A breast pump includes a housing including a first side and a second side. The first side and the second side define a cavity therebetween. The second side includes a concave surface defining a recess. The breast pump also includes a breast cup for engaging at least a portion of a breast including a nipple and an area surrounding the nipple. The breast cup is attached to the second side of the housing and positioned at least partly within the recess defined by the concave surface. The breast pump further includes a vacuum pump assembly, a container, a heater mounted to the housing, and a power source. The heater extends along the concave surface of the second side of the housing in thermal connection with the breast cup. The heater is configured to provide heat to the breast cup when the power source provides electrical current to the heater.

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 collecting method by stimulating the mammary gland of a breastfeeder to eject breast milk includes providing an audio-playing device to generate an auditory stimulation, providing a video-playing device to generate a visual stimulation, and providing a breast pump to generate a tactile stimulation and collect the breast milk. In this method, the breast pump is placed on a breast of the breastfeeder, and one or more deformable members of the breast bump is inflated or deflated alternately to touch and press the breast so as to mimic a breastfeeding condition to generate the tactile stimulation, so that the pituitary gland of the breastfeeder can be directly stimulated by the multiple sensory stimulations to secret prolatine or oxytocin, thereby allowing the mammary gland of the breastfeeder to eject the breast milk to be collected by the breast pump and treated collectively.

A breast pump device is disclosed. The breast pump device includes a primary machine portion, and a secondary control portion provided separately from the primary machine portion. The primary machine portion further includes a main housing, a pump attached to the main housing and configured to generate a pressure to cause breast milk to be expressed by a user of the breast pump device, and a milk container coupled to the pump and configured to accommodate the breast milk. The secondary control portion is electrically coupled to the primary machine portion without an airway and configured to remotely operate the primary machine portion.

A filter system comprising a filter cartridge and a filter insert, wherein the filter cartridge has an internal main suction path and an internal bottle suction path. Positioned on the internal main suction path is an internal main suction path vent hole, and positioned on the internal bottle suction path is an internal bottle suction vent hole. Positioned between the internal bottle suction path and the internal bottle suction vent hole is an internal bottle suction path filter element, wherein the filter insert is configured to engage sealingly, moveably and releasably with the filter cartridge. The filter insert has two suction ports that align with the internal main suction path vent hole and the internal bottle suction vent hole when engaged with the filter cartridge.

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 wearable breast pump system is provided. The wearable breast pump system can include a housing having a pump, a breast flange, and a milk container. The pump can form part of a closed loop system that drives a separate, deformable diaphragm to generate negative air pressure. The diaphragm can be removably mounted on a breast shield.

An in-bra wearable milk collection device for use in a breast pump system. The milk collection device comprises a breast shield, a shell, and a diaphragm. The breast shield includes a nipple tunnel and breast flange. The diaphragm has a dry side for connection to an air pump and a wet side configured to contact milk. The breast shield is removably attachable to the shell and, when attached, the breast shield and shell form a milk container. The breast shield is made from a deformable material such that the breast shield is configured to deform to attach to the shell.

A breast pump device is disclosed. The breast pump device includes a primary machine portion, and a secondary control portion without any pump. The secondary control portion is provided separately from the primary machine portion. The primary machine portion further includes a main housing, a pump attached to the main housing and configured to generate a pressure to cause breast milk to be expressed by a user of the breast pump device, and a milk container coupled to the pump and configured to accommodate the breast milk. The secondary control portion is electrically coupled to the primary machine portion and configured to remotely operate the primary machine portion. The primary machine portion is configured to be worn on a breast of the user during operation. The secondary control portion is integrated into a wearable device configured to be worn on the neck or head of the user.

A wearable lactation aid apparatus and system with a controller that operates to express breast milk from a lactating user using compression pressure and draw the expressed breast milk from a reservoir into a collection container with suction. The apparatus includes a compression device positioned on a breast of the user. The compression device is configured to repeatedly apply and release compression on the breast. A nipple cone is positioned on the breast of the user and is connected to a shield. A pump connected to the shield and in fluid communication with a collection container positioned between the pump and the shield creates a vacuum in the collection container to draw in the expressed milk.
