Disposable sterile drapes are used in the operating room as a protective covering, for both patient and operating room staff, from the transfer of body fluids, micro-organisms and particulates.
Drapes provided as sterile and non-sterile.
Non-sterile surgical drapes are to be sold to OEMs for EtO sterilization according to ISO 11135. Sterile Surgical Drapes are to be sold directly to users after EtO sterilization validation to ISO 11135.

2. Sample Size Used for the Test Set and Data Provenance
The provided document does not specify the exact sample sizes for each test mentioned above. It simply states "Data Generated" for each test. The document does not provide information regarding the country of origin of the data or whether the studies were retrospective or prospective.
3. Number of Experts Used to Establish Ground Truth and Qualifications
This information is not applicable. The device's performance was assessed against established international and national standards for material properties and biocompatibility, not against expert-established ground truth in a clinical setting.
4. Adjudication Method for the Test Set
This information is not applicable. The testing involved measurements against predefined physical and biological standards, not subjective expert adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
A multi-reader multi-case (MRMC) comparative effectiveness study was not conducted for this device. The device is a surgical drape, and its effectiveness is determined by its physical and biological properties as tested against industry standards, not by human reader performance with or without AI assistance.
6. Standalone Performance Study
Yes, a standalone performance study was done in the sense that the device's material properties and biocompatibility were evaluated independently against specified standards, without the involvement of human interpretation or AI. The tests listed in the table (Hydrostatic Pressure, Tensile Strength, Biocompatibility, etc.) represent the standalone performance evaluation of the product.
7. Type of Ground Truth Used
The "ground truth" for evaluating the Welmed Surgical Drapes was based on established industry and regulatory standards and test methods. These standards define the acceptable performance characteristics for surgical drapes (e.g., water resistance, tensile strength, flammability, biocompatibility). The device was deemed substantially equivalent to a predicate device based on its compliance with these objective standards.
8. Sample Size for the Training Set
This information is not applicable. The product is a physical medical device (surgical drape), not an algorithm or an AI-powered system that requires a "training set."
9. How the Ground Truth for the Training Set was Established
This information is not applicable as there is no training set for this device.
§ 878.4370 Surgical drape and drape accessories.
(a)
Identification. A surgical drape and drape accessories is a device made of natural or synthetic materials intended to be used as a protective patient covering, such as to isolate a site of surgical incision from microbial and other contamination. The device includes a plastic wound protector that may adhere to the skin around a surgical incision or be placed in a wound to cover its exposed edges, and a latex drape with a self-retaining finger cot that is intended to allow repeated insertion of the surgeon's finger into the rectum during performance of a transurethral prostatectomy.(b)
Classification. Class II (special controls). The device, when it is an ear, nose, and throat surgical drape, a latex sheet drape with self-retaining finger cot, a disposable urological drape, a Kelly pad, an ophthalmic patient drape, an ophthalmic microscope drape, an internal drape retention ring (wound protector), or a surgical drape that does not include an antimicrobial agent, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 878.9.
