4. Product Components
Familiarize yourself with the various parts of your Dr.isla EB11 breast pump:
- Main Pump Unit: Houses the motor, battery, and control panel.
- Silicone Breast Flange: The part that comes into contact with the breast, designed for comfort and efficient suction.
- Connector: Connects the flange to the milk collection bottle and the main pump unit.
- Milk Collection Bottle: Collects expressed milk.
- Duckbill Valve: A one-way valve that ensures milk flows into the bottle and prevents backflow.
- Silicone Diaphragm: Creates a closed system for hygienic pumping and prevents milk from entering the tubing/motor.

This image illustrates the ergonomic design of the breast flange, featuring a 106-degree wide angle to ensure a comfortable and secure fit, which helps in reducing compression and promoting efficient milk flow.

This diagram details the advanced anti-reflux system, which includes a gas-liquid separation silicone membrane and a one-way flow duckbill valve. This design prevents milk backflow into the pump unit, ensuring hygiene and protecting the device.
5. Assembly and First Use
5.1. Assembly
- Ensure all parts are clean and sterilized before assembly (refer to Section 7).
- Insert the duckbill valve firmly into the bottom of the connector.
- Place the silicone diaphragm onto the top of the connector, ensuring a tight seal.
- Screw the milk collection bottle onto the bottom of the connector.
- Attach the silicone breast flange to the connector.
- Finally, connect the assembled breast pump unit to the main pump unit, ensuring it clicks securely into place.
5.2. Charging
Before first use, fully charge the breast pump. Connect the USB charging cable to the main pump unit and plug the other end into a suitable USB power source (e.g., wall adapter, power bank). The LED display will indicate charging status. A full charge typically takes a few hours.
6. Operating Instructions
The Dr.isla EB11 features an intuitive control panel with an LED display and easy-to-use buttons.

This image highlights the intuitive control panel of the Dr.isla EB11, featuring an LED display for time and settings, and buttons for power, mode selection, and adjusting the 9 suction levels. It also illustrates the three distinct operating modes: Massage, Expression, and Blend (Hybrid).
6.1. Power On/Off
- Press and hold the Power button (usually indicated by a circle icon) to turn the pump ON or OFF.
- The LED display will light up, showing the current mode, suction level, and pumping time.
6.2. Selecting Modes
The Dr.isla EB11 offers three distinct pumping modes:
- Massage Mode (M): Designed to stimulate milk let-down with gentle, rapid suction. Use this mode for 2-5 minutes at the beginning of each pumping session. It has 9 adjustable levels.
- Expression Mode (+): Provides a slower, stronger suction to efficiently express milk once let-down has occurred. It has 9 adjustable levels.
- Hybrid Mode (Blend): Combines elements of both massage and expression for a personalized and comfortable experience. It also has 9 adjustable levels.
Press the Mode button (often labeled 'M' or a wave icon) to cycle through the available modes.
6.3. Adjusting Suction Levels
Each mode has 9 adjustable suction levels. Use the '+' and '-' buttons on the control panel to increase or decrease the suction intensity to your comfort level. Start with a lower level and gradually increase until you find a comfortable yet effective setting.
6.4. Pumping Session
A typical pumping session lasts 15-20 minutes per breast. The pump may have an automatic shut-off feature after a set duration. Monitor the milk flow and adjust settings as needed.
7. Cleaning and Sterilization
Proper cleaning and sterilization are crucial for maintaining hygiene and the longevity of your breast pump. All parts that come into contact with breast milk are dishwasher-safe.
