The description details basic electronic controls and pre-programmed modes, with no mention of adaptive learning, data analysis for personalized operation, or any terms associated with AI/ML. The software is described as "embedded firmware" controlling fixed modes and suction levels.
No.
The device is intended to express milk from lactating women, which is a collection or assistive function, not a therapeutic treatment for a medical condition.
No
The device is a breast pump, intended to express and collect milk. It does not perform any diagnostic function such as identifying a disease or condition.
No
The device description explicitly details hardware components such as a pump motor, milk collection parts, adjustment buckle, charging cable, buttons, and an LED display. It also mentions being electrically powered by an internal rechargeable battery. While it uses embedded firmware (software), it is clearly a physical device with significant hardware components.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. They are used outside of the body (in vitro) to diagnose, monitor, or screen for diseases or conditions.
- Device Function: The Wearable Breast Pump, Model S18 is designed to collect milk from a lactating woman's breast. It does not analyze or test the milk or any other bodily fluid to provide diagnostic information.
- Intended Use: The intended use is clearly stated as "to express milk from lactating women in order to collect milk from their breasts." This is a mechanical function, not a diagnostic one.
The device is a medical device, but it falls under a different category than IVDs. It's a device used for a physiological process (milk expression).

Device Description
The Wearable Breast Pump, Model S18 is an electrically powered breast pump to be used in home environment by a single user. The device is provided non-sterile and can be re-used by a single user. The device is electrically powered by an internal rechargeable Li-ion battery. It can be charged using 5V DC adaptor and the device is designed to be not used during charging.
The device consists of the pump motor, milk collection parts, adjustment buckle and charging cable. The device functionality is controlled using an embedded firmware. The subject device has three modes of operation - Expression mode, Stimulation mode and Massage mode, and each mode of operation allows for switching between nine suction levels.
The device has three buttons, a power button to turn the device on/off or switch between the modes, a '+ plus' button to increase the suction level and a '- minus' to decrease the suction level within a mode. The device includes an LED status display for the device operating mode and battery status indicator on the pump body. The operating mode LED changes to specific color based on the mode of operation. The device is designed to automatically shut down after 30 minutes of continuous operation.
The device operates on a suction(vacuum) cycle that consists of an inhale (letting in air to release vacuum) and an exhaust (removal of air to create vacuum) process. When the breast pump is powered on, the vacuum pump exhausts the air inside the cavity. Once the suction strength reaches the set value, the vacuum pump stops and the valve for the milk opens and expressed milk flows into the bottle due to a pressure difference.
