Disposable Medical Face Mask is intended to be worn to protect both the patient and healthcare personnel from transfer of microorganisms, body fluids and particulate material. This face mask is intended for use in infection control practices to reduce the potential exposure of the wearer to blood and body fluids. The mask is a single use, disposable device, provided non-sterile.
The Disposable Medical Face Mark is blue color, and flat pleated type mask, utilizing ear loops or tie-on way for wearing, and has nose strip design for fitting the facemask around the nose. The colorant used in the mask outer layer is blue: Copper phthalocyanine/ CAS number: 147-14-8). The proposed device is manufactured with three layers, the inner and outer layers made of spunbond polypropylene, and the middle layer is made of melt blown polypropylene filter. The model DY 96, tie-on, is held in place over the user's mouth and nose by four straps welded to the facemask. The straps are made of Spun-bond polypropylene. Its dimension is 17.5x9.5cm, strap is 38 cm, nose strip is 9.5±0.5 cm.
The models MK-34, DY 95 and DY 97, ear loops, are held in place over the user's mouth and nose by two elastic ear loops welded to the facemask. The elastic ear loops are made of Nylon and Spandex, not made with natural rubber latex. The dimension of MK-34 is 14.5x9.5cm, ear loop is 13cm, nose strip is 9.5±0.5 cm. The dimension of DY 95 and DY 97 is 17.5x9.5cm, ear loop is 13 cm, nose strip is 9.5±0.5 cm.
The nose strip contained in the proposed device is in the layers of facemask to allow the user to fit the facemask around their nose, which is made of PE and galvanized iron wire.
The device is sold non-sterile and are intended to be single use, disposable device.
This document is a 510(k) premarket notification for a Disposable Medical Face Mask, not a study describing the performance of a medical device against specific acceptance criteria in the context of an AI/human reader study. Therefore, most of the questions regarding acceptance criteria and study design for AI/human performance are not applicable.
However, I can extract the acceptance criteria and reported performance for the Disposable Medical Face Mask based on non-clinical testing of the physical characteristics of the mask.
Here's the information based on the provided text, focusing on the mask's non-clinical performance and not on AI/human reader studies.
1. A table of acceptance criteria and the reported device performance
| Test Item | Acceptance Criteria (ASTM F2100 Level 2) | Reported Device Performance (MK-34, DY 95, DY 97) | Reported Device Performance (DY 96) | Met Criteria? |
|---|---|---|---|---|
| Bacterial Filtration Efficiency (BFE) | ≥ 98% | 99.8% | 99.9% | Yes |
| Differential Pressure (Delta-P) |
§ 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.
