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.

### 3.0 Classification: Class II

### 4.0 Predicate Device Information:

Actherm digital clinical thermometer Model: ACT 2000. It's 510(K) number is K010238

#### 5.0 Device Description:

Famidoc Digital Clinical Thermometer (model FDTH-V0-1, FDTH-V0-2, FDTH-V0-3, FDTH-V0-4) are hand-held, reusable, battery operated, maximum device that can measures human body temperature.

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

Models FDTH-V0-1, FDTH-V0-2, FDTH-V0-3, FDTH-V0-4 have the same indication for use. the difference points are their shapes、waterproof function and measurement speed.

The operation principle is based on thermistor and ASIC technology, a thermistor using as temperature sensor, the sensor's signal is then calculated and displayed by an ASIC. The digital thermometer comprises a thermistor for temperature sensing, a reference resistor for comparing the resistance of the thermistor, a buzzer for sounding effect, an ASIC and a LCD for calculating and displaying the target temperature digitally which the thermistor is immersed.

### 6.0 Intended Use:

Famidoc Digital Clinical Thermometer Model FDTH-V0-1、FDTH-V0-2、 FDTH-V0-3、 FDTH-V0-4 are intended for the measurement and monitoring of human body temperature by doctor or consumers in the hospital or home. It is used alone for human beings at all ages.

#### 7.0 Measurement Type:

There are three measurement types to use our thermometer. Axillary measurement, Oral measurement and rectal measurement, when used under the Axillary, it directly contacts body skin. For oral or rectum use, it directly contacts membrane tissue.

#### 8.0 Performance Data:

The devices meet the ASTM Standard Specification for Electronic Thermometer for intermittent Determination of Patient Temperature ( ASTM Ell12-00 ), as well as IEC 60601-1 and IEC 60601-1-2 requirements, Bench testing confirmed accuracy, precision and repeatability measurements specified in the labeling. For all body contacting materials, analysis is made that the identical materials have been used in other legally marketed devices under the same use conditions (see Chapter 8 Safety and Effectiveness Evaluation and Risk Analysis, Chapter 10 Biological Compatibility Report). And we had made clinical tests to prove its repeatability and standard deviation are accord with the demand of EN 12470-3:2000 when applied human.
