Abstract
A breast shield has a tubular connector and a funnel that is integrally formed thereon, and is intended for resting on a mother's breast. The funnel widens toward the free side thereof which faces away from the connector. A passage, which extends continuously from a breast-side end of the funnel as far as a pump-side end, being opposite the breast-side end, of the connector, and serves to apply a vacuum to the mother's breast and for the flowing away of the expressed breast milk. The funnel is of more flexible design than the connector, and the funnel has a main region extending over a substantial part of the length thereof with a first opening angle of the passage, and a breast-side end region with a second opening angle of the passage. When not in use, the first opening angle is smaller than the second opening angle. In use, at least the first opening angle can be enlarged by axial pressure on the breast shield. The breast shield is pleasant to wear and minimizes the dead volume.
