Team Vision for System-Level Design Phase

The 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.

Functional Decomposition

Purpose of Vehicle

Benchmarking

Benchmarking of three different transport incubators considered

Benchmarking Specifications for CPAP or ventilators considered

|Benchmarking Specifications for Vital Monitors, specific monitors have not been chosen to evaluate and so there is no comparison of monitors

Concept Development

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 Destination

Concept designs for NeoPuff modification coming soon!

Feasibility: Prototyping, Analysis, Simulation

Purpose

Calculations for the total power required and the power that could be provided from an inverter were performed to ensure adequate power for all systems: public/Systems Level Design Documents/Feasibility analysis/Inverter feasibility analysis.jpg

With 2 incubators, 2 monitors, and 2 ventilators (1 for each infant), using an inverter is feasible.

Morphological Chart and Concept Selection

Click Here to view our Morphological Chart, and Concept Selections. Initial selections for equipment and design direction were made based on this chart, and can be seen below in Concept Selection. Selected concepts were then analyzed further based on availability in Honduras, cost, and effectiveness at completing the task at hand.

Risk Assessment

Choosing 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:

  1. Equipment Failures
  2. Injuries to infants resulting from transport
  3. Medical professional is not secured during transit
  4. Equipment needed is not present during transit
  5. Incubator becomes unsecured during transport
