    Rice’s student-designed device to help babies breathe wins more support

    Saving Lives at Birth funds low-cost bCPAP to help newborns in respiratory distress

    HOUSTON – (July 30, 2012) – Rice University’s low-cost, student-designed device that helps newborns in respiratory distress is one of three projects nominated this month to receive a grant of up to $2 million from the Saving Lives at Birth partners to speed deployment of the technology in Malawi in southern Africa.

    Bubble continuous positive airway pressure undefined or bCPAP undefined devices are commonly used in the developed world to treat infants whose respiratory systems are underdeveloped or compromised by infection. However, at $6,000 each, the devices are often too expensive for hospitals in the developing world. The bCPAP device developed by Rice can be built for $160 and delivers the same therapeutic pressure as devices in hospitals in the developed world. Rice’s bCPAP device, a project in Rice’s Beyond Traditional Borders initiative, was developed at Rice’sOshman Engineering Design Kitchen by seniors as their engineering design capstone project in 2010.

    We are very grateful for the opportunity to continue the important work we began with Saving Lives at Birth seed funding to evaluate and implement the low-cost bCPAP device in Malawi,” said Rebecca Richards-Kortum, Rice’s Stanley C. Moore Professor of Bioengineering and director of the Rice 360°: Institute for Global Health Technologies. “Preliminary data from our clinical trial at Queen Elizabeth Central Hospital in Blantyre, Malawi, suggest that our bCPAP device can significantly improve survival for infants struggling with respiratory distress. We look forward to bringing this life-saving device to all central and district hospitals in Malawi with transition-to-scale funding.”

    Saving Lives at Birth is sponsored by the U.S. Agency for International Development, the government of Norway, the Bill & Melinda Gates Foundation, Grand Challenges Canada and the U.K.’s Department for International Development. Last year, Rice’s low-cost bCPAP device was one of 19 projects selected by Saving Lives at Birth for seed-grant funding. The device competed with more than 600 submissions. This year, Rice’s bCPAP device was among three of 14 applicants nominated to receive a larger “transition-to-scale” grant. The additional funds are intended to scale up the technology for widespread deployment in Malawi. Rice will now enter into negotiations before the award is finalized. The grants are typically worth $2 million.

    With seed funding, Rice 360° and its partners, the University of Malawi, Baylor College of Medicine and 3rd Stone Design, evaluated the low-cost bCPAP device in a clinical trial at Queen Elizabeth Central Hospital this year, developed training programs, designed a commercial prototype and held a countrywide stakeholders meeting to gather feedback on the device. With transition-to-scale funding, the team, joined by MD Anderson Cancer Center, will build on this work to implement the device in all central and district hospitals in Malawi, develop a campaign to educate mothers about bCPAP and assess the device’s cost-effectiveness. An estimated 178,000 babies could be saved each year if the device is disseminated throughout Africa, Richards-Kortum said.

    In February, original student design team member Jocelyn Brown, now a staff member at Rice 360°, was one of four representatives of academic institutions invited to the White House to present at an “Innovations in Global Health” event. Also on the original student design team were Rice alumni Michael Pandya, Joseph Chang, Haruka Maruyama and Katie Schnelle.

    “This award really validates what we’ve already accomplished,” said Brown, who helped to administer the clinical study in Malawi and will return in August to complete the work. “We’re thrilled to be able to go back and tell the doctors and nurses we’ve been working with that we’re continuing, and that we can bring bCPAP to more hospitals.”

    Earlier this month, Rice alumna Jordan Schermerhorn was on the road in Africa as the winner of a competition to travel on a reporting trip with Pulitzer Prize-winning New York Times columnist Nicholas Kristof. While in Malawi, Schermerhorn and Kristof visited Rice students who were “tasked with field-testing health technologies developed in the classroom.” In her blog for the New York Times, Schermerhorn also wrote about the clinical trial in Blantyre.

    This ‘mousetrap’ may save lives


    BY PATRICK KURP

    Special to the Rice News

    Instead of building a better mousetrap, a team of Rice University freshmen took a mousetrap and built a better way to treat dehydration among children in the developing world.

