Abstract

a invenção se refere a um aparelho de tratamento médico compreendendo um conjunto de tubo 20, uma bomba peristáltica 6 para transportar fluido e um aparelho de monitoramento 15 para monitorar a oclusão dos elementos de deslocamento positivo 13a, 13b da bomba peristáltica. além disso, a invenção se refere a um conjunto de tubo 20 para um aparelho de tratamento médico, e a um método para monitorar a oclusão dos elementos de oclusão de uma bomba peristáltica para transportar um fluido para um aparelho de tratamento médico. a invenção se baseia no fato de que a oclusão dos elementos de deslocamento positivo 13a, 13b da bomba peristáltica 6 é monitorada com o objetivo de monitorar o fluxo de fluido na linha de mangueira 5. para tanto, a resistência elétrica ou uma variável que corresponde à resistência elétrica é medida entre um primeiro e um segundo eletrodos 16a, 16b, o primeiro eletrodo 16a sendo disposto na linha de mangueira 5 a montante dos elementos de oclusão 12 da bomba peristáltica 6 e o segundo eletrodo 16b sendo disposto na linha de mangueira a jusante dos elementos de oclusão, de modo que um contato elétrico seja criado entre o primeiro e o segundo eletrodos 16a, 16b e o fluido que flui na linha de mangueira 5. os eletrodos 16a, 16b são, de preferência, partes componentes integrais de uma peça de conexão 10, por meio da qual o segmento de mangueira 5a a ser inserido dentro da bomba peristáltica 6 é fixado na forma de um laço.
