Abstract
A breast shield unit of a breast pump for expressing human breastmilk includes a breast shield () to be placed onto a mother's breast, a breastmilk collection container () for receiving expressed breastmilk, an adapter () for connecting the breast shield () to the breastmilk collection container () and a valve head (). A breastmilk channel extends from the breast shield () into the breastmilk collection container () through the adapter () and the valve head (). The valve head () includes a valve () which closes and opens the breastmilk channel during the pumping action, wherein a fill level sensor () for measuring a fill level of the breastmilk collection container () is arranged in the valve head (). The breast shield unit according to the invention facilitates a fill level measurement without a structural change of the breast shield and breastmilk collection container. Moreover, it facilitates data interchange with external information storage and/or information processing units.