    “The goal was to regulate the amount of fluid delivered to children so we could prevent over-hydration and under-hydration,” said Melissa Yuan, a member of the IV DRIP (Dehydration Relief in Pediatrics) team and a mechanical engineering major. “It’s designed to be used in severely underdeveloped parts of the world, where conditions can be pretty primitive and they may not even have electricity.”

    The challenge that sparked the innovative design has been mentioned by physicians working in Africa since Rice’s Rebecca Richards-Kortum and Maria Oden began traveling there six years ago in search of real-world design challenges for students in Rice’s Beyond Traditional Borders program. Richards-Kortum is the Stanley C. Moore Professor of Bioengineering and director of Rice 360°: Institute for Global Health Technologies, which oversees Beyond Traditional Borders. Oden is a professor in the practice of engineering education and director of the Oshman Engineering Design Kitchen.

    “Many times physicians have mentioned to us that they would like a tool that can better moderate IV-fluid delivery to children, who are often connected to adult IV-bags,” Oden said. “In understaffed medical settings, monitoring IV-fluid delivery to patients can be a challenge. At the same time, it is of critical importance that the appropriate amount of fluid is delivered.”

    The device designed by the IV DRIP team is inexpensive; it costs about $20 to manufacture. It’s a mechanical, durable, autonomous and simple-to-operate volume regulator that uses a lever arm with a movable counterweight similar to a physician’s scale to incrementally dispense IV fluid.

    The system uses the change in torque as an IV bag is drained of fluid to set off a mousetrap-like spring that clamps the IV tube and cuts off the flow of saline solution or other prescribed fluids. Tests have shown the device dispenses fluid within 12 milliliters of the desired volume in increments of 50 milliliters.

    “We knew we needed something simple and reliable, not high-tech or terribly sophisticated,” Yuan said. “There’s nothing digital about it, nothing electrical or fancy.”

    The team includes chemical engineering major Paige Horton, bioengineering majors Kamal Shah and Thor Walker and mechanical engineering major Taylor Vaughn. Rebecca Hernandez, a senior in bioengineering, serves as the team’s apprentice leader representing the Rice Center for Engineering Leadership.

    Walker emphasized the old-fashioned engineering of the device: “There’s nothing revolutionary about this thing. It was matter of determining the right weight for the steel counterweight, which is 812 grams, and calibrating everything else correctly.”

    The device can be mounted on a wall or attached with clamps to a portable hospital IV pole. The most time-consuming part of assembling the device was calibrating the counterweight and determining the precise spacing of the notches the counterweight falls into and holds as the fluid drains, he said.

    “Then the clamp goes off and it folds the tubing in a V-shape, the way you would crimp a garden hose to make the water stop coming out,” Walker said.

    This summer Shah and Yuan will transport four of their prototypes to Malawi and Lesotho, respectively, to test them under practical field conditions. Malawi, in southeastern Africa, is among the least-developed countries in the world, with a high infant mortality rate and a life expectancy of about 50 years. Some 1.5 million children in developing countries die annually of dehydration.

    The device was conceived in the fall of 2011 as a freshman project in the Engineering 120, Introduction to Engineering Design course taught by Ann Saterbak, a professor in the practice of bioengineering education and director of laboratory instruction in Rice’s George R. Brown School of Engineering. Team IV DRIP has already received the 2012 Willy Revolution Award for Innovation in Engineering Design, and its members will share a $2,000 prize.

    In April, during the second annual National Undergraduate Global Health Technologies Design Competition hosted by Rice 360˚ and Beyond Traditional Borders, the team won the People’s Choice Award for best poster. They also picked up the $500 Best Freshman Design award at the 2012 George R. Brown Engineering Design Showcase.

    An invention with impact

    BY PATRICK KURP
    Special to the Rice News

    What do you get when you combine a slingshot, a fish tank, a stack of 2-by-4s and five engineering students determined to help the United States Air Force?

    For Team CADET at Rice University, the answer is a device to stop high-velocity projectiles without destroying them. With the Air Force’s current methods, artillery shells are destroyed beyond recovery. The Air Force wants to know more about their behavior as they accelerate and decelerate.

