Oxygen Tubing Management

Project Partner: Travis Clifton

Team Members: Cameron Crawford, Hannah Jung, Nara Jung, Luke Pritchett 

Date: 12/04/2024 Version 3

Mission Statement: Design a compact, neat, hands-free, structure that can manage and organize oxygen tubing to prevent tangling and kinking while the user moves around the house. 

Project Deliverables:

• Final report

• Presentation

• Poster

• Final prototype

Design Constraints:

• Time (we have less than 10 weeks to complete the final prototype)

• Budget is $150

• Limited mechanics skillset 

Users and Stakeholders:

• Mark Clifton, user, will use the device to prevent the tangling of his oxygen tubing

• Travis Clifton, project partner and stakeholder, assists Mark by periodically detangling the oxygen tubing to keep it organized and less of a tripping hazard

• Mark and Travis’ Daughter, stakeholder, lives in the house when she is not at college

• Mark and Travis’ Cats, stakeholders, interact with the tubing on a daily basis, stepping on it

User Profile

Mark Clifton is a 69-year-old man (pending consent) with interstitial lung disease (ILD). To treat his ILD, he practices oxygen therapy via a stationary oxygen concentrator (at home) and a portable concentrator (in public). His ILD causes difficulty breathing and creates challenges for physical activities.

User Scenarios

Mark Clifton wakes up in his bedroom. His wife, Travis, must help him unravel his oxygen tubing from the wall so he can move about freely. As he walks through the hallways of his household, he struggles with mobility as the tubing has a tendency to tangle and kink from excessive movement. His wife and their cats also have trouble maneuvering the household as the tubing trails behind Mark through the halls. When leaving the household, he must transfer his oxygen source from a stationary one to a portable one. He carries his portable oxygen concentrator, which weighs about 20 lbs, in a backpack. While cooking, Travis must take care of everything involving the oven, as he cannot risk being around high temperatures with his oxygen tubing. At the end of the day, he and Travis must rewind his tubing before going to bed.
