The robot can autonomously place an IV in an astronaut\u2019s arm for crewed space missions and to improve access to healthcare on Earth.<\/h4>\n
Designing a robot to autonomously place an IV in an astronaut\u2019s arm while in zero gravity requires smart, passionate, persistent engineers. What better team for the project than Duke physician-engineer\u00a0Dan Buckland<\/a>, who is both assistant professor of mechanical engineering and materials science and an emergency department physician, and mechanical engineering doctoral student\u00a0 Siobhan Oca<\/a>?[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_single_image image=”1268″ img_size=”full” add_caption=”yes”][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_column_text]<\/p>\n
\u201cNASA needs to both expand the medical capabilities available on a Moon or Mars mission and reduce the number of trained medical personnel required to achieve mission objectives.\u201d<\/p><\/blockquote>\n
[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_column_text]NASA is on board with the idea, recently funding their project, \u201cAutomated Vascular Access for Spaceflight,\u201d through its\u00a0 Human Research Program<\/a> with a one-year, $150,000 grant.[\/vc_column_text][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1535394535521{padding-top: 15px !important;}”][vc_column][vc_column_text]<\/p>\n

Buckland said autonomous medical procedures can further those goals, and that placing an IV autonomously would be particularly helpful as that\u2019s the first step of almost any medical procedure or diagnosis.<\/p>\n
This first step of the long journey toward sending the robot aboard crewed\u00a0 Artemis<\/a> missions to the Moon, and later Mars, will take place on the ground, however. By the end of this grant, Buckland and Oca hope to have Institutional Review Board approval to test the robot on human arms. Hopefully, that will lead to funding to test the prototype during spaceflight.<\/p>\n

Easy as child\u2019s play? While not an official test of its ease of use, Siobhan Oca allows one of Dan Buckland\u2019s children to maneuver the robot\u2019s arm from a touchscreen in the lab. Buckland and Oca are designing this complex medical robot for NASA specifically for astronauts without advanced medical training to use in-flight on missions to the Moon or Mars.<\/figcaption><\/figure>\n
Robots that insert IVs into patients\u2019 arms already exist, said Oca, but they all require clinician oversight. The one Buckland and Oca are designing is for use by someone without clinical training or even a clinician nearby. It uses a noninvasive ultrasound probe to locate the correct vein\u2014importantly distinguishing it from an artery. Unlike other robots, though, for human safety, it must also have parts that remove easily for sterilization in an onboard autoclave or are disposable. The motor, which cannot be superheated in an autoclave, also needs protection from contamination along with calibration to operate in zero gravity.<\/p>\n
\u201cThe system must be easy to clean and easy enough to use that you don\u2019t poke yourself with the needle. Add to that, it must be lightweight, reliable, and inexpensive,\u201d said Oca. \u201cWe\u2019re actually using a fairly low-end, inexpensive ultrasound\u2014that\u2019s the point.\u201d<\/p>\n
This project fits into an all-encompassing dream they both have, which is to make medicine more accessible, especially in low-resource settings. Space, with its many constraints and limited onboard supplies, is a low-resource setting. Others here on Earth include\u00a0the U.S. Indian Health Service with its remote locations and shortage of clinicians.<\/p>\n
Oca is no stranger to persistent pursuit of her passion amid constraints, including those that occur without warning. When she was 11, her family fled the devastation of Hurricane Katrina from their native New Orleans and resettled in Richmond, Va. During her freshman year at a public high school for academically gifted students, while on a path to become a doctor in the footsteps of both her parents, she inexplicably lost a significant portion of her vision.<\/p>\n
With a still unwavering passion to help people through medicine, she pivoted to undergraduate study of mechanical engineering at MIT and then earned a master\u2019s degree in translational medicine from a joint program at the University of California\u2013Berkeley and the University of California\u2013San Francisco. From there she joined a startup company using her newly acquired know-how in regulation and marketing to help them commercialize a medical device.<\/p>\n
\u201cI realized though that I want to be the person who helps to decide the design, and so I decided to go back for my Ph.D.,\u201d she said. That decision brought her to Duke\u2019s Ph.D. program in mechanical engineering and materials science in 2018.<\/p>\n

\u201cIt was such luck that I get to work\u00a0with Dan because he wasn\u2019t on the faculty when I applied to Duke. I kind of fell specifically into medical robotics because of Dan, and I am very excited that I did,\u201d she said.<\/p>\n
This is where her persistence comes in\u2014like a well-developed muscle strengthened from daily use. She uses her cell phone to magnify documents for reading and her spatial memory to memorize the layout of icons and commands in software. She also uses many other effective workarounds that have enabled her to mentor undergraduate students in making designs for the ultrasound holder and angling mechanism of the robot using computer-aided design (CAD) software.<\/p>\n
\u201cEvery new software I have to use, I memorize where everything is. I know where everything is in Microsoft Word,\u201d said Oca. She also plays to one of her strengths, which is coding and programming the human-robot interaction, because she can more easily enlarge it on a screen.<\/p>\n
\u201cI\u2019m passionate about building things to help people,\u201d she said.<\/p>\n<\/div>\n
