Abstract

SE PROPORCIONA UN DISPOSITIVO DE MUESTREO DE EXTRACCION DE SANGRE CON UN ALOJAMIENTO, UN CONJUNTO DE LANCETA, UN PORTA LANCETA QUE PUEDE MOVERSE EN LA DIRECCION DE CORTE, ENTRE UNA POSICION BLOQUEADA Y OTRA DE PUNCION Y UN MECANISMO ACCIONADOR DISPUESTO EN EL ALOJAMIENTO PARA HACER QUE EL PORTA - LANCETA PASE DE LA POSICION BLOQUEADA A LA POSICION DE PUNCION. EL CONJUNTO DE LANCETA LLEVA UNA LANCETA CON PUNTA CORTANTE, UN CUERPO DE LANCETA QUE TIENE AL MENOS DOS REBORDES ANGULARMENTE SEPARADOS QUE SE EXTIENDEN HACIA FUERA DESDE UNA PORCION CENTRAL DEL CUERPO DE LA LANCETA Y UNA TAPA PROTECTORA QUE CUBRE LA PUNTA CORTANTE DE LA LANCETA, ENCONTRANDOSE LA CAPA PROTECTORA FIJADA AL CUERPO DE LA LANCETA DE MANERA QUE DICHA TAPA SE PUEDA RETIRAR A TORSION DEL CITADO CUERPO. EL PORTA LANCETA TIENE DISPUESTA EN EL MISMO UNA ABERTURA, TENIENDO LA ABERTURA FORMA CILINDRICA Y ENCONTRANDOSE PRACTICAMENTE SIN OBSTRUCCIONES, DE MANERA QUE EL CUERPO DE LA LANCETA PUEDE INSERTARSE EN LA ABERTURA EN CUALQUIER ORIENTACION ANGULAR RESPECTO AL PORTA - LANCETA. EL DISPOSITIVO DE EXTRACCION DE SANGRE INCLUYE UN MECANISMO PARA IMPEDIR UN MOVIMIENTO ROTATIVO SIGNIFICATIVO DEL CUERPO DE LA LANCETA RESPECTO AL PORTA - LANCETA CUANDO EL CUERPO DE LA LANCETA SE DISPONE EN LA ABERTURA FORMADA EN EL PORTA - LANCETA Y CUANDO LA TAPA PROTECTORA ESTA SUJETA A UNA FUERZA ANGULAR SUFICIENTE PARA RETIRAR LA TAPA PROTECTORA DESENROSCANDOLA DEL CUERPO DE LA LANCETA. LA ABERTURA CILINDRICA FORMADA EN EL PORTA LANCETA PUEDE DEFINIRSE POR UNA SERIE DE SUPERFICIES INTERIORES CURVAS Y EL MECANISMO DE PREVENCION PODRIA DISPONERSE CON UNA SERIE DE RANURAS FORMADAS EN EL PORTA - LANCETA, SEPARANDO CADA UNA DE LAS RANURAS UN PAR ADYACENTE DE LAS SUPERFICIES INTERIORES CURVAS.
