Abstract: A breast interface (70) for a breast pump (1) includes a liner support frame (200) and a liner (100). The liner support frame defines an interior liner support frame space (202) configured to receive at least part of the liner (100). The liner support frame comprises a front ring (204) and a split rear ring (206) including at least two complementary circumferential rear ring portions (206a, 206b) that are rearrangeable relative to each other to facilitate passage of a flanged rear end of the liner (100). The liner (100) comprises a rear section (170) including a tubular wall part configured to be fittingly enclosed by the rear ring (206) and provided with a first annular flange (172) with an outer diameter that is greater than an inner diameter of the rear ring (206) of the liner support frame (200), and that, in an assembled condition of the breast interface, abuts the rear ring (206) on end.

Abstract: A liner (100) for use in a breast interface (70) comprises a front section (110) including a front wall part (112) defining a breast contact surface (118) and an opening (116b) provided in the breast contact surface. The breast contact surface (118) is configured to abut a woman's breast during use, while a nipple of the breast protrudes at least partially through the opening (116b). The breast interface further comprises a rear section (170), connected to the front section (140), that includes a tubular wall part (171) having a rear end opening. The front and rear sections (110, 170) together define a milk passage (190) that extends from the opening (116b) in the breast contact surface (118) to the rear end opening of the tubular wall part (171), wherein the milk passage slopes downwardly in the rearward direction.

Abstract: A pump having a substantially cylindrical shape and defining a cavity formed by a side wall closed at both ends by end walls wherein the cavity contains a fluid is disclosed. The pump further comprises an actuator operatively associated with at least one of the end walls to cause an oscillatory motion of the driven end wall to generate displacement oscillations of the driven end wall within the cavity. The pump further comprises a valve for controlling the flow of fluid through the valve.
