Breast attachment

A breast pump assembly comprising:

• a rigid horn having a circular cup portion adapted for receiving and sealingly engaging with a breast and a cylindrical neck portion extending from the circular cup portion, the cylindrical neck portion having an inner surface and an outer surface;
• a breast pump insert secured with the rigid horn and having at least one circumferential groove disposed on the inner surface, wherein the breast pump insert is adapted for collapsing along the at least one circumferential groove;
• a suction pressure source in communication with the breast pump insert for exerting a suction pressure to enable the cylindrical portion to collapse along the at least one circumferential groove, whereby the cylindrical portion can move from an uncollapsed state having a generally circular cross-section to a collapsed state having a generally flattened oval cross-section so as to exert a massaging effect on the breast to express liquid therefrom;
• and
• a container for collecting liquid expressed from the breast.

A method of expressing milk from a human breast using a rigid horn, a breast pump insert secured to the rigid horn and having at least one circumferential groove and adapted for collapsing along the at least one circumferential groove, a suction pressure source in communication with the breast pump insert, and a container for collecting expressed milk from the human breast, the method comprising:

• placing the rigid horn in sealing engagement with the human breast,
• applying a suction pressure to the breast pump insert for enabling the cylindrical portion to collapse along the at least one circumferential groove, whereby the cylindrical portion can move from an uncollapsed state having a generally circular cross-section to a collapsed state having a generally flattened oval cross-section so as to exert a massaging effect on the breast causing expression of milk;
• and
• collecting the expressed milk in the container.
