Abstract

MINI VENTILADOR PULMONAR MECâNICO PNEUMáTICO, trata-se de um equipamento destinado à ventilação artificial em caso de insuficiência respiratória, sendo concebido num monobloco de tamanho pequeno, que o torna muiito mais resistente, fácil de montar, com custo de fabricação reduzido e sem espaços vazios, onde normalmente se acumulam detritos ou poeira, facilitando possível contaminação, sendo seu sistema de ciclagem composto por apenas uma peça móvel, que é um diafragma de borracha com desenho especial, com uma parte flexível central, onde no centro de sua face inferior se destaca um relevo em forma de anel, que veda ciclicamente o orifício de entrada do gás da fonte, por oposição, sem atrito por deslizamento em qualquer ponto, o que evita o desgaste com o funcionamento, uma mola helicoidal apoiada em sua face superior dentro de uma pequena câmara (2,5 cm<B>^ 3^<D>), cuja entrada e saída de gás se fazem por apenas uma válvula de agulha que controla as duas fazes do ciclo respiratório e conseq³entemente a freq³ência do aparelho, apresentado como características especiais a geração de uma onda quadrada com alta resposta de freq³ência com o consumo de um pequeno volume de gás (volume da câmara por ciclo); trata-se portando de um equipamento altamente confiavel e seguro.
