Encoding and sensing of syringe information
DCFirst Claim
1. A syringe, comprising:
- a syringe body comprising a sidewall defining a longitudinal axis, wherein at least a portion of the sidewall is configured to propagate electromagnetic energy emitted from an electromagnetic source incident on the sidewall by internal reflection in a direction substantially parallel to the longitudinal axis; and
at least one indicator recessed radially into an outer surface of the sidewall,wherein the at least one indicator is adapted to reflect at least a portion of the electromagnetic energy radially from the sidewall such that the reflected energy is detectable by a sensor to provide information about one or more parameters.

Abstract
A syringe for use with a powered injector to inject a fluid into a patient that includes a length of material adapted to transmit or propagate electromagnetic energy therethrough. The length of material includes at least a first indicator positioned along the length of material. The first indicator is adapted to interact with at least a portion of the energy being propagated through the length of material in a manner that is detectable. The presence (or absence) of the first indicator provides or corresponds to information about the syringe configuration. The indicator(s) of the present invention can, for example, provide information about syringe configuration by the number and/or position thereof. A plurality or set of such syringes can be provided, with the configuration of each such syringe being represented by the presence or absence of indicator(s) of that syringe.
