Abstract

JERINGA AUTOMATICA, PRESURIZADA Y PRECARGADA, CARACTERIZADA POR SER UN DISPOSITIVO DE FORMA CILINDRICA QUE ALOJA EN SU INTERIOR UN CONJUNTO DE CAMARAS SOMETIDAS A DIFERENTES PRESIONES POSITIVAS Y NEGATIVAS. PRESENTA TRES MODALIDADES DIFERENTES: LA PRIMERA MODALIDAD FIGURA 1, CONTIENE UN VOLUMEN DE MEDICAMENTO EN ESTADO LIQUIDO DISPUESTO PARA SU ADMINISTRACION INMEDIATA POR VIA PARENTERAL. LA SEGUNDA FIGURA 2, ALBERGA EN SU INTERIOR A UN DETERMINADO FARMACO DESDOBLADO EN DOS COMPONENTES (FRACCION SOLUBLE Y DISOLVENTE), PERFECTAMENTE AISLADOS ENTRE SI. PERMITE EFECTUAR LA RECONSTRUCCION DEL FARMACO Y SU POSTERIOR ADMINISTRACION. LA TERCERA FIGURA 3, PERMITE EFECTUAR EXTRACCIONES DE SANGRE, MEZCLARLA CUANDO CONVENGA CON DIVERSOS ADITIVOS Y ALMACENARLA EN UN VARIABLE NUMERO DE TUBOS HASTA EL MOMENTO DE PROCEDER A SU ANALISIS. EN TODOS LOS CASOS, LA AGUJA QUE PRESENTA CADA MODALIDAD SERA SECUESTRADA POR LA JERINGA AL FINAL DEL PROCESO DE LA INYECCION O LA EXTRACCION. MODALIDAD 1: INYECTORA. CONSISTE EN UN CILINDRO (1), ATRAVESADO POR UN TUBO DE PEQUEÑO DIAMETRO (2), SITUADO EN SU INTERIOR Y CONCENTRICO CON EL, FIGURA 1. DENTRO DE ESTE TUBO, Y MUY AJUSTADO, SE LOCALIZA EL EJE DEL EMBOLO (8). PUEDE ROTAR EN SU INTERIOR SIN DESPLAZARSE, AL ESTAR LIMITADO SU MOVIMIENTO EN LA PARTE SUPERIOR POR LA CABEZA DEL EMBOLO (10), Y EN LA INFERIOR POR SU RODELA (11), SOLIDARIA CON EL. POSEE CUATRO CAMARAS: LA CAMARA DEL MEDICAMENTO (3), QUE CONTIENE EL FARMACO EN ESTADO LIQUIDO Y POSEE UNA MODERADA PRESION NEGATIVA. LA CAMARA DE PRESION POSITIVA (5), CONTIENE UNICAMENTE AIRE COMPRIMIDO Y ESTERIL, CAPAZ DE ANULAR LA PRESION NEGATIVA QUE HAY EN LA CAMARA DEL MEDICAMENTO, Y AUN DESPUES CONSERVAR UNA FUERTE PRESION POSITIVA. EN LA CAMARA DE VACIO (6), POSEEMOS UNA INTENSA PRESION NEGATIVA. LA CAMARA RECEPTORA DE LA AGUJA (7) POSEE UNA PRESION ANALOGA A LA ATMOSFERICA Y EN SU PARTE INFERIOR PRESENTA UNAS LENGUETAS (17). CADA UNA DE LAS CAMARAS POSEE UN ORIFICIO DE PASO (43). LA PARTE SUPERIOR DEL CILINDRO (30) POSEE TRES AGUJEROS: EL ORIFICIO MAYOR (40), ES ALGO SUPERIOR AL QUE PRESENTA LA BASE DEL CONO DE LA JERINGA (24). EL DE MENOR TAMAÑO (41), COINCIDE CON EL ORIFICIO QUE POSEE EN SU INTERIOR LA BASE DEL CONO DE LA JERINGA. EL ORIFICIO CENTRAL (42), LO CONSTITUYE EL EXTREMO SUPERIOR DEL TUBO. EL EJE DEL EMBOLO (9) POSEE UN ENTALLE (12) Y EL CONDUCTO DE PASO INFERIOR (34). SITUADO SOBRE LA PARTE SUPERIOR DEL CILINDRO, SE UBICA EL CABEZAL (16). ALREDEDOR DE EL, SE LOCALIZA SU RESALTE ANULAR (27), EL CUAL PUEDE SER DESPLAZADO SOBRE LOS FIADORES DE BOLA (25) SITUADOS EN EL TERCIO