Encoding and sensing of syringe information
DCFirst Claim
1. A syringe for use with an injector having at a plurality of sensors located at different predetermined longitudinal positions on the injector, the syringe comprising:
- a body comprising a wall and defining a longitudinal syringe axis;
an attachment mechanism to attach the syringe to the injector; and
a length of material disposed along at least a portion of the wall, the length of material adapted to propagate electromagnetic energy therethrough in a direction substantially parallel to the longitudinal syringe axis, the length of material comprising at least two indicators, each of the indicators being located at a different predetermined longitudinal position along the length of material, each of the indicators being positioned to longitudinally align with a sensor when the syringe is attached to the injector, each of the indicators being adapted to interact concurrently with at least a portion of the energy being propagated through the length of material in a direction substantially parallel to the longitudinal syringe axis in a manner that is readily detectable by the sensor in longitudinal alignment with the indicator, the at least two indicators providing information about the syringe configuration in the form of a binary code on the basis of presence or absence of one of the indicators at a predetermined longitudinal position on the length of material.

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.

10. A syringe comprising:
a body comprising a wall and defining a longitudinal syringe axis, a length of the syringe wall being adapted to propagate electromagnetic energy therethrough in a direction generally parallel to the longitudinal syringe axis, the syringe wall defining a plurality of indicators positioned at unique and different predetermined longitudinal positions therealong, each of the indicators being positioned at a different depth within the syringe wall so that each of the indicators are adapted to interact concurrently with at least a portion of the energy being propagated through the syringe wall to redirect light outside of the syringe wall in a manner that is detectable, the light redirected from the indicators providing a code that provides information about the syringe configuration. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
