News Brief
In Malawi’s Mzimba district, 22-year-old biomedical engineering student Ranken Chisambi is transforming healthcare in rural clinics. Witnessing patients suffer due to hospitals lacking basic equipment, he invented a low-cost, portable compression therapy device for conditions like DVT and lymphedema, and a Neo Smart Baby Incubator for premature infants. Using locally available materials, his devices cost a fraction of standard machines. Committed to homegrown solutions, Ranken plans to scale, patent, and mass-produce his innovations, proving that local ingenuity can address pressing healthcare challenges.
As a boy in Chamhanya Gondwe village in Malawi’s Mzimba district, Ranken Chisambi watched patients struggle because hospitals lacked basic medical equipment. Simple problems, like swollen legs or premature babies needing care, often went untreated. Today, at 22, this final-year biomedical engineering student is determined to change that.
He says, “I saw how hospitals often couldn’t help patients with conditions like swollen legs or premature babies. That inspired me to use technology to solve real problems in Malawi.”
His most promising innovation is a low-cost, portable compression therapy device. It helps patients with varicose veins, lymphedema, and deep vein thrombosis (DVT) by gently squeezing and releasing their limbs to improve blood flow.
He says, “The machines hospitals usually use cost thousands of dollars. I wanted to design something affordable, simple to use, and maintainable with local skills.”
Using locally available materials, affordable electronics like air pumps, solenoid valves, pressure sensors, and a microcontroller, Ranken built the device. He even 3D-printed the casing, bringing the total cost down to about USD 300 — far below standard commercial machines.
He also created a Neo Smart Baby Incubator, which automatically controls temperature and humidity for premature infants, and a heart monitoring device that alerts caregivers to irregular heart activity.
He says, “These devices are designed to be simple, portable, and easy to use in rural clinics, even where there might be no technical staff. We want to show that local innovation can solve local problems.”
Despite limited funding, scarce mentorship, and the demands of his studies, He has remained committed to his vision.
He says, “It’s a challenge to balance school with my projects, but I plan my time carefully and integrate what I’m learning in class. That way, my education fuels my innovation.”
He is now preparing to take his compression therapy device further. He plans to patent it, get regulatory approval, and partner with hospitals, investors, and government agencies to mass-produce it locally.
He adds, “If we can scale these technologies, we can reduce suffering, lower treatment costs, and show that homegrown solutions can work. We don’t have to wait for help from outside. We can innovate here, for our people, with our resources.”
Looking ahead, he dreams of becoming a medical device developer and entrepreneur, while creating opportunities for other young innovators in Africa.
With his persistence, creativity, and determination, Ranken Chisambi is proving that one young person, driven by local insight and innovation, can make a real difference in healthcare.
