The description details standard pulse oximetry technology using light absorption and a microprocessor for calculation, with no mention of AI or ML algorithms.
No.
The device is for spot-checking oxygen saturation and pulse rate, which is a diagnostic function rather than a therapeutic one. It provides information but does not actively treat or alleviate a medical condition.
Yes
Explanation: The device is intended for "spot-checking of oxygen saturation and pulse rate" and calculates a "value for the oxygen saturation (SpO2)". This process of measuring a physiological parameter to gain information about the patient's health status is a diagnostic function.
No
The device description explicitly details hardware components such as a probe, electronic circuits, display, plastic enclosures, light emitting diodes, a light detector, and a microprocessor. It also mentions being powered by batteries.
Based on the provided information, 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 these samples outside of the body.
- Device Function: The description clearly states that the pulse oximeter measures oxygen saturation and pulse rate by shining light through the finger and detecting the transmitted light. This is a non-invasive measurement performed on the body, not on a sample taken from the body.
- Intended Use: The intended use is for "spot-checking of oxygen saturation and pulse rate for use with the finger of adult patients." This aligns with a physiological measurement device, not an IVD.
Therefore, the device described is a physiological monitoring device, specifically a pulse oximeter, and does not fit the definition of an In Vitro Diagnostic.
N/A
Intended Use / Indications for 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 healthcare environments. And it is not intended to be used under motion or low perfusion scenarios.

Device Description
The oximeter consists of probe, electronic circuits, and display and plastic enclosures. And one side of probe is designed to locate light emitting diodes and a light detector (called a photo-detector). Red and Infrared lights are shone through the tissues from one side of the probe to the other. Then parts of the light emitted absorbed by blood and tissues. The light absorbed by the blood varies with the oxygen saturation of haemoglobin. After that, the photo-detector detects the light volume transmitted through the tissues which depends on blood pulse, Hereafter, the microprocessor calculates a value for the oxygen saturation (SpO2). The subject device is a reusable device, and need to reprocess as suggested in the user manual after each use. And the device is intended to be used on the finger, and powered by 2*1.5V AAA battery.
