The Disposable Medical 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.
The proposed device(s) are blue color, and Flat Pleated type mask, utilizing Ear Loops way for wearing, and they all have Nose Piece design for fitting the facemask around the nose. The proposed device(s) are manufactured with three layers, the inner and outer layers are made of spun-bond polypropylene, and the middle layer is made of melt-blown polypropylene filter. The model of proposed device, ear loops, is 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 piece contained in the proposed device(s) is in the layers of facemask to allow the user to fit the facemask around their nose, which is made of polyethylene coated steel wire. The proposed device(s) are sold non-sterile and are intended to be single use, disposable device.
The provided text describes the 510(k) premarket notification for a Disposable Medical Surgical Mask (K202511). This is a regulatory submission for a medical device, and as such, the "study" referred to is primarily a set of performance tests conducted to demonstrate substantial equivalence to a predicate device, rather than a clinical trial or an AI algorithm validation study.
Therefore, many of the requested elements regarding AI performance, human reader studies, and sophisticated ground truth establishment are not applicable to this type of medical device submission. The device in question is a physical product (a surgical mask), not an AI algorithm or diagnostic tool.
Here's the breakdown based on the provided document:
Acceptance Criteria and Reported Device Performance
The acceptance criteria are derived from recognized standards for surgical masks, primarily ASTM F2100 levels. The study demonstrates performance against these criteria.
| Item | Acceptance Criteria | Reported Device Performance | Result |
|---|---|---|---|
| Fluid Resistance Performance | 29 out of 32 pass at 160 mmHg | 32 out of 32 pass at 160 mmHg | Pass |
| Particulate Filtration Efficiency | $\ge$ 98% | 98.6% | Pass |
| Bacterial Filtration Efficiency | $\ge$ 98% | 99.9% | Pass |
| Differential Pressure (Delta-P) Test |
