Abstract
MÉTODO PARA DESCONEXÃO. A presente invenção refere-se a um método para desconectar duas seções de linha de condução de fluido de um dispositivo médico que são interconectadas de forma destacável, em que uma primeira seção de linha das duas seções de linha tem pelo menos parcialmente uma propriedade elástica. O método compreende os passos de encerrar um volume de fluido nas duas seções de linha, gerar uma pressão reduzida nas duas seções de linha, como um resultado de que deformação elástica a partir de uma posição inicial para uma posição tensionada ocorre dentro e/ou na primeira seção de linha, em que um volume de fluido contido na primeira seção de linha é menor na posição tensionada do que um volume de fluido contido na posição inicial, e separar a conexão das seções de linha, em que o volume de fluido contido na primeira seção de linha na posição tensionada aumenta. Além disso, a invenção referese a um dispositivo médico que é configurado para realizar um método deste tipo.
