorb 500~700 grams, the patient whose time is prolonged from 5 days to 10~15 days, can absorb a lot of exudate in large area burn and produce, suitable for severe burn trauma patients, not only for patients to save the cost of treatment can also reduce the workload of doctors. In addition, a new kind of hydrogel membrane can release antibiotic and cell growth factor on wound healing, infection and has good curative effect, through comparative tests, the new hydrogel membrane can promote burn and refractory radioactive ulcer healing 8 days in advance. At present, this new type of highly absorbent hydrogel wound dressing preparation technology has been successfully applied for China and American invention patent.

It is understood that hydrogel wound dressing has been sold in foreign countries, but there are 80% of these hydrogel dressings have cytotoxic reaction, and the preparation process is complex, expensive. While the new hydrogel film developed by Soochow University through a series of tests, no toxicity to the body and cells, without skin irritation and sensitization. In the production process, a new type of hydrogel film can be automated production, radiation synthesis and sterilization at the same time, reducing the synthesis of products packaging sterilization process.

According to Yang Zhanshan introduction, the use of this new type of hydrogel drug delivery function, can be used in addition to burn and scald patients, which can also mixed with other substances to other functions, such as the incorporation of various cytokines such as water-soluble skin care essence made facial mask. In addition, the characteristics of the new kind of hydrogel international leading moisture absorbent performance and no harmful dust, can also be used in the development of children diapers and other products to plant trees in the desert in water.
