Project Objective Statement
Our goal is to deliver a functioning physical model of systemic circulation which, when used in conjunction with the P16080 heart pump, will be used as a teaching tool that will allow students to validate mathematical models of the circulatory system from Chapter 5 of “Quantitative Human Physiology” An Introduction by Joseph Feher. The model will ultimately enhance students' understanding of the circulatory system by making it possible for them to analyze both normal and pathological conditions through the measurement of relevant parameters, such as pressure and flow.
Goals for this review
- Receive feedback from attendees
- Identify obstacles between current state and the desired end goal
- Create an action plan to address each issue
Overall, we hope to use the information gathered here and the feedback received after this review to proceed with confidence to the second phase of our project.
- Current state:
- No current experiment is being conducted in the BIME 492 lab that explicitly studies the circulatory system
- Only available option is having students as the models
- The circulatory system cannot be studied independently from the respiratory system
- Cannot study anything other than normal, healthy function
- Desired state:
- A physical model of the circulatory system, which includes systemic circulation and heart pump
- Isolates the circulatory system from the respiratory system
- Provide the ability to study both normal and pathological functions of the circulatory system
- Allow students to validate mathematical models they've covered in previous coursework
- Enhance the learning of the students
Other models for benchmarking:
- Dr. Steven Day, Rochester Institute of Technology
- Dr. Schwartz, University of Rochester
- Other Schools
Meetings be will scheduled to assess the applicability of these in our system design. The team is currently reaching out to other schools to see how their needs are being met in terms of a circulatory model for their physiology laboratory courses. The Dr. Day model draws most of its inspiration from the Donovan Mock Circulation Model, which is still used present day by some companies for the FDA testing of their artificial heart devices.
- PASCO: Pressure sensors will allow measurement of pressure/flow across the circulatory system model (TBD).
- Tubing & Fittings: will be used model design and for controlling parameters within the circulatory system. A supplier for these components has yet to be decided, seeing as the characteristics of these components will need to output values similar to those in the human circulatory system (TBD).
- Software: LabVIEW and MATLAB will be used for data acquisition.
