Intended Use

The Maxxi Snore Sensor is a device intended to acquire snore bursts. It responds to snoring and other sounds in the audio range picked up through the skin and convert them to a small analog voltage that provides an indication of the presence of these sound/vibration bursts. This sensor is intended to be used with polysomnography devices and adult patients. Intended to be use in a sleep laboratory, clinics or hospitals.

Device Story

Piezoelectric sensor captures mechanical vibrations/sounds from patient neck surface during sleep; converts vibrations into small analog voltage signals; output transmitted via DIN 42-802 connector to polysomnography (PSG) recording device. Used in sleep labs, clinics, or hospitals by clinicians; output displayed as snore bursts on PSG monitor; assists physicians in qualifying/quantifying snoring events to diagnose sleep disorders. Benefits include non-invasive monitoring of respiratory sounds to support clinical decision-making.

Clinical Evidence

Bench testing only. Comparative performance testing against the predicate device evaluated dimensions, cable length, visual conditions, and signal output (frequency and amplitude). Results demonstrated that the Maxxi Snore Sensor provides equivalent signals within acceptable ranges (±15% for frequency/amplitude) compared to the predicate.

Technological Characteristics

Piezoelectric sensing element; TPC-ET (thermoplastic elastomer) housing; insulated Teflon wire; DIN 42-802 touch-proof connector. Signal output: AC signal, 0-500 Hz frequency range, 0-500uV amplitude sensitivity. Dimensions: 18mm sensor diameter, 3ft/7ft cable lengths. Complies with ISO 13485:2003, ISO 10993 (biocompatibility), IEC 60601-1.

Indications for Use

Indicated for adult patients undergoing polysomnography in sleep laboratories, clinics, or hospitals to acquire snore bursts for the assessment of sleep-disordered breathing.

Regulatory Classification

Identification

A breathing (ventilatory) frequency monitor is a device intended to measure or monitor a patient's respiratory rate. The device may provide an audible or visible alarm when the respiratory rate, averaged over time, is outside operator settable alarm limits. This device does not include the apnea monitor classified in § 868.2377.
