The description focuses on standard temperature measurement technology and does not mention any AI/ML components or algorithms.
No
The device is described as a "temperature monitoring system" intended to "measure and monitor core body temperature," which is a diagnostic function, not a therapeutic one. It does not actively treat or mitigate a disease or condition.
Yes
The device "measure[s] and monitor[s] core body temperature," which is a physiological parameter. This information can be used to aid in the diagnosis or treatment of a condition, aligning with the definition of a diagnostic device.
No
The device description explicitly states it is comprised of a disposable Sensor Unit and a Monitor Connecting Unit, which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "measure and monitor core body temperature of patients of all ages, by applying a sensor unit on the forehead." This describes a device that interacts with the patient's body externally to measure a physiological parameter.
- Device Description: The description details a system with a sensor applied to the forehead and connected to a monitor. This is consistent with a non-invasive physiological monitoring device.
- Lack of IVD Characteristics: IVD devices are designed to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not involve the analysis of such specimens.
Therefore, the TTP™ is a non-invasive physiological monitoring device, not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Study type: Software Validation; Bench testing according to ASTM E-1112-00; Clinical testing through a clinical study according to ISO80601-2-56.
Software Validation: The software was validated to assure the full functionality of the TTP. The device software was validated successfully as device is fully function.
Bench testing: The device passed all bench tests successfully as it withstands acceptance criteria for each and every bench test performed.
Clinical study: The purpose of the clinical study was to demonstrate there is no statistically significant difference between temperatures measured by Temple Touch Pro™ and by other invasive thermometers.
