Abstract
UNA JERINGA COMPRENDE, A PARTE DEL CILINDRO (1), UN EMBOLO (2) Y UNA AGUJA (3), UN TOPE DE SUJECION DE LA AGUJA (4), UN TOPE PARA EL ORIFICIO DE LA AGUJA (5), UN MUELLE (6) QUE CONECTA EL TOPE PARA LA SUJECION DE LA AGUJA Y EL TOPE DEL ORIFICIO DE LA AGUJA Y UN MECANISMO DE BLOQUEO DISPUESTO ENTRE EL CILINDRO (1) Y EL TOPE DE SUJECION DE LA AGUJA (4). EL MECANISMO DE BLOQUEO FUNCIONA DE MANERA QUE FIJE EL TOPE DE SUJECION DE LA AGUJA (4) HASTA LA FINALIZACION DE LA INYECCION DE MANERA QUE LA AGUJA NO SEA EMPUJADA AL INTERIOR DE LA PARTE TRASERA DEL CILINDRO (1), Y QUE SE LIBERE CUANDO EL EMBOLO (2) PRESIONE ADICIONALMENTE, POR EJEMPLO MEDIANTE UN SIMPLE MOVIMIENTO DEL DEDO, DESPUES DE LA FINALIZACION DE LA INYECCION, DE MANERA QUE EL TOPE DE SUJECION DE LA AGUJA (4) SEA EMPUJADO HACIA ARRIBA POR LA FUERZA DEL MUELLE (6), MEDIANTE LO CUAL SE INTRODUZCA LA AGUJA EN EL CILINDRO Y, AL MISMO TIEMPO, EL TOPE DEL ORIFICIO DE LA AGUJA (5) SE MUEVA PARA CERRAR EL ORIFICIO DE LA AGUJA (27) EN EL EXTREMO DEL CILINDRO (1). LA JERINGA HACE QUE NO SE PRODUZCAN ACCIDENTES PINCHANDOSE LOS DEDOS CON LA AGUJA (3) DESPUES DE LA OPERACION DE INYECCION O QUE SALGA SANGRE DEL PACIENTE QUE HAYA QUEDADO ADHERIDA A LA PUNTA DE LA AGUJA.
