Surgical Gowns are intended to be worn by operating room personnel during surgical procedures to protect the surgical patient and operating room personnel from the transfer of microorganisms, body fluids and particulate material. This surgical gown meets the requrements of AAMI Level 3 barrier protection for a surgical gown per ANSI/AAMI PB70:2012 Liquid barrier performance and classification of protective apparel and drapes intended for use in health care facilities (AAMI PB70). The Surgical Gowns are single use, disposable medical devices; provided non-sterile. Before the use, the Surgical Gowns must be sterilized by EO sterilization based on ISO 11135:2014.
The Surgical Gown is composed of collar, body, sleeve and tie, in a blue color, offered in sizes S, M, L, XL and XXL. The neck and waist are laced, the sleeves are made of polyester elastic closure by sewing, and the rest are made of heat sealing. It has been tested according to AAMI PB70:2012 and meet AAMI Level 3 barrier level protection for a surgical gown.
Here's a summary of the acceptance criteria and the study that proves the device meets them, based on the provided text:

2. Sample Size Used for the Test Set and Data Provenance:
The document does not explicitly state the specific sample sizes used for each individual test (e.g., how many gowns were tested for impact penetration). It only states that the device "was tested and conformed to the related recognized standards." The provenance of the data is implied to be from testing conducted by or for Hubei Woozon Healthcare Co.,Ltd. The document does not specify the country of origin of the data or whether the tests were retrospective or prospective, beyond stating that they were non-clinical tests.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
Not applicable. This device is a surgical gown, and its performance is evaluated through standardized physical, chemical, and biological barrier tests, not through expert human interpretation of medical images or data requiring ground truth establishment by medical experts.
4. Adjudication Method for the Test Set:
Not applicable. As described above, the evaluation relies on adherence to standardized test methods and their defined pass/fail criteria, rather than expert adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size:
No. This type of study is not relevant for the evaluation of a surgical gown. MRMC studies are typically conducted for AI/CAD systems that assist human readers in interpreting medical images.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done:
Not applicable. The "device" in this context is a physical product (surgical gown), not an algorithm or AI system. Its performance is inherent to the product itself, not an algorithmic output.
7. The Type of Ground Truth Used:
The "ground truth" for the surgical gown is established by the specified performance requirements and limitations outlined in the recognized standards (e.g., AAMI PB70, AATCC, ASTM, ISO, 16 CFR). These standards define the acceptable levels of barrier protection, strength, flammability, and biocompatibility. The results of the tests conducted directly against these standards serve as the evidence that the device meets the "ground truth" requirements.
8. The Sample Size for the Training Set:
Not applicable. This device is a manufactured product, not an AI/machine learning model that requires a training set.
9. How the Ground Truth for the Training Set Was Established:
Not applicable, for the same reason as point 8.

§ 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.
