Creating a comfortable working environment for cath lab physicians

Abstract

This project is about developing a solution for cath lab physicians. A cath lab physician is a medical doctor, with a background in cardiology, neurology, electro physiology or radiology, who performs cath lab procedures. A cath lab procedure is a minimal invasive procedure in which a catheter is brought into the body of a patient via a small incision. Cath lab physicians suffer from injuries due to the heavy physical workload of their job. The lead apron they wear to protect themselves against the radiation used during the procedures, in combination with long periods of standing, are the main cause of these injuries. An analysis is performed to get more insight in the nature of the injuries and of the environment of the physicians. To start prototyping in an early stage, a short ideation phase took place directly after the analysis. As a result, this phase brought requirements, wishes and concluded with two design directions. A stool with some new features was the best solution. This stool was designed to support the user. The seat will prevent the injuries on the legs while the integrated sternum support reduces the forces in the back muscle. A test was performed to validate the effect of the sternum support. The test shows a reduction between 10% and 15% of the tension in the back muscle. Further research will have to show if the use of the designed solution will actually prevent hernias in the future.
