Embodiment Construction

[0016] A medical silicone gel dressing, characterized in that it consists of drug-containing silicone gel gauze 1, polyurethane foam 2 and pressure-sensitive adhesive polyurethane film backing 3, see the attached figure 1 . The medicated silicone gel gauze 1 is prepared by coating the medicated silicone gel 11 with the degreased gauze 12. The degreased gauze 12 has uniform holes 13 to facilitate the drainage of chronic wound exudate. For the specific structure, see the attached figure 2 , the drug-containing silicone gel 11 is prepared by mixing production factor (rhEGF) freeze-dried powder and silicone gel, adding an appropriate amount of production factor (rhEGF) freeze-dried powder can improve the healing speed of chronic wounds, and silicon Gel gauze 1 has the characteristics of flexible adhesion, and when in contact with chronic wounds, it will not destroy the healing environment of the wound and reduce the secondary damage of the wound. The polyurethane foam 2 is a kin...

Abstract

The invention relates to a medical silica gel dressing. The dressing comprises drug-containing silica gel gauze, polyurethane foam and pressure-sensitive adhesive polyurethane film backing. The method is simple in process, and the manufactured medical silica gel dressing has the characteristics of high healing speed, small wound secondary injury and the like for chronic wounds, can be used for greatly reducing the working intensity of medical staff, can be easily processed in a large scale due to developed production equipment and the like, and is convenient for industrial popularization and application.

Description

technical field [0001] The invention relates to a medical silicone gel dressing and a manufacturing method thereof, in particular to a medical silicone gel dressing for chronic wound care and a manufacturing method thereof. Background technique [0002] Medical silicone gel dressing is a new type of functional dressing. It is mainly used in the care of chronic wounds such as bedsores and pressure sores. Because chronic wounds are difficult to heal and easily cause secondary damage, traditional medical dressings can no longer meet the clinical nursing requirements. Therefore, it is necessary to design and develop a novel medical silicone gel functional dressing to solve the above clinical problems. [0003] Aiming at the characteristics of chronic wounds, the present invention provides a new type of medical silicone gel dressing and its manufacturing method, which solves the shortcomings of the existing traditional dressings that have a long healing period and is easy to caus...
