1. A device for monitoring the position of a plunger member slidingly engaged with a main body of a syringe, the device comprising:
- a housing structured to be selectively coupled to the main body in a readily removable manner; and
a monitoring system disposed at least partially on or in the housing, the monitoring system being structured to detect the absolute position of the plunger member with respect to the main body in a manner which does not require any mechanical linkage with the plunger member.

11. A plunger member for use with a main body of a syringe, the plunger member comprising:
-
a first end having an elastomeric member structured to slidingly engage an internal passage of the main body; a second end disposed opposite the first end and structured to be engaged by a user of the syringe; and a number of generally planar rib members extending between the first end and the second end, wherein one of the rib members comprises a gradient portion extending generally along the length thereof, and wherein the gradient portion has a transparency which varies in a predetermined manner along the length thereof. - View Dependent Claims (12, 13)

14. A system comprising:
-
a syringe comprising; a main body, and a plunger member slidingly engaged with the main body, the plunger member comprising; a first end having an elastomeric member structured to slidingly engage an internal passage of the main body; a second end disposed opposite the first end and structured to be engaged by a user of the syringe; and a number of generally planar rib members extending between the first end and the second end, wherein one of the rib members comprises a gradient portion extending generally along the length thereof, the gradient portion having a transparency which varies in a predetermined manner along the length thereof; and a device for monitoring the position of the plunger member with respect to the main body, the device comprising; a housing structured to be selectively coupled to the main body; and a monitoring system disposed at least partially on or in the housing, the monitoring system being structured to detect the absolute position of the plunger member with respect to the main body by determining an amount of light transmitted through the gradient portion. - View Dependent Claims (15, 16)
