Lenard Christian Tolentino & Matteo Bazzuro



Awarded ‘Best Prototype’ at the workshop hosted at NASA Johnson Space Center in Texas


Background



NoviRad Inc. is a Houston based, seed-stage medical device startup developing percutaneous drainage solutions to remove abnormal fluid collections from the body. NoviRad is designing a bedside solution for in-patient care, but would like to explore outpatient solutions to improve mobility and quality of life for the patient.



Research

Percutaneous drainage systems involve placing a catheter through the skin to collect infected fluids such as abscesses from the body. When these fluids aren’t properly drained, patients might face sepsis. To prevent this, periodic flushing of drainage bags with sterile saline is required.




Problem


Current drainage solutions limit the patients’ mobility, making them reliant on nurses and caretakers to swap their bags for them and some patients need to wear these drainage systems for 14 to 28 days.


Objective


Design a wearable inpatient solution for NoviRad’s smart drainage to improve the mobility and quality of life of patients recovering from abdomen-related infection with reservoirs that can be easily swapped by the patient.

Initial Concepts & Mockups







Final Design Drawing


To arrive to our final design drawing, we kept positioning of the Side Saddle Bag and implemented the silhouette of the Fanny Pack concept.


Schematic of Electronics

This map illustrates how we imagine the electronics to be wired based on the specs we were provided by our mentors.



Exploded View

We engineered the electronics box to ensure constant accessibility to the pumps. However in the event of system malfunction, the users can still reach the battery, motor driver, Bluetooth adapter, and Arduino by unscrewing the front piece.
