Method and apparatus for controling flow rates and patterns of human milk secretion by a breast pump

1. An apparatus for controlling flow rates and patterns of milk secretion comprising:

a breast pump comprising a linear source of vacuum; and

a control circuit comprising a controller for controlling the breast pump programmed to receive information on milk flow rates and patterns of a breastfeeding baby and to convert the information to corresponding voltage levels and patterns to be applied to the breast pump; and a nursing meter for determining and providing said information on flow rates and patterns.

2. The apparatus of claim 1 wherein said control circuit is located inside the breast pump.

3. The apparatus of claim 1 wherein said controller is arranged to control the operating voltage of the linear vacuum source, preprogrammed with a communication protocol allowing it to receive required operating voltage values and variation pattern, from a nursing meter, for achieving the required vacuum values and pattern;

and wherein the control circuit further comprises a digital-to-analog signal converter; and

a voltage booster to allow reaching the required voltage values.

4. The apparatus of claim 3 wherein said controller is preprogrammed with:

a communication protocol allowing it to receive, from the nursing meter, the required said vacuum values and pattern; and

data of the required said operating voltage values and variation pattern, to achieve the communicated vacuum values and pattern.

5. The apparatus of claim 3 wherein said controller is preprogrammed with:

a communication protocol allowing it to receive, from the nursing meter, the required flow values and pattern, of the milk to be secreted by using the pump; and

data of the required said operating voltage values and variation pattern, to achieve the communicated milk flow rate and pattern.

6. The apparatus according to claim 1 wherein said controller is programmed to perform said conversion based on a predetermined conversion table between vacuum power and pattern of a breast pump and flow rate and pattern.

7. A method for generating data to be stored in a controller of a control circuit of a breast pump comprising a linear source of vacuum, the method comprising:

receiving from a nursing meter information on milk flow rate and pattern of breastfeeding babies;

using the breast pump linear source of vacuum to generate flow through a tube at different vacuum powers and patterns;

measuring the flow rate and pattern through the tube generated by the pump,

creating a conversion table from flow rate and pattern through the tube to suction power and pattern of the pump.

8. The method according to claim 7

wherein the controller for controlling the breast pump is programmed to receive information on milk flow rates and patterns of a breastfeeding baby and to convert the information to corresponding voltage levels and patterns to be applied to the breast pump.

9. The method according to claim 8 wherein said control circuit is located inside said breast pump.

10. A method of controlling the flow rate and pattern of human milk secretion while using a breast pump, the method comprising:

using a nursing meter to measure flow rate and pattern generated by a suckling baby,

converting the measured flow rate and pattern generated by the suckling baby to a suction power and pattern, and

applying the suction power and pattern to the breast pump.

11. The method of claim 10 wherein converting the measured flow rate and pattern generated by the suckling baby is based on a predetermined conversion table.

12. The method of claim 10 further comprising creating the conversion table by:

using a breast pump to generate flow through a tube at different vacuum powers and patterns,

measuring the flow rate and pattern through the tube generated by the pump,

creating a conversion table from flow rate and pattern through the tube to suction power and pattern of the pump.
