Desenvolvimento de dispositivo para fixação de sonda nasoenteral com abordagem interprofissional: relato de inovação tecnológica

Objective: To report the development process for a nasoenteral tube securing device. Methods: A technological innovation report study conducted between September and December 2024 during and Entrepreneurship Marathon, according to the 11 stages for the design of health products. The prototype was made with polylactic acid and subjected to an exploratory test on a realistic silicone doll. The following aspects were evaluated by means of direct observation: adherence, tube stability, response to gradual manual traction, structural integrity and securement for 72 hours under different orientations and action of gravity. Results: Seven alternatives were constructed, selecting and refining one of them. The prototype remained adhered to the simulated model and kept the tube in position for 72 hours, presenting no full detachment, visually perceptible displacement or structural damage in the conditions evaluated. Gradual manual traction did not produce immediate tube release. The assessments were qualitative, without resorting to a dynamometer, standardized repetition or tests in human beings. Conclusion: The study developed a functional prototype for a nasoenteral tube securing device by means of tridimensional modeling and printing on polylactic acid. The conception and simulated test process was documented.
