Abstract

An adapter for releasably attaching a syringe to an injector. The adapter comprises a mounting mechanism positioned at a rear end of the adapter to mount the adapter in a desired position relative to a front wall of the injector; and a syringe carrier section adapted to seat at least a portion of the syringe. The syringe carrier section defines a first opening on a top thereof to allow placement of the syringe therein from the top and a second opening in a rear section thereof to allow the drive member of the injector to communicate forward force to the plunger. A cover portion extends over a rearward end of the first opening and has a first end configured to abut the flange of the syringe when the syringe is positioned within the syringe carrier section.

First claim

The invention claimed is:

1. A feedback and control system for a fluid injector, comprising:
an injector comprising at least one syringe port configured to receive a syringe adapter configured to receive a prefilled syringe therein to operatively connect the prefilled syringe to the injector; and
a control device in electronic communication with the injector, wherein the control device comprises a visual display having a user interface for guiding a user during operation of the injector, the control device being configured to:
receive information regarding the prefilled syringe containing a fluid to be injected to a patient;
determine a recommended syringe adapter based on the prefilled syringe containing the fluid to be injected to the patient; and
provide, on the visual display, an indication of the recommended syringe adapter to be connected to the at least one syringe port.

2. The feedback and control system of claim 1 ,
wherein the information regarding the prefilled syringe is received by at least one of an encoding device on the prefilled syringe, entering information on the user interface, or any combination thereof.

3. The feedback and control system of claim 1 , wherein the indication is a visual icon of the recommended syringe adapter.

4. The feedback and control system of claim 1 , wherein the control device is further configured to:
confirm that the syringe adapter connected to the at least one syringe port is the recommended syringe adapter; and
display a notification on the visual display if the syringe adapter connected to the at least one syringe port is the recommended syringe adapter.

5. The feedback and control system of claim 1 , wherein the control device is further configured to:
confirm that the syringe adapter connected to the at least one syringe port is the recommended syringe adapter; and
display a notification on the visual display if the syringe adapter connected to the at least one syringe port is not the recommended syringe adapter.

6. The feedback and control system claim 2 , wherein the encoding device is at least one of a bar code having spaced bars, a bar code having raised surfaces representing spaced bars, a slot, a hole, a projection designed to register against a switch on the fluid injector, optically readable devices, characters, dots, geometric shapes, a radio frequency identification device (RFID) tag, or any combination thereof.

7. The feedback and control system of claim 2 ,
wherein the at least one syringe port comprises a sensor for obtaining information from the encoding device about the syringe adapter connected thereto.

8. The feedback and control system of claim 7 , wherein the control device confirms that the syringe adapter connected to the at least one syringe port is the recommended syringe adapter based on a signal from the sensor for obtaining information from the encoding device associated with the syringe adapter.

9. The feedback and control system of claim 1 , where the control device is further configured to:
determine one or more injection parameters for an injection to be performed based, at least in part, on the recommended syringe adapter.

10. The feedback and control system of claim 8 , wherein the control device is further configured to:
confirm that the syringe adapter connected to the at least one syringe port is the recommended syringe adapter; and
produce audible information regarding whether the syringe adapter connected to the at least one syringe port is or is not the recommended syringe adapter.

11. A method of controlling a fluid injector system comprising an injector comprising at least one syringe port configured to receive a syringe adapter configured to receive a prefilled syringe therein to operatively connect the prefilled syringe to the injector; and a control device in electronic communication with the injector, wherein the control device comprises a visual display having a user interface, the method comprising:
receiving, by the control device, information regarding the prefilled syringe containing a fluid to be injected to a patient;
determining, by the control device, a recommended syringe adapter based on the prefilled syringe containing the fluid to be injected to the patient; and
providing, on the visual display, an indication of the recommended syringe adapter to be connected to the at least one syringe port.

12. The method of claim 11 , wherein the information regarding the prefilled syringe is received by at least one of an encoding device on the prefilled syringe, entering information on the user interface, or any combination thereof.

13. The method of claim 11 , wherein the indication is a visual icon of the recommended syringe adapter.

14. The method of claim 11 , further comprising:
connecting the syringe adapter to the at least one syringe port;
confirming that the syringe adapter connected to the at least one syringe port is the recommended syringe adapter; and
displaying a notification on the visual display if the syringe adapter connected to the at least one syringe port is not the recommended syringe adapter.

15. The method of claim 11 , further comprising:
connecting the syringe adapter to the at least one syringe port;
confirming that the syringe adapter connected to the at least one syringe port is the recommended syringe adapter; and
displaying a notification on the visual display if the syringe adapter connected to the at least one syringe port is the recommended syringe adapter.

16. The method of claim 12 , wherein the encoding device is at least one of a bar code having spaced bars, a bar code having raised surfaces representing spaced bars, a slot, a hole, a projection designed to register against a switch on the fluid injector, optically readable devices, characters, dots, geometric shapes, a radio frequency identification device (RFID) tag, or any combination, thereof.

17. The method of claim 12 , wherein the at least one syringe port comprises a sensor for obtaining the information from the encoding device about the syringe adapter connected thereto.

18. The method of claim 17 , wherein the syringe adapter connected to the at least one syringe port is confirmed to be the recommended syringe adapter based on a signal from the sensor for obtaining the information from the encoding device associated with the syringe adapter.

19. The method of claim 11 , further comprising:
determining, by the control device, one or more injection parameters for an injection to be performed based, at least in part, on the recommended syringe adapter.

20. The method of claim 18 , wherein the control device is further configured to:
confirm that the syringe adapter connected to the at least one syringe port is the recommended syringe adapter; and
produce audible information regarding whether the syringe adapter connected to the at least one syringe port is or is not the recommended syringe adapter.

21. A feedback and control system for a fluid injector, comprising:
an injector comprising at least one syringe port configured to receive a syringe adapter configured to receive a prefilled syringe therein to operatively connect the prefilled syringe to the injector; and
a control device in electronic communication with the injector, wherein the control device comprises a visual display having a user interface for guiding a user during operation of the injector, the control device being configured to:
receive information regarding a prefilled syringe containing a fluid to
