Intended Use
Disposable 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 requirements 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 sterile or non-sterile. Non-sterile gowns are to be sold to re-packager/re-labeler establishments for ethylene oxide (EtO) sterilization according to ISO 11135-1 prior to marketing to the end users and Sterile surgical gowns are to be sold directly to users after EtO sterilization validation to ISO 11135-1.
Device Description
Surgical Gown is designed for the medical personnel using in operation. The employed material is SMS compound non-woven fabric. The material has many good properties, such as soft, clean, good filtration and uniformity and waterproof, they are not sensitive to human beings, difficult to fluff, they don't have any peculiar smell, other matters and primary color. The gowns are for safe use in the operating room environment, i.e., lint free, free of toxic ingredients and non-fast dyes. It is a kind of Non- Reinforced surgical gown. The chest front and sleeve critical zones of the Disposable Surgical Gowns are constructed from a blue polyolefin SMS (spunbond, meltblown, spunbond) and have been tested according to AAMI PB70:2012 and meet AAMI Level 3 barrier level protection for a surgical gown. The Disposable Surgical Gown is a single use, disposable medical device that will be provided in a variety of nonsterile packaging configurations.

No
The device description and performance studies focus on the physical properties and barrier performance of a disposable surgical gown, with no mention of AI or ML technology.

No.
The device description and intended use clearly state that the disposable surgical gown is for protection and barrier, not for therapy or treatment of any medical condition.

No

Explanation: The device is a Disposable Surgical Gown, which is a protective apparel and not used for diagnosing medical conditions. Its purpose is to prevent the transfer of microorganisms, body fluids, and particulate material.

No

The device described is a physical surgical gown made of non-woven fabric, intended for use in operating rooms. The description focuses on material properties, barrier protection levels, and physical performance testing, with no mention of software components or functionality.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the gown is for protecting surgical patients and personnel from the transfer of microorganisms, body fluids, and particulate material during surgical procedures. This is a barrier function, not a diagnostic function.
  • Device Description: The description focuses on the material properties and construction of the gown for barrier protection. There is no mention of any components or functions related to testing samples from the human body.
  • Lack of IVD Indicators: The document does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing samples (blood, urine, tissue, etc.)
    • Detecting or measuring substances in samples
    • Providing information for diagnosis, monitoring, or screening

The device is a surgical gown, which is a type of personal protective equipment (PPE) used in a clinical setting. While it is a medical device, its function is protective and not diagnostic.

§ 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.

Dear Ivy Wang:

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

1

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 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). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
