substances used by health care providers to provide lubrication and lessen discomfort to the patient during certain medical and surgical procedures such as vaginal or rectal examinations
外科用潤滑劑（Surgical lubricants）或醫療用潤滑劑（medical lubricants）是醫護人員在進行一些檢查或是手術（例如陰道檢查或是）時，提供潤滑及減少病患不適的物質。另外，進行超聲波檢查時亦會用上，因為聲波在液體的傳播能力比空氣中強，在檢查前先在皮膚表面塗抹潤滑劑，潤滑劑可填補皮膚與超聲波探頭之間的空隙，可提高檢測的準確度及清晰度。
