No
The document describes a standard pulse oximeter sensor and its equivalence to predicate devices, with no mention of AI or ML technology.
No
The device is a sensor for monitoring oxygen saturation and pulse rate, not for treating a condition.
Yes
The device is intended to "provide continuous, non-invasive monitoring of functional arterial oxygen saturation and pulse rate," which are measurements used to assess a patient's physiological state and contribute to diagnosis.
No
The device description explicitly states it is a "Pulse Oximeter Sensor" and describes "new Finger Sensor and Y-Sensor configurations," indicating a physical hardware component.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
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 DX Series Pulse Oximeter Sensors are described as providing "continuous, non-invasive monitoring of functional arterial oxygen saturation and pulse rate." This is done by placing the sensor on the patient's finger or toe and measuring light absorption through the skin.
- Lack of Sample Analysis: The device does not analyze any biological samples taken from the patient. It directly measures physiological parameters on the patient.
Therefore, the function and method of operation of this device clearly fall outside the scope of In Vitro Diagnostics.

Device Description
The DX Series Pulse Oximeter Sensors combine the operational characteristics of pulse oximetry sensors that have already received Substantially Equivalent determination from FDA (K993979 and K010451) into new Finger Sensor and Y-Sensor configurations that, like the predicate devices, share the same outward physical designs and fundamental scientific technology. The modification enables a sensor to be used with Dixtal's existing pulse oximeter monitor devices as currently listed, as well as to function with other pulse oximetry products. The modified sensors allow healthcare practitioners to more widely standardize pulse oximetry sensors and applicator accessories, and to minimize potential Human Factors issues that might result from using sensors and applicator accessories from multiple manufacturers.

Description of the Subject Device
The DX Series Pulse Oximeter Sensors combine the operational characteristics of pulse oximetry sensors that have already received Substantially Equivalent determination from FDA (K993979 and K010451) into new Finger Sensor and Y-Sensor configurations that, like the predicate devices, share the same outward

