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.

A single breast pump device (1) is adapted to enable realization of at least two batches (A, B) of breast milk as a direct result of a single pumping session to be performed on at least one user's breast, which batches (A, B) are different as far as the value of at least one quality parameter of the breast milk is concerned. The single breast pump device (1) comprises a detection unit (50) for performing real-time detection of the at least one quality parameter in a flow of breast milk and outputting a detection signal representing an actual value of the at least one quality parameter, and further comprises a controller (70) for receiving the detection signal from the detection unit (50) and using the signal in a process of determining an appropriate setting of the single breast pump device (1) as far as the choice of a destination position of the milk is concerned. A double breast pump device (2) is also disclosed.

The systems, methods, and devices can efficiently express breast milk while being visually and audibly discreet, and portable. The breastmilk expression system for extracting milk from a breast of a female may include an interface configured to deliver suction to a nipple of the breast. The system may include a breastmilk storage container configured to store breastmilk The system may include a control device operatively coupled to the breastmilk storage container and the interface. The control device may include one or more pressure reservoirs configured to store negative pressure. The control device may be configured to cause passive suction at the interface to cause extraction of the breast milk by controlling delivery of the negative pressure stored in the one or more pressure reservoirs to the interface.

The present invention relates to a pump arrangement (1) for a double breast pump (2). The pump arrangement (1) comprises first and second terminals (23, 24) for connecting first and second expression kits (3, 4) having first and second breast shields (5, 6) and at least one container (7) for collecting breast milk (8) in fluidic connection with the expression kits (3, 4), a pump (9) for generating reduced pressure within said breast shields, a plurality of conduits (10, 11, 14, 15, 16), a suction valve (12) connected to the pump (9) by a connection conduit (14) and to the first and second terminals (23, 24) by respective air conduits (10, 11), and a venting valve (13) connected to the first and second terminals (23, 24) by venting conduits (15, 16), wherein the venting valve (13) comprises an opening (17) to the environment. The pump (9) is alternatingly connected to the first and second terminals (23, 24) by alternate opening and closing of the suction valve (12) and the venting valve (13).

A breast pump device (1) comprises an expression kit (2) and a vacuum unit (3) configured to realize a pressure cycle in the expression kit (2). For the purpose of determining one or more milk expression characteristics such as total volume of expressed milk, the device (1) is equipped with an acoustic milk expression assessment system (6) including an acoustic sensor (61) and a processor (62) configured to process an acoustic signal received from the sensor (61) during operation of the device (1) when a receptacle (4) is used with the device (1) for receiving expressed milk. By recording sound during a pumping session, it is possible to determine a value of a time duration of a free fall of droplets of expressed milk from the expression kit (2) to the receptacle (4), which can be taken as a measure of a number of interesting milk expression characteristics.

Systems and methods for pumping milk from a breast, 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. In one approach, the breast pump assembly includes a breast adapter and a receptacle configured to cup the breast adapter, and the breast adapter is removable from the receptacle.

The present invention relates to a pump unit for a breast pump for extracting milk from a human breast, comprising a motor for driving the pump unit, wherein the motor is configured to provide a motor feedback signal; a control unit for providing a control signal for controlling the motor; and an estimator for estimating a pressure provided by the pump unit based on the motor feedback signal and the control signal; wherein the control unit is configured to adjust the control signal based on the estimated pressure.
