The device description and performance studies focus on the electrostatic properties of a gel and its ability to physically block allergens, with no mention of AI or ML technologies.
Yes
The device is intended to alleviate mild allergic symptoms. Its mechanism of action involves interacting with airborne allergens to prevent them from entering the nasal passages. This function goes beyond mere general wellness, as it actively addresses a specific health-related condition (allergic symptoms) by blocking causative agents. The performance studies and comparison to a predicate device for allergic rhinitis further support its classification as a therapeutic device.
No
The device is intended to alleviate symptoms of allergies by blocking allergens, not to diagnose or detect medical conditions.
No
The device description clearly states that NasalGuard is a water-based gel, which is a physical substance, not software.
Based on the provided information, NasalGuard is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- NasalGuard's Function: NasalGuard is a topical gel applied to the outside of the nasal passages. Its mechanism of action is to physically block airborne allergens from entering the nasal passages using an electrostatic field. It does not analyze any bodily fluids or tissues.
- Intended Use: The intended use is to alleviate mild allergic symptoms by preventing allergens from entering the body, not by analyzing a sample from the body.
- Device Description: The description clearly states it's a topical gel applied externally.
- Performance Studies: The studies described focus on the reduction of allergic symptoms and the ability to capture allergens, not on analyzing biological samples.
Therefore, NasalGuard falls under the category of a medical device, but not specifically an In Vitro Diagnostic device.

Device Description
NasalGuard is a water-based gel consisting of common, GRAS cosmetic grade ingredients. The product is applied by finger or cotton swab to the outside of the masal passages, around the nostrils and upper lip. NasalGuard utilizes a patented methodology that uses the cationic properties of its ingredients to create an memodology that assess the causens ne allergens before they enter the nasal passages. The gel is considered innocuous and does not penetrate the dermal layer of the skin. The get is concrease on lasts for 4-6 hours before the gel has to be reapplied. NasalGuard is intended for topical use and provided non-sterile.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A double blind, crossover study of 43 subjects with known allergic rhinitis condition r r double of the use of NasalGuard showed significant efficant efficacy during the trial in reducing allergic rhinitis symptoms compared with an active control.
These test data has been statistically analyzed as per the Alergol clinical study criteria.
The chi-square test has p-value = 0.7974, which indicates that no statistically significant difference exists between these two treatments. However, the results indicate a somewhat more efficacious trend for the NasalGuard compared with Alergol.
