摘要:
Patent Summary for: Antibolus Control Process and Corresponding Device. The invention relates to a knob displacement control method of a push-type pump, the pump comprising a housing (100) a syringe cradle (200) in which a syringe (400), a knob (300) movable relative to the housing (100) and can be driven in translation parallel to the longitudinal axis of the syringe by drive means, clutch means (310, 350, 351) to clutch or debut the knob (300) over the drive means. In the process of the invention, the knob (300) is initially desolidarized from the drive means, which allows for manual displacement syringe, and the presence or absence of a contact between the knob (300) and the syringe head (401) is determined. If the button is not in contact with the syringe head, it will be manually advanced toward it. as long as the button contacts the syringe head, the advance movement of the button is stopped. locking the advance movement of the knob is only triggered at the beginning of operation, the knob not being in contact with the syringe head. Contrary to the prior art, it is not the syringe plunger that is blocked, but it is the movement of the knob that is stopped as long as there is contact between the syringe and the knob.resumo da patente de invenção para: processo de controle antibolus e dispositivo correspondente. a invenção se refere a um processo de controle do deslocamento do botão de uma bomba de tipo empurra-seringa, a bomba compreendendo uma caixa (100) um berço de seringa (200), no qual é colocada uma seringa (400), um botão (300), móvel em relação à caixa (100) e podendo ser acionado em translação paralelamente ao eixo longitudinal da seringa por meios de acionamento, meios de embreagem (310, 350, 351) para embrear ou debrear o botão (300) sobre os meios de acionamento. no processo da invenção, o botão (300) é inicialmente dessolidarizado dos meios de acionamento, o que permite seringa deslocamento manual, e a presença ou ausência de um contato entre o bot
