3. Product Components

The eSynic Wearable Electric Breast Pump consists of several key components:

• Motor Unit: The main control unit with LED display and buttons.
• Breast Flange: The part that comes into contact with the breast. Includes 24mm, 21mm, and 19mm sizes.
• Milk Collector Cup: 210ml capacity for collecting expressed milk.
• Silicone Diaphragm: Creates a closed system for hygienic pumping.
• Valve: Controls milk flow into the collector cup.
• USB Type-C Charging Cable: For recharging the internal battery.

4. Setup and Assembly

4.1 First Use and Cleaning

Before using the breast pump for the first time, and after each subsequent use, all parts that come into contact with breast milk (flange, milk collector cup, silicone diaphragm, valve) must be cleaned and sterilized.

1. Disassemble all parts of the pump.
2. Wash all disassembled parts (except the motor unit) in warm soapy water. Use a soft brush for thorough cleaning.
3. Rinse thoroughly with clean water.
4. Sterilize the parts by boiling them in water for 5 minutes or using a steam sterilizer.
5. Allow all parts to air dry completely on a clean surface or use a clean cloth.
6. Wipe the motor unit with a damp cloth. Do not submerge.

4.2 Assembly

Assemble the pump as follows:

1. Insert the valve firmly into the bottom of the milk collector cup.
2. Place the silicone diaphragm onto the top of the milk collector cup, ensuring a tight seal.
3. Attach the breast flange to the milk collector cup, making sure it clicks securely into place. Choose the appropriate flange size (24mm, 21mm, or 19mm) for your comfort and milk flow.
4. Align the motor unit with the assembled milk collector cup and press down firmly until it is securely attached. The upgraded design allows for easy attachment without precise alignment.

4.3 Charging the Battery

The pump is equipped with a 1200mAh rechargeable lithium battery.

• Before first use, fully charge the pump for approximately 2.5 hours.
• Connect the USB Type-C charging cable to the charging port on the motor unit and plug the other end into a compatible USB power adapter (DC5V1A recommended).
• The LED display will indicate charging status. When the power indicator turns red, the battery is low and requires charging.
• A full charge provides approximately 150 minutes of operation, or 6-8 pumping sessions of 20 minutes each.

5. Operating Instructions

5.1 Wearing the Pump

Once assembled and charged, position the breast pump correctly:

• Place the assembled pump directly onto your breast, ensuring your nipple is centered in the flange tunnel.
• Ensure a good seal between the flange and your skin to prevent air leakage and maintain suction.
• Wear the pump inside your nursing bra for hands-free operation. The lightweight design (260g) ensures comfort.

5.2 Power On/Off and Mode Selection

• Power On: Press and hold the power button on the motor unit. The LED display will light up.
• Mode Selection: The pump features 4 modes:
  • Massage Mode: Gentle, rapid suction to stimulate milk let-down.
  • Expression Mode: Slower, stronger suction for efficient milk expression.
  • Auto Mode: Cycles through massage and expression patterns.
  • Lactation Mode: (Details not explicitly provided, but typically a combination or specific pattern for milk flow).
  Press the mode button to cycle through the available modes. The current mode will be displayed on the LED screen.
• Adjusting Suction Level: Each mode has 12 adjustable suction levels. Use the '+' and '-' buttons on the motor unit to increase or decrease the suction intensity to your comfort level.
• Automatic Shut-off: The pump will automatically shut off after 20 minutes of continuous operation.
• Power Off: Press and hold the power button to turn off the pump manually.

5.3 After Pumping

• Carefully remove the pump from your breast.
• Separate the motor unit from the milk collector cup.
• Pour the expressed milk into a suitable storage container. The anti-overflow design helps prevent spills during this process.
• Disassemble all parts that came into contact with milk and clean them according to the "Cleaning & Maintenance" section.

6. Cleaning and Maintenance

Proper cleaning and maintenance are crucial for hygiene and the longevity of your breast pump.

• After Each Use: Disassemble and clean all parts that come into contact with breast milk (flange, milk collector cup, silicone diaphragm, valve) as described in Section 4.1.
• Motor Unit: Wipe the exterior of the motor unit with a clean, damp cloth. Do not submerge it in water or sterilize it.
• Storage: Store all clean and dry components in a clean, dry place away from direct sunlight and extreme temperatures.
