Students Design Low-Cost Surgical Lamp for Developing Nations

05.05.2009
Engineering students have developed a low-cost, battery-powered surgical lamp to be used in developing nations where electricity isn't reliable.

Earlier this month, members of Michigan Health Engineered for All Lives, or M-HEAL, sent their prototype lamp to Uganda where it will undergo testing.

"The power grid is very unreliable in developing countries," said Stephen DeWitt, co-founder of M-HEAL and leader of the team that built the lamp. "If you're in the middle of surgery and the lights go out, that's very bad news for the patient. We don't think that's acceptable. We're building a low-cost alternative that has a lot of the performance of a full-scale, Western surgical lamp." DeWitt is a graduating senior in engineering physics in the College of Engineering.

The lamp is made of a pie pan, a bike brake, a joint from a car rearview mirror and light-emitting diode flashlight components. It is affixed to an adjustable pole on wheels. DeWitt estimates it would cost around $300 to build, now that the team has developed the blueprints. That's more than $500 less than the closest competition.

"The lamp is really exciting because it's M-HEAL's first design project," said Julia Samorezov, a graduating senior in biomedical engineering and co-founder of M-HEAL. "These guys did a great job. They focused on what resources are available in the developing world and how to use local materials in a sustainable way."

M-HEAL's primary mission is to design, build and repair medical equipment to improve access to healthcare technology in the developing world. The group regularly travels to Detroit-based nonprofit World Medical Relief to repair used medical equipment and distribute it to places across the globe. M-HEAL plans to expand into more design projects. They also intend to improve the lamp with the feedback they get on the prototype. Eventually, they hope to produce an instruction manual so that these lamps could be built where they're needed with local materials.

Other members of the surgical lamp team are undergraduate biomedical engineering students Elliot Hwang, Michael Weist, Michael Harrison and Phil Guan; biomedical engineering graduate students Carl McGill, Seth Koehler and Chris Voge; and applied physics graduate student Abigail Mechtenberg. The team's faculty adviser is Aileen Huang-Saad, a lecturer and assistant research scientist in the Department of Biomedical Engineering.

Michigan Engineering:
The University of Michigan College of Engineering is ranked among the top engineering schools in the country. At more than $130 million annually, its engineering research budget is one of largest of any public university. Michigan Engineering is home to 11 academic departments and a National Science Foundation Engineering Research Center. The college plays a leading role in the Michigan Memorial Phoenix Energy Institute and hosts the world class Lurie Nanofabrication Facility. Michigan Engineering's premier scholarship, international scale and multidisciplinary scope combine to create The Michigan Difference.

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
