I want to make a blood pressure cuff that can be controlled and managed with a mobile app

Hardware:
- Cuff size 22-52 (for upper
arm/upper thigh)
- Oscillometric method with
automatic inflation
Controlled pressure release
valve (cuff enclosure/case,
belt, pump)
- Ability to set rate of inflation
(range from 40 to 250
mmHg )
Ability to set the duration of
inflation (range from
seconds to 60 minutes)
Software:
- Turn on/off device.
- Display: systolic BP, diastolic BP, HR
- Measuring blood pressure using the Oscillometric method
- Setup
a) Time: 1) cuff deflation time
2) cuff inflation time
3) deflation post-cuff inflation time
b) Pressure:
- Rate of cuff inflation ( manual entry and auto-calculated based on the measured blood pressure (w
program options such as 30-50 mmHg above systolic)
- Duration of inflation for a sec to 60 with program options on duration, with inflating cuff if the pressure
drop plus 10 mmHg)
- Charging (c Cable/rechargeable)

OLED Display - Small OLED display - System on/off, Sensors off/on, Battery off/on, Bluetooth connected, cuff inflation/deflation
Multi-tasking
Bluetooth

Connecting cuff/sensors to
smartphone – system operation
and data transfer

- Option to pair 1-4 BP devices simultaneously
- Received all data from the system and transferred it to the smartphone app
- Checking errors/security of data

PPG/IR sensors HR, HRV, O2, velocity. Heat,
temperature, and humidity
PPG Sensor 1 and Infrared Sensor 2

- BP measurement at baseline/Inflation/deflation

GSR/EDA sensor GSR/EDA sensor - BP measurement/Inflation – measure for a duration of BP measurement/inflation (up to 60 min)
Gyro Sensor Gyro Sensor - BP measurement/Inflation – measure for a duration of BP measurement/inflation (up to 60 min)
Smartphone
control/Monitor

App with secure login, access to BP cuff and system, with the setting, receive data for multi-
tasking Bluetooth
