Splatter prevention mechanism for a syringe

A syringe is described that includes a cylinder (20) and a plunger (38) slidably arranged within the cylinder. A distal end of the cylinder defines a roof, and an elongate tip, in fluid communication with the cylinder, extends from the roof. A projection (56) forming a ridge is provided on one of the roofs of the cylinder and the piston head. When the plunger head contacts the roof, the bulge forms a channel between the plunger head and the roof. The channel isolates fluid within the channel from the elongated tip, which in turn reduces fluid spray through the distal end of the syringe. In another embodiment to reduce fluid spray through the distal end of the syringe, a pulse reduction system may be used to reduce or prevent the proximal portion from applying a distally directed pulse to the distal portion after the seal is broken. breakable connection.
