A mechanical model of the respiratory system demonstrates the various components involved in breathing mechanics. This model includes the lungs, diaphragm and rib cage; each is vital to normal human breathing. Accurate representation of the volumes and pressures present in the body are essential to an effective model. The current model used in the BME department is not anatomically accurate; therefore, has limited educational value.
This project aims to improve the current “balloon in rigid cylinder” model used in RIT’s Systems Physiology Dynamics and Controls laboratory. The end goal is to prototype a device possessing physiologically relevant lung capacities and flow rates, as well as simulate accurate diaphragm and rib cage movements during various breathing patterns. It is expected to maximize ease of use. A budget of $250 and utilization of PASCO hardware for pressure and flow rate measurement is highly recommended. For preliminary information regarding this project see our Project Readiness Package.
Use CasesAs can be seen below, some potential stakeholders include biomedical engineering students, the biomedical engineering department, RIT and the medical community. Some additional stakeholders include MSD team 16084 and Dr. Bailey.
Project Goals and Key DeliverablesThe end goal for this project is a physiologically accurate mechanical model of a human lung for use in a biomedical engineering lab. In terms of physiologically relevance, the model will resemble the anatomical structure of the parties involved in the respiratory system. This includes the lungs, diaphragm, and ribs. In regards to model use in lab experiments performed by students, the measurements obtained for air flow rate, pressure within the lungs, and intrapleural pressure should be relevant and consistent as defined by their respective values presented in course texts.
At the end of the project, the customer will be provided with a minimum of one working lung model prototype. Also, this MSD team will produce a technical paper, poster, and all design documents.
