The input text does not contain any Reference Devices (K/DEN number). It only lists a Predicate Device.
No
The description focuses on standard pulse oximetry technology using light absorption and a microcontroller. There is no mention of AI or ML algorithms for data processing or interpretation. The modifications are related to connectivity and power source, not core signal processing.
No.
The device is indicated for measuring and displaying oxygen saturation and pulse rate, which are diagnostic functions, not therapeutic.
Yes
Explanation: The device measures and displays functional oxygen saturation of arterial hemoglobin (%SpO2) and pulse rate, which are used to assess a patient's physiological state. This measurement of physiological parameters for assessment constitutes a diagnostic function.
No
The device description explicitly states it is a "digit pulse oximeter" that contains "Light emitting diodes (LEDs)" and a "photo detector," along with "associated electronics and the microcontroller." These are hardware components, making it a physical medical device, not software-only.
Based on the provided text, the Nonin® Model 3231 Finger Pulse Oximeter is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body. This device measures physiological parameters (oxygen saturation and pulse rate) directly on the patient's digit by passing light through the tissue. It does not analyze blood, urine, or any other sample taken from the body.
- The description focuses on non-invasive measurement. The device description clearly states it measures the absorption of light passing through perfused tissue.
- The intended use is for measuring and displaying physiological parameters. The intended use is to measure and display %SpO2 and pulse rate, not to analyze a sample for diagnostic purposes.
Therefore, the Nonin® Model 3231 Finger Pulse Oximeter is a non-invasive medical device used for monitoring physiological signs, not an IVD.

Device Description
Model 3231 Pulse oximeter is a small, lightweight, portable, digit pulse oximeter that displays numerical values for functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate by measuring the absorption of red and infrared (IR) light passing through perfused tissue. Changes in the absorption caused by the pulsation of blood in the vascular bed are used to determine oxygen saturation and pulse rate. Light emitting diodes (LEDs) are contained within the device along with the photo detector, which is on the opposite side of the probe from the LEDs. The SpO2 and pulse rate are displayed on the LCD display contained within the device. A color LCD provides a visual indication of the pulse signal, while blinking at the corresponding pulse rate. The display will indicate if there is poor pulse quality that may affect the readings. All associated electronics and the microcontroller are within the sensor, which is activated by placing on a patient's digit. This simple operation activates the internal circuitry automatically upon application. The device is intended for spot-checking adult and pediatric patients who are well or poorly perfused.
The modification of the Model 3230 to the Model 3231, include the removal of Bluetooth LE 4.0 and the addition USB 2.0 for serial communication. This modification includes moving from batteries to the USB 2.0 to power the Model 3231. The oximeter circuitry, software and electro optical elements of the Model 3231 are identical to the Model 3230. There are no technological characteristic changes to the device that affect the measurement or display of SpO2 or pulse rate to the user.

Dear Mr. Pedersen:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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 Federal Register.
5
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. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Division of Small Manufacturers, International and Consumer Assistance at its tollfree number (800) 638-2041 or (301) 796-7100 or at its Internet address
http://www.fda.gov/MedicalDevices/ResourcesforYou/Industry/default.htm. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to
http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.
You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 796-7100 or at its Internet address http://www.fda.gov/MedicalDevices/ResourcesforYou/Industry/default.htm.
