Intended Use
The pulse oximeter is a reusable device and intended for spot-checking of oxygen saturation and pulse rate for use with the finger of adult patients in home and healthcare environments. And it is not intended to be used under motion or low perfusion scenarios.
Device Description
The Pulse Oximeter is a battery powered device in measuring and displaying functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR). The 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 m, 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. The ratio of light absorbed at systole and diastole is translated into an oxygen saturation measurement. This measurement is referred to as SpO2. The device mainly composed of PCB board, On/Off button, mode button, OLED&LED screen, battery compartment, Bluetooth® module and plastic shell. There are five models AOJ-70A, AOJ-70C, AOJ-70E. Only AOJ-70E. Only AOJ-70D have wireless connection function via Bluetooth®. The device is a spot-check pulse oximeter and does not intended for life-supporting or life-sustaining.
More Information

No
The description details a standard pulse oximetry mechanism based on light absorption and ratio calculation, with no mention of AI or ML algorithms for data processing or interpretation. The performance study focuses on standard accuracy metrics (ARMS) against CO-Oximetry, not on AI/ML model performance.

No
The device is described as a pulse oximeter intended for "spot-checking of oxygen saturation and pulse rate" and is "not intended for life-supporting or life-sustaining." It measures physiological parameters but does not provide therapy or treatment.

Yes
The device is a pulse oximeter intended for spot-checking of oxygen saturation and pulse rate, which are physiological parameters used to assess a patient's condition. While not for diagnosis of a specific disease, it provides data that aids in the diagnostic process or monitoring of health status, classifying it as a diagnostic device in a broad sense.

No

The device description explicitly details hardware components such as a PCB board, buttons, screen, battery compartment, Bluetooth module, and plastic shell, indicating it is a physical device with embedded software, not a software-only medical device.

Based on the provided text, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs analyze samples taken from the body (like blood, urine, tissue). The description clearly states the pulse oximeter works by applying a sensor to the finger to measure oxygen saturation and pulse rate non-invasively. It does not involve collecting or analyzing a sample from the patient.
  • The mechanism of action is based on light absorption through the skin and tissue. This is a physical measurement of physiological parameters, not a chemical or biological analysis of a sample.

The device is a medical device used for monitoring physiological signs, but it does not fit the definition of an In Vitro Diagnostic.
