摘要:
A syringe including a barrel (20) and a plunger (38) slidably disposed within the barrel is disclosed. A distal end of the barrel defines a roof, and an elongate tip, in fluid communication with the barrel, extends from the roof. A protrusion (56) forming a ridge is disposed on one of the roof of the barrel and the plunger head. When the plunger head contacts the roof , the protrusion forms a channel between the plunger head and the roof. The channel isolates fluid within the channel from the elongate tip, which in turn reduces the spray of fluid through the distal end of the syringe. In another embodiment to reduce the spray of fluid through the distal end of the syringe, an impulse reduction system may be used to reduce or prevent the proximal portion from applying a distally directed impulse to the distal portion after the breakable connection is broken.
