检修 (jiǎnxiū) is a compound verb meaning 'to inspect and repair' — it combines 检 (jiǎn, 'to inspect, examine') and 修 (xiū, 'to repair, fix'). The two characters function equally and inseparably: the action always involves both checking for problems *and* carrying out necessary repairs. It emphasizes a systematic, often preventive or routine maintenance process rather than emergency fixes.

This term is commonly used in technical, industrial, medical, and infrastructure contexts — for example, when referring to scheduled maintenance of machinery, hospital equipment, elevators, railway systems, or electronic devices. While it can apply to everyday objects, it carries a formal, professional connotation and rarely appears in casual conversation about personal belongings. In healthcare settings, 检修 frequently describes the regular servicing of diagnostic tools like MRI machines or ventilators to ensure accuracy and safety.
