Team Vision for System-Level Design PhaseThe goal of this design phase was to create a functional decomposition, update benchmarking, begin a feasibility analysis, as well as begin concept selection based on the information generated from the information gathered.
Purpose of Vehicle
- Transport People and Equipment
- Provide Life Support, and Monitoring for a Neonate
- Incorporate a dependable way to sanitize equipment after use
- Provide an easily serviceable vehicle in Honduras

The current CPAP (continuous positive airway pressure) machine, The Neopuff is affordable, functional and already used in Honduras. As a result it was determined to integrate the Neopuff into the emergency vehicle instead of introducing a new, costly ventilator. However, a modification was suggested by the customer to improve performance.
The Modification:Currently the Neopuff requires constant human interaction to control the pressure delivered to the infant. The modification will include the addition of a settable mechanical attachment to the gas outlet tubing that will provide pressure control without the need for constant human correction. The functionality of the equipment will not change, but will become more automated allowing for less monitoring of the device.
As this modification has just been introduced to the project after the trip to Honduras in early October, no concept designs or prototypes have been created yet.
Outputs and DestinationConcept designs for NeoPuff modification coming soon!
Feasibility: Prototyping, Analysis, Simulation
PurposeCalculations for the total power required and the power that could be provided from an inverter were performed to ensure adequate power for all systems:
With 2 incubators, 2 monitors, and 2 ventilators (1 for each infant), using an inverter is feasible.

Risk AssessmentChoosing products and adding a medical professional in the back of the vehicle changed the Risk Assessment from previous scenarios. Click Here to view our new updated risk assessment document.
Highest Risks Include:
- Equipment Failures
- Injuries to infants resulting from transport
- Medical professional is not secured during transit
- Equipment needed is not present during transit
- Incubator becomes unsecured during transport
Plans for next phase
- Refine internal layout design
- Design large equipment securements
- Investigate and prototype options for CPAP modification
- Develop more extensive cost profile
- Prototype electrical systems