    Team CADET

    Students prepare to test elements of their Controllable Acceleration-Deceleration Equipment Tester, developed at the request of the Air Force. From left: John Stretton, Duncan Eddy, Tremayne Kaseman and William Li.

    “The challenge was to simulate high-acceleration impacts in a nondestructive way,” said Duncan Eddy, a junior in mechanical engineering and member of the Controllable Acceleration-Deceleration Equipment Tester design team. “The problem turned out to have a hands-on, mechanical engineering focus.”

    The other team members, Autumn Allen, Tremayne Kaseman, William Li and John Stretton, recently earned their degrees in mechanical engineering from Rice. Their adviser is Andrew Dick, assistant professor of mechanical engineering.

    Currently, the Air Force simulates deceleration by firing cannons into walls. The strategy is expensive and the sensor module and target are typically destroyed in the process. Team CADET’s goal was to sustain deceleration for at least 10 milliseconds, and without destruction. They machined a cylinder of aircraft-gauge aluminum and sealed a digital accelerometer inside. Next, they built a 14-foot wooden frame to hold a track fashioned from angle iron.

    On one end, they attached a slingshot made from surgical tubing; on the other, above the track, they fitted a 20-gallon fish tank with transparent plastic. Into the bottom of the tank they drilled a line of 40 holes and sealed them with a removable rubber sheet.

    Tremayne Kaseman

    Tremayne Kaseman stretches the slingshot to the max during a test of Team CADET's device.

    When the cylinder holding the accelerometer is fired with the slingshot, reaching a maximum velocity of about 50 miles per hour, the sheet is pulled off and the water is released from the tank. The falling water slows the cylinder, and the rate of deceleration is measured and recorded on the digital device. The cylinder and its contents remain undamaged and the test can be repeated indefinitely.

    “Nothing is destroyed. You just fill the tank with water again and reload the slingshot,” said Eddy, who stressed that the prototype can be scaled to any size.

    We started last fall with a ton of different ideas but ended up with a plan that is simple and inexpensive, and the scale can easily be changed – a bigger tank, more water, more holes, a longer track, a bigger slingshot,” Eddy said.

    In April, the team visited Eglin Air Force Base in Florida and met with members of the Munitions Directorate of the Air Force Research Laboratory, which commissioned the project. The team presented a video demonstration and PowerPoint explanation, and submitted their 65-page final report.

    “They liked what they saw and said they were interested in exploring the idea further. We know we’ve created something entirely new. The parts are not new but the combination is. Also undefined and this is important undefined we came in under budget,” Eddy said.

    Rice University freshmen engineer devices for Houston Zoo to feed giraffes, orangutans

    By PATRICK KURP
    Special to the Rice News

    Like their human cousins, orangutans enjoy food and don’t mind working a little to get it. If the menu’s right, giraffes are even less picky.

    Two teams of students at Rice University’s George R. Brown School of Engineering have designed devices to efficiently, durably, safely and inexpensively meet the feeding needs of these very different residents of theHouston Zoo.

    “For the orangutans, we wanted to make it like a puzzle,” said Julia Bleck, a junior majoring in mechanical engineering who got involved with the project through the Rice Center for Engineering Leadership. “They have mental skills similar to those of humans and learn things pretty quickly, and know how to be patient. We wanted to keep it interesting for them.”

    The Buffoonery

    A team of Rice University freshmen calling themselves The Buffoonery created a maze-like feeder for orangutans at the Houston Zoo. Clockwise, from left: Reinaldo Amendola-Mayorga, Julia Bleck, Jake LaViola, Jade Juzswik and Greta Shwachman. Photo by Jeff Fitlow

    Bleck is the apprentice leader of The Buffoonery, a team name taken from the collective noun used to describe a group of orangutans.Other team members are freshmen Reinaldo Amendola-Mayorga, Jade Juzswik, Jake LaViola and Greta Shwachman.

    “The primate people at the zoo wanted something that would give the orangutans not just food but daily mental enrichment,” Bleck said.

