Client 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.

Problem 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.

Current 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.

  • Weigh less than one pound
  • Be constructed out of 600 Denier nylon or
    polyester
  • Cost less than 80
  • The dimensions should not exceed 14 x 7 x 11
  • The pump should not move more than ¼ inside
    backpack

7
Functional Requirements
  • Washable, durable, comfortable
  • Allow for easy access to contents
  • Include carrying handle
  • Fit children of various sizes
  • Distribute weight evenly

8
Final Design
  • Has two padded foam straps and a padded foam

  • The feeding bag and pump are aligned in the
    center of the bag to distribute weight evenly.
  • Feeding tube can exit the backpack from either
    the left or right.

As pictured in Figure 1, the pack has two
zippers, which allow for access to two
compartments when opened. Figure 2 shows the two
compartments of the backpack where the pump and
feeding bag are positioned. Figure 3 shows the
padded straps which can be adjusted to the users
preference.

Major Design Features (continued)
  • The backpack design includes a polyurethane foam
    padding in the backing and straps, to provide the
    user with maximum comfort.
  • The backpack also has a handle so it can be
    carried.

Major Design Features (continued)
  • There is a small elastic strap to hold the
    feeding bag in place, while inside the mesh bag,
    as pictured in Figures 9 and 10.
  • To attach the pump to the backpack, a foam spacer
    will be attached to the bottom of the pump with
    adhesive, and Velcro will be attached to the
    bottom of the spacer as pictured in Figure 11.

Alternative 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.

Alternative 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.
