Abstract

A syringe including a barrel for retaining fluid and having a dispensing port for permitting fluid flow therethrough. A plunger is received within the barrel and is axially moveable relative thereto for controlling fluid flow through the dispensing port. A dosing indicator is carried by the plunger and includes indicia thereon collectively representing a dosing range of the fluid based upon a correlation between the indicia and a therapeutic treatment variable for a preselected group of patients. The 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.

Claims

1. 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.

2. A dosing syringe according to claim 1, wherein said dosing indicator is removably positioned within said plunger for permitting alternative uses of said syringe.

3. A dosing syringe according to claim 1, wherein the indicia comprise preselected strips of color arranged in a fixed sequence on the dosing indicator.

4. A dosing syringe according to claim 1, wherein each of the indicia comprise a respective one of a series of chevrons positioned in spaced-apart relation along the length of the dosing indicator.

5. A dosing syringe according to claim 1, wherein said indicia comprise preselected words arranged in a fixed sequence on the dosing indicator.

6. A dosing syringe according to claim 5, wherein each of said words corresponds to a preselected color for permitting a color-blind individual to use said syringe.

7. A dosing syringe according to claim 3, wherein each of said strips of color is overlaid by a respective one of a series of reference marks.

8. A dosing syringe according to claim 1, wherein the compartment comprises an elongate slot.

9. A dosing syringe according to claim 8, wherein said slot comprises two integrally formed, elongate segments positioned perpendicularly to one another and extending parallel to the longitudinal axis of the plunger.

10. A dosing syringe according to claim 9, wherein said segments intersect with each other to form an X-shaped cross section extending perpendicularly to the longitudinal axis of the plunger.

11. A dosing syringe according to claim 1, and including an alignment indicator carried by said barrel for being aligned with a preselected one of the indicia on said dosing indicator, thereby permitting the medically correct dose of the fluid to be measured prior to administering the dose to the patient.

12. A dosing syringe according to claim 8, wherein said dosing indicator comprises an elongate insert having a cross-sectional shape complementary to a cross-sectional segment of said slot.

13. A dosing syringe according to claim 1, wherein said interior compartment comprises a plurality of equally spaced channels defined by and extending along the length of the plunger, each of said channels adapted for receiving the dosing indicator therein.

14. A dosing syringe according to claim 13, wherein the dosing indicator comprises an elongate insert.

15. A dosing syringe according to claim 14, wherein said insert includes a fold extending parallel to the longitudinal axis thereof for maintaining the insert in a stationary position within a preselected one of the channels.

16. A dosing syringe according to claim 12, wherein the insert comprises a flexible strip for being placed in a bent position within a preselected one of the channels, thereby maintaining said strip in a stationary position with the channel.

17. 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 plunger; and

(c) a dosing indicator removably positioned within a said compartment defined by, said dosing indicator including indicia thereon collectively representing a preselected series of colors corresponding to 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.

18. A method of measuring a medically correct dose of fluid for being administered to a patient, comprising the steps of:

(a) providing a dosing syringe including;

(i) 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;

(ii) 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 plunger; and

(iii) a dosing indicator carried by said plunger 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;

(b) assigning a predetermined one of the indicia to the patient using the therapeutic treatment variable;

(b) providing a container of the fluid;

(c) immersing the dispensing end of the barrel into the fluid; and

(d) using the plunger to withdraw the fluid from the container and into the chamber until said predetermined indicia is aligned with a reference mark on the barrel, thereby indicating the medically correct dose of fluid is in the chamber.
