Abstract
Patente de Invenção:<B>"CâMARA DE PROCESSAMENTO DE SANGUE CONTRABALANçADA COM LìQUIDO LIVRE DE SANGUE"<D>. Sistemas e métodos de processamento de sangue são divulgados. Uma câmara de processamento (14), girando em um elemento rotativo, inclui um primeiro compartimento (38) e um segundo compartimento (40). Sangue é transportado para o primeiro compartimento (38) para separação centrífuga em componentes. Um líquido livre de sangue ocupa o segundo compartimento (40) para contrabalançar o primeiro compartimento (38), durante rotação no elemento rotativo. Em uma segunda concretização, o segundo compartimento (40) é servido por um único acesso de fluido. Antes do uso, o acesso único é acoplado à tubulação, através da qual um vácuo é aspirado para remover ar do segundo compartimento (40). Enquanto o vácuo existe, a comunicação está aberta entre a tubulação e uma fonte de líquido. O vácuo extrai o líquido no segundo compartimento (40) através do acesso único, assim, escorvando o segundo compartimento (40) para uso.