SUPERIOR DEL CILINDRO. DEBAJO DEL CABEZAL SE ENCUENTRA LA JUNTA HERMETICA (37). AMBOS POSEEN UN ORIFICIO CENTRAL (35 Y 38) Y SON ATRAVESADOS POR EL EMBOLO, CUYA CABEZA SE SITUA CUBRIENDO EL ORIFICIO PERTENECIENTE AL CABEZAL. TANTO ESTE ULTIMO COMO LA JUNTA POSEEN ADEMAS SUPERPUESTOS OTRO ORIFICIO LATERAL DE MENOR TAMAÑO (36 Y 39), QUE EN EL CASO DE LA JUNTA PRESENTA ADEMAS UN AVELLANADO CILINDRICO Y ALOJA EL CONO DE LA JERINGA (23). SOBRE ESTE CONO SE SITUA EL CONO DE LA AGUJA (21). MODALIDAD 2: INYECTORA-MEZCLADORA. EN ESTA MODALIDAD SE INCORPORA UNA NUEVA CAMARA, LA CAMARA DEL DISOLVENTE (4), QUE INICIALMENTE PRESENTA UNA LIGERA PRESION POSITIVA Y CONTIENE AL DISOLVENTE. LA CAMARA DEL MEDICAMENTO (3), CONTIENE AHORA UNICAMENTE LA FRACCION SOLUBLE DEL MISMO, JUNTO CON UNA MODERADA PRESION NEGATIVA. EL EJE DEL EMBOLO PRESENTA UN NUEVO CONDUCTO DE PASO, EL SUPERIOR (33). LOS DEMAS ELEMENTOS DE ESTA MODALIDAD NO SUFREN VARIACION CON RESPECTO A LA PRIMERA. FIGURA 2. MODALIDAD 3: EXTRACTORA. FORMADA POR UN CILINDRO (44), ABIERTO EN SU EXTREMO INFERIOR FIGURA 3. CONTIENE EN SU INTERIOR LA CAMARA RECEPTORA DE LA AGUJA (57) CON SUS CORRESPONDIENTES LENGUETAS EN LA PARTE INFERIOR (17), Y UN VARIABLE NUMERO DE TUBOS (45) QUE SE ENCUENTRAN PRECARGADOS CON DIVERSAS SUSTANCIAS TALES COMO ANTICOAGULANTES, ADITIVOS, ETC. TODOS ELLOS POSEEN, ADEMAS, PRESIONES NEGATIVAS EN SU INTERIOR SUFICIENTEMENTE INTENSAS COMO PARA PERMITIRNOS ASPIRAR EXACTAMENTE EL VOLUMEN DE SANGRE QUE PRECISEMOS. LA CAMARA RECEPTORA DE LA AGUJA ALBERGA UNA MAYOR PRESION NEGATIVA. LA PARTE SUPERIOR DEL CILINDRO (46) POSEE CUATRO ORIFICIOS: TRES DE ELLOS (41), SE CORRESPONDEN CON EL QUE EL CONO DE LA JERINGA POSEE EN SU INTERIOR, Y EL CUARTO (40), ES ALGO SUPERIOR QUE EL DIAMETRO DE LA BASE DEL CONO DE LA JERINGA. TANTO LOS TUBOS COMO LA CAMARA RECEPTORA DE LA AGUJA POSEEN EN CADA UNO DE SUS EXTREMOS UN ALOJAMIENTO CILINDRICO, ENTRE LOS CUALES, Y MUY AJUSTADOS, VAN A QUEDAR ATRAPADOS. LOS SUPERIORES (47) ESTAN LOCALIZADOS EN LA PARTE SUPERIOR E INTERNA DEL CILINDRO, Y SE SITUAN ALREDEDOR DE CADA UNA DE SUS CUATRO ORIFICIOS. LOS INFERIORES (48) SE HAYAN EN EL INTERIOR DE UN TAPON ROSCADO (49), QUE AJUSTA POR MEDIO DE UNA ROSCA (51) EN LA PARTE INFERIOR DEL CILINDRO, Y PRESENTA UN MOLETEADO (50) PARA SU MEJOR MANEJO. EN EL CENTRO DE LA PARTE SUPERIOR DEL CILINDRO SE SITUA UNA ROSCA (52), DONDE SE ALOJA EL TORNILLO DE FIJACION(53). ALREDEDOR DE SU CUELLO (55), Y LIMITADO POR SU CABEZA (54) Y LOS FIADORES DE BOLA (25) ANALOGOS A LOS DE LAS MODALIDADES ANTERIORES, GIRA EL CABEZAL (16) CON SU JUNTA HERMETICA (37).
