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 Description
The proposed device, Electronic Thermometer, is a handheld device with battery power supply, 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. There is no specific use of this device other than temperature measurements, including conversion of temperatures. The proposed device is available in two models, which are WT1 and WT2. Similarities between models: a. Both of them incorporate a temperature sensitive sensor b. Both of them can measure and monitor human body temperature under arm; C. Neither the WT1 nor WT2 has display function, the measured or monitored temperature will be transmitted to a mobile application, Temp Sitter, installed under iOS system via the blue tooth to display the measured and monitored temperature; Differences between models: a. WT1 has an automatic power on/off feature; b. WT1 can be used with an adhesive tape, which could be fix the thermometer under arm for measuring and monitoring; c. WT2 can be used with a designated probe cover; d. WT2 can be used for measurement of oral temperature.

The description focuses on basic temperature measurement and transmission via Bluetooth, with no mention of AI/ML terms or functionalities.

No
Explanation: The device is an electronic thermometer intended for measuring and monitoring human body temperature. Its function is diagnostic/monitoring, not therapeutic.

No

Measuring body temperature is a monitoring function, not a diagnostic one. While changes in body temperature can be indicators of illness, the thermometer itself does not diagnose a condition; it merely provides a data point. The "Intended Use" clearly states it is for "measuring and monitoring human body temperature," which supports this non-diagnostic function.

No

The device description explicitly states it is a "handheld device with battery power supply" and incorporates a "temperature sensitive sensor," indicating it is a physical hardware device, not software only.

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 human body temperature. This is a direct measurement of a physiological parameter within the body, not an analysis of samples taken from the body (like blood, urine, or tissue).
  • Device Description: The device description confirms it's a thermometer for measuring body temperature. It doesn't mention any components or processes related to analyzing biological samples.
  • Performance Studies: The performance studies focus on the accuracy and safety of the thermometer itself, not on the performance of a diagnostic test on a sample. The mention of ISO 10993 standards relates to the biocompatibility of the device in contact with the body, which is relevant for medical devices but not specifically for IVDs.

IVD devices are designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This electronic thermometer does not perform such analysis.

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.

    1. 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.
