The document describes a standard infrared thermometer that measures temperature and transmits data. There is no mention of AI/ML algorithms for data processing, interpretation, or decision-making.
No
The device is described as an infrared thermometer intended for "non-contact measurement of human body temperature," which is a diagnostic function, not a therapeutic one.
Yes
The device is described as an "infrared thermometer intended for the non-contact measurement of human body temperature," which is a diagnostic function because it measures a physiological parameter to assist in health assessment.
No
The device description clearly states it is a "handheld, battery powered, infrared forehead thermometer" with an LCD screen, indicating it is a physical hardware device that measures temperature. While it can transmit data to software, the core medical device is the thermometer itself.
Based on the provided information, this device 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 Clever Forehead Thermometer/Clever Medical Forehead Thermometer measures body temperature by detecting infrared energy emitted from the forehead. This is a non-invasive measurement taken directly from the body, not from a sample taken from the body.
- Intended Use: The intended use is for "non-contact measurement of human body temperature," which is a physiological measurement, not a diagnostic test performed on a sample.
Therefore, the device falls under the category of a medical device used for physiological monitoring, not an in vitro diagnostic device.

Summary of Performance Studies
A clinical accuracy testing evaluated 250 subjects which were performed on the following three age groups: infants (newborn to one vear), children (greater than one to five years), and adults (greater than five years old) in accordance with ASTM standard (E1965-98) to compare the Clever Forehead Thermometer/Clever Medical Forehead Thermometer with the comparator method (WelchAllyn SureTemp PLUS model 690 Thermometer). This clinical accuracy study demonstrated that the temperatures obtained with the Clever Forehead Thermometer/Clever Medical Forehead Thermometer were highly related when compared to the comparator method. The clinical bias with stated uncertainty and clinical repeatability as defined in the ASTM standard (E1965-98) were within clinical acceptability.

Clinical Testing
A clinical accuracy testing evaluated 250 subjects which were performed on the following three age groups: infants (newborn to one vear), children (greater than one to five years), and adults (greater than five years old) in accordance with ASTM standard (E1965-98) to compare the Clever Forehead Thermometer/Clever Medical Forehead Thermometer with the comparator method (WelchAllyn SureTemp PLUS model 690 Thermometer). This clinical accuracy study demonstrated that the temperatures obtained with the Clever Forehead Thermometer/Clever Medical Forehead Thermometer were highly related when compared to the comparator method. The clinical bias with stated uncertainty and clinical repeatability as defined in the ASTM standard (E1965-98) were within clinical acceptability.
Conclusion
The intended use of the subject device, the Clever Forehead Thermometer/Clever Medical Forehead Thermometer, is identical to that of the predicate device, the Caregiver Professional Clinical Thermometer, PRO-TF series (Model PRO-TF300), and a risk analysis was performed to identify risks associated with the device modifications. Verification tests have been performed to demonstrate that the identified risks have been mitigated. The testing and analysis demonstrate that the subject device is substantially equivalent to the predicate device
