The present invention relates to a smart breast pump with a massage course generating function including: a close contact unit attached to the user's breast; an expression unit for repeatedly producing expression pressures patterned by the user's input to control an internal pressure of the close contact unit; and a connection unit for connecting the close contact unit to the expression unit to have a relation with the production of the expression pressures in the close contact unit and the discharge of breast milk expressed, wherein through an input part mounted on the expression unit, any one of an expression mode for expressing the breast milk and a massage mode for massaging the breast is selected.

An improved breast pump flange assembly, flexible membrane and method of use are disclosed. In some embodiments, the breast pump flange assembly includes a flanged housing having an interior chamber extending therethrough. The flanged housing including an upper receiving portion having a first diameter, a substantially tubular middle portion having a second diameter, and a substantially tubular lower connecting portion having a third diameter. In some embodiments, the breast pump flange assembly further includes a flexible membrane having an opening extending therethrough. The flexible membrane having one or more support pad positioned at least partially around the opening of the tubular middle portion of the flanged housing. The support pad configured to simulate the sensation of a baby's mouth on a breast, causing the breast to be massaged by intermittent suction action produced by a breast pump.

A breast guard for use with a breast pump suction flange having an interior surface for placement against a wearer's breast and a liquid extraction port that extracts liquid from the wearer's breast includes a first liquid barrier in contact with the interior surface, a second liquid barrier in contact with the wearer's breast, and a third liquid barrier extending from the first liquid barrier to the second liquid barrier. The first liquid barrier, second liquid barrier, and third liquid barrier collectively form a liquid retention space that retains breast liquid therein. The breast guard may retain leakage and reduce irritation to the breast while breast pumping.

A breast pump funnel integral or engageable with a breast pump providing intermittent pumping for drawing breast milk into a connected container, the breast pump funnel having: an outer frame and an inner malleable liner located at least partially within the outer frame and, in use, forming a contact surface to the breast. The outer frame, the inner malleable liner or both form a continuous restricting funnel for receiving an intermittent negative pressure pumping.

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.

Examples disclosed herein are relevant to breast pumps. Disclosed examples include breast pumps that automatically adjust various pumping parameters based on data obtained from one or more sensors. The one or more sensors can produce data regarding an amount of milk expressed by a user. The adjusting of the pumping parameters can be configured to, for example, help the user efficiently express milk by utilizing a closed-feedback system that monitors the flow rate of the expressed milk.
