Intended Use
Reprocessed Masimo Pulse Oximeter sensor is indicated for use in continuous noninvasive arterial oxygen saturation and pulse rate monitoring.
Device Description
In a clinical setting, a pulse oximeter sensor measures the oxygen saturation of arterial blood (SpO2). A pulse oximeter sensor is composed of a light emitting diode (LED) and a sensor that are placed on opposite sides of a patient's finger or foot. The LED contains a red light and an infrared light that are differentially absorbed by oxygenated hemoglobin. Based on the relative absorption of the two wavelengths that is determined by the sensor, the POX determines the relative amount of oxygenated and deoxygenated hemoglobin, which is calculated as SpO2. In order to make the SpO2 calculation independent of skin color, finger size, etc., the pulse oximeter sensor uses only the time varying light absorption component generated by the patient's pulse. The sensor also uses the period of pulsation to measure patient pulse rate. The pulse oximeter can estimate the amount of oxygen in the blood without having to draw a blood sample. The primary components of an oxygen transducer, or Pulse Oximeter (POX) Sensor, are light-emitting diodes (red and infrared LED) and a photo sensor. These components (with their wiring system) are embedded within a taping system designed for wrapping the POX Sensor around a patient's finger, foot, or hand so that the LED and photo sensor are directly opposite to each other. As the lights are emitted and received across a vascular bed, the rates of absorption at the two wavelengths vary depending upon the ratios of oxygenated hemoglobin within the blood. The proposed devices of this submission do not differ from the predicate device. The only difference is that the proposed devices will be exposed to vaporized hydrogen peroxide instead of ethylene oxide.
More Information

Not Found

No
The device description and performance studies focus on traditional signal processing and light absorption principles, with no mention of AI or ML algorithms.

No
The device is described as a sensor used for continuous noninvasive arterial oxygen saturation and pulse rate monitoring. It measures and calculates oxygen saturation (SpO2) and pulse rate, providing diagnostic information rather than directly treating or preventing a disease.

Yes.

The device measures oxygen saturation of arterial blood (SpO2) and pulse rate, which are physiological parameters used to assess a patient's health status. The "Intended Use / Indications for Use" section explicitly states "continuous noninvasive arterial oxygen saturation and pulse rate monitoring," which are diagnostic functions.

No

The device description explicitly details hardware components (LED, sensor, wiring system, taping system) and their physical interaction with the patient's body to measure physiological parameters. The submission focuses on the reprocessing method of these physical sensors, not on software functionality.

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.
  • Device Function: The description clearly states that the pulse oximeter sensor measures oxygen saturation and pulse rate noninvasively by placing the sensor on the patient's finger or foot. It does not require a sample to be taken from the body.
  • Mechanism of Action: The device works by emitting and detecting light through the patient's tissue, analyzing the absorption characteristics of oxygenated and deoxygenated hemoglobin within the blood vessels. This is an external measurement, not an analysis of a biological sample.

Therefore, while it provides diagnostic information about the patient's physiological state, it does so through an in vivo (within the living body) measurement rather than an in vitro (in glass/outside the body) analysis of a sample.

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

Non-Clinical and/or Clinical Tests Summary & Conclusions:
To support the substantial equivalence of product performance after by vaporized hydrogen peroxide to that of the predicate devices, non-clinical bench simulation testing was conducted using a stand-in device allows for SpO2 sensor verification by passing the light source of the pulse oximeter sensor (LED) thru one side of the stand-in with the signal transmission measured by the photocell (photo-detector) of the pulse oximeter sensor on the opposing side of the stand-in.
A functional pulse oximeter sensor when connected to a pulse oximeter console will have the ability to monitor SpO2 and Pulse Rate. Bench and laboratory testing was conducted to determine whether a pulse oximeter sensor is functional and is assessed by performing continuity and sensitivity testing. This included the following tests:

  • Continuity testing to verify there are no open circuits and the current along the path of a circuit is continuous
  • Sensitivity testing to detect the signal transmission between the photodiode and the LED (light emitting diode)

Performance testing , incorporated by reference K081238, also included the following which are not altered by the use of vaporized hydrogen peroxide.

Clinical Testing:
Stryker Sustainability Solutions performed the clinical validation testing of the SpO2 performance under no motion on healthy, adult volunteers in the range of 70% to 100%. The ARMS for SpO2 under no motion was found to be 1.48% and 1.72% for woven and non-woven tape over the range of 70-100%.
The results of the non-clinical and clinical testing demonstrate that all requirements and performance specifications were satisfied and support the subject device is substantially equivalent to its predicate.

Intended Use/Indications for Use

Reprocessed Masimo Pulse Oximeter sensor is indicated for use in continuous noninvasive arterial oxygen saturation and pulse rate monitoring.

Indications for Use Comparison

The indications for use are the same as the predicate device.

Technological Comparison

The design of the reprocessed device is the same as the predicate device. There are no changes to the claims, clinical applications, patient population, or performance specifications for use does not change from the predicate device (K081238). The same standard mechanical design and equivalent materials are utilized. There are no changes to the claims, clinical applications, patient population, or performance specifications.

The subject device, LNCS Pulse Oximeter Sensors and the predicate device, have the following key similarities:

  • intended use;
  • principle of operation;
  • form factor and components;
  • measurement application sites;
  • performance specifications;
  • environmental and mechanical specifications- Both devices have the same indicated populations;

Principle of Operation

The principle of operation of pulse oximetry is based upon the fundamental principle that hemoglobin bound to oxygen (oxyhemoglobin) and hemoglobin unbound to oxygen (deoxyhemoglobin) vary in the absorption of different wavelengths of the light and the absorptions can be used to estimate SpO2 and pulse rate. The mechanism by which this process occurs is the use of red and infrared wavelengths of light delivered by an emitter and the signal from the light absorption of oxygenated blood and deoxygenated blood to determine functional oxygen saturation of hemoglobin (SpO2).

Mechanism of Action for Achieving the Intended Effect

The Reprocessed Pulse Oximeter Sensor provides the intended effect equivalent to the previously cleared pulse oximeter sensor in that it utilizes an optical sensor that is applied to the patient's finger or toe through which light is transmitted to the photodetector that detects the signal transmissionis processed by the Pulse Oximeter to provide SpO2 and pulse rate.The principles of operation are still based upon the use of red and infrared wavelengths of light provided by an emitter and the detection of the signal from the light absorption of oxygenated blood and deoxygenated blood to provide functional oxygen saturation of hemoglobin (SpO2).

A functional pulse oximeter sensor when connected to a pulse oximeter console will have the ability to monitor SpO2 and Pulse Rate. Bench and laboratory testing was conducted to determine whether a pulse oximeter sensor is functional and is assessed by performing continuity and sensitivity testing. This included the following tests:

  • Continuity testing to verify there are no open circuits and the current along the path of a circuit is continuous
  • Sensitivity testing to detect the signal transmission between the photodiode and the LED (light emitting diode)
