Resumen de DIY diagnostics for world's poorest
For many people in developing countries, being creative with what little they have is part of daily life. Now that frugal approach is being applied to medicine and science, with the advent of devices made from barebones materials that are easy for anyone to assemble and repair on their own. Groups like Massachusetts Institute of Technology's Little Devices lab are hacking common tools such as bicycle pumps to make nebulizers for medication, for instance. In a field trial in Nicaragua, they have begun testing an autoclave for sterilizing medical equipment. Built from a pressure cooker, it uses the insides of snack wrappers as reflectors to concentrate solar rays for power. Another ingenious technology is Foldscope, a paper microscope designed by Manu Prakash of Stanford University, California, that costs about 50 cents to produce. The pattern is printed in several die-cut pieces on a single sheet of stiff, water-resistant paper. The color-coded pieces make the microscope easy to put together in a few minutes without needing to read instructions.
