Background: Vascular access is the procedure performed with greatest frequency in hospitalized patients. Simulation models are intended to minimize complications and combine technical and theoretical knowledge, offering a safe environment for training health professionals that avoids the ethical dilemmas of conducting initial training with patients. Many different training dolls have been developed to achieve this objective, but their high cost means they are not universally available, and it is common for unqualified health professionals to perform procedures on patients with no previous practice. Objective: To develop a low-cost educational model for teaching and training peripheral vascular access. Method: Peripheral access routes were reproduced using a polyethylene foam noodle and infusion kits, each with one extremity sealed off and the other connected to one of two 500 mL packs of saline, dyed red or blue. The packs were hung on a metal stand. Results: The structure chosen for the model was similar to a simplified version of the anatomy of the forearm. The model proved to be practical for puncture and, because of its length, the same model can be punctured multiple times, facilitating training. Conclusions: The model proposed here enables training of peripheral vascular access and is a low-cost option that can be used for educational purposes.

Resumo Objetivo: Desenvolver um modelo de baixo custo, com fins educacionais, para treinamento de punção ecoguiada. ARTIGO DEMétodo: O fantasma é feito com uma adaptação de gel balístico utilizando água, gelatina e glicerina. Para os vasos sanguíneos, são utilizados tubos de látex (drenos Penrose) para veias e politetrafluoretileno (PTFE) para artérias. Estes são preenchidos com gel incolor e fixados no manequim. Por fim, deve-se refrigerar o molde já com a mistura, por 6 horas. Resultados: No modelo proposto foi possível treinar habilidades de punção ecoguiada. As imagens obtidas utilizando o fantasma são de alta qualidade quando comparado com a anatomia sonográfica normal. Conclusão: Este modelo é uma alternativa didática e viável economicamente para a realização de treinamento de punção ecoguiada.Descritores: ultrassonografia de intervenção; treinamento por simulação; procedimentos cirúrgicos vasculares; ecogenicidade.Summary Purpose: To develop a low cost model, with educational purposes, for ecoguide puncture training. Methods: The phantom is made with ballistic gel adaptation using water, gelatin and glycerin. For blood vessels, latex tubes are used (Penrose drains) to veins and polytetrafluoroethylene (PTFE) for arteries. These are filled with colorless gel and fixed on the mannequin. Finally, cool the mixture in the mold for 6 hours. Results: In the proposed model was possible to train ecoguied puncture skills. The images obtained using the phantom are high compared with normal sonographic anatomy. Conclusion: This model is an educational alternative and economically viable for conducting ecoguied puncture training.
