Medical Protective Masks is intended to be worn to protect both the patient and healthcare persomel from transfer of microorganisms, body fluids and particulate material. It 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(s), provided non sterile.
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 ear straps are held in place over the users' mouth and nose by two elastic ear straps welded to the facemask. The elastic ear straps are not made with natural rubber latex. The nose piece on the layers of facemask is to allow the user to fit the facemask around their nose, which is made of PE (polyethylene) with dual-Galvanized wire. The mask is a single use, disposable device, provided non-sterile in black color.
The provided document (K223686) is a 510(k) Premarket Notification for Medical Protective Masks. This document focuses on demonstrating substantial equivalence to a predicate device, primarily through non-clinical performance testing and material comparisons.
It is crucial to understand that this document describes the regulatory acceptance of a medical mask device, NOT an AI/ML-driven device. Therefore, many of the requested fields regarding AI/ML-specific details (like training/test sets, ground truth establishment for AI, expert adjudication, MRMC studies, and standalone AI performance) are not applicable to this submission. The "study" referenced in the prompt (as proving the device meets acceptance criteria) refers to the non-clinical performance testing of the physical mask, not a clinical or AI-based study.
Here's the information extracted from the document relevant to the performance of the Medical Protective Masks:
1. Table of Acceptance Criteria and Reported Device Performance (Non-Clinical)
| Item | Acceptance Criteria (Level 2, ASTM F2100-19) | Reported Device Performance | Result |
|---|---|---|---|
| Bacterial filtration efficiency (BFE) (%) | ≥98 | 99.0%-99.8% | Pass |
| Differential pressure (mmH2O/cm²) |
§ 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.
