Train on simulators not patients
A young Adelaide engineer has
developed a simulator to help health professionals learn how to properly perform
the common ‘pen torch’ examination of the eyes – an essential test for signs of
brain dysfunction.
The simulator, known as EyeSim
and designed by Timothy Nelson of Flinders University, will allow trainees to
practise without distress to real patients - in the same way that pilots
practise using flight simulators.
“Although the “pen torch” test
is one of the most common clinical examinations, the procedure involves complex
interpretation of what can be very subtle symptoms,” Tim says.
“Hospitals presently pay
upwards of $250,000 for a high tech manikin, which will simulate all sorts of
human functions, but the eyes are fixed and completely non-responsive to light,”
says Tim.
“The current teaching method
relies on using textbooks, in conjunction with practice on human patients.”
“EyeSim offers the advantages
of a realistic constriction and dilation of the pupils, and the ability of the
eyes to follow a moving object when illuminated with a pen torch.”
“EyeSim will allow educators to
vary the complexity of a situation to suit the level of a given student. The
instant feedback and repeatability of simulation has been shown to improve the
standard of learning that students achieve.”
EyeSim is now being further
developed with a view to commercialisation and hopefully inclusion in healthcare
curricula worldwide.
Tim is one of 13 Fresh
Scientists presenting their research to the public for the first time thanks to
Fresh Science, a national program hosted by the State Library of Victoria and
supported by the Federal and Victorian governments, British Council and New
Scientist.
One of the Fresh Scientists
will win a trip to the UK courtesy of the British Council to present his or her
work to the Royal Institution.
Filming and photos of
the simulator and patients can be organised.
