The electric breast pump (models FZ-P8, YH-P8, YH-P8X) is a wearable electric breast pump intended to express milk from lactating women in order to collect milk from their breasts. The device is intended for a single user.

Device Description

The electric breast pump (models FZ-P8, YH-P8, YH-P8X) is an electrical wearable breast pump powered by a rechargeable Li-ion battery. It consists of a Pump, Diaphragm, Cup, Valve, Silicone breast shield (flange) and dust cap:

The pump is the core component of the electric breast pump. It generates a cyclic negative pressure (vacuum) to simulate a baby's sucking motion, drawing milk from the breast into the collection system. The pump is electrically driven and controlled via a motor and control unit, typically offering adjustable suction levels and mode. The diaphragm separates the milk collection system from the pump mechanism, preventing breast milk from entering the pump motor and tubing. The cup is the container that collects and stores the expressed breast milk. The valve controls the one-way flow of breast milk. It opens and closes in sync with the suction cycles to allow milk to flow into the cup while preventing backflow. The silicone breast shield, also known as the flange, is the part that comes into direct contact with the breast. It creates a seal around the nipple and areola to enable effective suction. The dust cap covers the opening of the breast shield or milk collection port when the electric breast pump is not in use. It prevents dust, dirt, and other contaminants from entering the breast pump

The electric breast pump has 2 (Primary mode and secondary mode) x 3 modes (Massage Mode, Expression Mode, and Mixed Mode), each mode has 10 adjustable levels:

Massage Mode provides a vacuum range of 40–190 mmHg and a frequency of 52–110 cycles per minute;
Expression Mode provides a vacuum range of 80-280 mmHg and a frequency of 19–75 cycles per minute;
Mixed Mode provides a vacuum range of 80-280 mmHg and a frequency of 6–63 cycles per minute.

Dear Linda Li:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: The Center for Devices and Radiological Health (CDRH) does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, the Food and Drug Administration (FDA) may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-devices/medical-device-safety/medical-device-reporting-mdr-how-report-medical-device-problems.
