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.

### 4.0 Device description
Fudakang digital thermometers are hand-held, reusable, battery operated. The models include BT-A11CN, BT-A21CN, and BT-A41CN. All the models have the same indication for use. The difference points are their shapes, colors, voice function, and measurement speed.
The operation principle is based on thermosensor and ASIC technology. A thermistor is used as thermosensor. The ASIC gets the sensor's signal from human body, then processes the signal and calculates the result, after that displays the temperature result by a LCD. The digital thermometer comprises a thermistor for getting temperature signal, a reference resistor for comparing the resistance of the thermistor, a buzzer for sounding effect, an ASIC for processing the target temperature digitally, and a LCD for displaying the temperature result.
#### 5.0 Intended Use
Fudakang Digital The mometers are intended for the measurement and monitoring of human body temperature by doctor or consumers in the hospital or home.
#### 6.0 Performance Summary
The devices meet the ASTM Standard Specification for Electronic Thermometer for intermittent Determination of Patient Temperature ASTM E1112-2006, as well
Section 5, Page 5-2
{2}------------------------------------------------
as IEC 60601-1 and IEC 60601-1-2 requirements. The bench test confirmed that the accuracy, precision and repeatability of device are compliance with ASTM E1112-2006 requirements.
The thermometers can be used for axillary, oral and rectal measurement. For axillary use, it directly contacts body skin. For oral or rectum use, it directly contacts membrane tissue. The patient contact materials in the device are made of stainless steel, ABS plastic, and thermoplastic rubber. They are all compliance with ISO10993-1 biocompatibility requirements, and pass the ISO10993-5 and ISO10993-10 tests.
#### 7.0 Comparison to predicate device and conclusion
Compare with predicate device, they are very similar in design principle, intended use, functions, material and the adopting applicable standards. The differences between applicant device and predicate device do not raise and new questions of safety or effectiveness.
l ). Indication for use
Famidoc Digital Clinical Thermometer can be used for axillary measurement, oral measurement and rectal measurement. Fudakang Digital Thermometers, BT-A11CN, BT-A21CN, BT-A41CN have the same measurement application.
2). Environment conditions
The environment conditions of Fudakang Digital Thermometers are a little different from Famidoc Digital Clinical Thermometer. But they are both compliance with IEC 60601-1 and ASTM E1112 requirements. So the difference of environment conditions will not raise any safety or effectiveness issue.
3). Accuracy
The accuracy of subject device is: 95.0 - 102.0 F : +/- 0.2 F 35.0 - 39.0℃: +/- 0.1℃ The rest: +/- 0.2°C - - -
The accuracy of predicate device is: +/- 0.1℃ (0.2F ) for whole range
Although there is a little difference, but the subject device accuracy is compliance with ASTM E 1112 requirements. So the difference of accuracy will not raise any safety or effectiveness issue.
4). Response time
{3}------------------------------------------------
The Subject Device is 60s. The Predicate Device is 30s.
The Response time of Fudakang Thermometers is a little different from Famidoc Digital Clinical Thermometer. They are all compliance with IEC 60601-1 and ASTM E 1112 requirements. The difference of Response time will not raise any safety or effectiveness issue.
Conclusions: Fudakang Digital Clinical Thermometers, model: BT-A11CN, BT-A21CN, BT-A41CN are substantially equivalent to the predicate devices.
