NC Thermometer (Gen 3) ISO 80601-2-56 Validation

Natural Cycles105 enrolled

Overview

The purpose of this clinical validation is to evaluate the the clinical bias, the limits of agreement, and the clinical repeatability of measuring oral temperature using a new thermometer, NC° Thermometer (Gen 3), compared to a reference clinical thermometer.

The purpose of this clinical study is to validate the clinical accuracy of the NC° Thermometer (Gen 3) according to the requirements of ISO 80601-2-56:2017. The NC° Thermometer (Gen 3) (the device under study (DUT)) is a predictive thermometer that operates in adjusted mode. The Welch Allyn oral thermometer (Welch Allyn Spot Vital Signs 420 SureTemp temperature module, Welch Allyn, San Diego, CA) with a measurement accuracy of ± 0.1 °C in monitor mode will be used the reference clinical thermometer (RCT). During the clinical study, subjects will be asked to perform three consecutive oral measurements with the DUT, and one oral measurement with the RCT.

Outcomes

Primary Outcomes

Clinical Bias

Clinical bias is the mean difference between the output temperatures of the NC° Thermometer (Gen 3) (DUT) and the reference clinical thermometer (RCT) for a specific reference body site (the mouth) when measured from a selected group of subjects. The clinical bias of the DUT defines closeness between the DUT output temperature and that of the RCT.

Time frame: Up to 1 hour

Limits of agreement

Dispersion of output temperatures around the clinical bias can be estimated by the standard deviation of the temperature differences between the DUT and the RCT as measured from multiple subjects.

Time frame: Up to 1 hour

Clinical repeatability

Clinical repeatability (sometimes called the perceived accuracy) is a measure of the consistency of repeated measurements with identical operating conditions when temperatures are taken within short time intervals from the same measuring site of the same subject by the same operator with the same intermittent clinical thermometer. Clinical repeatability is a pooled standard deviation of triplicate measurements over the population of subjects.

Time frame: Up to 1 hour
