‘刮擦’ (guā cā) is a compound noun meaning ‘scraping’ or ‘abrasion’—a minor injury where the outer layer of skin is rubbed or scraped off, often without bleeding. The first character 刮 means ‘to scrape’ (as with a knife or rough surface), and the second 擦 means ‘to rub’ or ‘to wipe’; together they emphasize friction-induced surface damage. It’s commonly used in medical, first-aid, and everyday contexts to describe superficial skin injuries caused by falls, brushes against rough objects, or accidental contact.

This term is neutral in register and appears frequently in health advisories, accident reports, and parental guidance. Unlike deeper wounds like cuts (割伤) or lacerations (撕裂伤), 刮擦 implies minimal tissue disruption—typically redness, slight swelling, or light flaking, but no open bleeding. It’s often paired with verbs like ‘造成’ (cause), ‘处理’ (treat), or ‘消毒’ (disinfect), and may be modified by adjectives like ‘轻微的’ (minor) or ‘轻微’ (slight).
