Roosin Xeroform Petrolatum Dressing is intended for use as a primary contact layer in dressing wounds such as lacerations, skin graft recipient sites, newly sutured wounds, abrasions, and minor or partial thickness burns. It may also be used as an initial layer in dressing surgical wounds with light exudate.
Roosin Xeroform Petrolatum Dressing is a type of wound dressing and has ingredients of finely woven mesh gauze infused with a blend of petrolatum and 3% Bismuth Tribromophenate. It is a sterile, single use dressing. This is a combination product. Roosin Xeroform Petrolatum Dressing is used as a primary contact layer in dressing for wounds such as lacerations, skin graft recipient sites, newly sutured wounds, abrasions, and minor or partial thickness burns. The dressing has a yellow appearance and is available in the form of pad and in four different sizes (2" x 2", 1" x 8", 4" x 4", 5" x 9"), packaged in pouches. All dressings are sterilized by gamma radiation using conditions validated following ISO 11137-2: 2013.
The provided document describes a 510(k) premarket notification for a medical device called "Roosin Xeroform Petrolatum Dressing." This document does not contain information about acceptance criteria or a study proving that a device meets such criteria, especially not in the context of an AI/algorithm-based medical device.
The document details the device's intended use, materials, manufacturing, and a comparison to a predicate device (K152970: "Dynarex Xeroform Petrolatum Dressing") to establish substantial equivalence. The "performance tests" mentioned are likely related to general medical device standards (e.g., sterilization, biocompatibility, material properties) rather than specific clinical performance metrics that would involve complex data analysis, ground truth establishment, or human reader studies typically associated with AI/ML-driven devices.
Therefore, I cannot provide the requested information for the following reasons:
- No AI/Algorithm Component: The device described is a wound dressing, which is a physical product, not an AI or algorithm.
- No Performance Study as Described: The document mentions "Performance tests were conducted following in house procedures, and results for Roosin Xeroform Petrolatum Dressing met all relevant requirements, and are comparable to the predicate devices." However, these are general performance tests, not a clinical study involving a test set, ground truth, experts, or MRMC studies as outlined in your request.
- No Acceptance Criteria for AI Performance: Since it's not an AI device, there are no acceptance criteria for AI performance metrics (like sensitivity, specificity, AUC, human reader improvement, etc.).
In summary, the provided text does not contain the information necessary to answer your request about acceptance criteria and a study proving an AI/algorithm device meets those criteria.

Dear Charles Shen:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part
{1}------------------------------------------------
801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
