Overview of Status of Analysis, Design, Fabrication, Tests, etc.
· Analysis
o The following areas were identified as areas of analysis
§ Fluid Pressure Analysis
· Flow based pressure
§ Fluid Flow Analysis
· Flow rates based on syringe input pressure
§ Toggle Device Force Analysis
· Geometric design based pressure feedback
· Other [Brainstorm]
· Design
o The following areas were identified as areas for design
§ Hand Held Housing
· Must be ergonomic
· Inexpensive
· Single-use
· Must be able to see fluid
· Toggle Sub-Device
o Force sensitive forward control
o Single gear backward control
§ Pressure Sensor
· Has to be reliable
· Has to be easy to calibrate on the go
· Has to read approx. 1000mmHg or more
§ Control Module
· Must give real-time, accurate pressure readings in standard units
· Syringe Volume Selector is preferred but non-essential
· Stand-alone (no connections) is preferred but non-essential
· Must fit a standard syringe size or adaptable to multiple standard syringe sizes
· Fabrication
o NA
· Tests
o The following tests were identified as potential risk assessment tests
§ Reading pressure when injecting an object with water
· Expanding object like a balloon
· Fixed volume test
Accomplishments from Previous Week
· Met with sponsor and defined general design parameters as well as areas of risk
Goals for Next Week (list names after each item). Use specific and measurable objectives
· Risk Reduction
o Brainstorm risk reduction tests to be performed with pressure sensor (EVERYONE)
§ If possible, start analysis for pressure sensor
o Start research pressure sensors appropriate for the application (EVERYONE)
o Setup Gantt Chart with general stages (e.g. analysis, design, fab) (TBD)
o Find MSDS and proper disposal information for materials we will be working with (JAMIE)
o Setup Budget spreadsheet with tentative budget subdivision (e.g. materials, sensors etc.) (MICHAEL)
o Setup Dr. Beal with eDrawings (PAKO)
o Setup report template (RENE)
