## Indications for Use

The Surgical face masks are intended to be worn to protect both the patient and healthcare personnel from transfer of microorganisms, body fluids, and particulate material. These face masks are intended for use in infection control practices to reduce the potential exposure to blood and body fluids. This is a single-use, disposable device, provided non-sterile.

## Device Story

Surgical face mask; flat-pleated, three-layer sandwich structure; inner/outer layers polypropylene nonwoven; middle layer polypropylene melt-blown nonwoven; nosepiece galvanized iron wire with PE coating; attachment via spandex elastic ear loops or polypropylene nonwoven tie straps. Device acts as self-inhalation filter mask; filters air containing harmful substances before inhalation/exhalation. Used in clinical settings for infection control; worn by healthcare personnel and patients. Provides barrier protection against microorganisms, body fluids, and particulate aerosols. Single-use, disposable, non-sterile.

## Clinical Evidence

No clinical data. Bench testing only. Performance testing included Bacterial Filtration Efficiency (BFE), sub-micron particle filtration efficiency, differential pressure, flammability (Class 1), and synthetic blood penetration resistance (120 mmHg for Level 2; 160 mmHg for Level 3). Biocompatibility testing included cytotoxicity (ISO 10993-5), sensitization (ISO 10993-10), skin irritation (ISO 10993-10), and acute systemic toxicity (ISO 10993-11). Simulated transportation testing per ASTM D4169 passed.

## Technological Characteristics

Three-layer polypropylene nonwoven construction; middle layer polypropylene melt-blown nonwoven. Nosepiece: galvanized iron wire with PE coating. Attachments: spandex elastic (ear loops) or polypropylene nonwoven (tie straps). ASTM F2100-19 Level 2 and Level 3 performance. Non-sterile. Latex-free. Dimensions: 17.5 cm x 9.5 cm.

## Regulatory Identification

Surgical apparel are devices that are intended to be worn by operating room personnel during surgical procedures to protect both the surgical patient and the operating room personnel from transfer of microorganisms, body fluids, and particulate material. Examples include surgical caps, hoods, masks, gowns, operating room shoes and shoe covers, and isolation masks and gowns. Surgical suits and dresses, commonly known as scrub suits, are excluded.

## Special Controls

*Classification.* (1) Class II (special controls) for surgical gowns and surgical masks. A surgical N95 respirator or N95 filtering facepiece respirator is not exempt if it is intended to prevent specific diseases or infections, or it is labeled or otherwise represented as filtering surgical smoke or plumes, filtering specific amounts of viruses or bacteria, reducing the amount of and/or killing viruses, bacteria, or fungi, or affecting allergenicity, or it contains coating technologies unrelated to filtration (e.g., to reduce and or kill microorganisms). Surgical N95 respirators and N95 filtering facepiece respirators are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 878.9, and the following conditions for exemption:(i) The user contacting components of the device must be demonstrated to be biocompatible.
(ii) Analysis and nonclinical testing must:
(A) Characterize flammability and be demonstrated to be appropriate for the intended environment of use; and
(B) Demonstrate the ability of the device to resist penetration by fluids, such as blood and body fluids, at a velocity consistent with the intended use of the device.
(iii) NIOSH approved under its regulation.
(2) Class I (general controls) for surgical apparel other than surgical gowns and surgical masks. The class I device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 878.9.

Dear Olivia Meng:

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 (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 located 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: 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, FDA may publish further announcements concerning your device in the Federal Register.

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

{1}------------------------------------------------

#### 4. DEVICE DESCRIPTION

The Surgical face mask is designed and manufactured by Foshan Nanhai Plus Medical CO LTD. It is non-sterile and for single use.

The Surgical face mask is a sandwich structure with the inner and outer layer of polypropylene nonwoven. The middle layer is polypropylene melt-blown nonwoven which provides barrier protection to microorganism, body fluid and particulate aerosol transfer. The ear loop is made with polypropylene nonwoven (tie strap type) or spandex elastic (ear loop type). The Surgical face mask is latex free.

lt is a self-inhalation filter mask, which works by filtering the air containing harmful substances through the filter material of the mask before being inhaled or exhaled.
