Intended Use

The Thermotocus series 0800, 01500 and 0700 are infrared thermometers intended for the intermittent measurement of human body temperature of people of all ages

Device Description

Thermofocus devices belonging to the 0800, 0900, 01500, 0700 series are hand-held and battery-operated, taking skin temperature mainly in the middle of the forehead. In case of difficult to take the temperature on this area it is also possible to take the temperature on the navel or under the armpit. The Thermofocus devices use the principle of surveying the natural emission of infrared thermal radiation from all objects, including the human body. Thanks to an exclusive optic aiming system, the peculiarity of Thermofocus thermometers is to take the temperature at distance, without any contact with the patient.

AI/ML Overview

The provided document is a 510(k) summary for the Tecnimed Thermofocus series of infrared thermometers. It describes the device, its intended use, and provides a summary of performance testing.

Here's an analysis of the acceptance criteria and study information contained within:

1. Table of Acceptance Criteria and Reported Device Performance

Performance TestAcceptance Criteria (Implied)Reported Device Performance

°F vs °C testsPassPass
Error messages testsPassPass

Clinical PerformanceSubstantial equivalence to predicate (Sensortouch)Substantial equivalence demonstrated

Note: The document states "Both devices meet the ASTM E1965-98 Standard for Infrared Thermometer for Intermittent Determination of Patient Temperature, as far as this standard applies to them." This ASTM standard would contain specific quantitative acceptance criteria for parameters like accuracy and repeatability, but these specific values are not explicitly detailed in this 510(k) summary.

2. Sample Size Used for the Test Set and Data Provenance

  • Sample Size for Test Set: The document states that "The numerous tests conducted in our laboratories and also in hospital and clinics, on several subjects..." but does not specify the exact sample size for subjects or cases used in the clinical performance testing.
  • Data Provenance: The tests were conducted in "our laboratories" and "hospital and clinics." This indicates prospective data collection through internal testing and clinical sites. The country of origin for Tecnimed srl is Italy.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This information is not provided in the document. The clinical performance testing focused on demonstrating "substantial equivalence between Thermofocus and the predicate Sensortouch," implying a comparison to the predicate device's readings rather than a separate expert-established ground truth.

4. Adjudication Method for the Test Set

This information is not provided in the document.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance

This section is not applicable. The device is an infrared thermometer, not an AI-powered diagnostic tool requiring human reader interpretation or improvement.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done

The device is a standalone thermometer (algorithm-only in its functional sense, as it autonomously measures and displays temperature). The document implicitly describes standalone performance testing as part of the "Summary of non-clinical Performance Testing" (e.g., accuracy, repeatability) and the comparative clinical testing against the predicate.

7. The Type of Ground Truth Used

For the clinical performance testing, the ground truth was based on comparison to a legally marketed predicate device (TemporalScanner thermometer, formerly known as SensorTouch). The study aimed to demonstrate "substantial equivalence" to this predicate. For the non-clinical performance tests (accuracy, repeatability, etc.), the ground truth would typically be established against calibrated reference standards or methods as defined by the ASTM E1965-98 standard, though not explicitly stated here.

8. The Sample Size for the Training Set

This information is not applicable/not provided. The Thermofocus is a physical electronic device that measures infrared radiation; it does not explicitly use a "training set" in the machine learning sense to develop an algorithm. Its "algorithm" is likely embedded mathematical adjustments based on physics and sensor readings, not learned from a dataset.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable/not provided for the reasons stated above (no training set in the machine learning context).

Summary of clinical Performance Testing: The numerous tests conducted in our laboratories and also in hospital and clinics, on several subjects and at several ambient temperatures, demonstrate a substantial equivalence between Thermofocus and the predicate Sensortouch. Conclusion: Since performance tests are similar, and both thermometers have the same basic characteristics and conform to the same standard, we can conclude that Thermofocus devices belonging to the 0800, 0900, 01500, 0700 series are substantially equivalent to the predicate Sensortouch.
