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 is flat pleated style mask, utilizing ear Loops way for wearing, and they all have nose piece design for fitting the Medical surgical mask around the nose. The Medical surgical mask is manufactured with three layers, the inner and outer layers are made of spun bond polypropylene, only the outer layers' color is blue (colorant: Pigment Blue K6911D /CAS number: 12239-87-1), and the middle layer is made of melt blown polypropylene. Ear loops, which is held to cover the users' mouth and nose by two polyester and spandex elastic bands ultrasonic welded to the Medical surgical mask. The elastic ear loops are not made with natural rubber latex. The nose piece contained in the Medical surgical mask is in the middle layer of Medical surgical mask to allow the user to fit the Medical surgical mask around their noses, which is made of metallic iron wire coated with polypropylene resin. The dimensions of each Medical surgical mask are length 175±5 mm and width 95±2 mm, and the inner and outer layers' density are 25 gsm, the middle layer is 35 gsm. The dimensions of nosepiece is length 100±5 mm and width 3±0.5 mm, and the ear loop is length 175±10 mm and width 3.5±0.5 mm. The Medical surgical mask is sold non-sterile and is intended to be single use, disposable device.
The document provided describes the acceptance criteria and performance of a Medical Surgical Mask (Model: KF-B P05) by Guangdong KINGFA Sci.&Tech.Co.,Ltd. Rather than an AI device being proven to meet acceptance criteria, this is a 510(k) summary for a medical device (a mask) demonstrating substantial equivalence to a predicate device through non-clinical testing.
Here's the breakdown of the information requested, based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
The device is evaluated against ASTM F2100:2019 Level 1 performance requirements.
| Test Item (Performance Level 1) | Acceptance Criteria (Pass Criteria) | Reported Device Performance (Test Results) |
|---|---|---|
| Bacterial Filtration Efficiency (BFE) | ≥ 95% | 99.2% |
| 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.
