1. A method of using a breast pump system to express breast milk from a user'"'"'s breast, wherein the breast pump system comprises a suction tubing, a milk tubing, a pump, a vent valve, a suction and milk separator device, a milk bottle, an isolation valve and a breast shield;

  • wherein the suction tubing has a first and second end;

    wherein the milk tubing has a first and second end;

    wherein the first end of the suction tubing and the first end of the milk tubing are fluidly connected to the pump;

    wherein the second end of the suction tubing and the second end of the milk tubing are fluidly connected to the suction and milk separator device;

    wherein the breast shield is fluidly connected to the suction and milk separator device;

    wherein the suction and milk separator device has a check valve positioned at the connection to the milk tubing;

    wherein the check valve has an open and a closed position and the check valve is in the closed position when the suction on the suction and milk separator device is greater than the suction on the milk tubing;

    wherein the vent valve is fluidly connected to the suction tubing and is positioned between the pump and the suction and milk separator device;

    wherein the vent valve is fluidly connected to a vent to atmosphere;

    wherein the milk bottle is fluidly connected on the milk tubing between the suction and milk separator device and the isolation valve; and

    wherein the isolation valve is fluidly connected on the milk tubing between the milk bottle and the pump;

    the method comprising attaching the breast shield to a breast of a lactating person, and running the breast pump system in a cycle comprising a pumping step and a venting step;

    wherein the pumping step comprises the pump pumping;

    the vent valve closed such that the suction tubing is disconnected from the vent and connected to the pump;

    the pressure at the breast shield is reduced and the user'"'"'s breast is drawn into the breast shield;

    the check valve is closed;

    milk is expressed from the user'"'"'s breast and collected in the breast shield;

    wherein during the cycle the isolation valve opens for a about less than 0.5 second such that the pump is connected to the milk bottle;

    the pressure in the milk bottle and the milk tubing drops;

    wherein the vent step comprises the vent valve open such that the suction tubing is connected to the vent and disconnected from the pump;

    the pressure in the suction tubing and the suction and milk separator device rises to that of about atmospheric pressure;

    the check valve opens;

    expressed milk is pulled through the breast shield, the suction and milk separator device, and the milk tubing to the milk bottle;

    wherein the cycle takes about less than 5 seconds, andwherein the pumping step, and the vent step cycles repeat until milk expression is complete.
