A vacuum control system controls the amount of time that pressure is applied to a breast and the amount of time no pressure is applied to the breast, independent of the vacuum level. The amount of time that pressure is applied to a breast and the amount of vacuum applied to the breast cups can be varied by the user. A disposable biological filter isolates the pump from the breast cups. The biological filter is packaged in a housing that has an O-ring push-in connector to connect the collection system to the pump. The vacuum applied to the breast cups is monitored. The control system maintains the vacuum at a level set by the user. A second higher level is used as a safety threshold. The control system shuts down the pump when this higher level is sensed. The breast cup is constructed to provide a controlled collapse when vacuum is applied to mimic the suckling of an infant.

A programmable electric breast pump system includes a vacuum pump pneumatically coupled to breast cups and a vacuum relief valve bypassing the vacuum pump. A controller receives command input from a vacuum level selector and a vacuum rate selector, and feedback from a pressure sensor measuring vacuum in the breast cups. In response, the controller cycles the relief valve between minimum and maximum vacuum setpoints to create a periodic vacuum pulse in the breast cups. By adjusting the vacuum min / max levels and vacuum rate, a user may change the strength of the pulse after let-down, or synchronize the frequency of the pulse with the natural refractory time of a lactating breast. Related methods for operating a breast pump mimic the suckling cycle of a nursing infant and may include steps for bypassing a vacuum pump with a vacuum relief valve, selecting a vacuum rate and a vacuum level, driving a vacuum pump at the selected vacuum rate, cycling the relief valve according to the vacuum level, and adjusting the vacuum level until the vacuum pulses in phase with a natural refractory time.

An electric breast pump is disclosed as including a hood to be fitted over a breast of a user, a chamber in fluid communication with the hood member via a one-way valve, a pump motor operatively associated with a pump diaphragm movable to draw air from the hood into the chamber via the valve, in which the chamber has an opening and a lid which is operatively associated with the motor, in which the lid is movable between a first position to close the opening and a second position in which the opening is open, and in which the lid is at the first position when the motor is in operation and is at the second position when the motor is not in operation. The breast pump also includes sensors for detecting the passing of milk, and a microcontroller for calculating the rate of flow of milk on the basis of data received from the sensors.

A breast pump comprises a breast cup and a source of positive and vacuum to the breast cup. The pressure and vacuum are set to an initial value for a fixed period of time, and they are not adjusted by a user. The initial values are selected to allow the breast cup to be repositioned by a user before higher levels of pressure and vacuum are applied.

A breast milk pump having an electric motor, a pump driven by the motor, a suction cup, an electrically activated first three-way valve in a suction line, an electrically activated second three-way valve in a pressure line, an electronic control system, which sets the electric motor into an operating mode or an idle mode depending on an activation of a switch; in the operating mode, it operates the electric motor and the electrically activated first and second three-way valves in cycles, which comprise a suction phase, in which the electric motor is switched on, the inlet of the pump is connected to the suction cup via the first three-way valve and a floater valve, the pump outlet is connected via the second three-way valve.

The invention relates to an electric control breast pump, which aims to solve the disadvantages that a proximate manual or electric breast pump is inconvenient to operate, the uniformity and the stability for milk pumping are bad, a membrane is not durable, air can enter the milk to cause excessive bubbles in the milk, and the quality of the milk is influenced. The key points of the technical scheme are as follows: the electric control breast pump comprises a milk bottle and a breast pump main body, wherein, the breast pump main body comprises a bottle cover seat, a milk pumping part, a milk receiving valve and a negative pressure generating part; the milk pumping part and the negative pressure generating part are arranged at the top of the bottle cover seat; the milk receiving valve is arranged at the bottom of the bottle cover seat; the milk pumping part and a negative pressure cavity of the negative pressure generating part are communicated with a valve cavity of the milk receiving valve; in addition, the electric control breast pump is characterized in that the negative pressure generating part comprises a negative pressure cavity seat, a soft bowl-shaped membrane, a cavity seat cap and an electric air suction device, the bowl-shaped membrane is positioned in the negative pressure cavity of the negative pressure cavity seat and is arranged on a negative pressure cavity opening through a bowl opening, the cavity seat cap is tightly connected with the negative pressure cavity opening of the negative pressure cavity seat and can mutually compress the bowl opening of the bowl-shaped membrane and the negative pressure cavity opening, and an inner concave air cavity of the bowl-shaped membrane is communicated with the electric air suction device through an air hole formed on the cavity seat cap.
