The USB powered Tele ECG machine is portable 12-lead ECG device suitable for real-time cardiac monitoring. It records surface potentials associated with the electrical activity of heart, from all the leads simultaneously. A USB cable connects the device seamlessly to either a mobile phone via OTG (On-The-Go) technology or to a PC/laptop. An application software captures the ECG signals and generates the ECG report in pdf format, enabling easy sharing via WhatsApp, email, or other file-sharing applications.

Being USB powered, the device does not need an on-board battery and associated charging circuitry, thereby reducing the Bill of Materials (BOM) cost and simplifying maintenance, as compared to a Bluetooth based Tele ECG machine. In compliance with the medical device standard IEC 60601-1, the ECG device incorporates ground isolation between its internal circuitry and the external/USB ground, to provide patient safety and interference free operation when the device is connected to the mains-powered PC or laptop.

1. Simultaneous acquisition from all 12 ECG channels.
2. Draws power from the USB, does not require charging of the device.
3. Low BOM cost, compact and lightweight
4. Digital ECG report generation in PDF format, for easy sharing and digital archiving for future reference.
5. Flexible report formats: 6×2, 3×4 simultaneous/sequential reports with long Lead-II on A4-size paper.
6. Built-in test signal generator for real-time health monitoring of the device.
7. Ground isolation in compliance with the medical device standard IEC 60601-1
8. Versatile applications in primary health clinics, mobile ambulances, personal health monitoring, city hospitals and more.

1. Primary Health Clinics & Multi-Specialty Hospitals – Enables quick and cost-effective ECG diagnosis in rural and urban healthcare centers.
2. Mobile Ambulances & Emergency Services – Provides real-time ECG acquisition in transit for early diagnosis and prompt medical intervention.
3. Personal Health Monitoring – Allows individuals with heart conditions to monitor their ECG at home and share reports with healthcare professionals.
4. Military & Defense Medical Units – Ensures cardiac health monitoring in field hospitals and remote deployments.

The USB powered Tele ECG machine has been developed, evaluated for its functional requirements using simulator and found to meet the desired specifications. The application software acquires ECG data from the Tele ECG device through USB link and provides GUI for display/storage. The Android App was installed on few smartphones from four different manufacturers (Samsung, Google, Vivo & CMF by Nothing) running Android versions 13, 14, & 15 and tested for its functional requirements.

The technology of USB powered Tele ECG machine is being offered on an as-is where-is basis. The technology licensee shall be responsible for its manufacture, device enclosure design, testing with latest smartphones, making changes in Android App, if required, and qualification tests/certification, if desired, before launching the product in market.
