Abstract: Pectus Vac

Pectus excavatum is a congenital disorder manifesting as abnormal chest wall development which leads to a sunken chest appearance due to an inward growth of the ribs and sternum. This condition is more common in males than females and typically becomes more significantly pronounced during adolescent growth. Complications of pectus excavatum vary from cosmetic appearance to serious conditions stemming from severe chest depression and the resulting pressure on the heart or lungs. Current treatments typically involve surgery to insert a stabilizer bar to reshape the chest wall or non-surgically with a vacuum bell device which we aim to improve on in this project. Currently, with the exception of patient self-reporting, there are no methods for doctors to physically monitor patients’ usage of the vacuum bell which make it challenging for doctors to objectively individualize treatments for each patient. We propose integrating a sensor and a data logger because it facilitates the capability of doctors to monitor a patient’s usage time as well as increasing patient compliance while using the vacuum bell. Objectives of this project are to identify a way to manufacture a modified version and to identify a method to consistently monitor patients’ usage. Research design consists of identifying a manufacturer capable of small-scale manufacturing, converting a single prototype to clinical use products of about one hundred devices, and verifying the quality of the devices. Expected outcomes include successfully establishing contact with a prospective manufacturer to collaborate on manufacturing a sample device, and successfully verifying the quality of the device. Upon successfully meeting objectives, we hope to make treatments with vacuum bells more efficient, scale up manufacturing, and be able to more accurately read and process sensor data.
