Abstract

Patente de Invenção: <B>"DISPOSITIVO DE GATILHO DE VENTILADOR APERFEIçOADO"<D>. Um dispositivo aperfeiçoado para proporcionar uma respiração engatilhada para o paciente compreendendo um ventilador dotado de um tubo que fornece um fluxo de um gás e outro tubo que envia o gás a uma válvula de exalação, um tubo endotraqueal que está em comunicação com os pulmões do paciente, e um conector para conectar o tubo de fornecimento a partir do ventilador ao tubo endotraqueal, o conector tendo uma câmara, e tendo uma válvula de duas vias, a válvula de duas vias tendo uma válvula de segurança de inalação e uma válvula de segurança de exalação. A parede do conector pode adicionalmente incluir uma abertura para conexão a um transdutor de pressão. O volume da câmara do conector está entre cerca de 1,0 cm a 1,3 cm e a válvula de exalação é seletivamente movida a partir de sua posição aberta para a sua posição fechada quando o transdutor de pressão percebe uma redução na pressão dentro da câmara entre cerca de 0,25 cm de água e 2,0 cm de água e onde a válvula de exalação é movida a partir de sua posição fechada para a sua posição aberta após um período de tempo predeterminado.