    Last fall the team started with more than 60 possible designs but quickly settled on the idea of a maze. By solving the maze, the Houston Zoo’s six orangutans would be rewarded with nuts or the food pellets they enjoy as a supplement to their customary fruits and vegetables. The team’s prototype is a flat box of high-impact plastic, transparent on one side. Inside is an elaborate maze of wooden slats holding a ball bearing.

    With a magnet, an orangutan moves the steel ball through the maze. If the animal navigates the maze successfully, the ball trips a lever and releases a measured portion of pellets.

    Team Koolookamba

    A team of Rice University freshmen invented a new hanging feeder for giraffes in collaboration with the Houston Zoo. The members of Team Koolookamba, from left, are Adam McMullen, Andrew Markham, Sarah Frazier, Joseph Mapula and Calvin Tsay. Photo by Jeff Fitlow

    The other zoo project is the creation of Team Koolookamba. All of its members are freshmen: Sarah Frazier, Adam McMullen, Andrew Markham, Joseph Mapula and Calvin Tsay. Allison Garza, a junior mechanical engineering student, was the team’s apprentice leader.

    Their challenge was to design a feeder for giraffes that is safe and prevents the animals from consuming the hay it contains too quickly.

    “They already feed the giraffes things like yams and fruit, and up till now they’ve been putting the hay in cargo-net feeders,” Frazier said. “The animals get their horns stuck in the net, and they eat the hay too fast.”

    Using plastic pipe, the team made a barrel-like cylinder about 4 feet long and cut 3-inch circular holes into it. Filled, the barrel device holds about 7,500 cubic inches of hay. Giraffes use their tongues to grasp their food, and the small holes prevent them from quickly emptying the contents. The feeders are suspended 10 to 13 feet above the ground by winches attached to a wooden pole.

    “The students worked hard on a design that met the goals of challenging the giraffes to work to get their food from the feeder and making it convenient for the keepers to get the food into it,” said John Register, the zoo’s hoofed stock supervisor. “They did several prototypes and tested them on our giraffe herd. We’re happy with the final design and plan to use it.”

    Skin no barrier for cardiac charger

    Heart-failure patients may someday get a life-saving charge from technology developed by students at Rice University.

    A team of seniors designed and built a transcutaneous energy-transfer (TET) unit to power a minimally invasive ventricular assist device (VAD) being created by a Houston company. The VAD is a tiny pump inserted into the aorta via a catheter that helps increase blood flow and heal patients with heart failure.

    Rice tCoil – Michael Torre, Erin Watson, Tyler Young, Trevor Mitcham, Hana Wang and Alex Dobranich – made a complementary device that sits a centimeter under the skin and feeds power to the VAD. The challenge presented to the seniors, who were required to complete a capstone design project by Rice’s George R. Brown School of Engineering , was to charge the unit wirelessly.

    “A lot of people need heart transplants, but there aren’t enough hearts available,” Young said. “One alternative is to have a heart pump implanted, but that carries risks. It’s very invasive surgery, and afterward you have to have wire leads running out of your body” to a battery pack.

    tCoil team

    As their senior design project, Rice University engineering students created a transcutaneous energy transfer system to power a ventricular assist device. From left: back, Erin Watson, Tyler Young and Hana Wang, and front, Alex Dobranich, Michael Torre and Trevor Mitcham. Photo by Jeff Fitlow

    The portal through the skin to a power supply can become infected, he said. But the problem is avoidable by sending power to the VAD without wires. The students’ prototype consists of a small coil and a battery that would be inserted one centimeter under the skin at the patient’s waist and wired to the VAD. The patient would also wear a belt-mounted external battery and coil to generate alternating magnetic fields and induce alternating current in the subcutaneous coil. The coils charge the battery, which can operate the pump for more than three hours.

    “The patient can take the belt off for a short time, to take a shower, for instance,” Young said. “The pump will work safely off the coils or on the internal battery alone, but obviously it’s best when they’re both working.”

