- 2 Phase Expression Selection Button: Toggles between Stimulation and Expression modes.
- Buttons for Suction Strength (+/-): Adjusts the suction level.
Pumping Modes
The pump operates in two distinct phases to mimic a baby's natural feeding pattern:
- Stimulation Phase: This mode uses rapid, gentle suction to stimulate milk let-down. It typically lasts for the first 2-3 minutes of a pumping session.
- Expression Phase: Once milk let-down occurs, switch to this mode. It uses slower, deeper suction to efficiently express milk.
Adjusting Suction and Speed
The pump offers 9 levels of speed and suction adjustment. Use the '+' and '-' buttons on the control panel to increase or decrease the intensity to your comfort level. It is recommended to start with a lower setting and gradually increase until you find a comfortable and effective suction level.
Pumping Technique
Ensure the breast shield is centered over your nipple and forms a complete seal with your breast. Begin with the Stimulation Phase. Once milk begins to flow, switch to the Expression Phase. Pump until your breast feels empty or milk flow significantly slows. The unique 3D pumping technology with a soft silicone flange is designed to imitate a baby's natural sucking action for comfortable and effective milk removal.
Cleaning and Maintenance
Proper cleaning and maintenance are essential for hygiene and optimal pump performance.
After Each Use
- Disassemble all parts that come into contact with breast milk (breast shield, valve, bottle, tubing connectors, silicone cushion).
- Wash these parts thoroughly with warm soapy water. Use a dedicated brush for cleaning pump parts.
- Rinse all parts with clean water.
- Sterilize parts by boiling them in water for 5 minutes, using a steam sterilizer, or following manufacturer's instructions for other sterilization methods.
- Allow all parts to air dry completely on a clean surface or drying rack before reassembling or storing.
Main Pump Unit
The main pump unit and tubing do not come into contact with breast milk. Wipe the main pump unit with a clean, damp cloth. Do not immerse the main pump unit in water or other liquids.
Storage
Store all clean and dry pump components in a clean, dry place when not in use.
