PROJECT LIFE RAFT DESIGNING A LOWER COST INFANT INCUBATOR Project Goal: The goal of this project is to develop a functioning prototype of a low-cost incubator and isolation unit for infant care in developing countries, in collaboration with

The goal of this trip was to further the research done in
- January. Student teams had the opportunity to go
deeper, in context.
We‟re nearing the end of our observation phase…
This trip‟s research will frame our next steps, guiding our brainstorms, prototyping, and finally our decisions for product features and functions.
Goal of this visit

Who We Met:
We spoke with many stakeholders to understand needs and be inspired. We interviewed in context, for extended amounts of time. We visited 6 hospitals, meeting with directors, doctors, nurses, parents, and technicians.

Insights + Opportunities
What we learned
SLIDE 6
Insight: Confusing incubators cost hospitals
SLIDE 7
Insight: Confusing incubators cost hospitals
A district hospital has 5 incubators, but does not use any of them because the staff is afraid and confused by technology. Dhulikel Hospital nurse could not use built-in alarms because she can not read the German instructions. Scheer Hospital nurse did not use the humidity function controls because it was confusing to her. Maternity hospital experience with extensive maintenance needs of certain incubators cost the hospital money instead of enabling care.
SLIDE 8
Insight: Difficult to maintain incubators disables the NICU
SLIDE 9
Insight: Difficult to maintain incubators disables the NICU
Repair times are often excessive. At Teaching Hospital an incubator was broken for one year until the biomedical engineer could travel to Delhi for a 50 rupee part. Several hospitals have no set budget for maintenance, and accessing any funds is time consuming. Complicated designs hinder maintenance for less experienced biomedical engineers and may require unavailable tools.
SLIDE 10
Insight: Shortcomings offer opportunity for improvement in functionality
SLIDE 11
Insight: Shortcomings offer opportunity for improvement in functionality
Lack of appropriate sensors Teaching Hospital NICU‟s do not have the ability to monitor apnea (leading cause of incubator death) Need for multi-dimensional portability Premature baby in Dhulikel was carried outside from delivery room to NICU in winter Babies can die in transit to Kanti for a referral, wrapped in blankets--they could be saved with access to a transportable incubator. Lack of accommodation for basic procedures Most hospitals could not weigh babies inside the incubator; at Scheer this meant premature babies were removed from incubators, and at Dhulikel babies went un-weighed for days at a time.
SLIDE 12
Insight: Donated incubators often present difficulties
SLIDE 13
Insight: Donated incubators often present difficulties
Antiquated temperature probe frequently detaches from skin in Kanti NICU, which can lead to overheating babies. Frequent maintenance problems and general unreliability with „Indian Incubator‟ has caused Maternity Hospital to blacklist similar products. Donated incubators often arrive at Teaching Hospital without manuals
- r parts.
SLIDE 14
Insight: Rural clinics present unique needs and constraints
SLIDE 15
Insight: Rural clinics present unique needs and constraints
- Dr. Sikarmi referred a premature baby for incubator treatment.
Without a local incubator the child died 14 days later. “We need to manage locally”; with no local biomedical engineers,
- Dr. Sikarmi is responsible for all repairs. He has little access to
parts, tools and information. 80% of births in Chautara vicinity take place at home. Premature babies sometimes die before reaching the clinic.
SLIDE 16
From these observations we began to understand the most critical user needs, and develop an understanding of ideal traits that we call design principles…

The field team will share what they have learned with
- ur home teams. Additional synthesis, brainstorming,
and prototyping sessions will take place over then next 10 weeks.
Next Steps:
SLIDE 21
Also, we have identified many technical questions to be answered through medical literature. Just to name a few…
How accurate does it need to be for temperature measurement?
What‟s the complete range for temperature that you‟d want?
What‟s the best location for the temperature probe? What‟s the best level of humidity? How does that change as the baby
develops?
Research apnea monitors.
