Abstract
desenho de ponta de tratamento focal e método para otimizar a transferência de calor através de fluidos e gases em baixa temperatura. uma ponta de tratamento focal (ftt) para controlar a taxa de evaporação e proporcionar distribuição direcionada de gases liquefeitos em baixa temperatura para contato com o tecido vivo, inclui um corpo curvo. quando preenchido com gás liquefeito, o dispositivo isola o gás de fontes de perda de calor, como o ambiente circundante. o dispositivo pode controlar a taxa de evaporação do gás liquefeito no local de tratamento. a taxa de evaporação controlada afeta a taxa de transferência de calor do tecido tratado, permitindo tempos de exposição controlada e resultados desejados. o dispositivo pode ser usado com várias pontas de aplicação para definir melhor a área do tecido alvo a ser tratada, minimizando os danos colaterais ao tecido circundante e isolando o gás dentro do corpo curvo e concentrando a transferência de calor na área de tratamento desejada. o dispositivo pode usar materiais transparentes que tornam o tratamento visível para o operador enquanto o gás liquefeito está evaporando.
