Abstract: 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.

Abstract: A wearable passive suction-based milk collection device comprises a compressible milk pouch with a nipple hole or opening in a rear face of the compressible milk pouch. The rear face of the compressible milk pouch is configured to seal against at least part of the user's breast when the pouch is compressed by a user in order to create a negative air pressure inside the pouch, providing suction onto the nipple thereby drawing milk from the nipple for collection in the milk pouch. The device is shaped, at least in part, to fit inside a bra.

Abstract: 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.
