5. Bedienungsanleitung
The Medela Harmony Manual Breast Pump features two distinct pumping phases to mimic a baby's natural feeding rhythm: a stimulation phase and an expression phase.
Pumpvorgang:
- Positionierung: Center your nipple in the PersonalFit Flex Breast Shield tunnel. Ensure a comfortable seal around your breast.
- Stimulationsphase: Begin by pressing the smaller, upper part of the handle (the stimulation lever) quickly and lightly. This rapid, shallow suction helps stimulate milk let-down. Continue for approximately 2 minutes or until milk begins to flow.
- Ausdrucksphase: Once milk starts flowing, switch to the longer, lower part of the handle (the expression lever). Press this lever fully and hold for a few seconds, then release. This creates a slower, deeper suction to efficiently express milk. Adjust the rhythm and suction strength to your comfort and milk flow.
- Dauer: Pump until your breast feels soft and milk flow slows significantly. This typically takes 10-15 minutes per breast.
- Lagerung: After pumping, carefully remove the breast pump from your breast. Unscrew the bottle from the connector and seal it with the provided lid for storage.

6. Reinigung und Wartung
Proper cleaning and maintenance are crucial for hygiene and the longevity of your breast pump. All parts that come into contact with breast milk should be cleaned after each use and sterilized daily.
Nach jedem Gebrauch:
- Alle Teile, die mit Muttermilch in Berührung kommen (Brusthütchen, Konnektor, Ventil, Membran, Flasche), müssen demontiert werden.
- Rinse all separated parts with cold water to remove milk residue.
- Wash parts in warm, soapy water using a mild dish soap. Use a clean brush dedicated for pump parts.
- Mit klarem Wasser gründlich abspülen.
- Air dry on a clean paper towel or drying rack. Avoid using a cloth towel as it may leave lint.
Daily Sterilization:
In addition to washing, sterilize all milk-contacting parts once a day:
- Kochen: Place disassembled parts in a pot of boiling water for 5 minutes. Ensure parts do not touch the bottom of the pot to prevent damage.
- Spülmaschine: All components are dishwasher safe. Place parts on the top rack of your dishwasher.
- Dampfsterilisation: Use a microwave steam sterilizer bag or unit according to its instructions.
Um Bakterienwachstum zu verhindern, muss sichergestellt werden, dass alle Teile vor dem Zusammenbau oder der Lagerung vollständig trocken sind.
