Abstract

FILTRO SANGUINEO QUE CONSTA DE UNA SECCION DE SEPARACION DE BURBUJAS QUE INCLUYE UNA CAMARA CILINDRICA PARA PERMITIR QUE LAS BURBUJAS SE SEPAREN DE LA SANGRE, UN RESPIRADERO PARA DESCARAGA DE AIRE EN UN EXTREMO SUPERIOR DE LA CAMARA Y UN CONDUCTO DE ENTRADA QUE SE EXTIENDE HORIZONTALMENTE DE LA CAMARA PARA INTRODUCIR SANGRE EN LA MISMA. EL FILTRO INCLUYE TAMBIEN UNA SECCION DE FILTRADO SITUADA POR DEBAJO DE LA SECCION DE SEPARACION DE BURBUJAS, INCLUYENDO UNA SALIDA Y UN EXTREMO INFERIOR PARA DESCARGA DE LA SANGRE Y UN FILTRO SITUADO ENTRE LA ADMISION Y LA SALIDA. EL EJE DEL CONDUCTO DE ADMISION SE EXTIENDE PARALELO A UNA TANGENTE A LA CAMARA CIRCULAR EN LA CONEXION ENTRE LA CAMARA Y EL CONDUCTO DE ADMISION, Y UNA PARTE DE ENTRADA ESTA SITUADA ENTRE EL CONDUCTO DE ADMISION Y LA CAMARA PARA DEFINIR UN PASO QUE UNE EL CONDUCTO DE ADMISION A LA CAMARA, POR LO QUE LA PARTE DE ENTRADA DIRIGE LA SANGRE PROCEDENTE DEL CONDUCTO DE ADMISION PARA QUE FLUYA LAMINARMENTE Y SE UNA CON EL FLUJO TURBULENTO DE LA CAMARA. EL APARATO TIENE UNA GRAN CAPACIDAD DE EXTRACCION DE BURBUJAS DADO QUE AL FILTRO LLEGAN MUY POCAS BURBUJAS PUESTO QUE LA SANGRE QUE SE INTRODUCE NO ALTERA EL FLUJO TURBULENTO DE SANGRE EN LA CAMARA.
