Electronic intelligent blood glucose meter industry background:
The electronic blood glucose meter has appeared in the medical market for some time, but many users still cannot use the electronic blood glucose meter correctly. Because the user group dominates the middle -aged and elderly people, many elderly people have decreased vision. It is difficult to see the blood sugar results after the test. The application of electronic blood glucose meters encounters a certain bottleneck, making it unable to play a big role.
The meaning of blood glucose meter plus voice
How to improve the electronic blood glucose meter can it greatly use its application effect? In response to the problems encountered in the use of electronic blood glucose meters, a medical company adds a voice chip to the blood glucose meter to make the electronic products that "not speak" and enter the era of the blood glucose meter. It is a good for the blood glucose meter market. Reform.
The voice blood glucose meter makes the entire blood glucose detection process simple and clear. There are voice reminding each operation step. Users get started quickly. For middle -aged and elderly people, it is more convenient to use. The following figure is the voice blood glucose meter of the voice IC.
Example of voice content
The general voice prompts during the use of voice blood glucose meters are as follows:
1. Press the start -up key, the blood glucose meter automatic reminder: "Welcome to use the XX company blood glucose meter, please pay attention to your health!";
2. After waiting a few seconds, the blood glucose meter began to prompt: "Please use 75%of alcohol to disinfect the fingertips, please insert the test strip into the machine, and start the blood after the alcohol is dry.";
3. After the blood collection is over, the blood glucose meter will play the current value according to the test results of the test strip, and determine whether it is a normal value: "The current blood sugar concentration is xxx, which is a normal value";
4. After using the blood glucose meter, press the shutdown key, and a warm reminder before the end of the blood glucose meter: "Please press your finger for 10 seconds with a cotton stick for 10 seconds. Thank you for your health!";
Recommended voice IC
When developing voice blood glucose instruments, many blood glucose meters do not know how to choose the voice IC that suits them.
The following introduces a voice chip that is currently widely used in the voice chip of the voice blood glucose meter-Guangzhou Jiuxin Electronics. The NVC series voice chip is a programmable disposable firing (OTP) voice chip, built -in 16bits DAC digital/simulation converter, long -recording 180s voice duration and sound quality optimization algorithm, which can show relatively high -quality audio, built -in built -in built -in The 0.5W speaker is directly pushed the line and the power -saving mode consumes 2UA. In the power saving mode, the chip is automatically dormant after the chip is powered by 1 second or the voice is stopped for 1 second after being played.
