Title: Biomedical design projects developed around OEM devices


1
Biomedical design projects developed around OEM
devices
  • Jean-Michel I Maarek
  • Department of Biomedical Engineering
  • University of Southern California
  • Los Angeles, CA 90089
  • jmaarek_at_usc.edu

2
Senior projects design course
  • BME 405L Senior Projects Measurements and
    Instrumentation
  • 15-week course with laboratory organized in 3
    hours of classroom time 3 hours of laboratory
    time per week
  • Offered twice a year to accommodate all BME
    seniors ( 50 students year)
  • Enrollment 18 students in Fall 06 and 27
    students in Spring 07

3
Goals of Senior Projects course
  • Course goals to integrate applications of
    computer programming, signal transduction, data
    acquisition, data analysis, and signal processing
    in the design of medical and laboratory
    instrumentation
  • LabVIEW standard in academic and industrial
    environments for data acquisition, interfacing of
    instruments, data analysis, and graphic user
    interface
  • Students apply LabVIEW as a tool for the design
    of computer-based medical virtual instruments

4
Topics addressed in BME 405L
  • LabVIEW programming basics
  • Software architectures
  • Development of software requirements and use
    cases
  • Properties of signals and data acquisition
  • Instrument control
  • Graphic user interface
  • Light, pressure, and temperature transducers

5
Format
  • Time divided between instructor-led presentation
    (1/3 time) and student activities (2/3 time)
  • Activities to develop programming skills and
    practice concepts discussed with instructor
  • Instructor and teaching assistant roam the room
    during activities and assist students in their
    work
  • Six canned laboratories cover basics of data
    acquisition and instrument control, static and
    dynamic calibration of pressure, temperature, and
    light transducers, and a virtual frequency
    analyzer
  • 8 week project to develop a computer based
    medical monitor using an OEM device

6
Term project with OEM device
  • OEM device Ipod (Nonin) pulse oximeter and M2600
    NIBP monitor (Colin Medical)
  • Programmers manual
  • Serial (RS 232) control and communication for
    implementation of medical monitor with several
    modes of measurement or signals
  • Graphic user interface
  • Data storage

7
Functional requirements from use case
8
Project deliverables
  • LabVIEW program
  • Graphic User Interface
  • Demonstration (rated by other group of students)
  • Design report

9
Conclusions
  • OEM device provides realistic experience in terms
    of technical integration, use of technical
    documentation
  • Use case entices students to think about use of
    product by others. Graphical user interface also
    reflects emphasis on users
  • Favorable comments from industrial advisory board
    and high student evaluation marks but no formal
    evaluation