    The team demonstrated tCoil at the Engineering Design Showcase  that was part of Rice’s recent UnConvention open house. The students put the internal and external coils on either side of a baggie containing lunchmeat to simulate power transfer through the skin. The internal unit was wired to a demonstration pump that clearly pushed red-colored water through a sleeve inside a tank.

    tCoil prototype

    A prototype of the transcutaneous energy transfer device created by Rice University students is meant to charge a battery under the skin that powers a tiny ventricular assist pump used by heart patients awaiting a transplant.

    The student project was in response to a request from Rice alum Michael Cuchiara, director of research and development at Procyrion , developer of the pump.

    “I mentored two senior design teams while I did my Ph.D. in bioengineering at Rice and helped bring a project to Maria Oden (a professor in the practice of engineering and director of theOshman Engineering Design Kitchen  at Rice) for a different client company in 2009,” Cuchiara said. “For this project, until recently, our company’s expertise was not heavy in electrical engineering design, and I knew Maria could put together a good team.”

    He said the students, who were mentored by Oden and Gary Woods, a Rice professor in the practice of computer technology and electrical and computer engineering, came through for him. “The Rice team brought us a quick, capital- and resource-efficient proof-of-concept system to show we can power our device through TET,” Cuchiara said. “There’s was no reason to think we couldn’t – but until you do it, you don’t have it.”

    The project is far from complete, Young said. “Erin will work on it this summer, but at some point Procyrion will take it over and continue development,” he said. “The next steps will be to miniaturize it and put it in biocompatible casing. Once that’s done, it can be implanted for large animal testing.”  Ideally, he said, the long process of approval by the Food and Drug Administration will follow.

    But team members will graduate with the satisfaction of a job well done and two awards: for Best Interdisciplinary Design Project at the Design Showcase and for best medical and rehabilitation technology at the third annualRice Undergraduate Elevator Pitch Competition  last November.

    Cuchiara said TET will make ventricular assist available to an ever broader set of patients. “The concept that you can induce a current in another coil without connecting them electrically has been around since Tesla ,” he said. “And VADs have been around for more than 10 years. But before, they were offered to people who were on their deathbeds. Now that we’re able to take the risk (of passing a wire through the skin) out of the equation, we’re starting to talk about bringing VADs to people who aren’t that sick and can just use a little bit of support.”

    The "FluProof" ultraviolet lamp kills pathogens as they pass through a bus's air duct. Rice engineering student Joey Spinella says the team wanted the lamp to be visible to passengers. "So they can see that and they can have the peace of mind in knowing that this bus is clean," he said. "But another practical reason we have that is it's an indicator, you can see if the lamp is working correctly."

    May 7, 2012

    by: Carrie Feibel

    Some Rice University engineering students have developed a technique to sterilize the air on a bus. The invention has a lot of public health potential, and Metro is watching closely.

    “So here in the back of the bus we see this bright blue glow coming out of a plastic window on the top of the bus.”

    Joey Spinella, who will graduate this week, is showing me his team’s invention. It’s called “FluProof” and consists of a glowing ultraviolet lamp that bus riders can watch through a plastic window.

    The lamp is smack in the middle of the bus’s air duct, so as the air passes through the UV light instantly zaps dead any bacteria or viruses.

    “This could actually be something that could revolutionize air sterilization for any transit vehicle, especially in the developing world where many other people have upper respiratory diseases like tuberculosis.”

    Tuberculosis is also a problem here – the CDC reports Houston had the second most reported cases in the U.S., after New York City. Although it’s never been proven that public buses transmit TB, a number of studies indicate that it does sometimes happen.

    Marsha Feske is an epidemiologist who studied TB and Houston bus routes while doing research at Methodist.

    “Tuberculosis, once it’s respirated, it’s negligible to gravitational forces and so it remains airborne for up to nice hours. And the problem with that is someone can get on a bus and cough and actually respirate it get it into the air to be airborne, and then it continues to float around and potentially infect whomever else is on the bus for the rest of the day. So you don’t actually have to be riding public transportation with the person who has TB, you just have to ride the bus that someone who was coughing and had TB rode.”

