The present invention discloses a hands-free wearable breast pump which includes: a main pump body, a milk reservoir, a tee piece, an airbag and a duckbill valve. The main pump body is provided with a mounting cavity having an opening in a front end surface of the main pump body; the tee piece includes a first port, a second port for mounting the airbag and a third port for mounting the duckbill valve; the airbag is mounted to the second port; the duckbill valve is mounted to the third port; the milk reservoir is mounted to the tee piece or the main pump body; the duckbill valve is in fluid communication with the milk reservoir; the main pump body has at least one pushing and positioning structure formed in the mounting cavity; the tee piece is detachably mounted in the mounting cavity and abuts against the at least one pushing and positioning structure; and the tee piece is pushed upward by the at least one pushing and positioning structure to press an open end of the airbag tightly against a side wall of the mounting cavity. The hands-free wearable breast pump has the advantages of excellent sealing performance and convenient disassembly and assembly.

A breast pump assembly is disclosed. The breast pump assembly according to an aspect of the present disclosure may include: a breast pump including a contact housing with a backside recessed to wrap a breast and a storage housing coupled to the contact housing to define a breast milk storage space on a frontside of the contact housing, the breast pump being provided with a coupling cavity penetrating an upper portion of the storage housing; a stopper detachably coupled to the coupling cavity and provided with a first air pipe connector; an air pipe coupled to the first air pipe connector; and a pump cradle provided with a second air pipe connector to which the air pipe is coupled, wherein the pump cradle includes: a first case provided with the second air pipe connector, an insertion hole and an air passage connector; a first milking pump installed in the first case; a duct connecting the first milking pump and the air passage connector to the second air pipe connector; and a pump module including a second case detachably coupled to the insertion hole and a second milking pump installed in the second case, wherein the second case is provided with an air passage connecting the air passage connector with the second milking pump, and wherein the pump module is separated from the insertion hole and detachably coupled to the coupling cavity from which the stopper is separated.

Systems and methods for pumping milk from a breast responsive to a controller, 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.

A breast milk collection and storage system is disclosed that comprises a manual breast pump. The manual breast pump comprises a breast cup configured to engage with a mother's breast. The breast cup comprises an opening. The manual breast pump also comprises a reservoir at a base of the breast cup configured to receive breast milk through the opening and collect breast milk extracted from the mother's breast. The breast milk collection and storage system also comprises a stopper configured to seal the opening to prevent leakage of breast milk from the reservoir. The breast milk collection and storage system further comprises a capsule configured to enclose the manual breast pump with the stopper and apply a compression force to the stopper to maintain the seal of the opening when the capsule is closed.

A system for synchronizing one or more breast-pumping sessions of an individual (such as a mother) and milk consumption by a second individual (such as a baby or infant) is described. In particular, based on measurements of a volume of the collected milk as a function of time and received information specifying milk consumption by the second individual as a function of time, a control circuit may determine a need for milk. Then, the control circuit may provide feedback based on the determined need for milk that synchronizes the one or more breast-pumping sessions and the milk consumption. For example, the feedback may alert the individual to initiate a breast-pumping session and/or may provide a signal to a breast pump that initiates a breast-pumping session.

Systems and methods for pumping milk from a breast responsive to a controller, 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.

This disclosure generally relates to a smart breast pump system that includes at least one sensor to monitor the expression of breast milk. The smart breast pump system may further include a mobile device which wirelessly receives sensor data from the at least one sensor. Additionally, the smart breast pump system may further include at least one server device, which wirelessly receives sensor data from the at least one mobile device.

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 breastmilk collection device includes breast contacting flange, a vacuum reservoir, flexible diaphragm separating the breast contacting flange and the vacuum reservoir, and a flange receiver between the breast contacting flange and the flexible diaphragm. The breast contacting flange has a wide portion for accepting the breast and a narrow portion. The flexible diaphragm is located between the narrow portion and the vacuum reservoir. The flexible diaphragm moves between a sealed configuration, in which the breast contacting flange is sealed off from the vacuum reservoir, and an open valve configuration, in which the flexible diaphragm acts as a one-way valve to allow expressed milk to flow through a milk flow opening between the flexible diaphragm and the breast contacting flange when an opening pressure is reached in the breast contacting flange.
