AustraliaThe Challenge
Checking blood pressure, oxygen level, heart rhythm and blood sugar usually takes several separate devices: a cuff, a finger clip, a finger-prick meter, and ECG leads or patches. That is awkward for daily use, and hard on people who need regular monitoring at home.
Doctors and carers also need to see those readings remotely and be told when something is wrong, without the patient having to do anything technical.
The Solution
The device is a lead-less, patch-less wearable worn on the fingertip. It estimates heart rate, respiration rate, systolic and diastolic blood pressure, SpO₂ and blood glucose, and monitors ECG and obstructive sleep apnea in real time.
It pairs with a companion phone app over Bluetooth: secure login, live vitals, a month of history and alerts for abnormal readings. Data syncs securely to the cloud, so doctors and nurses can monitor several patients remotely, and an AI health assistant answers health-related questions and helps with assessment.
System Architecture
- Step 1Wear it on a fingertipA lead-less, patch-less sensor reads vital signs from the fingertip.
- Step 2See it on the phoneReadings stream to the app over Bluetooth, with alerts if anything is abnormal.
- Step 3Share with the doctorSecure cloud sync lets doctors monitor remotely; an AI assistant answers questions.
