Omron Automatic Blood Pressure Monitor TEARDOWN!

There is a weak point in the Omron Ultra Premium Automatic Blood Pressure Monitor (Model: HEM-790ITCAN). It is the blood pressure cuff, which tends to form a leak well before the main electronic unit fails. Replacement cuffs cost almost as much as the entire unit, so it's not worth replacing. Trying to find the leak to repair it destroys all the fabric around it! In this video we explore how the BP monitor works, locate the air pump, solenoid valve and look inside the pressure sensor. By seeing the tubing and path that air takes, we can understand how the BP monitor analyzes the pressure curve to detect when it has peaked out, and how it listens for pulsations (first systolic and then diastolic) as the cuff deflates to figure out your blood pressure!

Awesome video dude! That’s exactly what I’ve been doing all the way up since my high school years! Satisfying my curiosity you know 😅

Thanks for watching! It's fun taking things apart and learning how they work!

Since manufacturers hides their design it is a must to tear down the unit to learn the principles behind it and knowing how to make the necessary repairs.

That's what this channel (and others) are all about. Opening and reverse-engineering and understanding how things are built is fun and educational, and practical too when you need to repair something!

What are you doing to your cuffs that they keep leaking? Are you putting serious creases in them repeatedly? I've seen these cuffs last almost twenty years.

[@devhackmod]

There is a good chance cuffs that were made 20 years ago were of better quality material, so they have lasted. Lately they have been worsening quality. I am using them as directed, not bending them, they are lightly used. I don't know why they leak but when they do it's cheaper to buy another entire unit than try and replace only the cuff. Repairing the cuff is also a mess because it's all wrapped inside of fabric so to get it out and put it back in properly is not easy or practical considering the time involved.

The cuff usually punctures before the electronic unit ever fails... but they rarely (if at all) sell the cuffs at a price that justifies buying it alone.

I bet that blood presure machine is done for 😂😂😂😂

[@devhackmod]

Yes now for sure it is!