    Buses present a special challenge when it comes to filtration. A bus’s electrical system runs on DC voltage, which means there isn’t enough power for the HEPA air filters used in buildings and on airplanes. That’s one reason METRO is interested in the FluProof lamp.

    Andrew Skabowski is a senior Vice President at Metro and arranged for the students to install and test the lamps on a METRO bus:

    “I think there’s a lot more to do, it’s not market ready yet, but I think they’ve done a  wonderful job. They were able to deliver a system below what my cost expectations were and they were able to do some testing to show that indeed it does reduce some bacteria within the bus.”

    Spinella and four other students tested the system and found it killed more than 99 percent of the bacteria circulating through a normal bus.

    They claim it can be manufactured for less than $500 per unit.

    They’re in the process of drafting a business plan.

    Two staffers make their departments shine

    To celebrate the Rice Centennial, this year the university will honor 100 staff members who represent the best of Rice culture. Each week, two Centennial Stars will be recognized for their contributions to excellence, and we’ll introduce them in Rice News.

    This week’s Centennial Stars have transformed the programs they work for and used considerable skills to make their departments shine. They are Amy Kavalewitz, Rice Center for Engineering Leadership (RCEL) administrator, and Mary Bixby, who serves a dual role as director of development for Fondren Library and executive director of Friends of Fondren Library.

    Amy Kavalewitz

    Amy Kavalewitz

    Kavalewitz was hired in 2006 as coordinator of the Computer Information Technology Institute, which is now the Ken Kennedy Institute for Information Technology. In 2009, she became administrator of the Oshman Engineering Design Kitchen (OEDK); when the RCEL launched in 2010, she became administrator of that program as well.

    Kavalewitz “matches high creativity with indefatigable industry to make a profound contribution” to the OEDK and RCEL, said the letter that nominated her.

    “Amy has substantially shaped the culture of this highly productive space,” the letter said. She has played an invaluable role in supporting student capstone design projects, in building relationships with industrial partners and in encouraging undergraduate entrepreneurship, the letter said.

    Kavalewitz has helped in crafting OEDK access policies, encouraged safety with signs and video and contributed substantially to “the creative buzz that characterizes the OEDK.” She assembled an “array of luminous judges” for the student poster competition at the RCEL’s recent Engineering Houston’s Future conference. And finally, she has “a deep facility for website development, social media and the identification of new tools to expedite our organizational operations.”

    “Amy has been instrumental in organizing numerous RCEL activities with her characteristic skill,” the nomination letter said. These events often involve working with other organizations – the Rice Alliance, the Baker Institute for Public Policy, Leadership Rice, the city of Houston – and Kavalewitz “has exhibited an excellent ability to collaborate across organizational lines.”

    Kavalewitz has been honored for excellence before. In 2008 she received the Rice Distinguished Employee Award, and she was the winner of the 2010 George R. Brown School of Engineering Hardy Bourland Award, which honors the school’s most outstanding staffers.

    “Amy is a linchpin of the Oshman Engineering Design Kitchen and the Rice Center for Engineering Leadership,” the letter said. “Her personality and high standards have shaped both organizations, and her creativity is invaluable.”

    Bixby came to Rice in 1996 as the executive director of Friends of Fondren Library. In 2000, she

    transferred to Development to become director of development for the library. In 2002, Bixby went back to her former position with Friends of Fondren, and she now does both jobs, working part-time in each position.

    “Mary has led the Friends of Fondren Library from a small club with occasional social events to a major nonprofit,” said the letter that nominated Bixby. “Friends of Fondren is arguably the best library friends group in the United States.”

    In her tenure, the letter said, Bixby has led efforts to raise nearly $1.5 million for the library.

    Bixby has used her skills to help the university in other ways as well.

    “In addition to organizing major social and fundraising events for the Friends, Mary brought her social organization skills to leading the inauguration planning for President David Leebron” in 2004, the letter said.

    Bixby’s work supports the university’s research and teaching, the letter said, and her graceful manner makes her an excellent representative of Rice.

    “Mary is gracious and charming and displays courtesy, tact and consideration in her interactions with everyone,” the letter said.
