The summary describes a standard pulse oximeter sensor that measures SpO2 and pulse rate using LED and photodetector technology, without mentioning any AI or ML components or processes.
No
The device is used for monitoring SpO2 and pulse rate, which are diagnostic or monitoring functions, not therapeutic interventions.
No
Explanation: The device is indicated for monitoring SpO2 and pulse rate. While this data can be used to inform a diagnosis, the device itself is a measurement tool and does not provide a diagnosis.
No
The device description explicitly states that the device consists of a plug/connector, a cable, and a patient-contacting finger clip containing an LED and photodetector. These are physical hardware components, not solely software.
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 such as blood, urine, or tissue that have been taken from the human body to detect diseases or other conditions.
- Device Function: The Unimed Reusable Finger Clip SpO2 Sensors are used for continuous non-invasive monitoring of oxygen saturation and pulse rate directly on the patient's finger. This is a measurement taken in vivo (within the living body), not in vitro (in a test tube or laboratory setting).
- Lack of Sample Analysis: The device does not analyze a biological sample taken from the patient. It uses light transmission through the finger to determine the measurements.
Therefore, the description clearly indicates a device used for direct physiological monitoring on a living patient, which falls outside the scope of in vitro diagnostics.
N/A
Intended Use / Indications for Use
Unimed Reusable Finger Clip SpO2 Sensors are indicated for continuous non-invasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR) for adult patients weighing greater than 30 kg and pediatric patients weighing 10-50 kg. These devices are for prescription use only.

Device Description
The subject devices, Unimed Reusable Finger Clip SpO2 Sensors, are fully compatible reusable sensors for use with monitors that incorporate Masimo technology. These sensors are supplied non-sterile.
The subject sensors consist of a plug/connector (U403-125 and U103-125 with M8 sensor connector, and U403-254 and U103-254 with M10 sensor connector), a cable, and a patient-contacting (finger clip) where light-emitting diode (LED) and photodetector (PD) are located. The subject sensors share the same principle of operation as the predicate device for functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR) measurements. Also, the subject sensors have identical material composition and performance characteristics to the predicate device.
Compared with the predicate device (U403-125) in K142832, the subject devices have the following changes:
- Change in photodetector (light receiving part of the sensor) with the same spectral wavelength and shorter response time;
- Change in size or interface connector. Specifically, U103-125 is designed in smaller finger clip size for pediatric use, and U403-254 and U103-254 (smaller finger clip size as U103-125) are designed with a change in the interface connector for expanded compatible options with the same monitor.
