ASAP: Automated Sigma Analysis Platform
Our team has been working with Baxter to improve optical and software techniques to quantify flow rate of their Sigma Spectrum drug infusion pump. Current methods for flow rate calibration of hospital infusion pumps are subjective and prone to errors such as evaporation. Developing an accurate and thorough calibration set-up can be tedious, costly, and space-inefficient. We have developed a novel, inexpensive calibration device to validate infusion pump flow rate intended for use in research and development, and quality assurance of Baxter’s pumps.

Cable Medical ECG Cable Adapter
In a hospital environment, time is a commodity. Currently, hospital workflow is impeded by clinicians’ need to change ECG systems as a patient moves through the hospital throughout their stay. We aim to modify Curbell Medical's existing ECG cable system in order to limit disruptions to clinical workflow and minimize the hospital’s waste caused by discarding incompatible lead sets. The solution consists of a permanently attached, optimized cable-adapter module which enables smooth navigation through hospital-identified critical pathways.

Sepsis Detectis Team 


Our team is working to combat the drastic hospital mortality rates of sepsis by developing a faster detection technology. We aim to implement hyperspectral imaging as a non-invasive diagnostic tool for use within an intensive care unit. Instead of conducting cell cultures and blood tests, which are both invasive and time consuming, the goal of this device is to help detect and quantify the presence sepsis in minutes.
Team members: Kathleen Larson, Dylan Latham, Justin Schumacher, Brittany Schutrum, Joshua Schum
Supervisor: Dr. Catherine Kuo
Customer: W. Spencer Klubbens

CTEV Brace Team

Our team has been tasked with creating a better brace to treat CTEV (clubfoot), a congenital deformity where a child is born with their feet turned inward and upward. The current method, the Ponseti Brace, is a boots and bar system with many drawbacks. Aside from restricting movement, it’s uncomfortable and difficult for parents to use. As a team we have created a barless alternative brace that is lighter and more comfortable, while also tracking patient compliance. We hope that our brace can be used to improve the lives of children with CTEV and their parents everywhere.

Dialysis Patient Simulator Team

Fresenius Medical Care is a leading provider of hemodialysis products and services, treating more than 300,000 patients worldwide. Currently, there is no product that can perform patient simulations for new dialysis machine prototypes. Our device interfaces with a hemodialysis machine just as a patient would in order to simulate changes in fistula blood pressures, hematocrit, and oxygen saturation. It also monitors these pressures, bloodline flow rate, and dialysate temperature to ensure that the sensors and responses within the prototype are correct.

OPTI (Optimal Photoacoustic Transmission Imaging) Phantom Team
Photoacoustic Imaging (PAI) is an imaging modality that combines both optical near-infrared and ultrasonic imaging. For PAI to be implemented in the clinical environment, there must be a reproducible method for calibrating and verifying the imaging system parameters. Our team is developing a phantom that will model the imaging of blood vessels in human tissues. These phantoms will be used to determine the spatial resolution of Dr. Navalgund Rao’s PAI system for imaging vessels of varying depths and diameters

Pediatric Assisted Locomotion System (PALS)


We are working with local pediatric physical therapists Kelly Gilroy and Leah Talbot to design a PT system to teach children with motor delays resulting from Down syndrome and cerebral palsy to walk. Children with motor delays learn to walk a year late on average, and because of this, tend not to hit developmental milestones on time. Our treadmill-based supportive gait trainer aims to teach these children to walk earlier, giving them more independence and the capability to explore and learn about their surroundings.
Team members: Alex Kazmierczak, Courtney Semkewyc, Jolan Burger, and Nitish Sardana

Customer: Leah Talbot, MSPT, Roosevelt Childrens Center and Kelly Gilroy, PT, DPT

Pediclear
During spinal fusion procedures, surgeons need a better way to detect defects in the pedicle tract in order to determine whether it is safe to implant pedicle screws. We designed a surgical probe, Pediclear, that senses changes in vibration pattern as it moves against the walls of the pedicle tract and alerts the surgeon to the presence of a breach. The solution adds certainty to breach detection, reduces false positive rates, and aids in resident training without adding extra time, equipment, and cost to the procedure.

Proteus Medical

Canines are the most common offenders of consuming foreign bodies, requiring a veterinary visit to remove the object to prevent further harm. Endoscopic retrieval is the preferred method of extracting these foreign bodies. However, endoscopic retrieval devices on the market today are neither robust nor reusable, often deforming after single use. At Proteus Medical, our team has developed a unique design that will reduce both the retrieval time and yearly expenditures. Together, we aim to revolutionize the endoscopic retrieval field through our novel device.

Fetal Cardiac MRI

Alex Choy, Andrew Graveley, Kevin Jin, Tae Jun Yoon

MRI is the best option for diagnosing potential issues in fetal hearts, as the technology provides high resolution and lacks harmful ionizing radiation. However, MRI is limited due to the inability to measure the fetal heartbeat for selectively timing the image acquisition. By designing a device that can safely obtain an accurate fetal heart rate and communicate this information to the MRI machine without interfering with the imaging process, we aim to improve diagnosis of congenital heart defects before birth.

Vestibular Vibes

Yuqi Wu, Luke Daily, Ian Baranowski, Allison Stiller, Tristan DeAlwis

Benign Paroxysmal Positional Vertigo, BPPV, is a condition caused by detachment of otoconia (calcium carbonate crystals) from the otolith organs and subsequent migration of otoconia into the semicircular canals. Presence of these otoconia creates a false sense of acceleration in the patient by stimulating the vestibular hair cells, thus causing nausea and vertigo. Therefore, we intend to design a vibrational device that can be applied to the mastoid of the patient in order to deliver oscillations capable of breaking apart the clumped otoconia.

Erica Marron, Angela Ryck, Danielle Wilson

Our mission is to help orthotists create the optimal brace for each patient’s unique spinal curvature. ScoliFit is a wearable torso-positioning device designed for use on adolescent idiopathic scoliosis patients. This device can determine the torso position that immediately reduces a given patient’s spinal curvature and enables orthotists to incorporate that position into the profile of the patient’s final brace. Since the current method of making braces is subjective and has no such capacity for validation, ScoliFit is unique in its ability to establish the optimal brace design before the brace is made.
