Abstract

aparelho com base em bomba peristáltica e método para a dispensação controlada de fluidos. a presente invenção envolve uma bomba peristáltica rotativa e um método associado que emprega o relaxamento da pressão na tubulação flexível entre o rotor e o estator da bomba para restaurar o rotor a um ângulo de partida enquanto uma válvula na saída da bomba é fechada para evitar o progresso de fluido através do sistema. três implementações diferentes da bomba e do método são apresentadas, incluindo alternar o estator, alternar o rotor e retrair os rolos loucos do rotor no rotor para aliviar a pressão na tubulação flexível. um controlador garante a comutação e a temporização apropriadas da válvula e do rotor da bomba. a bomba e o método associado são direcionados para a dispensação precisa de fluidos farmacêuticos em recipientes, incluindo recipientes mantidos em ninhos de recipientes.
