Wearable medical devices voice alarm circuit diagram

Description: The circuit is primarily composed of the integrated voice chip ISD2560. The Winbond ISD2560 is a chip with robust voice recording capabilities, featuring a permanent memory circuit for voice recording. It has a recording duration of 60 seconds and can be reused up to 100,000 times. The chip employs patented multi-level direct analog storage technology, allowing for highly realistic and natural voice reproduction. The system is designed to provide automatic voice prompts for blood pressure measurements. If the recorded blood pressure exceeds the normal range, it will play an alarm to notify the user to consult a doctor. Specifically, after a designated period (approximately one month) of accurate measurements, data is processed on a computer to establish the normal blood pressure range, which sets the lower limit for alarm thresholds. The device continuously monitors the user's blood pressure, and if it exceeds the normal range, it records the time and date of the occurrence. If the blood pressure remains outside the normal range for more than five minutes, an alarm is triggered with a message: "Dear user, hello. Please lower your high blood pressure. We recommend that you measure your blood pressure immediately and take appropriate medication!"

The ISD2560 voice chip is central to this circuit, functioning as a voice recorder and playback device that utilizes a simple interface for ease of integration into various applications. The design includes a microphone input for capturing audio, which is then stored in the chip's built-in memory. The playback mechanism can be activated through specific triggers, such as exceeding predefined blood pressure thresholds.

The circuit typically includes additional components such as an operational amplifier to enhance the microphone signal, a microcontroller to manage the logic of the blood pressure monitoring and alarm system, and possibly a power supply circuit to ensure stable operation. The microcontroller receives input from a blood pressure sensor, processes the data, and determines if the recorded values fall outside the normal range.

The alarm system is designed to provide timely warnings to the user, enhancing the usability of the device for health monitoring. The voice prompts are stored in the ISD2560 and can be customized based on user preferences or specific health guidelines. The overall design is aimed at creating a user-friendly interface that facilitates proactive health management, particularly for individuals with hypertension. This circuit can be further enhanced with features such as Bluetooth connectivity for data logging and analysis through mobile applications, allowing for comprehensive health tracking and management. Circuit as shown, mainly by the integrated voice chip ISD2560 composition. Winbond ISD2560 is produced by a chip with a strong voice recording function, it is a permanent memor y circuit voice recording, the recording time is 60s, recording can be repeated 100,000 times. The chip uses multi-level direct analog storage technology patents, can be very real, natural reproduction of voice. Good sound by recording in advance, to achieve blood pressure measurement automatically voice prompts, if blood pressure is higher than normal blood pressure, upper and lower limits, but also play an alarm to alert the user to a doctor.

Specifically: after a period of time (approximately normal month) for accurate measurement, data processing on a computer, to give the normal range of blood pressure, which is the lower limit set alarm range, constantly monitor the wearers blood pressure, if blood pressure beyond the normal range, the start time, the date and time data to be recorded, if outside the normal range for longer than five minutes, then began to alarm to remind, suggesting content: Dear users Hello, this time lower your high blood pressure, we recommend that you measure the voltage immediately and take appropriate medication!
