Currently, a basic balloon and latex membrane model is being used to represent the lungs, and diaphragm, respectively for classroom instructional purposes. While they demonstrate respiratory mechanics, the models have a short lifespan and do not display alveolar and intrapleural pressure changes. Further, current models do not accurately depict the anatomical scaling of the lungs with respect to the thoracic cavity.
Our goal is to design and build an adequate mechanical respiratory model for class instruction purposes. This model should demonstrate relative pressure differences between alveolar and intrapleural spaces. It must further demonstrate the expansion of the thoracic cavity from the rib cage as well as the diaphragm, thereby displaying a 3-D expansion. The scaling of the lungs relative to the size of the thoracic cavity enclosure should be more anatomically correct. The device must be portable and small enough to use with a document camera.
Having met with our clients and clarified our project requirements, the team spent last week brainstorming and sketching design ideas. This week the team will decide between the three most feasible designs and start preparing the PowerPoint presentation. Throughout the brainstorming process, the team has been researching materials to be used for prototype construction.
