Who is moving patients

Identify an Opportunity

It is expected that 55% of nurses will retire between 2011 and 2020

Most lifting tasks involve moving a patient from bed to wheelchair

Patients are frequently repositioned for different reasons, such as meals.

“Once it took me an hour to find an IV pump.”

“There are a lot of tubes and cords that are held and organized by hand.”

Research the Hospital Environment

Through visiting hospitals and volunteering for a semester, real observations, sights, and sounds could be observed.

Observational Findings • Tubing gets tied when transfering the patient

• Tubing can force the patient to be immobile

• IV lines can get kinked and tripped on

• IV poles and bed are moved by one person

• Line slack is held by the nurse’s hand

• Lines can stretch across the patient’s bed

One mother could not hold her baby in fear of pulling the tubes out. (Visual immobilization)

Baby warmer includes slots for lines but are not used because they snag the tubes.

Patient fiddles with tubing that is in the way

Crossed lines become harder to manage

Tangled tubing takes time from the nurse’s routine

Tangling around equipment

Tripping hazard

Multiple lines overwhelm and immobilize the environment and the patient

Taped lines to the bed rails near the head rest

In one case, a baby strangled and died in 45 min from tangled tubing

Research images of Patients and Tubing

Still has loose lines

By stiffening the tube it prevents entanglement

By locking cords in place it is hard to adjust them

Other ideas intend to wrap individual tubes around a mechanism, which can be time consuming

Tubes are still messy near the patient

Research current Organizational Products

Straight forms allow the tubes to flow with out getting clumped up.

A stretchy adhesive could provide a cheap disposable adjustable solution

A cradle could hold the lines together but be loose enough for tube adjustment

Soft forms provide a safer and more comfortable feel when sitting next to the patient.

Ideation with Sketching

Lines must be loose to allow tubes to be adjusted

Lines don’t gather well on a cone bucket

Lines are visually and physically organized

Testing with Sketch Models

A cradle can hold the lines and be loose at the same time

Holding them down causes the tubes to snag

LAY LINEA system of cradles that gently reduce tangles and visual disorganization of tubes around hospital equipment and the patient, while allowing the user to be more comfortable and mobile in their environment.

Resolution the Concept

Patient StickersStickers allow patients some control over their hospital stay. Notes can also be written about the patient for the hospital staff.

Packaging and StorageThe LAY-LINE’s small size reduces the need for frequent stocking and egg hunts for the item.

Resolution the Story

Clip and CradleThe clip and cradle reduce tube entanglement with bed equipment and the patient themselves. The two organizers increases the user’s control of the tubing.

Line Cradle

Bed Rail ClipThe bed rail clip holds IV lines and larger lines such as feeding tubes.

The line cradle holds IV lines which can bend and tangle more.

Resolution the Safety and Adjustments

As the patient becomes healthier, with less tubing, and starts to move, they can slide the cradles together and hook it on the IV pole.

Easy collection of tubesThe two cradles can be slide together to easily the tubes. This helps organize the tubing when moving the patient.

Resolution the Patient Mobility

Low-Friction/Flexible CoatingFluoroBond is a chemically bonded coating that reduces the friction with silicone while keeping the flexible properties of silicone.

Injection Molding Insert MoldingMedium durometer 70A FDA silicone rubber. This provides a hard shell on the outside to protect the tubes.

Low durometer 60A FDA silicone rubber. This provides a soft area for the tubes to lay on.

SterilizationThe LAY-LINE parts are reusable and the medical grade silicone rubber can be sterilized with “Sporicidin Sterilization Solution” since it does not enter the body.

Resolution the Manufacturing

“This is a promising concept, the

main hurdle is getting hospital

administration to buy it” - Nurse

“This would work well for children who tend to have more energy and move around more often” - Pediatrician

“This could work best in ICU where they can have up to 6 lines at once, which are changed everyday” - Nurse

“The concept could work best in ICU where patients can have up to 6 IV lines” - Nurse

DACFrom professional to consumer audio

A professional audio company sought a design enclosure that would attract both consumer and professional audiophiles

for a new digital audio converter.

What is a DAC?

Why have one?

Visual Elements

A Digital Analog Converter (DAC) converts a digital sound file. It is similar to the sound card in your computer but is a separate unit.

Why have separate speakers for your laptop? It enhances your audio experience.

By recognizing key elements in the company’s products one can design for consumer market with out losing the company’s brand. Some elements are the rounded rectangluar apatures that section off different functions.

Research the Target Market

Analog vs Digital

Professionals require audio electronic units to be rack mounted for accessability and storage.

Consumers want their electronics showcased for everyone to see. These units are usually shelved on platforms in the living room, entertainment room, or pure audio room. The visuals become part of the audio experience.

Professional and Consumer Needs

Although the aesthetics are not the most important attitbute, the visual interface should be clear and give percise control.

Although both segments have different environments, they agree that analog is nostalgic and represents authentic sound and something that isn’t hampered by how large the file size is.

Q: How can the concept of analog be implemented?

Partitions help define the DAC’s different abilities for the user

L Brackets could be configurable for different users

Rectangular forms stay within the original form’s language

Ideation with Sketching

Selective dial controls meld both analog and digital control to the machine

Reconfigurable Brackets meld both analog and digital control to the machine

Final Concept the Interacting with the Environment

“We use polished aluminum which takes its color from its surroundings instead of dictating to them.”

-David Lewis of Bang & Olufsen

The low volume of the product and the advancements in CNC machines allows the parts to be machined, finished, and engraved.

Corners get damaged when moving furniture and bags

Holes are created by nails, hooks, screws, thumb tacks, etc.

Moving OutHoles and dents are created from hanging things to the walls, from moving furniture and luggage out of the room on corners. It may not even be the person’s fault but the previous owner’s
