  1. ITU Workshop on “E-health services in low-resource settings: Requirements and ITU role” (Tokyo, Japan, 4-5 February 2013) BAN Portable Clinic towardAffordable Healthcare M2M Service Masahiro Kuroda Manager, Standardization Promotion Office, National Institute of Information and Communications Technology marsh@nict.go.jp

  2. Epidemic of Obesity Communicable ? • Yes and No • Global status report on noncommunicable diseases (NCD) 2010 This report … particular attention … in low- and middle-income countries, which … bear nearly 80% of the burden from diseases like cardiovascular disease, diabetes, cancer and chronic respiratory diseases. The health consequences of the worldwide epidemic of obesity are also addressed. A large percentage of NCDs are preventable through the reduction of their four main behavioural risk factors: tobacco use, physical inactivity, harmful use of alcohol and unhealthy diet. (“Forward” from Dr Margaret Chan, Director-General, World Health Organization)

  3. Obesity: Fat Burning with Joy Mobile phone vibrates when enter aerobic-exercise state Body Area Network (BAN) Glimpse fat –burn amount Beautiful posture From Assoc. Prof. , Masatsugu Niawayama, Shizuoka university • Tissue oxygen saturation (StO2) is used to know whether entered aerobic-exercise state • Measure de-oxidationized hemoglobin / oxidized hemoglobin by StO2 sensor • Compute fat-burn grams from consumption calorie by 3-axis accelerometer when entered aerobic-exercise state

  4. Obesity: Essential Amino Acids Wooden bucket theory Balance in Essential amino acids Cannot use for protein composition! Cannot use for protein composition! Energy pooling as fat histidine isoleucine leucine lysine threonine methionine From Prof. Osamu Tochikubo, Medical School, Yokohama City University Nutritive value is decided by lysine and other excessive amino acid is accumulated as discharge or fat

  5. Preventive Medicine • Prevent lifestyle-related illnesses for incipient and healthy people Hypertension(H), Abdominal obesity(O),Glucose intolerance(G), Lipidemia(L) and so on Living environment change … Alcohol(A) Smoking(S1) Salt intake(S2) Saturated fat(S3) Stress(S4) Sleeplessness(S5) Lack of Exercise(E) and so on Lifestyle-related illness Lifestyle irregularity From Prof. Osamu Tochikubo, Medical School, Yokohama City University

  6. Feedback Loop in Preventive Medicine General medical checkup Health industry Association of preventive medicine Ubiquitous sensing Analysis bank Hospital Sensor selection Acute care hospital Body Area Network (BAN) Meal delivery industry Nutritional supplements or exercise instruction From Prof. Osamu Tochikubo, Medical School, Yokohama City University

  7. The BAN Standard IEEE802.15.6 First Medical BAN published in 2012 1 common MAC with 3 PHYs PHY NB Media Access Control (MAC) PHY UWB PHY HBC From 15-11-0826-01-0006-ieee-802-15-6-tutorial

  8. IEEE802.15.6: Frequency Band Quality of Service is ensured IEEE802.15.6 Wireless LAN,ZigBee, Bluetooth2.4GHz

  9. IEEE802.15.6:Strict Security Enforcement Encrypted beacon

  10. IEEE802.15 6:Priority Control Top-priority data transfer for emergency data

  11. IEEE802.15.6:Low Power Consumption Peak current 20mA Margin of processing in a sensor Flexible processing in a sensor by low peak current 10mA Bluetooth Low Energy IEEE802.15.6NB Rechargeable battery (Maxell CLB2032) From 15-11-0826-01-0006-ieee-802-15-6-tutorial.ppt

  12. IEEE802.15.6:Secure SAR Level • Protection from Radio Wave Environment • SAR(Specific Absorption Ratio) is less than 2 W per every Kg • Average power less than 20mW is outside of this limitation • Narrow Band (NB) • Designed at 1mW or less in ISM, Medical telemeter, and specific small electric power bands • Ultra Wide Band (UWB) • Below the allowable noise level (less than -41.3dBm/MHz< 20mW) • Human Body Communication • Weak radio level (<<20mW) *http://www.tele.soumu.go.jp/j/sys/ele/body/protect/index.htm

  13. Portable Clinicby Kyushu U. and Grameen • Kyushu University and Grameen Communications prototyped an affordable “portable clinic” and experimented in villages and cities, Bangladesh • Confirm functionalities and usability of the system • NICT and the QoL-SN council provide BAN-based portable clinic functions for the experimental use

  14. BAN Portable Clinic Model (Epidemiologic study) Remote medical help center Remote database Diagnosis and prescription Point-of-care medical examination and remote diagnosis B-Logic Examinees Cellular/Internet Blood pressure Blood ,Urine etc Use health-check devices for automatic categorization Portable health clinic management Non-invasive medical devices/sensors Blood test Urinalysis Paramedics

  15. B-Logic • Red: Emergent -Telemedicine + Encouragement to visit clinic • Orange: Affected -Telemedicine Yellow: Caution-Provide a leaflet about health care in Bengal • Green: Normal Designed by Naoki Nakashima, M.D., Kyushu University Hospital andKunihisa Kobayashi, M.D., Fukuoka University Chikushi Hospital

  16. Medical Checkup and Remote Diagnosis in Rural Area Bangladesh Woman doctor for Women examinees Doctor’s remote exam. Remote examinee Wait for remote Start Physical examination scene Measured data on android tablet Reg. , Interview Informed consent Tokyo, Japan, 4-5 February 2013

  17. BAN-enabled Devices and Android Terminal Android terminal BAN blood pressure BAN SpO2 sensor BAN waist meter BAN body Temperature BAN height meter BAN weight meter Open software/hardware and standard

  18. Real Technologies for BAN Portable Clinic Unstable power supply and batteries may not be charged Data transfer via cell phone may not be available Limited space/location is available in setting up the clinic User-friendly interface for examiners

  19. The QoL-SN Council is Working www.qolsn.org Promote and help in providing really usable experimental systems, such as health-check KIOSK in disaster-stricken area, BAN portable clinic and others

  20. M2M Service Platform M2 service platform ITU-T Focus Group is working on Healthcare M2M Healthcare M2M platform is an enabler of affordable BAN portable clinic because of sharing backend resources In the near future, large number of sensors are used for NCDs protection To keep Quality-of-Service, sensors require simple-and-cheap identification, such as PUF (physically unclonable function)

  21. Feedback Loops in Preventive Medicine General medical checkup Health industry Association of preventive medicine Ubiquitous sensing Analysis bank Hospital Self checkup M2Mservice platform Nutritional guidance with evidence Acute care hospital Body Area Network (BAN) Meal delivery industry Nutritional supplements or exercise instruction From Prof. Osamu Tochikubo, Medical School, Yokohama City University

  22. Conclusions andRecommendations • Non communicable diseases are common issues in the world and can be reduced by preventive medicine using easy-to-use technologies with open standards • The first medical BAN standard IEEE02.15.6 is introduced for medical/health-related devices and sensors • BAN-enabled Portable Clinic and the service is a good candidate to provide really usable functions for preventive medicine • Experimentally use open standards, provide feedbacks to the standards, and then deploy everywhere
