A self cycling breast pump including a nurser bottle and a suction assembly adapted to be situated on a breast of a human for delivering milk to the nurser bottle upon the application of a suction thereto. Further provided is an electric pump adapted to generate a vacuum at an inlet upon the activation thereof. The inlet of the electric pump is connected to the suction assembly. Also included is an electronic vent valve adapted to vent the vacuum created by the electric pump upon the activation thereof for releasing the vacuum. Associated therewith is vent control circuitry for determining a rate of activation of the electric vent valve thereby creating a cycling suction at the inlet of the electric pump. Vacuum control circuitry is provided for allowing the manual governing of the level vacuum generated by the electric pump means. This is accomplished by controlling the speed of a motor associated with the pump. |
