Intended Use

The Medical Protective Mask is intended to be worn to protect both the patient and healthcare personnel from transfer of microorganisms, body fluids and particulate material. The Medical Protective Mask is 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 Description

The Medical Protective Mask is a single use, two-panel, flat-folded mask with ear loops and nose piece. The mask is designed into a C-shape when flat-folded. The C-shaped design allows for an expanded chamber for the mask in use. The mask materials include four layers, the inner and outer layers are made of spun-bond polypropylene, and the two middle layers are melt-blown polypropylene and non-woven polypropylene filters, respectively. The elastic ear loops are made of spandex and polyester, which are welded to the facemask to hold the mask in place over the users' mouth and nose. The elastic ear loops are not made with natural rubber latex. The nose piece is a Iron core covered with polypropylene. The dimensions of each mask are length 162±5 mm and width 102±5 mm. The dimensions of nosepiece is length 90±10 mm and width 5±0.5 mm, and the ear loop is length 185±5 mm and width 5±0.5 mm. The mask is a single use, disposable device, provided non-sterile in white color.

AI/ML Overview

This document is an FDA 510(k) premarket notification for a medical protective mask. It does not describe an AI medical device or an MRMC study. Therefore, most of the requested information regarding acceptance criteria and studies proving device performance, especially those related to AI and human reader improvement, cannot be extracted from this document.

However, I can provide the acceptance criteria and reported performance for the physical and biological characteristics of the medical protective mask based on the provided text.

Here's the relevant information that can be extracted:

Information Not Applicable or Not Found in the Document:

The provided document is a 510(k) premarket notification for a Medical Protective Mask, which is a physical device, not an AI/software-based medical device. Therefore, the following points related to AI, imaging, and clinical studies are not applicable or not found in this document:

  1. Sample size used for the test set and the data provenance: Not applicable for this type of device and testing. The performance tests are laboratory-based, often using standard samples or methods (e.g., bacterial aerosols, synthetic blood).
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for masks is established by standardized laboratory test methods, not expert clinical interpretation.
  3. Adjudication method: Not applicable.
  4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done: Not applicable. This is for AI-assisted image interpretation, not mask performance. The document explicitly states "No clinical study is included in this submission."
  5. If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable. This refers to AI algorithm performance.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): The ground truth for this device's performance is based on standardized laboratory test methods and established measurement criteria (e.g., ASTM F2101 for BFE, ASTM F2299 for PFE, ASTM F1862 for fluid resistance, ISO 10993 for biocompatibility).
  7. The sample size for the training set: Not applicable, as this is a physical device, not an AI model requiring a training set.
  8. How the ground truth for the training set was established: Not applicable.

Dear Cassie Lee:

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.

§ 878.4040 Surgical apparel.

(a)
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.(b)
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.
