Phone: +86 (512) 6809-1772 Fax: +86 (512) 6809-7761 www.bca-medical.com #### ● Descriptions The Digital Thermometers, 1004/1005, enable easy and accurate measuring over the body temperature range. It must be used in conjunction with a disposable probe cover when measuring temperature. From the construction point of view, the digital thermometer comprises of a thermistor for temperature sensing, a reference resistor for comparison of temperature, a buzzer for sounding effect, an application specified IC for calculating, and an LCD for displaying the measured temperature reading which the thermistor contacts and senses. #### ● Test Principle The Digital Thermometers, 1004/1005, are the electronic thermometers operated by a thermistor as the temperature sensor and an application specified IC for signal processing. The basic operation principle is that a change of thermistor, caused by changes of temperature, provides a signal to application specified IC. Application specified IC gets the sensor's signal, then processes the signal and calculates the result. After that, it displays the temperature result on an LCD display. #### ● Features - . Patient having an elevated temperature: indicated by red lit screen and audio beep when above 99.7 °F / 37.6 °C - . Measurement time: approximately 8-10 seconds (Predictive mode) and approximately 60 seconds (Non-predictive mode) - LCD read-out with °F / °C switchable - Flexible tip - I Automatic shutoff when idle for 180 sec - . Memory: The last reading is automatically displayed for 2 seconds when the unit is witched ON. Up to 9 sets of memory can be stored. - .

Phone: +86 (512) 6809-1772 Fax: +86 (512) 6809-7761 www.bca-medical.com #### Substantial Equivalence Discussion ● - A claim of substantial equivalence is made to Kingtech Digital ● Thermometer TT1001 (K133111). The indications for use. the measurement principle and technologies are the same. There are no new concerns raised. - The subject device has two more sites choices than PD, i.e. under arm or rectum sites. Since the accuracy performances under arm and rectum sites are validated by the relevant bench performance testing, there are no safety or effectiveness concerns raised. - The storage temperature range of the subject device is different from those of PD, and the maximum storage humidity ranges of both devices are to be 95% RH or less. The storage conditions are confirmed to be effective and safe after we did the storage environment testing. If the user stores the subject device according to the prescribed storage conditions, there is no any concern raised. - Both of them use the same button-like batteries but with different voltages. The battery information is shown in the user manual and on the device itself, and the users can replace and install a correct type battery without question. There is no concern raised. - The slight differences of maximum measurement points 109.2 °F for the subject device are 2 degrees less than PD. Since these differences are so small, thev will not raise any new concern. - The accuracies of the subject and predicate devices are different. The subject device passes the relevant accuracy testing, in which results show the accuracies as - ±0.1 °C at 33.0 °C. ±0.1 ºC at 36.0 ºC ±0.1 °C at 38.0 °C. ±0.1 °C at 40.0 °C ±0.1 °C at 42.0 °C for different temperature ranges. PD has the same accuracy of ±0.2 °F for the range of 98 F to 102.2 F. For the range of 98 °F to 102.2 °F the accuracy of the subject device is around ±0.18 °F. So the differences of accuracies did not raise any concern. - Weight of the subject device is 30g, and PD is 15g. Since most of the users are healthcare professional and the different weights will not pose any adverse events for the patients. There is no new concern raised. - The size dimensions of the PD and subject devices are different. This is caused by the different designs of the main housing and electric board. There is no new concern raised. {8}------------------------------------------------ NO.260, MAYUN ROAD, NEW DISTRICT SUZHOU, JIANGSU, 215129, P.R.C. Phone: +86 (512) 6809-1772 Fax: +86 (512) 6809-7761 www.bca-medical.com - The instructions for cleaning & disinfecting the device after each use with 75% isopropyl alcohol are the same for subject and predicate devices. There is no new concern raised. - The auto power off functions for the subject device is when idle for 180 sec and PD is 10 min idle. We can say the subject device has better performance of energy saving. There is no new concern raised. - The color parts of subject and predicate devices are different due to the various colorants/dyes added. But subject and predicate devices are all required to be used with probe covers for patient-contacting materials. The patient-contacting materials are probe covers, not the various color parts. Especially, the probe cover used with the subject device is already 510(k) cleared (K102508). The patient-contacting materials all passed biocompatibilities testing, and the various probe covers and different color parts did not raise new safety and effectiveness concerns. #### ● Summary of non-clinical testing ### 1) Electrical Safety, EMC and Biocompatibility Test - IEC/ EN 60601-1 2012+ CORR.1 (2014) Medical electrical equipment Part 1: General requirements for basic safety and essential performance - IEC/EN 60601-1-11:2010 Medical electrical equipment Part 1-11: General requirements for basic safety and essential performance - Collateral Standard: Requirements for medical electrical equipment and medical electrical systems used in the home healthcare environment - IEC/ EN 60601-1-2:2007+AC:2010 Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral standard: Electromagnetic compatibility - Requirements and tests - ISO 10993-1:2009 Biological evaluation of medical devices -- Part 1: Evaluation and testing within a risk management process - ISO 10993-5:2009 Biological evaluation of medical devices -- Part 5: Tests for in vitro cytotoxicity - ISO 10993-10:2010 Biological evaluation of medical devices -- Part 10: Tests for irritation and skin sensitization {9}------------------------------------------------ NO.260, MAYUN ROAD, NEW DISTRICT SUZHOU, JIANGSU, 215129, P.R.C.
