Disclosed is a milk suction and collection device integrally manufactured and formed by silicone. The milk suction and collection device includes a main body which is hollow inside to define a milk storage chamber and is further provided with a milk pouring port operative to be selectively blocked. A breast protecting film is provided on a side in a thickness direction of the main body and is configured to be fitted with an outer periphery of a breast, and is further provided with a milk collecting port communicating with the milk storage chamber. The side of the main body of the milk suction and collection device provided with the breast protecting film is operative to be fitted with the breast because the milk suction and collection device is integrally manufactured and formed by silicone. When the milk pouring port is closed, a breast pumping function is achieved by squeezing the main body. When the milk pouring port is opened, a milk collecting function is achieved.

A breast pump milk flow rate sensor system and apparatus for accurately assessing both a flow rate and amount of milk expressed during a pumping session is provided. The breast pump milk flow rate sensor system and apparatus may be contained within a breast pump.

The invention relates to an apparatus (10) for collecting information related to operation of a breast pump device (1) comprising a pump (31) and a circuit (32) for supplying electric power to the pump (31). The apparatus (10) is accommodated in a power adapter of the device (1) and comprises a detection unit (11) that is configured to detect an electric signal on the circuit (32) of the device (1), a processing unit (12) that is configured to receive the detected electric signal from the detection unit (11) and to process the detected electric signal according to a preset routine in order to generate an information signal representative of information related to use of the device (1), and a transmission unit (13) that is configured to receive the information signal from the processing unit (12) and to transmit the information signal to an external device such as a smartphone (6).

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.

An electric breast pump 1 includes a breast placement part 12 in which a breast part including a breast and a nipple of a subject is placed and suction-pressure generating units 10 and 50 that generate a suction pressure in the breast placement part. The suction-pressure generating unit generates a suction cycle including a plurality of sucking operations. The suction cycle includes basic suction and increased suction with an increased suction pressure. A suction pressure difference that increases in the increased suction is a pressure difference at a borderline at which a user perceives a change of a suction pressure. In the suction cycle, the basic suction and the increased suction are each repeated multiple times consecutively at an equal suction pressure. At least a last sucking operation in the suction cycle is extended suction having a longer suction time than those of other sucking operations.

A pump arrangement (5) for use with abreast pump device comprises a pump element (51), an expression kit air conduit (55) designed to allow for air connection of an expression kit (2) of the device to the pump arrangement (5), a volume element (54) configured to store vacuum in the pump arrangement (5), and a storage switching mechanism (58) arranged between the expression kit air conduit (55) and the volume element (54), configured to switch between a position of direct connection of the expression kit air conduit (55) to the volume element (54) at a bypass position with respect to the pump element (51) and a position of disconnection of the expression kit air conduit (55) from the volume element (54). Through a direct exchange of vacuum between an expression kit (2) and the volume element (54), support of the functioning of the pump element (51) is realized.

The suction-pressure generating unit generates a suction cycle including a plurality of different suction pressures. The suction cycle includes basic suction, increased suction with an increased suction pressure, and reduced suction with a reduced suction pressure. A suction pressure difference between a suction pressure increasing in the increased suction and a suction pressure reducing in the reduced suction is an equal pressure and is a pressure difference at a borderline at which a user perceives a change of a suction pressure. In the suction cycle, the basic suction, the increased suction, and the reduced suction are each repeated multiple times consecutively at an equal suction pressure.
