blood pressure monitor portable

[tinhnv92]

Hi everyone, i am working with blood pressure monitor portable ,

I had finished analog circuit from sensor MPX5050 , then i want to test this circuit , but i don't have no idea , how to generate a blood pressure signal ! ,

can you help me ! Thanks  ,

here is my ciruits

Hello a b,

You’d need a blood pressure cuff. The pressure sensor would measure the pressure change in the cuff:

In the above image you can see a blood pressure cuff with a mechanical pressure gauge, instead of that you would connect P1 of the MPX5050.

Please take a look at “Ankle-Brachial Index” image in the following page for detailed information on using a blood pressure cuff:

If you’re only simulating the circuit, you’d need to generate a signal like the one shown in the following page:

I’d recommend you to run some test in Matlab or Octave, you can generate such signal by adding sinusoidal signals of different frequencies.

You could also download an artificial biomedical signal generator from the following page from OhioLINK ETD Center:

Hope it helps!
