Vacuum-Assisted wound care (VAC) is effective for treating complex wounds, but is hardly available in low-resource settings. An affordable, portable and safe VAC device was developed to treat patients with chronic and complex wounds: the Wound Care (WOCA) Pump. The WOCA safely controls the pressure accurately (+/- 10%) between -70 and -125 mmHg for...

Water pumping systems driven by renewable energies are more environmentally sound and, at times, less expensive alternatives to electric- or diesel-based ones. From these, hydro-powered pumps have further advantages. Nevertheless, these seem to be largely ignored nowadays. More than 800 scientific and nonscientific documents contributed to assemble...

In low- and middle-income countries (LMIC), diagnostics are not always available in remote areas. Hospitals and healthcare centres are often too far from the community, and waiting times are up to a few hours even for relatively simple procedures. Moreover, travelling to the healthcare centre and taking the diagnostic test is frequently unaffordabl...
