Connected medical devices for telehealth: what the remote doctor actually sees

The gap between a video call and a real clinical examination is measured in data. A video call transmits a picture and a voice. Connected medical devices for telehealth transmit ECG traces, stethoscope audio, vital signs, dermatoscopic images, otoscopic images, ultrasound video, blood glucose levels, hemoglobin counts, and spirometry readings — all in real time, all integrated into a single clinical interface.

This article explains what the remote doctor actually sees when each category of device is connected to the MedConnect platform, and why this data transforms the quality of a remote consultation.

The 20+ devices that integrate with MedConnect

MedConnect natively integrates more than 20 CE-certified medical devices across 12 categories. Each device connects via Bluetooth, USB, or Wi-Fi and transmits data directly to the platform — no manual entry, no file uploads, no third-party software.

The main categories:

• Electrocardiograph (ECG): 12-lead ECG systems by Cardioline and Schiller. Bluetooth connectivity, built-in Glasgow algorithm for automated pre-interpretation.
• Stethoscope: digital stethoscopes including the Mintti Smartho-D2 (BLE 5.0, 53g) and Riester ri-sonic. Stream cardiac and pulmonary audio live to the remote doctor.
• Vital signs monitor: measures blood pressure, SpO2, heart rate, temperature. Continuous monitoring during the consultation with automatic data capture.
• Dermatoscope: Firefly digital cameras with up to 1600×1200 resolution and 15–105× zoom. Captures clinical-grade skin images for dermatological assessment.
• Otoscope: Firefly otoscopic cameras (1280×1024, 15–150× zoom). Transmits ear canal and tympanic membrane images.
• Ultrasound: portable wireless probes (convex, linear, endovaginal) with 2.4G/5G Wi-Fi connectivity. Live video streams to the remote doctor.
• Spirometer: USB spirometers for lung function testing (MIR turbine, ±16 L/s range).
• Point-of-care analyzers: glucometer, hemoglobinometer, urinalysis (Siemens Clinitek Status), blood analyzer (30 parameters).
• Fetal Doppler: Comed PRO with ±2 bpm precision and 3 MHz probe. Three display modes for fetal heart rate monitoring.
• Bladder scanner: non-invasive bladder volume measurement up to 1000 ml.

What the remote doctor sees for each device type

ECG: full 12-lead trace in real time

When the nurse places electrodes and starts the ECG, the remote doctor sees the complete 12-lead trace streaming live on their screen. The built-in Glasgow algorithm provides automated pre-interpretation — flagging potential abnormalities before the doctor reads the trace. The trace is automatically saved as a PDF in the patient record. For specialist review, the doctor can send the ECG to a cardiologist via tele-expertise with one click.

For Holter ECG analysis, MedConnect integrates with Cardiomatics — an AI-powered service that processes 24-hour recordings and returns detailed arrhythmia analysis.

Stethoscope: live cardiac and pulmonary audio

The connected stethoscope transmits amplified audio directly to the doctor's headphones or speakers. The doctor hears heart sounds (S1, S2, murmurs) and lung sounds (crackles, wheezes, diminished breath sounds) in real time. Each auscultation is recorded and archived in the patient record for longitudinal comparison. The eMurmur AI module can analyze recorded heart sounds for additional cardiac screening.

Vital signs: continuous dashboard

Blood pressure, SpO2, heart rate, and temperature appear on the doctor's screen as a live dashboard. Values are automatically logged in the patient record with timestamps. Threshold alerts notify the doctor of abnormal readings during the consultation.

Dermatoscope and otoscope: high-resolution clinical images

The nurse captures images with the dermatoscope or otoscope. The doctor sees them instantly at full resolution — zooming, panning, and comparing with previous images from the same patient. Images are archived automatically.

Ultrasound: live video feed

The portable ultrasound probe connects via Wi-Fi and streams live video to the doctor. The doctor guides the nurse's probe positioning in real time. This is particularly valuable for cardiac assessment, abdominal examination, and obstetric monitoring in remote locations.

CE certification: what it means for procurement

Every device integrated with MedConnect carries CE marking, certifying compliance with European medical device regulations. For international procurement:

• CE marking is recognized in the EU, EFTA countries, and widely accepted internationally
• It certifies that the device meets essential safety and performance requirements
• It covers electromagnetic compatibility, biocompatibility (where applicable), and clinical evaluation

All devices are distributed by Promotal, part of Groupe Eloi — a French medical equipment manufacturer with 97 years of experience, headquartered in Gennevilliers with manufacturing in Ernée, France.

MedConnect Hub: how all devices connect

In a traditional setup, each device needs its own software, its own driver, and often its own PC. The MedConnect Hub eliminates this complexity. It is a compact bridge (under 15cm × 15cm × 5cm, VESA-mountable) that:

• Connects all devices via 5× USB ports and Bluetooth 5.0
• Provides gigabit Ethernet and Wi-Fi 5 connectivity
• Runs a hardened Linux OS with Docker containerization
• Receives over-the-air updates without on-site IT intervention

For international deployments where IT infrastructure is minimal, the Hub provides a self-contained, maintained computing platform that connects the entire device ecosystem.

Synchronous vs asynchronous device data

In synchronous (live) mode, device data streams to the doctor in real time. In asynchronous (store-and-forward) mode, the nurse performs the examination, data is stored locally on the device or Hub, and uploads when connectivity allows. The data format is identical in both modes — the doctor reviews the same ECG traces, images, and vitals whether received live or delayed.

In Ivory Coast, the asynchronous model with connected medical devices enabled screening of 150 patients per day. In New Caledonia, over 1,500 teleconsultations used synchronous device data over satellite and 4G links.

FAQ

How many devices does MedConnect support?

More than 20 CE-certified devices across 12 categories: ECG, stethoscope, vital signs, dermatoscope, otoscope, ultrasound, spirometer, point-of-care analyzers, fetal Doppler, bladder scanner, dental camera, and colposcope.

Do devices require special software or drivers?

No. Devices connect via Bluetooth, USB, or Wi-Fi directly to the MedConnect platform or MedConnect Hub. No third-party software installation is needed.

Can device data be sent to a specialist for review?

Yes. From the patient record, the doctor can send any device data (ECG traces, images, vitals) to a specialist via the tele-expertise module, integrated with Omnidoc (110,000+ specialists).

Are the devices portable enough for home visits?

Yes. The complete telemedicine kit weighs approximately 8 kg and fits in a carrying case. For lighter deployments, the telemedicine backpack weighs under 3 kg with stethoscope, vital signs monitor, and oximeter.
