Intended Use

The Surgical Masks are intended to be worn to protect both the patient and healthcare personnel from transfer of microorganisms, body fluids and particulate material. These face masks are 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.

Device Description

The Surgical Masks are blue color, single use, three-layer, flat -folded masks with nose clip and ear loops. The Surgical Masks are manufactured with three layers, the inner and outer layers are made of polypropylene spunbonded nonwoven, and the middle layer is made of polypropylene melt-blown nonwoven filter. The ear loops are held in place over the users' mouth and nose by two elastic ear loops welded to the facemask. The elastic ear loops are not made with natural rubber latex. The nose clip in the layers of facemask is to allow the user to fit the facemask around their nose, which is made of iron strip wrapped by plastic. The surgical masks are sold non-sterile and are intended to be single use, disposable devices.

AI/ML Overview

This document describes the non-clinical testing performed to demonstrate that the Allmed Medical Products Co., Ltd. Surgical Mask is substantially equivalent to a predicate device (K153496). The acceptance criteria and performance data are based on standard test methods for surgical masks.

1. Table of Acceptance Criteria and Reported Device Performance

ItemAcceptance Criteria (level 2)Reported Device Performance** (Proposed device)Result
Fluid Resistance ASTM F186229 out of 32 pass at 120 mmHg31, 30, 32 out of 32 pass at 120 mmHg, 3 lotsSimilar

Bacterial Filtration Efficiency (BFE) ASTM F2101≥ 98%Pass at 99.9%, 99.9%, 99.9%Similar

Flammability 16 CFR 1610Class 1Class 1Same
Cytotoxicity (ISO 10993-5)Non-cytotoxicUnder the conditions of the study, the device is non-cytotoxic.Same
Irritation (ISO 10993-10)Non-irritatingUnder the conditions of the study, the device is non-irritating.Same
Sensitization (ISO 10993-10)Non-sensitizingUnder the conditions of the study, the device is non-sensitizing.Same

Note: The term "Similar" in the "Result" column implies that the proposed device met or exceeded the performance of the predicate device and the specified acceptance criteria.

2. Sample Size Used for the Test Set and Data Provenance

  • Fluid Resistance (ASTM F1862): 3 lots were tested, with each lot likely consisting of 32 samples (as the criteria specifies "29 out of 32 pass"). Data provenance is not explicitly stated but implied to be from laboratory testing performed by or for the manufacturer.
  • Particulate Filtration Efficiency (ASTM F2299), Bacterial Filtration Efficiency (ASTM F2101), Differential Pressure (EN 14683 Annex C): The report indicates performance from multiple tests (e.g., three percentages for PFE/BFE, three pressure values for Delta P), suggesting at least 3 samples were tested for each.
  • Flammability (16 CFR 1610): Sample size not specified, but typically involves a set number of specimens from the material.
  • Biocompatibility (ISO 10993-5, -10): Sample sizes for "in vitro" and "in vivo" (for irritation/sensitization) tests are defined by the respective ISO standards, but not explicitly stated in this summary.

Data Provenance: The data appears to be from non-clinical laboratory testing (bench testing) of the device. The country of origin of the data is not explicitly stated, but the manufacturer is based in China. The testing is assumed to be prospective, performed specifically for this 510(k) submission.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

Not applicable. This is a submission for a surgical mask focusing on physical and biological performance characteristics measured through standardized laboratory tests, not subjective expert evaluation of data like medical image analysis. The "ground truth" is established by the specifications of the test standards themselves (e.g., a specific percentage filtration efficiency, a defined pressure drop).

4. Adjudication Method for the Test Set

Not applicable. This is not a study requiring adjudication of expert opinions. The performance is objectively measured by established laboratory test methods.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No. This type of study (MRMC) is typically used for diagnostic devices that involve human interpretation of medical images or data. Surgical masks are medical devices with mechanical and biological filtration properties, evaluated through non-clinical bench testing.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Yes, in essence. The core of this submission relies on "standalone" performance testing of the device itself (the surgical mask) against established standards. There is no "human-in-the-loop" component in evaluating the fundamental performance characteristics of the mask (e.g., BFE, PFE, fluid resistance).

7. The Type of Ground Truth Used

The ground truth for the device's performance is established by international and national consensus standards and regulatory guidelines (e.g., ASTM F2100, ASTM F1862, ASTM F2101, ASTM F2299, EN 14683, 16 CFR 1610, ISO 10993 series). These standards define the methodology and the acceptable performance thresholds for surgical masks.

8. The Sample Size for the Training Set

Not applicable. This is not an AI/ML device that requires a training set. The device is a physical product (surgical mask) whose performance is evaluated through specified tests.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there is no training set for this type of device.

§ 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.
