Abstract:
A dosing syringe, comprising:(a) a barrel defining a chamber therein for retaining fluid and including a dispensing port and a proximal opening communicating with said chamber for permitting fluid flow therethrough; (b) a plunger for being matingly received within the chamber through said proximal opening and axially moveable relative to said barrel for controlling fluid flow through said dispensing port, wherein the plunger comprises a first end for being matingly received through the proximal opening of the barrel, and a second end for manipulating axial movement of the plunger relative to the barrel, said plunger defining a compartment adapted for receiving a dosing indicator therein, said compartment being concentrically positioned within the plunger and communicating with a opening defined by and extending through said second end of the plunder; and (c) a dosing indicator carried by said plunger in said compartment and including indicia thereon collectively representing a dosing range of the fluid based upon a correlation between said indicia and a therapeutic treatment variable for a preselected group of patients, wherein said indicia cooperate with the plunger and barrel for measuring a medically correct dose of the fluid to be administered to a patient from the group.
