摘要： 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).

摘要： The present application relates to a breast pump. The breast pump has a chamber (12) and a membrane (22). The membrane (22) is receivable in the chamber (12) to separate the chamber (12) into first and second spaces (23, 24). The membrane (22) is also deformable in the chamber in response to a reduction of pressure in the first space (23) to cause a reduction of pressure in the second space (24). A limiter (16) is in the chamber (12) against which the membrane (22) is locatable to limit deformation of the membrane (22).

摘要： A breast pump system includes a solenoid valve and a power source. The power source is arranged to supply electrical power to the solenoid valve so as enable the solenoid valve to move between first and second positions. The breast pump system also includes a controller configured to detect a change in inductance of the solenoid valve that is indicative of the solenoid valve moving from first to second position and a control action in which the vacuum pump is stopped.

摘要： The present application relates to a breast pump system. The breast pump system comprises a vacuum path for creating a pressure reduction on a breast. A pump unit generates and releases a pressure reduction in the vacuum path, and comprises a vacuum pump (20). A leakage aperture (60) is configured to allow a controlled release of a pressure reduction in at least part of the vacuum path so that the pressure reduction in at least part of the vacuum path is released in the event that the pump unit fails to release the pressure reduction in the vacuum path. The vacuum pump (20) has a discharge port (22) for discharging air drawn from the vacuum path, and the leakage aperture (60) is disposed proximate to the discharge port (22) so that airflow discharged from the discharge port (22) is directed over the leakage aperture (60).

摘要： The present application relates to a breast pump system comprising a vacuum pump, an actuator for driving the vacuum pump, and a power supply for supplying electrical power to a plurality of components including the actuator, and also to a method for use in such as system. An output voltage of the power supply is detected, and in response to the detected output voltage being less than a first threshold voltage, the supply of electrical power to a predetermined one of the plurality of components is suspended. Then, if the detected output voltage recovers to a level above a second threshold value, the supply of electrical power is resumed.
