Lower endoscopy

Upper endoscopy

Capsule endoscopy

• Photographic capsule

• Collect 2 images per second

• Moves by peristalsis

• Images are collected and stored for later download

• Capsule “working life” ranges 8-10hrs

• Capsule passes from body naturally

• Specific to examination of the Small bowel but other wireless device that exam remainder of GI tract

1) Precheck up to see patient are eligible to take capsule endoscopy 2) Patient are required to fast for 12 hours before taking the capsule3) Patient are mounted with antenna on the abdomen4) Patient swallow the capsule5) Patient bring back the data recorder to workstation for review the images/video

A recent trip to NUH

M-Health

• M-Health uses mobile devices and/or communication networks for the provision of health services

• Monitoring of health data

• Three major dimensions: battery life, device capabilities/functionality, size/aesthetics

Basic Monitoring (1)

• ECG, heart rate, respiration rate, activity level, blood pressure, weight, blood glucose

• Remote monitoring of cardiac arrhythmias

• Benefits

– Reduced re-admissions, shortened hospital stays, improved clinical outcomes

Basic Monitoring (2)

• Leading health apps do not monitor anything related to menstruation and reproductive health of half the world’s population

• Menstruation patterns can reveal health problems– Premenstrual syndrome– Premenstrual dysphoric disorder– Polycystic ovarian syndrome– Menorrhagia– Hysterectomy

• Other reasons for tracking– functionality of contraceptive

methods– planning work and leisure activities

• Basal temperature as indication for stage menstrual cycle and ovulation

Advanced Monitoring

• Portable test kits + smartphone camera

• Molecules to detect

– Influenza A

– Vitamin D (mood, anxiety, sleep quality)

– C-receptive protein (inflammation)

vs.

Scale Effects

In biological molecule analysis, reduction in dimensions helps shorten analysis time

This is further compounded by parallelization

M-Health Cost Savings

• In Singapore, M-Health can save health costs by S$3 billion per year– By comparison, venture capital in M-Health reached ~

US$1 billion (2013) in the US• In the EU, savings of €99 billion in 2017

– Fewer complications: doctors and paramedical staff could save 472,000 doctor days

– Other economic costs: worker absenteeism, early retirement costs

New Ways of Powering (1)

New Ways of Powering (2)

Temporary Biofuel Cell Tattoo

• Electricity from sweat

• Can be twisted and stretched

• Chemically generates electricity

Currently 5 to 70 µW/cm2

New Ways of Powering (3)

• Fibre-based nanotechnology generate electricity via piezoelectric effect

• Textile fibers covered with zinc oxide nanowires

• Nanowires generate electricity when stretched

• 6mm2 generates about 20 mV, 0.8 µA (2.5 mW/mm2)

New Ways of Powering (4)

• Implantable hydroelectric generator

• Heart generates about 1-1.5 W of power

• About 1mW power available for devices e.g. Pacemaker requires 10 µW

Conclusions

Entrepreneurial Opportunities

Conclusion• Advances in electronic components, biological

molecule analysis, batteries signal the dawn for the next generation of wireless healthcare– New medical procedures (endoscopy)– Greater control of medicinal release – Digitizing our healthy habits (digital pill)– Strengthening patient/doctor dialog (M-

Health)• Greater confidence to both patients and

healthcare professionals• Better integration

– Diagnostics and procedures– Medication– Payment

Examples - Preventice

• Remote monitoring of cardiac arrhythmias via algorithm • Doctors monitor key biometrics

– Reduced re-admissions, shortened hospital stays, improved clinical outcomes

• Components: bandage patch with battery and monitor sensor, mobile device

• Data collected: ECG, heart rate, respiration rate, activity level, blood pressure, weight, blood glucose

• Cloud-based platform collects real-time data from the mobile device• Physicians then review data• Support for numerous device connection types: cellular/smartphone, wi-

fi, Bluetooth

M-Health Cost Savings (1)

• Traveling to a central lab for testing: $10 per test• Also considering indirect cost of taking 0.5 day off to do testing:

$200• Transportation cost: $10• If 10 tests are needed a year, it will cost $2200 per year per patient• If the testing cost can be halved, and test can be done at home, in

Singapore, this can save $3 b per year (assuming 1.5 million people needing tests)

• By comparison, venture capital in M-Health reached $900 million (2012), about $1 billion (2013) in the US

M-Health Cost Savings (2)

• Savings of 99 billion EUR in the EU in 2017• mHealth can help 9.4 million regular users at risk of developing

chronic diseases to expedite diagnosis• 815,000 patients can successfully detect chronic diseases early• These patients could avoid complications and seek medical

attention earlier, reducing the need for hospitalization and saving 3.7 billion EUR in treatment costs

• Doctors and paramedical staff could save 472,000 doctor days by having to treat fewer complications

• Chronic diseases could lead to 718 billion EUR in lost wages in 2017• Healthcare cost savings as a result of improving lifestyles, reducing

risk of chronic disease, saving of hospital and doctor days, healthcare providers staying informed, reducing worker absenteeism, and avoiding early retirement costs
