PROBLEM TO BE SOLVED: To provide a portable, self-powered, energy-efficient, wearable milking pump system without discomfort, which includes a chest contact structure and a storage container and a structure for feeding breast milk from the chest to the storage container. A milking pump system 100 responds to pressure changes in the tubing caused by the entry of breast milk into the tubing 32, and compression elements 36, 38 are driven by dedicated compression drivers 44, 46. A pressure sensor 54 is used to provide feedback to the control device 52 for controlling the pressure feeding cycle to achieve and / or maintain the desired vacuum level. Breast milk is squeezed from the breast 2 under suction force and discharged from the pumping mechanism to the breast milk collection container 60 under positive pressure.
