Wolaid ETO Sterile gauze swabs are designed for wound dressing in minor injuries such as cuts, grazes and abrasions to provide cushioning support. They are soft, strong and highly absorbent. Sterile gauze is useful in blood collection as they provide a clean surface to apply pressure to the venipuncture site once the needle has been removed. They can also be used to absorb and clean up any small blood drops if any leaks have occurred during tube changing. It can be used on open wounds, as they are sterile and minimize the risk of infection. The wounds are dressed in nonadherent dressing, gauze, and a mild compressive dressing. They are meant for single use only and to be disposed of after the usage.
