Abstract

BOLSA DE SANGRE DE PLASTICO QUE INCLUYE UNA BOLSA (3) QUE TIENE UN SELLO GENERALMENTE LONGITUDINAL (3) QUE SE EXTIENDE DESDE LA PARTE SUPERIOR DE LA BOLSA (3) Y ENTRE DOS PORTILLAS DE LA BOLSA DE SANGRE (17A, 27A) HACIA ABAJO HASTA AL MENOS LA MITAD INFERIOR DE LA BOLSA (3) PERO NO HASTA EL FONDO DE LA BOLSA (3) DEJANDO POR TANTO UN SOLO PASAJE (3D) DENTRO DE LA BOLSA (3) Y ENTRE LAS DOS PORTILLAS (17A, 27A) SITUADAS EN LA MITAD INFERIOR DE LA BOLSA (3). UN UNO DE LOS USOS SE INTRODUCE SANGRE ENTERA EN LA BOLSA (3) Y LUEGO SE LA CENTRIFUGA PARA FORMAR UNA PORCION DE PLASMA MAS LIGERO (9) Y UNA PORCION DE SANGRE ROMAS MAS DENSA (11). LA PORCION DE CELULAS ROJAS DE SANGRE (11) PUEDE ENTONCES EXTRAERSE DE LA PARTE INFERIOR DE LA BOLSA (3) APLICANDO PRESION A LA BOLSA (3) PARA EMPUJAR SUBSTANCIALMENTE TODAS LAS CELULAS ROJAS DE LA SANGRE POR EL PASAJE (3D) A UN LADO DEL SELLO LONGITUDINAL (3F) Y FUERA DE LA BOLSA (3) A TRAVES DE LA PORTILLA (17A) QUE COMUNICA CON ESE LADO DEL SELLO LONGITUDINAL(3F). EN INCORPORACIONES PREFERIDAS, EL SELLO LONGITUDINAL (3F) ES GENERALMENTE PARALELO Y SE CIERRA A UN LADO DE LA BOLSA (3) Y TERMINA EN SU PORCION INFERIOR DENTRO DE LA LONGITUD INFERIOR 10% DE LA BOLSA. EN INCORPORACIONES MUY PREFERIDAS, EL VOLUMEN DEL LADO POR EL QUE SALE EL COMPONENTE MAS DENSO DE LA BOLSA (3) ES MENOR QUE EL 3% DEL VOLUMEN TOTAL DE LA BOLSA. EL SISTEMA PREFERIDO SE PUEDE UTILIZAR COMO PARTE DE UN SISTEMA DE BOLSA DE SANGRE CERRADO MULTIPLE CON MEDIOS DE CONTROL ELECTRONICOS PARA PROPORCIONAR UNA SEPARACION DE SANGRE SEMI-AUTOMATICA
