An in-bra wearable breast pump is provided. The breast pump includes an air pump system for generating a base level vacuum and a pumping vacuum, a breast shield for receiving a user's breast and having a first side and a second side, a first channel for drawing the base level vacuum on the first side of the breast shield, and a second channel for drawing the pumping vacuum on the second side of the breast shield.

Breast pump

A breast pump system comprises at least one wearable milk collection hub connected via an air line to a combined external air pump and control unit. Each milk collection hub comprises: (a) a breast shield made up of a breast flange and a nipple tunnel; (b) a flexible diaphragm that is configured to prevent milk from reaching the external air pump; (c) an outer shell that is configured to removably attach to the breast shield, such that, when attached, the breast shield and outer shell form a vessel for collecting milk; and (d) a diaphragm cap that is configured to be secured over the diaphragm, forms part of the front face of the outer shell, and includes a port connected to the air line.

Wearable breast pump system

There is provided a method of measuring liquid volume in a sealed container of a breast pump of known volume comprising liquid and gas. The method includes a measurement phase, measuring the volume of gas in the container by changing a first parameter of the gas by a known amount. The method also includes measuring a change in a second parameter of the gas; calculating the volume of gas in the container using the measured change and a predetermined operation equation; and determining the volume of liquid in the container based on the calculation.
