Abstract

aparelho médico e método para detectar um fluxo de fluido através de um conduto de fluido de um aparelho médico. a presente invenção se refere a um aparelho médico, em particular um aparelho de diálise peritoneal automatizada (apd). também são fornecidos métodos associados de uso ou controle do aparelho médico. um aparelho médico, conforme descrito neste documento, pode incluir um alojamento tendo uma região de recebimento e um estojo adaptado para ser recebido na região de recebimento. uma bomba, como uma bomba de cabeçote duplo, pode ser usada para aplicar uma pressão positiva ou negativa através de um ou mais condutos, a fim de fazer com que um movimento de uma membrana mova um fluido para dentro ou para fora de uma cavidade do estojo. outros aspectos e modalidades da presente invenção se referem a: medir um volume de fluido usando um sensor de onda sonora; aquecer fluido contido dentro do estojo; acionar portas usando pressão positiva e negativa aplicada por uma bomba; e fornecer indicadores visuais para guiar a conexão de um tubo a um orifício correspondente.medical apparatus and method for detecting a flow of fluid through a fluid conduit of a medical apparatus. The present invention relates to a medical device, in particular an automated peritoneal dialysis (APD) device. Associated methods of using or controlling the medical device are also provided. A medical device as described herein may include a housing having a receiving region and a case adapted to be received in the receiving region. a pump, such as a double head pump, can be used to apply a positive or negative pressure through one or more conduits in order to cause a movement of a membrane to move a fluid into or out of a cavity in the case. other aspects and embodiments of the present invention relate to: measuring a volume of fluid using a sound wave sensor; heat fluid contained inside the case; operate doors using positive and negative pressure applied by a pump; and provide visual indicators to guide the connection of a pipe to a corresponding hole.
