Resumen de Simulación, optimización y parametrización de una cámara hiperbárica flexible de 6 ata de bajo coste. Propuesta de fabricación industrial
The objective of the present thesis was to carry out an investigation that would allow innovating the hyperbaric technology with the development of a flexible portable hyperbaric chamber that works in a pressure gradient of 1.5 ATA up to 6 ATA. This objective was intended to achieve through the study of materials and the technical configuration of a model to be industrialized. It was intended to study both components and the whole, that could be used for both hospital and sports use, as well as in public or private sectors, which required the device complies with the regulations for validation of medical devices and pressure vessels, both internationally and the European Union. The design and study of the model has validated the main objective and has ensured compliance with these and other international regulations, such as the German and Australian.
Among the different hypotheses proposed for the dimensioning of the single-seat hyperbaric chamber, in order to meet the objective of maximum lightness, a study of materials was carried out in function of their technical properties vs. lightness, cost and reliability for outdoor use, hardness and working conditions. It was intended that those devices were capable of withstanding pressures of more than 30 bar (exceptional charge of homologation), which are compatible with oxygen, antistatic and resistant to UV radiation (for external use), light and economical.
The hypotheses put forward concluded that the spinning direction conditioned the properties of the element and the transmitted tensions, allowing to choose the best yarn arrangement of the chamber body, as if the superimposition of thinner fabrics and the same specifications enlarged the properties of the element and of the set. That subjecting the hyperbaric chamber to exceptional load requires a fastening element to prevent the elements from being dismissed during the operation. That it is not true that a smaller thickness of the tissues maintains the linearity in the results The use of geometric, kinematic and dynamic similarity, as well as the introduction of curves for the treatment of dysbaric accidents, allowed us to accurately determine the simulation of the materials when the hyperbaric chamber, both its components and the assembly, were subjected to pressure.
Other objectives were to ensure that the technology designed for the application of hyperbaric oxygen therapy would not exceed the minimum cost of the market-quality flexible portable hyperbaric chamber (1.3 ATA) not suitable for HBOT use. The objective figure set for the industrialization of the developed structural model was to be between € 12,000 and € 15,000. The technical model obtained, meets the objective of the study, not only economically, but also in lightness and availability.
The result of the investigations carried out has allowed obtaining by means of finite elements a flexible hyperbaric chamber patented by means of registration of utility model.
The analysis of the current state of the art allows affirming that the technique of simulation by finite elements is consolidated as the best alternative to reduce the costs of industrialization of complex devices like the one of the present thesis.
