The description details a simple electronic thermometer based on a thermistor and R-C oscillator circuit, with no mention of AI or ML.
No
The device is intended to measure temperature, which is a diagnostic function, not a therapeutic one. Therapeutic devices are designed to treat or alleviate a medical condition.
No
The device is a thermometer, which measures temperature. While temperature can be an indicator for various conditions, the device itself simply provides a measurement and does not interpret this measurement to diagnose a medical condition.
No
The device description explicitly details hardware components such as a thermistor, nipple made of medical silicon rubber, and a body made of ABS hard plastic, indicating it is a physical device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD devices are used to examine specimens derived from the human body. This device measures the temperature of the human body directly (oral temperature).
- The intended use and device description clearly state it measures oral temperature. This is a physiological measurement, not a diagnostic test performed on a sample.
- The performance studies focus on the accuracy of temperature measurement. This aligns with the function of a thermometer, not an IVD.
The device is a clinical electronic thermometer, which is a medical device, but it does not fit the definition of an In Vitro Diagnostic device.

Device Description
Digital Pacifier Thermometer TM-03 is a reusable, battery-operated clinical electronic thermometer, with which a thermistor installed inside the nipple, for use by medical professional or at home. Different from the traditional electronic thermometer, our TM-03 is designed specifically for the measuring the oral temperature of baby or little child. Therefore, our TM-03 is molded as a pacifier. The patient contact portion is the thermometer's nipple which is made of medical silicon rubber. The body of TM-03 is then manufactured by ABS hard plastic.
TM-03 utilizes the phenomenon of thermal conductivity changes of our selected NTC thermistor when there are changes of external environment temperature. Whenever the external temperature changed, the resistance of our thermistor changed uniformly. Then, the changes in resistance are converted to the changes of frequency of R-C oscillator circuit. This means TM-03 keep monitoring the frequency of the oscillator and the temperature can be measured accurately.

Summary of Performance Studies
A systematic & independent clinical test was conducted to validate the performance of the Digital Pacifier Thermometer (Model No. TM-03). The results demonstrated that our device (Model No. TM-03) meets the requirement of +/-0.2°F for 95°F – 107.6°F. Also, we have asked an independent laboratory to test the accuracy of our device (Model No. TM-03) based on the ASTME1112 and the results further verified our device meets the requirement of +/-0.2°F for 95°F - 107.6°F.
For the electrical safety of our device, comprehensive testings were carried out according various international standards. Firstly, our devices are tested and compiled with the EN60601-1 (Standard Title: Medical Equipment Part 1: General requirements for safety), which includes a collective of safety tests. Then, the electrical safety of our devices is further verified via conducting the electromagnetic compatibility test according to FCC Part 15 and IEC60601-1-2. The results classified and demonstrated our devices as Class B device and are compiled with the acceptance limit (40dB (uV/m)).
Furthermore, we have conducted various tests on the safety of material to verify our device (Model No. TM-03) was made by safe material. Firstly, we applied the ISO10993 sets to test the biocompatibility of our device. The results showed no evidence of causing delayed dermal contact sensitization. And our device is classified as a non-irritant and not a cytotoxic potential. Secondly, we tested the silicon nipple of our device with US Compliance Policy Guide Part 7117.11 for nitrosamine content in rubber baby bottle nipples. We notice that the testing scope of Policy Guide Part 7117.11 was not applicable to our product category. However, we still would like to have a reference on the safety towards nitrosamine content in our device (Model No. TM-03). The results demonstrated our device is safe and within the corresponding acceptance limit (10ppb). Thirdly, our device/device components not made with BPA. BPA is not used in the manufacture of the accessible parts of the device (TM-03).
