Methods to monitor the blood pressure
The system uses there are three methods to monitor the blood pressure:-
1. Korotkoff method,
2. Oscillometry measure and
3. Pulse Transit Time methods to measure blood pressure.
It employs a pressure cuff and pump, plus a transducer to measure blood pressure and heart rate in three phases: Inflation, Measurement, and Deflation.
It includes an LCD, selection buttons, memory recall, power management and USB interface.
Device Subsystems
1. Processor/Memory
2. User Interface
3. Sensor Interface
4. Power Conversion
1. Processor/Memory
The digital pressure measurement and heart rate are performed by the microprocessor. Measurement results are stored in Flash memory as a data log that can be uploaded to a PC
via USB.
2. User Interface
Allows the user to control the pressure measurement process and read the results on a LCD display.
3. Sensor Interface
Allows the processor to control the cuff inflation/deflation and sense blood pressure which is amplified by instrumentation amplifiers and digitized by the ADC.
4. Power Conversion
Converts input power from the alkaline battery to run various functional blocks.
Advantages
1. Efficient Pressure monitor in every second
2. It is store the pressure level in every second
3. It is less power consumptions
4. Very clear display settings to show the level of Pressure
5. The device is very small in size because in made by using Integrated Chips.
6. The device sensor is very sensitive of measuring even small changes in blood pressure in human body.
