The device description and performance studies focus on the physical properties and filtration capabilities of surgical masks, with no mention of AI or ML technology.
No
Explanation: The device is a surgical mask intended for protection against microorganisms and fluids, not for treating any medical condition.
No
The device is described as surgical masks intended to protect against the transfer of microorganisms, body fluids, and particulate material. Its intended use focuses on physical barriers and filtration, not on diagnosing medical conditions or diseases.
No
The device description clearly outlines physical components like spunbond polypropylene, meltblown polypropylene, spandex, PET, iron wire, and polypropylene, indicating it is a hardware device (surgical masks).
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the masks are for protecting both the patient and healthcare personnel from the transfer of microorganisms, body fluids, and particulate material. This is a physical barrier function, not a diagnostic test performed on samples taken from the body.
- Device Description: The description details the physical components and construction of the masks. There is no mention of reagents, assays, or any components used for analyzing biological samples.
- Performance Studies and Key Metrics: The performance studies and key metrics focus on the physical properties and barrier effectiveness of the masks (filtration efficiency, pressure resistance, flammability, resistance to blood penetration, and biocompatibility). These are not diagnostic performance metrics like sensitivity, specificity, or AUC, which are typical for IVDs.
- Lack of IVD Characteristics: There is no mention of analyzing samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information about a patient's health status.
In summary, the provided information describes a medical device designed to provide a physical barrier for infection control, not a device used to perform diagnostic tests on samples outside of the body.

Device Description
The surgical masks are single use, flat-pleated masks that are provided in blue. The outer and inner layers of the mask are made of spunbond polypropylene. The middle filter is made of one layer of meltblown polypropylene filter. The Surgical Masks are available in four types due to different configurations, including ear loop, tie-on, ear loop with shield and tie-on with shield. Detail configurations of them are presented in Table 1 Surgical Masks Description. The ties are made of spunbond polypropylene and the ear loops are made of spandex. The shield is made of PET. The nose piece is made of iron wire and polypropylene. Users can adjust the nose piece according to the shape of the bridge of the nose, and fix the mask on the bridge of the nose to prevent the mask from falling off. The proposed devices are provided in non-sterile. The proposed devices contain four (4) types of masks: XX0009, XX008, XX0006 and XX0005. Each of these types have three different levels, level 2, and level 3. Therefore, the proposed devices have 12 models in toto, and detailed model information is provided in Table 1.

(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.
