Resumo
Introdução: O plasma rico em plaquetas (PRP) é preparado a partir de uma pequena quantidade de sangue e tem sido utilizado nos processos de cicatrização considerando a presença de fatores de crescimento, permitindo atuar de forma ampliada, nos processos regenerativos. A falta de padronização nos diversos ensaios clínicos referentes às normatizações das centrífugas, “força G e tempo de centrifugação” determina resultados diferentes. Tal observação motivou a pesquisar estudos na busca de padrões que extraiam o máximo de plaquetas em um preparado de PRP. Objetivo: Desenvolver um modelo de utilidade de uma centrífuga padronizada para obtenção de Plasma Rico em Plaquetas (PRP) e hemoderivados. Métodos. O estudo foi aprovado pelo Comitê de Ética em Pesquisa, realizaram-se buscas de anterioridade e desenhos gráficos para identificar cada uma das partes do instrumento, e posteriormente realizado o pedido de patente de uma centrífuga com padrões definidos: correspondente à realização de uma centrifugação com uma força de 200 g por um período de 10 minutos. Resultados: Foi desenvolvido um desenho industrial de uma centrífuga portátil, de fácil manuseio, com parâmetros pré-determinados. A centrífuga tem um caráter universal, uma vez que a mesma se adapta a vários kits de PRP que se apresentam no mercado. Conclusão: O desenho industrial da centrífuga foi encaminhado ao NIT para solicitação da patente (tipo modelo de utilidade) que visa facilitar o manuseio e preparação de tal tecnologia aos profissionais de saúde que lidam e a utilizam no processo de regeneração tecidual.
Introduction: Platelet-rich plasma (PRP) is prepared from a small amount of blood and has been used in the healing processes, considering the presence of growth factors and acting in regenerative processes. The lack of standardization in the various clinical trials related to the centrifugal standardization: "force g and centrifugation time" can provide a range of different results. This observation motivated to investigate studies in the search for the patterns that are able to extract maximum platelets in a PRP preparation. Objective: Develop a utility model of a standardized centrifuge to obtain platelet-rich plasma (PRP) and blood products. Methods: The study was approved by the Research Ethics Committee. The search for anteriority and graphic designs were carried out to identify each part of the instrument, followed by the patent application for a centrifuge with defined standards corresponding to the performance of a centrifugation with a force of 200g for ten minutes. Results: An industrial design of an easy-to-use portable centrifuge with predetermined parameters was developed. The centrifuge is considered universal since it adapts to several PRP kits that are available on the market. Conclusion: The industrial design of the centrifuge was referred to the NIT for patent pplication (utility model type), which aims to facilitate the handling and preparation of such technology by health professionals who use it in the process of tissue regeneration.
