En funcionamiento, la aguja se introduce inicialmente en la montura de catéter hasta que alcanza la posición aplicada de la lengüeta ilustrada en la figura 7B, en la que, como se muestra en ella, la lengüeta de bloqueo 118 está alojada dentro de la muesca o ranura 60 de la aguja. En este punto, la pinza elástica permanece en contacto con la pared interna de la montura de catéter en los puntos a, b y f, mientras que la punta de la aguja 18 se aplica al extremo curvado 114, empujando con ello a la sección 110 hacia la ranura 48 en el punto c. La posición relativa del punto f con respecto al punto b evita que la aguja y la pinza sean liberadas prematuramente de la montura de catéter, evitando que el extremo distal de la pinza bascule hacia arriba y el extremo proximal se deslice hacia abajo con la pinza en la posición aplicada de la lengüeta mostrada en la figura 7B.
A medida que la aguja es retirada del paciente, tal como se muestra en la figura 7C, la punta de la aguja pasa más allá del extremo curvado 114, liberando con ello la fuerza descendente que ha sido previamente ejercida sobre el extremo curvado 114 por parte de la aguja.
Esta repentina liberación de la fuerza descendente sobre el extremo de la pinza elástica determina que el extremo distal de la pinza elástica 96 pivote hacia arriba, de modo que el extremo distal 112 de la pinza elástica 96 se mueve rápidamente a una posición en la que evita o bloquea el movimiento de la aguja en la dirección distal. La pinza elástica 96 es retenida en la aguja 16 y será separada de la montura 26 de catéter cuando se haya retirado por completo la aguja. El movimiento de la pinza elástica 96 desde su posición protegida o retraída mostrada en la figura 7C se evita adicionalmente mediante la inserción de la lengüeta de bloqueo 118 en la muesca 60 de la aguja que evita que la pinza elástica gire alrededor de la periferia de la aguja. Esto, a su vez, asegura a la pinza elástica sobre la aguja, incluso si la pinza se sometiera a una fuerza de torsión y estiramiento.
El catéter IV de seguridad ilustrado en las figuras 7D y 7E es el mismo que el ilustrado en las figuras 7A y 7B, excepto que la ranura 60 en el cuerpo de la aguja en esta última está reemplazada en la primera por un saliente 61, cuyo diámetro es mayor que el de la abertura 58 en el brazo vertical 54. Si se realiza un intento para mover la aguja protegida ilustrada en la figura 7D en la dirección trasera o proximal, el saliente 61 se aplicará a la pared 54 y no será capaz de atravesar la abertura 58, con el fin de evitar cualquier movimiento proximal adicional de la aguja y la separación de la aguja de la protección de la aguja, según se desee.
La realización de la protección de aguja de pinza elástica 120 descrita en las figuras 10A, 10B y 11 comprende primeros y segundos brazos 122 y 124, respectivamente unidos en sus extremos proximales en una disposición abisagrada en 125 a los extremos de una pared trasera 126. Los extremos distales de los brazos 122 y 124 incluyen cada uno un saliente 128 curvado que se extiende hacia una pared extrema distal 130 que, a su vez, termina en un reborde 132. Tal como se observa mejor en la figura 11, la pared trasera 126 incluye una abertura central 134 y los brazos 122 y 124 incluyen cada uno una porción estrecha 142 que se extiende entre una porción ancha distal 140 y una porción ancha proximal 144. Un borde de fijación 146 lateral está definido en la porción ancha distal 144.
Tal como se muestra en la figura 10A, cuando la protección de aguja 120 se encuentra en su posición preparada, los salientes curvados 128 en cada uno de los brazos 122, 124 están alojados en una muesca anular o anillo 136 formado en la pared interna de una montura 26 de catéter que, como en las realizaciones previas, se fija de manera separable en el extremo distal de una montura 12 de la aguja. También, como en la realización anterior, una aguja 16 que tiene una punta afilada 18 en su extremo distal está alojada dentro de un catéter tubular 24 que está asegurado al extremo distal de la montura 26 de catéter. El extremo proximal de la aguja 16 atraviesa la abertura 134 en la pared trasera 126. La aguja 16 incluye un saliente 138 de diámetro incrementado que es lo suficientemente pequeño como para permitir que la aguja 16 se mueva axialmente a lo largo del catéter 24, pero mayor en diámetro que la abertura 134 por razones que se describirán más adelante.
En la posición preparada ilustrada en la figura 10A, el vástago de la aguja atraviesa la protección de la aguja y aplica una fuerza radial externa sobre los brazos elásticos 122, 124 por medio de su aplicación con rebordes 132, con el fin de empujar los salientes curvados 128 de cada uno de los brazos a la muesca anular 136, con el fin de retener la protección 120 de la aguja en una posición fijada dentro de la pared interna de una montura 26 de catéter. El cuerpo de la aguja 16 que atraviesa la protección 120 de la aguja se aplica con fricción en los bordes internos de las partes estrechas 142 de los brazos 122, 124 con el fin de retener adicionalmente a la aguja en su posición preparada.
