Device consists of internal optical components and flexible circuit encapsulated in synthetic, latex-free rubber overmold. Sensor plug contains memory chip storing sensor-specific data (e.g., model, calibration) for oximeter compatibility. Device connects to Nellcor and other monitors using R-Cal or OxiMAX (DigiCal) technology. Operates by transmitting light through tissue to measure arterial oxygen saturation and pulse rate. Used in clinical settings by healthcare providers to monitor patient oxygenation status; output displayed on compatible oximeter monitor to assist in clinical decision-making and patient management. ## Clinical Evidence Human oxygenation evaluations conducted to confirm accuracy and precision specifications. Bench testing performed for conformance with ISO 9919:2005 requirements. ## Technological Characteristics Reusable digit sensor; synthetic, latex-free rubber overmold; internal optical components and flexible circuit. Memory chip in plug for sensor identification/calibration. Compatible with Nellcor R-Cal or OxiMAX (DigiCal) technology. Designed to meet ISO 9919:2005 safety and performance standards. ## Regulatory Identification An oximeter is a device used to transmit radiation at a known wavelength(s) through blood and to measure the blood oxygen saturation based on the amount of reflected or scattered radiation. It may be used alone or in conjunction with a fiberoptic oximeter catheter. ## Predicate Devices - Nellcor Puritan Bennett, Inc., OxiMax Pulse Oximetry System with N-595 Pulse Oximeter and OxiMax Sensors ([K012891](/device/K012891.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The DuraMax sensor consists of an internal frame containing the optical components and flexible circuit encapsulated in a synthetic, latex-free rubber overmold. The DuraMax sensor plug contains a memory chip carrying information about the sensor which the oximeter needs for correct operation, including Advanced Signal Evaluation, Intention and data set revision, and sensor model. The DuraMax sensor is compatible with Nellcor and other monitors incorporating either Nellcor R-Cal or OxiMAX (DigiCal) oximetry technology. {1}------------------------------------------------ ## INTENDED USE The DuraMax® reusable digit sensor is intended for use with patients weighing 40 kg or more when noninvasive arterial oxygen saturation and pulse rate monitoring are required. # SUMMARY OF TECHNOLOGICAL CHARACTERISTICS OF THE DEVICE COMPARED TO THE PREDICATE DEVICE The Nellcor DuraMax sensor has the same technological characteristics as the Nellcor DS-100A reusable sensor. The sensor uses the same optical components as the DS-100A. The differences relate to dimensions, one-piece external design, materials of construction, and labeling. #### DETERMINATION OF SUBSTANTIAL SUPPORT TESTS PERFORMED TO EQUIVALENCE Human and bench tests were performed to support the determination of substantial equivalence. Human oxygenation evaluations were conducted to confirm conformance to accuracy and precision specifications. The DuraMax sensor has been designed and tested for conformance with the applicable requirements of ISO 9919:2005, "Medical equipment - Particular requirements for the basic safety and essential performance of pulse oximeter equipment for medical use". When properly connected to an oximeter that is also compliant with this standard, the resulting system will comply with the standard. ### CONCLUSIONS The technological characteristics of the DuraMax sensor and the results of testing do not raise new questions of safety or effectiveness when compared to the legally marketed predicate device. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image is a black and white logo for the U.S. Department of Health and Human Services.

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Eederal Register. {3}------------------------------------------------ ### Page 2 - Mr. Bonds Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
