Medical Innovations: Eyewear
New inventions and discoveries continuously change the face of healthcare across the globe. Smallpox vaccination, penicillin,
in vitro fertilisation, magnetic resonance imaging - the list is long.
But what's next? Do it yourself spectacles, build your own toilets, social media, a biobank of health data?
These four ideas were voted on at last month's BMJ Innovation Expo conference in London, where a panel of experts debated
which one is most likely to make the biggest impact on healthcare by 2020.
Discover the winning idea by reading Sabreena Malik's round up of the day.
This first film shows the work of Josh Silver, inventor of the world's first self adjustable spectacles, which he hopes will
bring corrective eyewear to those who need it for about £1 (€1.1; $1.6) - and without the need for eyecare professionals.
Shit matters
Community led total sanitation may not sound like the most cutting edge medical science, but the potential impact of this initiative is huge.
Contact with faeces spreads human disease, and this technique helps villagers around the world understand how the practice of open defecation means that they're, literally, in the shit.
You can hear more from Kamal Kar, inventor of Community Led Total Sanitation on the BMJ podcast
Biobank
When it comes to doing epidemiological studies, numbers matter. We find out about the UK's biobank - a project to collect information and samples from 500,000 volunteers, which should help scientists look for links between lifestyle and health.
Gentamicin calculator
Gentamicin is an antibiotic that is widely used in hospitals, but calculating the correct dose to give to patients can cause problems for doctors.
One junior doctor, Imran Qureshi, used his computer science background to create a simple to use gentamicin calculator.
Tournistrips
Tourniquets are used to make it easier to take blood samples from patients. If they are used on multiple patients there is a risk that they could transmit a potentially harmful infection.
There are many disposable tourniquets available, but this group of junior doctors found that they were being re-used. They invented a new single-use disposable tourniquet that could help prevent hospital acquired infections.
Twitter epidemics
During the swine flu pandemic, google showed that it was able to track the spread using the searches that it's users were making. In this video Dr Patty Kostkova shows her work using twitter - and how the data from that could be used to track future epidemics.
