Abstract
A method of cleaning an aspiration tube in a specimen measuring apparatus includes: moving the aspiration tube while discharging a cleaning liquid onto an outer side surface of the aspiration tube; stopping the aspiration tube in a state where a tip of the aspiration tube or a droplet attached to the tip contacts a surface of a flow of the cleaning liquid; and moving the stopped aspiration tube in a direction away from the surface of the flow of the cleaning liquid.
