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.

## 2. Name of the Device:

Microlife Digital Infrared Forehead Thermometer, Model FR1DM1

### Predicate Device Information: 3.

Microlife Digital Infrared Ear Thermometer, Model IR1DE1, K#020725

### Device Description: 4.

The Microlife Digital Infrared Forehead Thermometer, Model FR1DM1 is an ectronic thermometer using an infrared sensor (thermopile) to measure forehead temperature, then get a reading and display it on the LCD.

Its operation is based on measuring the natural thermal radiation emanating from the forehead and the adjacent surfaces.

The Microlife Digital Infrared Forehead Thermometer, consists mainly of five parts:

- a) IR Thermopile Sensor
- b) ASIC
- c) E2PROM IC

{1}------------------------------------------------

- d) LCD and Blacklight
- e) Kev*2, Buzzer*1

### 5. Intended Use:

The Microlife Digital Infrared Forehead Thermometer, Model FR1DM1 is intended for the intermittent measurement and monitoring of human body temperature. The device is indicated for use by people of all ages in the home.

## Comparison to Predicate Devices: 6.

The Microlife Digital Infrared Forehead Thermometer, Model FR1DM1 is substantially equivalent to the original Microlife Digital Ear Thermometer, Model IR1DE1 in all aspects, e.g., technological characteristics, modes of operation, performance characteristics, intended use, etc.,

The major difference between the Microlife Infrared Forehead Thermometer and the predicate device is the measuring site. The predicate device is measuring ear temperature while the subject device is measuring forehead temperature.

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

Compliance to applicable voluntary standards includes ASTM E1965-98, as well as IEC60601-1 and IEC60601-1-2 requirements.

Guidance documents included the "FDA Guidance on the content of Premarket Notification (510(k)) Submissions for Clinical Electronic Thermometers".

## Discussion of Clinical Tests Performed: 8.

Controlled human clinical studies were conducted using the Microlife Infrared forehead thermometer FR1DM1. Clinical data was presented evaluating clinical bias, clinical uncertainty and clinical repeatability per Microlife clinical test protocol for infrared forehead thermometer.

## 9. Conclusions:

The Microlife Infrared Forehead Thermometer, Model FR1DM1, has the same intended use and similar technological characteristics as the Microlife Infrared Ear thermometer Model IR1DE1. Moreover, bench testing contained in this
