No
The description focuses on hardware components (sensor, cable, SIM) and basic software functions for data collection, transmission, storage, processing, and display. There is no mention of AI, ML, or advanced analytical techniques beyond basic signal processing and comparison to PSG data.
No.
The device is intended as a screening device to assess and record nasal and oral airflow to determine the need for clinical diagnosis and evaluation, rather than to provide therapy or treatment.
Yes
The device is intended as a screening device to determine the need for clinical diagnosis and evaluation by polysomnography (PSG) based on the patient's test data, which indicates it helps in identifying conditions for further diagnostic investigation.
No
The device description explicitly states it is comprised of 3 physical components (Airflow sensor, cable, and SIM) in addition to the software.
Based on the provided information, the Rubicon screening device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The Rubicon device directly measures physiological signals (airflow and snoring) from the patient's body (nasal and oral airflow). It does not analyze samples like blood, urine, or tissue.
- The device description focuses on sensors and signal processing. The core technology involves converting physical changes (temperature and pressure) into electrical signals and processing these signals. This is characteristic of a physiological monitoring device, not an IVD.
- The intended use is to assess and record airflow during sleep. This is a direct measurement of a physiological function, not an analysis of a biological specimen to diagnose a disease or condition.
- The device is used in the home setting by the patient. While the data is intended for a healthcare professional, the initial data collection is done directly on the patient.
In summary, the Rubicon screening device is a physiological monitoring device used to collect data directly from the patient's body, not an IVD which analyzes specimens from the body.

Device Description
The Rubicon Screening Device is comprised of 3 components and software. For the physical device. Rubicon is comprised of an Airflow sensor, cable connecting air flow sensor and a single inline module (SIM) as described below:
Airflow sensor
The airflow sensor is placed under the user's nose where it converts temperature and pressure changes to a voltage signal. Polarized Polyvinylidene Fluoride (PVDF) is a temperature-sensing material. PVDF generates a small electrical charge in response to temperature change.
The sensor is permanently connected to the SIM via two lead wires.
The temperature difference between patient exhaled air and ambient air, as well as airflow pressure on the sensor generates a small voltage signal, which can be recorded as airflow by recording equipment. The vibration of breath sounds (snoring) produces a small voltage signal, which can be recorded as snoring by recording equipment.
As integrated into the Rubicon, the airflow sensor provides two channels of output data from the same PVDF sensor. One channel focuses on sinusoidal airflow waveforms for identification of airflow events, and the second channel provides snore data.
Cable
The lead wires are a typical cable pair. The lead wires were reviewed as part of the IEC 60601-1 safety evaluation. The lead wires transmit signals from the airflow sensor to the SIM and are permanently attached to the airflow sensor and the SIM.
SIM (Housing and PCB)
The SIM's primary function is to collect raw electrical signals from the airflow sensor. These signals include airflow and snore analog data. These analog signals are filtered and acquired by the SIM's A/D converter, then transmitted in real time to a nearby Smartphone, which must be running the Rubicon companion app. The SIM PCB is powered by a small coin cell battery.
Software
The basic purpose of the software is to:
- Collect data from the sensor device by transmitting the data to a collection hub, which is a Smartphone + a mobile software application (app).
- Transmit data to a remote data center, which is accomplished via thecellular network.
- . Store, process, and display data to a health care professional or end user via the Rubicon Analysis Software PC application and its report.
The system consists of three major components: Sim Software (firmware), Rubicon App and Rubicon Desktop Software

V Indications for use:
The Rubicon screening device is a small battery-powered device designed to assess and record nasal and oral airflow in adult patient during sleep in the home setting. The device is intended as a screening device to determine the need for clinical diagnosis and evaluation by polysomnography (PSG) based on the patient's test data.
Patient Population: This device is used only by adults during their sleep
Environments of use: Home settings
The following table presents the comparison to support substantial equivalence.
Table 1 compares the key features of the proposed Rubicon with the identified predicate -K022294- IMS SleepCheck and reference K040069 - Dymedix Air Flow Sensor and demonstrates that this proposed device can be found substantially equivalent.
In summary, one can conclude that substantial equivalence is met based upon the following:
Indications for Use – The Indications for Use are similar. The subject device is only a screening tool which is detecting airflow events based upon airflow characteristics, whereas the predicate also collects airflow data and reports apnea and hypopnea breathing events and is considered a screening tool.
5
We are not diagnosing but reporting detected airflow events for further consideration by the clinician.
Technology and construction - The technology and construction are similar to predicate in that we are utilizing an airflow sensor to detect breathing events. The employed airflow sensor is identical to the reference. K040069, device which has been cleared for the same intended use. There are no differences in the breathing event detection technology.
The subject device transmits data via BLE to an app. However, transmission of data via wireless technology is not new or novel and does not change the risk profile beyond what is already recognized by FDA as acceptable when applicable testing has been provided.
Environment of Use - The environments of use are similar - home settings.
Patient Population - The patient population is similar to the predicate namely, adults.
