Intended Use

The Microlife Digital Infrared Ear Thermometer, Model IR1DR1-1 device, is an electronic clinical thermometer using an infrared sensor to detect body temperature from the auditory canal in the neonatal, pediatric and adult population used in the home setting.

Device Story

Device is an electronic infrared ear thermometer for home use. It utilizes a thermopile sensor to detect natural thermal radiation from the tympanic membrane and surrounding auditory canal tissue. Infrared energy is captured by a lens, converted into temperature values by an application-specific integrated circuit (ASIC), and displayed on an LCD. Features include a position indication system to assist with probe placement and an elevated temperature alarm (audible beeps if >37.5°C). Operated by the user via Start and O/I keys. Output is a digital temperature reading used by the patient or caregiver to monitor body temperature. Benefits include non-invasive, rapid temperature assessment.

Clinical Evidence

Clinical validation conducted per ASTM E1965-98 and IEC 80601-2-56. Studies evaluated clinical uncertainty and clinical repeatability of the IR1DR1-1. Results demonstrated the device meets performance requirements for accuracy and repeatability in the intended population.

Technological Characteristics

Infrared thermopile sensor (TPS23B); lens-based optical system; ASIC-based processing; LCD display with backlight; 3.0V battery power. Dimensions: 7.3mm tip width. Connectivity: None. Sterilization: Not applicable (non-sterile). Software: Embedded firmware for temperature calculation and position indication.

Indications for Use

Indicated for neonatal, pediatric, and adult populations for body temperature measurement via the auditory canal in a home setting.

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.

The indications for use statement and the intended use of the subject device is identical to the predicate device. The differences in the device are:

- 1. Measurement temperature range has been narrowed to more physiologically relevant temperatures. This does not introduce any new risk to the device.
- 2. Addition of the Position Indication Feature, which has been validated and verified through performance testing and clinical testing.
- 3. The integrated circuit model and its features have changed. These changes have been verified through performance testing.
- 4. The thermometer's memory can recall the last temperature measurement, which has been decreased from predicate which recalled the last 12 temperature measurements.
- 5. The Probe head and the rest of the device is dimensionally larger than the predicate device. This does not change how the device operates. The size difference was validated through clinical studies.
- 6. The operating condition has been narrowed. .

Based on the aforementioned modifications to the subject device, the subject device does not raise different types of safety and effectiveness questions when compared to the predicate device.
