No
The device is a nasal retainer designed to keep nasal passages open and reduce swelling after surgery; it does not diagnose medical conditions.
No
The device description clearly states it is a physical silicone U-shaped device with tubes inserted into the nostrils, indicating it is a hardware medical device.
Based on the provided information, the Porex Nostril Retainer is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body. This device is a physical retainer inserted into the nasal passages.
- The intended use is for post-surgical support and maintaining open nasal passages. This is a therapeutic and supportive function, not a diagnostic one.
- The device description clearly outlines a physical object for insertion. There is no mention of analyzing biological samples.
The Porex Nostril Retainer is a medical device, but it falls under a different category than IVDs.
