The invention relates to a breast shield unit for use in a device for expressing human breast milk using a vacuum, having a breast shield body (1) with a first opening for receiving a nipple of a mother's breast and with a second opening as a discharge for expressed breast milk. The breast shield unit further has a media separating device (3) which separates expressed milk from a vacuum source and which is arranged in the breast shield body (1), said media separating device (3) having a through-channel which connects the first opening of the breast shield body (1) to the second opening of the breast shield body (1). The through-channel has a passage opening (35) which can be enlarged by externally applying a vacuum. The passage opening (35) is formed by walls (36) which can be moved away from one another in a manner which is approximately free of elongation when the vacuum is applied externally in order to enlarge the passage opening (35). The breast shield unit according to the invention allows a separation of media with a minimal dead volume and optimized comfort for the mother. |
