Device Description
The Gereonics Ultra-Piezo Respiratory Effort Sensor is intended for use in Sleep Disorders Testing for the measurement of respiratory effort and frequency. It is designed for use with a bioamplifier attached to a physiological recording system. The Respiratory Effort Strap Sensor utilizes a processed polyvinylidene fluoride plastic film sensor as the detector for breathing motion. The small breathing deflection of the human body, typically measured on the stomach (abdomen) or chest (thorax), creates a small voltage in the piezoelectric plastic film sensor. There is no external voltage supply -- the sensor stressed by inhalation and exhalation directly converts motion to voltage. A passive low pass electronic filter is connected directly to the sensor and filters out frequencies above 15 Hertz to minimize noise and allow breathing frequencies to be monitored. The output from the passive filter, typically +/- 200 to 300 microvolts at 0.1 Hz, is connected to a bioamplifier in the physiological recording system where the signal is amplified for monitoring or recording. The sensor is secured to the body using a one inch wide strap system of Velcro hook and elastic loop material.
More Information

Not Found

No
The device description details a purely passive, analog sensor and filter system that converts physical motion into a voltage signal. There is no mention of any computational processing, algorithms, or learning capabilities.

No
The device is intended for measuring respiratory effort and frequency for monitoring or recording purposes in sleep studies, not for treating or preventing a disease or condition. It explicitly states it is "NOT intended for use as an Apnea Alarm," further indicating it's a diagnostic/monitoring tool rather than a therapeutic one.

Yes
The device is described as measuring respiratory effort for monitoring or recording in sleep disorders studies, which falls under the scope of diagnosing sleep-related breathing disorders. It measures physiological parameters to aid in medical assessment.

No

The device description explicitly details hardware components: a polyvinylidene fluoride plastic film sensor, a passive low pass electronic filter, and a strap system. It describes how these physical components interact to generate a voltage signal.

Based on the provided information, the Gereonics Ultra-Piezo Respiratory Effort Sensor is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device function: The Gereonics Ultra-Piezo Respiratory Effort Sensor measures respiratory effort by detecting the physical motion of the abdomen or chest. It does not analyze any biological samples taken from the body.
  • Intended Use: The intended use is for measuring respiratory effort in sleep disorders studies, which is a physiological measurement, not a diagnostic test performed on a sample.

Therefore, this device falls under the category of a physiological monitoring device, not an in vitro diagnostic device.

Device Description

The Gereonics, Inc. Ultra-Piezo Respiratory Effort Sensor is a device intended to be used in Sleep Disorders Testing for monitoring or recording abdominal (stomach) and thorax (chest) respiratory effort. It consists of a piezo sensor that converts breathing motion into an electrical output. The output goes into a passive low pass (15 Hz) electronic filter before the signal is then connected to a physiological recorder where the signal is amplified for monitoring or recording. This device is not intended for use as an Apnea Alarm.

The sensor is secured to the body using a one inch wide strap system of Velcro hook and elastic loop material. The sensor is usable with adults, children and babies since various length straps are available to suit the body size needs.

Executive Summary:

The Gereonics, Inc. Ultra-Piezo Respiratory Effort Sensor is a device intended to be used in Sleep Disorders Testing for monitoring or recording abdominal (stomach) and thorax (chest) respiratory effort. It consists of a piezo sensor that converts breathing motion into an electrical output. The output goes into a passive low pass (15 Hz) electronic filter before the signal is then connected to a physiological recorder where the signal is amplified for monitoring or recording. This device is not intended for use as an Apnea Alarm.

The sensor is secured to the body using a one inch wide strap system of Velcro hook and elastic loop material. See Figure 1-2. The sensor is usable with adults, children and babies since various length straps are available to suit the body size needs.

This device is very similar to a respiratory effort sensor manufactured and sold by Pro-Tech, Inc., Woodinville, Washington. The essential differences are the strap width and the location of the passive electronic filter.

Intended Use:

The Gereonics Ultra-Piezo Respiratory Sensor is intended for use in sleep disorders studies to measure respiratory effort for monitoring or recording on a physiological recording system.
