No
The device description details a standard pulse oximetry mechanism based on light absorption and an algorithm to calculate the ratio. There is no mention of AI or ML in the description, performance studies, or key metrics.
No.
The device is indicated for continuous non-invasive monitoring of functional oxygen saturation and pulse rate, which is a diagnostic function, not a therapeutic one.
Yes
The device is a diagnostic device because it monitors functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR), which are physiological parameters used to assess a patient's health status. The information gathered by the device aids in the diagnosis and management of conditions related to oxygen saturation and heart rate.
No
The device description clearly outlines hardware components (LEDs, photodiode, adapter cable, sensor probe) and their physical interaction with the patient to acquire data. It is an accessory to a patient monitor, which is also a hardware device.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens from the human body. The description clearly states that the Caremed Disposable SpO2 Sensors are used for "continuous non-invasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR)" by attaching a probe to the patient's finger. This is a direct measurement on the patient, not an analysis of a specimen taken from the patient.
- The mechanism of action involves light absorption through tissue. The device measures light absorption characteristics of hemoglobin in the blood vessels of the finger. This is a physical measurement taken in vivo, not a chemical or biological analysis of a sample in vitro (outside the body).
Therefore, the Caremed Disposable SpO2 Sensors are considered a medical device used for patient monitoring, but they do not fit the definition of an In Vitro Diagnostic.

Device Description
The proposed device, Disposable SpO2 Sensors are accessories to the patient monitors, which are intended for continuous non-invasive monitoring of functional arterial oxygen saturation and pulse rate. The compatible patient monitor is Nihon Kohden BSM-5135A. The sensor shall be connected to its corresponding monitor through Caremed adapter cable model SZ30-36. Oxygenation of blood is measured by detecting the infrared and red-light absorption characteristics of deoxygenated hemoglobin and oxygenated hemoglobin, which consists of a probe attached to the patient's finger. The sensor is connected to a data acquisition system which is used to calculate and display oxygen saturation levels and heart rate conditions. Each sensor has two LEDs, emitting both red and infrared light, and a photodiode. Red and infrared light lit alternately according to certain sequence, when the fingertips of capillary repeatedly with the heart pumps blood congestion, light emitting diode after blood vessels and projected onto a photodiode, photodiode can be induced to change with pulse light intensity, the electrical signals in the form of change. Then the received signal is forwarded to the corresponding oximeter that amplifies the signal and an algorithm that calculates the ratio. By measuring the wave crest of the pulse wave and the absorbance of the trough, SpO2 is calculated to obtain the correct oxygen saturation value. The saturation value is determined by the percentage ratio of the oxygenated hemoglobin (HbO2) to the total amount of hemoglobin (Hb).

Dear Kevin Wang:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.
