Why the Future of Heart Health is ‘Cuffless’

Dr Keith Joe spent 25 years in the emergency room watching a recurring story play out. It wasn’t just the patients arriving in crisis; it was the “spiderweb” of wires and tubes that trapped them once they were admitted.

“The more they were monitored, the less comfortable they would get,” Dr Joe recalls. “They were stuck with all this equipment on their chest, arms, and hands. They couldn’t get out of bed, couldn’t go to the toilet, and they definitely couldn’t get a decent night’s sleep.”

For Joe, an emergency physician, the irony was clear: the very tools used to save lives were making the experience of being a patient worse. But there was a deeper, silent problem lurking outside the hospital walls.

Hypertension—the “silent killer”—affects 1.4 billion people globally. In Australia, the statistics are sobering: one in three adults has high blood pressure, and half of them don’t even know it. Despite decades of access to traditional blood pressure machines using a cuff around the arm, the rates of stroke, dementia, heart attack, and kidney failure linked to hypertension continue to rise.

Now the Founder and Managing Director of Zaplutus Health, Dr Joe is ditching the bulky blood pressure cuff for something more elegant. His solution, Ora Connect, is a “peel-and-stick” wearable that monitors blood pressure and vital signs wirelessly and continuously.

To explain how a tiny patch on the chest can measure blood pressure without the squeeze of a cuff, Dr Joe uses a surprisingly simple analogy: a summer storm.

“When you have a thunderstorm, you see lightning and then you start counting—one thousand and one, one thousand and two—until you hear the thunder. You know the storm is two kilometres away,” he explains.

“We do exactly the same thing. There’s an electrical activity which triggers the heart to squeeze, and then blood is ejected. We detect when that blood travels from one part of the body to another. The delay tells us the driving force—the blood pressure.”

The technology isn’t just a passion project; it’s the result of a decade-long “dream combination” between clinical expertise and engineering. Dr Joe partnered with Professor Mehmet Yuce, an IEEE Fellow with over ten years of research in cuff-less blood pressure research.

While the market is flooded with consumer-grade smartwatches that track heart rates, Zaplutus is aiming for a different league. Ora Connect is designed to be a regulated medical device, providing “hospital-grade” data over hours and days that doctors can actually trust for diagnosis and treatment.

As Zaplutus Health opens a $2.5 million capital raise, the goal is clear: secure TGA approval and get the device into the hands of GPs, cardiologists, and remote communities.

For a country like Australia, where the “tyranny of distance” often dictates health outcomes, the implications are massive. Dr Joe envisions a future where a device can be mailed to a patient in a remote town, allowing for high-level monitoring via telehealth that was previously impossible.

“We want to make hospitals safer by using AI to predict who is going to become unwell before the human eye can see it,” says Dr Joe. “But we also want to move care outside the hospital walls.”

In a world where healthcare systems are under “massive pressure,” Zaplutus Health isn’t just offering a new gadget—it’s offering a way for patients to breathe, move, and sleep again, all while staying safely under their doctor’s watchful eye.
