The present disclosure is directed to an improved electric breast pump performance by providing independent adjustment of pumping parameters, such as vacuum and cycle, among others, for each breast when double pumping. The electric breast pump provides the capability to independently select discrete values for each breast so that a separate setting can be set for vacuum and/or cycles or both and can be selected for each breast. These separate settings can be varied and adjusted independently. The improved breast pump can be operated to pump individual breasts, or both breasts simultaneously according to the setting. The improved breast pump utilizes data and information received from previous breast pump sessions to determine and provide improved and optimal settings for future sessions, thereby creating a more efficient breast pump system.

A barrier of a vacuum pump prevents contamination from entering a vacuum pump air line. The barrier separates parts of the pump and is moveable between an initial state and a distended state. The barrier is assembled within the pump with a pre-load. When the vacuum source is applied to the barrier, the barrier achieves a distended state and when the vacuum source is released, the barrier incrementally self returns to an initial state. The geometry and material construction of the barrier, along with the pre-load, assists in returning the barrier on its own to the initial state from the distended state.

A breast shield unit of a breast pump for expressing human breastmilk comprises a breast shield to be placed onto a mother's breast, a breastmilk collection container for receiving expressed breastmilk, an adapter for connecting the breast shield to the breastmilk collection container and a valve head. A breastmilk channel extends from the breast shield into the breastmilk collection container through the adapter and the valve head. The valve head includes a valve which closes and opens the breastmilk channel during the pumping action, wherein a fill level sensor for measuring a fill level of the breastmilk collection container is arranged in the valve head. The breast shield unit according to the invention facilitates a fill level measurement without a structural change of the breast shield and breastmilk collection container. Moreover, it facilitates data interchange with external information storage and/or information processing units.

A breast pump for collecting breast milk having a funnel intended to receive the breast, a housing and a device for producing a negative pressure. The funnel consists of a flexible material and extends into the housing. The device for producing a negative pressure has at least one body that is movable over a portion of the length of the funnel while compressing the funnel.

A breast pump is disclosed. According to an aspect of the present invention, there is provided a breast pump comprising a contact housing comprising a protruding part configured to correspond to a mother's nipple and extend toward the front; a first space-defining member coupled to the protruding part to define a first inner space; a second space-defining member defining a second inner space linked with the first inner space; a storage housing comprising a coupling hole corresponding to the second inner space, the storage housing being coupled with the contact housing; a lid coupled to cover the second inner space through the coupling hole of the storage housing, the lid comprising an air passage; a flow separation membrane configured to divide and separate the second inner space into a first portion and a second portion, the first portion linked with the first inner space, the second portion linked with the air passage; and an attachable pump module on the lid to suck air of the second portion through the air passage, wherein the attachable pump module is integrally coupled with the lid to be attached to and detached from the coupling hole.

Complexity of a process of mounting a cushion (40) to an air passage element (20) of abreast pump device is decreased by only requiring a user to arrange the cushion (40) on the air passage element (20) in a first arrangement in which the cushion (40) is easily accessible. Particularly, the user does not need to perform cumbersome actions aimed at accurately putting the cushion (40) to an intended, correct position, as a predetermined mounting arrangement of the cushion (40) on the air passage element (20) is realized under the influence of underpressure prevailing at a back side of the air passage element (20). In the process, the cushion (40) is put to the predetermined mounting arrangement, wherein the cushion (40) is made to flex and/or move.

A leak guard for use with a breast pump suction flange having a liquid extraction port through which liquid from a wearer's breast flows when the breast pump suction flange is worn by a wearer includes a flexible body defining an outer perimeter of the flexible body. The flexible body is configured to contact an exterior of the breast pump suction flange and substantially conform to an exterior contour thereof when worn. A liquid collection region defined by the flexible body within the outer perimeter is positioned beneath a bottom perimeter of the breast pump suction flange when the flexible body is worn to collect liquid leakage from the bottom perimeter.

An apparatus for biomimetic expression of breast milk can comprise a breast interface having an expandable membrane configured to mimic the geometry of an infant's mouth. Various regions of the expandable membrane may be configured to simulate the structure and/or function of various parts of an infant's mouth. The expandable membrane may comprise one or more of a distal sealing region configured to simulate the lips, a superior region configured to simulate the hard palate, an inferior protruding region configured to simulate the gums, an intermediate curved region configured to simulate the tongue, and one or more internal expansion regions configured to simulate the soft palate and the throat. The expandable membrane may have a varying thickness throughout the one or more various regions to enable movement of the regions similar to the movement of the corresponding regions of an infant's mouth during nursing.

A personal accessory kit (PAS) for a breast pump is provided. The PAS and breast pump together form a complete breast pump system. The PAS has a locking mechanism to lock a diaphragm base of the system to a cap of the diaphragm of the system. The PAS further has an ergonomically-shaped handle. A flattened port adapter plug is provided for reducing single pumping vacuum pressure when a single port of the breast pump is used. The adapter allows for the safe utilization of a single port of a breast pump.

A breast shield unit of a breast pump for expressing human breastmilk includes a breast shield (1) to be placed onto a mother's breast, a breastmilk collection container (5) for receiving expressed breastmilk, an adapter (2) for connecting the breast shield (1) to the breastmilk collection container (5) and a valve head (4). A breastmilk channel extends from the breast shield (1) into the breastmilk collection container (5) through the adapter (2) and the valve head (4). The valve head (4) includes a valve (40) which closes and opens the breastmilk channel during the pumping action, wherein a fill level sensor (6) for measuring a fill level of the breastmilk collection container (5) is arranged in the valve head (4). The breast shield unit according to the invention facilitates a fill level measurement without a structural change of the breast shield and breastmilk collection container. Moreover, it facilitates data interchange with external information storage and/or information processing units.
