Connection of the Tubing.
The flushing medium enters the lumen of the uterus via a Foley catheter which is connected to one arm of a Y connector while the outflow tube, connected to the other arm of the connector, is clamped off. Once the uterus has been distended the inflow is clamped off and the clamp on the outflow tube is released. Shown is the black clamp on outflow tube
