Indications for Use
The TL-101T, TL-120T and TL-121T SpO2 Probes are intended for use with Nihon Kohlen patient monitoring devices to measure the blood oxygen saturation of a patient based upon the amount of reflected or scattered light. The TL-101T is a finger probe intended for use on adult patients heavier than 20 kg. The TL-120T is a multi-site probe intended for use on adults and infants heavier than 3 kg. The TL-121T is a foot probe intended for use on infants and neonates lighter than 3 kg.
Device Story
SpO2 probes (TL-101T, TL-120T, TL-121T) function as accessories to Nihon Kohden patient monitors; measure blood oxygen saturation via reflected/scattered light. TL-101T (finger probe) for adults >20 kg; TL-120T (multi-site) for adults/infants >3 kg; TL-121T (foot probe) for infants/neonates <3 kg. Used in clinical settings by healthcare providers; output displayed on compatible Nihon Kohden monitors (AL-800PA, BSM-2101A/2102A, ZB-831PA). Data informs clinical decision-making regarding patient oxygenation status.
Clinical Evidence
Bench testing only. Biocompatibility testing performed per ISO 10993: primary skin irritation (Cumulative Irritation Index 0.00), sensitization (no delayed dermal contact sensitization), and cytotoxicity (no cell lysis/toxicity > USP grade 2). Safety and performance testing verified device operation within specifications.
Technological Characteristics
SpO2 probes utilizing light reflection/scattering principle. Non-sterile. Biocompatibility verified per ISO 10993. Connectivity: compatible with Nihon Kohden patient monitoring modules/transmitters. Form factors: finger probe (TL-101T), multi-site probe (TL-120T), foot probe (TL-121T).
Indications for Use
Indicated for blood oxygen saturation measurement. TL-101T: adults >20 kg. TL-120T: adults and infants >3 kg. TL-121T: infants and neonates <3 kg.
Regulatory Classification
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.

SECTION 2 - 510(K) SUMMARY
Name and Address of Applicant Nihon Kohden America, Inc. Attn: Requiatory Affairs 2601 Campus Drive Irvine, California 92612-1601 (714) 250-3959
The TL-101T. TL-120T and TL-121T SpO2 Probes are accessories for use with Nihon Kohden patient monitoring devices and are not individually classified. Common names for the devices include SpO2 probe, SpO2 sensor, pulse oximeter probe, pulse oximeter sensor, probe and sensor.
The TL-101T, TL-120T and TL-121T SpO2 Probes are new optional accessories for use with the following Nihon Kohden devices: AL-800PA SpO2 Module per 510(k) #K884536, dated February 6, 1989; BSM-2101A and BSM-2102A Patent Monitors, per 510(k) #K914092, dated May 28, 1992; and ZB-831PA Telemetry Transmitter, per 510(k) #K946175, dated November 22, 1995
The predicate marketed devices are the Nihon Kohden TL-101S. TL-120S and TL-121S SpO2 Probes. which are accessories for the AL-800PA SpO2 Module, per 510(k) #K884536, dated February 6, 1989, used with the BSM-8800A Bedside Monitor per 510(k) #K920154, dated December 18, 1992.
Nihon Kohden's TL-101T, TL-120T and TL-121T SpO2 Probes are used with Nihon Kohden patient monitoning devices to measure the blood oxygen saturation of a patient based upon the amount of reflected or scattered light.
The TL-101T is a finger probe intended for use on adult patients heavier than 20 kg. The TL-120T is a multi-site probe intended for use on adults and infants heavier than 3 kg. The TL-121T is a foot probe intended for use on infants and neonates lighter than 3 kg.
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 TL-101T, TL-120T and TL-121T devices are not intended to be sterile.
Biocompatibility testing was performed in accordance with the guidelines of the International Organization for Standardization Part 10: Tests for Irritation. Primary skin irrilation studies calculated the Cumulative Irritation Index of 0.00.with no irritation observed on the rabbits. Sensitization studies showed no evidence of delayed dermal contact sensitization in the guinea pig. Cytotoxicity studies showed no evidence of causing cell lysis or toxicity greater than a USP grade of 2 (mild reactivity). The test articles passed these ISO studies.
The TL-101T, TL-120T and TL-121T SpO2 Probes were subjected to safety and performance testing procedures. These tests ventied that the device performed within specifications.
Therefore based on the above, Nihon Kohden believes that the TL-101T, TL-120T and TL-121T SpO2 Probes are substantially equivalent to the TL-101S, TL-120S and TL-121S SpO2 Probes.
