    Abstract: A breast shield is provided that includes a hood body with an outer rim within which a breast is received and a shield extension portion extending downstream from the outer rim. A milk drain is connected to the shield extension portion. A vacuum isolation element including a collapsible membrane is connected to the shield extension portion of the hood body. The collapsible membrane portion includes an interior cavity communicating with the vacuum source. The interior cavity is effective to create a negative pressure within the shield extension portion when collapsed by vacuum to isolate the vacuum source from expressed milk, with milk being channelled through the insert to a collector, such as a milk bottle.
