Full description

This clinical investigation addresses the performance of a re-designed (updated) speaking valve with Heat and Moisture Exchangers (HME) for tracheotomized patients (project development name 'TW', commercial name 'DualCare'). Study participants trial the new device for 2 weeks after which they can choose to discontinue using the device or continue in the 3 month follow-up part of the study. Clinical feasibility is assessed using structured questionnaires addressing voice and speech, quality of life, breathing, swallowing, olfaction, sleeping, and respiratory symptoms. This is an exploratory, observational study and no specific hypotheses have been formulated.
