No
The summary describes a sensor that measures CO2 concentration, a standard physiological measurement. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices. The performance studies focus on standard device testing (electromagnetic, environmental, safety, performance) rather than validation of an algorithm.

No
The device measures CO2 concentration to aid in determining ventilatory status but does not directly treat or cure any condition. It is a diagnostic aid, not a therapeutic device.

Yes

The device measures carbon dioxide concentration to aid in determining the patient's ventilatory status, which is a diagnostic purpose, even though it states it is "not intended as the sole basis for medical diagnosis."

No

The device description explicitly refers to a "CO2 Sensor Kit, model number TG-901T," which implies the presence of hardware components (the sensor itself) in addition to any potential software. The performance studies also mention testing procedures for the device, further suggesting a physical product.

Based on the provided information, the Nihon Kohden TG-901T CO2 Sensor is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVD definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
  • Device function: The TG-901T CO2 Sensor measures the concentration of carbon dioxide in a gas mixture, specifically during patient expiration. This is a measurement of a gas exhaled by the patient, not a specimen taken from the body.
  • Intended Use: The intended use clearly states it measures CO2 in a "gas mixture" to aid in determining "ventilatory status." This aligns with monitoring respiratory function, not analyzing bodily fluids or tissues.

Therefore, the TG-901T CO2 Sensor falls under the category of a physiological monitoring device rather than an IVD.

SECTION 2 - 510(K) SUMMARY

Name and Address of Applicant Nihon Kohden America, Inc. Attn: Regulatory Affairs 2601 Campus Drive Irvine, California 92612-1601

Nihon Kohden Corporation 31-4 Nishiochiai, 1-Chome Shinjuku-ku, Tokyo, 161 Japan

The TG-901T CQ2 Sensor Kit is classified as Class II by the Division of Anesthesiology Devices and the Anesthesiology Device Classification Panel under 21 CFR Part 868.1400 "Analyzer, Gas, Carbon dioxide, Gaseous-phase" as per part 73 CCK.

Common names for the TG-901T CO2 Sensor Kit include CO2 Analyzer and CO2 Indicator.

The predicate device is the OLG-1100A PocketCap CO2 Monitor per 510(k) # K964305, commercial distribution certification dated February 19, 1997.

The Nihon Kohden CO2 Sensor Kit, model number TG-901T, is intended for medical purposes to measure the concentration of carbon dioxide in a gas mixture to aid in determining the patient's ventilatory status. The device is intended as an indicator of patient carbon dioxide concentration during expiration and is not intended as the sole basis for medical diagnosis. This device is intended for use with patients of ages three (3) years and older. This device is not recommended for patients with low tidal volume such as patients younger than three (3) years of age or weighing less 22 pounds or patients with a respiration rate greater than or equal to 60 breaths per minute.

To date, no performance standards or special controls are known or established for this device as required by Section 514 of the Food, Drug and Cosmetic Act and implemented by 21 CFR Part 861.

The TG-901T is not intended to be sterile.

The TG-901T was subject to electromagnetic, environmental, safety and performance testing procedures. These tests verified the operation of the device.

Therefore, based on the above, Nihon Kohden believes that the TG-901T CO2 Sensor Kit is substantially equivalent to the OLG-1100A Pocket CO2 Monitor.
