More Information

Not Found

No
The summary describes a standard digital thermometer using a thermistor and does not mention any AI/ML terms or capabilities.

No
The device is used for measurement/diagnosis (thermometer), not for treatment or therapy.

No

An electronic thermometer used for clinical temperature measurement is primarily a measurement device, not a diagnostic one. While temperature can be an indicator of health status, the thermometer itself does not provide a diagnosis of a disease or condition; it only provides data.

No

The device description explicitly states it uses a thermistor as a temperature sensor and a battery for operation, indicating it includes hardware components beyond just software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is "clinical temperature measurement." This is a direct measurement of a physiological parameter (body temperature) within the body or on the body surface.
  • Device Description: The device uses a thermistor to measure temperature. This is a physical measurement, not a test performed on a sample taken from the body (like blood, urine, or tissue).
  • Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing a sample (blood, urine, etc.)
    • Detecting or measuring substances in a sample
    • Providing information about a disease state or condition based on sample analysis

IVDs are devices used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This thermometer directly measures a physical property of the body itself.

§ 880.2910 Clinical electronic thermometer.

(a)
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.(b)
Classification. Class II (performance standards). The device is exempt from the premarket notification procedures in part 807, subpart E of this chapter, subject to the limitations in § 880.9 and the following conditions for exemption:(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.

510(K) SUMMARY

2016 (0.152)

This summary of 510(K) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92, and the relevant 510(K) submission guidance.

The assigned 510(K) number is:

1. Submitter's Identifications:

Date Summary Prepared: March 15, 2006

2. Name of the device:

Rapid Digital Thermometer, Model RDT-18-XY (X=0-9, Y=1-9) Classification Name: Thermometer, Electronic, Clinical

3. Predicate Device Information and Substantial Equivalence: Electronic Thermometer GT010706 (K021052).

4. Device Description:

The Rapid Digital Thermometer is an electronic thermometer by using a thermistor as the temperature sensor.

The thermometer uses a 1.5V button battery for operation.

5. Intended Use:

The Rapid Digital Thermometer is an electronic thermometer used to measure body temperature in oral, axillaries (underarm use), and rectal.

6. Comparison to the 510(k) Cleared Device (Predicate Device):

1

K412416 (0.25A2)

The Rapid Digital Thermometer (RDT-18 series) has the same intended use and technological characteristics as the cleared device of Electronic Thermometer GT010706 (K021052). Although there are slight differences between the new device and the legally marketed one, these differences do not affect the safety, performance of the subject device. So the new device is substantial equivalence to the selected predicate device.

7. Discussion of Non-Clinical Tests Performed Determination of Substantial Equivalence are as follows:

Both the predicted device and the Rapid Digital Thermometer (RDT-18 series) are in compliance to applicable voluntary standards. Various performance testing data which conducted according to ASTM E1112 standards, such as temperature range test, accuracy test, resolution test, cleaning test, demonstrate the same safety and effectiveness as that of cleared device.

Also both devices conform to IEC 60601-1, IEC 60601-1-2 requirements, and as well as ISO 10993-1:2003 biocompatibility testing on skin irritation, in vitro cytotoxicity and sensitivity.

Guidance documents included the "FDA Guidance on the Content of Premark Notification (510(k)) Submission for Clinical Electronic Thermometers"

8. Conclusions:

The Rapid Digital Thermometer (RDT-18 series) has the same intended use and technological characteristics as the predicted device. Various performance testing data which conducted according to ASTM E1112 standards, such as temperature range test, accuracy test, resolution test, cleaning test, demonstrate the same safety and effectiveness as that of cleared device. In the other words, the Rapid Digital Thermometer is substantial equivalence to predicted device.
