New discoveries and advancements in the medical field have introduced a myriad of life-saving therapy options for patients across the globe. But what does it matter if tremendous costs and inefficient processes cause those therapies to be inaccessible?

A group of seniors in the Paul M. Rady Department of Mechanical Engineering are working to solve that problem by developing an automated medical fluid aliquoting device during their senior capstone design class.

The project, sponsored by Terumo Blood and Cell Technologies, is a user-focused system that employs a rotational fluid distribution mechanism to divide and organize medical fluids into disposable bags. These fluid-filled bags can then be taken to hospitals for administration or stored for later use.

“A lot of different medical facilities need systems that can aliquot or essentially ‘dose out’ medical fluid for various applications,” said CAD engineer Zachary Goldberg. “Our device improves upon those previous systems by increasing the capacity of fluid samples that can be created and reducing the amount of space that the system takes in medical labs.”

Through human factors input, the group has found a way to streamline and automate the process to minimize labor-intensive interactions.

“In medical aliquoting, anything that a fluid comes in contact with needs to be disposed of after every single run to maintain a sterile product. So the operator is regularly unloading and reloading the tubing from the system,” said logistics manager Lia Cucuzzella. “This is a process that takes precious operator time with the existing machinery. Our device aims to streamline the loading process.

“This could reduce the cost of labor and help increase patient access to the therapies associated with these fluids.”

The medical aliquoting device is the first of its kind in the Senior Design program. Instead of having a foundation of designs created by teams in past years, the group started brainstorming with no reference points and no restrictions.

In many ways, this open brainstorming period enabled the group to push the boundaries of their project. But it also proved to be an obstacle.

“I’ve often felt that constraints on projects create smooth thinking,” Cucuzzella said. “When you are given a clearly defined project, it’s easier to think creatively within that space. For us, the bounds were so large that it was difficult for us to come up with an identity and define our own specifications.”

Still, the group was able to come together and find an innovative solution that combines precision and practicality. The team says they’ve learned a lot along the way, including the importance of working together as a team.

“When you have a good team with incredible people who are passionate about what you are working on, the potential is endless,” said project manager Ana Quiñonez. “Our team dynamic and our willingness to work with each other is a culture I will look to maintain going forward.”

The group says their year-long journey has told a story that they are excited to share with attendees at this year’s Engineering Expo event. Not only will people be able to see the progression of their project, but they will also get to see the development of their friendship in a fashion reminiscent of an old scrapbook of pictures.

They are also hoping to have another surprise: a demonstration that invites all visitors to try their device.

“A part of our mechanism is being user-focused and easy to manage,” said Quinonez. “What better way to explain our story than to let the audience load and operate our device?”

ME senior project aims to keep bomb squads out of harm's way

Bomb squads across the nation put their lives on the line everyday to protect others. But who is working to protect them when they are out in the field?

A group of seniors in the Paul M. Rady Department of Mechanical Engineering are working to fill that gap by developing an automated X-ray device during their senior capstone class used to help explosive ordnance disposal (EOD) technicians scan for hazardous materials.

The project, sponsored by Los Alamos National Laboratory, is the first of its kind in the Senior Design program. It’s designed to address key efficiency and safety issues that bomb squads encounter when dealing with explosive devices.

“Currently, EOD technicians are holding a tripod with an X-ray panel connected to it and manually scanning for explosives and other objects. It’s dangerous and it’s not nearly large enough for the objects they want to scan,” said project manager Thomas Montgomery. “We want to make sure the technicians are safe and they can do their job with more consistency and precision.”

The team's automated X-ray bomb disposal device, sponsored by Los Alamos National Laboratory.

To do this, the team attached an X-ray panel to a two-armed system powered by a series of motors with a torque output equivalent to a Prius. This allows the arms to swing and swivel to capture images anywhere within a 68-by-56 inch view without anybody getting too close.

The group says their automatic device also allows for faster setup and image processing capabilities—both of which are very important when bomb squads are working against the clock.

“Sometimes when the operators are scanning for objects, they come across overlaps in the images that are inherent in a manual process,” Montgomery said. “Our device keeps the operator further away from the danger, and it’s repeatable. It can precisely combine all of these images with consistency and that’s incredibly crucial during these high-stakes situations.”

It’s a novel approach to a tangible issue. But despite their success, the group said it wasn’t always easy.

The biggest challenge came all the way at the beginning of their capstone journey. When the team began brainstorming different designs and solutions, it became clear that there were quite a few dissenting opinions on how they should tackle this project.

“I was definitely one of the biggest voices of dissent on some of our original ideas,” said logistics manager Luca Voeller. “I think it was actually a good thing for our team. It really forced us to identify the flaws in our designs and come back to the group with solutions.”

Once they settled on a design, the group encountered their next big challenge: budget.

They found out right away they were going to need a motor capable of producing enough power to keep each of the 15-pound arms steady and moving. But purchasing one would blow a devastating hole in the rest of their project.

“Two weeks in we realized we needed a $3,000 motor and we most likely weren’t going to be able to do the project,” Montgomery said. “We spoke to support staff and they were miraculously able to get us one.

“It really shows you the importance of the resources here at the Idea Forge. Sometimes [the staff] brings you into some random closet somewhere and just pulls something out that saves your entire project.”

Navigating obstacles and issues is a staple in the senior capstone class. Whether it’s managing team dynamics or budget constraints, the program is designed to prepare graduating undergraduate students for industry experiences.

For this group, it was a rollercoaster ride. But they believe their struggles taught them a valuable lesson for the future.

“Don’t be afraid to fail. Fail early, fail often,” said Voeller. “The best way we learned all year was by messing up and making mistakes.”

This year’s Engineering Expo is on Friday, April 25 at the CU Boulder Indoor Practice Facility from 2-5 p.m. Make sure to drop by and check out all the exciting projects in action!
