Intended Use

The device is an electronic clinical thermometer using a thermistor to detect body temperature from the oral , armpit , and rectal in neonatal , pediatric and adult population used in the clinical and home testing .

Device Story

Electronic clinical thermometer using thermistor sensor to detect body temperature; ASIC (Application Specific IC) processes thermistor electrical signals; compares against reference resistor; calculates target temperature; displays on LCD. Features include buzzer for audible alerts, battery level monitoring, and water-resistant housing. Models vary by tip type (flexible vs. rigid) and button placement. Used by clinicians or patients in clinical or home environments. Provides rapid temperature readings (within 10 seconds in 37°C water bath). Output assists healthcare providers in assessing patient febrile status.

Clinical Evidence

Controlled human clinical studies compared the subject thermometers to predicate devices. Readings were validated against conventional/accepted oral or rectal temperature measurement methods. Bench testing confirmed compliance with ASTM E 1112-2000, IEC 601-1-1, and IEC 601-1-2 standards.

Technological Characteristics

Thermistor-based temperature sensing; ASIC-driven signal processing; 1.55V battery power; LCD display; water-resistant housing; flexible or rigid tip configurations. Complies with ASTM E 1112-2000, IEC 601-1-1, and IEC 601-1-2.

Indications for Use

Indicated for body temperature measurement via oral, axillary, or rectal routes in neonatal, pediatric, and adult populations in clinical 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.
