Medical surgical mask is intended for use by healthcare workers during procedures to protect both patients and healthcare workers against transfer of microorganisms, bodily fluids, and particulate matters. This device is single use and provided non-sterile.
The medical surgical mask (model: Black mask, Level 3) is a flat pleated style mask with ear loops, and a nose piece design for fitting the mask around the nose. The mask is manufactured with three layers, the inner and outer layers are made of polypropylene, and the middle layer is made of melt-blown polypropylene. Ear loops are held to cover the users' mouth and nose by two polypropylene bands ultrasonically welded to the mask. The elastic ear loops are not made with natural rubber latex. The nose piece included in the mask is in the middle layer of the mask, to allow the user to fit the mask around their noses. The mask will be provided in black color, the colorant for the masks is Carbon black (CAS No.1333-86-4).
The subject device has 2 kinds of dimensions: 17.5 cm x 9.5 cm and 14.5 cm x 9.5 cm, and 2 kinds of protection performance: Level 1 and Level 3.
The mask is sold non-sterile and intended to be a single-use, disposable device.
The requested information pertains to a medical surgical mask, which is a physical device, not an AI/ML powered device. Therefore, acceptance criteria and study details relevant to AI/ML powered devices are not applicable.
However, based on the provided document, I can extract the acceptance criteria and performance data for the physical medical surgical mask for Level 1 and Level 3 performance, as well as biocompatibility testing.
Here's the relevant information about the acceptance criteria and the study that proves the device meets these criteria, focusing on the available context for a physical medical surgical mask:
1. A table of acceptance criteria and the reported device performance
Medical Surgical Mask (Level 1)
| Test Item | Acceptance Criteria | Reported Device Performance |
|---|---|---|
| Bacterial Filtration Efficiency | ≥ 95% | 32/32 Passed at ave. 99.3% |
| 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.
