A breastmilk channel extends from the breast shield (1) into the breastmilk collection container (5) through the adapter (2) and the valve head (4). The valve head (4) comprises a valve (40) which closes and opens the 10 breastmilk channel during the pumping action, wherein a fill level sensor (6) for measuring a fill level of the breastmilk collection container (5) is arranged in the valve head (4). 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 15 units. (Figure 1)1/2 20 a B 3 4I 4 c 9 7--7 8I 242 80 6 40 40 5 d, 8 60 R P FIG.I1
