Abstract:
A removable tip cap fore syringe, the syringe having a syringe barrel defining a fluid chamber and an elongated tip projecting from a distal end of the syringe barrel, the tip defining a first diameter, wherein the tip has a narrow passage that extends therethrough and which communicates with the fluid chamber of the syringe barrel, the tip cap comprising:a body having an outer surface, a proximal end, a distal end, and a cavity extending into the body at the proximal end thereof, wherein an inner surface of the body defines the cavity and the cavity has a proximal end defining a second diameter and a distal end defining a third diameter, the second diameter of the proximal end of the cavity is larger than the third diameter of the distal end of the cavity and the third diameter of the distal end is larger than the first diameter of the syringe tip, the inner surface of the cavity having en annular ridge extending into the cavity and defining a contact area to engage the tip of the syringe, wherein the contact area of the annular ridge decreases a surface area of contact between the tip cap and the syringe tip, and wherein the annular ridge creates an annular seal with the syringe tip.
