A hands-free breast pump comprises a funnel-shaped adsorption unit having an adsorption surface and a suction tank; a suction chamber having an extension part, the extension part having a connection pipe and a second suction hole formed on the lower portion of the inner peripheral surface, and a first coupling part extended downwardly from the extension part and having a third suction hole formed on the lower portion of the inner peripheral surface thereof; and a storage vessel coupled to the first coupling part in the horizontal direction with the adsorption surface to store the breast milk discharged from the backflow prevention unit therein.

A breast milk pump includes a breast interface member which has an inner cavity through which milk can flow, and a negative pressure assembly in fluid communication with one side of a diaphragm. An opposite side of the diaphragm is in fluid communication with the inner cavity. The diaphragm separates the inner cavity from the negative pressure assembly. A suckling assembly includes a tongue member and an actuator coupled to the tongue member for causing movement of the tongue member. A tongue position adjustment assembly is coupled to the suckling assembly and operative to cause displacement of the suckling assembly with respect to an inner surface of the inner cavity.

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.

Systems and methods with variable and customized functionality for pumping milk from a breast and calculating or determining volumes pumped, 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 a pump arrangement (6) for use with a double breast pump device, a first air conduit (65) and a second air conduit (66) have a function in connecting respective expression kits (2, 3) to the pump arrangement (6). Each of the air conduits (65, 66) N is connectable to and disconnectable from a suction side and a discharge side, respectively, of a pump (61) that is included in the pump arrangement (6). Further, the air conduits (65, 66) are connectable to and disconnectable from each other directly through an intermediate switching mechanism (70) arranged between the air conduits (65, 66) at a bypass position with respect to the pump (61), so that it is possible to directly transfer vacuum between the air conduits (65, 66) and to thereby support the functioning of the pump (61) which may be relatively small for that reason.

A system and method for increasing the efficiency of a breast pump device is disclosed. The system includes a breast pump device with a vacuum pump to provide suction force to a flange attached to the breast of a user. The device includes a controller that controls the pump with different modes of pumping operation including a prime mode and a pump mode. The pump device may include a pressure sensor that provides data to a transceiver sending data to an external device. The flange unit may include a substantially circular rim with a layer configured to contact the skin of a user to convey the suction force. The system may include milk containers that include a machine scannable external identification tag.

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 system for hands-free nursing and breast pumping includes a breast compression device with a plurality of thermoformed fluid bladders designed to fit adjustably against each breast and inflate and deflate with minimal power requirements. The compression device and its controller fit inside of a nursing garment designed to receive the device and controller for optimal compression. The nursing garment and the compression device have openings over the nipples so that a breast pump flange can be inserted through them and used in a typical manner for the extraction of breast milk, thus increasing the amount of milk expressed.

Disclosed herein is a breast pump. The breast pump includes a milk capture system that includes a cupped flange. The cupped flange includes a nipple recess for receiving a nipple. The breast pump further includes a manifold which may be removably connected to the cupped flange. The manifold includes a nipple cavity in which vacuum suction is applied to a nipple. The manifold further includes a spout that drains milk away from the vacuum suction. The breast pump further includes a milk collection system which is removably connected to the manifold. The milk collection system includes a milk receptacle for containing milk expressed from a breast. Further disclosed is a breast pump system which includes a milk capture system, a manifold, and a milk collection system.

A method for facilitating milk extraction from a female breast may involve applying a breast contacting portion of a breast pump system to a breast, activating the breast pump system to administer multiple breast pumping cycles, and applying vibrations to the breast during at least a portion of each of the breast pumping cycles, using a vibration device. A vibration generating device may be a component of a breast pump system, an added attachment on a breast pump system or a separate component that works in conjunction with a breast pump system.
