Development of a wireless blood pressure measuring device with smart mobile device

Area of Science:

• Biomedical Engineering
• Mobile Health (mHealth)
• Medical Devices

Background:

• Smart mobile devices are increasingly prevalent, offering powerful hardware and features.
• The potential for integrating smart mobile devices into biomedical applications is significant.
• Existing blood pressure monitoring methods can be cumbersome and less accessible.

Purpose of the Study:

• To develop a wireless blood pressure measuring device integrated with smart mobile devices.
• To utilize smart mobile devices (Android/iOS) as both indicators and control units for the device.
• To explore the feasibility and accuracy of mobile-integrated vital sign monitoring.

Main Methods:

• Developed a wireless blood pressure cuff communicating via Bluetooth with a smart mobile device.
• Implemented a digital filter within the cuff for signal processing, replacing traditional analog circuits.
• Designed a user interface for Android and iOS operating systems for device control and data display.
• Conducted tests on 18 patients and 20 healthy individuals under physician supervision.

Main Results:

• The developed wireless blood pressure device demonstrated high accuracy.
• Achieved an average accuracy of 93.52% in measurements for sick individuals.
• Achieved an average accuracy of 94.53% in measurements for healthy individuals when compared to a sphygmomanometer.
• The smart mobile device interface functioned effectively for control and indication.

Conclusions:

• The wireless blood pressure measuring device integrated with smart mobile technology is a viable and accurate solution.
• This mHealth approach offers a promising alternative for convenient and accessible blood pressure monitoring.
• The use of digital filtering and mobile integration enhances the performance and usability of the device.
