More Information

No
The device description and performance studies focus on the physical properties and filtration capabilities of a surgical mask, with no mention of AI or ML.

No

The device is a surgical mask intended for protection and infection control, not for treating or curing a medical condition.

No

The device is a surgical mask which serves as a barrier to protect against microorganisms and body fluids. It does not perform any diagnostic function.

No

The device description clearly states it is a physical mask composed of multiple layers and ear loops, indicating it is a hardware device, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Function: The description clearly states the device is a surgical mask intended to be worn on the face to protect against the transfer of microorganisms, body fluids, and particulate material. It acts as a physical barrier.
  • Lack of Specimen Analysis: There is no mention of the mask being used to analyze any biological specimens. Its function is external and protective.

The information provided focuses on the physical properties and performance of the mask as a barrier, not on any diagnostic testing of biological samples.
