Collaborative gauze bandages make it easier and faster for the injured to self-dress their wounds. The design was inspired by a difficult process of self-dressing a wound. We have integrated the functions of glue stick, gauze bandage and scissors, so that people can complete the whole dressing process with one hand. In addition, it can also protect the gauze bandage from contamination and provide a sterile and safe storage environment. Most of the injured are not familiar with the dressing process and knotting techniques. We hope this product will guard the injured like a nurse. The overall shape of the collaborative gauze bandage adopts the round and friendly "water drop type", and soothes the anxious psychology of the injured with the gentle product design language. The surface of the product is micro-frosted to create a warm touch. The central circle part is placed with replaceable gauze bandage, and the corner part is placed with knife and glue to realize the division of functional areas and conform to the usage habits.
