Abstract

LOS FILTROS DE INTERCAMBIO DE CALOR Y DE HUMEDAD COMPRENDEN UNA CAPA DE MEDIOS HIDROFOBOS JUNTAMENTE CON UNA CAPA DE UNOS MEDIOS HIDROFILOS. LOS FILTROS PUEDEN USARSE MEDICAMENTE EN EL EXTREMO CORRESPONDIENTE AL PACIENTE DE SISTEMAS DE RESPIRACION ABIERTA CON EL MATERIAL HIDROFILO AGUAS ABAJO DEL PACIENTE EN EL CAMINO DE LA EXHALACION. EL MATERIAL HIDROFOBO IMPIDE EL PASO DE GOTITAS Y DE GLOBULOS DE AGUA, DE LA MANERA CONOCIDA, Y TIENE ADEMAS UN PUNTO DE BURBUJEO LO SUFICIENTEMENTE ALTO COMO PARA APRISIONAR LOS MICROORGANISMOS. EL MATERIAL HIDROFILO APRISIONA AL VAPOR DE AGUA QUE PASA A TRAVES DEL MATERIAL HIDROFOBO Y PERMITE POR CONSIGUIENTE QUE SEA RETENIDA MAS HUMEDAD POR EL FILTRO. ESTA HUMEDAD ES RECOGIDA POR LOS GASES INHALADOS Y SIRVE PARA PROPORCIONAR UNA HUMEDAD ADICIONAL A TALES GASES INHALADOS.HEAT AND MOISTURE EXCHANGE FILTERS INCLUDE A LAYER OF HYDROPHOBIC MEDIA TOGETHER WITH A LAYER OF SOME HYDROPHILIC MEDIA. FILTERS MAY BE USED MEDICALLY AT THE PATIENT'S END OF OPEN BREATHING SYSTEMS WITH THE HYDROPHILIC MATERIAL WATER DOWN THE PATIENT ON THE EXHALATION ROAD. THE HYDROPHOBIC MATERIAL PREVENTS THE PASSAGE OF GOTITES AND WATER BLOCKS, IN THE WAY KNOWN, AND ALSO HAS A BUBBLE POINT ENOUGH HIGH TO ENTRAY THE MICROORGANISMS. THE HYDROPHIL MATERIAL ENTRAPS THE WATER VAPOR THAT PASSES THROUGH THE HYDROPHOBIC MATERIAL AND THEREFORE ALLOWS MORE MOISTURE TO BE RETAINED BY THE FILTER. THIS MOISTURE IS COLLECTED BY INHALED GASES AND SERVES TO PROVIDE ADDITIONAL MOISTURE TO SUCH INHALED GASES.