Cuando la aguja se retrae axialmente, hacia la derecha tal como se observa en la figura 10A, dentro de la montura de catéter, y se desplaza más allá del reborde extremo 132 de la protección de aguja, la fuerza radial previamente ejercida sobre los brazos 122, 124 de la protección 120 de la aguja se libera repentinamente. Esto determina que las paredes extremas distales 130 de la protección de aguja sean liberadas de su asiento en la muesca anular 136 y que pivoten hacia dentro hacia la montura de catéter hasta que, tal como se observa en la figura 10B, las paredes extremas 130 se solapen una con otra en una ubicación distal delante de la punta de la aguja, para formar con ello una barrera que evite un contacto inadvertido con el movimiento distal de la punta de la aguja. Al mismo tiempo, los bordes de fijación 146 de la protección de la aguja son empujados contra la punta de la aguja para restringir adicionalmente el movimiento axial de la aguja.
Tal como se muestra también en la figura 10B, la protección 120 de la aguja y la aguja fijada a la protección de la aguja después de la retracción de la aguja puede ser separada de la montura de catéter como un conjunto unitario y puede ser desechada de manera segura. Si se realiza un intento de estirar de manera intencionada o inadvertida la

aguja más allá hacia la derecha, tal como se observa en la figura 10B, fuera de la protección de la aguja, el saliente 138 en el cuerpo de la aguja entrará en contacto con la pared extrema 126, y dado que su diámetro es mayor que el de la abertura 134, la pared extrema 126 evitará en este punto cualquier movimiento axial adicional de la aguja fuera de la protección de la aguja.
La protección de pinza elástica de la invención, en la realización ilustrada en las figuras 12, 13A y 13B, incluye un brazo transversal 150 que termina en su extremo distal en una pared extrema distal 152, que incluye en su extremo superior un reborde curvo 154, y en su extremo inferior un extremo curvo 156. Una abertura o ranura 158 rectangular alargada se proporciona en el brazo transversal 150. Los extremos proximales del brazo 150 de transferencia y la abertura 158 terminan en una prolongación 160 que se extiende hacia arriba formando un ángulo con el brazo 150 y que tiene un dedo o lengüeta 162 que se extiende hacia la abertura 158.
El extremo proximal de la prolongación 160 termina en un extremo curvo 166 desde el que se extiende una pared extrema proximal 168 hacia abajo. La pared 168, que incluye una abertura 170, termina en su extremo inferior en una sección curva 172, desde la que se extiende un brazo 174 inclinado hacia arriba que termina en un borde 176 de fijación. Como puede verse en las figuras 13A y 13B, una muesca circular 178 de 360º está formada alrededor de la pared circunferencial de la aguja 16 ligeramente hacia el interior desde la punta 18 de la aguja.
En la posición preparada de la protección de pinza elástica de la figura 12, como se ilustra en la figura 13A, el cuerpo de la aguja pasa a través de la abertura 170 en la pared trasera 168 y la abertura 158 en el brazo transverso 150 alineadas, y se extiende en dirección distal más allá de la montura de catéter. Como en las realizaciones anteriores aquí descritas, el cuerpo de aguja en esta posición ejerce una fuerza radial hacia abajo sobre el brazo 150 por medio de su aplicación con el reborde curvo 154. Esta fuerza hacia abajo empuja el extremo curvo 156 de la pinza elástica para que asiente firmemente dentro de una ranura 164 formada en la pared interior de la montura de catéter en el punto a.
Al mismo tiempo, el extremo curvo superior 166 de la pared extrema 168 se aplica con la pared interior de la montura de catéter en el punto b, y el extremo curvo inferior 172 de la pared 168 se aplica con la pared interior de la montura de catéter en el punto f. Se proporciona una mayor aplicación entre el cuerpo de aguja y la pinza elástica mediante el contacto del dedo 162 con el extremo superior del cuerpo de aguja en el punto e, y entre el borde 176 de fijación y la superficie inferior del cuerpo de aguja en el punto g. De esta manera, la aguja se retiene de modo seguro pero movible dentro de la montura de catéter en su posición preparada.
Cuando la aguja está retraída axialmente, hacia la derecha como se ve en las figuras 13A y 13B, finalmente se mueve más allá de su aplicación con el labio 154, para liberar repentinamente así la fuerza radial que previamente se había ejercido sobre el brazo 150 de la protección de aguja. Esta liberación de la aplicación entre el cuerpo de aguja y el reborde 154 permite que el extremo curvo distal 156 de la pared 152 extrema distal de la pinza elástica sea liberado de su asiento en la ranura anular 164, de modo que el brazo 150 y la pared extrema 152 pivotan rápidamente en el interior de la montura de catéter, como se ve en la figura 8B. a una posición en la que la pared 152 forma una barrera a la punta de aguja. Este posicionamiento de la pared 152 impide el contacto inadvertido con la punta de aguja. La aplicación del dedo 162 y el borde 176 de fijación en lados opuestos de la aguja impide más movimiento axial de la aguja en cualquier dirección.
Si después de ello se intenta tirar de la aguja axialmente más hacia la derecha, como se ve en la figura 13B, el dedo 162 entrará en la ranura circular 178 formada en la superficie de la aguja, para impedir de ese modo más desplazamiento axial de la aguja en la dirección proximal fuera de la protección de aguja.
Se apreciará por tanto que la protección de aguja de pinza elástica de la invención como se emplea en el catéter IV proporciona protección automática y fiable de la punta de aguja tras la retracción de la aguja para impedir el contacto accidental del personal sanitario con la punta de aguja. Se apreciará también que se pueden hacer modificaciones a las realizaciones de la invención específicamente descritas antes en esta memoria sin apartarse del alcance de la invención.
