|
|
To design, build, test, and evaluate a device to
aid in identifying the radial artery in children. |
|
To explore optical properties and wavelengths of certain materials. |
|
The device should be user-friendly. |
|
The device should cost no more than $300. |
|
|
|
|
Premature infants undergo various surgeries. |
|
|
|
|
|
|
Anesthesiologists need to insert catheters into
the radial artery. |
|
|
|
|
|
|
|
This is very time consuming and adds to costs
and morbidity. |
|
There is no device as of today to easily examine
the little arteries. |
|
|
|
|
|
|
An artery in the forearm, wrist, and
hand. |
|
The one usually used for taking the pulse. |
|

|
|
Size: Weight, Adjustable Wrist Position |
|
Light Source: Adjustable Intensity, Heat,
Rechargeable, Wavelength |
|
Design Consideration: Cost, Age, Ease of Use,
Materials, Position Marker |
|
|
|
|
|
Size: Use a light weight plastic that is both
environmentally friendly and bacterial resistant |
|
Light Source: Use LED bulbs along with a
variable resistance switch. |
|
Design Consideration: |
|
Use store-bought materials for easy repairs |
|
Universal design to fit all ages |
|
Use inexpensive building materials to meet or
excel on cost considerations. |
