Intended Use
The Fingertip Pulse Oximeter is a non-invasive device intended for spot checking of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR). This portable device is indicated for use in adult patients in clinical institution and home environments.
Device Description
The Fingertip Pulse Oximeter is intended for use in measuring and displaying functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR). The Fingertip Pulse Oximeter works by applying a sensor to a pulsating arteriolar vascular bed. The sensor contains a dual light source and photo detector. The one wavelength of light source is 660 nm, which is red light; the other is 905 nm, which is Infrared light. Skin, bone, tissue, and venous vessels normally absorb a constant amount of light over time. The photodetector in finger sensor collects and converts the light into electronic signal which is proportional to the light intensity. The arteriolar bed normally pulsates and absorbs variable amounts of light during systole and diastole, as blood volume increases and decreases. The ratio of light absorbed at systole is translated into an oxygen saturation measurement. This measurement is referred to as SpO2. The Pulse Oximeter is powered by 2 AAA alkaline batteries. The device mainly composed of PCB board, On/Off button, OLED or LED or LED screen, battery compartment, and plastic shell. The device is a spot-check pulse oximeter and does not include alarms. The device is not intended for life-supporting or life-sustaining.
More Information

No
The device description and performance studies focus on standard pulse oximetry technology and do not mention any AI or ML components or capabilities.

No

Explanation: The device is intended for spot checking of functional oxygen saturation and pulse rate, which are diagnostic measurements, not therapeutic interventions. The "Intended Use" section clearly states it is a "non-invasive device intended for spot checking."

Yes

The device is intended for "spot checking of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR)," which are measurements used to assess a patient's physiological state and can inform a diagnosis.

No

The device description explicitly lists hardware components such as a PCB board, On/Off button, screen, battery compartment, and plastic shell, indicating it is a physical device, not software-only.

No, this device 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. They are used to examine specimens outside of the body.
  • Fingertip Pulse Oximeter Function: The description clearly states that the Fingertip Pulse Oximeter is a non-invasive device that measures oxygen saturation and pulse rate by applying a sensor to the finger. It works by analyzing light absorption through the skin and tissue, not by testing a sample taken from the body.

The device is a non-invasive medical device used for physiological monitoring.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Clinical studies were conducted to verify the accuracy of proposed device. The clinical studies were conducted per following standards:

  • ISO 80601-2-61: 2017 Medical Electrical Equipment - Part 2-61: Particular Requirements for Basic Safety and Essential Performance of Pulse Oximeter Equipment.
  • Pulse Oximeters-Premarket Notification Submissions: Guidance for Industry and Food and Drug Administration Staff

Clinical testing has been performed under an approved protocol with subject informed consent. Clinical hypoxia test results were obtained in human adult volunteers to validate the accuracy of Pulse Oximeter versus arterial oxygen saturation (SaO2) as determined by co-oximetry. Clinical test results support device accuracy claims for the specified saturation range.

Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

SpO2 Accuracy: 70% ~ 100%, Arms ± 3%.
