A breast shield for a breast pump for expressing human breast milk has a funnel (11) for bearing against the human mother's breast, and also has a connection part (10), wherein the funnel (11) widens in the direction of the mother5s breast and encloses at least a nipple and an areola surrounding the nipple. The funnel (11) has an end which is directed towards the breast and forms a lay-on edge (12) for providing contact with the mother's breast. The breast shield has a through-passage (14) which extends from that end of the funnel (11) which is directed towards the breast to that end of the connection part (10) which is directed away from the breast, and which serves for applying a negative pressure to the mother's breast and for the outflow of pumped-out breast milk. The lay-on edge (12) of the funnel (11) is formed by a three-dimensional curve, which is not located in a single plane, wherein the funnel (12) has at least two planes of symmetry (S1, S2). The breast shield according to the invention can butt against the mother's breast in a manner which provides optimal sealing and is comfortable for the mother.一種供用於吸出人類母乳之吸乳泵用的乳房護罩具有用於靠在人類母親的乳房上之漏斗(11)，且亦具有連接部分(10)，其中漏斗(11)在母親的乳房之方向上加寬且圍封至少一乳頭及包圍乳頭之乳暈。漏斗(11)具有一末端，該末端朝著乳房定向且形成用於提供與母親的乳房之接觸之貼放邊緣(12)。該乳房護罩具有貫穿通路(14)，該貫穿通路自漏斗(11)的朝著乳房定向之末端延伸至連接部分(10)的遠離乳房定向之末端，且用於施加負壓力至母親的乳房及用於使泵出的母乳流出。漏斗(11)之貼放邊緣(12)係藉由不定位於單一平面中之三維曲線形成，其中漏斗(11)具有至少兩個對稱平面(S1、S2)。根據本發明之乳房護罩可以提供最佳密封且對母親而言為舒適的方式與母親的乳房相連。
