Intended Use
The Nihon Kohden TG-920P CO2 Sensor Kit, is intended for medical purposes to measure the concentration of carbon dioxide in a gas mixture to aid in determining the patient's ventilatory (end tidal CO>) status. As interpreted by the physician for medical diagnosis, this device is intended as an indicator of patient carbon dioxide concentration during expiration.
Device Description
The TG-920P CO2 Sensor Kit is intended for medical purposes to measure the concentration of carbon dioxide in a gas mixture to aid in determining the patient's ventilatory (end tidal CO>) status. The device measuring technique is through absorption of infrared radiation. The mouth/nose piece airway adapter, is a Single-Patient-Use and hence, disposable. The device is intended as an indicator of patient carbon dioxide concentration during expiration, for non-intubated patients.

No
The description focuses on infrared absorption for CO2 measurement and does not mention AI or ML.

No
The device measures a physiological parameter (CO2 concentration) to aid in diagnosis, but it does not directly treat or alleviate a medical condition.

Yes

The "Intended Use / Indications for Use" section explicitly states that the device is "As interpreted by the physician for medical diagnosis".

No

The device description explicitly mentions a "CO2 Sensor Kit" and a "mouth/nose piece airway adapter," which are physical hardware components used to measure carbon dioxide. The description of performance studies also mentions "electromagnetic, environmental, safety and performance testing procedures," which are typical for hardware devices.

Based on the provided text, the Nihon Kohden TG-920P CO2 Sensor Kit is not an IVD (In Vitro Diagnostic).

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 TG-920P CO2 Sensor Kit measures the concentration of carbon dioxide in a gas mixture (specifically, the patient's expired breath). This is a measurement of a physiological process happening in vivo (within the living body), not a test performed on a sample in vitro (outside the living body).
  • Intended Use: The intended use is to "measure the concentration of carbon dioxide in a gas mixture to aid in determining the patient's ventilatory (end tidal CO>) status." This directly relates to monitoring a physiological function of the patient.

Therefore, the device falls under the category of a physiological monitoring device rather than an in vitro diagnostic device.

SECTION 2 - 510(K) SUMMARY

OCT 1-5 2004

Name and Address of Applicant: Nihon Kohden America, Inc. 90 Icon St. Foothill Ranch, California 92610 Attn: Regulatory Affairs, Ms. Serrah Namini

Name and address of Manufacturer: Nihon Kohden Corporation 1-31-4 Nishiochiai, Shinjuku-ku, Tokyo, 161-8560 Japan

The TG-920P CO2 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-920P CO2 Sensor Kit include CO2 Analyzer and CO2 Indicator.

The predicate marketed device is the Nihon Kohden TG-901T CO2 Sensor Kit as per 510(k): K990063, commercial distribution certification dated June 1999.

The Nihon Kohden CO2 Sensor Kit, model number TG-920P, is intended for medical purposes to measure the concentration of carbon dioxide in a gas mixture to aid in determining the patient's ventilatory (end tidal CO>) status. The device measuring technique is through absorption of infrared radiation. The mouth/nose piece airway adapter, is a Single-Patient-Use and hence, disposable.

The device is intended as an indicator of patient carbon dioxide concentration during expiration, for non-intubated patients. 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 than 22 pounds or patients with a respiration rate greater than or equal to 150 breaths per minute.

The device performance and specifications are consistent with all requirements for this device type. To date, no performance standards or special controls are known or established for this type of device. The device was subject to electromagnetic, environmental, safety and performance testing procedures. These tests verified the safety and efficacy of the device under intended operation for this device. The device is not sterile.

Therefore, based on the above, Nihon Kohden believes that the TG-920P CO2 Sensor Kit is substantially equivalent to Nihon Kohden's TG-901T CO2 Sensor Kit.
