Systems and methods for pumping milk from a breast, 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 one approach, the breast pump assembly includes a breast adapter and a receptacle configured to cup the breast adapter, and the breast adapter is removable from the receptacle.

A breast milk collection device includes a reservoir volume and an adaptor having one end to receive a woman's breast. The adaptor has a drip tube communicating with the reservoir. A source of cyclical application and relief of vacuum force is applied to the woman's breast located in the adaptor for the expression of breast milk. A one-way assembly permits breast milk to enter the reservoir and to submerge the valve element. The valve assembly includes a flexible barrier having an interior hollow chamber in fluid communication with said cyclical source of vacuum force and relief pressure, the flexible barrier fluidly isolating the source from the reservoir. The flexible barrier inflatably expands when relief pressure is applied to the interior of the flexible barrier, the flexible barrier becoming deflated when a vacuum force is applied to the hollow interior of the flexible barrier.

A method for operating a breastpump unit for expression of human breastmilk and various breast shields for use in this method allow a maximum pumping performance and a minimum pumping duration per pumping session. The breast shield has an inner chamber for receiving a nipple of the breast and also at least one outer chamber which at least partially surrounds the nipple. The inner chamber is subjected to a constant pressure and the at least one outer chamber is subjected to a pulsating pressure.

An integrated breast pump includes a housing, a triple valve integrated with the housing, a breast adapter, a negative pressure generation device, a negative pressure transmission element and an one-way valve. The triple valve includes a liquid inlet, a liquid outlet and a negative pressure port. The breast adapter includes a liquid guiding outlet and is detachably connected with housing. The liquid guiding outlet communicates with the liquid inlet. The negative pressure generation device includes a pumping port and is configured for providing negative pressure periodically. The negative pressure generation device is detachably connected with housing, and the pumping port is disposed towards the negative pressure port. The negative pressure transmission element is disposed in the negative pressure port and communicates with the pumping port. The negative pressure transmission element is configured for generating deformation periodically according to the negative pressure. The one-way valve is connected with the liquid outlet.

The present disclosure discloses an assembling-facilitated breast pump, including, a main body, a milk flowing member and a breast cover; the main body includes a suction assembly and a milk storage container; the suction assembly is detachably connected to the milk storage container a negative pressure tank is arranged in the milk storage container; the suction assembly is communicated to the negative pressure tank; the entire main body is hemispherical; the milk flowing member is hermetically plugged, into the negative pressure tank; one end of the milk flowing member is provided with an opening; a side of the milk flowing member close to the opening is provided with a milk outlet; the milk outlet is used for being communicated to an accommodating cavity of the milk storage container; and a narrow end of the breast cover is hermetically plugged to the opening.

A breast pump includes a main body and a breast milk suctioning shield. The main body has an accommodation space. The breast milk suctioning shield is assembled in the accommodation space and detachably connected to the main body. A front end of the breast milk suctioning shield has a breast shielding portion, and a nipple passage extends from a rear end of a center portion of the breast shielding portion. One or more deformable members are assembled with an annular connection portion between the breast shielding portion and the nipple passage, and the deformable member is controlled to be inflated or deflated by a first air pump.

The breast milk suctioning shield is assembled in an accommodation space of the main body and detachably connected to the main body. A front end of the breast milk suctioning shield has a breast shielding portion, and a nipple passage extends from a rear end of a center portion of the breast shielding portion. One or more deformable members and a non-deformable supporting member are assembled with an annular connection portion located between the breast shielding portion and the nipple passage. The air pump has an intake port and an exhaust port. The intake port is controlled by a first valve controller to suction the nipple passage and generate a negative pressure, and the exhaust port is controlled by a second valve controller to inflate or deflate the deformable member.

A breast pumping assembly is provided. The assembly allows for a breast pumping mother to be optimally positioned and comfortable while pumping breast milk, leading to quicker and more effective pumping. The breast pumping assembly is adjustable to adapt for different sized mothers and changing body size and shape as pumping progresses.

Systems and methods for pumping milk from a breast, wherein the milk is expressed from the breast under suction and milk is expulsed from the pumping mechanism to a collection container assembly.

A passive milk collection device for storing milk comprises a flexible inner member including a nipple hole for receiving a nipple, and in which, in use, part of the rear surface of the inner member is configured to securely seal onto a user's breast. The device includes a removable rigid outer member configured to attach onto the front surface of the inner member and to provide a free air space around the nipple area for storing milk from the nipple. The circumference of the outer edge of the rear surface of the flexible inner member is substantially larger than the circumference of the rigid outer member.
