Introduction: vibratory devices are used in respiratory therapy in order to facilitate removal of bronchial secretions. A portable hydraulic system incorporating inspiratory and expiratory valves could provide additional advantages over existing ones. The present study describes the invention and evaluation of a new portable medical device able to induce high frequency vibration and allowing respiratory muscle training for patients with respiratory diseases, which has been named with the acronym TriBURTER. Methods: based on conventional methods of bioengineering, a hydraulic device was conceptualized, designed, built, and validated using electronic simulators. In addition, perceptual evaluations of morphology, final prototype design and function were evaluated in both healthy volunteers and patients through specific psychometric scales. Results: a hydraulic device including two unidirectional valves was finally obtained allowing to induce simultaneously a triple effect: mobilization of bronchial secretions, inspiratory muscle training, and expiratory muscle training. Perceptual evaluations showed that the final design is safe, adequate, sufficient and practical. Conclusion: TriBURTER is an innovative hydraulic medical device for respiratory therapy that facilitates drainage of secretions and generates adjustable inspiratory and expiratory muscle loads. The perceptual evaluations of the device showed proper acceptance of use by healthy volunteers and patients in terms of quality and performance. This device is useful for the treatment of respiratory diseases and can be prescribed for both outpatient and domiciliary or hospital settings. MÉD.UIS. 2016;29(2):49-57.
