1. An electronically controlled injector, comprising:
- a drive ram attachable to a plunger of a syringe mounted to said injector,a motor which advances and retracts said drive ram to thereby move said plunger toward and away from a nozzle located in the front of the syringe to inject fluid into or out of an animal subject,a display screen for producing displays which enable an operator to set operating parameters of said injector and initiate an injection,a control circuit controlling said motor to inject fluid into or out of an animal subject, generating displays for production on said display screen, and changing operating parameters of said injector in response to activities of the operator,wherein said control circuit generates a setup display enabling an operator to set at least a first operating parameter of said injector, and in response to said first operating parameter generates either a first or a second different sequence of initiation displays after each of a plurality of syringes are mounted to said injector and before causing said motor to move a plunger in a mounted syringe toward a nozzle located in the front of the syringe to inject fluid, thereby enabling the operator to configure the injector for each syringe and each injection, and whereinwhen said first operating parameter is set to a first value in said setup display, said control circuit generates said first sequence of initiation displays after each of said plurality of syringes is mounted to said injector, andwhen said first operating parameter is set to a second value in said setup display, said control circuit generates said second sequence of initiation displays after each of said plurality of syringes is mounted to said injector.

Abstract
A computer-controlled injector of the type having a motor which advances and retracts a plunger located within a syringe housing toward and away from a nozzle located in the front of the syringe to inject fluid into or out of an animal subject. The injector includes a display for querying the operator as to operating parameters for an injection, such as the capacity of the syringe, prior to an injection. The injector may be configured so as to generate a different sequences of displays prior to an injection, e.g., to not include a query as to the syringe capacity if the injector will not be used with syringes of differing capacities.

6. A method of controlling an injector of the type including a drive ram attachable to a plunger of a syringe mounted to said injector and a motor which advances and retracts said drive ram to thereby move said plunger toward and away from a nozzle located in the front of the syringe to inject fluid into or out of an animal subject, comprising
producing, on a display screen, a setup display enabling an operator to set at least a first operating parameter of said injector, producing, on a display screen, either a first or a second different sequence of initiation displays after each of a plurality of syringes are mounted to said injector and before causing said motor to move a plunger in a mounted syringe toward a nozzle located in the front of the syringe to inject fluid, thereby enabling the operator to configure the injector for each syringe and each injection, wherein said first sequence of initiation displays is generated after each of said plurality of syringes is mounted to said injector, when said first operating parameter is set to a first value in said setup display, and said second sequence of initiation displays is generated after each of said plurality of syringes is mounted to said injector, when said first operating parameter is set to a second value in said setup display.
