Project Specification
Pulse oximetry measures peripheral oxygen saturation (SpO2). It provides a real-time, continuous assessment of arterial haemoglobin saturation, and can be used to monitor patients at home. However, the technology has several limitations that can affect the system accuracy and reliability. As part of this project you are expected to work on the design, analysis and test of an oximeter based on an integrated biosensor module. The MAX30102 is a high-sensitivity pulse oximeter and heart- rate (HR) biosensor module that includes internal LEDs, photodetectors, optical elements, and low- noise electronics with ambient light rejection, providing a complete system solution to ease the design-in process for mobile and wearable devices. Recently, an open source pulse oximeters for COVID-19 was reported based on a similar module (Metcalfe et al. 2021).
Criteria
The general criteria are listed above and you must also refer to the rubric published on myLearning for information about expectations, particularly for presentation. Below is some more specific information.
Introduction
The specification is for SpO2 and HR measurement and so you will need to research or review your knowledge on the physical principles, and provide some description of the signals and their sources, as well as identify the factors that affect the signals.
Materials and Methods
You have to design a system based on MAX30102 module and Arduino platform capable of measuring both heart rate and SpO2 content, taking into account the patients needs.
You will need to explain the system architecture, firmware, and all circuits in this section, including probe design.
Results
Present the results of the prototype testing, including the assessment of the accuracy and reliability of the proposed system.
Discussion and Conclusions
This must be evaluative and critique the circuit for the application. You will need to
- Discuss the design process with reference to user needs, and considering other critical issues, such as calibration, optical interference, signal artifacts, powering, safety concerns
Answer the following questions:
Q: Is the proposed system actually suitable for the application? Q: How different could they be given the resources available?
- Discuss the medical device certification process with reference to accuracy standards, medical device directives or regulations
- Include some suggestions for improvement, g. considering the pulse oximeter market trends and opportunities
Learning Outcomes
All learning outcomes will be assessed:
LO1 Specify electronic devices to carry out clinical measurement, diagnosis and / or treatment LO2 Simulate and analyse electronic circuits using commercial software.
LO3 Generate prototypes of and test electronic circuits for a range of medical devices LO4 Design, procure or manufacture and test printed circuit boards
LO5 Communicate the outcome of the design process of an electronic device in writing, with reference to user needs and medical device directives or regulations.
Feedback will be provided within 15 working days of the main report submission date, and it will address criteria 1-5. .