physical designs and fundamental scientific technology. The modification enables a sensor to be used with Dixtal's existing pulse oximeter monitor devices as currently listed, as well as to function with other pulse oximetry products. The modified sensors allow healthcare practitioners to more widely standardize pulse oximetry sensors and applicator accessories, and to minimize potential Human Factors issues that might result from using sensors and applicator accessories from multiple manufacturers.
Statement of Intended Use
The new DX Series Pulse Oximeter Sensors are reusable (multi-patient-use) sensors intended to provide continuous, non-invasive monitoring of functional arterial oxygen saturation and pulse rate in neonatal, infant, pediatric and adult patients, in environments where pulse oximetry monitors or modules in multiparameter systems are indicated for use, when in the judgment of a licensed medical practitioner/physician pulse oximetry is required.
Technological Characteristics
The new DX Series Sensors share the same outward physical designs, including materials and assembly processes, and the same fundamental scientific technology as the predicate devices (K993979 and K010451). The modification brings the designs of both listed predicates into a single sensor without using new or modified electro-optical components. The modified design operates as either one predicate device or the other-but not both-as dictated by the requirements of the pulse oximeter or oximeter/adapter cable combination to which it is attached. Bench testing and in vivo testing have confirmed equivalent performance.
A further discussion of the scientific technology can be found at Section 8 of the submission, while a more general discussion of the operational characteristics of pulse oximetry sensors is attached as Appendix 1.
Performance Data
Non-clinical data
Biocompatibility Testing: this evaluation was previously performed (2003 and 2006). We determined that repeat of the Biocompatibility Testing was unnecessary since we are using the identical materials as used in our current Finger and Y Sensors. The report documents testing compliant to ISO 10993-1:2003.
SpO-Sensor LED Temperature Test: Sensor testing was performed in an environmental chamber consistent with the requirements of ISO 9919:2005. The maximum temperature recorded was below 41 degrees C.
DX Sensor Bench Testing: Engineering bench studies were performed and documented using the intended mating device. We performed testing with Philips and Nellcor monitors comparing their performance to Dixtal monitors, all using the DX Series Sensors. Performance was determined to be equivalent.
DX Sensor Cleaning: Engineering performed a sensor cleaning evaluation to verify the cleaning agents recommended for use to clean and achieve low level disinfection of the Finger and Y Sensors are compatible with the sensor materials.
2
EMC Evaluation: The DX Series sensors with the extension cables were evaluated at the Philips Andover facility. Testing included Emissions and Immunity as well as ESD evaluation with results compliant to the requirements of the EMC related standards.
Hazards Analysis: Results of a Hazards Analysis for the DX Series SpO2 Finger and Y Sensor were documented and are included in this submission. We concluded that the devices are safe and effective for their intended use.
Clinical data
Controlled de-Sat Testing of DX Series Sensors: Testing was performed under IRB authorization from University of Southern California at San Francisco (Bickler, formerly Severinghaus) in compliance with ISO 9919:2005. The study included 24 healthy, non-smoker, subjects (with informed consent), half male and half female, ages 22-32. None were anemic and skin tone varied from light to dark. No adverse events or complications were noted. Based upon statistical standards (as noted in the report) clinical performance and accuracy of the DX Series Sensors is equivalent to the tested predicate devices.
Clinical Evaluation: Clinical Evaluation was initiated in a Brazilian Healthcare Facility (Irmandade da Santa Casa de Misericórdia de Porto Alegre) after receipt of written authorization from the Facility's (registered) IRB. The testing is focused upon Neonatal patients (and some Pediatric patients) to ensure we comply with the intent of Section 7.2 In Vivo testing for SpO2 accuracy for neonates, in the FDA Draft Guidance for Pulse Oximeters – Premarket Notification Submissions [510(k)s], dated July 19, 2007. No adverse events or complications have been noted.
Literature Review: A literature review was conducted and documented as part of our product evaluation. The report includes a discussion of motion and simulator testing however there were no significant issues identified that required further evaluation.
Conclusion:
In compliance with Guidance Documents, accepted Industry Standards, and Design Control requirements, the documented results of verification and validation testing, inter-device (Dixtal, Nellcor, Philips) comparison studies, and hypoxia studies, establish; the equivalent accuracy of DX Series Sensors manufactured for use with other pulse oximeter equipment, and that the Dixtal DX Series Sensors are Substantially Equivalent to the predicate devices.

Appendix 1 - Pulse Oximetry-Background
Pulse Oximeters to which these sensors are connected measures oxygen saturation and pulse rate with sensors that contain red and infrared light sources. Since oxygen saturated blood absorbs different amounts of light at each wavelength (red and infrared) as compared with unsaturated blood, the amount of light absorbed at each wavelength by the blood in each pulse can be used to calculate oxygen saturation.
The light energy from red (660 nm) and infrared (880nm or 940 nm) LEDs is beamed through a sample cella pulsating vascular bed, the patient's finger or toe for example. The remaining light energy not absorbed by the sample cell reaches a photodiode, on the opposing side of the signal received by the photodiode is split into its red and infrared components, sampled, software filtered and displayed as a numerical value for oxygen saturation and as a waveform, the Plethysmogram.
Functional oxygen saturation is defined as: percentage saturation given by the oxyhemoglobin concentration (cO2Hb) divided by the sum of the oxyhemoglobin concentration and the deoxyhemoglobin concentration (cHHb)
Fractional oxyhemoglobin FO2Hb: oxyhemoglobin concentration cO2Hb divided by the total hemoglobin concentration, ctHb where; cO2Hb is the concentration of oxyhemoglobin; ctHB is the concentration of total hemoglobin.
This is sometimes reported as a percentage (multiplying the fraction by 100).
Functional saturation represents the amount of oxyhemoglobin as a percentage of the hemoglobin that can be oxygenated. Dysfunctional hemoglobin (COHb and METHb) are not included in the measurement of functional saturation.

There are two vertical dashed lines labeled "Red 660nm" and "Infrared 940 nm". The curves show the relationship between these two variables.
Pulse Oximetry - Extinction Coefficients vs. wavelength (nm)
Pulse rate is calculated by measuring the time interval between the peaks of the infrared light waveform.
