The Disposable Surgical Face Masks (model: ZYD-02&ZYD-03) are intended to be worn to protect both the patient and healthcare personnel from transfer of microorganisms, body fluids and particulate material. These face intended for use in infection control practices to reduce the potential exposure to blood and body fluids. This a single use, disposable device(s), provided non-sterile.
Disposable Surgical Face Mask Model No.: ZYD-02 and ZYD-03
This document is a marketing authorization letter from the FDA for a disposable surgical face mask. It verifies that the device is substantially equivalent to legally marketed predicate devices.
The document does not contain information about acceptance criteria or a study that proves the device meets the acceptance criteria in the context of an AI/ML medical device. The information provided relates to regulatory clearance of a physical medical device (surgical face mask) based on substantial equivalence, not performance evaluation of an AI algorithm.
Therefore, I cannot answer your request based on the provided text. The questions you've asked (regarding multi-reader multi-case studies, standalone algorithm performance, training/test set sample sizes, expert ground truth, etc.) are germane to the evaluation of AI/ML-driven medical devices, for which this document provides no relevant data.
§ 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.
