  1. i-Med - How medical electronics will deliver patient power Noel Hurley COO, Toumaz UK Ltd

  2. Society Faces Major Health Challenges Fewer Younger People Obesity and Sedentary Lifestyle United Kingdom People Under 16 15 million 10 million People Over 65 5 million 1971 2013 2021 Source: ONS Fewer carers & lower social and health insurance income Increased prevalence and earlier onset of chronic diseases

  3. Healthcare is changing • Healthcare infrastructure was set up to manage acute illness, today 70 to 80% of the healthcare budget is spent on chronic diseases. • Better more flexible monitoring of patients • Migration of the care from the hospital to the home

  4. Patient Monitoring: Early Warning • BMJ on Early Warning Scores: 84% of patients had documented observations of clinical deterioration within eight hours of cardiopulmonary arrest” • RM Schein 1990: 70% of patients have respiration problems 8 hours before circulation stops • C Franklin 1994: 66% of patients show abnormal symptoms 6hrs before circulation stops • The doctor was warned in 25% of cases

  5. Patient monitoring today • Cable management, infection control • Care areas, patient comfort and distress

  6. Medical Body Area Networks (MBAN)a network of wireless sensors around the body • Clinical Benefits • Patient mobility and comfort • Monitoring flexibility • extending monitoring into all care areas. • Infection control • Low cost disposable monitors • Patient identification and tracking

  7. MBAN Challenges Robust wireless links Capacity for Patient and Sensor density Co-existence with other radios and networks Days of continuous use from small light weight devices (batteries)

  8. Sensium End-to-End solution Sensium Body Device Sensium Bridge Sensium Gateway Server WiFi Ethernet Cellular NSP Protocol Data & Msg Mgt Device Config Processing Processing IP Network Bridge Radio Transceiver Radio Transceiver Network Mgt Sensor Interface ECG, HR, HRV, RR, Temp, Motion (SPO2, EMG) Data Protocols Cellular Network Management Robust Network Ultra-low power Radio

  9. Low Power Challenge Zigbee & Bluetooth LE Longer battery life A generation ahead of the market Smaller lower cost battery Tx/Rx Power (mA) Lighter more comfortable body device Toumaz Voltage

  10. Sensium SoC Products Sensium Bridge Devices TZ1053 TELRAN (Low Power Radio uC) TZ1090 XENIF (Linux Apps Processor) Sensium Body Devices TZ1030 Low Power Sensium SoC TZ1031 (Low Power Sensium SoC)

  11. Future MBANs :IEEE 802.15.TG6 (MedWin) • Members: Toumaz, GE Healthcare, Philips Healthcare, Texas Instruments. • FCC new MBAN service 2360 to 2400MHz band • 2360-2390 MHz MBANS operations limited to health care facilities outside exclusion zones (indoor use only) • 2390-2400 MHz  MBANS operations permitted anywhere (all hospitals, in-home, mobile ambulances, …)

  12. Future MBAN Markets SaaS / Cloud Services Hospital Market Closed fixed networks Improved detection and intervention Greater flexibility and efficiencies Standardisation GP Budget changes 4G Networks Hospital to Home Integration with open and mobile networks Improved quality of life for chronic disease sufferers Pharma Quantitative proof of outcomes Personalised therapies Ambulatory Patient Research 2010/11 2012/13 2014/15 2016/17

  13. … and finally Biological Beta Cell Silicon Beta Cell Georgiou,P, Toumazou,C: A Silicon Pancreatic Beta Cell for Diabetes. IEEE Transactions onBiomedical Circuits and Systems, 1:39-49, 2007
