A wearable breast pump system is provided. The wearable breast pump system can include a housing having a pump, a breast flange, and a milk container. The pump can form part of a closed loop system that drives a separate, deformable diaphragm to generate negative air pressure. The diaphragm can be removably mounted on a breast shield.

The invention is a wearable breast pump system including a housing shaped at least in part to fit inside a bra and a piezo air-pump. The piezo air-pump is fitted in the housing and forms part of a closed loop system that drives a separate, deformable diaphragm to generate negative air pressure. The diaphragm is removably mounted on a breast shield.

Systems and methods for pumping milk from a breast responsive to a controller, wherein the milk is expressed from the breast under suction and milk is expulsed from the pumping mechanism to a collection container under positive pressure.

The present invention relates to an expression kit (2) for a breast pump (1) for extracting breast milk (101) from a human teat (102). The expression kit (2) comprises: a breast pump body (10) comprising a first pressure chamber (11) and a second pressure chamber (21); wherein the first pressure chamber (11) is configured for connection to a pressure unit (30) for generating a in the pressure chamber (11); wherein the second pressure chamber (21) comprises a breast-receiving funnel (22), a milk outlet (23) and a milk path (24) from the breast-receiving funnel (22) to the milk outlet (23); and wherein the first and the second pressure (11, 21) chamber are separated by a breathable membrane (50), which is gas-permeable and liquid-impermeable, for separating the first pressure chamber (11) from liquid in the milk path (24), wherein the breathable membrane (50) is a hydrophobic membrane. Further, the present invention relates to a breast pump (1).

An electrical breast pump (10) comprising a vacuum source (100) having a vacuum pump (120) with an electrical motor (121) and an aerate valve (150) is provided. Furthermore, a controller (110) controls an operation of the vacuum (120) and the aerate valve (150). Each pumping cycle comprises a pumping period (PP) of the vacuum pump (120) and an aerate period (AP) during which the aerate valve (150) is switched on and the vacuum pump (120) is in active and the electrical motor (120) is switched off. A drive circuit supplies a motor supply voltage for the electrical motor (121) under the control of the controller (110). The drive circuit (140) detects an electromotive force induced voltage at the electrical motor (121) when the motor supply voltage is switched off. The controller adapts the control of the operation of the vacuum pump (120) based on the detected induced voltage.

A system for synchronizing one or more breast-pumping sessions of an individual (such as a mother) and milk consumption by a second individual (such as a baby or infant) is described. In particular, based on measurements of a volume of the collected milk as a function of time and received information specifying milk consumption by the second individual as a function of time, a control circuit may determine a need for milk. Then, the control circuit may provide feedback based on the determined need for milk that synchronizes the one or more breast-pumping sessions and the milk consumption. For example, the feedback may alert the individual to initiate a breast-pumping session and/or may provide a signal to a breast pump that initiates a breast-pumping session.
