Intended Use

Electronic Thermometer is intended for measuring and monitoring human body temperature orally and/or under arm for adult, pediatric and infant. It can be used in healthcare facility and home.

Device Story

Handheld electronic thermometer (models WT1, WT2) measures human body temperature via temperature-sensitive sensor; transmits data via Bluetooth to iOS mobile application 'Temp Sitter' for display. WT1 uses adhesive tape for under-arm monitoring; WT2 uses probe covers for oral/under-arm use. Operated by patients or healthcare providers in home or clinical settings. Output consists of temperature readings displayed on mobile device; assists in monitoring body temperature. Benefits include remote monitoring capability and non-invasive temperature tracking.

Clinical Evidence

No clinical data. Bench testing only, including biocompatibility (ISO 10993-5, ISO 10993-10), electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), and performance testing per ISO 80601-2-56.

Technological Characteristics

Battery-powered handheld device; temperature-sensitive sensor; Bluetooth connectivity to iOS app. Materials: Stainless Steel (S216), Polycarbonate (PC 2458), Silicone, TPE, non-woven cloth, medical melt adhesive. Standards: ISO 10993-5/10, IEC 60601-1, IEC 60601-1-2, ISO 80601-2-56. No display on device; data transmitted to mobile app.

Indications for Use

Indicated for measuring and monitoring human body temperature orally and/or under arm for adult, pediatric, and infant populations in healthcare facilities or home settings.

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.

Discussion of Main Differences:

The proposed device can only measure orally and/or under arm, however, the predicate device can additionally measure rectal temperature. The intended sites have been communicated in the user manual, and this will not affect the intended use of the device; the proposed device connects with the iOS device through wireless method, however, the predicate device connects the iOS device through cable. Risk analysis and associated verification has been performed that the wireless feature is acceptable; In addition, the proposed device has a longer response time, however, this time is still acceptable and communicated in the User Manual.

- 9. Substantially Equivalent (SE) Conclusion
Based on the comparison and analysis above, the proposed devices are determined to be Substantially Equivalent (SE) to the predicate devices.
