Objective: To describe the construction of a low-cost simulator of chest drainage for the training of undergraduate medical students. Methods: The model was conceived in 2014 by members of the Tutorial Education Program - UNIFOR. It was tested by 10 specialists and approved for application in four editions of a theory and practice course on invasive procedures with medical students from different universities. To evaluate the simulator and its performance, semi-structured questionnaires and checklists were applied. Data were analyzed in the Statistical Package for the Social Sciences v. 22, using descriptive statistics. Results: A commercial mannequin was used to build the model. An 8 x 8 cm square cut was made in the lateral wall of the chest. Inside this region, EVA sheets (simulating skin and intercostal muscles), foam padding (subcutaneous tissue) and transparent PVC sheet (pleura) were placed. In the inner part of the mannequin, a wooden structure containing two ribs was constructed and a plastic cup containing red-dyed water was placed between the two ribs. The complete model had an initial cost of R$ 81,00/US$ 21,00. The medical specialists agreed (100%) that it can be used for undergraduate teaching. During the course on invasive procedures, 129 students performed the procedure; 64.3% of them were able to correctly insert the drain and 79.1% connected it to the drainage system. Despite of the high percentage of errors in basic initial steps, the students were able to execute the technique satisfactorily. Conclusion: The low-cost chest drainage simulator was easy to access and to reproduce in universities, which makes it an important tool for teaching.
