2Client Background
- Mount Pleasant Blythedale School in Westchester
County is linked with Blythedales Children
Hospital. - Together the two provide therapy and treatment to
children ranging from 4 to 12 years old who need
daily medical treatment and cannot otherwise
receive such care in a traditional public school
setting. - The unique hospital and school combination allows
students to receive medical treatment, attend
school, and have leisure activities during the
same day.
3Problem Space
- Although the system weighs less than 5 pounds
when the feed bag is full, younger students
cannot support the weight on one shoulder. As a
result they must request that the accompanying
adult carry the bag. - The current shoulder bag is not aesthetically
pleasing to the students. - Therefore, Blythedale School and Hospital
requires a bag with two straps, similar to a
backpack, that will evenly distribute the weight
of the bags contents to make the bag feel
lighter, in addition to the bag looking like an
everyday school backpack.
4Current Backpack
The current one-strap design holds the pump at
the bottom and the liquid feed pack inside of the
sleeve at the top, which unevenly distributes the
weight when the bag is worn.

as pictured in Figures 9 and 10. - To attach the pump to the backpack, a foam spacer

14Alternative Solutions
- Alternative Solution A
- Modify a commercially available backpack to
resemble the teams final design. - The inside compartment could be altered to allow
for the pump and feeding bag to be placed inside. - A small hole could be cut on the side of the bag
and then reinforced with stitching to allow the
tubing to exit the backpack. - Velcro strips could be sewn to the bottom of the
backpack and attached to the bottom of the pump
to keep it in place.
15Alternative Solutions (continued)
- Alternative Solution B
- Kendall, the company that manufactures the
Kangaroo ePump, also manufactures a two-strapped
bag designed for the pump, priced at 270-400.
