The summary describes a standard electrically powered breast pump with user-controlled settings and embedded software, but there is no mention of AI or ML capabilities for adapting to the user or optimizing performance.
No
The device is intended to express and collect milk from lactating women, which is an assistive function rather than a therapeutic one. It does not treat or prevent any medical condition.
No
The device is a breast pump, intended for collecting milk, not for diagnosing any medical condition.
No
The device description explicitly lists multiple hardware components (flange, linker, silicone diaphragm, pump motor, USB cable, valve, milk collector, bra adjustment buckle, motor unit, LED display, rechargeable battery) and describes their physical function in expressing milk. While it mentions embedded software, the device is fundamentally a physical breast pump with integrated software for control.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "express milk from lactating women in order to collect milk from their breasts." This is a physical process of extracting a bodily fluid, not a test performed on a sample of that fluid to diagnose a condition or provide information about a physiological state.
- Device Description: The description details a mechanical pump that creates suction to extract milk. It does not mention any components or processes related to analyzing or testing the milk itself.
- Performance Studies: The performance studies focus on the safety and functionality of the pump (biocompatibility, electrical safety, vacuum levels, backflow protection, battery life), not on the accuracy or reliability of any diagnostic test performed on a sample.
IVD devices are designed to perform tests in vitro (outside the body) on samples of bodily fluids or tissues to provide information for diagnosis, monitoring, or screening. This breast pump does not perform any such tests.

Device Description
The Wearable Breast Pump (Model S9), is an electrically powered wearable single breast pump consisting of the following key components: a flange, linker, silicone diaphragm, pump motor, USB cable, valve, milk collector, and bra adjustment buckle. It is designed to work in the user's bra and has a rechargeable battery so it can be used hands-free without any external power cords. The motor unit includes a press-button user interface, pump body, and LED display. Pumping can be performed on one breast (single pumping). The user interface allows the user to switch from stimulation to expression mode and control the vacuum levels within those modes. Both stimulation and expression mode consist of 5 vacuum levels. The S9 model is capable of providing vacuum levels from 40-105 mmHg with cycling rates from 75-109 cycles per minute in stimulation mode and vacuum levels from 40-245 mmHg with cycling rates from 28-85 cycles per minute in expression mode. The model S9 Wearable Breast Pump is charged with a 5 V DC adaptor and powered by an internal rechargeable lithium-ion polymer battery. The motor unit operates on embedded software updates by end-users are not supported. The subject device is for repeated use by a single user in a home environment. The device is provided not sterile.
The breast pump expresses by creating a seal around the nipple using the flange and applying and releasing suction to the nipple. The milk is collection container, which can be used for storage. To prevent milk from flowing into the vacuum system, a backflow protection membrane physically separates the milk-contacting pathway from the vacuum system.
All other components (i.e., motor unit) of the subject device are not in contact with the breast.
The motor unit operates on a rechargeable battery and does not function when charging. The rechargeable battery can be charged from the external USB adapter if the motor unit is not in operation.
The subject device components are made of the following materials:
- Motor unit: acrylonitrile-butadiene-styrene (ABS) plastic
- Flange, tube, valve, diaphragm: Silicone
- Linker, milk collection container: Polypropylene
All milk contacting components are compliant with 21 CFR 174-179.
