摘要：
A vascular access device comprising: an intravenous catheter adapter having a proximal end, a distal end and a first light (42) extending therethrough； a diaphragm (43, 73) located within the first light, the diaphragm dividing the first light into a distal portion and a proximal portion； a pusher (44, 74, 114) disposed within the proximal portion of the first light (42), the pusher having a distal end (45, 75), a proximal end (46, 76) and a second light (47, 77, 117) extending therethrough； characterized by at least one flow channel (30, 50, 80, 80a) separated by ribs (49, 79), each flow channel defining a space between an external surface (54) of the pusher (44) and the internal surface ( 53) of the first light (42), the at least one flow channel being connected through a hole (51, 81, 81a, 121) with the second light (47), the diaphragm (43, 73) comprising a slit, and the pusher (44, 74) being slidably positioned within the first light (42), so that when the pusher slides towards the distal end of the catheter adapter, the distal end of the pusher advances through the diaphragm groove, thereby providing fluid communication between the distal portion and the proximal portion of the first light (42) by means of at least one flow channel (30, 50, 80, 80a) and the second light (47 ).Un dispositivo de acceso vascular que comprende: un adaptador de catéter intravenoso que tiene un extremo proximal, un extremo distal y una primera luz (42) que se extiende a través del mismo； un diafragma (43, 73) situado dentro de la primera luz, dividiendo el diafragma la primera luz en una porción distal y una porción proximal； un empujador (44, 74, 114) dispuesto dentro de la porción proximal de la primera luz (42), teniendo el empujador un extremo distal (45, 75), un extremo proximal (46, 76) y una segunda luz (47, 77, 117) que se extiende a través del mismo； caracterizado por al menos un canal (30, 50, 80, 80a) de flujo separado por nervaduras (49, 79), definiendo cada canal de fluj
