Technological Characteristics
Thermistor-based sensing; RC oscillator circuit for frequency conversion; curved probe tip; digital display. Complies with ASTM E1112, IEC 60601-1, and IEC 60601-1-2 standards.
Indications for Use
Indicated for intermittent measurement and monitoring of oral human body temperature in patients aged 18 months and older.
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.

### 510(K) SUMMARY
This summary of 510(k) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR §807.92.
The assigned 510(k) number is:
- 1. Submitter's Identification:
Microlife Intellectual Property GmbH, Switzerland Espenstrasse 139 9443 Widnau / Switzerland Date Summary Prepared: February 22, 2007
- 2. Name of the Device: Microlife Instant Digital Electronic Thermometer, Model MT19S1R
- 3. Predicate Device Information: Microlife Instant Digital Electronic Thermometer, Model MT1811, K#04310.
- 4. Device Description:
This Instant Digital Electronic Thermometer enables very fast and reliable measurements and with its predicative technology the thermometer offers a very high clinical accuracy and has been designed to provide a maximum of user-friendliness.
The basic principle of this thermometer's that change of thermistor resistance, caused by changes of temperature, are converted to changes of frequency of RC oscillator circuit, Therefore, temperature can be given by measuring the frequency of oscillator.
- ട്. Intended Use:
Microlife MT1 951 R Instant Digital Electronic Thermometer is used for the intermittent measurement and monitoring of oral human body temperature. The intended use of this thermometer is for ages 18 months and above.
EXHIBIT #la-l
{1}------------------------------------------------
### ର. Comparison to Predicate Devices:
The Microlife Instant Digital Electronic Thermometer, Model MT1 951 R is substantially equivalent to Microlife Instant Digital Electronic Thermometer, Model MTI8I1, K#043110 which has the similar intended use and is similar in design to the predicate device.
The Microlife Instant Digital Electronic Thermometer MT1 9S1R and the predicate device are identical in the temperature measurements algorithm and fundamental scientific technology. They mainly differ in the "Try again" function. When abnormal action is detected, the thermometer will stop playing the melody and displa\/ ---- and hear if Try again" speaking. The subject device also differs from the predicate device in measuring location, melody Great Job, curve probe tip and shape. In all, these differences do not affect the accuracy and normal use of this device because they use the same fundamental scientific technology, therefore, they are substantial equivalent.
### Discussion of Non-Clinical Tests Performed for Determination of Substantial Equivalence 7. are as follows:
Compliance to applicable voluntary standards includes ASTM £1112, as well as 1EC60601-1 and 1EC60601-l-2 requirements.
Guidance documents included the FDA Guidance on the Content of Premarket Notification 510(K) Submissions for Clinical Electronic Thermometers.
- 8. Discussion of Clinical Tests Performed:
Controlled human clinical studies were conducted using the Microlife Instant Digital Electronic Thermometer, Model MT1 951 R. Clinical data was presented which evaluated clinical bias, clinical uncertainty and clinical repeatability per the Microlife Clinical Test Protocol outline.
#### 9. Conclusions:
The Microlife Instant Digital Electronic Thermometer, Model MT1 9S1 R has the similar intended use and similar technological characteristics as the Microlife Instant Digital Electronic Thermometer, Model MT1BI1. Moreover, bench testing contained in this submission supplied demonstrates that any differences in their characteristics do not raise any new questions of safety or effectiveness. Thus, the Microlife Instant Digital Electronic Thermometer, Model MT19S1R is substantially equivalent to the predicate device.
