## Device Name:

| Proprietary name: | Weinmann SOMNOmask |
|-------------------|--------------------|
|-------------------|--------------------|

Common Name: Nasal mask

Classification Name: Accessory to non-continuous ventilator

#### Predicate Device Equivalence:

Substantial equivalence is claimed to the Respironics Reusable Contour II Nasal Mask and to the Puritan-Bennett Breeze SleepGear with DreamSeal, cleared for commercial distribution per K991648 and K002001, respectively.

# Device Description:

The Weinmann SOMNOmask comes in three sizes, small, medium and large. It has a removable mask seal.

Because the Weinmann SOMNOmask does not contain any ports or vents for removing the CO2 buildup, an external exhalation device must be used.

Image /page/1/Picture/0 description: The image shows the word "WEINMANN" in a bold, sans-serif font. There are two diagonal lines that intersect the letters "M" and "A", creating a unique visual element. The text is black and the background is white, providing a clear contrast. The overall design is simple and modern.

The SOMNOmask is secured to the patient's head with a 4-point headgear called the SOMNOstrap.

#### Intended Use:

The Weinmann SOMNOmask is intended for prescription use to be used during nasal CPAP or Bi-level Positive Pressure therapy for adult patients (>30 KG).

# Comparison of Technological Characteristics:

The Weinmann SOMNOmask has the same technological characteristics as the predicate devices.

# Summary of Device Testing:

A drop test, operating and storage temperature testing and flow resistance testing were performed to ensure that the SOMNOmask met its specifications.

#### Conclusions:

Based on the above, we concluded that the Weinmann SOMNOmask is substantially equivalent to legally marketed predicate devices and is safe and effective for its intended use.
