Abstract
Systems and methods for pumping milk from a breast, wherein the milk is expressed from the breast under suction and milk is expulsed from the pumping mechanism to a collection container under positive pressure.
Claims45
A wearable system to pump fluid from a breast, the system comprising:
- a skin contacting structure configured and dimensioned to form a seal with the breast;
- a conduit in fluid communication with the skin contacting structure;
- a strain gauge associated with the conduit to provide a conduit strain;
- a motor associated with the conduit, the motor having a motor position;
- and
- a controller in communication with the strain gauge and the motor;
- wherein fluid extracted from the breast flows into a collection assembly for storing the fluid pumped from the breast;
- wherein the controller employs machine learning to interpret the motor position and the conduit strain to control the motor to arrive at a predetermined targeted pressure level within the system.
