Health Gateway Telemedicine platform for healthcare and wellbeing solutions
Health Gateway Coagulation EMG Blood Glucose Blood Pressure Body Weight SpO2 Spirometry ECG wireless data transfer secure connection ehit s Health Gateway is a vital signs monitoring system, which transfers the measured data to the health care provider in a fast, secure and reliable way
Virtual link between patient and health care professionals
Electrocardiography 100 years ago
Electrocardiography today 36 mm 36 mm precision bioamplifier support for integrated or external electrodes resolution of 12 bits adjustable sampling rate (100-5000 samples/sec) li-ion rechargeable battery Bluetooth microprocessor 1 MB flash memory signal preprocessing programmable digital filter
Application case erescue
erescue Telespro Rescue Covering GORE TM Rescue Blanket laminate protects patients against severe weather conditions, cold, moisture and wind, and bacteria penetration simplifies rescue process improves the patient s safety Typical applications emergency ambulance rescue helicopter coast guard rescue ski centres
erescue SpO2 sensor ECG connectors Blood pressure cuff PDA device displaying vital signs
erescue The mobile device collects data directly from the measurement devices ECG HR 70 %SpO2 98 SYS/DIAS 140/90 GSM/GPRS Secure communication Clinic platform The Health Gateway Mobile Platform collects the measured data wirelessly and displays the data in a clear format 3-lead ECG Measured data are immediately available for analysis Blood Oxygen saturation Feedback and/or further instruction can be quickly sent directly to the mobile device of the paramedics Blood pressure
Application case HRV monitoring and interpretation
HRV monitoring and interpretation The wireless sensor continuously registers the ECG signal without interfering with patient s everyday life The mobile phone wirelessly collects the ECG data and forwards them to the health care professional for analysis The health care professional can view the ECG data in real time regardless of patient s location and send and immediate feedback
HRV monitoring and interpretation The mobile application logs in to the server by following an authentication procedure Data are safely stored into a centralised server HTTPS TCP/IP SSL GPRS/GSM/3G Internet Bluetooth The ECG device wirelessly sends the ECG signal to the paired mobile phone The remote workstation also follows an authentication procedure and makes use session keys for ensuring data protection
HRV monitoring and interpretation Healthy subject 30 years old µ: 13.6 Scattered dots in a homogeneous area
HRV monitoring and interpretation Healthy subject 75 years old ST depression(+) R-R interval too regular µ: 0.0004 Dots concentrate in a very small area
HRV monitoring and interpretation Subject with breast cancer 60 years old ST depression(+) µ: 0.36 Scattered dots in a narrow and tall area
HRV monitoring and interpretation Apparently healthy subject 70 years old arrhythmias atrial fibrillations µ: 10.6 Scattered dots in a wide and low area
Conclusions
Conclusions Compact sized, easy to be carried along capture important information that would otherwise be missed Dual operating mode online transmission of real time ECG data batch transmission of all or part of the registered data Local data processing only relevant data need to be transferred Bidirectional communication feedback from professionals Based on standard technologies easy integration with existing systems
