Desenvolvimento de biomodelo fetal no acompanhamento de gestante com deficiência visual

Abstract

The concept of maternal-fetal attachment (MFA) is used in the literature to describe the quality of the pregnant woman's relationship with the fetus, based on cognitive representations that include the mother's imagination. An important ally in this process is ultrasound (USG), allowing the formation of a specific image with physical characteristics that make it possible to understand and define the fetus as an autonomous and real being. For women with visual impairment, however, the experience with US is incomplete and the inclusion of assistive technology (AT) becomes necessary to benefit this scenario. In this process, the construction of a physical biomodel through Additive Manufacturing (AM) has increased the perspectives of development and assistance to this group, concentrating the objectives of this research, which aims to develop a fetal biomodel by Additive Manufacturing to favor the inclusion of assistive technology in the monitoring of pregnant women with visual impairment. The present study was developed in the laboratory of three-dimensional technologies (LT3D) of the Nucleus of Strategic Technologies in Health (NUTES), located at the State University of Paraíba (UEPB), respecting ethical perspectives through validation by the research ethics committee. This is an action-research study, subdivided into three major methodological stages that correspond to the major phases of the process: Acquisition of fetal images; Digital development; and Device manufacturing. In order to achieve the objectives of this proposal, the process of Modeling by Fusion and Deposition (FDM) and the material polylactic acid (PLA) were used. The final physical biomodel was characterized by high definition and touch perception with detailing of anatomical structures of the face, in addition to resistance and lightness.
