3M™ VFlex™ Health Care Particulate Respirator and Surgical Mask 1804/1804S is intended to be worn by operating room personnel during surgical procedures to protect both the surgical patient and operating room personnel from transfer of microorganisms, body fluids, and particulate material.
The 3M™ VFlex™ Health Care Particulate Respirator and Surgical Mask, Models 1804/1804S are provided as a flat-folded Surgical N95 Respirator composed of multi layers of materials consisting of polypropylene spunbond (inner web), polypropylene (filter web), polypropylene spunbond (outer web). The product contains an aluminum nose clip within the layers of the top edge of the product to conform to the contours of the face. In addition, the product contains two steel staples used to secure the two polyisoprene elastic headbands (not made with natural rubber latex) to the product and the headbands are to secure the product in place on the wearer. The products are provided only in white and provided in two sizes one being small.
The 3MM VFlex™ Health Care Particulate Respirator and Surgical Mask, 1804/1804S is an particulate respirator. Particulate respirators help reduce the wearer exposure to certain airborne particles. including those generated by electrocautery, laser surgery and other powered medical instruments. This respirator has a filter efficiency level of at least 95% against particulate aerosols free of oilt. As a surgical mask, it is designed to be fluid resistant to splash and spatter of blood and other infectious materials and meets >99% bacterial filtration efficiency (BFE) ±. It is cleared to be worn in surgery. It can fit a wide range of face sizes. CDC guidelines state N95 respirators may be used for M. tuberculosis. *
This document is a 510(k) Premarket Notification for a medical device: 3M™ VFlex™ Health Care Particulate Respirator and Surgical Mask, Models 1804/1804S. The purpose of this submission is to demonstrate substantial equivalence to a legally marketed predicate device (3M™ Health Care Particulate Respirator and Surgical Mask, Model 1870).
The provided text describes the device, its intended use, and a comparison to a predicate device based on various features and performance specifications. However, this document does not describe a study involving an AI/Machine Learning device, human readers, or image analysis for medical diagnosis. It details the acceptance criteria and performance data for a physical product, specifically a surgical mask/respirator.
Therefore, many of the questions regarding AI/ML study design (such as sample size for test/training sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, and how ground truth was established for training) are not applicable to this type of device submission.
Here's a breakdown of the information that is relevant to the provided text, structured as requested where possible:

§ 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.
