Wearable medical device voice alarm circuit diagram

The circuit is shown in the figure and is mainly composed of the integrated voice chip ISD2560. ISD2560 is a voice recording and playback chip with strong functions produced by Winbond Company. It is a permanent memory voice recording and playback circuit. The recording time is 60s and can be repeated 100,000 times. The chip uses patented multi-level direct analog storage technology to reproduce speech very realistically and naturally. Through pre-recorded sounds, automatic sound prompts for blood pressure measurement values ​​are realized. If the blood pressure is higher than the upper and lower limits of normal blood pressure, an alarm will be activated to remind the user to seek medical treatment. Specific method: After a period of accurate measurement (about one month for a normal person), process the data on the computer to obtain the normal range of blood pressure, set its upper and lower limits as the alarm range, and monitor the wearer's blood pressure value from time to time. If the blood pressure If it exceeds the normal range, the timer will start and the date, time and other data will be recorded. If the time exceeds the normal range for more than five minutes, an alarm will start. The prompt content is: Dear user, your blood pressure is high or low at this time. , it is recommended that you perform a voltage measurement immediately and take the corresponding medicine!
