Regulatory Classification
Identification
A clinical electronic thermometer is a device used to measure the body temperature of a patient by means of a transducer coupled with an electronic signal amplification, conditioning, and display unit. The transducer may be in a detachable probe with or without a disposable cover.
Special Controls
(1) Device is not a clinical thermometer with telethermographic functions; (2) Device is not a clinical thermometer with continuous temperature measurement functions; and (3) Appropriate analysis and testing (such as that outlined in the currently FDA-recognized editions, as appropriate, of ISO 80601-2-56, “Medical electrical equipment—Part 2-56: Particular requirements for basic safety and essential performance of clinical thermometers for body temperature measurement,” or ASTM E1965, “Standard Specification for Infrared Thermometers for Intermittent Determination of Patient Temperature,” or ASTM E1112, “Standard Specification for Electronic Thermometer for Intermittent Determination of Patient Temperature,” or ASTM E1104, “Standard Specification for Clinical Thermometer Probe Covers and Sheaths”) must validate specifications and performance of the device.

### Proposed product: Digital Thermometer
Discussion of the differences:
The Digital Thermometer (Model: TP-100, TP-200, TP-400, TP-500, BT-A31A-BT) has similar indications for use and technological characteristics as the predicate device:
Digital Thermometer has the same intended use as the predicate device (K152739) : to measure human body temperature orally and/or under arm for adult, pediatric and infant.
The same and/or similar technologies and parameters are used in digital thermometers as the predicate device. The identified differences in technological characteristics do not raise new or different questions of safety and effectiveness. Although some specifications are slightly different from the predicate device, the thermometer quality has been verified and validated as a part of performance testing and safety /EMC testing and the results are included as a part of this submission. Performance information and evidence of compliance to recognized standards demonstrate the device is substantially equivalent to the predicate device.
The targeted device may connect to iOS device and Android device through wireless method, but the predicate device can only connect to iOS device. Risk analysis and associated verification (include cybersecurity test, FCC test and wireless verification) have been performed that the wireless feature is acceptable.
Both devices use similar materials for construction and have direct skin surface contact. The biocompatibility test reports for the different materials have been provided to determine the biocompatibility of the subject device. Based upon the same intended use, similar materials for device construction, product specification and operation, as well as performance testing, it could be concluded that the Digital Thermometer (Model: TP-100, TP-200, TP-300, TP-500, BT-A31A-BT) is substantially equivalent to the predicate device.
#### 7. Non-clinical studies and tests performed
Non-clinical tests were conducted to verify that the targeted device meet all design specifications in order to demonstrate that it is Substantially Equivalent to the predicate device.
The test results demonstrate that the targeted device complies with the following standards: IEC 60601-1Medical electrical equipment –Part 1: General requirements for basic safety and essential performance
IEC 60601-1-2 Medical electrical equipment -Part 1-2: General requirements for basic safety and essential performance -Collateral standard: electromagnetic compatibility
